Abstract
Description
Technical Field
[0001] The present invention relates to the pairing of bearing rings, and more specifically to a device for sorting, pairing, and sequencing bearing rings. Background Art
[0002] As a key component in the mechanical transmission system, the accuracy and performance of bearings directly affect the operating efficiency and service life of equipment. A bearing usually consists of an inner ring, an outer ring, rolling elements such as balls or rollers, and a cage. Among them, the size matching and geometric accuracy of the inner and outer rings are crucial for the assembly quality of the bearing. During the bearing manufacturing process, the inner and outer rings are usually processed separately. However, due to factors such as machining errors and heat treatment deformation, even for inner and outer rings produced in the same batch, there may be slight differences in their actual sizes and shapes. If randomly paired and assembled, it may lead to uneven bearing clearances, decreased rotational accuracy, and even shortened bearing service life;
[0003] Traditional methods for pairing inner and outer rings mainly rely on manual measurement and manual selection, which are inefficient and easily affected by human factors, making it difficult to meet the large-scale production requirements of high-precision bearings. In recent years, some automated pairing technologies have been proposed, such as the grouping and matching method based on a size sorting machine. However, these technologies usually only perform simple sorting for a single parameter such as inner diameter or outer diameter, and fail to comprehensively consider the geometric tolerances of the inner and outer rings such as roundness, parallelism, and roughness, resulting in the problem that the bearings after pairing may still have insufficient accuracy. In addition, the existing technologies lack efficient automatic sorting and matching algorithms, making it difficult to achieve rapid and accurate pairing of inner and outer rings, which affects production efficiency and bearing quality.

[0033] When using, Figure 1 As shown, the inner ring of the outer bearing ring 6 on the outer ring blanking mechanism 2 is detected by the outer ring detection mechanism 4, and the outer ring of the inner bearing ring 7 on the inner ring blanking mechanism 3 is detected by the inner ring detection mechanism 5. The inner bearing ring 7 or the outer bearing ring 6 is searched based on the detection of the outer bearing ring 6 or the detection of the inner bearing ring 7, that is, when the outer bearing ring 6 is used as a reference, the inner bearing ring 7 is searched, and when the inner bearing ring 7 is used as a reference, the outer bearing ring 6 is searched. Through the movement of the outer ring blanking mechanism 2 and the inner ring blanking mechanism 3, the corresponding matching model is searched. After the model matching is completed, the outer bearing ring 6 and the inner bearing ring 7 are dropped on the sorting mechanism 1 at the same position for sorting, which is convenient for subsequent installation;
[0034] The structure and function of the sorting mechanism 1 are described in detail below;
[0035] The sorting mechanism 1 comprises a sorting bracket 11, and the front and rear ends of the sorting bracket 11 are rotatably connected to rotating rollers 12, and a sorting belt 13 is transmission-connected between the two rotating rollers 12, and a plurality of sorting holes 14 are arranged on the sorting belt 13. A power mechanism I for driving the rotating rollers 12 to rotate is fixedly connected to the sorting bracket 11;
[0036] When in use, when the positions of the multiple sorting holes 14 need to be changed, the power mechanism I is started, and the power mechanism I is preferably a servo motor. The output shaft of the power mechanism I drives the rotating roller 12 to rotate, and the rotating roller 12 drives the sorting belt 13 to move, and the sorting belt 13 drives the multiple sorting holes 14 to move, thereby adjusting the positions of the multiple sorting holes 14, so that the outer bearing ring 6 and the inner bearing ring 7 can fall into the same sorting hole 14, which is convenient for subsequent assembly;
[0037] The structure and function of the outer ring blanking mechanism 2 are described in detail below;
