Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Specific examples are given below.

[0025] See also Figure 1-Figure 4The utility model provides a positioning structure for bearing processing, including a support table 1: support columns 2 are fixed at the four end corners of the lower end of the support table 1; an operating table 4 is fixed at the top of the support table 1; fixed frames 3 are fixed on both sides of the top of the support table 1; a plurality of arc-shaped clamping plates 7 are evenly arranged on the top of the operating table 4; a transmission assembly is arranged on the inner side of the operating table 4 and at positions corresponding to the arc-shaped clamping plates 7, and the transmission assembly includes a plurality of movable seats 9; a plurality of movable seats 9 are respectively arranged on the inner side of the operating table 4 and at positions below the arc-shaped clamping plates 7; the movable seat 9 is slidably connected to the operating table 4; a connecting block 8 is fixed on the top of the movable seat 9; the connecting block 8 is slidably connected to the operating table 4; the connecting block 8 is fixedly connected to the arc-shaped clamping plate 7; a driving assembly is arranged on the inner side of the operating table 4 and at positions corresponding to the movable seat 9. During operation, first place the bearing in the middle position of the operating table 4; then drive the movable seat 9 to move through the driving assembly, and when the movable seat 9 moves, the arc-shaped clamping plate 7 is driven to move at the same time through the connecting block 8, so that the multiple arc-shaped clamping plates 7 are moved in the direction of approaching each other, and then the bearing can be clamped and positioned through the multiple arc-shaped clamping plates 7. This step is designed by the matching structure of the driving assembly, the arc-shaped clamping plate 7, the connecting block 8 and the movable seat 9, so that the multiple movable seats 9 can be driven to move in the direction of approaching each other through the transmission assembly, so that when the movable seat 9 moves, the arc-shaped clamping plate 7 can be driven to move at the same time through the connecting block 8, and then the bearing can be clamped and fixed, which effectively improves the stability of the bearing positioning, reduces the shaking during the bearing processing, and improves the processing efficiency;

[0026] Further, such as Figure 2 and Figure 3As shown, the drive assembly includes multiple transmission screws 10; the multiple transmission screws 10 are respectively arranged on the inner side of the operating table 4 and at positions corresponding to the moving seat 9; the transmission screws 10 are rotatably connected to the operating table 4; the moving seat 9 is threadedly connected to the transmission screw 10; a transmission bevel gear 13 is fixed at one end of the multiple transmission screws 10 close to each other; a rotating shaft 14 is rotatably connected at a position on the inner side of the operating table 4 and corresponding to the transmission bevel gear 13; a driving bevel gear 12 is fixed to the top of the rotating shaft 14; the driving bevel gear 12 is meshed with the transmission bevel gear 13. During operation, when the rotating shaft 14 rotates, it drives the driving bevel gear 12 to rotate. When the driving bevel gear 12 rotates, it drives the driving screw 10 to rotate at the same time through the transmission bevel gear 13 meshing with it. When the transmission screw 10 rotates, it drives the moving seat 9 threadedly connected to it to move, so that when the moving seat 9 moves, it drives the arc clamping plate 7 to move through the connecting block 8, and then the bearing can be clamped and fixed by the arc clamping plate 7. This step is convenient for the matching structural design of the driving bevel gear 12, the transmission bevel gear 13 and the transmission screw 10, so that when the driving bevel gear 12 rotates, the transmission screw 10 can be driven to rotate through the transmission bevel gear 13, and then the arc clamping plate 7 can be driven to move simultaneously through the moving seat 9 and the connecting block 8.

[0027] Further, such as Figure 2 and Figure 3 As shown, a transmission worm gear 15 is fixed to the outer side of the lower end of the driving bevel gear 12; a transmission rod 17 is rotatably connected to the inner side of the operating table 4; a transmission worm 16 is fixed to the end of the transmission rod 17 close to the transmission worm gear 15; the transmission worm 16 is meshed with the transmission worm gear 15; a limit assembly is provided at the end of the transmission rod 17 away from the transmission worm 16. During operation, when the rotating shaft 14 needs to be rotated, the limit of the transmission rod 17 by the limit assembly is first canceled. Then, when the transmission rod 17 rotates, the transmission worm 16 can be driven to rotate. When the transmission worm 16 rotates, the rotating shaft 14 is driven to rotate through the transmission worm gear 15 meshed with it. In this step, when the transmission rod 17 rotates, the rotating shaft 14 can be driven to rotate simultaneously through the transmission worm 16 and the transmission worm gear 15, thereby effectively improving the convenience of operation.

[0028] like Figure 3 As shown, the end of the transmission rod 17 away from the transmission worm 16 extends to the outside of the operating table 4; a driving handle 18 is fixed to the end of the transmission rod 17 located outside the operating table 4. During operation, the driving handle 18 is rotated to drive the transmission rod 17 to rotate. This step facilitates the rotation of the transmission rod 17 by rotating the driving handle 18, improving the convenience of operation.

