[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 This utility model provides a technical solution: a polishing device for the outer ring of a needle roller bearing, comprising: an operating table 1 and a needle roller bearing inner ring limiting assembly 27. A first motor 2 is fixedly connected to the lower surface of the operating table 1, and a first rotating shaft 3 is fixedly connected to the output end of the first motor 2. The side surface of the first rotating shaft 3 is rotatably connected to the operating table 1. A rotating plate 4 is fixedly connected to the upper surface of the first rotating shaft 3. A spherical groove 5 is provided inside the rotating plate 4, and a ball bearing 6 is provided on the inner surface of the spherical groove 5. A circular track 7 is provided on the upper surface of the operating table 1. A turntable 28 is fixedly connected to the upper surface of the rotating plate 4, and a placement plate 29 is fixedly connected to the upper surface of the turntable 28. The first motor 2 is started to drive the first rotating shaft 27. A rotating shaft 3 and a rotating plate 4 rotate, and the balls 6 in the spherical groove 5 move on the circular track 7. The two sets of placement plates 29 on the rotating plate 4 interchange positions, which can perform semi-automatic feeding. At the same time, while polishing one set of needle roller bearings, the operator can simultaneously perform the unloading and loading operations of another set of needle roller bearings. There is no need to stop the machine to load and unload after each set is polished, which saves the time of loading and unloading. The bottom inner wall of the groove 8 is fixedly connected to the battery 10. The second motor 11 and the turntable 28 are both electrically connected to the battery 10. The placement plate 29 has a groove 8 inside, and the inner surface of the groove 8 is fixedly connected to the fixing plate 9. The fixing plate 9 supports the second motor 11.

[0026] The needle roller bearing inner ring limiting assembly 27 includes a second motor 11, a bidirectional threaded screw 12, a first slider 13, a connecting plate 14, a limiting plate 15, and an anti-slip pad 16. The output end of the second motor 11 is fixedly connected to the bidirectional threaded screw 12. The side surface of the bidirectional threaded screw 12 is threadedly connected to the first slider 13. The end of the connecting plate 14 away from the limiting plate 15 is fixedly connected to the first slider 13, and the end of the connecting plate 14 away from the first slider 13 is fixedly connected to the limiting plate 15. The inner surface of the anti-slip pad 16 is fixedly connected to the limiting plate 15. Starting the second motor 11 drives the bidirectional threaded screw 12... 2. Rotation of the two first sliders 13, connecting plate 14, limiting plate 15, and anti-slip pad 16 on the bidirectional threaded screw 12 can limit the inner rings of needle roller bearings with different inner diameters by moving in opposite directions to both ends. The lower surface of the limiting plate 15 is slidably connected to the placement plate 29, and the lower surface of the anti-slip pad 16 is slidably connected to the placement plate 29. There are two turntables 28 and two placement plates 29, which are symmetrically distributed. A baffle 17 is fixedly connected to the upper surface of the operating table 1. When one set of needle roller bearings is polished and another set of needle roller bearings is loaded and unloaded, the baffle 17 does not affect the simultaneous operation of the two operations.

[0027] The operating table 1 is equipped with an electric slide rail 18. A second slider 19 is slidably connected to the inner surface of the electric slide rail 18. A fixed frame 20 is fixedly connected to the upper surface of the second slider 19. By activating the electric slide rail 18, the second slider 19, the fixed frame 20, and the polishing block 25 on the fixed frame 20 can be moved, thus adjusting the position of the polishing block 25. A cylinder 21 is fixedly connected to the upper surface of the fixed frame 20. A fixed box 22 is fixedly connected to the output end of the cylinder 21. By activating the cylinder 21, the fixed box 22 can be moved, thus adjusting the height of the polishing block 25 on the fixed box 22. The bottom inner wall of the fixed box 22 is fixedly connected to a third motor 23. The output end of the third motor 23 is fixedly connected to a second rotating shaft 24. The lower surface of the second rotating shaft 24 is fixedly connected to a polishing block 25. Through the turntable 28 and the third motor 23, the third motor 23 drives the second rotating shaft 24 and the polishing block 25 to rotate, which can polish the outer ring of the needle roller bearing. The side surface of the second rotating shaft 24 is rotatably connected to the fixed box 22. The upper surface of the operating table 1 is fixedly connected to a vacuum cleaner 26. During the polishing process, the vacuum cleaner 26 can be turned on to collect the impurities and dust generated during polishing.

[0028] Working principle: The needle roller bearings to be polished are placed on the outside of the two anti-slip pads 16 on the placement plate 29. The second motor 11 is started, driving the bidirectional threaded screw 12 to rotate. The two first sliders 13, connecting plate 14, limiting plate 15, and anti-slip pads 16 on the bidirectional threaded screw 12 move in opposite directions to limit the inner rings of needle roller bearings with different inner diameters. The first motor 2 is started, driving the first rotating shaft 3 and rotating plate 4 to rotate. The balls 6 in the spherical groove 5 move on the circular track 7, causing the limited needle roller bearings to rotate to the polishing block 25 for polishing. While polishing, the above operation is repeated. The operator can then limit the next set of needle roller bearings. After the needle roller bearings near the polishing block 25 are polished, the first motor 2 is started, driving the first rotating shaft 3 and rotating plate 4 to rotate the next set of needle roller bearings to the polishing block 25 for polishing. This process is repeated for each set of needle roller bearings. Simultaneously, the second motor 11 on one side is started after the previous set of polishing is completed. The output end of the second motor 11 rotates, driving the bidirectional threaded screw 12 to rotate. The first slider 13, connecting plate 14, limiting plate 15 and anti-slip pad 16 on the bidirectional threaded screw 12 move in opposite directions toward the center and no longer limit the needle roller bearings. After that, the operator can unload the needle roller bearings that have been polished in the previous set. After unloading, the above operation is repeated to load another set of needle roller bearings that need to be polished. While polishing one set of needle roller bearings, the device can simultaneously perform the unloading and loading operations of another set of needle roller bearings, realizing the continuity of the production process. It is not necessary to stop the machine for loading and unloading after each set of polishing, saving loading and unloading time, improving the overall production efficiency, and can limit the needle roller bearings with different inner diameters. It is not necessary to equip each specification of needle roller bearing with different polishing equipment, reducing equipment procurement costs and production space occupation.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
