An existing grinding device for bearing manufacturing (publication number: CN221792293U) exhibits at least the following defects during use.
[0003] The inability to position the outer or inner ring of the bearing during installation can easily lead to inconsistent heights at both ends of the outer or inner ring. If the thickness of the outer or inner ring is thinner than the fixing block, it cannot be processed. Therefore, this application proposes a grinding device for bearing production to solve this problem. Summary of the Invention

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application (for ease of description and understanding, hereinafter referred to as...), Figure 2 (The above is described above). All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.
[0017] Please see Figure 1-4 This application provides a technical solution for a grinding device for bearing production: a grinding device for bearing production includes a worktable 1, a support 2 at the bottom of the worktable 1, three guide holes 3 on the worktable 1, the three guide holes 3 are evenly distributed in a circle on the worktable 1, and two support rollers 4 are arranged between two adjacent guide holes 3, and the support rollers 4 are fixed on the worktable 1.
[0018] Specifically, the support 2 consists of support legs and a base plate. There are four support legs, which are installed on the lower surface of the workbench 1, and the base plate is set between the four support legs.
[0019] Specifically, the included angle between two adjacent guide holes 3 is 120 degrees. By setting the guide holes 3, the stability of the movement of the inner support assembly 16 and the drive assembly 6 can be improved.
[0020] The support roller 4 can support the outer ring or inner ring of the bearing, making it easier for the inner support assembly 16 to clamp the outer ring or inner ring of the bearing.
[0021] Each of the three guide holes 3 is equipped with an inner support assembly 16, which includes an inner support roller 17, a second slider 18, a second limiting plate 19, a second handwheel 20, a second lead screw 21, a moving plate 22, and a connecting rod 23. The second handwheel 20 is rotatably connected to the middle of the worktable 1. One end of the second handwheel 20 passes through the worktable 1 and is connected to the second lead screw 21. The bottom of the second lead screw 21 is rotatably connected to the bracket 2. The outer side of the second lead screw 21 is connected to the moving plate 22 through a lead screw nut. The second slider 18 is set in the guide hole 3 and is slidably connected to the guide hole 3. The upper surface of the second slider 18 is rotatably connected to the inner support roller 17. The bottom of the second slider 18 is equipped with a second limiting plate 19. The bottom of the second limiting plate 19 is hinged to a connecting rod 23. The three connecting rods 23 are hinged to the moving plate 22.
[0022] Specifically, the second slider 18 is T-shaped, with the short plate resting on the worktable 1 and the long plate slidably connected in the guide hole 3. The second limiting plate 19 is connected to the second slider 18 by bolts and is I-shaped, which can ensure the stability of the movement of the inner support roller 17.
[0023] More specifically, since the two ends of the connecting rod 23 are hinged to the second limiting plate 19 and the moving plate 22 respectively, when the moving plate 22 moves up and down, the connecting rod 23 can drive the second limiting plate 19 and the second slider 18 to slide along the guide hole 3, forming a linkage effect.
[0024] With this configuration, rotating the second handwheel 20 drives the second lead screw 21 to rotate, thereby causing the moving plate 22 to move up and down, so that the connecting rod 23 can drive the second limiting plate 19 and the second slider 18 to slide along the guide hole 3, thus realizing the clamping or loosening action.
[0025] The foremost guide hole 3 is equipped with a drive assembly 6 for rotating the outer or inner ring of the drive bearing. The drive assembly 6 includes a drive roller 7, a first slider 8, a first limiting plate 9, a drive motor 10, and a displacement assembly 11. The first slider 8 is slidably connected in the guide hole 3. The first limiting plate 9 is provided on the lower surface of the first slider 8. The drive motor 10 is provided on the lower surface of the first limiting plate 9. The power output shaft of the drive motor 10 passes through the first limiting plate 9 and the first slider 8 and is connected to the drive roller 7 above the first slider 8. The displacement assembly 11 is provided on one side of the first limiting plate 9.
[0026] Specifically, the first slider 8 is T-shaped, and the first limiting plate 9 is fixed to the first slider 8 by bolts. The first slider 8 and the first limiting plate 9 are I-shaped, which can ensure the stability of the first slider 8 and the first limiting plate 9 moving along the guide hole 3.
[0027] The drive motor 10 drives the drive roller 7 to rotate, which in turn drives the outer or inner ring of the bearing to rotate, so that the two grinding discs 31 can grind and polish the two ends of the outer or inner ring of the bearing.
