Description

one

The invention relates to the processing of materials by cutting, namely to the elements of the device for securing parts of complex configuration on machine tools.

The aim of the invention is to increase labor productivity by reducing the time to retool the device. FIG. 1 shows a device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 shows a section B-B in FIG. 2

The supply support includes a base I, on which clamps 2 are installed, the base supports 3 and the support 4 are supplied, holding the case 5, in the upper and lower parts of which are made the rectangular main 6 and additional 7 cavities connected by holes 8. The main the cavity 6 is enclosed by a hermetic elastic sheath 9 attached to the body by means of a lining 10, in which holes 11 are made, covered with an air-permeable plate 12, for example of felt. The cavity 6 enclosed by the shell 9 is filled with a loose mass 13, for example quartz sand, while on two longitudinal sides of the shell 9 are the strips 14 connected to the plungers 15 installed in the openings 16 of the housing 5 so as to move from the springs 17. The cavity 7 is closed by a lid 18 with a fitting 19 attached to it to be connected to the compressed air line 20 and divided by an overpressure spring 21 by a piston 22 sealed by an elastic diaphragm 23 into an air 24 and a vacuum 25 chambers, which ohm channels 26 and 27 and

valve 28 is capable of being connected to the atmosphere.

The support works as follows. In the initial position, the part 29 is absent, from the action of springs 17 and strips 14 5 on the lateral sides of the shell 9 and through it on the bulk mass 13 the surface of the shell 9 is expanded and occupies position a, the valve 28 is open, as a result of which the vacuum chamber 25 is channels 26 and 27 0 communicates with the atmosphere, with the springs 21 the piston 22 is pressed against the lid 18, and the chamber 24 via controls (not shown) communicates with the atmosphere.

On the base supports 3 install the part 29. And secured with the clamps 2.

5 With the force of the clamps 2, the part 29 acts through the shell 9 on the bulk weight 13. The slats 14, the plungers 15 and the springs 17, which then settle, force the shell 9 to lie down tightly against the surface of the part 29 and take position b. The air from the cavity 6 is forced into the atmosphere through the air-permeable plate 12, the holes And and 8, the chamber 25 and the channels 26, 27. The chamber 24 is supplied with compressed air, which, compressing the springs 21,

5 lifts the pistol 22, displacing the air from chamber 25 through channels 26 and 27. Then the valve 28 is closed, isolating the vacuum chamber 25 from the atmosphere, and from chamber 24 air is released into the atmosphere. From the force of the springs 21

0 22 is pressed to its original position, with the result that in the chamber 25 and connected with. A cavity 6 forms a vacuum, and by overpressure of the atmosphere on the shell 9, the bulk mass 13 is compressed from all sides and thereby fixes itself and fixes the part 29 in the set position, after which the part z9 is processed.

After processing, the clamps 2 undo and remove the part 29, while the dry mass 13 retains the shape given to it by the shell 9 and can be used to install another part 29 if the shape of its surface matches the shell sufficiently accurately. 9. When machining a part 29 with a different surface shape, the bulk mass 13 and the shell 9 are returned to their original position by opening the valve 28, atmospheric
