[0027] When removing burrs from the bearing ring, the bearing ring is placed in the middle position of the support plate 4, and then the servo motor 5 is turned on. Then the output end of the servo motor 5 drives the first bidirectional lead screw 6 to rotate, and then the first bidirectional lead screw 6 drives the two moving frames 7 to rotate. Then the moving frames 7 are subjected to the resistance of the support plate 4, so that the two moving frames 7 move relative to each other along the outer surface of the first bidirectional lead screw 6. Then the two moving frames 7 drive the two soft suction cups 8 to move relative to each other, thereby adjusting the horizontal position of the soft suction cups 8, which is convenient for fixing bearing rings of different sizes. When the soft suction cups 8 are attached to the bearing rings , by turning on the vacuum pump 11, the vacuum pump 11 absorbs the air between the soft suction cup 8 and the bearing ring, so that negative pressure is formed inside the soft suction cup 8, thereby fixing it to the bearing ring, and then closing the valve, turning on the hydraulic pump 2, and then the hydraulic pump 2 pushes the support plate 4 upward through the rotating motor 3, and then the support plate 4 pushes the bearing ring upward to adjust the bearing ring to the same horizontal line as the grinding part 14 and the polishing part 15, and then turning on the rotating motor 3, and then the rotating motor 3 drives the bearing ring to rotate through the support plate 4, and the bearing ring undergoes grinding and polishing processes to achieve the purpose of burr removal.

[0031] By turning on the electric push rod 16, the output end of the electric push rod 16 pushes the two connecting blocks 17 to make relative motion, and then the connecting block 17 drives the two rollers 19 to make relative motion through the connecting rod 18. The two rollers 19 are against the inner wall of the bearing ring, and the rollers 19 are rotatable. The rollers 19 are displaced relative to the bearing ring, thereby sliding onto the central axis of the bearing ring, so that the bearing ring is located at the center of the support plate 4, thereby ensuring the burr removal effect of the bearing ring.

[0033] Working principle: when using the burr removal device for the bearing ring, the bearing ring is placed in the middle position of the support plate 4, and then the servo motor 5 is turned on, and then the two soft suction cups 8 are driven to move relative to each other, so as to adjust the horizontal position of the soft suction cup 8, which is convenient for fixing bearing rings of different sizes, and the vacuum pump 11 is turned on to form a negative pressure inside the soft suction cup 8, so as to fix the soft suction cup 8 and the bearing ring together, thereby improving the stability of the bearing ring, and then the hydraulic pump 2 is turned on to adjust the bearing ring to the same horizontal line as the grinding piece 14 and the polishing piece 15, and then the staff drives the second bidirectional screw 9 to rotate through the handle 10, and then the moving block 13 is restricted by the workbench 1 to move toward each other along the outer surface of the second bidirectional screw 9, driving the grinding piece 14 and the polishing piece 15 to move toward each other, so that the grinding piece 14 and the polishing piece 15 are in contact with the outer wall of the bearing ring, and then the rotating motor 3 is used to rotate the bearing ring, so as to achieve the purpose of grinding and polishing at the same time, thereby improving work efficiency.
