Technical Field
[0001] This utility model relates to the field of bearing assembly technology, and in particular to a bearing assembly positioning and protection device. Background Technology
[0002] Bearings are precision core moving parts in mechanical systems. Their essential function is to achieve efficient transmission and precise control of mechanical motion through the scientific management of friction. They come in many types and are mainly composed of inner and outer rings, rolling elements, cages, and seals. The core components are the inner and outer rings and the rolling elements. During production and assembly, the inner and outer rings and the rolling elements need to be properly fitted and adapted.
[0003] The existing method for assembling bearing inner and outer rings and rolling elements involves first placing the inner ring on one side inside the outer ring, then placing multiple rolling elements into the larger gap between the inner and outer rings, holding the inner ring still, and using external tools to position and abut against the opposite sides of the outer ring. This presses the rolling elements into the grooves on the opposite sides of the inner and outer rings. The position of each rolling element in the groove is then adjusted evenly. However, during operation, it has been found that because the other set of opposite sides of the outer ring is not subjected to compressive force, it is difficult to control the bearing by relying solely on the pressure of one set of opposite sides. This leads to slippage of the outer ring, which in turn changes the force between the inner and outer rings and the rolling elements, causing the rolling element insertion operation to fail and reducing the efficiency of bearing processing and assembly.
[0004] Therefore, in the existing assembly method of bearing inner and outer rings and rolling elements, it is difficult to control the pressure on the opposite surfaces of a set of outer rings during operation, which makes the outer rings prone to slippage. The force between the inner and outer rings and the rolling elements changes, resulting in the failure of the rolling element insertion operation, thereby reducing the efficiency of bearing processing and assembly. A bearing assembly device with enhanced positioning force protection can be designed. Utility Model Content

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] Please see Figures 1-5 This utility model provides an embodiment of a bearing assembly positioning and protection device, including a circumferential seat 1; and a positioning mechanism. A fixing ring 2 is fixedly connected to the upper end of the circumferential seat 1, and a positioning mechanism is provided on the fixing ring 2. The positioning mechanism is used to position and fix the outer ring of the bearing placed on the circumferential seat 1. A through groove 4 is opened in the middle of the circumferential seat 1, and a support frame 6 is movably arranged through the through groove 4. A movable seat 5 is provided at the bottom of the circumferential seat 1, and the support frame 6 is fixedly connected to the upper end of the movable seat 5. A control and adjustment mechanism is provided at the bottom of the circumferential seat 1, and the control and adjustment mechanism is used to adjust the position of the support frame 6 to squeeze the inner ring.
[0025] The positioning mechanism includes an internal gear ring 301, gears 302, rectangular frames 303, a positioning drive motor 304, and an arc-shaped positioning block 305. The internal gear ring 301 is movably mounted on the inner side of the fixed ring 2. Four gears 302 are rotatably connected in a circular array at the upper end of the circumferential seat 1, and all four gears 302 mesh with the internal gear ring 301. Four rectangular frames 303 are arranged in a circular array at the upper end of the fixed ring 2, sleeved on the outside of each gear 302. Each rectangular frame 303 has teeth on one inner side that mesh with the gear 302. An arc-shaped positioning block 305 is fixedly connected to one side of each of the four rectangular frames 303 facing the center of the circumferential seat 1. The positioning drive motor 304 is fixedly connected to the bottom of the circumferential seat 1, and the output shaft of the positioning drive motor 304 is fixedly connected to one of the gears 302. The positioning drive motor 304 is used to drive the corresponding gear 302 to rotate. The inner and outer rings of the bearing are placed together at the upper center of the circumferential seat 1. The positioning mechanism is used to start the positioning drive motor 304 to drive the corresponding gear 302 to rotate. The gear 302 drives the internal gear ring 301 to rotate, so that the four gears 302 rotate synchronously and push the corresponding rectangular frame 303 to move. The four arc-shaped positioning blocks 305 abut against the outer ring of the bearing to position and fix it for protection. Then, the control and adjustment mechanism is used to lift the moving seat 5 and move the support frame 6 to the inside of the inner ring of the bearing. Then, the support frame 6 is used to drive the inner ring of the bearing to move to one side a suitable distance. Then, the rolling element is added to the side with a larger gap between the inner and outer rings of the bearing. Finally, the support frame 6 is used to move horizontally in the opposite direction to the original position to embed the rolling element into the groove between the inner and outer rings of the bearing.
