Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, in particular to a polishing machine for inner and outer rings of bearings. Background Art

[0002] The polishing of the inner and outer rings of bearings is a surface treatment process aimed at obtaining a smoother and flatter surface by removing minute surface defects and burrs. This process is crucial for enhancing the operating performance of bearings as it helps reduce the friction coefficient, lower the wear rate, and promote the uniform distribution of lubricating oil. The polishing process typically uses specialized polishing equipment and fine polishing materials such as abrasive paste or polishing cloth to achieve high-precision surface treatment. High-quality polishing not only improves the appearance of the bearings but also effectively extends their service life, ensuring stable operation of the bearings under high-speed or heavy-load conditions.

[0003] In the prior art, to ensure the efficiency of polishing the inner and outer rings of bearings, a whole batch of bearing rings are often put into a container for polishing together. However, due to the excessive number of bearing rings in such polishing, although the bearing rings can be polished, during the polishing process, the bearing rings collide with each other, resulting in obvious knocks on the bearing rings.

[0004] Therefore, a polishing machine for inner and outer rings of bearings is proposed to solve or alleviate the above problems. Content of the Utility Model

A partition is fixedly connected inside the lower housing to divide the polishing space into several independent spaces. A plurality of through grooves communicating with each independent space are opened on the upper housing, and the through grooves are provided to be openable and closable. A small amount of abrasive is always retained in the independent space, and when the maximum abrasive filling amount in the independent space is less than the volume of the independent space.

[0008] Preferably, a sealing plate is rotatably connected in the through groove, and one end of the sealing plate away from its rotation connection is fitted with the inner wall of the through groove.

[0026] A polishing machine for the inner and outer rings of a bearing, such as Figure 1 and 2As shown in the figure, it includes a support frame 1, a mounting base 2, a driving motor 3 fixedly connected to its top surface, a connecting seat 6 fixedly connected to the side wall of the mounting base 2, an L-shaped connecting plate 7 fixedly connected to the connecting seat 6, a lower housing 11 and an upper housing 12 hinged thereto. The mounting base 2 is fixedly connected to the support frame 1, a driving wheel 4 fixedly connected to the output shaft of the driving motor 3, a driven wheel 10 rotatably connected to the connecting plate 7, and a transmission belt 5 drivingly connecting the driving wheel 4 and the driven wheel 10. The upper housing 12 and the lower housing 11 form a cylindrical structure. One end of the lower housing 11 is coaxially drivingly connected to the driven wheel 10. A rotating shaft 8 is fixedly connected to the connecting plate 7, and a bearing 9 is sleeved on the rotating shaft 8. The outer ring of the bearing 9 is coaxially fixedly connected to the end face of the lower housing 11. The lower housing 11 and the rotating shaft 8 are kept in a rotating state through the bearing 9.

[0027] A lower connecting strip 13 and an upper connecting strip 15 are respectively fixedly connected to the lower housing 11 and the upper housing 12 away from the rotating connection. The upper connecting strip 15 and the lower connecting strip 13 are clamped by bolts and nuts. When the upper housing 12 and the lower housing 11 are closed, the upper connecting strip 15 and the lower connecting strip 13 are connected face to face, and a polishing space is formed therebetween. A partition plate 14 that divides the polishing space into several independent spaces is fixedly connected inside the lower housing 11. A plurality of through grooves 16 communicating with each independent space are formed in the upper housing 12. The through grooves 16 can be opened and closed. A sealing plate 17 is rotatably connected in the through grooves 16. One end of the sealing plate 17 away from its rotating connection is fitted with the inner wall of the through groove 16. A small amount of abrasive is always retained in the independent space, and when the maximum abrasive filling amount in the independent space is less than the volume of the independent space.

[0028] When the present utility model actually needs to work, each bearing 9 ring is separately placed into a single independent space. At this time, since there is a part of abrasive in the independent space itself, the bearing 9 ring is prevented from directly colliding with the inner wall of the independent space. Then, the upper cover 12 and the lower cover 11 are closed, and the upper connecting bar 15 and the lower connecting bar 13 are clamped through the bolt and nut structure to prevent the upper cover 12 and the lower cover 11 from separating. Then, abrasive is further injected through the through groove 16 so that the abrasive submerges the bearing 9 ring but does not fill the independent space. Then, the sealing plate 17 is closed to seal the through groove 16. Then, the driving motor 3 is started to drive the driving wheel 4 to rotate, so that the driving wheel 4 and the driven wheel 10 drive the driven wheel 10 to rotate. When the driven wheel 10 rotates, it can drive the lower cover 11 to rotate, and finally the upper cover 12 and the lower cover 11 can rotate, so that the abrasive polishes the bearing 9 ring in the independent space. After the polishing is completed, only the work of the driving motor 3 needs to be stopped. Most of the abrasive is poured out from the through groove 16 by opening the sealing plate 17, and only a part is retained. Then, the connection of the bolt and nut is released, the upper cover 12 and the lower cover 11 are opened, and the bearing 9 ring is taken out, and the next batch of bearings 9 rings to be polished can be replaced. This polishing method can avoid the collision of each bearing 9 ring and can also properly complete the polishing action.

[0029] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
