At this time, the motor 21 starts to rotate at a low speed. After rotating for a set time, the clamping and rotating system loosens the wheel hub 15 and returns it to its original position. The wheel hub 15 moves along the fourth roller 23, gradually leaving the cleaning liquid 8. When it moves to the bottom of the rear flushing assembly, the fourth electric cylinder 29 drives the second flushing hole 27 to move to a suitable distance from the wheel hub 15 through the second connecting plate 28 and starts to spray water for flushing. After flushing is completed, it is transferred to the next workstation via the roller.
