Abstract

The invention relates to mechanical engineering, in particular to auxiliary equipment for securing products during processing. The aim of the invention is the expansion of technological capabilities by ensuring the movement of the clamping lever in a limited working space and improving the reliability of the clamp. After installation of the product 13 into the working position, the pusher 5, moving in the opening of the rotary support 3, acts through the guide element 7 on the walls of the screw openings of the rotary support. The grip rotates, but does not move in the axial direction, since it is fixed secured in the housing 1 of the bolt 10, placed in the annular groove of the sticking. The turning of the sticking stops when the guide element 7 falls on the straight section of the helical groove. With further movement of the wheel 5, its end rests on the end of the two-shoulder hold-down lever 12, which, turning on the axis, fixes the product. The lever is returned by the spring 14, and the magnitude of its working stroke is adjusted by the stop 15. This design of the device allows it in a limited working space due to a slight retraction of the pressure lever in the plane, passing through the axis of the pusher, and then turning it. The implementation of the clamping lever of the two shoulders helps to increase the effort and increases the reliability of the clamp. 2 Il. I (L 4 O CO 00

Description

The invention relates to mechanical engineering, in particular to an auxiliary. equipment for securing products during processing, and can be used for clamping products in welding machines and machine tools.

The purpose of the invention is the expansion of technological capabilities by ensuring the movement of the clamping lever in a limited workplace is simple; lacTB and higher reliability Ppsg

Figure 1 shows a clamping device, a longitudinal section; FIG. 2 is a section A-A in FIG. i,

The device includes a housing 1 with a hole, 2, in which a rotary tack 3 with an L-shaped head A is located, as well as a pusher 5 located in the opening 6 of the sticking tongue 3. The pusher 5 is provided with a direction element 7, made in the form of a pin. The guide element 7 is placed in the screw grooves 8 of the clamp 3 and in the straight grooves 9 of the housing 1. In the housing 1, a tongue 10 is installed, the end of which is located in the annular groove 11 of the stuck 3. On the L-shaped head 4 of the stuck 3 there is a hinge on the axes of the two shoulders presser lever 12 for the product 13. The two shoulders presser lever 12 is spring-loaded relative to the sticking of the spring 14 and provided with a stop 15, made in the form of a screw (power supply not shown).

The clamping device works as follows.

In the initial position of the swivel, the clamp 3 with two shoulders clamping lever 12 is rotated to the desired angle relative to the product 13. This angle. is determined by the parameters of the screw grooves 8. The pusher 5 is in the extreme left position together with the guide element 7. Due to the fact that the guide element. 7 with their ends is placed in the straight grooves 9 of the housing-1, the pusher 5 has the possibility of only reciprocating movement, and, turning the hook 3 can only make a turning movement, since the pin 10 prevents it from moving longitudinally. the lever 12 under the action of the spring

4 preloaded through the limiter 15 to the tack 3.

After the product 13 is placed in the desired position, the plunger 5, moving in the aperture 6 of the grip 3, acts through the guide element 7 on the walls of the screw grooves 8, whereby the clamp is turned in the opposite direction to the screw grooves. The rotation stops when the guide member hits the straight part at the end of the helical groove. Upon further movement of the pusher 5, the end of the latter rests on the end of the two shoulders presser lever 12, which, turning on the axis, secures the workpiece 13. The working stroke of the two shoulders presser lever 12 is adjusted using the stopper 15.

Due to the proposed construction of the device, the clamping lever is moved at a time; the kim is carried out in a limited working space, and the implementation of the clamping lever two shoulders increases the reliability of the clamp; MA by increasing the clamping force compared with the known device, j
