Intelligent laser pipe cutting machine and positioning method thereof

Abstract

The invention relates to an intelligent laser pipe cutting machine and a positioning method thereof. The intelligent laser pipe cutting machine comprises a positioning ring, a cutting ring, a control module and an input module, three telescopic clamping air cylinders are evenly distributed and fixed to the end face of one side of the positioning ring in the circumferential direction, three telescopic translation air cylinders are evenly distributed on the end face of the other side of the positioning ring in the circumferential direction, the angle between the cutting ring and a pipeline can be adjusted through movement of the three telescopic translation air cylinders, when the cutting ring is rotated, the angle is adjusted by taking an original point of an actual cutting surface formed by a tool as a rotating original point, during angle adjustment, the extension rates of two translation cylinders are controlled to be consistent and are different from the third telescopic translation cylinder, so that the angle of a cutting plane is adjusted, meanwhile, the angle adjusting range of pipelines with different pipe diameters is forecasted in advance through a laser distance measuring sensor and a position relation model, and the situation that the cutting machine and the pipelines are damaged due to the fact that the adjusting angle exceeds the limit is avoided.

Description

technical field [0001] The invention relates to a pipe cutting device, in particular to an intelligent laser pipe cutting machine and a positioning method thereof. Background technique [0002] Most of the existing pipe cutting machines use saw blades to cut the pipe body from top to bottom at multiple angles, but for large pipes with large diameter and large wall thickness, they cannot be placed on traditional pipe cutting machines for cutting. In the prior art, the frame-type pipe cutting equipment that can rotate around the pipe is fixed on the pipe by means of ring cutting, and the pipe ring is finally cut through the rotation of the tool holder around the pipe and the gradual feeding of the cutter along the radial direction of the pipe. . [0003] For the usual vertical pipe bevels, cutting can be carried out after the pipe cutting machine is positioned vertically, but there are specific requirements for the angle and orientation of the bevel (such as the bevel is at a...
