Table and drill bit attachment

Drill Stand Machine (drill stand) is used in the conditions of production or workshop, when it is necessary to make a number of holes in workpieces with maximum accuracy. The drill can be clamped securely and centred quickly in materials of all hardness.

The drill stand consists of the following components.

  • The support base is attached to the table, for this purpose there are holes for screws.
  • The cylindrical vertical stand is mounted perpendicular to the base and the drill moves down/up on it.
  • Sliding bracket mounted on the stand, has a clamping flange for securing the drill.
  • The drive lever is needed to raise/lower the arm with the tool.

Depth limiter and workpiece clamping vise can be additionally installed in the construction of the stand. Most models do not require plugging into a socket, but magnetic drill presses are powered by electricity.

Retaining force of the magnet can reach 25 kN, which ensures reliable fixation of the tool and excludes appearance of backlashes when it moves on the stand.

Features of the drill stand application

With its help one can easily turn a usual drill into a drilling machine and achieve the quality of material processing, that approaches to the factory one. Using the stand-machine, you can ensure a smooth stroke of the drill strictly in a straight line. Reliable fixation of the tool prevents its displacement relative to the axis of motion, making the holes produced in the material accurate and precise.

The drill is positioned on the bracket so that the drill bit is pointing down strictly perpendicular. the tool is plugged in, the workpiece is placed on the worktable. the place of the future hole must be under the drill. After locking the start button on the drill, you can start drilling. To do this, you must use the lever to move it down, after making the hole. up.

The work on the drill rig differs from manual drilling in that the workpiece is moved relative to the tool, not vice versa. The operator gets less fatigue, achieves higher drilling accuracy and saves time during drilling.

What parameters to choose from?

Diameter of the clamping flange. This parameter affects the size of the drill, which can be fixed on the stand. Different models have different values, e.g. 43 mm or 65 mm, etc.ะด. As a rule, each machine is designed to work with the tool of a certain modification of a particular manufacturer.

Working length. Its value depends on the height of the stand and determines the stroke of the tool. The longer the length, the higher the drill can be raised, and therefore, the larger workpieces can be placed on the workbench. This parameter is usually 200. 300 mm. But there are models with working length up to 500 mm. Such drill stand has a higher price than models with standard size.

Making a stand for the power tool

One such plate will not be enough, as it is too light, so we saw another one. We put it on top and draw it on the contour with a marker.

We need two more clamps like this. They’re used to fasten pipes, there’s plenty of them in construction stores in every diameter.

Rubber pads will not create excessive force on the tool body and will not let it move anywhere. Now you can work.

All examples are in your face. The stand is very simple and very comfortable. With a little vibration, it won’t tip over.Also it is necessary to tighten the trigger or switch of the tool with a plastic tie or other way before the work. Be extremely vigilant when working with the tool in this position. I recommend to make a foot pedal-button, so that when you press it with your foot the tool will turn on.

Drilling machine drives

Making the project of assembling the holder for a drill with your own hands, it is necessary to determine the type of the lifting and releasing mechanism, which serves for vertical delivery of the drill to the workpiece. It is the main characteristic of the machine. The following mechanisms are distinguished:

Spring, spring hinged and hinged units are the easiest to assemble by your own hands. The drawings of the drilling machine from the spring-type drill suggest placing the spring either directly at the handle or at the base of the carriage in special slots. In the absence of additional locks, it will be impossible to mill with such machines, as they require constant manual control of the drill position.

Devices based on toothed rack and “star” (gear wheel, car bendix) must also provide additional locks. They can be made, for example, by placing an additional screw on the drill mount, working on the principle of a friction. When the cutter has reached the required position, the screw on the guide is tightened and you can then proceed to chamfering and grooving.

Screw-type mechanisms work on the same principle as jacks. At their base is a vertically positioned tube with a thread, allowing rotation around its axis. On the tube there is a nut welded to the drill holder. As the tube rotates, the nut and tool mount changes its position. For additional stability of the tool during operation, it is allowed to equip the mountings with a friction.

Materials:

The column of the machine is a plywood base on which the linear guides with bearings will be mounted. It is cut 20-30 cm longer than the guides. On the reverse side it must be reinforced with stiffeners.

It is necessary to screw it to the base on an oblique screw. Two blind holes are made in the table for linear guides. At the upper point, they are fastened to two plywood strips, also screwed to the base. The guides are glued into the seating holes with epoxy glue. Linear bearings are put on them before. It is imperative that the right angles are kept.

To strengthen the table, it is necessary to cut 2 side inserts from plywood and screw them from below. They are connected to the bottom of the frame and the table with a slanting screw. You will need to make holes in the sides with a large router. Under the table a turnbuckle is screwed to the bed.

An adjusting wheel is made from a plywood disc. In it, 3 holes are drilled in the side, and bolts from the anchors are glued into them. The wheel is then drilled in the center and the shaft is glued into it. At the place of gluing, notches are cut on the shaft. A mark is made on the side of the wheel. To do this, simply glue a nail and cut it flush.

