Description

Technical Field

[0001] This utility model relates to the field of rubber sealing ring technology, specifically a grinding device for producing rubber sealing rings. Background Technology

[0002] A rubber seal ring is an annular cover composed of one or more parts, fixed to one ring or washer of a bearing and in contact with another ring or washer or forming a narrow labyrinth gap to prevent lubricating oil leakage and foreign object intrusion, thus providing a good sealing effect. During the production and processing of rubber seal rings, to ensure their smooth appearance, their surface needs to be polished. In existing technologies, the polishing devices for rubber seal rings are inconvenient to fix during polishing due to the annular shape of the rubber seal ring, making it prone to deflection and rotation, thus affecting the polishing quality. Therefore, to solve this problem, this invention was developed, designing a polishing device for the production of rubber seal rings. Utility Model Content

[0019] Example 1: Please refer to Figure 1-4 A grinding device for producing rubber sealing rings includes a base plate 4. A servo motor 3 is installed at the center of the top of the base plate 4, and the output end of the servo motor 3 is connected to a driving bevel gear 15. A grinding table 1 is installed at the top of the base plate 4, and four internal clamping plates 13 are arranged at equal angles inside the grinding table 1. Threaded rods 6 are installed around the bottom of the grinding table 1 via bearings, and one end of the threaded rod 6 is connected to a driven bevel gear 16. Threaded blocks 2 are sleeved on the outside of the threaded rods 6, and a connecting rod 5 is welded to the top of the threaded blocks 2. Positioning holes are opened around the outer perimeter of the grinding table 1. 17. Four lead screws 14 are provided on the outside of the grinding table 1. One end of the lead screw 14 passes through the inside of the positioning hole 17 and is connected to the outer clamping plate 7 through the bearing. Support rods 18 are bolted to the top of the bottom plate 4. The top of the support rods 18 is bolted to the top plate 10. The bottom of the top plate 10 is provided with a mounting plate 9. A grinding motor 12 is mounted on the bottom of the mounting plate 9. The output end of the grinding motor 12 is connected to the grinding wheel 8. Electric telescopic rods 11 are bolted to the top of the mounting plate 9. The top of the electric telescopic rods 11 is bolted to the bottom of the top plate 10.

[0020] Both the inner clamping plate 13 and the outer clamping plate 7 are arc-shaped, and the central axes of the inner clamping plate 13 and the outer clamping plate 7 are located in the same vertical plane.

[0021] The internal clamping plate 13 is positioned directly above the connecting rod 5, and the top end of the connecting rod 5 passes through the bottom end of the grinding table 1 and is connected to the bottom end of the internal clamping plate 13.

[0022] The outer side of the lead screw 14 is in contact with the inner wall of the positioning hole 17, and the inner wall of the positioning hole 17 is provided with an internal thread that matches the outer side of the lead screw 14.

[0023] The driving bevel gear 15 is disposed below the driven bevel gear 16, and the driving bevel gear 15 and the driven bevel gear 16 mesh with each other. The driven bevel gear 16 is symmetrical about the center of the driving bevel gear 15.

[0024] The grinding wheel 8 is positioned directly above the grinding table 1, and the diameter of the grinding wheel 8 is slightly smaller than the inner diameter of the grinding table 1.

[0025] The bottom ends of the inner clamping plate 13 and the outer clamping plate 7 are in contact with the bottom end of the interior of the grinding table 1, and the four inner clamping plates 13 and the four outer clamping plates 7 are symmetrical about the interior center of the grinding table 1.

[0026] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in the operation of this device, firstly, the device has a grinding table 1, which allows the rubber sealing ring to be ground to be placed inside the grinding table 1. Then, by utilizing the presence of the outer clamping plates 7, combined with the threaded connection between the lead screw 14 and the positioning hole 17, the user can manually rotate the lead screw 14 to allow the outer clamping plates 7 to move flexibly horizontally inside the grinding table 1. This allows for flexible adjustment of the horizontal position of the four outer clamping plates 7 inside the grinding table 1. By pressing the four outer clamping plates 7 against the outside of the rubber sealing ring, a restraining effect is achieved. Then, to further increase the stability of this device in the subsequent grinding process, the device has an internal clamping plate 13. By activating the servo motor 3, the active bevel gear 15 can rotate under the drive of the servo motor 3. Due to the meshing relationship between the active bevel gear 15 and the driven bevel gear 16, the rotation of the active bevel gear 15... This allows the four driven bevel gears 16 to rotate synchronously, thereby causing the four threaded rods 6 to rotate. By utilizing the rotation of the threaded rods 6 and the connection of the connecting rods 5, the threaded block 2 can stably move horizontally outside the threaded rods 6 during rotation, which in turn drives the internal clamping plates 13 to move synchronously. This allows the four internal clamping plates 13 to move synchronously inside the grinding table 1, performing an overall unfolding and retracting action. By using this, after the outer clamping plate 7 restricts the outside of the rubber sealing ring, the unfolding and retracting of the internal clamping plates 13 can contact the inside of the rubber sealing ring, achieving a further restriction effect from the inside of the rubber sealing ring. This improves the fixing and clamping effect of the device on the rubber sealing ring. Subsequently, through the extension and retraction of the electric telescopic rod 11 and the drive of the grinding motor 12, the grinding wheel 8 has good stability when grinding the rubber sealing ring.
