Production of simple and corner clamps with their own hands. The clamp makes it easier to the master and saves his money how to make a joinery clamp with their own hands: step-by-step instructions with drawings

Clamp is auxiliary tool , which is used to fix the boards when they are connected in a specified position. Also, the clamp is suitable for retention of boards during their sawing, for wiring hiscellular cloth, Connections various elements. The tool can be seen that require the processing of the part. Then, using a moving element, they are clamped using sponges and proceed to operation. For reliable deduction of parts in right position It is recommended to use two or more clamps.

Homemade fastenings are more often made of metals or wood, and in their characteristics they are little inferior to the purchased, factory assembly. Since the design of the presser device is simple, then understand the principle of its work to be made independently, it will be easy.

Production of screw metal clamp

Before starting work, you will need to prepare necessary materials. For the basis of the design, a steel sheet is suitable for a thickness of one centimeter, any smooth trimming of the same thickness. The length of the workpiece is arbitrary, but they are trying to choose to choose the work distance of the clamp.

Basic manufacturing materials:

steel sheet;
long bolts;
nut.

Drawing is drawn up. On the material of the workpiece, there is a future tool body, which looks like the letter "C". Instead of steel sheet, you can use a segment of a profiled pipe, bent in the form of the letter "C". Special requirements No billet thickness, but the design should be reliable. The choice of length is made with dimensions. working areaThe processed details.

After applying markup, the part is cut out of metal. At home workpiece small sizes You can cut with a grinder. But in the manufacture of large-scale clamps, it is recommended to use a gas cutter, acetylene burner. The next stage is the processing, grinding of the workpiece. Everything sharp edge, influxs formed when working with gas welding equipment, are knocked down using a file, and the surface is grouped emery paper. It is necessary to do that, clamping the blanks, do not cut down about sharp edges.

Prepare the long bolts M 8, M 10, proceed to the fastening of the moving element. For which the nuts under the selected bolts are welded on one side of the workpiece. In the absence of bolts, you can pick up hexagons, steel rods of the desired length with pre-sliced \u200b\u200bthreads.

A flat smooth part is welded on the inner working end of the screw, to which the sponge function is assigned. On the reverse side of the screw with the help of welding, the lever made of stripping trimming. Its presence will accelerate the process of clamping , Additionally, reducing the magnitude of the effort applied. On this assembly of clamps with their own hands is completed.

Corner Crane Device

When making an angular tool for assembling furniture, it is important to accurately withstand the straight angle of 90 °. Basic affordable materials Are corners with steel stripes. For work you will need:

40 mm steel corner with a thickness of 3-4 mm;
steel plates 40-50 mm;
threaded hairpins;
rods for gates;
nuts;
welding machine;
electrode, taps.

The corner clamp is the most difficult thing in the manufacture, but when some types of work do not do without it. On the initial stage Corners are welded to steel plates at right angles, and each of the corners are nuts, which will serve to create a worm structure. Another option is to drill a hole in the corner and cut into it using a tap internal thread. The width of the working clearance is selected taking into account the magnitudes of potential billets, but too much the pressure of the clamping glow reduces the strength of their fixation.

For processing details various size It is recommended to prepare several clamps!

The stud is screwed into the welded nut. At her end, it is assembled from metal Syb. various diameterswhich should freely scroll when the stud is rotating. FROM back side The turnover is drilled under the metal rod. Used as a lever, it will transmit more effort, so it will be more reliable to keep working blanks.

Wooden clamp - make from the rest of the boards

The greatest popularity is the wooden high-pressure clamp, but the tool of a similar design can be made of metal. Despite the simplicity of the design, it is very convenient when performing various works.

The presence of two identical clamps expands the area of \u200b\u200btheir application!

For assembly, you will need to prepare the following materials:

pieces of boards;
studs with a pre-sliced \u200b\u200bthread;
nuts and lambs corresponding to the threads of studs;
rake.

First, two studs are prepared with the same diameter with chopped threads. They must have a length of 200 mm. Nuts are selected under the thread of the studs. Two rails are harvested, it is desirable from solid wood. The best choice There will be oak, beech, birch, ash. Rakes are adjusted under the same size. For this, the excess length is spawn, and the cut is grinding. After that, in each of the rails, two holes with a small tolerance are drilled. Moreover, the location of the holes on each of the blanks should be perfectly coincided, and their diameter correspond to the diameter of the studs.

On the surface of the rail can stick plywood strips. They are customized on the dimensions of wooden billets, drill holes. Studs are inserted into the resulting holes and securely fixed with nuts on one of the plates on both sides. To prevent the material to prevent the material, the washers are put under the nuts. This plank will always be fixed, but the other will be able to move freely on the guides in the form of studs.

