Outer spherical surface trimming device for retainer in ball cage

Abstract

The invention belongs to the technical field of automobile transmission and provides an outer spherical surface trimming device for a retainer in a ball cage. The device comprises a plate, a loading device, a feeding mechanism, a trimming mechanism, an unloading mechanism, a blanking device and a power driving mechanism, wherein the loading device is fixed to the top of the plate; the blanking device is arranged on a side portion of the plate; the power drive mechanism drives the feeding mechanism, the unloading mechanism and the trimming mechanism to work, respectively; the plate is provided with a loading cambered surface and an unloading cambered surface, respectively; the feeding mechanism conveys a retainer to be trimmed onto the trimming mechanism in a swinging manner along the loading cambered surface; and after the retainer is trimmed by the trimming mechanism, the unloading mechanism conveys the trimmed retainer to the blanking device for blanking in the swinging manner along the unloading cambered surface. The whole device is high in operation automation degree, and safe, stable and reliable in feeding and blanking; therefore, the labor intensity of workers is greatly reduced; the unstable factor of human operation faults can be reduced to the lowest degree; and the outer spherical surface processing accuracy of the retainer is ensured.

Description

technical field [0001] The invention belongs to the technical field of automobile transmission and relates to a ball cage, in particular to an outer spherical surface trimming device of a cage in the ball cage. Background technique [0002] The universal joint assembly for automobiles is generally composed of inner ball cage, outer ball cage, intermediate shaft and other parts. It is a mechanical part installed between the automobile differential or the end reduction gear and the wheel to transmit motion and torque. , and at the same time change the working angle and perform telescopic sliding. The above functions are mainly realized through the inner ball cage and the outer ball cage. [0003] For example, a constant velocity universal joint structure disclosed in Chinese Patent Document [Notice No.: CN101672331] includes a spherical shell, a cage, a star sleeve and a spherical seat, the inner spherical surface of the spherical shell and the outer spherical surface of the c...

Problems solved by technology

[0004] At present, when processing the cage, it is necessary to trim the outer spherical surface and the inner spherical surface of the cage and other components, so that the cage can be closely matched with other parts such as spherical shells, star sleeves, and steel balls. The trimming of the outer spherical surface and the inner spherical surface of the cage is mainly carried out manually and visually. Obviously, the disadvantage of this method is that it is not only time-consuming and labor-intensive, but also low in efficiency, and it is difficult to ensure the machining accuracy of the cage. This will cause spherical shells The wear between the inner spherical surface and the outer spherical surface of the cage and the inner spherical surface of the cage and the outer spherical surface of the star sleeve is large and uneven, the operation is unstable, abnormal noise or blockage occurs, and the cage is easy to break during use, reducing the The service life of the cage
