[0012] Compared with the prior art, the present invention adopts the above structure to achieve the following beneficial effects: 1. The mobile component and the limit placement mechanism are closely linked through the telescopic adjustment component. Before grinding, the air pump controls the flow direction and pressure of the gas to make the cylinder 1 and the cylinder 2 move synchronously, thereby realizing the position adjustment of the grinding component and the limit placement mechanism and the fixation of the sealing ring.

At the same time, the air pump can also drive the grinding component to approach the sealing ring and maintain a suitable grinding pressure by controlling the expansion and contraction of the cylinder 1; 2. During the movement of the mobile sleeve of the mobile grinding mechanism, the piston cylinder 1 and the piston cylinder 2 of the dust extraction and conveying mechanism are driven to work. While the grinding assembly is grinding the sealing ring to produce debris, the dust extraction and conveying mechanism absorbs and collects the debris in time. The two operate synchronously, which improves the work efficiency and keeps the working environment clean. 3. The driving motor of the driving mechanism not only drives the sealing ring on the limiting roller to rotate, but also drives the threaded rod to rotate through gear transmission, thereby moving the movable sleeve block, so that the grinding assembly can grind different positions of the sealing ring. The various components work together to improve the overall grinding effect; 4. The moving assembly and the grinding assembly in the mobile grinding mechanism cooperate with each other. The moving assembly drives the grinding assembly to move back and forth, and the driving mechanism drives the sealing ring to rotate, so as to realize the multi-directional and full-circle grinding of the sealing ring and ensure the uniform grinding effect; 5. When the pressure in the debris collection tank increases to a certain level, the sealing ball overcomes the elastic force of the spring under the action of the pressure difference and is pushed away from the spherical opening of the spherical port plate, allowing the gas to be discharged through the pressure relief port, thereby reducing the pressure in the tank, ensuring the stable operation of the entire dust extraction and conveying system, and extending the service life of the equipment.

Under the same pressure difference principle as above, the movable rod 1 3312 extends and the movable rod 2 612 contracts. The movable rod 2 612 retracts the limiting roller 62 into the housing 2. At the same time, the movable rod 1 3312 drives the grinding assembly 32 to approach the sealing ring 8 on the limiting roller 62, and the gas on the bottom side of the cylinder 1 331 is transported to the cavity of the limiting roller 62 through the air pipe 1 334. The airbag strip 64 filled with gas tightens the sealing ring 8. After the limiting airbags 63 on both sides are filled, they block and limit the two outer sections of the sealing ring 8. The driving motor 51 runs, and drives the cylinder 2 61 to rotate through the transmission belt 55, and the cylinder 2 61 drives the sealing ring 8 on the limiting roller 62 to rotate. At the same time, the driving motor 51 drives the driving gear 52 to rotate, and the driving gear 52 drives the driven gear 54 to rotate through the transmission gear 53, and the driven gear 54 drives the threaded rod 311 to rotate, so that the movable sleeve block 312 moves, and the grinding assembly 32 performs multi-directional grinding on the sealing ring 8. During the grinding process, the dust extraction and conveying mechanism 4 works synchronously, and the movement of the movable sleeve block 312 drives the piston cylinder 1 41 and the piston cylinder 2 42 to work. When the movable sleeve block 312 moves to the left, it also drives the piston rod 1 412 and the piston rod 2 422 to move to the left, and the piston plate 1 411 and the piston plate 2 421 move to the left at the same time, and the piston cylinder 1 41 passes through the piston cylinder 1 41 The dust suction pipe 44 on the piston cylinder 42 and the dust suction nozzle 3231 on the protective cover 323 absorb the debris generated during grinding into the right chamber of the piston cylinder 1 41, and the debris impurities in the left chamber of the piston cylinder 2 42 are transported to the debris collection tank 7 by the conveying pipe 45 on the piston cylinder 2 42 through the pressure difference. When the movable sleeve 312 moves to the right, it drives the piston rod 1 412 and the piston rod 2 422 to move to the right at the same time. The piston cylinder 2 42 absorbs the debris generated during grinding into the left chamber of the piston cylinder 2 42 through the dust suction pipe 44 on the piston cylinder 2 42 and the dust suction nozzle 3231 on the protective cover 323, and the debris impurities in the right chamber of the piston cylinder 1 41 are transported to the debris collection tank 7 by the conveying pipe 45 on the piston cylinder 1 41 through the pressure difference. When the grinding work is in progress, the debris is adsorbed and collected in the debris collection tank 7; During the process of the conveying pipe 45 continuously conveying the debris into the debris collection tank 7, the pressure in the debris collection tank 7 will continue to increase. As the air pressure continues to increase, the blocking ball 712 is affected by the pressure difference and moves to the outside of the pressure relief port 71. The gas flows out through the gap between the blocking ball 712 and the open end of the pressure relief port 71, and the gas is dispersed to the outside through the filter screen 711 to relieve the pressure in the debris collection tank 7, thereby ensuring that the pressure inside the debris collection tank 7 is stable. After the grinding is completed, the preparatory steps are repeated, the limiting roller 62 is extended out of the housing 2, and the polished sealing ring 8 is removed.
