Description

Technical Field

[0001] The utility model relates to the field of bearings, in particular to a ball loading module and automatic sleeve-fitting equipment for ball bearings. Background Art

[0002] Bearings are important components in mechanical equipment. Their main functions are to support mechanical rotating bodies, bear loads, reduce friction coefficients during movement, and ensure rotation accuracy. Bearings usually include an inner ring, an outer ring, rolling elements, and a cage, where the cage is used to limit the rolling elements.

[0003] The assembly of rolling elements is the core step of bearing assembly processing. For deep groove ball bearings, due to the limited relative space between the inner ring and the outer ring, the inner ring needs to be offset relative to the outer ring during the rolling element installation process, leaving enough space on one side for the rolling elements to be installed. After a specific number of rolling elements are installed, the inner ring is reset relative to the outer ring, and the position of the rolling elements is adjusted to complete the assembly.

[0004] In existing processing practices, the above assembly operations are usually completed manually. The installation of the rolling element is difficult because it is necessary to control the relative position of the inner ring and the outer ring, and to ensure that the position of the rolling element is stable after installation, resulting in low assembly efficiency. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a ball loading module and an automatic assembly device for ball bearings, which have the advantages of reliable assembly and high efficiency.

[0006] In order to solve the above technical problems, the technical solutions provided by the utility model are as follows: a ball loading module, comprising a ferrule positioning seat and an operating unit, the upper surface of the ferrule positioning seat being a ferrule positioning surface; the ferrule positioning seat is provided with a guide channel, a rolling body receiving channel and an outer ring limit block, the outer ring limit block is arranged on the ferrule positioning surface, the guide channel and the rolling body receiving channel are located on one side of the outer ring limit block, and penetrate the ferrule positioning seat up and down; the rolling body receiving channel extends in an arc shape, and both ends are inclined toward the direction of the outer ring limit block; the guide channel is located between the rolling body receiving channel and the outer ring limit block, and extends in a long strip shape in the direction from the rolling body receiving channel to the outer ring limit block;

[0007] The operating unit comprises a rolling body receiving boss and an inner ring adjusting block, wherein the rolling body receiving boss corresponds to the rolling body receiving channel; the inner ring adjusting block corresponds to the guide channel and can slide along the guide channel.

[0009] Then the rolling element receiving boss is inserted from bottom to top into the rolling element receiving channel and enters between the inner ring and the outer ring. The inner ring adjustment block is inserted from bottom to top through the guide channel into the inner ring. At the same time, the inner ring adjustment block moves along the guide channel to drive the inner ring to move toward the outer ring limit block, leaving enough space on the other side for the rolling element to be installed. Finally, the rolling elements are installed one by one and fall on the rolling element receiving boss.

According to the detection results of the ring, the ball counter moves to the matching ball storage container to take the rolling body, and transfers it to the ball guide unit, which guides it through the ball guide channel and transports it to the ball loading module to complete the assembly operation. The quantitative ball removal can be achieved by controlling the volume of the ball counting cavity.

[0019] The automatic assembly equipment of the present application can complete the selective quantitative ball taking operation of rolling bodies with different error levels, and complete the automatic feeding and assembly of rolling bodies, and has the advantage of a high degree of automation.

[0027] Preferably, the error-proofing component also includes a surplus detection unit, which is located on a side of the second in-place detection unit away from the first in-place detection unit and maintains a specific distance from the second in-place detection unit; when the first in-place detection unit and the second in-place detection unit both detect the presence of rolling bodies at the corresponding positions of the ball guide channel, and the surplus detection unit does not detect the presence of rolling bodies at the corresponding positions of the ball guide channel, it is deemed that the number of rolling bodies in place is accurate.

[0028] According to the design requirements, the number of rolling elements is determined.

The ball storage component includes a plurality of ball storage containers 11, and the outlet end of the ball storage container 11 is provided with a ball storage switch unit 15. The ball distribution component includes a ball counter 12 and a ball distribution drive 14. The ball counter 12 is provided with a ball counting cavity 121 with a specific space.
