Figure 1After the orientation shown in the figure, i.e. the side opposite to the door panel 3) is opposite to the nozzle 7, the nozzle 7 can spray out the sand material to perform sandblasting on the surface of the automobile parts. By rotating the automobile parts, the top surface, bottom surface, front surface and back surface of the automobile parts can be sandblasted. When both sides of the automobile parts need to be sandblasted, the electric push rod 56 can be started to make the second motor 5 drive the connecting frame 51 to move toward the automobile parts, so that the connecting frame 51 is located between the two clamping plates 41, and the automobile parts are located on the inner side of the connecting frame 51. Then the two automatic telescopic rods 52 are started, After the two abutment plates 53 are brought close to each other, they are respectively in contact with the top and bottom surfaces of the automobile parts. At this time, the two clamping plates 41 can be kept away from the automobile parts. After the No. 2 motor 5 is started to rotate the connecting frame 51, the two abutment plates 53 can drive the automobile parts to rotate, so that one side of the automobile parts corresponds to the nozzle 7. After the sand is subsequently ejected through the nozzle 7, one side of the automobile parts can be sandblasted. After the automobile parts are rotated by the two abutment plates 53, both sides of the automobile parts can be sandblasted. Both the No. 1 motor 4 and the No. 2 motor 5 are servo motors.
