[0031] Working principle: First, place the automobile wheel hub on the conveying unit 2. The conveyor belt 25 provided on the conveying unit 2 is driven by the power roller 22. The conveyor belt 25 drives the automobile wheel hub to move. When the automobile wheel hub moves to the bottom of the clamping unit 3, the conveying unit 2 stops. Then, the lifting hydraulic rod 34 starts to descend, so that the clamp 38 and the automobile wheel hub are on the same horizontal plane. At this time, the clamping hydraulic rod 37 is started, and the output end of the clamping hydraulic rod 37 drives the clamp 38 to perform a clamping operation, so that the automobile wheel hub is firmly clamped by the clamp 38.

Then the clamp pushes out the shot blasting unit 1, and the closed door 116 descends to close the shot blasting unit 1. The shot blasting unit 1 starts to work, and the power motor 13 drives the turntable 131 to rotate. At the same time, the impeller 15 is started, and the shot is thrown out by the impeller 15 at a high speed and hits the automobile wheel hub. The turntable 131 drives the automobile wheel hub to rotate, so that the automobile wheel hub can be shot blasted from multiple angles and in all aspects; Finally, after the processing on one side of the automobile wheel hub is completed, the sealed door 116 is opened, the clamp 38 re-clamps the automobile wheel hub, the lifting hydraulic rod 34 drives the automobile wheel hub to rise, and then the flip motor 35 is started, and the flip motor 35 drives the clamping arm 36 to flip, so that the clamp 38 clamps the automobile wheel hub and flips it 180°. Then, the automobile wheel hub is placed on the turntable 131 again for shot blasting until the shot blasting is completed.

[0032] The clamping unit 3 clamps the automobile wheel hub and places it on the conveyor belt 25, and the conveyor belt 25 continues to move. When the next automobile wheel hub that has not been shot blasted moves to the bottom of the clamping unit 3, the above operation is repeated.
