[0034] The bearing ring is placed on the positioning end of the positioning assembly 2, then the two polishing ends of the clamping and polishing assembly 3 are driven to be in contact with the outer surface and the inner wall of the bearing ring, then the lifting and extruding assembly 5 is driven, so that the extruding end of the lifting and extruding assembly 5 can extrude the bearing ring downward, at this time the driving assembly 6 can drive the lifting and extruding assembly 5 to rotate, and the rotating lifting and extruding assembly 5 drives the bearing ring to rotate on the positioning assembly 2, and the clamping and polishing assembly 3 polishes the outer surface and the inner wall of the bearing ring.

[0035] In an embodiment, for the above-mentioned positioning assembly 2, the positioning assembly 2 comprises adjusting blocks 201, a plurality of adjusting blocks 201 are arranged in an array on the bottom of the machining table 1, a plurality of adjusting grooves 202 are opened on the top of the machining table 1 corresponding to the adjusting blocks 201, a positioning rod 203 is rotatably connected in the adjusting groove 202, the positioning rod 203 is rotatably connected with the corresponding adjusting block 201, and a support disc 204 is fixedly connected to the outer surface of the positioning rod 203.

[0036] The bearing ring is placed on the support disc 204, at this time the positioning rods 203 are in the interior of the bearing ring, then the adjusting blocks 201 are moved, so that the positioning rods 203 are in contact with the inner wall of the bearing ring, at this time the positioning rods 203 can position the bearing ring, and the positioning rods 203 can prevent the bearing ring from deviating when rotating.

[0037] In one embodiment, for the above-mentioned processing table 1, the bottom of the processing table 1 is rotatably connected with a plurality of adjusting screws 205 corresponding to the adjusting blocks 201, the adjusting screws 205 are threadedly connected with the corresponding adjusting blocks 201, one end of each of the adjusting screws 205 is fixedly connected with a bevel gear 206, the bevel gears 206 are meshed with each other, the bottom of the processing table 1 is fixedly installed with a receiving box 207 corresponding to the bevel gears 206, and the adjusting screws 205 are rotatably connected with the receiving box 207.

[0038] By rotating one of the adjusting screws 205, the rotating adjusting screw 205 drives all the adjusting screws 205 to rotate through the meshed bevel gears 206, so that the adjusting blocks 201 can be synchronously moved under the driving of the corresponding adjusting screws 205, and the positioning rods 203 can be synchronously moved under the driving of the corresponding adjusting blocks 201.

[0039] In one embodiment, for the above-mentioned clamping and polishing assembly 3, the clamping and polishing assembly 3 comprises a bidirectional screw 301 rotatably connected to the bottom of the processing table 1, the outer surface of the bidirectional screw 301 is threadedly connected with two second mounting frames 302, the inside of the second mounting frame 302 is movably connected with a T-shaped sleeve plate 303, the outer surface of the T-shaped sleeve plate 303 is sleeved with a polishing frame 304, the top of the processing table 1 is provided with a blanking groove 305, the polishing frame 304 is arranged in the inside of the blanking groove 305, the bottom of the processing table 1 is fixedly connected with a fixed rod 306, and the fixed rod 306 is movably connected with the second mounting frame 302.

[0040] By rotating the bidirectional screw 301, the two second mounting brackets 302 can move simultaneously toward the bearing ring under the drive of the bidirectional screw 301 and the guidance of the fixing rod 306. This allows the polishing frames 304 on the two second mounting brackets 302 to contact the outer surface and inner wall of the bearing ring respectively. This arrangement allows the two polishing frames 304 to polish the outer surface and inner wall of the bearing ring simultaneously when the bearing ring rotates. The polishing debris will fall directly to the bottom of the processing table 1 through the discharge groove 305. The two movable second mounting brackets 302 allow the two polishing frames 304 to polish bearing rings of different thicknesses. When replacing the polishing frame 304, it can be directly pulled out from the outer surface of the T-shaped socket plate 303, and then the new polishing frame 304 can be fitted onto the outer surface of the T-shaped socket plate 303.
