Description

Technical Field

[0001] The utility model relates to the technical field of laser welding clamping devices, in particular to a handheld laser welding clamping device. Background Art

[0002] In modern manufacturing, welding, as an important connection process, is widely used in the production process of various products. Welding operations are usually also required when processing and preparing handicrafts. At present, the requirements for welding quality and efficiency are getting higher and higher when performing welding operations. Compared with traditional rod welding operations, laser welding has the advantages of significantly improving welding efficiency and reducing pollution.

[0003] However, when laser welding is performed, it is usually carried out on a corresponding laser welding machine. Such laser welding machines are usually provided with a corresponding welding platform. During the specific operation, the workpiece is clamped and fixed on the welding platform through the clamping components on the welding platform, thereby achieving the effect of clamping and fixing.

[0004] However, this type of fixation can only limit the workpiece to the welding platform. Due to the different welding paths in the laser welding process, some welding paths are relatively complex. In this case, directly fixing the workpiece to the welding platform is difficult to achieve the flexible adjustment welding effect. It is not conducive to the staff to hand-hold the workpiece and then manually hold the workpiece for flexible adjustment welding, which affects the flexible welding effect and brings inconvenience to the user. In view of this, we propose a handheld laser welding clamping device. Utility Model Content
