Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of welding heads, in particular to an improved welding head for handheld laser welding. Background Technique
[0002] As a new type of welding equipment, the handheld laser welding machine has been widely used in the metal processing field with its characteristics of high efficiency, precision, and environmental protection. Compared with traditional welding methods, the handheld laser welding machine has the advantages of simple operation, fast welding speed, small heat-affected area, and beautiful weld seams, and is especially suitable for welding various metal materials such as stainless steel, carbon steel, and aluminum alloy.
[0003] For the existing handheld laser welding machine, when adjusting the length of the welding head, the staff needs to manually rotate the nut of the welding head part of the laser welding machine to adjust the length of the welding head. However, when the nut rotates by a large amplitude, the welding head is likely to slip out from the inside of the laser welding machine. When fixing the position of the welding head, the staff needs to rotate the nut. Since the laser welding machine is relatively heavy, the staff needs to support the laser welding machine with one hand and rotate the nut with the other hand. During the process of rotating the nut, it is necessary to limit the position of the welding head, which is rather troublesome. Therefore, it needs to be improved. Content of the Utility Model

[0028] Furthermore, there are two fixing rods 25, and the two fixing rods 25 are respectively fixedly connected to the inner side of the vertical plate 23.
