[0002] Sheet metal is a comprehensive cold working process for metal sheets, including shearing, punching, folding, welding, riveting, etc. Its remarkable feature is that the thickness of the same part is consistent. As a widely used metal part at present, sheet metal parts are not only easy to form, but also have high processing efficiency and low cost. The welding of sheet metal parts requires precise control. During the processing of sheet metal parts, multiple sheet metal parts need to be welded together, and welding is widely used as a processing and fixing method.

[0003] Tooling fixtures are usually used in sheet metal welding. However, during the use of existing tooling fixtures, there are usually some problems. When an operator uses the device, they need to first place the sheet metal to be processed on the workbench, and then determine the fixed position of the sheet metal through a positioning ruler. After determining the position, the bolts on both sides are manually tightened to fix the position of the sheet metal to be processed. Since manually positioning and fixing the sheet metal is too inefficient, it is easy to affect the welding efficiency of the sheet metal during batch welding. Content of the Utility Model
