The invention relates to the processing of materials by cutting, namely, devices for securing parts, and is an improvement of the device according to the author. St. No. 1440659.

The purpose of the invention is to improve the reliability of fixing parts by sampling gaps between the clamping element and the part before fixing.

FIG. 1 shows the device with the pushing action of the clamping element; general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a view B in FIG. 2 (on wedge plates); in fig. 4 - clamping element, longitudinal section; in fig. 5 - hydraulic drive, general view with partial expansion.

The device consists of a clamping element 1, a hydraulic actuator 2 and an additional hydraulic actuator 3. The housing of the clamping element 1 consists of two coaxially mounted parts 4 and 5 that can move relative to each other, having working elements 6 and 7 on the lateral external surfaces A pin 8 is fixed to part 4 at one end, and the other end is located in a groove of part 5. A set of disc springs 9 is located in the housing of the clamping element 1. The hydraulic actuator 2 has a piston 10 which is pressed by the spring 11 from the cover 12 to the inner end of the core 13, in which a threaded bore 14 is made to connect to the hydraulic system. The hydraulic actuator 2 has one fixed 15 and one movable 16 fork arms, designed to interact with the projections 5 and 6 of the clamping element 1. Moreover, the lever 15 is fixedly mounted on the housing 13. And the lever 16 is hingedly connected to the piston 17 of the piston 10. The hydraulic actuator 2 is fixed on 18 hand industrial robot. The hydraulic actuator 3 consists of a piston 19, which is compressed by a spring 20 from the cover 21 to the inner end of the housing 22, in which a threaded bore 23 is made for connection to the hydraulic system and a hole 24 for extending the two shoulders of the levers of the rod 25. One end of the rod 25, made in the form of wedge, acts on the shoulders of the double shoulders levers 26 and 27, fixed on the axles 28 and 29, spring-loaded springs 30 and 31. At the opposite ends of the two shoulders levers 26 and 27 are fixed wedge plates 32 and 33, fixed by balls 34 and 35, which in their queue spring loaded Inami 36 and 37 and preloaded screws 38 and 39. Moreover, the inner end of the housing 22, the axis 28 and 29

mounted on the plate 40, which can be fixed on the arm 18 of the manipulator.

The device for securing parts works as follows.

Before fixing the part 41 to the fixture 42, the levers 15 and 16 of the hydraulic actuator 2 interact with the projections 6 and 7 on the clamping element 1. The hydraulic fluid 2 is fed through the hole 14 through the working fluid under pressure. The piston 10 of the hydraulic actuator 2, moving, acts on the levers 15 and 16, which, acting on the protrusions 6 and 7 of parts 4 and 5 of the clamping element 1, compress the cup springs 9.

After installation, the parts 41 supply the working fluid under pressure to the chamber of the hydraulic actuator 3 through the opening 23, the piston 19, moving together with the rod 25, acts on the two shoulders levers 26 and 27, superimposing the plates 32 and 33 on each other in the gap between the part 41 and the fixture 42 until it stops. Thereby, a clearance is made between the clamping elements 1 and the clamp. Then, the working pressure in the hydraulic actuator 2 is disconnected. The part 41 and the plates 32 and 33 are clamped, while the clamping force is provided by the energy of the set of compressed disc springs 9. Then the working pressure in the hydraulic actuator 3 is turned off. The piston 19 together with the rod 25 under the action of the spring 20 returns to the starting position. At the same time, under the action of the springs 30 and 31, the two shoulders levers 26 and 27 are dispersed, leaving the plates 32 and 33 pressed by the clamping element 1. The hydraulic actuator 2 together with the hydraulic actuator 3 is retracted.

The loosening of the part 41 is carried out in reverse order.
