Every craftsman who deals with products and parts made of metal or wood cannot do without homemade clamps. Previously, such a tool was produced in various modifications, from specialized to universal. The main task is to fix the workpiece for processing and joining operations. We will analyze how a do-it-yourself quick-clamp clamp is made in various variations.

Angle clamp

This type of do-it-yourself metal clamp is designed to fix two objects at a right angle and connect them to each other by any means, however, the main purpose is a jig for welding metal parts at an angle necessary for work. To make it properly you will need the following components:

Corners should be welded at a 90 degree angle to metal or steel plates. We fix the worm structure by welding, and screw the stud-knob into the working nut in order to assemble the stop at the end. The stop must be free to rotate. Then with reverse side it is necessary to drill a hole where we insert a metal rod as a lever. Incredible simple design and practicality of use have become the key to the popularity of such a clamp among all those who work with metal and products made from it.

Joiner's clamp

Such designs used in carpentry are of the following types:

• Standard clamp, which is the most popular or simple;
• In the form of a caliper for parts small size and operational fixation;
• Self-clamping clamp for milling processes and working with workpieces of various heights.

The first type is made from two pine blocks, lock nuts, rods, threaded lamb nuts and thrust washers. The manufacturing process is very simple:

1. We cut out working pliers from the bars, drill holes for the studs, taking into account a small backlash;
2. We screw the studs and counter them in the appropriate ways;
3. We provide convergence with nuts, made either in the form of wing nuts or standard nuts for improved tension.

The second option is used when prompt fixation of small parts is necessary. Production is carried out from small bars and thin-sheet plywood. The worm system is nuts for furniture and studs-collars. One stop is fixed, we fix it at the end of the guide rail, in which we cut out recesses to fix the moving mechanism.

There are both portable and stationary version such a design, where grooves are cut for movement with fastening of fixed stops. The clamp is a furniture nut, a hairpin and a knob. Due to this, it is possible to work with blanks of any dimensions.

The self-clamping design has a lever with an eccentric at the swivel end. We turn to a certain angle, a quick clamp is automatically obtained. The height is adjustable with a pin on the workbench. It is made individually for each matrix, depending on its purpose and the purpose of the work being carried out.

Pipe clamp

Welding metal pipes butt to butt is a complex operation. It is considered simpler to weld the pipe to the finished system. The design for such cases is made of a metal corner and steel plates. The halves of such a device should be fixed traditional method, namely threaded studs. As a result, a fairly simple and efficient design can be obtained, which will greatly facilitate the work when welding pipes with various designs.

There are other types of designs, including cams, belts and wire clamps, that can be useful for working with specific designs, including especially fragile and thin ones. However, their production is the subject of separate master classes and articles on specialized resources.

Homemade clamps are indispensable assistants for any craftsman working with metal and wood parts and products. To make them is quite simple and very exciting. Here it is important to observe the manufacturing technology, to find optimal instructions and videos. You can buy clamps, but they may not be suitable in the end due to the specificity of the blanks or work. That is why you should make clamps yourself. Good luck working with various blanks and making homemade quick-clamp clamps!

Do-it-yourself clamp is made according to a pre-prepared scheme. The tool is presented in the form of a clamp, which is used to fix various parts. Joiner's clamps are used for sawing, breeding saw teeth or sharpening it.

Quick clamp is a kind of manual vice, which is used for strong fixation of workpieces or parts.

Principle of operation

A quick-clamp clamp is a kind of manual vice, which is used to firmly fix workpieces or workpieces. The main elements of the device include a frame, a moving part, lips, a valve. Experts recommend making tools from iron.

The quick-release tool can be fixed with one hand. The object is inserted between the jaws, pressing it down with a movable system. Then the product is fixed with a valve. The advantages of the considered design experts include:

• light weight;
• the ability to capture large parts;
• high strength;
• transportation;
• fast work.

The quick release clamp is used for unclamping. To do this, you will need to dismantle the limiters and lips by turning the last elements over. With this tool you can process glass.

Elements

Do-it-yourself clamps made of light metal quickly fail. The parameters of such units do not exceed 2 m. To press the overall sheets of plywood, you will need to make a sliding home-made clamp.

To constituent elements design specialists include:

• frame;
• jaws for clamping;
• moving part;
• lever component.

