[0026] The working steps of this embodiment are as follows: in the first step, the steel wheel enters from the loading area 2, the swivel arm 1005 is opened, and the logistics manipulator places the steel wheel vertically between the first spray rod 1003 and the second spray rod 1002, and places it on the load-bearing shaft 10013 of the two loosened first clamps 1001 and the second clamps 1006. The spray plate 10016 plays a guiding and anti-dumping role. The first clamp 1001 and the second clamp 1006 at the bottom are started, the locking cylinder 10014 drives the load-bearing shaft 10013 to rotate, and the motor 10011 drives the card joint 10017 to rotate, thereby vertically stabilizing the steel wheel. The logistics manipulator disengages from the loosened steel wheel and evacuates.

[0028] Step 3: Secondary cleaning, the motor 10011 of the first clamp 1001 works to drive the meshed steel wheel to rotate, and the speed can be adjusted steplessly; the matrix nozzles of the two spray plates 10016 spray against each other, and the nozzle angles and spray branch combinations are set according to the program for different wheel specifications to clean both sides of the wheel, and the water pressure is adjustable; the second clamp 1006 and the nozzles on the first clamp 1001 accelerate the dirt removal process and improve the all-round rinsing effect. During the above process, the rotating arm 1005 maintains pressure and monitors whether the steel wheel rotates safely, and transfers to the next station.

[0029] Step 4: The motor 10011 of the first gripper 1001 works to drive the meshed steel wheel to rotate, and the speed can be adjusted steplessly; the matrix nozzle (high-pressure gas purge) of the spray plate 10016 sprays against each other, and the nozzle angle and spray branch combination work according to the program setting for different wheel types, and purges both sides of the wheel, and the air pressure is adjustable; the second gripper 1006 is provided with a drying top wind outlet to accelerate the drying process and improve the all-round drying effect; in the above process, the rotating arm 1005 maintains the pressure and monitors whether the steel wheel rotates safely. Transfer to the next station.

[0030] Step 5: The rotation limit releases the steel wheel, and the logistics manipulator lifts the steel wheel away.

[0031] The beneficial effects of this embodiment are as follows: compared with the linear assembly line, the five-station rotary method is more convenient for centralized control and saves floor space. The steel wheel fixed clamping drive device adopts a three-point limit clamping method, which is highly safe and can clean 360 degrees without obstruction. It has strong versatility and can meet the needs of wheels of different specifications, simplifying the process and time of changing types. A fixed matrix combination nozzle spray plate 10016 is set to protect and guide the upper and lower positions of the steel wheel, and simple and efficient cleaning is achieved through water pressure control and multi-angle combination. The working area is driven by hydraulic pressure to achieve movement, with high load-bearing capacity, reliable control and high precision. There is no electrical intervention in the cleaning area, which avoids safety accidents, has good durability and high reliability. The nozzles of the spray plate 10016 spray against each other. For wheels of different specifications, the nozzle angle and the spray branch combination work according to the program setting to clean both sides of the wheel.
