A skeleton roughening device for bearing seal processing

Abstract

This utility model relates to the field of bearing seal processing technology, and provides a roughening device for the skeleton of bearing seal processing. It includes a worktable with several first support columns and a support plate on top of each column. The device first places the skeleton to be roughened on the fixed rod of a rotating disk and secures it with a movable rod. Then, by driving a first rotating shaft to rotate, a grinding wheel rotates. Simultaneously, by driving a second rotating shaft to rotate, the rotating disk rotates, thus rotating the skeleton. This ensures that each surface of the skeleton can be roughened. After roughening is complete, the drive device is turned off. After the rotating disk and grinding wheel stop rotating, the movable rod is released, and the skeleton is removed from the rotating disk. This increases the friction on the skeleton surface, improves the firmness between the skeleton and the seal, and prevents separation, resulting in a tighter fit between the skeleton and the seal.

Description

Technical Field

[0001] This utility model belongs to the field of bearing seal processing technology, and in particular relates to a roughening device for the skeleton of bearing seal processing. Background Technology

[0002] Bearings are important components in mechanical equipment. They are placed between relatively rotating parts to reduce friction and improve the rotational accuracy of the rotating shaft. Bearing seals are used to prevent the leakage of lubricating oil inside the bearing and to prevent external dust, impurities, etc. from entering the bearing, thereby protecting the normal operation of the bearing.

[0003] Chinese Patent Publication No. CN 212421924 U discloses a vulcanizing device for producing skeleton sealing rings. In this technical solution, the upper connecting plate is lifted by the locking mechanism, which in turn drives the clamping plate and the upper mold to move upward. The upper mold separates from the lower mold, and the clamping plate pulls the upper mold against the bottom of the main support plate. The lifting mechanism then lifts the main support plate, causing the outer sides of the main support plate and the upper mold to open. However, after the skeleton is processed, the surface is usually too smooth. The excessive smoothness of the skeleton will lead to insufficient friction between the seal and the skeleton, making it impossible for the skeleton to fit tightly. The seal is prone to separation or falling off, resulting in a decrease in sealing performance. This will not only affect the normal operation of the equipment, but also cause safety hazards. Utility Model Content

[0004] This utility model provides a roughening device for the skeleton of bearing seal processing, which aims to solve the problem that if the skeleton is too smooth, the friction between the seal and the skeleton will be insufficient and the seal will not be able to fit tightly on the skeleton.

[0005] This utility model is implemented as follows: a roughening device for the skeleton of a bearing seal processing device includes a worktable, on which a plurality of first support columns are arranged, a support plate is arranged on the top of the plurality of first support columns, and two second support columns are arranged on the top of the support plate. A second rotating shaft is rotatably arranged between the two second support columns. The two ends of the second rotating shaft extend to the outside of the two second support columns and are fixedly connected to rotating disks. A movable rod for fixing the skeleton is arranged above the surface of each rotating disk and lowerably, and a fixing rod for fixing the skeleton is arranged below the surface of each rotating disk. A first rotating shaft is rotatably arranged in the middle of the plurality of first support columns, and the two ends of the first rotating shaft extend to the bottom of the fixing rod and are fixedly connected to grinding wheels.

[0006] Preferably, each of the rotating disks has a receiving groove on its surface, and a threaded rod is vertically rotatably arranged in each receiving groove. A threaded sleeve is threadedly connected to the surface of the threaded rod, and the movable rod is fixedly connected to the surface of the threaded sleeve. A first motor is fixedly connected to the top of each rotating disk, and the top end of the threaded rod is fixedly connected to the output shaft of the first motor.

[0007] Preferably, a first gear is fixedly connected to the surface of the first rotating shaft, a receiving box is provided on the worktable, a second motor is horizontally arranged inside the receiving box, and the output shaft of the second motor is fixedly connected to a second gear that meshes with the first gear.

[0008] Preferably, a first pulley is fixedly connected to the surface of the second rotating shaft, and a second pulley is fixedly connected to the surface of the first rotating shaft. The first pulley and the second pulley are connected by belt drive.

[0009] Preferably, each of the second support columns has a through groove adapted to the second rotating shaft.

[0010] Preferably, the bottom of the workbench is provided with several support legs.

[0011] Beneficial effects

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The skeleton roughening device for processing bearing seals of this utility model first places the skeleton to be roughened on the fixed rod of the rotating disk and fixes it by the movable rod. Then, by driving the first rotating shaft to rotate, the grinding wheel will be rotated. At the same time, by driving the second rotating shaft to rotate, the rotating disk will be rotated, thereby driving the skeleton to rotate. This ensures that each surface of the skeleton can be roughened. After roughening is completed, the driving device is turned off. After the rotating disk and grinding wheel stop rotating, the movable rod is released to remove the skeleton from the rotating disk. This increases the friction of the skeleton surface, improves the firmness between the skeleton and the seal, and makes it less likely to detach or separate from the seal, making the skeleton and the seal more tightly connected.

[0017] 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.

