[0002] Bearings, as core components in mechanical transmission systems, are mainly used to support rotating shafts or other moving parts, reduce frictional losses during movement, and ensure the rotational accuracy and motion stability of the parts. They are widely used in automobiles, machine tools, construction machinery, aerospace and other fields.

[0003] Four-point ball contact bearings, due to their special raceway design, can simultaneously withstand radial loads and bidirectional axial loads. They also have a large contact angle and a high limiting speed, making them widely used in precision transmission scenarios that bear combined loads. The assembly process requires the inner or outer ring of the bearing to be precisely pressed into the preset position of the bearing housing, shaft, or other workpieces. It is also necessary to ensure the coaxiality of the bearing and the workpiece to avoid assembly deviations that could lead to accelerated bearing wear or abnormal equipment operation. Generally, special assembly auxiliary tooling is required to achieve the assembly.

[0004] For four-point ball contact bearings of different sizes and specifications, it is necessary to replace the corresponding assembly sleeve to adapt to the inner or outer ring size of the bearing. Traditional tooling assembly sleeves are mostly fixed with bolts, and replacement requires the use of tools such as wrenches and screwdrivers, which is cumbersome and inefficient. At the same time, the workpiece is prone to loosening and displacement during assembly, affecting the bearing assembly accuracy. Therefore, an auxiliary tooling for four-point ball contact bearing assembly is proposed to solve the above problems. Utility Model Content

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Reference Figure 1 , Figure 2 and Figure 5This utility model provides an embodiment of an auxiliary tooling for assembling four-point ball contact bearings, including a frame 1. A cylinder 2 is fixedly connected to the middle of the frame 1, and a pressure head 3 is fixedly connected to the output end of the cylinder 2. A quick-connect assembly is installed at the bottom of the pressure head 3, and an assembly sleeve 9 is installed in the middle of the quick-connect assembly. The assembly sleeve 9 directly contacts the bearing, and its size is customized according to the size of the four-point ball contact bearing to be assembled. The cylinder 2 drives the pressure head 3 and the connected assembly sleeve 9 to press down, and the assembly sleeve 9 presses the bearing onto the bearing housing and other workpieces to complete the bearing assembly. The quick-connect assembly allows for quick disassembly, assembly, and replacement of the assembly sleeve 9, so that the corresponding assembly sleeve 9 can be replaced according to the bearing of different sizes to meet the assembly requirements of four-point ball contact bearings of different specifications. A clamping mechanism is installed in the middle of the frame 1. The clamping mechanism can center and clamp the workpiece to prevent it from shifting during assembly. The quick-connect assembly includes a snap-fit ​​connector 4, which is fixedly connected to the bottom of the pressure head 3. A threaded tube 5 is fixedly connected to the bottom of the pressure head 3. Multiple snap-fit ​​blocks 6 are fixedly connected to the bottom end of the threaded tube 5. The snap-fit ​​blocks 6 and the assembly sleeve 9 snap-fit ​​together. A threaded sleeve 8 is threadedly connected to the outside of the threaded tube 5. A snap-fit ​​connector 7 is fixedly connected to the top of the assembly sleeve 9. Snap-fit ​​connector 4 and snap-fit ​​connector 7 snap-fit ​​together. After snap-fit ​​connector 4 and snap-fit ​​connector 7 are aligned, the threaded sleeve 8 is tightened on the outside of the threaded tube 5. During the tightening process, the conical inner wall of the threaded sleeve 8 will squeeze the snap-fit ​​blocks 6, causing the snap-fit ​​blocks 6 to clamp the outside of the assembly sleeve 9. The snap-fit ​​with the assembly sleeve 9 improves the stability of the assembly sleeve 9 installation. Reference Figures 1-4 The clamping mechanism includes a transmission assembly and a clamping assembly. The transmission assembly provides power to the clamping assembly, enabling the clamping assembly to clamp the workpiece. The transmission assembly includes a motor 15, which is fixedly connected to the bottom of the frame 1. A gear 14 is fixedly connected to the output end of the motor 15. The gear 14 is rotatably connected inside the frame 1. A gear 13 is rotatably connected inside the frame 1. The gear 13 and gear 14 mesh with each other. The motor 15 drives the gear 14 to rotate, and the meshing transmission of the gear 14 can drive... When gear 13 rotates, the clamping assembly includes a slider 12, which is slidably connected to the middle of gear 13. A connecting block 11 is fixedly connected to the top of slider 12, and a clamping block 10 is fixedly connected to the top of connecting block 11. The clamping block 10 is slidably connected to the outside of frame 1. When gear 13 rotates, it will drive slider 12 to slide in and out in the middle, thereby driving connecting block 11 and clamping block 10 to slide in and out. The clamping block 10 will center and clamp the workpiece to prevent the workpiece from shifting during assembly, thereby ensuring the stability of the bearing installation process. Reference Figures 1-5The outer side of the locking block 6 is provided with locking grooves 21, and the outer side of the mounting sleeve 9 is provided with locking slots 22. The locking grooves 21 engage with the inside of the locking slots 22. Through the cooperation between the locking block 6 and the locking slots 22, the locking block 6 is engaged with the mounting sleeve 9, thereby improving the stability of the mounting sleeve 9. A guide plate 17 is fixedly connected to the outer side of the cylinder 2. A guide rod 18 is fixedly connected to the top of the guide plate 17. The guide rod 18 is slidably connected to the middle of the frame 1. A limit block 19 is fixedly connected to the top of the guide rod 18. The guide rod 18 and the guide plate 17 provide guidance to ensure that the pressing direction is perpendicular to the side of the workpiece assembly. The main unit 16 is installed on the top of the frame 1. The main unit 16 integrates a PLC control system, which can receive operator commands to control the pressing pressure and pressing stroke of the cylinder 2. This is existing technology and will not be described in detail here. Multiple support seats 20 are installed at the bottom of the frame 1 to support the tooling. Multiple sliding grooves 23 are opened in the middle of the gear 13. The slider 12 is slidably connected inside the sliding groove 23. The gear 13 realizes the sliding inward and outward movement of the slider 12 through the sliding groove 23. Multiple sliding grooves 24 are opened in the middle of the frame 1. The connecting block 11 is slidably connected inside the sliding groove 24. The connecting block 11 cooperates with the sliding groove 24 to realize the sliding of the clamping block 10 and the clamping of the workpiece.

