Sheet metal part workbench

The utility model discloses a sheet metal part workbench. When a conventional workbench is used for machining and spraying the two faces of a sheet metal part, operation is easy; sheet metal part difficult to overturn, easily wasted manpower, according to the technical scheme, a clamping mechanism is arranged in a workbench; the clamping mechanism comprises a rotating column and a sliding block; one end of the rotating column is rotationally connected with the workbench; the other end is provided with a connecting block fixedly connected therewith; first sliding grooves symmetrical about the center of the connecting block are formed in the face, away from the rotating column, of the connecting block. The sliding blocks are connected with the first sliding grooves in a sliding mode, the upper end and the lower end of the clamping plate are fixedly connected with the sliding blocks of the two clamping mechanisms respectively, a sheet metal part is pre-fixed through friction plates on theclamping plate, and then
