When the closing disk (402) is pulled out of the guide groove (309) by the second electric push rod (401), the bearing ring on the upper surface of the closing disk (402) can be sequentially dropped to the upper surface of the conveyor belt (404) through the connecting opening (310) and the drop opening (105). The conveyor belt (404) is transmission-mounted in the docking plate (405), and the docking plate (405) is fixedly mounted on the lower surface of the operating table (1); Two groups of barrier strips (403) are fixedly mounted on the upper surface of the docking plate (405), and the two groups of barrier strips (403) slide on the surface of the conveyor belt (404), and the upper surfaces of the barrier strips (403) touch the lower surface of the operating table (1) and enclose the drop opening (105); The debris suction collection mechanism (2) comprises a dust collector (201), and both sides of the outer surface of the collection cylinder (202) of the dust collector (201) are connected and installed with suction pipes (203), and the other end of the suction pipe (203) is fixedly installed with an expansion port (204); The expansion openings (204) are located on both sides of the grinding head of the grinding machine (104) through the extension of the suction pipe (203); the two groups of the expansion openings (204) are inclined at 45 degrees and can move together with the movement of the first linear module (101), the second linear module (102) and the third linear module (103), so that during the process of the grinding machine (104) processing the groove of the bearing ring, the expansion openings (204) can keep following; When processing the bearing rings, multiple groups of bearing rings are stacked and placed in a C-shaped cylinder (302) for storage, and then a top cover (303) is installed on the upper surface of the C-shaped cylinder (302). The top cover (303) installed on the upper end of the C-shaped cylinder (302) drives the limit column fixedly installed on the lower surface to be inserted into the inner ring of the stacked bearing rings, so that the bearing sleeves can be in a vertical shape during the process of falling from the C-shaped cylinder (302), and can prevent tilting or dislocation, thereby ensuring the accuracy and stability of automatic feeding; After the bearing rings are stacked, the first electric push rod (304) is started to pull the bearing plate (306) at one end of the piston rod to slide on the lower surface of the C-shaped cylinder (302) until the first electric push rod (304) pulls the first arc groove (307) opened at one end of the bearing plate (306) to be flush with the C-shaped cylinder (302), and then stops. The bottom of the C-shaped cylinder (302) flush with the first arc groove (307) is no longer blocked, and a group of the stacked bearing rings in the C-shaped cylinder (302) will fall vertically into the first arc groove (307), and the remaining bearing rings will hit the upper surface of the bearing rings in the first arc groove (307) and be confined in the C-shaped cylinder (302); Then, the first electric push rod (304) is started again to push the bearing plate (306), so that the bearing plate (306) can block the bottom of the C-shaped cylinder (302), and at the same time, the bearing ring in the first arc groove (307) is pushed to slide on the upper surface of the guide plate (305) and approach the second arc groove (308), and as the first electric push rod (304) continues to push, the bearing ring can be clamped in the first arc groove (307) and the second arc groove (308); Subsequently, the grinding wheel machine (104) grinds the inner ring of the clamped bearing ring through the linkage of the first linear module (101), the second linear module (102), and the third linear module (103), so as to process the groove. The grinding wheel machine (104) controlled by the linkage of the first linear module (101), the second linear module (102), and the third linear module (103) enables the grinding wheel machine (104) to move freely along the X-axis, the Y-axis, and the Z-axis and to provide precise feed control, thereby ensuring the depth and precision of the grinding process, and further enabling the bearing ring to be accurately positioned in multiple directions during the groove processing, thereby ensuring the precision of the processing process; After the processing of the bearing ring is completed, the first electric push rod (304) and the second electric push rod (401) are started simultaneously, and the first electric push rod (304) pulls the first arc groove (307) at one end of the bearing plate (306) to fall off from the surface of the bearing ring, thereby releasing the clamping force, and with continued pulling, another set of bearing rings can fall into the first arc groove (307) again for filling; The second electric push rod (401) will pull the closing disk (402) to slide into the guide groove (309). During the sliding process of the closing disk (402), the bearing ring on the upper surface will contact one end of the second arc groove (308) and slide on the surface of the closing disk (402) at the same time; The closing disk (402) that slides into the guide groove (309) will expand the communication port (310) at the lower end, thereby enabling the bearing ring to sequentially pass through the communication port (310) and the drop port (105) and fall onto the surface of the conveyor belt (404) to be transported away for the next processing or centralized collection operation.
