2. The device according to claim 1, l and t are longitudinal corrugations, and between the end walls, in that the walls: with the surfaces of the tape and the matching housings, mated with flat surfaces of the body with them tapes are made with sealing seals inserted.

t

The invention relates to mechanical engineering and can be used to secure products when performing targeted operations.

The purpose of the invention is to reduce the metal consumption of moving parts and reduce the size of the device.

FIG. 1 shows the proposed device, a general view in section in FIG. 2 is a section A-A in FIG. one.

The device consists of a plunger 2 placed in the housing 1 and interacting with a wedge element 3 fixed on the tape 4 mounted on the guides 5. The ends of the tape 4 are bent and fixed 1 Fixed on the housing 1, with the walls 6 and the arcuate partitions 6 of chamber 7 and 8 for supplying the working medium. The plunger 2 is kinematically connected by a spring-loaded tack 9, hinged on the rack 10.

In order to reduce friction between the planes of the belt 4 and the surfaces of the body 1 that mate with them, on the latter, longitudinal corrugations 1 are made, and for sealing

chambers 7 and 8 between the ends of the tape 4 and the walls of the housing 1 installed sealing strip 12.

The device works as follows.

The fixed product 13 is placed on the supporting surface 14, and a tack 9 is brought to its surface. Then the working medium is supplied under pressure to the chamber 8, which causes the movement of the tape 4 and the wedge element 3 connected with it, which acts on the plunger 2. the axial movement of which is transformed by grip 9 in the sum of the clamping of the product 13.

In order to retract the tack 9 from the workpiece 13, the working medium is supplied to the chamber 7.

The application of the proposed device allows reducing the metal capacity of the clamping devices and expanding their technological capabilities by reducing the size, which ensures the use of clamping devices in hard-to-reach and limited areas.
