A pusher head 2912 is installed on the piston end of the rejection cylinder 2911. A stacking plate 2913 is installed on the side of the annular conveyor line 23 corresponding to the rejection cylinder 2911. Bearing parts that fail to meet the ball loading requirements or the retaining frame loading requirements are rejected by the rejection cylinder 2911 and pushed onto the stacking plate 2913.

[0046] A processing method for an automatic assembly of bearing inner and outer ring retainer equipment, wherein an outer ring sorting mechanism 12 and an inner ring sorting mechanism 13 respectively select the outer ring and inner ring of the bearing that meet the size, and place the outer ring and inner ring of the bearing that meet the size on the outer ring sorting disk 14 and the inner ring sorting disk 15 respectively, and select steel balls according to the groove clearance between the paired inner and outer rings of the bearing. In this embodiment, five ball storage tanks are provided in the ball placement station 164, and the five ball storage tanks store steel balls of different precision sizes. During the pairing process of the inner and outer rings of the bearing, since the outer ring sorting disk 14 and the inner ring sorting disk 15 are driven by separate DD motors, the outer ring or the inner ring of the bearing can be paired with the corresponding 1 to 6 inner rings or the outer ring of the bearing according to the program setting, and the groove clearance is controlled. If the groove clearance is a positive tolerance, it means that the groove gap is large, and a positive tolerance steel ball is matched. If the groove clearance is a negative tolerance, It means that the groove gap is small and it is matched with negative tolerance steel balls. For example, if the groove clearance is zero size, it is matched with nominal size steel balls. If the appropriate steel balls cannot be matched, it means that the groove clearance is out of tolerance. The receiving cylinder sends the bearing outer ring and the bearing inner ring into the receiving box 111 respectively, and the successfully matched bearing outer ring and bearing inner ring are sent to the ball loading mechanism 16 for ball loading. The inner and outer rings of the bearing after ball loading are transferred to the retaining frame device 2 through the conveyor belt device 3, and the inner and outer rings of the bearing are sent to the loading trolley 221 through the transfer device 23. The balls are magnetically divided by the ball averaging station 24, and the steel balls are evenly divided again by the ball dividing station 25. The distribution of steel balls in the bearing is then tested by the ball dividing detection station 26. The qualified bearings are mounted with retainers by the retaining frame installation station 27, and then tested by the retaining frame detection station 28. The bearings with unqualified ball distribution and the bearings with unqualified retaining frame installation are rejected by the rejection station 29.

Those skilled in the art may make some modifications or changes without departing from the spirit of the present invention, that is, within the scope of disclosure. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