The mobile design with the help of a thread changes the pitch between the jaws. From a constructive point of view lever device consists of levers and eccentrics. This tool is difficult to make at home.

To make a wooden clamp, the scheme and the following tools are used:

• threaded studs;
• slats;
• nuts;
• plywood.

The length of the studs should be 120 and 200 mm, and the diameter should be 5 mm. The size of plywood boards is 15x150x200 mm, and the parameters of 2 rails are 20x40x240 mm.

Step-by-step instruction

The production of a homemade clamp consists in the use of wooden bars made of oak, beech, birch or ash. Such instruments are fixed to working surface. In the bars with which the clamping part is attached, 2 holes are made. This technology provides a tight fixation of the nut with the stud.

To get stable and robust design, it is recommended to place the bottom bar flat.

The next step is to install plywood boards. A bar is attached to them. The bottom edge of the plywood must be placed 3 cm below the bar. The blanks are drilled. Studs are inserted into the holes obtained.

Plywood is used as a clamping element. Such clamps capture parts with a moving strip. The tool is fixed to the surface of the countertop with short pins. Long analogues determine the working stroke of the clamp. Nuts are a lever that fixes a moving element by adjusting the clamping force.

Homemade clamp for welding can be made from a hacksaw, 2 threaded studs and nuts. The last elements are inserted into the clamp connectors. The nuts are put on from the inside of the device. The resulting tool has 2 sizes. To prevent the body from breaking into 2 parts, the folding element is wrapped with electrical tape. The versatility of the resulting device lies in the possibility of its reverse transformation into a hacksaw. For fastening sliding design tools use steel fasteners. A homemade clamp is not recommended to be used to the limit of its capabilities. Otherwise, it will quickly fail. The universal clamp is made from a channel.

Its length depends on the maximum dimensions of the processed material. The thickness of the channel is selected taking into account the frequency of use of the future tool. Places for holes for bolts are placed along the axis of the channel. The last fasteners are welded to the thrust structure. Holes are cut with a welding machine. To achieve a tight stop fit, the nest is made in the form of a drop. A bolt is welded to the channel. The size of its head should correspond to the diameter of the socket.

The next step is to manufacture the clamping device. To do this, use a thick screw. The resulting tool is used when working with dimensional objects. Otherwise, 2 small clamps and a flexible insert are used. The material of the latter design must have a high degree of rigidity, and the plane must be curved. ends flexible insert pressed with 2 small clamps to plywood sheets. The plane is recommended to evenly press on the surface to be glued. Manufacturing Method homemade tool depends on the purpose of the device and the size of the workpieces.

In order to speed up and simplify the process of work, for example, when working with metal products, you will need a couple of angle clamps! In addition, after welding, the metal clamped into the clamp does not lead away as without it, and the angle remains 90 degrees.
It is not difficult to make an angle clamp with your own hands, it is enough to have on hand small remnants of profile pipe, hairpin, and of course bolts with nuts, which I think everyone has.

Visually, the clamp can be divided into two parts: the base and the clamping part.

First of all, we make the base from a professional pipe 25 * 60 as shown in the photo.

Base made of profile pipe 25*60

First, you can assemble it on tacks, then completely boil the seams and clean it well with a grinder.

Then, from the same pipe 25 * 60, we cut off two segments of 160 mm each and weld them along the edges. You need to cook only from the outside and from the ends, because. the workpiece will be pressed from the inside and the seam may interfere.

We weld the outer jaws 90 degrees to each other.

The outer and inner clamps must be exactly 90 degrees to each other, after welding, make sure that they have not moved or been pulled away.

The next step is to make a mount for the clamping part.

We cut off a segment from a 40 * 40 pipe 30 mm long and cut off one of the sides, making it the letter "P", then weld it to the base. To fix the screw, we need to drill two holes for 8 and a third (lower) hole for 10, so that the socket wrench goes into it (you will understand why later).

We make a mount for the screw.

With the first part finished, now proceed to the second.

From the same pipe 25 * 60 we make internal clamps (sponges), according to external parties I got 105 mm.

We press them with clamps to the external clamps and weld them together.

We make internal clamps.

We cut out two triangles 2 mm thick and weld to the internal clamps from above and below. We drill a through (in two triangles) hole at 8.

