Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

Furthermore, in the description of the present utility model, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "fixed" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; may be a mechanical connection; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

As shown in fig. 1, the preferred embodiment of the present utility model provides a chuck adapted to the jaws of a vertical lathe, comprising a fixture block 1 and a mounting plate 2.

The clamping block 1 is square, a V-shaped clamping groove 3 is integrally formed in the front side face of the clamping block 1, and the V-shaped clamping groove 3 is used for clamping one side of a conical surface crank workpiece 4. Specifically, the inner surface of the V-shaped clamping groove 3 includes a laterally symmetrical inclined plane and a bottom plane connecting the two inclined planes, and a plurality of protruding blocks 5 are uniformly arranged on the two inclined planes respectively to increase the friction force with the conical surface crank workpiece 4.

Connecting plates 6 are symmetrically arranged on the left side and the right side of the clamping block 1, and the connecting plates 6 are fixedly arranged in a welding mode.

Further, the connection plates 6 extend out of the rear side of the clamping block 1, and the two connection plates 6 and the rear side of the clamping block 1 form a U-shaped mounting groove 7.
