Pipeline laser welding machine

Abstract

The invention discloses a pipeline laser welding machine. The pipeline laser welding machine comprises a motor rotary table arranged on a machine base and a clamping and locating device. The clampingand locating device comprises a locating frame and a pipeline clamping mechanism arranged above the center of the electric rotary table. A pipe joint locating device is arranged in the position, belowthe pipeline clamping mechanism, of the electric rotary table. The electric rotary table is provided with a laser welding device. The laser welding device comprises a laser alignment assembly connected with a laser generator, a light path guide assembly and a laser focusing assembly. The laser alignment assembly is fixed to the position, below the center of the electric rotary table, of the machine base. The light path guide assembly is fixedly mounted on the electric rotary table. One end of the light path guide assembly corresponds to the laser alignment assembly, and the other end of the light path guide assembly is connected with the laser focusing assembly. The laser focusing assembly points towards the location between the pipeline clamping mechanism and the pipe joint locating device. Accordingly, the problem that an optical fiber is twined onto equipment easily and fatigue failure is caused is effectively solved, and bending deformation is caused to gas pipe to be welded due to swing can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of laser welding, in particular to a pipeline laser welding machine. Background technique [0002] When the existing gas pipe laser welding machine welds the gas pipe and the pipe joint, it either realizes the welding of the joint by rotating the gas pipe and the pipe joint, or completes the welding by turning the laser welding device around it; When the gas pipe is welded, due to the long length of the gas pipe, it is easy to swing during the rotation process, which is easy to cause bending deformation, especially the corrugated pipe is easy to break; and the laser welding device is used to weld in circles, and the optical fiber is easy to be wound on the equipment. , and it is also easy to cause fiber damage due to fatigue damage. Therefore, it is necessary to improve and optimize the existing technology. Contents of the invention [0003] The purpose of the present invention is to solve at least one o...
