Abstract

The invention relates to the processing of materials by cutting, in particular, to devices for securing parts to machine tools. The invention improves labor productivity by reducing the time to install parts. In the support post 1 with a movable box-shaped holder 2 and a clamp 3 there are made the front row 4 holes for mounting the movable support pin 5 and the rear row 6 holes for installing the additional movable support pin 7 with flats. The base of the stand 1 is made in the form of a T-shaped protrusion 8 that fits into the groove of the hook 9. In the side walls of the yoke 2 there are elongated windows for accommodating the pin 5, supporting platforms 13 for supporting it on the pin 7 and through horizontal grooves for setting the clamp 3. The catch 9 is inserted into the groove of the plate, the protrusion 8 of the stand 1 enters the T-shaped groove. The clamp 2 with the clamp 3 and the fifth 16 is lowered until it contacts the part 10. Then the pin 7 is inserted into the nearest hole of row 6 by moving the screw 15 a contact of the platform 13 with the pin 7 is provided, and e On further movement - fastening component 10. 5-yl.

of the portable sliding support pin 7 with flats. The base of the pillar 1 is made in the form of a T-shaped protrusion 8 that fits into the groove of the hook 9. With the side walls of the casing 2 there are elongated windows for dismounting the pin 5, supporting platforms 13 for supporting it on the pin 7 and through horizontal grooves for setting the clamp 3 The grip of the hook 9 is set to

the groove of the plate J into the T-shaped groove of which B1 enters: stupa 8 of rack 1. The clip 2 with the clamp 3 and the fifth 16 is lowered until it comes into contact with the part 10. Then the pin 7 is inserted into the nearest hole of row 6 6. Moving the screw 15 provides contact pads 13 with a pin 7, and its further movement - fixing parts 10. 5 Il.

The invention relates to the processing of materials by cutting, in particular, to devices for securing parts to meta-processing machines.

The purpose of the invention is to increase productivity by reducing the time to install parts.

Figure 1 shows the universal tack, a general view; figure 2 - resolution A-L on fg.1; on fig.Z - universal sticking without retractable holder, general view; figure 4 - section bb in fig.Z; Fig. 5 shows a variant of fixing a part with the help of universal clamps on a square.

The universal tack for fastening the parts includes a support post 1, on which a movable holder 2 of a box-shaped form is mounted, carrying a mobile clamp 3.

The rack 1 is provided with two vertical rows of holes — the front row 4 for installing the mobile support pin 5 and the rear row 6 for installing the additional mobile support pin 7 with flats. The base of the rack 1 is made in the form of a T-shaped protrusion 8 that goes into the hook groove 9, which, in turn, enters its T-shaped protrusion into the groove of the plate on which the workpiece 10 is installed.

Lower platform T-shaped protrusion 8 extended and provided with a support sole 11.

The movable sleeve 2 is box-shaped, providing coverage of the rack with small gaps, allowing free movement of the holder vertically. In the side walls of the yoke 2 there are elongated windows 12, which coincide with a vertical row of 4 holes, in one of which

A pin 5 is installed. On the lower horizontal faces of the side walls of the casing 2, supporting platforms 13 are provided for supporting the pin 7 inserted into one of the holes of the rear additional vertical row 6. In the upper part of the casing 2 there are made through horizontal grooves for mounting the mobile clamp 3 made in the form of parallel strips connected by a part 14 with a threaded hole. A screw 15 is installed in this hole, connected to the hinge pin 16. The screw stroke 15 corresponds to the vertical step between the holes of the rack 1 in each of rows 4 and 6. At the same time, the distance between the said holes is chosen in such a way in order to press the pin 3, it can be placed between the pins 3 and 7 directly on the rack 1 to fasten the parts 10 (FIG. 3 and 4) to a ledge of small height. Squares 17 can be used to fasten the parts 10.

The fixing of the parts is carried out as follows.

Next to the part 10 fixed on the machine plate, a hook 9 is placed in the nearest plate groove, into which stand 1 is inserted into its T-shaped protrusion 8. The sleeve 2 together with clamp 3 is lowered until the contact 16 contacts the surface of the part 10. Then under the bottom of the clip 2 in

pin 7 is inserted near the rear row 6 hole. Thereafter, the adjustment of the adjusting screw 15 corrects the position of the yoke 2 relative to the stand so that the platform 13 rests on the flats of the support pin 7, and the lower section of the elongated window 12 is set slightly below the nearest hole of the row 4 The pin is installed in this hole.

Due to the presence of an elongated window, hitting the pin 5 into the desired hole without causing difficulties. Now, turning the screw 15 tightens the clamping device until all the gaps are selected, after which the final clamping of the part 10 is performed.

If it is necessary to clamp the part 10 over a small protrusion, the installation of the clamp 3 is carried out without the movable casing 2 (Fig. 3 and 4). In this case, after the clamping of the pin 16 is supported on the part 10, the support pin 7 is placed under the lower face of the clamp 3, and the pin 5 is placed above its upper face. Then, the adjustment and clamping is performed in the same way as when using the slide holder 2 I

When using a device for clamping parts on longitudinally milling machines and similar machines, as well as on the vertical wall of the square, the height of the stand 1 is selected taking into account the allowable elevation of the device above the part 10 of the minimum height.

When fastened on the square 17, the tack is inserted into the previously inserted hooks 9. In this case, it is advisable to pre-tune to the desired height. After installation in the hook 9, it remains to choose the backlash by rotating pery j of the leveling screws 15 and