[0013] Working principle: First, snap-fit ​​connector 7 and snap-fit ​​connector 4 are engaged for alignment. After alignment, tighten the threaded sleeve 8 on the outside of the threaded tube 5. When tightening, the conical inner wall of the threaded sleeve 8 will squeeze the locking block 6, causing the locking block 6 to press against the outside of the mounting sleeve 9. The engagement of the locking threads 21 and the locking groove 22 improves the stability of the mounting sleeve 9, ensuring that the mounting sleeve 9 is firmly installed below the pressure head 3. The mounting sleeve 9 can be quickly removed by unscrewing the threaded sleeve 8 from the outside of the threaded tube 5. This allows for the replacement of the corresponding mounting sleeve 9 according to different bearing sizes, improving the tooling's adaptability to bearings of different sizes.

[0014] After installing the mounting sleeve 9, place the workpiece in the corresponding installation position and start the motor 15. The motor 15 drives the gear 2 14 to rotate, which in turn drives the gear 13 to rotate. The gear 13 drives the slider 12 to slide in and out through the slide groove 23, which in turn drives the connecting block 11 and the clamping block 10 to slide in and out. This causes the clamping block 10 to clamp the workpiece in a fixed shape, preventing the workpiece from shifting during assembly. After the workpiece is clamped, start the cylinder 2. The cylinder 2 drives the pressure head 3 and the mounting sleeve 9 below it to press down, pressing the bearing onto the corresponding workpiece through the mounting sleeve 9, thus completing the bearing assembly.

[0015] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