[0038] The outer ring blanking mechanism 2 includes a support I 21, the support I 21 is fixedly connected to the sorting support 11, a blanking cylinder I 22 is fixedly connected to the support I 21, a support ring I 23 is fixedly connected to the bottom of the blanking cylinder I 22, a rotating ring I 24 is rotatably connected to the support ring I 23, a plurality of receiving holes I 25 are provided on the rotating ring I 24, the blanking cylinder I 22 communicates with the receiving holes I 25, a covering support I 26 is fixedly connected to the support ring I 23, the covering support I 26 is located outside the rotating ring I 24, and a power mechanism II for driving the rotation of the rotating ring I 24 is fixedly connected to the support ring I 23;

[0040] During use, the outer bearing rings 6 to be placed and measured are placed side by side in the blanking cylinder I 22. The lower end of the blanking cylinder I 22 communicates with the receiving holes I 25, so that one of the outer bearing rings 6 will fall into the receiving holes I 25. The power mechanism II is started, and the output shaft of the power mechanism II starts to rotate. The output shaft of the power mechanism II drives the rotating ring I 24 to rotate, and the rotating ring I 24 drives a plurality of receiving holes I 25 to move, thereby driving the outer bearing rings 6 in the plurality of receiving holes I 25 to move, so that the outer bearing rings 6 move onto the expansion cavity I 27;
[0041] The gas pipeline I 28 is pre-connected to an air pump, and gas is introduced into the expansion cavity I 27 through the air pump, so that the expansion cavity I 27 expands inward, thereby supporting the outer bearing ring 6;
[0042] Next, the structure and function of the inner ring blanking mechanism 3 will be described in detail;
[0043] The inner ring blanking mechanism 3 includes a support II 31, the support II 31 is fixedly connected to the sorting support 11, a blanking cylinder II 32 is fixedly connected to the support II 31, a support ring II 33 is fixedly connected to the bottom of the blanking cylinder II 32, a rotating ring II 34 is rotatably connected to the support ring II 33, a plurality of receiving holes II 35 are provided on the rotating ring II 34, an insertion groove 36 is provided on each receiving hole II 35, a covering support II 37 is fixedly connected to the support ring II 33, the covering support II 37 covers the outside of the rotating ring II 34, and a power mechanism III for driving the rotation of the rotating ring II 34 is fixedly connected to the support ring II 33;
[0044] The support ring II 33 is fixedly connected with an expansion cavity II 38, a gas pipeline II 39 is provided on the expansion cavity II 38, and the expansion cavity II 38 is located above the sorting hole 14;
[0045] During use, the inner bearing rings 7 to be placed and measured are placed side by side in the blanking cylinder II 32. The lower end of the blanking cylinder II 32 communicates with the receiving hole II 35. In this way, one of the inner bearing rings 7 will fall into the receiving hole II 35. Start the power mechanism III. The output shaft of the power mechanism III starts to rotate. The output shaft of the power mechanism III drives the rotating ring II 34 to rotate. The rotating ring II 34 drives a plurality of receiving holes II 35 to move, and further drives the inner bearing rings 7 in the plurality of receiving holes II 35 to move, so that the inner bearing rings 7 move onto the expansion cavity II 38;
[0046] Pre-connect the gas pipeline II 39 to the air pump in advance. Pass the gas into the expansion cavity II 38 through the air pump, so that the expansion cavity II 38 expands inward, and then support the inner bearing ring 7;
[0047] Next, the structures and functions of the outer ring detection mechanism 4 and the inner ring detection mechanism 5 will be described in detail;
[0048] The outer ring detection mechanism 4 includes a telescopic mechanism I 41. The telescopic mechanism I 41 is fixedly connected to the support ring I 23. A telescopic mechanism II 42 is fixedly connected to the telescopic end of the telescopic mechanism I 41. A pressure sensor I 43 is fixedly connected to the telescopic end of the telescopic mechanism II 42;
[0049] The pressure sensor I 43 can contact the inner ring of the outer bearing ring 6 that moves to the upper side and is located in the receiving hole I 25;
[0050] The inner ring detection mechanism 5 includes a telescopic mechanism III 51. The telescopic mechanism III 51 is fixedly connected to the support ring II 33. A telescopic mechanism IV 52 is fixedly connected to the telescopic end of the telescopic mechanism III 51. A pressure sensor II 53 is fixedly connected to the telescopic end of the telescopic mechanism IV 52;
