Abstract

The invention discloses a novel universal joint handheld laser welding gun. Two veering reflector parts which are rotatably connected mutually are arranged between a collimating mirror part and a focusing reflector part, a gun nozzle part is arranged at the outer side of a protection mirror part, one end of the gun nozzle part is connected with a protection air pipe, and the other end, at an outlet of a photoemission channel, of the gun nozzle part is of an arc structure; each veering reflector part comprises a right-angle shell provided with a light channel and a reflective part which is arranged inside the light channel and conducts right-angle reflection on a light path, each right-angle shell is rotatably connected with the collimating mirror part and the focusing reflector part, a gunhandle part is arranged on the focusing reflector part, and a protection part for protecting the photoemission channel is arranged on the protection mirror part. According to the novel universal joint handheld laser welding gun, by adding a veering mechanism on the basis of an existing laser welding gun, changing the structure of the gun nozzle part of the welding gun, and increasing the veeringdegree of freedom of the joint of cables, the blowing direction of shielding gas is changed, the situation that weld dust residues enter the photoemission channel, and adhere to and contaminate the protection mirror part is prevented, it is avoided that due to swinging of the cables, optical fiber cables are broken off, and meanwhile, the working efficiency is improved.

Description

Technical field:

[0001] The invention relates to the field of laser welding, in particular to a novel hand-held laser welding torch with a universal head. Background technique:

[0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology. In the 1970s, it was mainly used for welding thin-walled materials and low-speed welding. The welding process is heat conduction, that is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses to the inside through heat conduction. By controlling the width, energy, peak power and repetition frequency of the laser pulse and other parameters to melt the workpiece and form a specific molten pool. Due to its unique advantages, it has been successfully applied in the precision welding of micro and small parts.