We weld two triangles and drill a hole.

To fasten the screw in one and the other parts, we weld nuts 8 and 14 together (as shown in the photo). We make two pairs.

We make a mount for the screw.

We screw one nut onto the screw, and for the second we need to prepare it.

We grind the screw in a circle a little more than the width of the nut and cut the thread at the end by 8. We put a washer on it, the main thing is that it be of a smaller diameter than the screw thread, put on a fastener welded from three nuts and tighten the bolt. The mount should rotate freely, and the groove was made so that during the rotation of the screw, the nut would not be screwed onto it, but would rotate freely.

A clamp is a clamping fixture that is used in working with wood and metal, paper and leather. In carpentry workshops, with the help of clamps, parts, boards and shields are glued together; during welding, parts of metal products are clamped tightly. In office work, they are used when filing documents for archiving, and in auto repair shops they clamp parts of the mechanism when repair work. The shoemaker with its help glues the soles better.

The clamp is desired part and at home. They can be used to attach a pencil sharpener to a desk or table lamp to bedside table. Even when changing the battery in a good expensive watch, you will need the help of a clamp to tightly close the case back. After all, with high-quality tightness, it closes very tightly.

You can buy a ready-made clamp in a store, but usually several different products are required in production at once, and they are quite expensive, so most craftsmen begin to think about making a clamp with their own hands.

Types of clamps

Required for work different types such clamping devices. They are made of metal or durable wood. They happen different shapes: F and G-shaped, tape, edge, pipe, quick-clamp, screw, angle or mounting. But no matter how the clamps differ in their design and appearance, the purpose of all devices is the same: to firmly fix the products for further processing or connecting parts to each other.

Angle clamp made of metal

Having made such a design on your own, you can firmly connect not only wooden, but also metal parts to each other. Use these clamps for welding.

To work, you need a steel corner having a thickness of 4 mm and a size of 40 mm, 50 mm plates, threaded studs, nuts, washers and rods, welding machine, drill.

At an angle of 90 degrees, you need to weld the plates to the corners. From each side, also attach by welding a worm structure, which is a small piece of a corner with a welded stop nut, into which a knob with a hole for a metal lever is screwed on top. On the opposite side, a thrust mechanism is assembled, consisting of two washers. The emphasis freely scrolls on a hairpin.

Such angle clamp- This secure fastening parts at a right angle, which can be used not only for welding, but also in a carpentry workshop when working with wood or plywood.

Simple model for gluing corners

To make such a clamp with your own hands, you will need four steel corners of the same size, a threaded stud, two wing nuts, a drill, and a welding machine.

Two corners are welded together at a right angle, getting an even square in cross section. The next step is to weld the threaded studs inserted into the drilled hole of the same diameter. Holes must also be drilled in the remaining corners. The ready clamp is easy to assemble. To do this, you just need to clamp the glued wooden details using wing nuts.

Bonding if needed large planes, you can take steel corners of greater length and install additional studs also from the bottom of the clamp.

Homemade tape clamp

This type of clamp is often used to make picture or photograph frames. Such a clamp is a universal mobile mechanism with which you can glue the corners of frames of various sizes.

For the manufacture of such convenient fixture 6 mm plywood is required, wooden beam ok, thick plywood 10-15 mm, jigsaw, screwdriver, metal square, simple pencil, thick tape with a clip, bolts, washers, wing nuts.

The first step is to make a "table". To do this, we take a rectangular sheet of plywood and fasten two screws on the bottom from two opposite sides. wooden bars. Next, you need to clearly measure and draw the diagonals along which cuts for the structure will be cut with a jigsaw.

The next step is to make four frame holders from thick plywood. First you need to cut 4 identical pieces of plywood rectangular shape, then using a metal triangle, draw identical right angles on one side and cut them out. You also need to make a slot for the bolt so that the clamp has mobility and can move left and right. To prevent the stretched tape from jumping off, you can cut a recess on the opposite side of the corner.

Clamp

This type of clamping mechanism is designed for work that does not require particularly strong and tight compression of parts, since it does not have a strong connecting effect. Such a clamp can temporarily and quickly fix the part, for example, when cutting. It works due to the eccentric located in the middle of one of the parts of the clamping device.

For manufacturing, you will need wooden bars or thick plywood, a metal plate, self-tapping screws, screws, bolts, a drill, a circular saw, sandpaper.

