Pipe cutting machine rear end fixture structure

Abstract

The invention discloses a back-end fixture structure of a pipe material cutting machine, which comprises a rear clamp seat, a rear chuck and several rear clamp blocks slidably arranged on the rear chuck. A drive plate is rotatably provided on one end face, and a driving device for driving the drive plate is provided on the rear turntable, and several chutes are provided on the end of the rear chuck facing away from the drive plate, and several rear chucks Blocks are slidably arranged in the chute one by one, and a driving rod is fixed to one end of the rear clamping block relative to the rear chuck, and the driving rod passes through the rear chuck, and the driving disc is opposite to the end of the rear chuck. A driving groove is opened on the end surface, and the driving rod extends into the driving groove. In the structure of the clamp at the rear end of the pipe material cutting machine of the present invention, the rear clamp block is driven by the drive plate on the rear chuck, which greatly reduces the occupied space of the clamp.

Description

technical field [0001] The invention relates to a clamp structure, more specifically to a clamp structure at the rear end of a pipe cutting machine. Background technique [0002] The pipe cutting machine is a kind of cutting machine commonly used at present. Through the function of the cutting machine, the pipe can be cut. The structure of the existing cutting machine includes a cutting platform, which can be slidably set on the cutting platform. The cutting head and the cutting fixture are used to clamp one end of the pipe during the cutting process, and then cut through the cutting head. [0003] The structure of the existing cutting fixture generally includes a circular fixture turntable, and a plurality of chucks are arranged on the fixture turntable, and the plurality of chucks can slide on the fixture turntable, so as to realize clamping the end of the pipe material. The driving structure of the collet generally adopts the cylinder method, that is, the number of cylin...

AI Technical Summary

Problems solved by technology

[0003] The structure of the existing cutting fixture generally includes a circular fixture turntable, and a plurality of chucks are arranged on the fixture turntable, and the plurality of chucks can slide on the fixture turntable, so as to realize clamping the end of the pipe material. The driving structure of the collet generally adopts the cylinder method, that is, the number of cylinders corresponding to the collets is installed on the surface of the fixture turntable, and then the clamping and releasing action is realized by pushing the collet to slide through the cylinder. , this will cause the problem that the area of ​​the fixture turntable will become larger due to the large length occupied by the cylinder, making the cutting machine uneconomical
