[0030] 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.

[0031] Reference Figure 1 - Figure 2 The utility model provides an embodiment: a sleeve polishing mechanism, including a base 1, a polishing assembly 4 is arranged on the upper surface of the base 1, the polishing assembly 4 can grind and polish the inner wall and the outer wall of the sleeve at the same time, thereby improving the processing efficiency, a driving assembly 3 is arranged on the lower surface of the base 1, a support plate 2 is fixedly connected to the left side of the upper surface of the base 1 adjacent to the polishing assembly 4, a rectangular groove 7 is arranged on the left surface of the support plate 2, a fixing assembly 5 is arranged on the top of the support plate 2, a limiting assembly 6 is arranged on the front end of the polishing assembly 4, the polishing assembly 4 includes a rotating column 41, the rotating column 41 passes through and is rotatably connected to the upper surface of the base 1, a turntable 43 is rotatably connected to the inner wall of the rotating column 41, and a motor 31 is fixedly connected to the lower surface of the rotating column 41. When the motor 31 is not started, the rotating column 41 will not rotate, thereby ensuring the stability of the coordination between the structures. A ring 42 is fixedly connected to the outer wall of the top of the turntable 43.

[0032] Reference Figure 1 , Figure 4 The fixing assembly 5 includes a threaded rod 53. The threaded rod 53 is a prior art and has a certain self-locking property up and down, and will not rotate by itself, thereby ensuring the stability of the fixation. The threaded rod 53 penetrates and is rotatably connected to the upper surface of the support plate 2. The outer wall of the threaded rod 53 is threadedly connected to a connecting plate 51. The right end of the connecting plate 51 is slidably connected to the inner wall of the rectangular groove 7. The left surface of the connecting plate 51 is fixedly connected to a fixing plate 52. The lower surface of the fixing plate 52 is made of rubber. The rubber material can increase the friction between the fixing plate 52 and the shaft sleeve, so that the rotation speed of the shaft sleeve is different from the rotation speed of the turntable 43, thereby ensuring the comprehensiveness of the grinding and polishing.

[0033] Reference Figure 1 - Figure 2 The driving assembly 3 includes a support frame 32, which is fixedly connected to the lower surface of the base 1. The upper surface of the support frame 32 is fixedly connected to a motor 31. The motor 31 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The upper surface of the motor 31 is fixedly connected to the lower surface of the rotating column 41.

[0034] Reference Figure 1 - Figure 3The limiting assembly 6 includes a button 61, which is longer than the limiting column 62, to ensure that the limiting column 62 can smoothly detach from the inner wall of the groove. The button 61 penetrates and slides to be connected to the front end of the upper surface of the rotating column 41. The lower surface of the button 61 is fixedly connected with a connecting plate 2 63, and the connecting plate 2 63 is slidably connected to the inner wall of the front end of the rotating column 41. The rear end of the upper surface of the connecting plate 2 63 is fixedly connected to the limiting column 62. The limiting column 62 penetrates and slides to be connected to the front end of the upper surface of the rotating column 41 near the rear side of the button 61. The lower surface of the connecting plate 2 63 is fixedly connected with a spring 64. The spring 64 itself has a certain elasticity. It always pushes the connecting plate 2 63 upward through its own elasticity to ensure that the limiting column 62 always contacts the inner wall of the groove when the button 61 is changed, thereby ensuring the stability of the limit. The bottom end of the spring 64 is fixedly connected to the inner wall of the front end of the rotating column 41. The lower surface of the ring 42 is provided with a groove and there are multiple groups of grooves. The upper surface of the limiting column 62 contacts the inner wall of the groove.

[0035] Reference Figure 1 - Figure 2 The upper surface of the turntable 43 is provided with a through slot 1 46, and the upper surface of the through slot 1 46 is provided with a through slot 2 47 adjacent to the rear side of the through slot 1 46. The through slot 1 46 and the through slot 2 47 have a certain amplitude, and when the turntable 43 is rotated, the plurality of slide bars 49 will respectively follow the amplitude of the through slot 1 46 and the through slot 2 47 and respectively contact the inner wall and the outer wall of the shaft sleeve, and the inner wall of the through slot 1 46 is slidably connected with the slide bar 49, and the outer wall of the top of the slide bar 49 is rotatably connected with the grinding column 44, and the grinding column 44 is The surface is rotatably connected with ball bearings 45. During the grinding process, some sleeves may be at the same height as the grinding column 44. At this time, the fixed plate 52 may contact the grinding column 44. The ball bearings 45 can reduce friction. There are multiple groups of slide bars 49, and the multiple groups of slide bars 49 are slidably connected to the inner wall of the through groove 2 47. The inner wall of the rotating column 41 is provided with a rectangular groove 1 48. The lower surface of the slide bar 49 is slidably connected to the inner wall of the rectangular groove 1 48. The rectangular groove 1 48 ensures that the slide bar 49 always moves in a horizontal state.

[0036] Working principle: When in use, place the sleeve on the upper surface of the turntable 43. It is best to apply some lubricating oil on the lower surface of the sleeve to reduce friction. Suddenly, you only need to press the button 61 downward. At this time, the button 61 will drive the limit column 62 to move downward through the connecting plate 2 63 and squeeze the spring 64 until the limit column 62 is completely separated from the inner wall of the groove. At this time, the ring 42 can be rotated, and the ring 42 will drive the turntable 43 to rotate together. At this time, multiple groups of slide rods 49 will move respectively following the arc of the through groove 1 46 and the through groove 2 47, so that multiple groups of slide rods 49 will respectively drive multiple groups of grinding columns 44 to contact the inner and outer walls of the sleeve. At this time, release the button 61, and the spring 64 will push the connecting plate 2 63 to move in the opposite direction through its own elasticity, and the connecting plate 2 63 will push the limit column 62 to move in the opposite direction and insert into the inner wall of the groove.

[0037] Then, the threaded rod 53 is rotated, and the threaded rod 53 will drive the connecting plate 51 to move downward, and the connecting plate 51 will drive the fixing plate 52 to move downward until the fixing plate 52 contacts the upper surface of the shaft sleeve and the lower surface of the fixing plate 52 is squeezed and deformed. At this time, the motor 31 can be started, and the motor 31 will drive the rotating column 41 to rotate, and the rotating column 41 will drive the grinding column 44 to rotate through the turntable 43 to grind the inner and outer walls of the shaft sleeve at the same time. In this process, because the lower surface of the shaft sleeve is in direct contact with the upper surface of the turntable 43, it will also rotate accordingly. At that time, under the action of the lubricating oil at its bottom and the fixing plate 52 in contact with the upper surface, the rotation speed of the shaft sleeve will be reduced, so that it can be ensured that the grinding column 44 can fully grind the shaft sleeve, and the ball 45 is provided to prevent the fixing plate 52 from directly contacting the grinding column 44 and being worn, thereby increasing the service life of the fixing plate 52.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