[0018] Please see Figure 1-3 This utility model provides a technical solution: a roughening device for the skeleton of a bearing seal processing, including a worktable 1, a plurality of first support columns 2 are provided on the worktable 1, a support plate 3 is provided on the top of the plurality of first support columns 2, two second support columns 4 are provided on the top of the support plate 3, a second rotating shaft 10 is rotatably provided between the two second support columns 4, the two ends of the second rotating shaft 10 extend to the outside of the two second support columns 4 and are fixedly connected to rotating disks 5, a movable rod 8 for fixing the skeleton is provided above the surface of each rotating disk 5, a fixing rod 9 for fixing the skeleton is provided below the surface of each rotating disk 5, a first rotating shaft 6 is rotatably provided in the middle of the plurality of first support columns 2, and the two ends of the first rotating shaft 6 extend to the bottom of the fixing rod 9 and are fixedly connected to grinding wheels 7.

[0019] In this embodiment, the fixed rod 9 and the movable rod 8 are used together to fix the skeleton and prevent it from shifting or falling off during the roughening process.

[0020] The selection of grinding wheel 7 should be determined based on the material of the skeleton and the roughening requirements to ensure roughening effect and processing efficiency.

[0021] First, place the skeleton to be roughened on the fixed rod 9 of the rotating disk 5 and fix it with the movable rod 8. Then, drive the first rotating shaft 6 to rotate, which in turn drives the grinding wheel 7 to rotate. At the same time, drive the second rotating shaft 10 to rotate, which in turn drives the rotating disk 5 to rotate, thus rotating the skeleton. This ensures that each side of the skeleton can be roughened. After roughening is completed, turn off the drive device. After the rotating disk 5 and the grinding wheel 7 stop rotating, release the movable rod 8 and remove the skeleton from the rotating disk 5.

[0022] Furthermore, each of the rotating disks 5 has a receiving groove 14 on its surface, and a threaded rod 16 is vertically rotatably arranged in each receiving groove 14. A threaded sleeve 15 is threadedly connected to the surface of the threaded rod 16, and the movable rod 8 is fixedly connected to the surface of the threaded sleeve 15. A first motor 13 is fixedly connected to the top of each rotating disk 5, and the top end of the threaded rod 16 is fixedly connected to the output shaft of the first motor 13.

[0023] In this embodiment, when the skeleton to be roughened needs to be placed on the movable rod 8 and fixed rod 9 of the rotating disk 5, the first motor 13 is started first. The output shaft of the first motor 13 will drive the threaded rod 16 to rotate. Since the threaded rod 16 and the threaded sleeve 15 are connected by threads, when the threaded rod 16 rotates, the threaded sleeve 15 will move up and down along the axial direction of the threaded rod 16. After the movable rod 8 descends to the appropriate position, the skeleton is placed on the movable rod 8 and fixed rod 9 of the rotating disk 5. Then, the movable rod 8 is driven to rise until it is fixed to the front side of the rotating disk 5.

[0024] Furthermore, a first gear 12 is fixedly connected to the surface of the first rotating shaft 6, a receiving box 18 is provided on the workbench 1, a second motor 19 is arranged horizontally inside the receiving box 18, and the output shaft of the second motor 19 is fixedly connected to a second gear 20 that meshes with the first gear 12.

[0025] In this embodiment, when the grinding wheel 7 needs to be activated for roughening, the second motor 19 is started. The output shaft of the second motor 19 drives the second gear 20 to rotate. Since the second gear 20 meshes with the first gear 12, the rotation of the second gear 20 drives the first gear 12 and the first rotating shaft 6 fixedly connected to it to rotate.

[0026] Furthermore, a first pulley 11 is fixedly connected to the surface of the second rotating shaft 10, and a second pulley 17 is fixedly connected to the surface of the first rotating shaft 6. The first pulley 11 and the second pulley 17 are connected by belt drive.

[0027] In this embodiment, when the second motor 19 rotates, it drives the first rotating shaft 6 to rotate. Since the first rotating shaft 6 and the second rotating shaft 10 are connected by belt drive, the second rotating shaft 10 is driven to rotate.

[0028] Furthermore, each of the second support columns 4 is provided with a through groove 21 that is adapted to the second rotating shaft 10.

[0029] In this embodiment, the design of the through groove 21 should ensure that the second rotating shaft 10 can be smoothly inserted and fixed therein, while avoiding excessive gaps that could lead to unstable transmission.

[0030] Furthermore, the bottom of the workbench 1 is provided with several support legs 22.

[0031] The working principle and usage process of this utility model are as follows: After the utility model is installed, the skeleton to be roughened is first placed on the fixed rod 9 of the rotating disk 5 and fixed by the movable rod 8. Then, the first rotating shaft 6 is driven to rotate, which in turn drives the grinding wheel 7 to rotate. At the same time, the second rotating shaft 10 is driven to rotate, which in turn drives the rotating disk 5 to rotate, thereby driving the skeleton to rotate. This ensures that each surface of the skeleton can be roughened. After roughening is completed, the drive device is turned off. After the rotating disk 5 and the grinding wheel 7 stop rotating, the movable rod 8 is released, and the skeleton is removed from the rotating disk 5.

[0032] 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.