The first step is preparing wooden bars. Their shape can be different, at the request of the master. It doesn't play a big role. A cut is made in the back, about 6-7 cm. metal plate with pre drilled holes and bolted securely. On the moving part, the fasteners do not pass through the plate, but are located along the edges. The bar should move up and down.

Further work continues on the moving part. On the saw, a longitudinal cut is made, leaving a thin strip at the bottom. It will act as a clamp and should move. The cut is also made for the eccentric, which is screwed to the top of the part.

The eccentric is easy to do. With a compass on paper, draw a semicircle, the ends of which are connected by an angle. It turns out the form of a drop. Transfer the dimensions to thin plywood and cut it out with a saw. In order for this part to fulfill its role and put pressure on the moving part of the bar, we shift the center of the semicircle by 1 cm and drill a hole, attaching it to top bar screw. When turning the eccentric, the part is tightly fixed and quickly clamped.

Table clamp

Very easy to use and easy to perform desktop clamp. A wooden beam, a piece of plywood, bolts, a drill, a threaded stud and a metal stick for the lever are taken. Two bars are bolted onto a sheet of plywood, which are motionless on the table. Then the clamping device itself is installed.

A hole is drilled in one of the bars, into which a threaded pin is inserted, securely screwed into a smaller bar at a right angle. A lever is inserted into the free end for convenience. Very fast and easy, even a beginner can handle it.

Simple wood clip

Such G-shaped design designed to hold two planes when gluing. Having made several copies, you can fix all the corners. To work, you will need a wooden beam, plywood, a threaded stud, a nut, screws.

Having twisted three identical pieces of a wooden beam, we firmly fix it with the help of two rectangular pieces of plywood. Next, drill a hole for the stud. To make it move well, you can drive a nut tightly into a wooden beam, along which the stud will spin freely. The handle can be made at your discretion either wooden, or by inserting a simple lever from a metal stick.

Lamp installation

With the help of clips, you can rearrange the table lamp to a place convenient for reading: on desk, bed, nightstand or hanging shelf. The lamp on the clamp is convenient to use, therefore it is popular.

Quick clamps such as clamps can be used in all areas of life and production. Making them with your own hands is not difficult, you just need to allocate a little time and have a desire. Successful work!

If the master decides to perform some work from wood or metal, then he should process the part. But this can be done qualitatively only if this part is very firmly fixed with a clamp.

The old models of such a tool made it possible to work with only one hand, but now there are new models of this tool, which serves as an indispensable assistant to any master, and they are not only quick-clamping. but also allowing you to work with the part with two hands.

There are several types of such clamps:

Let us briefly describe each type of clamp. The first type is lever. This means that the work of such an assistant tool is based not only on axial work, but also on the work of levers. Often popularly they are also called clamps, which allow you to quickly fix the parts intended for processing.

Lever clamps do not require the master great strength, in order to clamp something with them, it only takes a little force. And in order for the parts to be clamped tightly and no longer able to move, it is necessary to use a lever that will do all the work for a person.

The design of such a lever clamp is quite simple, it can even be done with your own hands. This will require the main frame and some element, where just the main clamp can be. With the help of such an assistant tool, you can not only clamp parts and make them immovable, but also calculate the clamping force, which is important, for example, when gluing.

The remaining types of clamps differ from the first type and among themselves in that they have different clamping mechanism. Many of these types of tools - an assistant can be made with your own hands.

How to choose the right clamp when buying

Choosing a tool such as a clamp is not difficult, you just need to know a few rules that will be able to purchase such a tool - an assistant that will become indispensable for you when doing any type of work. First of all, you should pay attention to what your tool has a working stroke.

Moreover, it is worth paying attention to what is the distance between the elements - clamps. The higher the indicators for these two points, the better this tool will be for you. This will allow you to use clamps to work with parts, like large sizes, as well as small ones.

Varieties of screw clamp

In such a tool - an assistant, not a lever, but a screw, is put forward in the first place. Such a clamp is also popularly called a pipe clamp, as it is used to clamp pipes, which are usually used for plumbing work.

Such a tool is considered very strong and reliable in plumbing, as it is made of duralumin. By the way, such an instrument has also been used special mounting holes. so that it is convenient to fasten any part to the workbench during work. It will be quite difficult to make such a tool with your own hands and at home.

