Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Example 1

As shown in figures 1-4, a special-shaped part clamping jaw for a numerical control lathe comprises: the clamping jaw comprises a clamping jaw body 1, a connecting body 2 and a locking screw 3; the rear end of the jaw body 1 is provided with an inserting convex part 1a, the front end of the connector 2 is provided with an inserting groove 2a, the inserting convex part 1a of the jaw body 1 is inserted into the inserting groove 2a of the connector 2 and fixed by a locking screw 3, and the connector 2 is provided with a connecting screw hole 2 b; the lower end of the jaw body 1 is a working surface, a first arc surface 1b is arranged at the front end of the working surface of the jaw body 1, and a containing groove 1c for containing a special-shaped part is arranged in the middle of the jaw body.
