Description

The invention relates to a machine tool industry, in particular to clamping devices of machine tools.

The purpose of the invention is to expand {technological capabilities by reducing the dimensions of the elements of the clamping device located above the surface of the table.

FIG. 1 shows the device, a general view; in fig. 2 - the same, axial section.

The device for securing the part comprises a cup 1 with protrusions 2 designed to interact with T-shaped grooves 3, made on the drive element of the hydraulic actuator 4 mounted coaxially with the force element. The power element contains a package of disc springs 5, worn on the sleeve 6 connected to the cup 1. The package of disc springs 5 with the sleeve 6 can be installed in the cavity of the machine table, while the package of disc springs is supported by one end in the sleeve of the sleeve 6, and the other in the bottom of the cavity table machine. At the end of the glass 1, on the side opposite to the installed sleeve 6, there are flanges 7 and protrusions 2. A clamping strip 8 is installed between the shoulders and is designed as a fork, one end resting on support 9, and the other end presses the workpiece 10 to the table surface

a package of disc springs 5, with the help of which the part 10 is fastened. To fasten the part to the power unit, install the hydraulic actuator 4 and connect them by inserting the projections 2 of the cup 1 into the T-shaped grooves 3 of the lower part 13 of the hydraulic actuator and turning them until the projections enter the extended part of the grooves. In the cavity of the hydraulic actuator 4 through the hole 17 serves under the pressure of the working fluid. In this case, the piston rod 14 rests on the post 12, and the hydraulic actuator housing 4 lifts the glass 1, thereby compressing the disc springs 5 and releasing the clamping bar 8. The rail 8 rotates or moves away from the part 10. Thereafter, the working fluid switches to drain, the disc springs 5 unclenched and hydraulic actuator 4 removed. Thus free up the strap 8 on all power units. After replacing the part 10, the installation process of the hydraulic drive 4 and its removal are repeated in the same sequence, and the strips 8 are mounted on the part 10. Thus, the part 10 is fixed. Multiple devices can be serviced by a single hydraulic drive.

Claims (2)

Claim 1. Device for securing parts on the machine table, containing machine tool. On the outer surface of the glass is a glass with protrusions designed 0 five 0 five 0 a package of disc springs 5, with the help of which the part 10 is fastened. To fasten the part to the power unit, install the hydraulic actuator 4 and connect them by inserting the projections 2 of the cup 1 into the T-shaped grooves 3 of the lower part 13 of the hydraulic actuator and turning them until the projections enter the extended part of the grooves. In the cavity of the hydraulic actuator 4 through the hole 17 serves under the pressure of the working fluid. In this case, the piston rod 14 rests on the post 12, and the hydraulic actuator housing 4 lifts the glass 1, thereby compressing the disc springs 5 and releasing the clamping bar 8. The rail 8 rotates or moves away from the part 10. Thereafter, the working fluid switches to drain, the disc springs 5 unclenched and hydraulic actuator 4 removed. Thus free up the strap 8 on all power units. After replacing the part 10, the installation process of the hydraulic drive 4 and its removal are repeated in the same sequence, and the strips 8 are mounted on the part 10. Thus, the part 10 is fixed. Multiple devices can be serviced by a single hydraulic drive. Claim 1. Device for securing parts on the machine table, containing  glass with protrusions designed On 1 fulfilled 11 turnkey flats. Inside the cup 1, a stand 12 is positioned, resting in the bottom of the cavity of the table from the tank. The power unit is connected to the hydraulic actuator 4 by means of protrusions 2 cups 1 and T-shaped grooves 3, made on the lower part 13 of the hydraulic actuator housing 4. The piston 14 of the hydraulic actuator 4 is preloaded by a spring 15 located between the piston 14 and the end of the upper part 16 of the hydraulic actuator housing 4, having a threaded hole 17 for connecting to the hydraulic system. The device works as follows. The power elements are mounted in a specially made cavity-machine tool. On the table is set. the workpiece 10. The sleeve 1 is screwed into the sleeve 6. Then the support 9 and the strip 8 are installed, and the sleeve 1 is screwed in until it is compressed 0 five 0 five for engaging with T-shaped grooves made on the drive element of the hydraulic actuator, the casing of which is placed coaxially with the force element, made in the form of a package of cup springs, the clamping element and the stand designed to interact with the hydraulic actuator rod, characterized in that . by reducing the dimensions of the clamping device elements located above the table surface, the device is equipped with a sleeve with a flange mounted on a glass on which flanges are made, and a package of spring-loaded springs is mounted on the sleeve with the possibility of one end interacting with the flange of the latter; to place a clamping element between them, and the spring package hub is intended to be placed in the machine table, with the second end of the package of spring-loaded springs set en with the ability to interact with the bottom of the cavity, made in the table of the machine.