Now a few words about the mounting clamp, which is most often used in the construction of various objects. The main purpose of this tool is hold any building materials. such as, reinforced concrete slabs so that they can be processed with high quality.

Such a clamp is considered the most reliable for work, but if you study its design, you can easily understand that it is simple. Looking at the drawing, where its constituent elements are reflected, you can easily assemble it with your own hands.

The hand clamp has several options:

There are other options for this hand tool- assistant. In the people, such a clamp is called a spring clamp. This is due to the simple design and the same simple application. Therefore, it is easy to make such an assistant tool with your own hands.

Instructions for making a tool - an assistant with your own hands

To make a clamp, you must correctly step by step follow the steps that are described in the instructions. To begin with, we acquire those parts that are necessary for the manufacture of a tool - an assistant with our own hands.

To make a clamp, you will need the following items: several studs with threads of different diameters, nuts. that will fit in size, a few planks made of plywood, and a couple of slats.

The second step for making a clamp is to create a base. You can also make it yourself. To do this, it is worth fixing what you have already done on the table. Then we take the bars and, applying to the clamp, we drill holes where they are needed in order to press them tighter to the base of the table.

The third step is to make a clamp with your own hands. This will require those plywood boards that you prepared in advance. You must press them against the bars that are already fixed on the clamp, but in such a way that they are movable.

You must understand that the role of these boards in the tool that you make with your own hands is to be levers in the clamps. Now, using studs and nuts, it remains to secure this entire structure, which you made with your own hands.

But using such a tool - an assistant that you made with your own hands, you should understand that it is not very durable and it is difficult to talk about its reliability. But it can be great for doing many household chores, as long as they are not very difficult.

Simple making of a clamp with your own hands from improvised materials.

Hello to all DIY lovers! And in this article, I want to show one of the options for making a simple clamp from improvised materials. It will take quite a bit of time to make this homemade product, but on the farm this thing is very useful! Everyone, I think, knows where you can apply a clamp, especially if you like to do everything yourself!

So, for the manufacture of this homemade product, I used:

- a wooden block (a piece of a block remained from my previous homemade Homemade ladder "Swedish wall");

- hairpin by 8 (do the length at your discretion, I took 20 cm);

- working tool (screwdriver, jigsaw, multifunctional device, keys, crowns, etc.).

First of all, we mark the template of the future clamp on the bar.

Then, using a jigsaw, we cut out the blanks.

These are the bars you should get.

Now with the help of an MFP (by the way, Very handy thing for processing small workpieces) and special nozzle with sandpaper (who doesn’t have such a tool, you can just get by with sandpaper), we process the blanks.

Such beauty turned out, but to complete it, I also processed the future clamp with dark varnish.

I made holes with the help of a crown to hide the nuts in a bar and drilled through holes.

Now just putting it all together

And here is such a wonderful assistant I got!

How to make a clamp with your own hands?

Buying clamps is very expensive. Therefore, in order to avoid unnecessary expenses, it would be useful to know how to make a clamp with your own hands. Quite often, in the manufacture of furniture or wooden products, clamps are required in in large numbers. Especially if wooden crafts produced professionally. To make clamps on your own, you will need primitive improvised materials that everyone has available. In addition, the work process itself is not complicated and does not require professional skills, which will allow you to quickly create the necessary auxiliary tool.

Clamp diagram: a - parts, b - assembled, 1 - rectangular hole, 2 - pusher, 3 - body wall, 4 - ledge, 5 - hole in the body, 6 - clamping screw, 7 - movable jaw, 8 - lever, 9 - protrusion, 10 - threaded holes, 11 - screws.

What is a clamp, and is there any point in making it yourself?

A clamp is an auxiliary tool that is used to fix the boards when they are connected (using glue, fasteners, etc.) or, if necessary, to compress them. Usually clamps are made of metal or wood. A clamp is also used to cut boards evenly, to make wiring for a hacksaw, to connect various parts and elements, etc. Wherein homemade clamps are in no way inferior to the purchased ones. To understand the principle of making a clamp with your own hands, you should understand its design.

Scheme of the assembly of the corner clamp.