[0051] The pressure sensor II 53 can contact the outer ring of the inner bearing ring 7 that moves to the upper side and is located in the receiving hole II 35;
[0052] During use, the outer bearing ring 6 is taken as an example for illustration here;
[0053] Start the telescopic mechanism I 41 and the telescopic mechanism II 42. The telescopic mechanism I 41 and the telescopic mechanism II 42 can be hydraulic cylinders or electric push rods. The telescopic end of the telescopic mechanism I 41 drives the telescopic mechanism II 42 to move. The telescopic mechanism II 42 drives the pressure sensor I 43 to move, and then adjusts the height of the pressure sensor I 43, and adjusts the position where the pressure sensor I 43 contacts the outer bearing ring 6. When multiple outer bearing rings 6 of the same model are paired, only the height of the pressure sensor I 43 needs to be adjusted once;
[0054] Start the telescopic mechanism II 42. The telescopic end of the telescopic mechanism II 42 extends a fixed length each time. The telescopic end of the telescopic mechanism II 42 drives the pressure sensor I 43 to move, so that the pressure sensor I 43 contacts the inner ring of the outer bearing race 6. Since the length extended by the telescopic end of the telescopic mechanism II 42 is fixed each time, and due to the different tolerances of the inner ring of the outer bearing race 6, the pressure value of the pressure sensor I 43 is different each time. When the pressure value displayed by the pressure sensor I 43 is large, it indicates that the inner ring of the outer bearing race 6 is small. Therefore, when pairing, a smaller outer ring of the inner bearing race 7 needs to be paired;
[0055] Start the telescopic mechanism III 51 and the telescopic mechanism IV 52. The telescopic mechanism III 51 and the telescopic mechanism IV 52 can be hydraulic cylinders or electric push rods. The telescopic end of the telescopic mechanism III 51 drives the telescopic mechanism IV 52 to move. The telescopic mechanism IV 52 drives the pressure sensor II 53 to move, thereby adjusting the height of the pressure sensor II 53 and adjusting the contact position between the pressure sensor II 53 and the inner bearing race 7. When multiple inner bearing races 7 of the same model are paired, only the height of the pressure sensor II 53 needs to be adjusted once;
[0056] Start the telescopic mechanism IV 52. The telescopic end of the telescopic mechanism IV 52 extends a fixed length each time. The telescopic end of the telescopic mechanism IV 52 drives the pressure sensor II 53 to move, so that the pressure sensor II 53 contacts the outer ring of the inner bearing race 7. Since the length extended by the telescopic end of the telescopic mechanism IV 52 is fixed each time, and due to the different tolerances of the outer ring of the inner bearing race 7, the pressure value of the pressure sensor II 53 is different each time. When the pressure value displayed by the pressure sensor II 53 is large, it indicates that the inner ring of the outer bearing race 6 is large. Therefore, when pairing, the greater the pressure value of the pressure sensor I 43, the smaller the inner ring of the outer bearing race 6 is proved. The smaller the pressure value displayed by the sensor II 53, the smaller the outer ring of the inner bearing race 7 is proved. In this way, the smaller inner ring of the outer bearing race 6 is paired with the smaller outer ring of the inner bearing race 7, and the larger inner ring of the outer bearing race 6 is paired with the larger outer ring of the inner bearing race 7;
[0057] When one of the outer bearing races 6 is used as a reference and the other inner bearing race 7 does not conform to the pairing rule, start the power mechanism III. The output shaft of the power mechanism III starts to rotate. The output shaft of the power mechanism III drives the rotating ring II 34 to rotate. The rotating ring II 34 drives a plurality of receiving holes II 35 to move, thereby driving the inner bearing races 7 in the plurality of receiving holes II 35 to move, so that the inner bearing races 7 move onto the expansion cavity II 38, and then measure the inner bearing races 7 in turn. After finding a suitable inner bearing race 7;
[0058] The expansion cavity Ⅰ 27 contracts, and the outer bearing ring 6 lands on the sorting hole 14. The sorting belt 13 drives the sorting hole 14 to move to the lower side of the expansion cavity Ⅱ 38. The expansion cavity Ⅱ 38 contracts, and the inner bearing ring 7 lands in the same sorting hole 14, thereby completing the matching and sorting of the outer bearing ring 6 and the inner bearing ring 7.
