DETAILED DESCRIPTION

[0018] 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.

[0019] Example 1

[0020] See also Figures 1 to 4, which is the first embodiment of the utility model, and this embodiment provides a technical solution: a polishing device for bearing processing, comprising a base 1 and a polishing structure arranged above the base 1, a push plate 3 is slidably arranged at the inner bottom end of the base 1, and two bearing clamping structures are symmetrically arranged on the top of the push plate 3, and side sliders 32 are welded and fixed to the two side surfaces of the push plate 3, and rectangular slide grooves 11 are opened on the inner walls of both sides of the base 1, and rectangular slides 33 are welded and fixed at the ends of the side slides 32, and the rectangular slides 33 are slidably located in the rectangular slide grooves 11, and blocking and positioning structures are arranged on both sides of the base 1, and the blocking and positioning structures include an outer card seat 51, a strip slide 52, a strip connecting block 54 and a positioning block 55, and the positioning block 55 is arranged inside the rectangular slide groove 11. On the side, the rectangular slider 33 can be blocked during the subsequent polishing process of pushing the bearing forward to prevent the bearing from being pushed forward too much and causing excessive polishing. A strip connecting block 54 is welded and fixed on one side of the positioning block 55. Both side surfaces of the base 1 are provided with strip slideways 52 corresponding to the strip connecting block 54. The sliding of the strip connecting block 54 is located in the strip slideway 52. ​​The outer card seat 51 is arranged on the outer side surface of the base 1. An inner slide groove 56 is provided inside the outer card seat 51. A spring 57 and an inner slide block 59 are arranged in the inner slide groove 56. A connecting rod 58 is fixed on one side of the inner slide block 59, and one end of the connecting rod 58 passes through the outer side of the outer card seat 51 and is fixedly connected to the strip connecting block 54. The positioning block 55 can be adjusted by the outer card seat 51 in the later stage. The position of the outer holder 51 can be met with different bearing processing requirements. The blocking and positioning structure also includes a limiting block 510 and a limiting slot 53. Two limiting blocks 510 are symmetrically welded on one side surface of the outer holder 51. A plurality of limiting slots 53 corresponding to the limiting blocks 510 are evenly provided on the side surfaces of the base 1 relative to the two sides of the strip slide 52. The limiting block 510 is embedded in one of the limiting slots 53 to limit the outer holder 51 during daily use and ensure the position stability of the positioning block 55. When the bearing is clamped above the push plate 3 by the two bearing clamping structures, the operator will push the push plate 3 toward the polishing wheel 23, causing the bearing to contact with the polishing wheel 23 for polishing. During the pushing process, under the blocking effect of the positioning block 55, the rectangular The slider 33 will be blocked by the positioning block 55 to avoid excessive forward pushing, thereby avoiding the bearing from being pushed forward too much and causing excessive polishing. At the same time, the position of the positioning block 55 can be flexibly adjusted according to different processing requirements. When adjusting, it is only necessary to pull the outer card seat 51 to the side so that the spring 57 is compressed, causing the outer card seat 51 to move sideways smoothly and make the limiting card block 510 move out of the limiting card slot 53. At this time, the limit on the outer card seat 51 can be released, and then the outer card seat 51 can be slid back and forth on the side of the base 1, so that the positioning block 55 can slide in the rectangular slide groove 11 to achieve the adjustment of the position of the positioning block 55. When the positioning block 55 is adjusted to a suitable position, it is only necessary to release the outer card seat 51 so that the spring 57 pushes the outer card seat 51 back.The limit block 510 can be inserted into the limit slot 53 at other positions, so that the outer card seat 51 and the positioning block 55 can be limited again, and the stable limit after the position adjustment of the positioning block 55 is completed.

[0021] One end of the spring 57 abuts against the side surface of the inner slide block 59 , and the other end of the spring 57 abuts against the inner wall of the inner slide groove 56 , thereby ensuring the installation stability of the spring 57 .

[0022] Among them, the upper and lower surfaces of the outer card holder 51 are both welded and fixed with shifting bars, and the cross-section of the shifting bars is rectangular, which is convenient for the subsequent pulling of the outer card holder 51.

[0023] Among them, the bearing clamping structure includes a threaded rod 41, a clamping block 42 and an anti-skid clamping pad 43. Two vertical plates 31 are symmetrically fixed on the top of the push plate 3. The threaded rod 41 spiral ring passes through the top of the vertical plate 31. The clamping block 42 is rotatably installed on the inner end of the threaded rod 41, and the anti-skid clamping pad 43 is installed on the surface of the clamping block 42. The bearing to be polished can be placed between the two clamping blocks 42, and then the threaded rod 41 is rotated to make the clamping block 42 move toward the top center of the push plate 3 until the two clamping blocks 42 can clamp and fix the bearing, and then the subsequent polishing operation can be carried out, and the anti-skid clamping pad 43 plays an anti-skid role to ensure the clamping stability of the bearing.

[0024] Among them, the polishing structure includes a motor 21, a base shaft 22 and a polishing wheel 23. The base shaft 22 is rotatably installed on the inner side of the base 1, and the polishing wheel 23 is installed at the center of the base shaft 22. The motor 21 is fixed on the right side surface of the base 1, and the output end of the motor 21 passes through the inner side of the base 1 and is connected to the base shaft 22, so that after the motor 21 is started, the base shaft 22 and the polishing wheel 23 can be driven to rotate. Subsequently, the bearing to be polished only needs to be pushed toward the polishing wheel 23 for grinding and polishing.

[0026] See also Figures 1 to 5 , which is the second embodiment of the utility model. This embodiment is based on the previous embodiment, and the difference is that the disassembly and assembly structure can be provided to facilitate the disassembly and assembly and replacement of the anti-skid clamping pad 43 when it is damaged in the later stage.

[0027] Specifically, a disassembly structure is also provided between the anti-skid clamping pad 43 and the clamping block 42, and the disassembly structure includes a rubber plug-in block 431, a triangular side block 432, a slot 421 and a side card slot 422. Two integrated rubber plug-ins 431 are provided on one side surface of the anti-skid clamping pad 43, and a triangular side block 432 is provided on one side surface of the rubber plug-in block 431. Two slots 421 for inserting the rubber plug-in blocks 431 are provided on the surface of the clamping block 42, and a side card slot 422 corresponding to the triangular side block 432 is provided on one side inner wall of the slot 421. The triangular side block 432 is embedded in the side card slot 422 to achieve stable installation of the anti-skid clamping pad 43. If the anti-skid clamping pad 43 is to be removed and replaced later, it is only necessary to pull the anti-skid clamping pad 43 sideways with force, so that the rubber plug-in block 431 and the triangular side block 432 are deformed by tension and pulled out of the slot 421, and the anti-skid clamping pad 43 can be easily removed and replaced.

[0028] The rubber insert 431 and the triangular side block 432 are an integrated structure, both of which are made of rubber material and will undergo elastic deformation when squeezed. A rectangular cavity is provided in the rubber insert 431, so that the triangular side block 432 has sufficient deformation space when squeezed.
