Description

Technical Field

[0001] The utility model relates to a laser welding head which is easy to adjust and belongs to the technical field of laser welding. Background Art

[0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. The welding process is a heat conduction type, that is, the laser radiation heats the workpiece surface, and the surface heat diffuses to the inside through heat conduction. By controlling parameters such as the width, energy, peak power and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool. Due to its unique advantages, it has been successfully used in the precision welding of micro and small parts.

[0003] The existing patent number is CN220679682U, which is an adjustable laser welding head. This device can be installed on the device when the laser welding head body is used for welding through the overall matching design of the device. By adjusting the convenient adjustment of the sleeve on the column, the lifting height of the laser welding head body can be controlled. Through the matching design of the first adjustment rod, the second adjustment rod and the clamping member, the multi-angle adjustment of the laser welding head body can be realized, and the welding angle and welding distance of the laser welding head body can be conveniently controlled. The base can make the device convenient to move to meet the straight welding and moving use of the welded parts. However, this device can only perform straight welding on the welded parts when in use, and cannot achieve curved welding. The weld seam of the welded parts has a partially curved part, and thus the use of this device has certain limitations, affecting the welding processing effect of different workpieces; and although this device can be flexibly moved, it is difficult to accurately control, and it is difficult to automatically dock the position of the welded parts, and it is difficult to ensure the stability of the welded parts, so it is easy to offset during the welding process, affecting the final welding quality.
