Positioning device

Positioning device, the device comprises a workbench, and a positioning mechanism and a supporting mechanism which are arranged on the workbench, the workbench is provided with a workpiece area used for bearing a workpiece. The positioning mechanism comprises a first positioning piece and a second positioning piece opposite to the first positioning piece. The second positioning piece can slide inthe direction close to the first positioning piece and is matched with the first positioning piece so as to position and clamp the workpiece in the workpiece area, and the position of the supporting mechanism relative to the workpiece area is adjusted so as to support and position the workpiece in the workpiece area. According to the positioning device, multiple workpieces of different shapes arepositioned through the positioning mechanism and the supporting mechanism, universality is achieved, proper adjustment can be conducted according to the shapes of the workpieces, and expandability isachieved. 一种定位装置，包括工作台、设于所述
