Description

Clamps are known in metalworking machines, in which the working member is a knuckle provided with a grooved rubbing surface. In order to be able to fix the position of the fist, it is proposed to place a tension cone fixed by a nut in its conical socket.

In FIG. 1 is a plan view of the proposed fixture; FIG. 2 is a side view of it; FIG. 3-11-view of parts of the device in two projections.

The device consists of a fist / (Fig. 1, 2 and 3), provided with a corrugation on its fist surface, and in its middle part with a hole. The latter consists of the lower part, made in the form of a gear with an internal tooth, and the upper-r-in the form of a conical. nest nest. The gear knob 2 (fig. 4) is placed in the lower part of the fist hole, which is thereby firmly connected to the fist. Above the arms (1) a tension cone 3 is applied, the protrusion of which falls into the fist socket. All these three parts are mounted on the sleeve 6 (Fig. 8) and fastened with an Ik 8 (Fig. 9). The sleeve 6, in turn fits on axle 5 (fig. 10) laid in

of the machine table and provided at the free end with threads for the nut 7 (Fig. 7) and the lock nut 9 (Fig. 11). To fix the part on the machine, axis 5 is installed in the corresponding slot of the table.

By turning the knob 2, the knurled fist surface is pressed onto the part until slightly jammed, and then the nuts 8 1l f are secured with a common wrench 4 (fig. B), and the protrusion of the cone 3 is installed in the hole of the cam against the point of contact of the cam with the part so that it acts by squeezing the nut into the cam socket and tensioned continuously towards the part to be fixed. Thereafter, the nut 7 and locknut 9 are fastened,

The subject matter of the invention.

A clamping device in metal-working machines using a knuckle provided with a corrugated rubbing surface and a handle, characterized in that in order to fix the position of the knuckle / serves placed in the conical nest of the knuckle and worn on its axis 5 tension cone 3 under it. impact nut.