Such clamps consist of 2 elements - a “body” (frame) and a fixing element (movable clamp). There are clamping jaws on the movable element and the frame, and for better fixation, the movable element is equipped with a lever. Lever clamps are also sometimes found, but they are rare due to their difficulty in manufacturing, as in industrial enterprises as well as at home.

The operation of the clamps is simple: parts (or material) that require processing are inserted into the body of the tool, then the working material is clamped with a moving element (clamping occurs with sponges), after which you can start processing or working with parts or material.

In most cases, the number of clamps required for a particular operation is not limited to 1 pc. For a tight fixation of the hacksaw, use 2 pcs, for fixing wooden planks- from 2 or more (depending on their length). In addition, if you want to connect parts, it is recommended to use a pair of clamps. Many people forget to take them off after work is done, which often leads to the loss of the tool. And primitive factory-made metal clips are not cheap, which makes it cost-effective to make such tools yourself. Below we will consider how to make carpentry clamps from wood and metal, and how an angle clamp is made by hand.

Making a wooden clamp

It is much easier to make a wooden clamp than all other types of such a tool. Such clips are very convenient when performing various carpentry work.

The main materials needed to make a clamp.

To make them you will need:

• pieces of boards (you can plywood);
• studs (which should be pre-threaded);
• nuts (for threaded studs);
• slats.

For the manufacture of the clamp, two studs 200 mm long with pre-threaded threads and 2 studs 120 mm long should be prepared. It is important that all 4 studs have the same diameter. Next, nuts are selected under the thread of the studs, two rails are prepared. Reiki should be prepared from hardwood. Oak is ideal, but beech, birch or ash slats are also suitable.

Then the slats need to be made the same in size. To do this, saw off all the excess and produce grinding. Then 2 holes are drilled in each rail. The holes must be at the same points on each rail. The diameter of the holes must match the diameter of the studs.

The next step is to stick plywood (as sponges) on the surface of the slats. When the plywood is glued, all the protruding parts are cut to the size of the battens, and the plywood sponges themselves are drilled through the holes in the battens.

Hacksaw before modification and clamps obtained from it after modification.

Then long slats are inserted into the resulting holes. They will act as guides.

After the guides are installed, they are fixed with nuts to the rails. 2 nuts are screwed onto each guide.

Next, insert short studs. To make them immovable, the studs are riveted on one side. It is important that one stud is riveted from the back of one rail, and the other from the back of the other. Nuts are used as clamps. In order to make it more convenient to tighten them, lamb nuts are used. In this case, it is important to cut the threads on the fixing studs along their entire length.

This completes the manufacture of the wooden clamp.

How to make a screw metal clamp

To make such a clamp, you first need to prepare the materials. For the clamp body, you can use a sheet of steel about 1 cm thick or even and straight metal cuttings of the same thickness. The length of the workpiece depends on what working distance the clamp will have. For manufacturing, you will need long screws or bolts M8 or M10.

Clamp assembly diagram.

At the beginning of the manufacturing process, markings of the future tool body are applied to the workpiece material. Often the body of the instrument looks like the letter "C". In this case, the thickness of the workpiece can be different. It depends on the required length. working area. When the markup is applied, the part is cut out. To do this, at home use gas cutters, acetylene torches or a grinder. The grinder is used for workpieces of small thickness, it is problematic to use it when cutting out small curly elements.

When the workpiece is cut, it is polished with files, sandpaper. Grinding is an important process, if you do not grind the part, then there is a chance of cutting yourself on sharp edges when working with the tool.

Then, on one side, fasteners are made for the movable element. To do this, M8 or M10 nuts are welded to one of the sides of the clamp body. If there are no bolts or screws of sufficient length, hexagons or rebar of the desired length can be used. They should be threaded first. A flat flat part (on the working side) is welded to the end of the screw, which will act as sponges. A lever is welded on the opposite side (studs can be used as a lever), which should simplify the clamping process. This completes the manufacture of the clamp.

Another option is to make a clip like a caliper. For this, a sliding frame made of steel strip is used. The end of the strip is flattened, and sponges are welded to it. Further, a movable element is made from the same strip, to which nuts are welded and a screw is screwed in for fixation.

It is more difficult to make such a clamp, but it has a longer stroke and, accordingly, a larger working area.

A do-it-yourself clamp facilitates the work of the master and saves him money.

