[0002] Sheet metal is a comprehensive cold working process for metal sheets (usually below 6 mm), including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming (such as automobile bodies), etc. Its remarkable feature is that the thickness of the same part is consistent. The products processed by sheet metal technology are called sheet metal parts. During the welding process of sheet metal parts, a positioning welding jig is used to position and fix the sheet metal parts, so as to ensure the smooth progress of the welding work.

[0003] The Chinese utility model with the authorization announcement number CN215787864U discloses a sheet metal part positioning welding jig. When this device is in use, the distance between the jigs can be adjusted according to the needs of the sheet, and at the same time, different-position jigs can be selected according to the welding needs. However, when this device is actually used, due to the shape limitation of the jigs, when facing circular and square sheets, the jigs cannot adapt to the shape of the sheets to clamp and fix them. At the same time, this device cannot rotate and adjust the sheet. When the welding angle needs to be adjusted, the sheet needs to be re-clamped and fixed to make corresponding angle adjustments. Therefore, it is necessary to redesign the welding positioning jig for sheet metal parts in view of the above problems. Content of the Utility Model
