A laser head for multi-directional angle adjustment for laser welding

Abstract

The invention discloses a laser head for multi-directional angle adjustment for laser welding, which relates to the field of welding technology, in particular to a laser head for multi-directional angle adjustment for laser welding, including a slide rail, an inner tooth sleeve and a main air pipe. A slide block is installed in the middle of the slide rail, and a stainless steel shell is installed above the slide block, a strut is installed above the inner gear sleeve, and the internal gear sleeve is located above the stainless steel shell, and a stainless steel shell is installed above the strut There are servo motors. This laser welding uses a laser head that is convenient for multi-directional adjustment of the angle. Through the cooperation between the compressor, the main air pipe, and the blowing pipe, the inert gas inside the gas storage tank can be effectively introduced into the inside of the blowing pipe. When the laser head is on the workpiece When doing work, the blowing pipe blows the inert gas to the welding part of the workpiece to prevent the rapid oxidation of the welding part of the workpiece, and it is easy to generate impurities in the welding part, resulting in the weak welding part of the workpiece and failing to achieve the required working effect.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a laser head for multi-directional angle adjustment for laser welding. Background technique [0002] In the pillar industries of the national economy such as metallurgy, shipbuilding, and automobiles, it is a common method to use lasers to weld relatively small metal sheets into relatively large sheets or to weld relatively short metal sheets or strips into relatively long sheets or strips. , this production process is called laser tailor welding. For example, when a roll rolls a relatively thick plate into a relatively thin plate, in order to continue production, lasers are widely used on the production line to weld the end of the previous roll of plate with the end of the rear plate. The front end of a roll of sheet metal is welded. This welding can make the rolling process continue for the desired time. This production process is called on-line laser tailor welding. [0003]...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a laser head for multi-directional angle adjustment for laser welding, which solves the problem that the position between the laser head and the workpiece cannot be adjusted well according to the position of the workpiece, and the position between the laser head and the workpiece cannot be adjusted well according to the workpiece. The angle of the laser head can be adjusted at the welding part, and the laser head cannot be moved according to the working conditions to increase the working range of the laser head. Rapid oxidation, a problem raised in the background art above
