Abstract

The invention relates to the processing of materials by cutting, namely, devices for securing parts to machine tools and improves productivity by reducing the time for securing and detaching parts. The tool 19 accommodates the part 18 and the clamping element 1 with the working elements 5 and 6, which can be made in the form of protrusions or in the form of nest walls. A hydraulic actuator 2 with two forked levers 14 and 15 is fixed on the arm 17 of an industrial robot. The forked lever 14 is fixed on the hydraulic actuator 2, the forked lever 15 is hinge mounted on it and is connected pivotally to the hydraulic actuator rod 2. Before installing the part 18 in the device 19, the forked levers 14, 15 of the hydraulic actuator 2, by means of the arm 17 of the industrial robot, compress the movable parts by their projections or the walls of the sockets 5 and 6 of the clamping element 1. After installation of the part 18, the clamping element 1 secures the part 18 under the action of a set of disk springs. 3 h. . f-ly, 8 ill. (ABOUT

The invention relates to the processing of materials by cutting, in particular, to devices for securing parts to machine tools.

The purpose of the invention is to reduce the time for fixing and detaching parts.

FIG. 1 shows the device with the pushing action of the clamping element; general view; in fig. 2 - the device, a section of a clamping element; in fig. 3 - hydraulic actuator mounted on the arm of an industrial robot, general view; in fig. 4 shows the device with the tightening action of the clamping element, general view; in fig. 5 is a view A of FIG. 2 (when the work items in the form of protrusions); in fig. 6 is a view B in FIG. 3; in fig. 7 — node I in FIG. 5 (when working elements in the form of nest walls); in fig. 8 is a view of B in FIG. 7

The device consists of a clamping element 1 and a hydraulic actuator 2. The case of the clamping element 1 consists of two coaxially mounted parts 3 and 4 that are movable relative to each other, having working elements-projections or slots 5 and 6 on the side outer surfaces. On part 3 at one end, the bolt 7 is fixed, and the other end is located in the groove of the other part 4. A set of disc springs 8 is located in the housing of the clamping element 1. The hydraulic actuator 2 has a piston 9 that is pressed by the spring 10 from the lid 11 to the inner end of the housing 12, in which A threaded bore 13 is provided for connection to a hydraulic system. The hydraulic actuator 2 has a pair of forked arms 14 and 15 that are movable relative to each other and are designed to interact with the projections or slots 5 and 6 of the clamping element 1. At the same time, the lever 14 is fixedly mounted on the housing 12, and the lever 15 is pivotally connected to the shaft 16. The hydraulic actuator 2 can be mounted on the arm 17 of an industrial robot. Part 18 is anchored in adaptive assembly 19.

When using the device for securing the parts 18 as a pulling clamping device, the clamping element 1 comprises a stand 20, abutting one end against the part 4 of the body of the clamping element 1, and the other end connected with the fixture 19, while part 3 of the case of the clamping element 1 resting in tack 21.

A device for securing parts when used as a pushing clamping device works as follows.

Before fixing the part 18 in the fixture 19, the levers 14 and 15 of the hydraulic actuator 2 are inserted before interacting with the projections or with the walls of the sockets 5 and 6 on the clamping element 1. The hydraulic fluid is fed through the hole 13 through the opening 13. The levers 14 and 15, acting on the protrusions or walls of the sockets 5 and 6 of parts 3 and 4 of the clamping element 1, compress the disc springs 8. In a compressed state, the clamping element is installed in the fixture 19, while the hydraulic actuator 2 is connected to the clamping element 1. After the installation of the parts 18, the working pressure in the hydraulic actuator 2 is shut off. The disc springs 8 of the clamping element 1 are unclenched, their force is transmitted to the device 19 and the part 18,

f. item 18 is fixed. The hydraulic actuator 2 is retracted. The loosening of part 18 is carried out in reverse order.

The operation of the clamping element 1 together with the hydraulic actuator m 2, when using the device for securing the parts 18 as a pull clamping device, occurs in the same way as when used as a pushing clamping device. Only in this case, the force of the disc springs 8 is transmitted to the rack 20 associated with the device 19, and the clamp 21, which in turn transmits the force to the component 18, thereby pressing the part to the device.
