[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a grinding device for the outer edge of a rubber bearing seal, including a workbench 1, a support plate 2 rotatably disposed in the middle of the workbench 1, a conical cylinder 3 for placing the bearing seal disposed on the support plate 2, a support ring 18 for placing the bearing seal detachably sleeved on the surface of the conical cylinder 3, a vertical plate 28 disposed on the workbench 1 and located behind the conical cylinder 3, a horizontal plate 14 disposed on the front side of the vertical plate 28 that can be raised and lowered, and two horizontal bars 13 that can move inward and are used to press and disassemble the support ring 18 are disposed on the front side of the horizontal plate 14.

[0021] The tapered design of the tapered cylinder 3 helps to stably place and remove the bearing seal, ensuring stability during grinding and polishing of the bearing seal on the tapered cylinder 3.

[0022] The support ring 18 can be replaced with different sized bearing seals to suit different sizes of bearing seals.

[0023] The crossbar 13 is used to press the bearing seal on the support ring 18 downwards, and the support ring 18 provides support to ensure that the bearing seal is fixed on the tapered cylinder 3. After processing, the bearing seal can be replaced by lifting the support ring 18 upwards using the crossbar 13.

[0024] When it is necessary to replace the support ring 18 or remove the bearing seal, the drive bar 13 is moved to the bottom of the support ring 18, and then the drive plate 14 drives the bar 13 to rise, thereby replacing the support ring 18 or removing the bearing seal.

[0025] Both ends of the workbench 1 are slidably provided with sliders 4, each slider 4 is vertically provided with a column 5 at its top, and each column 5 is provided with a sliding plate 10 that can be raised and lowered on its inner side. A grinding roller 7 is rotatably provided below one sliding plate 10, and a polishing roller 17 is rotatably provided below the other sliding plate 10.

[0026] In this embodiment, the grinding roller 7 is used to perform preliminary grinding on the workpiece.

[0027] Polishing roller 17 is used to further polish the workpiece.

[0028] When the bearing seal needs to be processed, firstly, the support ring 18 is fitted onto the surface of the conical cylinder 3. Then, the bearing seal is placed on the support ring 18 and fixed by pressing down the crossbar 13. Then, the bearing seal is rotated by rotating the conical cylinder 3. Next, a sliding plate 10 is driven to move the grinding roller 7 close to the bearing seal. Then, the sliding plate 10 is driven to rise and fall until it is flush with the bearing seal, so that the outer edge of the bearing seal can be ground. After grinding, the grinding roller 7 returns to its position. Then, another sliding plate 10 is driven to move the polishing roller 17 close to the bearing seal. Then, the sliding plate 10 is driven to rise and fall until it is flush with the bearing seal, so that the outer edge of the bearing seal can be polished. After polishing, the polishing roller 17 returns to its position.

[0029] Furthermore, each of the columns 5 has a receiving groove, and each receiving groove has a lead screw 6 vertically rotatably installed. The surface of the lead screw 6 is threaded with a first threaded sleeve 8. Each sliding plate 10 is fixedly connected to the surface of each first threaded sleeve 8. A first motor 9 is vertically installed at the top of each column 5. The top of the lead screw 6 is fixedly connected to the output shaft of the first motor 9. A second motor 11 is vertically installed at the top of each sliding plate 10. The middle part of the grinding roller 7 is fixedly connected to the output shaft of one of the second motors 11, and the middle part of the polishing roller 17 is fixedly connected to the output shaft of the other second motor 11.

[0030] In this embodiment, when the bearing seal needs to be ground and polished, the first motor 9 is started to drive the lead screw 6 to rotate. As the lead screw 6 rotates, the first threaded sleeve 8 moves up and down on the surface of the lead screw 6, thereby driving the sliding plate 10 to rise and fall. After rising and falling to a position flush with the bearing seal, the second motor 11 is then started to drive the grinding roller 7 or polishing roller 17 below the sliding plate 10 to rotate, thus performing the grinding and polishing process on the bearing seal.

[0031] Furthermore, the upper surface of the workbench 1 has horizontal grooves at both ends, and each horizontal groove has an electric slide rail 20 arranged horizontally. Each electric slide rail 20 has a sliding block 19 slidably arranged on its surface, and each slider 4 is fixedly connected to the upper surface of the sliding block 19.

[0032] In this embodiment, when the bearing seal needs to be processed, the sliding block 19 is first driven to slide by starting the electric slide rail 20. Since the sliding block 19 is fixedly connected to the slider 4, the slider 4 is driven to slide, thereby driving the column 5 to move to the appropriate position.

