[0033] In the utility model, the working steps of the device are as follows:

[0034] The first step: the workpiece to be processed is placed on the conveyor belt 8, and the conveyor belt 8 can drive the workpiece to slowly move into the shot blasting chamber 1. When the position of the workpiece deviates, the drive motor 906 is started to drive the gear 902 to rotate, and at the same time drive the two racks 903 to move horizontally in different directions, so that the two positioning plates 904 are close to each other, the workpiece is clamped and positioned, the position of the workpiece is corrected, and the position of the workpiece is prevented from easily deviating, and the rack 903 can be limited by the limit block 905 when it moves horizontally;