No master can do without a clamp. Whether it is a carpenter, or a metalworker, there is always a need to use it.

This device is available in different options from universal to specialized. Relatively recently, a new modification has appeared: a quick-clamp clamp. Develops compression force up to 450 kg.

The task for all types is common - to fix the workpieces for processing or connecting to each other.

Like any other tool - clamps can be purchased at the store or made independently. The second option is often chosen by professionals. It's easier to come up with own design than looking for an option for individual tasks.

Homemade clamp - varieties and manufacturing technologies

Such devices are used to fix two objects (not necessarily of the same size) at a right angle, to connect them together in any way. These can be wooden blanks when gluing, or assembling with the help of corners and confirmation.

However, most often, an angle clamp is used as a jig for welding metal parts at a right angle.

For manufacturing you will need:

• steel corner 40 mm, 3-4 mm thick;
• steel plates 40-50 mm wide;
• threaded studs, preferably hardened;
• bars for collars;
• nuts for the worm mechanism;
• welding machine;
• drill, taps.

We weld the corners to steel plates strictly at an angle of 90 °.

We attach a worm structure to each side by welding. This is the same corner with a welded stop nut or thickening, in which the thread is cut in accordance with the hairpin. The width of the working gap is selected for potential workpieces.

IMPORTANT! If the range of workpiece sizes is too wide, it is better to make several clamps. Too much stroke of the knob does not contribute to a strong fixation.

A stud-knob is screwed into the working nut, after which an emphasis is assembled at its end. As a rule, this is a design of two metal washers different sizes. The stop should scroll freely on the hairpin.

On the reverse side of the knob, we drill a hole into which we insert a metal rod as a lever.

A properly assembled metal clamp allows you to securely fasten steel parts during welding, or wood during carpentry. The design is so simple to manufacture - that it has become a real life among homemade craftsmen.

Carpentry option 1

The simplest wood clamp used in carpentry is made from the following materials:

1. Two blocks of wood and a non-solid but strong material. Pine will do. Too hard wood will leave marks on the workpiece with strong fixation;
2. Furniture nuts with a latch under a tree;

Steel studs, not necessarily expensive hardened steel;

Nuts - lambs with a thread corresponding to the studs;

Washers are persistent, you can also use ordinary, inexpensive ones.

Working pliers are cut out of the bars. Holes for studs are drilled in them strictly parallel, with a slight backlash.

The studs are screwed into furniture nuts and locked. Convergence is provided by lambs, or ordinary nuts with an open-end wrench (if a particularly strong grip is required).

ADVICE! If you make two sets of identical clamps, the scope will expand. Then you can use the device as a carpenter's vise.

Carpentry option 2

For quick fixation of small parts, a clamp is used, made in the form of a caliper.

The device is made of bars and thin plywood. The worm system is familiar - furniture nuts and a hairpin-knob. The fixed stop is firmly attached to one end of the guide rail. Recesses are cut out on the rail itself to fix the movable mechanism.

Having moved the bracket to the required distance, it remains to turn the knob a few turns, and the part is fixed. After releasing the stop mechanism, the carriage moves easily, freeing the workpiece.

The stationary version of this clamp has rail structure. On two guides installed in parallel - grooves are cut at the same distance. On them, with the help of metal rods, fixed stops are attached. They can be moved to the desired distance, according to the width of the workpieces. Fixed stops with a worm gear are installed at the end of the bars.

The clamp is carried out in the usual way - furniture nut, hairpin, collar.

Carpentry option 3

Sometimes it is necessary to simply press the workpiece against the processing table. For this, there is a self-clamping clamp. The illustration shows how to make metal or wooden brackets.

The principle of operation is simple - you need a lever with an eccentric at the swivel end. By turning it at an undefined angle, we get an automatic quick clamp. The overall height is adjustable with a pin fixed to the workbench.

It is possible to fix two clamps of this type on a mobile template for mass milling identical workpieces.

This type of quick-clamp clamps is made individually for each matrix, or rearranged on a new substrate for cutting out the next form.

Pipe clamp

Welding metal pipes end to end is a rather difficult task that requires precise orientation of the workpieces in space. If you weld a piece of pipe to a finished system fixed in a room, the task is simplified. And welding of free-lying segments requires an assistant or a special device.
