Pipe fitting clamping mechanism of full-automatic pipe cutting machine

The utility model discloses a pipe fitting clamping mechanism of a full-automatic pipe cutting machine. The pipe cutting machine comprises a feeding drive part, a cutting drive part, a pipe fitting clamping part, a cutting part, a discharging part and a cutting measurement part which are sequentially arranged on a workbench; the pipe fitting clamping mechanism of the full-automatic pipe cutting machine is characterized in that the pipe fitting clamping part comprises a pipe fitting clamp and a driving member for the pipe fitting clamp, wherein the pipe fitting clamp comprises two semi-annular clamping elements and connected with a bilateral driving member through a connecting rod. The automatic pipe cutting machine adopts a clamping and feeding structure, an automatic cutting structure, an automatic clamping structure, an automatic discharging structure, and a pipe length measuring and controlling mechanism for pipe cutting. The pipe fitting clamping structure can be used for clamping a pipe fitting firmly, and can achieve automatic positioning and automatic aligning to the center of the pipe fitting. Therefore, the degree of automation of the pipe cutting machine is improved.
