[0035] Working principle: During the surface polishing operation of the rubber ring mold, the operator takes the rubber ring mold and places it on the top of the supporting plate 6, controls its peripheral surface to contact the inner wall of the positioning slot 27 of the positioning and clamping rod 26, connects the air outlet pipe of the air pump to the air inlet end of the operation pipe 23, opens the valve 24 to control the air pressure to enter the inside of the driving cavity 22, so that the air pressure inside the driving cavity 22 continuously increases. Then, under the drive of the air pressure, multiple positioning and clamping rods 26 are controlled to extend outward synchronously and squeeze around the rubber ring mold to control positioning and locking installation. After locking, the valve 24 is closed for polishing operation. During polishing, the polishing dust is extracted by the suction fan 33 and enters the inside of the collection box 35 for collection. When the polishing is finished, the valve 24 is opened to control the air pressure inside the driving cavity 22 to flow out. Under the action of the tension spring 210, the positioning and clamping rod 26 is pulled back to its original position to release the locking state for disassembly.