Installed another plank. To do this, it has traveled through the hairpins, hesitate to the place. The clamp is carried out using conventional nuts and horn keyBut for convenience and improve performance it is necessary to install nut-lamb. Check the course of fasteners if it is difficult or needed an additional fitting of the parts, other defects were discovered, they are eliminated. Work on the assembly of the clamping device from the tree can be considered complete, it remains to try it in the case.

Corrected clamping devices allow you to securely secure wooden details When carrying out carpentry work. The designs of the listed species are fastened with popularity and are so simple that they can be made independently from the primary materials with the attraction of the minimum amount of tools.

Clamp is a tool that allows you to fix the item during processing. Masters are often used different kinds Clamps in his work. Whether it's a joiner, or a metal-machined machinemer - there is always the need to use it.

This device is produced in different versions, from universal to specialized. A new modification appeared relatively recently: a quick-sigh clamp. Develops compression force up to 450 kg.

Task for all types of general - fix the blanks for processing or connections to each other.

Like any other tool - clamps can be purchased in the store or make yourself. The second option is often choosing professionals. It's easier to come up own constructionthan to look for an option for individual tasks.

Homemade clamps - varieties and manufacturing technology

Corner clamp

Such devices are used to fix two objects (not necessarily the same size) at right angles, to connect them with any way. It can be wooden billets when gluing, or assembling with the help of corners and confirm.

However, most often, the angular clamp is used as a conductor for welding metal parts at right angles.

For the manufacture you will need:

steel corner 40 mm, 3-4 mm thick;
steel plates with a width of 40-50 mm;
threaded hairpins, desirable hardened;
rods for gates;
nuts for the worm mechanism;
welding machine;
drill, taps.

Corners weld to steel plates strictly at an angle of 90 °.

For each side, secrets with welding worm design. It is the same corner with a welded nut or thickening, in which the thread is cut in accordance with the band-gorot. The width of the work clearance is selected for potential billets.

IMPORTANT! If the range of the size of the processed parts is too wide - it is better to make several clamps. Too much turn turns does not contribute to a solid fixation.

Screwdriver spill on the working guy, after which it is assembled at its end. As a rule, this design of two metal washers different size. The emphasis must be freely scrolled on the heel.

Repair and manufacture of furniture, various wooden or metal products are not possible without the use of clamps. Modern instrumental shops offer big choice These products. Conditionally, they can be divided into two large groups. The first combines the clamps using threaded parts. Clamps of this group are called screw. They may have a stationary bracket of one size or sliding.

In the second group, clips are combined using wire or flat springs and called, respectively, springs.

To any master for work may be needed to several dozen different clamps. Acquisition of such a number of instruments will require sufficient money. Much more economical to make clips on their own. About how to make various types of clamps with your own hands, will be discussed in the future.

Production of screw clamp

A simple screw clamp can be made, having a steel sheet with a steel sheet with a thickness of 8-10 millimeters, a ready-made rod with M8 or M10 thread and several nuts of the same size.

First, using a template or other finished clamp, perform markup of the bracket on the selected billet. At the same time, it is possible to take into account the requirements of the specific operating conditions of the clamp and make the bracket of the required size.

The next step is cutting the blank. The thickness and geometric shape of the workpiece of the future clamp makes a problematic application for this type of work of the Bulgarian. In this case, it is better to use acetylene burner or gas cutter.

At the stage of grinding the edges of the resulting bracket, an angular grinder can be used. Cover the edges according to the markup line and remove the corner burrs.

For the screw clamp on the short side of the bracket, breed several nuts M8 or M10. Instead, you can use a string of a six-year rod with a length of 40-50 millimeters with internal thread appropriate diameter.

For the work of the clamp, select a round rod with an appropriate threaded length. From one of the ends, breed a transverse handle to it.

To protect the finished clamp from corrosion, cover the surface of the product of any oil or nitrogen.

Production of screw clamp with sliding frame

If necessary, it is not difficult to make a clamp with a sliding frame.

The following materials will be needed for work:

steel strip cross section 40x (8-10) mm;
rod with a thread 10-150 mm long;
several nuts and round washers.

From the tools you should prepare a grinder, a drill and a welding machine, gas or electric.

The first stage - cutting the strip on the blanks of the required length. We will need a 500 - 800 millimeters rack, a support bar with a length of 200 millimeters and a mobile strap of the same length.

With the help of welding, attach to one of the ends of the long part stationary emphasis. To ensure maximum strength of the design, try to get seam high Quality, Pick the welding modes correctly.