[0033] Furthermore, a placement slot 21 is provided in the middle of the workbench 1, and a placement plate 22 is provided in the placement slot 21. A rotating shaft 23 is vertically rotatably provided on the placement plate 22. The top end of the rotating shaft 23 is fixedly connected to the bottom of the support plate 2. A gear 24 is fixedly connected to the surface of the rotating shaft 23. An electric telescopic rod 27 is provided on the placement plate 22 and on one side of the rotating shaft 23. A connecting rod 26 is fixedly connected to one end of the electric telescopic rod 27. A rack 25 that meshes with the gear 24 is fixedly connected to one end of the connecting rod 26.

[0034] In this embodiment, when grinding and polishing the outer edge of the bearing seal, the electric telescopic rod 27 is activated. The electric telescopic rod 27 extends or shortens its length, causing the connecting rod 26 and the rack 25 to move together. Since the rack 25 meshes with the gear 24, the movement of the rack 25 will drive the rotation of the gear 24. The rotation of the gear 24 will drive the rotating shaft 23 to rotate around its axis, thereby driving the support plate 2 to rotate, which in turn drives the bearing seal on the conical cylinder 3 to rotate, thus achieving the grinding and polishing treatment of the outer edge of the bearing seal.

[0035] Furthermore, a groove is provided in the vertical plate 28, and a first threaded rod 29 is vertically rotatably arranged in the groove. A second threaded sleeve 16 is threadedly connected to the surface of the first threaded rod 29. The horizontal plate 14 is fixedly connected to the surface of each second threaded sleeve 16. A third motor 12 is vertically fixedly connected to the top of the vertical plate 28, and one end of the first threaded rod 29 is fixedly connected to the output shaft of the third motor 12.

[0036] In this embodiment, when it is necessary to press down or remove the support ring 18, the third motor 12 is started, and the output shaft of the third motor 12 begins to rotate. Since the output shaft is fixedly connected to the first threaded rod 29, the first threaded rod 29 will also rotate. As the first threaded rod 29 rotates, the second threaded sleeve 16, which is threaded to it, will move up and down on the first threaded rod 29, thereby driving the cross plate 14 to move up and down together, thereby driving the cross bar 13 to move up and down.

[0037] Furthermore, a drive groove is provided in the horizontal plate 14, and a bidirectional threaded rod 30 is rotatably arranged in the drive groove. Both ends of the surface of the bidirectional threaded rod 30 are threadedly connected to a third threaded sleeve 31. Each horizontal bar 13 is fixedly connected to the surface of each third threaded sleeve 31. A fourth motor 15 is fixedly connected to one end of the horizontal plate 14, and one end of the bidirectional threaded rod 30 is fixedly connected to the output shaft of the fourth motor 15.

[0038] In this embodiment, when it is necessary to press down on bearing seals of different sizes, or when it is necessary to remove the support ring 18, the fourth motor 15 is started to drive the bidirectional threaded rod 30 to rotate, thereby driving the two third threaded sleeves 31 to slide, thereby driving the crossbar 13 to move synchronously to both sides, thus achieving the adaptation to bearing seals of different sizes.

[0039] When it is necessary to remove the support ring 18, the crossbar 13 is adjusted to be wider than the support ring 18, and then the drive plate 14 is lowered to below the support ring 18. Then, the position of the crossbar 13 is adjusted to be below the support ring 18, and then the crossbar 13 is raised by raising the plate 14, thereby removing and replacing the support ring 18.

[0040] The working principle and usage process of this utility model are as follows: After the utility model is installed, firstly, the support ring 18 is sleeved on the surface of the conical cylinder 3. Then, the bearing seal is placed on the support ring 18 and fixed by the crossbar 13. Then, the bearing seal is rotated by rotating the conical cylinder 3. Next, a sliding plate 10 is driven to move the grinding roller 7 close to the bearing seal. Then, the sliding plate 10 is driven to rise and fall until it is flush with the bearing seal, so that the outer edge of the bearing seal can be ground. After grinding, the grinding roller 7 returns to its position. Then, another sliding plate 10 is driven to move the polishing roller 17 close to the bearing seal. Then, the sliding plate 10 is driven to rise and fall until it is flush with the bearing seal, so that the outer edge of the bearing seal can be polished. After polishing, the polishing roller 17 returns to its position.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
