[0002] Sheet metal processing is called sheet metal working. Specifically, for example, using sheets to make chimneys, iron drums, fuel tanks, ventilation ducts, elbows, reducers, square pyramids, funnels, etc. The main processes include shearing, bending and hemming, bending and forming, welding, riveting, etc., which require certain geometric knowledge. However, during the sheet metal processing, a positioning fixture is needed to position and fix the sheet metal to improve the stability of sheet metal processing.

[0003] After retrieval, Chinese Patent Publication No.: CN215657483U discloses a positioning tooling for sheet metal processing, including a support base. The top of the support base is fixedly connected with a support plate. Openings are provided on both sides inside the support plate. Push plates are arranged on both sides of the top of the support plate. The bottom of the push plate is fixedly connected with a connecting block. By placing the sheet on the top of the support plate, after placing, rotating the rotating block, the rotating block drives the rotating rod to rotate, the rotating rod drives the pressing plate to move inwards, the pressing plate drives the moving plate to move inwards, the moving plate drives the connecting block to move inwards, and the connecting block drives the push plate to move inwards, so that the push plate contacts the surface of the sheet to clamp the sheet, thus having the advantage of being easy to use, solving the problems that the existing positioning fixture is very inconvenient to use during the use process, and if the clamping is excessive during the use process, it will damage the sheet, affecting the use effect of the positioning fixture and reducing the practicality of the positioning fixture.