It is a piece of plywood with a hole equal to the diameter of the body of the drill at the place of installation of the removable handle. The piece is cut to the hole and fitted with a bolt and nut. This way, when they are tightened, the inserted door will be clamped.Also from plywood cut a shield to mount the drill. It is screwed to the linear bearings on the rails. The previously made clamp is attached to it with an oblique screw. Install two stiffeners underneath.

On the back of the shield timber blocks with pressed bearings are bolted on, in which the shaft with the adjusting wheel is placed. The shaft is secured around the edges with plywood disks.

To operate the hoist, a wire is required between the turnbuckle under the table and the upper rail mount. It must be wrapped around the shaft several times. Then it is tensioned with the turnbuckle.

To reduce runout, it is necessary to make a cage for shaft limiters. They are plywood blanks cut in half, left over after drilling out the limiters. The clamps are bolted to the bed.

Making a steel lathe: instructions with step-by-step photos

Metal machine consists of similar nodes, but it is more difficult to make them because of the complexity of processing the material. The advantage of the construction is in reliability and absence of backlash, which is ideal for installing additional units that expand the functionality of the machine.

The general structure of the metal machine is shown in the drawing, and the order of construction is as follows:

  • Stand welded from a square or round tube with a cross section of 32-40 mm. You can weld a sleeve with a larger diameter on the plate, and insert the pipe and clamp it with a bolt.

Now all that’s left is to put all the nodes into one structure and try to clamp the drill.

Required materials:

Mark and fix on the bar 90×45 movable elements of ball bearing guides.The length of the bar should correspond to the length of the guides (in my case. it is 30 cm).

For the uprights we will use a bar with the same cross section. we will need two pieces of 70 cm each. On the uprights we will fix the counterparts of the rails with wood screws.

To the lower ends of the uprights we fix a base made of plywood with dimensions of 290×500 mm. For stiffness on the back side of the future drill press we attach a bar 50×50 mm.

Check the perpendicularity of the base and the uprights with a square.Do not ignore this step. The more accurate you are at each step of the assembly, the easier it will be to adjust the perpendicularity of the drill axis to the base at the last step. 6. Strengthen the upper part of the frame with the 10 mm plywood plate, size. 90×204 mm.

To fix the drill on the slide, I used an old crank I found from another drill (you can use the regular crank if you don’t use it).Mark out the contour. ) We saw off the excess (it won’t affect the rigidity and will only interfere with the work). Make a hole for the drill with a few millimeters more in diameter than the hole in the handle.

For fixation of the slide in an up position we use springs. with the help of two hooks and two springs we get reliable return of the slider to its initial state even with a heavy drill.

If necessary, adjust the angle of fixing the elements of the slider to each other.12. Make a movable table with the possibility of adjusting the height of the table.The necessary materials for the table:

For mounting, I used the fasteners, which were at hand. bolts M6, M10, sanitary rod M8, washers and nuts to them.

Features

Multifunctional stand for the drill, which allows you to perform various works, usually consists of certain components. First, you need the supporting frame. it is on it that all the elements will be fixed. Secondly, there must be a stand. a guide for the drill, used to fix it. This element allows you to move the drill itself using the handle and other elements. Thirdly, the above-mentioned handle is important, coordinating the vertical movement of the drilling part. Finally, there are additional assemblies, with the creation of which the machine is even more functional.

The size of the bed depends on the direction of work to be performed with the device.

For example, when performing only vertical drilling, a sheet with sides of 500 millimeters is sufficient. If much more complex operations are expected, the length should be increased to 1000 millimeters, and the width should remain the same. On the bed vertically placed rack, which is fixed by a special support. The two parts are frequently joined together by screws.

The mechanism for moving the drill in the vertical direction

Homemade machine for drilling must be equipped with a mechanism that will ensure the movement of the drill in the vertical direction. The structural elements of such a unit are:

  • handle, by which the carriage with the drill attached to it is brought to the surface of the workpiece;
  • The spring needed to return the drill carriage to its original position.

It is possible to make such a mechanism using two constructive schemes:

According to the first variant, the construction is carried out according to the following scheme:

  • on the stand of the machine with the help of screws two metal plates are fixed, between which the axle is installed, where the handle of the machine will be located;
  • On the other side of the stand also set the plates and the axis, on which fix one end of the spring, and its second end is connected to the handle;
  • the pin, by means of which the handle is connected to the carriage of the machine, is placed in a longitudinal groove, made in it.

The basis was an old stand from a photo enlarger “Krokus” made in Poland

If the springs are in the lower part of the return mechanism, then the handle of the device is also fixed by means of two plates and an axle that ensures its movement. In this design scheme springs are located in the lower part of the guide grooves, which are finalized with the help of metal angle bars that limit their movement.

The principle of a drilling machine with springs at the bottom of the carriage is quite simple: As it descends during drilling, the carriage with the drill attached to it compresses the springs; when the mechanical action of the springs stops, they open, raising the carriage and the drill back to their original position.