The next step is to process the sliding strap. It needs to be placed and produce two holes, one of which is round, and the second rectangular shape.

Obtaining cylindrical holes in the presence of electric drills or drilling machine Will not be difficult. It is enough to find the drill of the corresponding diameter, it is securely clamping it in the instrument's cartridge and produce drilling. The diameter of the circular opening must exceed the diameter of the threaded rod.

The manufacture of a rectangular opening will require large time and energy costs. Rates from the edge of the plank of 25 millimeters, along the axial line, mark the rectangle 11 × 41 mm. A small gap will need for the free stroke of the plate at the rack. Next, mark the centers of the holes, retreating 5 millimeters from the edge of the groove and 10 millimeters from each other. In order to avoid slipping drill, the centers of the holes must be preached. Drill four holes with a diameter of 10 millimeters. Press the fine form by manually using a square and rectangular file.

Over the round hole of the sliding plank, weld the nut with a thread corresponding to the rod. To one of the ends of the screw, breed a transverse handle, to another round washer of sufficient thickness. Slide the edges of all parts from metal burrs with emery paper and build a clamping device.

Production of corner clamp do it yourself

The process of manufacturing a number of products, such as doors boxes, requires a connection of the parts at a right angle. For reliable fixation of components of wooden elements or metal structures Corner clamps are used.

Such a clamp can also be made of healthy materials yourself. You will need two trimming of the steel corner of 40x40, 50x50 or 30x50 to 200 millimeters each, a slide of the strip 10x50 with a length of 250 millimeters and two finished screw clamps.

Using a locksmith square without a pad to control rectangles, set all the design items according to the photo.

Via welding machine Attach the corners to the reverse side.

Also welding seam attach clamps to the bases for reliable fastening.

Thus, it will be convenient and reliable adaptationwhich repeatedly rescues you when performing a number of works.

Dear readers, if you have any questions, ask them using the form below. We will be happy to communicate with you;)

Anyone who had to make something with their own hands towards the improvement of their own dwelling, there is no need to talk about importance of different kind clamps and clamps. Without their presence, it is impossible to imagine both carpentry and plumbing craft. To qualitatively handle any detail, clamp is necessary. Its with your own hands it is possible to make at home with the most elementary tools.

Types and types of clamps

Mechanical clamping devices differ in both the intended purpose and the material from which they are made. The main source materials are a wooden bar.

Sometimes clamps collect a rather complex spatial configuration: they provide both horizontal and vertical compression of the workpiece processed. For assembly when constant control is required direct corner, very comfortable clamp corner. It is quite possible to make it possible, but it is better to practice less complex structures.

Located clamps and by type of elements that create mechanical compression. The most common clamps based on the screw mechanism. But to approach the design, everything that is capable of providing the necessary compression effort is possible. Up to the sliced \u200b\u200bfrom old car chambers.

Why not just buy them?

In any tool store, clamps are presented in a more or less wide range. Yes, and any master of them in the arsenal is available sufficient number. What usually stops the craftsman from buying another one? First, the price is quality instrument It may not be cheap by definition. SecondlyYou can not always find the necessary. Clamp, with his own hands made under the performance of a specific task, provides the process of assembling the product individually. With the help of a universal clamp, it is not always possible to achieve this from the instrument store.

Disadvantages of standard tools

In the construction market you can find a lot of clamps that look like real and are expensive, only work very long. They are usually Chinese production. They will have to be thrown out after the money, which were paid for them. Most often fails to be made from cheap low-quality alloy. If there is no desire to throw money to the wind, then you should think about how to make a clamp with your own hands. The result of this will not only be one useful thing In the instrumental arsenal of the master, but also the increased level of qualifications and self-esteem.

Clamp do it yourself: what is necessary for its manufacture

First of all, it is necessary to get a high-quality timber from solid hardwood wood or a segment of a metal rolling profile (better than a chamber section) is the basis on which the emphasis and screw mechanism must be mounted. The most important element of the clamp is it. Bolt is best for a bolt with a large thread profile nut. To assemble the design to a single whole, you will need a drill with nozzles and a standard bolk fastener. The manufacture of clamps does not require outstanding qualifications with their own hands, but still elementary carpentry and plumbing skills should be posted.

Making clamp

The most important advantage of self-made clamp is its narrow focus on ensuring a specific technological operation. That is why it is necessary to merge everything carefully and sketch schematic drawing future product. Clamp, with his own hands made, maybe it should serve for a very long time, but it will only happen if it is correctly designed and properly assembled.

