Step one: the inner ring of the deep groove ball bearing to be treated is placed in a groove between a press block guide rail (61) and a support clamp (65), a cam bearing follower (62) is fixed by a screw, and the inner ring of the ball bearing, the inner side of which is required to be treated, is fixed by matching a connecting plate spring (64);

Step two: after the positioning in the last step is finished, the first rotating motor (3) is driven, the output end of the first rotating motor (3) controls the supporting disc (4) to rotate, the rotating follow-up bracket (42) is matched with the rotating driving plate (43) for driving the top end of the rotating follow-up bracket to contact, and therefore the transmission connection supporting plate (44) drives the processing disc (6) at the top end to rotate through the transmission connection bracket (55);

Step three: when grinding treatment operation is required, the control cylinder (23) at the top end of the fixed support (2) is driven, the control cylinder (23) is output, the control hook (24) is controlled to output under the limit of the hook rotating shaft (25), the control hook (24) is moved to the position at the top end of the processing disc (6), the press block guide rail (61) can be buckled, the cam bearing follower (62) is blocked by the control hook (24), the processing disc (6) is moved towards the bottom end, the rotating moving groove (41) is pushed by the pushing connecting rod (60), the supporting disc (4) is moved towards the bottom end, the supporting spring (33) at the bottom end is pushed to shrink in the process of moving the supporting disc (4) towards the bottom end, the rotating follow-up bracket (42) at the top end of the supporting disc (4) is not contacted and matched with the rotating driving plate (43), and the rotating driving plate (43) is not pushed to rotate by the rotating follow-up bracket (42) any more, and the rotating follow-up bracket is in a stop state;

Step four: the working drill (85) drives the working drill (88) at the bottom to rotate through the driving of the drill motor (84), the working drill (88) moves towards the bottom, and the lifting push plate (53) at the top end of the auxiliary fixing support (52) is matched to push the auxiliary fixing push frame (54) to fix, so that the grinding treatment of the inner ring of the deep groove ball bearing is realized;

step five: at the same time of the working treatment of the previous step, the inclined bracket (71) at the other end is matched with the rotary screw (722) connected with the driving motor (721) at the outer side of the inclined bracket by utilizing the fixed gear (711) at the top end, so that the rotary screw (722) outputs, the rotary screw (722) rotates at the outer side of the fixed gear (711), the angle of the connecting and fixing bottom plate (72) changes, the connecting and fixing bottom plate (72) drives the connecting and fixing support plate (74) to overturn through the moving cabin (73), the cleaning nozzle (76) at the inner side of the cleaning and fixing clamp (75) can be driven to overturn, the positions of the cleaning nozzle (77) and the side nozzle (78) are also adjusted, the working position of the cleaning surface is reached, and the cleaning nozzle (76) and the side nozzle (78) are utilized to output to the inner ring of the deep groove ball bearing at the bottom end, so that the cleaning treatment is realized.
