step two: and (3) carrying out hot start on the polishing mechanism: the central controller (4) controls the air compressor (37) to start, the air compressor (37) starts to deliver generated compressed gas into the vortex tube (38) through the power pipeline (40), the compressed gas enters the vortex tube (38) to generate cold air and hot air, the cooling pipeline (39) delivers the cold air into the liquid storage tank (6) to cool polishing liquid, the hot air enters the hot air delivery pipeline (42), the central controller (4) controls the polishing air pump (11) to start, the polishing air pump (11) sucks a part of the hot air into the polishing air bag (16) through the exhaust tube (14), the hot air is convenient for enhancing the ductility of the polishing air bag (16), the polishing air bag (16) is prevented from being damaged due to cold start of the polishing air bag (16) in weather, the central controller (4) controls the electric telescopic rod (8) to start, the electric telescopic rod (8) extends to drive the rotary box body (10) to descend through the connecting plate (9), the rotary box body (10) drives the polishing air bag (16) to be close to the inner ring of the bearing through the rotary pipeline (18), the polishing air pump (11) conveys hot air into the telescopic hose (12) through the air outlet pipe (13) through the air exhaust pipe (14), the telescopic hose (12) conveys the hot air into the rotary box body (10), the hot air in the rotary box body (10) enters the rotary pipeline (18) through the air inlet (19), the hot air in the rotary pipeline (18) enters the polishing air bag (16) through the air outlet (20) to be filled, the polishing air bag (16) is expanded to drive the polishing abrasive paper (17) to be attached to the inner ring of the bearing, the other part of the hot air is discharged through the hot air discharge pipeline (41), the central controller (4) controls the three-phase coil (22) to be electrified, the rotary pipeline (18) rotates under the action of the magnetic fields of the three-phase coil (22) and the power magnet (23), the rotary pipeline (18) drives polishing sand paper (17) to rotate through the polishing air bag (16) to polish the inner ring of the bearing, and the rotary pipeline (18) drives fan blades (21) to rotate to blow dust generated by polishing into the liquid storage tank (6);

step three: and (3) filtering the polishing solution: the central controller (4) controls the filter pump (29) to be started, the filter pump (29) pumps polishing liquid in the liquid storage tank (6) through the liquid pumping pipeline (30), the polishing liquid enters the filter tank body (54) through the liquid outlet pipeline (31), the polishing liquid entering the filter tank body (54) impacts the power blade (25), the power blade (25) is impacted by the polishing liquid and then drives the power rotating shaft (26) to rotate, the power rotating shaft (26) drives the stirring blade (27) to rotate so as to stir and transmit the polishing liquid, the central controller (4) controls the impurity-absorbing electromagnet (28) to be electrified, the impurity-absorbing electromagnet (28) is electrified to generate magnetism to adsorb metal impurities in the polishing liquid, the filtered polishing liquid flows out of the polishing pipeline (32) through the filter opening (35) and is sprayed to a bearing which is polishing, and the polishing liquid falls down and returns to the inside of the liquid storage tank (6);

step four: the method comprises the following steps of (1) cleaning the residual impurities in the liquid storage tank (6): central controller (4) control waterproof electric putter (44) start, waterproof electric putter (44) extension drives screen board (45) and slides along liquid reserve tank (6) inner wall and rises, screen board (45) rise to the opening part of liquid reserve tank (6), clear up the impurity that falls on screen board (45), after the clearance, central controller (4) control waterproof electric putter (44) shorten and drive screen board (45) and slide to the initial position along liquid reserve tank (6) inner wall.
