The rotating disk 71 is rotatably connected to the surface of the machine base 2 facing the installation station. The rotating axis of the rotating disk 71 and the height direction of the machine base 2 are parallel to each other. Multiple limiting disks 72 are connected to the surface of the rotating disk 71 at intervals around the axis of the rotating disk 71. The surface of the limiting disk 72 is provided with a limiting groove 721 for the ring body 1 to be embedded. The inner wall of the limiting groove 721 abuts the inner ring wall of the ring body 1 to form a positioning. The rotating disk 71 rotates on the surface of the machine base 2 and drives the multiple limiting disks 72 to pass through the installation station in turn, thereby realizing the sequential assembly of multiple steel balls on multiple ring bodies 1 and improving the feeding efficiency of the ring body 1.

[0048] The implementation principle of the annular steel ball feeding mechanism of the present application is as follows: when multiple steel balls on the ring body 1 are fed, the feeding motor 33 drives the scraper 34 to rotate in the inner cavity of the storage tray 31, and the scraper 34 drives the steel balls in the storage tray 31 to embed into the storage holes 321.
