[0018] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0019] This utility model provides, for example Figure 1-4 The precision bearing positioning and assembly device shown includes: Workbench 1; A horizontal mounting slot 2 is provided at the center of the surface of the workbench 1. The workbench 1 is provided with two vertical mounting slots 3, which are located on the upper and lower sides of the horizontal mounting slot 2, respectively. The positioning component is used to position the bearing and is located on the worktable 1.

[0020] The inner and outer rings of the bearing are placed on workbench 1 for assembly. First, the outer ring of the bearing is clamped and positioned by the positioning component to prevent displacement. After the outer ring is clamped and fixed, the operator puts the inner ring of the bearing inside the outer ring and inserts the balls between the outer and inner rings. After the balls are inserted, the inner ring of the bearing is clamped and positioned again by the positioning component. This improves the stability of the bearing assembly, prevents displacement of the inner and outer rings, facilitates the assembly of the bearing, and improves the assembly efficiency.

[0021] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 3 The positioning component includes an outer ring clamping block 4, of which there are two. A guide slide rod 5 is fixedly connected in the vertical mounting groove 3. The outer ring clamping block 4 is located in the vertical mounting groove 3 and is slidably connected to the guide slide rod 5. A tension spring 6 is fitted on the guide slide rod 5. A bidirectional threaded screw 7 is rotatably connected in the horizontal mounting groove 2. Two outer ring positioning blocks 8 are connected in the horizontal mounting groove 2. The outer ring positioning blocks 8 are threadedly engaged with the bidirectional threaded screw 7.

[0022] When assembling the bearing, the outer ring of the bearing is used to push the outer ring clamping block 4. The outer ring clamping block 4 slides along the guide slide rod 5 in the vertical mounting groove 3. The movement of the outer ring clamping block 4 stretches the tension spring 6, placing the outer ring of the bearing between the two outer ring clamping blocks 4. Under the tension of the tension spring 6, the two outer ring clamping blocks 4 clamp the outer ring of the bearing. The bidirectional threaded screw 7 rotates to drive the two outer ring positioning blocks 8 to move relative to each other. The two outer ring positioning blocks 8 move closer to each other to clamp and fix the outer ring of the bearing. The outer ring positioning blocks 8 and the outer ring clamping blocks 4 clamp and fix the outer ring of the bearing at the center of the worktable 1, preventing the outer ring of the bearing from shifting and improving the stability during bearing assembly.

[0023] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 One end of the tension spring 6 is fixedly connected to the side wall of the vertical mounting groove 3, and the other end of the tension spring 6 is fixedly connected to the outer ring clamping block 4. Multiple universal balls 9 are installed on the outer ring clamping block 4.

[0024] After the outer ring clamping block 4 clamps the outer ring of the bearing, the universal ball 9 fits against the outer wall of the bearing outer ring. When the two outer ring positioning blocks 8 contact the bearing outer ring, they can push the bearing outer ring to move, reducing the friction on the bearing outer ring, avoiding scratches on the bearing outer ring, and improving the quality of the finished bearing.

[0025] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 4 The positioning component also includes an inner ring positioning block 10, which has two inner ring positioning blocks 10. A fixed bracket 11 is fixedly connected to the center of the transverse mounting groove 2. The fixed bracket 11 is located above the bidirectional threaded screw 7. Electric push rods 12 are installed on both sides of the fixed bracket 11. The telescopic end of the electric push rod 12 is fixedly connected to the inner ring positioning block 10. The two electric push rods 12 operate synchronously.

[0026] After the balls are filled, the two electric push rods 12 start working simultaneously. The telescopic ends of the electric push rods 12 extend and drive the inner ring positioning blocks 10 to move. The two inner ring positioning blocks 10 fit against the inner wall of the bearing inner ring, making the inner ring and outer ring of the bearing concentric. The inner ring of the bearing is positioned by the inner ring positioning blocks 10, which improves the stability of the bearing during assembly, avoids displacement of the inner and outer rings of the bearing, facilitates the assembly of the bearing, and improves the assembly efficiency.

[0027] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 Multiple anti-slip strips 13 are fixedly connected to the surfaces of the inner ring positioning block 10 and the outer ring positioning block 8, and the anti-slip strips 13 are arranged vertically.

[0028] The anti-slip strip 13 contacts the inner and outer rings of the bearing, which improves the anti-slip effect, prevents the inner and outer rings of the bearing from shifting, and improves stability.

[0029] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 3 A drive motor 14 is installed on the side wall of the workbench 1. The output end of the drive motor 14 is fixedly connected to one end of the bidirectional threaded screw 7. The bidirectional threaded screw 7 has two threaded grooves with opposite spiral directions. Two outer ring positioning blocks 8 are threadedly connected to the two threaded grooves respectively. The two outer ring positioning blocks 8 move in opposite directions.

[0030] When the drive motor 14 starts working, the output end of the drive motor 14 drives the bidirectional threaded screw 7 to rotate. The two threaded grooves on the bidirectional threaded screw 7 drive the two outer ring positioning blocks 8 to move respectively, and the two outer ring positioning blocks 8 move closer or further away from each other.
