The invention relates to the field of cutting materials, namely, devices for securing parts to machine tools.

The purpose of the invention is to simplify the design.

FIG. 1 shows the device in the position of clamping and fixing parts, the full view; in fig. 2 shows section A-A in FIG. I; in fig. 3 shows a section BB in FIG. one; in fig. 4 - the same, in the position of dilution of self-depleting elements with them; in fig. 5 is the same in the wedging position of the self-aligning elements; in fig. 6 is a sectional view BB in FIG. 3; in fig. 7 - the device in the position of unclamping the workpiece and retracting self-installing elements from the zone of loading and unloading parts; in fig. 9 is a section d-d in fig. 3, when performing self-installation; their elements in the form of prisms; in fig. 10 - the same, with self-aligning elements, spring-loaded against each other with the help of springs of the first half ring; in fig. 1 1 - section EE of FIG. 9.

The device for fixing the parts is co-located with the o-ring - the square 1, on which the base elements 2 and the hydraulic cylinder 3 are arranged, the rod 4 of which is connected with the rod 6 by means of axis 5, the contact with the roller 7 disposed in the bracket 8, a rigidly mounted pa square 1.

A rolling pin 9, which is made up of two strips 10 and 11, rigidly connected with the latter, has a lever 12, is placed in step 6. Between the strips 10 and 11 on the axes 13, the self-adjusting pressure rings 14 with the pushrods fixed on them 15 with shoulders And, on which spring-loaded springs are installed with axially 1st displacement, 16 taken out in p; ide glasses of jnyca 17. In cases 17, spring-loaded spring 18 is placed with respect to the caps 19 1ko associated with Cornuses 17 self-aligning elements 20 with screws 21 placed in 1, contacting them with the separation of elements with clip bevels, E, full pushers 15. In self-aligning elements 20, grooves are made through which pushers 15 pass, on which Rings 22 are rigidly installed; They come in contact with samoustanavlivayuschiemi-with element 20 and 20 when it is jammed. From pivoting the housings 17 relative to the pushers 15, the pins 23 are mounted in the housings 17, which are included in the grooves made on the pushers 15.

The ca. mounting elements 20 are designed to be made in the form of prisms 24 installed in housings 17 with the possibility of displacement and rotation around an axis, parallel to the front face of the prism 24 (axes of the pushers 15) and the springs are spring 25 each

relative to a friend. The device is intended for clamping and fixing parts 26.

The device works as follows.

In the initial position, the working fluid is fed into the piston cavity of the hydraulic cylinder 3, while the rod 4 is in the extreme right position. A ha 6 with a lever 12 and self-adjusting pressure rings 14 is folded back. In this position, the housings 17 are pulled by springs 16 to the shoulders And pushers 15. The screws 21 of the self-aligning elements 20 are in contact with the surfaces of the pushers 15, and their separation.

The workpiece 26 is loaded, then the working fluid is supplied to the rod of the hydraulic cylinder 3, the rod 4 is moved to the left.

T ha 6, connected with stem 4, in contact with roller 7, lifts lever 12 with self-adjusting pressure rings 14, pushers 15, housings 17 and brings the ends of housings 17 to the ends of the machined parts 26 with spring 16 force. The rod 4, moving further to the left, moves the lever 12 with self-adjusting clamping rings 14 and pushing 1 15, compressing the spring 16, the screws 21 coming out of contact with the wedge bevels of the pushers 15, and under the action of springs 18 self-aligning elements 20 fit the workpiece 26.

The rod 4 of the hydraulic cylinder 3 is moved until the rings 22 of the pushers 15 touch the self-aligning elements 20, jamming the latter and finally clamping the workpieces 26 with the corns.

When the working fluid is delivered into the piston cavity of the hydraulic cylinder 3, the rod 4 moves to the right with the lever 6, the lever 12, the self-adjusting rings 14 and the pushers 15, while the housings 17, which are spring-loaded by the springs 16, remain in place, the rings 22 of the pushrods 15 split the self-aligning elements 20. Continuing to move to the right, the pushers 15 move relative to the screws 2 of the self-aligning elements 20 in contact with the wedge bevels of the pushers 15, the divorce of the self-aligning elements 20. Then the pushers 15 capture with the ends of the housing 17 and further, they already move together with the housings 17 until the rod 4 reaches the extreme right position, while the pull 6 is with the lever 12 self-adjusting the rings 14, the pushers 15 and the housings 17 fold back.