[0028] Furthermore, the displacement assembly 11 includes a first handwheel 12, a fixed plate 13, a first lead screw 14, and a movable seat 15. There are two fixed plates 13, and the fixed plates 13 are located at the bottom of the workbench 1. The first handwheel 12 is rotatably connected to the frontmost fixed plate 13. The first lead screw 14 is located behind the first handwheel 12. The first lead screw 14 is connected to the movable seat 15 through a lead screw nut, and the rear end of the first lead screw 14 is rotatably connected to the rear fixed plate 13. The movable seat 15 is located on one side of the first limiting plate 9.
[0029] When the position of the drive roller 7 needs to be adjusted, the first screw 14 is rotated by turning the first handwheel 12, thereby driving the moving seat 15, the first limiting plate 9, the first slider 8 and the drive roller 7 to move along the guide hole 3, so as to drive the outer or inner ring of bearings of different sizes.
[0030] A depth adjustment group 24 is provided on the rear side of the worktable 1. The depth adjustment group 24 includes guide rails 25, a third slider 26, a connecting plate 27 and an electric push rod 28. Two guide rails 25 are set on the worktable 1. A connecting plate 27 is provided on the rear side of the two guide rails 25. An electric push rod 28 is provided on the rear side of the connecting plate 27. The telescopic end of the electric push rod 28 passes through the connecting plate 27 and is connected to the upright plate 29. The bottom of the upright plate 29 is connected to the guide rails 25 through the third slider 26.
[0031] Specifically, the guide rail 25 is fixed to the worktable 1 by bolts, and the third slider 26 is fixed to the upright plate 29 by bolts. The guide rail 25 and the third slider 26 ensure the stability of the movement of the upright plate 29, and the electric push rod 28 can adjust the front and rear position of the upright plate 29.
[0032] A vertical plate 29 is provided on the depth adjustment group 24. The vertical plate 29 is connected to the grinding motor 30 through the vertical adjustment group. Two grinding discs 31 are provided at the power output end of the grinding motor 30. The two grinding discs 31 are connected by a pad 32. A clearance groove 33 is provided on the worktable 1 corresponding to the grinding disc 31. A receiving hopper 34 is provided below the clearance groove 33 and is placed on the support 2.
[0033] Specifically, by setting the clearance groove 33, the grinding disc 31 can be prevented from contacting the worktable, and the waste material can enter the receiving hopper 34 through the clearance groove 33. By replacing different pads 32, the grinding disc 31 can be adapted to bearings of different thicknesses.
[0034] Specifically, the vertical adjustment group moves linearly and is mainly composed of a servo motor, a lead screw, a guide rod, and a mounting base. The grinding motor 30 is fixed on the mounting base. The servo motor can drive the lead screw to rotate, thereby causing the mounting base to drive the grinding motor 30 to move up and down, so that the grinding disc 31 can grind the outer or inner ring of the bearing.
[0035] In use: Adjust the position of the inner support assembly 16 and the drive assembly 10 according to the size of the bearing. First, place the outer or inner ring of the bearing on the support roller 4 and make the outer or inner ring of the bearing fit on the inner support assembly 16. Then, turn the second handwheel 20 to drive the second lead screw 21 to rotate, thereby driving the moving plate 22 to move up and down, so that the connecting rod 23 can drive the second limit plate 19 and the second slider 18 to slide along the guide hole 3, so that the inner support roller 17 moves toward the inner hole of the outer or inner ring of the bearing to achieve the clamping action.
[0036] Subsequently, rotating the first handwheel 12 drives the first lead screw 14 to rotate, thereby causing the moving seat 15, the first limiting plate 9, the first slider 8 and the drive roller 7 to move along the guide hole 3 toward the outside of the bearing, so that the drive roller 7 contacts the outside of the bearing. Then, the drive motor 10 drives the drive roller 7 to rotate, thereby causing the drive roller 7 to drive the outer ring or inner ring of the bearing to rotate.
[0037] The height of the two grinding discs 31 is adjusted by the vertical adjustment group, and the electric push rod 28 drives the upright plate 29, the vertical adjustment group, the grinding motor 30, the grinding discs 31, and the third slider 26 to move along the guide rail 25 toward the outer or inner ring of the bearing, so that the two grinding discs 31 can grind and polish the two end faces of the outer or inner ring of the bearing.
[0038] After grinding is completed, the depth adjustment group 24 drives the grinding disc 31 to move backward to reset. Then, the second handwheel 20 is rotated so that the connecting rod 23 can drive the inner support roller 17 away from the outer or inner ring of the bearing. After that, the worker can replace the bearing for grinding.
[0039] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
