Laser combined welding head regulating mechanism

Abstract

The invention relates to a laser combined welding head regulating mechanism, which comprises a welding gun, a laser head, an aluminum alloy plate, a spiral sleeve, a sleeve holder, a guide post, a rack, a gear, a knob and a clamping sleeve, wherein the spiral sleeve is sleeved in a hole in the aluminum alloy plate; the laser head is arranged on the spiral sleeve; the sleeve holder is fixed on the aluminum alloy plate through a screw; the guide post and the rack are arranged in a sleeve on the sleeve holder; the gear is embedded on the knob; the clamping sleeve is connected with the guide post through a first butterfly nut; and the welding gun is arranged on the clamping sleeve and is fixed by a second butterfly nut. In the invention, the structure of the mechanism is reasonable, the manufacturing of the mechanism is convenient and the manufacturability of the mechanism is high; the position relationship of the laser head and the welding gun can be regulated flexibly according to different requirements of a welding process, so as to regulate a light-thread distance and the angle of the welding gun; and the welding gun may be a tungsten electrode argon arc welding gun, a consumable arc welding gun or a plasma arc welding gun; the laser head may be a yttrium aluminum garnet (YAG) laser or an optical fiber laser welding head; and the application range of the combined welding head regulating mechanism can be enlarged.

Description

technical field [0001] The invention relates to a laser composite welding head adjustment mechanism, in particular to a laser-arc composite welding device for adjusting the relative position of a laser head and a welding torch, and belongs to the technical field of mechanical equipment. Background technique [0002] In the laser welding process, the requirements for thick plate welding are very high, requiring high laser power (kilowatt level or even 10,000 watt level), strict weld seam butt flatness, and the gap should not be greater than 0.2mm, so the cost of thick plate laser welding is very high. high. Laser arc hybrid welding can significantly reduce the requirements for laser power through the interaction between laser and arc, so that the composite heat source with small and medium power can achieve the welding effect of high power laser, improve energy utilization rate, and strengthen the bridging of weld seam at the same time capacity, reducing processing costs. ...

AI Technical Summary

Problems solved by technology

[0003] However, in the existing technology, the laser head and the welding torch are integrated, and it is almost impossible to adjust the relative position between the two, and it is impossible to explore the composite welding process, resulting in a narrow range of product application
