In the drawings and description, similar or identical parts are referred to by the same reference numerals, and in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this utility model are merely illustrative and not intended to limit the scope of this utility model. Any obvious modifications or changes made to this utility model do not depart from its spirit and scope.

[0024] In one embodiment, such as Figure 1-5 As shown, a surface grinding device for bearing processing includes a base 1, and further includes:

[0025] The grinding cylinder 9 has a support sleeve 2 on the base 1. Support frames 3 are fixedly installed on both sides of the support sleeve 2. A connecting block 4 is fixedly installed on the top of the support frame 3. A crossbeam 5 is fixedly installed between the two connecting blocks 4. A fixed plate 6 is fixedly installed at the center of the crossbeam 5. A turntable 7 is rotatably installed on the fixed plate 6. An installation groove 701 is opened on the turntable 7. A movable block 8 is slidably installed inside the installation groove 701. A support rod 22 is installed between the two movable blocks 8. The ends of the two sets of support rods 22 that are close to each other are slidably inserted into the interior of the grinding cylinder 9. The support rods 22 are elastically connected to the interior of the grinding cylinder 9 by elastic elements such as springs.

[0026] The grinding disc 10 has a fixed plate 21 vertically mounted on the top of the base 1. A rotating rod 12 is positioned between the two fixed plates 21, and a connecting pipe 121 is positioned between the two rotating rods 12. The connecting pipe 121 is fixedly mounted on one rotating rod 12, and one end of the other rotating rod 12 slides into the interior of the connecting pipe 121. Two sets of support sleeves 2 are positioned away from each other, allowing the connecting rod 12 to slide out of the interior of the connecting pipe 121, facilitating the insertion and removal of the bearing body 11. A sleeve 24 is provided on the outside of the rotating rod 12. A telescopic rod 25 is slidably arranged inside the sleeve 24. The telescopic rod 25 is elastically installed inside the sleeve 24. The spring inside the sleeve 24 limits and compresses the telescopic rod 25, so that the grinding disc 10 is tightly attached to the inner ring of the bearing body 11. One end of the telescopic rod 25 passes through the sleeve 24 and is provided with the grinding disc 10. Multiple bearing bodies 11 are sequentially sleeved on the outside of the grinding disc 10. A rotating ring 19 is rotatably arranged on the outside of the rotating rod 12. The rotating ring 19 cannot move left or right. A connecting rod 23 is rotatably arranged between the rotating ring 19 and the movable block 8.

[0027] The drive mechanism, connected to the rotating rod 12, can drive the grinding cylinder 9 and the grinding disc 10 to rotate.

[0028] The bearing surface grinding device drives the rotating rod 12 and the rotating ring 19 to rotate via a drive mechanism. The rotating ring 19 drives multiple grinding cylinders 9 to rotate via a connecting rod 23. The bearing body 11 is sleeved on the outside of the grinding disc 10, so that the grinding disc 10 contacts the inner ring of the bearing body 11, and the multiple grinding cylinders 9 contact the outer ring of the bearing body 11. The grinding cylinders 9 and the grinding disc 10 rotate and grind the bearing body 11, which can simultaneously grind the inner and outer rings of the bearing. As an embodiment, the left, right, up, and down positions of the various components shown in the attached drawings are only one arrangement method, and the specific positions are set according to specific needs.

[0029] In one embodiment, such as Figure 1-3 As shown, the driving mechanism includes a driving rod 14, a rotating disk 16, and a connecting column 18. The rotating disk 16 is rotatably mounted on the fixed plate 21. The rotating rod 12 passes through the rotating disk 16 and rotates in cooperation with it. A connecting column 18 is provided between the rotating disk 16 and the rotating ring 19. The driving rod 14 is mounted on the fixed plate 21. A transmission belt 13 is provided between the driving rod 14 and the rotating rod 12. The driving rod 14 drives the rotating rod 12 to rotate through the transmission belt 13.

[0030] In one embodiment, such as Figure 1-3As shown, a motor 15 is mounted on the fixed plate 21. The rotating end of the motor 15 is connected to the drive rod 14. A gear disk 161 is mounted on the outside of the rotating disk 16. A gear 17 that meshes with the gear disk 161 is mounted on the outside of the drive rod 14. The motor 15 drives the drive rod 14 to rotate, and the drive rod 14 drives the rotating disk 16 to rotate through the meshing of the gear set. This makes the rotation direction of the rotating disk 16 opposite to that of the rotating rod 12, and the rotation direction of the grinding cylinder 9 opposite to that of the grinding disc 10, resulting in a better grinding effect on the inner and outer rings of the bearing.

[0031] In one embodiment, such as Figure 1-3 As shown, a lead screw 20 is rotatably installed inside the base 1. The two ends of the lead screw 20 are provided with external threads in opposite directions. The support sleeve 2 has a threaded hole that mates with the lead screw 20. By rotating the lead screw 20 through the handle, the lead screw 20 causes the two support sleeves 2 to move closer or further apart. When the two support sleeves 2 move closer together, the support sleeves 2 cause the two sets of fixed discs 6 to move closer together. The fixed discs 6 cause the movable block 8 to move. The end of the connecting rod 23 near the rotating ring 19 cannot move. The connecting rod 23 pulls the movable block 8 closer together, so that multiple sets of grinding cylinders 9 move closer together, ensuring tight contact between the grinding cylinder 9 and the outer ring of the bearing.

[0032] In one embodiment, such as Figure 4 As shown, a limiting groove 702 is provided on the outside of the turntable 7, and the turntable 7 is rotatably disposed inside the fixed plate 6 through the limiting groove 702.

[0033] The above embodiments of this utility model provide a surface grinding device for bearing processing. Two sets of support sleeves 2 are far apart, so that two sets of rotating rods 12 are separated from each other. Multiple bearing bodies 11 are sequentially sleeved on the outside of the grinding disc 10. The two sets of support sleeves 2 are close to each other. The fixed disk 6 drives the movable block 8 to move. The connecting rod 23 pulls the movable block 8 closer to each other, so that multiple sets of grinding cylinders 9 are close to each other. The grinding cylinders 9 are in contact with the outer ring of the bearing. The motor 15 drives the drive rod 14 to rotate. The drive rod 14 drives the rotating disk 16 to rotate through the meshing of the gear set. The rotation direction of the rotating disk 16 is opposite to that of the rotating rod 12. The rotation direction of the grinding cylinders 9 is opposite to that of the grinding disc 10, so that the inner and outer rings of the bearing can be ground at the same time.

[0034] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
