Abstract

The invention relates to metalworking and can be used to secure products. The purpose of the invention is to increase the reliability of fastening by introducing additional clamping. In the base 1 there is a drive element made in the form of a screw 2 mounted in a threaded hole of the slide 4, made in the upper part with a bevel δ for interacting with the spring-loaded spring 7 of the plunger 6. On the axis 9 in the base 1 there is a swinging lever 8 designed to interact with screw 2. After installing the product, turning screw 2 moves slider 4 and lever 8. Slider 4 slant δ moves plunger 6, which secures the product relative to base element R of base 1. Simultaneously, the movement chaga 8, which produces additional clamping of the product. 2 Il.

Silk is related to metalworking and can be used to secure products.

The aim of the invention is to increase the reliability of the fastening of the nose by introducing an additional clamp.

FIG. 1 shows a clamping device, an oblique view in section; in fig. 2 is a section A —A in FIG. one.

The clamping device comprises a base 1, in which a driving element is arranged, made in the form of a screw 2 with a spring 3. A screw 2 is connected with a freely mounted slider 4 in the base I by means of a threaded hole. On the base 1, a clamp 5 is fixed, the end of which is located in the groove made in the lower part of pos. 4. In the upper part of the slider 4 B1) 1po, 1foam bevel fi, in contact with the gland 1jumper 6. located under the action of the spring 7. In the base 1 of the device), the posterior lever 8, mounted on axis 9 and perpendicular to the axis, is closed. 1no | about the product.

The device works as follows.

After usgan (the product turns the pint 2 connected by thread with the slider 4 by the handle and they begin to move relative to each other. The spring 3 acts on the connection screw 2 - the slider 4 and the screw of the screw 2 s (Lyricococket with swing lever) (S that will begin to clamp the article

with outdoor one hundred). The latch 5, spaced in the groove of the slide 4, does not allow it to rotate around an axis.

The screw 2, moving, moves the slider 4, which by the bevel 6, made in its upper part, moves the spring-loaded plunger 6, which clamps the product along the internal opening (shaped groove) relative to the clamping element g of the base 1.

A further rotation of the handle, the end of the screw 2 will increasingly affect the swing lever 8 until the clamping forces are fully balanced. Thus, there will be a simultaneous preload of the bases of the product and its fastening.
