DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0033] Embodiment 1:

[0034] A bearing bushing processing polishing device with a limiting function comprises a polishing machine 1, a tabletop 2 and a polishing wheel 3, wherein the tabletop 2 is fixedly mounted on the top of the polishing machine 1, the driving end of the polishing machine 1 penetrates the top of the tabletop 2 and is fixedly connected to the bottom of the polishing wheel 3, bearing bushes 4 are arranged on both sides of the polishing wheel 3, a plurality of limiting frames 5 are arranged on one side of the bearing bushes 4, a sliding block 6 is fixedly connected to the bottom of the limiting frame 5, a sliding groove 7 used in conjunction with the sliding block 6 is provided on the top of the tabletop 2, and a limiting mechanism is arranged on the top of the limiting frame 5 to limit the bearing bush 4;

[0035] The adjusting mechanism is fixedly arranged on the limiting mechanism, and the position of the limiting mechanism can be adjusted according to the size of the bearing shell 4.

[0036] One implementation method of the present embodiment is: the limiting mechanism includes a threaded rod 8 threadedly connected to the top of the limiting frame 5, the top of the limiting frame 5 is provided with a threaded hole 20 used in conjunction with the threaded rod 8, the bottom of the threaded rod 8 is fixedly connected with a clamping block 9, the top of the threaded rod 8 is provided with a twisting block 10, and the surface of the twisting block 10 is provided with two anti-slip grooves 11.

[0037] In this embodiment, it is taken into consideration that when polishing the inner wall of the bearing 4, the position of the bearing 4 is easily offset, resulting in the inability of the polishing equipment to fully polish the inner wall of the bearing 4, thereby affecting the polishing effect. Therefore, by setting a limiting mechanism, it is possible to prevent the bearing 4 from being located at a specified position on the table 2, and then rotate several screwing blocks 10 in sequence. The screwing blocks 10 will drive the threaded rod 8 to rotate, and the threaded rod 8 will rotate in the threaded hole 20 and gradually move downward, while driving the clamping block 9 and the anti-slip pad 19 to move downward until the anti-slip pad 19 is in close contact with the top of the bearing 4. This can complete the limiting of the bearing 4, improve the stability of the bearing 4 during the polishing process, and thereby achieve the effect of improving the polishing effect.

[0038] Preferably, an anti-skid pad 19 is fixedly connected to the bottom of the pressing block 9, and the material of the anti-skid pad 19 is rubber.

[0039] In this embodiment, the anti-skid pad 19 is provided to provide a buffer for the contact between the pressing block 9 and the top of the bearing shell 4, thereby avoiding scratches on the surface of the bearing shell 4 caused by hard contact. At the same time, the rubber material can also improve the anti-skid effect.

[0040] Preferably, the sliding block 6 and the sliding slot 7 are both in a dovetail shape.

[0041] In this embodiment, by setting the shapes of the sliding block 6 and the sliding groove 7 to be dovetail-shaped, the engagement stability between the sliding block 6 and the sliding groove 7 can be improved, thereby improving the stability of the structure such as the limit frame 5.

[0042] Embodiment 2:

[0043] On the basis of Example 1, the limiting mechanism in this embodiment can limit the bearing 4 to improve the stability during the grinding process. However, considering the different sizes of the bearing 4, if the bearing 4 cannot be limited at the specified point, it will also affect the stability during polishing. The adjustment mechanism in this application includes a shell 12 fixedly connected to both sides of the limiting frame 5, and a moving block 13 is arranged inside the shell 12. The bottom of the moving block 13 is fixedly connected to a positioning rod 14. A positioning hole 15 for use with the positioning rod 14 is opened on the top of the table top 2. The top of the moving block 13 is fixedly connected to a pull rod 16. A linkage block 17 is arranged on one side of the limiting frame 5. The top of the pull rod 16 passes through the top of the shell 12 and is fixedly connected to the bottom of the linkage block 17.

[0044] In this embodiment, considering the different sizes of the bearing bush 4, if the bearing bush 4 cannot be restricted at the specified point, it will also affect the stability during polishing. Therefore, by setting an adjustment mechanism, the linkage block 17 can be pulled upward, and the linkage block 17 drives the pulling rod 16 and the moving block 13 to move upward, and the moving block 13 will drive the positioning rod 14 to leave the inside of the positioning hole 15. At this time, the position of the limit frame 5 can be adjusted along the trajectory of the sliding block 6 and the sliding groove 7. After reaching the appropriate position, the linkage block 17 is released, and the elastic force generated by the spring 18 will push the moving block 13 and the positioning rod 14 to move downward, so that the positioning rod 14 enters the corresponding positioning hole 15, completing the adjustment of the limit position, thereby improving the stability of the bearing bush 4 after the limit mechanism is limited;

[0045] The problem that the stability during polishing will be affected if the bearing bush 4 cannot be restricted at a designated point in consideration of the different sizes of the bearing bush 4 is solved.

[0046] Preferably, a spring 18 is sleeved on the surface of the pulling rod 16 , the top of the spring 18 is fixedly connected to the inner wall of the housing 12 , and the bottom of the spring 18 is fixedly connected to the top of the moving block 13 .

[0047] In this embodiment, the spring 18 is provided so that when the user releases the linkage block 17, the elastic force generated by the spring 18 can push the moving block 13 and the positioning rod 14 downward, so that the positioning rod 14 enters the corresponding positioning hole 15 to play a resetting role.

[0048] Preferably, there are a plurality of positioning holes 15 , which are evenly distributed on the top of the desktop 2 .

[0049] In this embodiment, by providing a plurality of positioning holes 15 , after the position of the limiting frame 5 is adjusted, the positioning rod 14 only needs to enter the corresponding positioning hole 15 to complete the adjustment of the limiting frame 5 , thereby improving the convenience of operation.

[0050] Working principle: After the bearing bush 4 is placed at a designated position on the table 2, several twisting blocks 10 are rotated in sequence, and the twisting blocks 10 drive the threaded rod 8 to rotate. The threaded rod 8 rotates in the threaded hole 20 and gradually moves downward, while driving the pressing block 9 and the anti-skid pad 19 to move downward until the anti-skid pad 19 is in close contact with the top of the bearing bush 4, thereby completing the position limitation of the bearing bush 4, improving the stability of the bearing bush 4 during the polishing process, and thus achieving the effect of improving the polishing effect;

[0051] Taking into account the different sizes of the bearing 4, if the bearing 4 cannot be restricted at the specified point, it will also affect the stability during polishing. Therefore, by setting up an adjustment mechanism, the linkage block 17 can be pulled upward, and the linkage block 17 drives the pulling rod 16 and the moving block 13 to move upward, and the moving block 13 will drive the positioning rod 14 to leave the positioning hole 15. At this time, the position of the limit frame 5 can be adjusted along the trajectory of the sliding block 6 and the sliding groove 7. After reaching the appropriate position, release the linkage block 17, and the elastic force generated by the spring 18 will push the moving block 13 and the positioning rod 14 to move downward, so that the positioning rod 14 enters the corresponding positioning hole 15, completing the adjustment of the limit position, thereby improving the stability of the limiting mechanism after limiting the bearing 4.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
