An expansion clamp 12 is arranged on the rotating drive assembly, the expansion clamp 12 can be expanded to be tightly attached to the inner cavity of the workpiece and drive the inner cavity of the workpiece to rotate.

[0022] The driving and lifting assembly comprises a telescopic cylinder 2, which is a long-stroke thin cylinder and is vertically arranged on the upper surface of the first mounting plate 1. The telescopic rod of the telescopic cylinder 2 is arranged upward and fixedly connected with the second mounting plate 3, so as to drive the second mounting plate 3 to lift.

[0023] The rotating drive assembly comprises a plurality of rotating shafts 6, which are longitudinally arranged and arranged side by side along the vertical surface. The top of the rotating shaft 6 is rotationally connected with the second mounting plate 3, the bottom of the rotating shaft 6 penetrates through the second mounting plate 3 and is connected with an end transmission shaft 9, the bottom of the end transmission shaft 9 is connected with a transmission rubber head 10, and the bottom of the transmission rubber head 10 is connected with a working head 11. The working head 11 is a working head for completing a cleaning action or a working head for completing a blowing action. When the working head 11 is a working head for completing a cleaning action, a guide shaft 7 is sleeved on the rotating shaft 6, the guide shaft 7 is coaxially arranged and fixedly connected with the rotating shaft 6; a plurality of guide seats 8 are arranged through the first mounting plate 1, the guide seats 8 are arranged and slidably assembled with the guide shafts 7 one by one, and the guide seats 8 are used to penetrate through the guide shafts 7 to realize guiding.

[0024] The rotating drive power assembly comprises a speed reducer motor 4, which is fixedly arranged on the second mounting plate 3, and the output shaft of the speed reducer motor 4 is connected with the input end of the rotating power transmission assembly. The rotating power transmission assembly comprises a plurality of gears 5 which are rotationally arranged and meshingly connected with each other, and the top of the rotating shaft 6 is fixedly connected with the corresponding gear 5. When the speed reducer motor 4 is started, each rotating shaft 6 is driven to rotate synchronously by the gear 5, and each working head 11 is driven to rotate synchronously by each rotating shaft 6.

[0025] The expansion clamp 12 comprises an air bag, which is embedded on the side wall of the working head 11. The air bag is connected with a rubber hose, which is used to connect with an air source, so as to inflate the air bag to realize the expansion of the air bag.

The rotating driving power assembly starts to rotate, and the rotating power transmission assembly evenly distributes the torsion to each rotating driving assembly, so as to drive the inner cavity of the workpiece to rotate. The rotating driving power assembly completes the rotating action, and the cleaning (or blowing) is completed within the predetermined beat time. The expansion clamp 12 on the rotating driving power assembly stops inflating, and the expansion clamp 12 retracts and resets to be separated from the inner cavity of the workpiece to generate a gap. The telescopic rod of the telescopic cylinder 2 retracts, and the rotating driving power assembly, the rotating power transmission assembly and the rotating driving assembly are lifted until the to-position detection assembly sends a to-position signal. The utility model completes a rotating cleaning (blowing) action cycle.