[0029] like Figure 3 and Figure 4As shown, the limit assembly includes a limit gear 19; the limit gear 19 is fixed to the transmission rod 17 at one end position on the inner side of the operating table 4 and close to the driving handle 18; the limit rack 20 is slidably connected to the inner side of the operating table 4 and at a position corresponding to the limit gear 19; the limit rack 20 is meshed with the limit gear 19; a connecting rod 21 is fixed to the side of the limit rack 20 away from the limit gear 19; a spring 22 is sleeved on the outside of one end of the connecting rod 21 close to the limit rack 20; one end of the spring 22 is fixedly connected to the limit rack 20; the other end of the spring 22 is fixedly connected to the operating table 4; a shift rod 23 is fixed to the end of the connecting rod 21 away from the limit gear 19; the shift rod 23 is slidably connected to the operating table 4; the end of the shift rod 23 away from the connecting rod 21 extends to the outside of the operating table 4. During operation, when it is necessary to cancel the limit of the transmission rod 17, first, by toggling the toggle lever 23, the toggle lever 23 drives the limit rack 20 to move through the connecting rod 21. When the limit rack 20 moves to disengage from the limit gear 19, the limit rack 20 cancels the limit on the limit gear 19, thereby enabling the transmission rod 17 to rotate. When it is necessary to limit the transmission rod 17, the toggle lever 23 is released. At this time, the limit rack 20 is pushed toward the limit gear 19 under the elastic action of the spring 22. When When the limit rack 20 moves to engage with the limit gear 19, the limit rack 20 completes the limiting of the limit gear 19, so that the transmission rod 17 cannot rotate. This step is achieved through the structural design of the limit assembly, so that the rotation limit of the transmission rod 17 can be controlled by the meshing connection between the limit rack 20 and the limit gear 19, thereby effectively avoiding the accidental rotation of the transmission rod 17 and causing loosening when clamping the bearing, thereby improving the stability of the bearing positioning and enhancing the practicality of the device.

[0030] like Figure 1 As shown, a hydraulic rod 5 is fixed at the middle position of the lower end of the fixing frame 3; the telescopic end of the hydraulic rod 5 is fixed to the lower pressure plate 6. During operation, after the bearing is positioned, the hydraulic rod 5 can be activated to drive the lower pressure plate 6 downward. The lower pressure plate 6 can then be used to punch the inner ring of the bearing into the inner ring of the bearing, thereby completing the bearing installation. This step effectively reduces the labor intensity of workers and improves work efficiency.

[0031] like Figure 2 and Figure 3 As shown, a rubber protective pad 11 is fixed to each side of the multiple arc-shaped clamping plates 7 where they are close to each other. During operation, when the arc-shaped clamping plates 7 clamp the bearing, they can act as a buffer. This step can effectively prevent the bearing from being damaged due to hard contact between the arc-shaped clamping plates 7 and the bearing when clamping.

[0032] Working principle: during operation, the bearing is first placed in the middle position of the operating table 4; then the moving seat 9 is driven to move by the driving assembly, and when the moving seat 9 moves, the arc-shaped clamping plate 7 is driven to move at the same time through the connecting block 8, so that the multiple arc-shaped clamping plates 7 are moved in the direction of approaching each other, and then the bearing can be clamped and positioned through the multiple arc-shaped clamping plates 7; when the rotating shaft 14 needs to be rotated, first the limit of the transmission rod 17 by the limit assembly is cancelled, and then when the transmission rod 17 rotates, it can drive the transmission worm 16 to rotate, and when the transmission worm 16 rotates, it drives the rotating shaft 14 to rotate through the transmission worm gear 15 meshing with it; when the rotating shaft 14 rotates, it drives the driving bevel gear 12 to rotate, and when the driving bevel gear 12 rotates, it drives the transmission screw 10 to rotate at the same time through the transmission bevel gear 13 meshing with it, and when the transmission screw 10 rotates, it drives the moving seat 9 threadedly connected to it to move, so that when the moving seat 9 moves, it drives the arc-shaped clamping plate 7 to move through the connecting block 8, and then it can be The arc-shaped clamping plate 7 clamps and fixes the bearing; by rotating the driving handle 18, the driving handle 18 can drive the transmission rod 17 to rotate; when it is necessary to cancel the limit of the transmission rod 17, first, by toggling the lever 23, the lever 23 drives the limit rack 20 to move through the connecting rod 21, and when the limit rack 20 moves to disengage from the limit gear 19, the limit rack 20 cancels the limit of the limit gear 19, thereby enabling the transmission rod 17 to rotate. When it is necessary to limit the transmission rod 17, the release lever 23 is released. Open the lever 23, and at this time, the limit rack 20 is pushed toward the limit gear 19 under the elastic action of the spring 22. When the limit rack 20 moves to engage with the limit gear 19, the limit rack 20 completes the limitation of the limit gear 19, so that the transmission rod 17 cannot rotate; when the bearing is positioned, the hydraulic rod 5 can be started to drive the lower pressure plate 6 to move downward, and then the inner ring of the bearing can be punched into the inner ring of the bearing through the lower pressure plate 6, thereby completing the installation of the bearing.
