Abstract
Description
Technical Field
[0001] This utility model relates to laser welding technology, specifically a user-friendly handheld laser welding machine. Background Technology
[0002] As is well known, handheld laser welding equipment is a highly efficient and precise welding method that uses a high-energy-density laser beam as a heat source. A handheld laser welding machine mainly consists of a laser unit and a welding unit, combining the flexibility, efficiency, and high weld quality of laser welding. It can effectively weld metal materials such as carbon steel, stainless steel, and galvanized sheet, and is suitable for butt welding, lap welding, internal and external fillet welding, arc welding, and irregular shape welding.
[0003] When using existing handheld laser welding machines to weld metal plates, the welding angle of the laser welding machine needs to be adjusted as required, and the welding nozzle of the laser welding machine needs to be aligned with the joint between the two metal plates before welding. During the welding process, the welder needs to move the laser welding machine and keep the welding nozzle aligned with the joint. However, some joints are long, requiring the welder to hold the welding machine for a long time, which can easily cause fatigue in the welder's arm, causing the welding machine to shake, reducing welding accuracy, and affecting welding efficiency.

[0006] Preferably, the moving unit includes a column and rollers, the top of the column is fixed to the crossbeam, and the rollers are rotatably connected to the bottom of the column.
[0007] Preferably, the inner wall of the cross frame is provided with a slider, and the outer wall of the lifting frame is provided with a guide rail that slides with the slider.
[0008] Preferably, the side wall of the cross frame is threaded with a fixing bolt, and the end of the fixing bolt abuts against the lifting frame.
