The specific working process is as follows: in an initial state, the position of the material returning groove 204 on the drive roller group is as shown in fig. 10, at this time, the oilstone chuck 609 is located outside the positioning sleeve, and is in a compression state of the limiting spring 305, when the bearing outer ring 5 needs to be superfinished, the bearing outer ring 5 to be machined only needs to be placed into the material feeding groove 102, and at this time, the bearing outer ring 5 to be machined is limited at the position of the material outlet of the material feeding groove 102 by the limiting mechanism.

During the processing, the hydraulic cylinder 301 is started, the push rod 302 is in a contracted state, and then the arc-shaped connecting rod 604 is driven to move, because the limiting spring 305 is in a compressed state, the positioning sleeve group can synchronously move along with the arc-shaped connecting rod 604, when the positioning sleeve group moves to the lower part of the upper trough 102, the upper convex plate 404 of the positioning sleeve group is matched with the limiting plate 105 on the limiting mechanism, and then the limiting plate 105 is compressed, namely the fixture block 106 is separated from the bearing outer ring 5 to be processed at the upper discharge port of the upper trough 102, and then the bearing outer ring 5 to be processed drops into the positioning sleeve group, and continuously moves to the position of the positioning block 104 along with the positioning sleeve group, at this time, the flange 603 on the rotating shaft enters the bearing outer ring 5, and then the push rod 302 is continuously contracted, because the positioning sleeve group is limited by the positioning block 104, the push rod 302 drives the arc-shaped connecting rod 604 to continuously move, and when the oilstone chuck 609 moves to the position matched with the cam rim 603 and stops as shown in fig. 9, then the motor 201 is started, and further the transmission gear 208 is respectively matched with the left gear 205, the right gear 206 and the high-speed gear 211 to drive the transmission roller set and the rotating shaft 601 to rotate, the bearing outer ring 5 to be processed in the positioning sleeve set can be driven to rotate through the rotation of the transmission roller set, meanwhile, the rotating shaft 601 can drive the oilstone chuck 609 to swing along the hinged position through the matching of the cam edge 603 and the swinging shaft 610, further the coarse superfine grinding processing of the oilstone 7 on the groove of the bearing outer ring 5 is realized, when the processing is stopped for a period of time, the motor 201 drives the ring gear sliding sleeve to slide through the gear shifting rod 213, further the transmission gear 208 is separated from the matching of the high-speed gear 211, the low-speed gear 210 and the gear shifting gear 207 are matched, further the gear shifting is realized through the rotation of the rotating shaft 601, the motor 201 is continuously started after the gear shifting is finished, and further the fine superfine grinding processing is realized through the low speed.

The material returning process, after the finishing and ultra-finishing process, the motor 201 is turned off, then the hydraulic cylinder 301 is turned on, the push rod 302 extends, because the limit spring 305 is always in a compressed state, when the push rod 302 just begins to extend, the oilstone chuck 609 moves forward along with the arc-shaped connecting rod 604, the positioning sleeve stops moving under the action of elasticity, when the upper ring of the push rod 302 contacts with the upper fixing block 406 of the positioning sleeve, the positioning sleeve is driven to move together, at the moment, the oilstone chuck 609 withdraws from the inside of the outer bearing ring 5 on the positioning sleeve and moves along with the positioning sleeve, when the positioning sleeve moves to the lower part of the upper trough 102, because the outer bearing ring 5 in the positioning sleeve contacts with the outer bearing ring 5 to be processed at the discharge port of the upper trough 102, namely, the outer bearing ring 5 in the upper trough 102 cannot drop, when the positioning sleeve moves to the position of the material returning trough 204, the outer bearing ring 5 drops from the material returning trough 204 to the lower trough 107, and then the material pushing block 403 is rolled to match with the material pushing block 403 in the stacking groove 103, in the whole material returning process, the material pushing block 403 moves along with the positioning sleeve group, so that the outer ring 5 of the bearing rolled to the position of the stacking groove 103 in the previous material returning process can be pushed into the stacking groove 103, and the outer ring 5 of the bearing in the next material returning process can be ensured to be rolled to the position of the stacking groove 103 and not to be stacked in the material discharging groove 107, and then the resetting process of the positioning sleeve group is the next material loading processing process, and the steps are as described above.
