A welding torch adjustment device for laser arc hybrid welding

Abstract

The invention discloses an adjustment device of a laser-electric arc combined welding gun. The adjustment device comprises a laser head clamping sleeve and the welding gun. The welding gun is connected with the laser head clamping sleeve sequentially through an angle adjustment mechanism, a front-and-back adjustment mechanism, an up-and-down adjustment mechanism and a left-and-right adjustment mechanism. The laser head clamping sleeve is connected with a laser welding head. The angle adjustment mechanism comprises a welding gun clamping sleeve, a guide column clamping sleeve, an angle adjustment guide column and an angle adjustment screw. The front-and-back adjustment mechanism comprises a sliding guide rail, a rack and a gear in the front-and-back direction, wherein the rack is meshed with the gear. The up-and-down adjustment mechanism comprises a sleeve base, a high-low-direction guide column with a rack and a high-low-direction gear, wherein the guide column is meshed with the gear. The left-and-right adjustment mechanism comprises a left-and-right adjustment screw, and the left-and-right adjustment screw penetrates through a long hole in the sleeve base to be fixed to the laser head clamping sleeve. Operation is easy and convenient, the structure is reasonable, manufacturing is convenient, the position of laser beams of the welding gun in three-dimensional space can be accurately adjusted, and the angle adjustable range is greatly expanded.

Description

technical field [0001] The invention relates to a laser-arc compound welding torch, in particular to a laser-arc compound welding torch adjustment device. Background technique [0002] Since the British scholar Steen proposed the laser arc hybrid welding technology in the late 1970s, its advantages such as higher process stability, easy control of weld formation and joint performance, and stronger joint gap bridging ability have attracted widespread attention. There are many process parameters of laser-arc hybrid welding, among which the relative position of laser, arc and workpiece is an important factor affecting the quality and forming effect of laser-arc hybrid welding, so an adjustment method that can continuously adjust the relative position of welding torch and laser head The device will be very beneficial to hybrid welding test research. [0003] Patent CN103111781A discloses a laser composite welding head adjustment device, which is characterized in that the connec...
