[0002] In the production process of some automotive parts, some parts that need to be welded need to be limited and tightened first, and the connecting rod is contacted with the workpiece, and then the workpiece is welded by welding equipment. In order to meet the requirements of automated welding, the workpiece needs to be clamped and tightened quickly.

[0003] For example, the patent with publication number CN108817818B discloses a special-shaped pipe welding fixture, which limits the outer contour of the air inlet of the special-shaped pipe through multiple support rods, and then clamps the special-shaped pipe through a clamping device to improve the clamping stability.

The automated welding tool cannot weld multiple welding points at one time, and the workpiece needs to be turned around or flipped, which affects the welding efficiency.

[0005] Based on this, the utility model designs a welding fixture for automobile parts with multiple welding points to solve the above problems. Utility Model Content
