Description

Technical Field

[0001] The utility model relates to the technical field of fixing fixtures, and more specifically to a fixing fixture for laser welding. Background Art

[0002] Laser welding is a welding method that uses a focused laser beam as an energy source to generate heat to bombard the weldment. Due to the optical properties of laser such as refraction and focusing, laser welding is very suitable for welding micro parts and parts with poor accessibility. Laser welding also has the characteristics of low heat input, small welding deformation, and no influence of electromagnetic fields. In the laser welding process, the workpiece needs to be clamped and fixed in advance. At this time, a laser welding fixture is required. Among them, the "a laser welding fixture" disclosed in the application number "202220164011.3" has solved the problem of The existing fixing fixture cannot fix weldments of different sizes well. After the rod is fixed, it is not convenient to rotate the weldment, and the weldment needs to be adjusted manually, which greatly reduces the welding efficiency. However, in actual use, the fixing fixture for laser welding with similar structure still has many defects, such as: the above-mentioned file can be rotated before the workpiece is clamped, but it cannot be rotated after the workpiece is clamped, which is inconvenient to use, and the position of the workpiece cannot be adjusted as needed. After the workpiece is laser welded, its surface temperature is high, and personnel cannot directly pick it up with their hands, which is inconvenient for personnel to pick up the workpiece. In view of this, we propose a fixing fixture for laser welding. Utility Model Content