[0026] Please see Figure 1 , Figure 3 and Figure 4 In this embodiment, four arc-shaped combination plates 10 are distributed on the upper ends of the fixed ring 2 and the internal toothed ring 301, and each arc-shaped combination plate 10 is fixedly connected to the fixed ring 2. The arc-shaped combination plates 10 are used to restrict the internal toothed ring 301 and prevent it from jumping upward. A gap is provided between two adjacent arc-shaped combination plates 10 for the rectangular frame 303 to move together. An arc-shaped limiting plate 11 is fixedly connected between the upper gaps of two adjacent arc-shaped combination plates 10. The gap between two adjacent arc-shaped combination plates 10 allows the rectangular frame 303 to move freely. The arc-shaped limiting plate 11 restricts the rectangular frame 303 from jumping upward. An extension platform 8 is fixedly connected to one side of the circumferential seat 1. A controller 9 is fixedly connected to the upper end of the extension platform 8. The positioning drive motor 304 is electrically connected to the controller 9. Rubber pads 12 are fixedly connected to the side of the four arc-shaped positioning blocks 305 facing the center of the circumferential seat 1. The controller 9 is used to control the operation of various electrical facilities. The rubber pads 12 can avoid excessive pressure on the outside of the bearing and cause damage.
[0027] Please see Figure 2 and Figure 5In this embodiment, the control and adjustment mechanism includes a lifting component and a horizontal movement component. The lifting component is used to adjust the height of the support frame 6, and the horizontal movement component is used to adjust the left and right positions of the support frame 6. Dividing the control and adjustment mechanism into a lifting component and a horizontal movement component allows for independent adjustment of the height and horizontal position of the support frame 6. The horizontal movement component includes an N-shaped plate 721, a threaded rod 722, and a moving drive motor 723. An N-shaped plate 721 is provided below the circumferential seat 1. A threaded rod 722 is rotatably connected between the inner sides of the N-shaped plate 721. The moving seat 5 is threadedly connected to the outer side of the threaded rod 722. A moving drive motor 723, which is electrically connected to the controller 9, is fixedly connected to one side of the N-shaped plate 721. The output shaft of the moving drive motor 723 is connected to the threaded rod 722. The support frame 6 is fixedly connected to the support 722. The moving drive motor 723 drives the threaded rod 722 to rotate. When the moving drive motor 723 is started, the threaded rod 722 rotates, and the threaded rod 722 drives the moving seat 5 to move, so as to facilitate the adjustment of the horizontal position of the support frame 6. The lifting assembly includes a lifting drive cylinder 711 and a support seat 712. Two lifting drive cylinders 711 are fixedly connected to the bottom of the circumferential seat 1. The output ends of the two lifting drive cylinders 711 are fixedly connected to the support seat 712. The lifting drive cylinders 711 are used to control and adjust the height position of the support seat 712. The support seat 712 and the N-shaped plate 721 are fixedly connected. When the lifting drive cylinders 711 are started, the support seat 712 is moved, thereby adjusting the height position of the horizontal moving assembly, and then adjusting the height of the support frame 6.
[0028] During operation, the inner and outer rings of the bearing are placed together at the upper center of the circumferential seat 1. The positioning mechanism is used to start the positioning drive motor 304, which drives the corresponding gear 302 to rotate. The gear 302 drives the internal gear ring 301 to rotate, so that the four gears 302 rotate synchronously and push the corresponding rectangular frame 303 to move. The four arc-shaped positioning blocks 305 abut against the outer ring of the bearing to position and fix it for protection. Then, the control and adjustment mechanism is used to start the lifting drive cylinder 711 to push the support seat 712 to move, thereby adjusting the height of the horizontal moving component and raising the moving seat 5. The support frame 6 moves to the inside of the inner ring of the bearing. Then, the moving drive motor 723 is started to drive the threaded rod 722 to rotate. The threaded rod 722 drives the moving seat 5 to move. The support frame 6 is adjusted to move the inner ring of the bearing to one side a suitable distance. The rolling element is added to the side with a larger gap between the inner and outer rings of the bearing. Finally, the support frame 6 is moved horizontally in the opposite direction to the original position to embed the rolling element into the groove between the inner and outer rings of the bearing. Finally, the position of the support frame 6 is lowered to facilitate the removal of the assembled bearing.
[0029] Through the above steps, the device uses a positioning mechanism with four arc-shaped positioning blocks 305 to position and protect the outer ring of the bearing, preventing it from slipping during compression. Combined with the support frame 6 under the control of the adjustment mechanism, the inner ring of the bearing is pushed, effectively embedding the rolling elements into the groove between the inner and outer rings, thus completing the bearing assembly. The operation is stable and safe, the positions of the inner and outer rings are relatively stable, the force is relatively uniform, and slippage is less likely. This facilitates rapid bearing assembly and improves work efficiency. It addresses the problem of existing bearing assembly methods where it is difficult to control the pressure on the opposing surfaces of a set of outer rings during operation, leading to slippage of the outer ring, changes in the force between the inner and outer rings and the rolling elements, and ultimately, failure of the rolling element embedding operation, thus reducing the efficiency of bearing processing and assembly.