At the bearing station, the stopper must also be mounted and screw mechanism. The free stroke of the screw provides sufficient effort to compress. The mounting of the stop and the screw with the nut should exclude them from the fixed position when the technological effort is applied. An important point is the presence of a flywheel mounted on the head of the technological screw. If it is not foreseen and not to fulfill it, then the compression of the clamp will have to be carried out with the help of what is not productively, and not functionally.

In order to use clamps as possible in larger quantities Operations are usually performed in the form of a removable block, which can be placed in several fixed positions. For the assembly of large wooden planes, it makes sense to construct a more complex clamp in the form of a system of two or more screws mounted on one station-based basis. Efforts invested in production technological instrument, always give proper returns when used.

Our instruction with a consistently described processing of joinery clamps of several varieties will be useful for novice lovers of woodworking. In it we will tell, what materials should be used for this and how to make a device, exactly suitable for your own needs.

Materials for hull, stop and sponges

In the joinery craft, the clamps use to reliably and carefully cut a few parts during their mechanical connection or while the glue dries. The pressing force should not be colossal, it is much more important not to damage the surface of the parts connected. At the same time, the clamp must maintain high strength and to be durable.

For the manufacture of clamp parts, directly in contact with the product being processed, it is better to use solid rock wood. Ideally, it is bars and planks from larch, beech, ram or birch. Such a tree has a sufficiently high strength and is characterized by elasticity, well restoring the form. The hardness of such wood is usually higher than that of the parts being processed, which can be compensated by knobs of leather, light rubber, felt or softer tree.

As a frame for clamp, you can use both solid wood and metal rolling. Corners or profile pipes well fit, but they need to be thoroughly cleaned, brew and paint, to ready product There were no traces of rust. To eliminate random mechanical damage or the jurisdiction of the parts connected, it is recommended over the metal elements of the clamp wooden planks Or stretch the dissolon silicone hose.

What to use screw and flywheel

Despite not a very high force of pressed, ordinary studs with metric thread Will not be very convenient for use as a clamp screw, unless very small. A small thread step will make a tedious selection of free move, among other things, the triangular profile "eats" is much faster.

Much more correctly will purchase studs with a threads of a trapezoidal or rectangular profile, otherwise called jack thread. The optimal step is about 2-2.5 turns on a centimeter, so good smooth adjustment is achieved and the optimal tightening force for wooden parts.

Get the hairpins, nuts and huts necessary type You can, or contacting directly to the turner, or in the store of hardware, including on the Internet. There is, however, one thing is: most factory products have a complete thread, while a slightly different screw configuration is optimal for clamp. Ideal if at the ends of the hairpin there are smooth wholes: a length of about 20 mm for planting the bearing (slightly thicker of the thread) and about 30-40 mm for the handle (slightly thinner or the same diameter).

Handle or flywheel can be made either from wooden barOr drove a hole in the hairpin on the side and inserting a steel bar into it as a cake lever as in the vice.

Direct screw clamp

For the manufacture of simplest clamp Rama is required in the form of a P-shaped bracket. It can be made in two ways. The first is to connect three bars in direct corners on the groove-thickened compound, strengthening it with glue and a pair of waders. This option requires a fairly high joiner's qualification: a chamber and fit to do with high accuracyFor the load in these nodes is very significant.

The second option is somewhat simpler, but more costly from the consumption of materials. Cut bracket can be made of thick birch plywood, gluing 3-4 blanks with a thickness of 12-16 mm glue for Titebond type.

When choosing the form of parts, consider that the most reliable will be a design with external hips for greater rigidity. The emphasis and the opposite part of it, in which the clamping screw will be fixed, should be a trapezoidal form. At the same time, inclined side should diverge the outside at an angle of about 30º more direct. Thickening in the middle part of the frame is also very desirable.

To secure the screw, it is recommended to use hollows or nuts of the corresponding diameter, which are fixed in one of the "horns" of the clamp frame from the inside and are additionally strengthened epoxy resin. If the bracket was going from bars, then you need to start a screw to one of them final assembly. If the frame design is multi-layered, then the hoods can be replaced with nuts that are pasted into the propyl central layer of plywood. It is important to keep track of the direction of the screw axis and at the same time not to enter glue in threaded connection - Lubricate it well with solidol.

In the place of attachment of the presser heel to the screw, some kind of swivel is needed, so that the parts do not shift. It is best to press the bearing, chosen by the diameter of the inner cable to the entire edge of the screw stud. To reliably stop the pin heel into the cartridge drill, and then a triangular file and a knuckle, cut the groove under the locking ring. Further in Bruke, an employee supporting heel, you need a crown drill to make a cylindrical groove and pinch the bearing with a heel, strengthening the landing of a varnish or epoxy resin.

