Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to an anti-deformation clamp for welding automobile parts. Background Art

[0002] We know that when welding automotive parts, they first need to be fixed. The strength of automotive parts often varies depending on their size. If the clamping force is too large during clamping, it can easily cause deformation of the workpiece. For example, the Chinese patent with authorization announcement number CN 217667510 U discloses an automotive parts welding fixture. In this patent, by turning the first handle, the first handle drives the bidirectional screw to rotate. By engaging the bidirectional screw with the slider thread through an external thread and rotating it, and the other end of the bidirectional screw is rotatably connected to the second fixed plate through a bearing, the bidirectional screw can rotate more stably and drive the two sets of sliders to move closer or farther away from each other on the bidirectional screw, thereby achieving clamping. This clamping method is rigid clamping. The clamping force cannot be accurately controlled during the clamping process, which can easily cause deformation of the workpiece. For this reason, we propose an anti-deformation fixture for welding automotive parts. Summary of the Invention
