[0002] In the field of bearing manufacturing, the forming process of bearing rings including inner rings and outer rings is one of the key technologies. Traditional bearing ring forming processes usually adopt methods such as turning, grinding, or cold ring rolling. Although these methods are mature, there are certain limitations when processing rings with complex geometries. For example, some special bearings such as bearings with rotating rollers require the processing of rotating roller receiving grooves such as arc grooves or raceway grooves on the ring to accommodate rolling elements and achieve smooth operation. This groove structure has extremely high requirements for precision and surface quality. Traditional processing methods are often inefficient, costly, and difficult to meet the forming requirements of complex grooves. Summary of the Invention

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.

[0028] As shown in Figure 9 and Figure 10 , it is a structural diagram of the asymmetric bearing ring; in order to machine the storage groove 6, as shown in Figures 1 to 8 , the structure and function of an asymmetric bearing ring forming device will be described in detail below;

[0029] An asymmetric bearing ring forming device includes a mounting seat 11, and two sliding tracks I 12 and two sliding tracks II 15 are fixedly connected to the mounting seat 11. A clamping mechanism 3 is slidably connected to each of the two sliding tracks I 12, and a cutting mechanism 2 is slidably connected to each of the two sliding tracks II 15;

[0030] During use, as shown in Figure 1 , the bearing inner ring 4 or the bearing outer ring 5 to be processed is placed between the two clamping mechanisms 3. The inner ring of the bearing inner ring 4 is clamped by the two clamping mechanisms 3, and the outer ring of the bearing outer ring 5 is clamped by the two clamping mechanisms 3. The two cutting mechanisms 2 can cut and process the outer ring of the bearing inner ring 4 to form two storage grooves 6, and the two cutting mechanisms 2 can cut and process the inner ring of the bearing outer ring 5 to form two storage grooves 6;

[0031] As shown in Figure 10 , the storage grooves 6 on the bearing inner ring 4 and the bearing outer ring 5 are combined to form a storage groove for the rolling elements, which is used to store the rolling elements;

[0032] As shown Figure 2 in the figure, a lead screw I 13 is rotatably connected to the sliding track I 12, and a driving motor I 14 for driving the lead screw I 13 to rotate is fixedly connected to the sliding track I 12;

[0033] Start the driving motor I 14. The driving motor I 14 is preferably a servo motor. The output shaft of the driving motor I 14 drives the lead screw I 13 to rotate.

[0035] The clamping mechanism 3 includes a sliding seat II 31. The sliding seat II 31 is slidably connected to the sliding track I 12 and is threadedly connected to the lead screw I 13. An expansion mechanism IV 32 is fixedly connected to the sliding seat II 31. An expansion mechanism V 33 is fixedly connected to the expansion end of the expansion mechanism IV 32. A motor seat 34 is fixedly connected to the expansion end of the expansion mechanism V 33. Two swing motors II 35 are fixedly connected to the motor seat 34. A swing arm II 36 is fixedly connected to the output shaft of the swing motor II 35. A clamping cylinder 37 is rotatably connected to the swing arm II 36;

[0036] A limiting ring I 38 is fixedly connected to the clamping cylinder 37. An expansion mechanism VI 39 is fixedly connected to the clamping cylinder 37.

The power mechanism I is preferably a servo motor;

[0037] During use, start the expansion mechanism IV 32. The expansion mechanism IV 32 can be a hydraulic cylinder or an electric push rod. The expansion end of the expansion mechanism IV 32 drives the expansion mechanism V 33 to move, thereby adjusting the height of the expansion mechanism V 33. The expansion mechanism V 33 drives the motor seat 34 to move. The motor seat 34 drives the two swing motors II 35 to move. The swing motor II 35 drives the swing arm II 36 to move. The swing arm II 36 drives the clamping cylinder 37 to move, thereby adjusting the height of the clamping cylinder 37;

[0041] By starting the telescopic mechanism IV 32, the telescopic mechanism V 33 and the swing motor II 35, the bearing inner ring 4 and the bearing outer ring 5 with different diameters can be clamped;

[0042] Furthermore, in order to limit the lateral movement of the bearing inner ring 4 and the bearing outer ring 5 and ensure the stability of the bearing inner ring 4 and the bearing outer ring 5 during cutting, when clamping, one side of the bearing inner ring 4 or the bearing outer ring 5 is in contact with the limit ring I 38, and the telescopic mechanism VI 39 is started. The telescopic mechanism VI 39 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism VI 39 drives the limit ring II 310 to move, so that the limit ring II 310 slides on the clamping cylinder 37, and then the limit ring II 310 contacts the bearing inner ring 4 or the bearing outer ring 5, thereby limiting the bearing inner ring 4 or the bearing outer ring 5 and completing the fixation of the bearing inner ring 4 or the bearing outer ring 5;

The plurality of cutting tools II 212 are all slidably connected to the cutting disc I 28, and the plurality of cutting tools I 29 are all slidably connected to the cutting disc II 211;

[0050] During use, as Figure 1 shown, two receiving grooves 6 need to be machined on the outer side of the inner ring 4 of the bearing, and two receiving grooves 6 need to be machined on the inner side of the outer ring 5 of the bearing;

[0051] The processing processes of the inner ring 4 and the outer ring 5 of the bearing will be described in detail below;

[0052] The inner side of the inner ring 4 of the bearing is clamped by four clamping cylinders 37. The drive motor II 17 is started. The output shaft of the drive motor II 17 drives the lead screw II 16 to rotate, so that the cutting mechanism 2 moves horizontally, adjusting the horizontal position of the cutting mechanism 2. The telescopic mechanism I 22 is started. The telescopic mechanism I 22 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I 22 drives the swing motor I 23 to move, thereby adjusting the height of the swing motor I 23. The swing motor I 23 drives the swing arm I 24 to move. The swing arm I 24 drives the telescopic mechanism II 25 to move. The telescopic mechanism II 25 drives the cutting motor 26 to move. The cutting motor 26 drives the rotating cylinder 27 to move. The rotating cylinder 27 drives the cutting disc I 28 to move. The cutting disc I 28 drives the cutting tools I 29 to move, thereby adjusting the height of the cutting tools I 29;

[0055] Furthermore, start the cutting motor 26. The cutting motor 26 is preferably a servo motor. The output shaft of the cutting motor 26 drives the cutting tool I 29 to rotate, so that multiple cutting tools I 29 cut the outer ring of the bearing inner ring 4.

[0056] As Figure 10 shown, by starting the telescopic mechanism I 22, the swing motor I 23 and the telescopic mechanism II 25, the position of the cutting tool I 29 is adjusted, so that the cutting tools I 29 on the two cutting mechanisms 2 are respectively in different positions to cut the bearing inner ring 4.