Restored universal clamp

Clamps with variable width of the solution are more versatile in use, most often used when weakening furniture shields. For the manufacture of such a clamp, you will need a calibrated rail from dry wood solid wood, ideally from beech or ash. Permanent profile size is required along the entire length and the complete absence of any vices. From the thickness and width of the racks directly depends on the force of pressed, which clamp will be able to withstand.

So, the manufacture should be made from fixing at one end of the longitudinal rails perpendicular stop. It is better to make it from two bars, which are folded and clamping a rail in two symmetric grooves, or to fill the hammer to the manner. Thus, the workpiece under clamp with fixed focus acquires the T-shaped form, and the length of the stop from the working side should be more departure from the back side of no more than 3 times. The connection of the stop with the rail can be strengthened with furniture screeds, it is also possible to connect to 2-3 waders and PVA glue.

The opposite part of the stop is designed to consolidate the theater. For it, a straight steel bar with a diameter of 10-12 mm is perfect. At the end of the bar, you should cut the thread and spread it between the end stops with nuts from the inside. Holes under the tutor must be drilled as close as possible to the opposite edge of the stop. At the same time, the indentation from the edge should be sufficient so that the wood does not break. After installing the rig, it is necessary to place a plank on the end facing the clamping part, a series of notches in a step of 15-20 mm, to make a slot to 2 mm with a sucking knife and cut the knife to a knife on this markup.

Next, you should make a movable block of clamp. It is made through the through bridge of rectangular section, the dimensions of which are exactly the thickness and width of the longitudinal plank. Perfectly vouch the groove with dimensions by 2-3 mm less, and then bring it to necessary form Square rashpil. The bar should sit in the block tightly, but at the same time allowing the relatively free movement along the clamp and its tilt for the stopping on the scubs. Under the tutor, it is also necessary to do through a hole with the calculation so that the rod is located strictly perpendicular to the rail, and the block freely slides with a small backlash.

From the opposite side of the hard stop you need to fill another block, which will build a bar with a guy parallel to each other. To do this, you can use a small segment of the bar in which the chisel is made by the groove under the bar and the incomplete hole is drilled. For fixing the pads are used and bolts. As for the clamping screw and heel, they are installed by analogy with a conventional clamp. It is enough to drill the through hole in the movable block is not too close to the edge and glue it to a hood or a nut from the inside. So, when you press the part of the screw of the screw mechanism will rest in the wood and will sit even more tight.

Corner clamp

The most complex in the manufacture can be called a clamp that ensures the fixation of the two parts at right angles. At the same time, this is the most useful and in demand tool in the workshop of the carpenter.

The basis for corner clamps will serve a thick plywood segment. It is better to take a square rattle of about 300x300 mm with a thickness of at least 14 mm. In the corner of the base, you need to consolidate two vessels from the wood of solid rock, which for convenience are called reference. These pads must be converged at a right angle facing the center of plywood skull, the thickness of the bars is at least 25x25 mm. Their fastening should be as hard as possible: it is recommended to glue the bars first, ensuring their perpendicularity with a plumbing salt, and then strengthen the connection with screeds or bolts.

From the center of each bar, it is necessary to carry out a perpendicular line, coaxing with which screwed stiletts will be located. It is necessary to retreat from bars a distance of 20-30 mm more than the maximum thickness of tightened parts. After that, another two bar is mounted in parallel with the previous one. It is advisable to glue the nuts at once, and then proceed with stubborn bars as well as with references: first positioned on the adhesive connection, and then strengthen the screeds. For greater amenities, you can immediately screw the screwed stiletto in the nuts.

After fixing the stubborn bars, it remains only to press bearings, fixed in rolling pads. The cross section, the size and material of the latter should be similar to the reference bars. In completion, you need to fill the handles or insert a cake lever and crop excess the base of the clamp, removing the protruding angles for the free rotation of the knobs of the screws

Individual clamps for specific operations

In any carpentry workshop homemade clamps Show themselves more adapted to local working conditions, rather than purchased in the store. You can use a wide range of variations of the three designs described above.

For example, on one rail can not be fixed alone, but two stopping pads to position parts on a large distance. Such a tool will be very useful, for example, when assembling door blocks.

Instead of the handle, you can fight on the pin the usual hexagon cap from the bolt. This is relevant if, when assembling parts, several clamps must often clamp, release and rearrange. At the same time rotate the clamping screw will be convenient using forest head With a snoring mechanism or even screwdriver.

For assembling products complex form You can make stops of clamps and movable pads of a more complex configuration that are well suited to work with the details of the wrong shape.
