Abstract
This application relates to a disposable internal pin loading machine specifically for double-row needle roller bearings in the field of bearing processing technology. It includes a needle roller feeding mechanism, a positioning mechanism, and a disposable internal pin loading mechanism. The needle roller feeding mechanism feeds needle rollers into the positioning mechanism, which positions the cage and needle rollers. The disposable internal pin loading mechanism inserts the needle rollers into the cage in a single operation. This disposable internal pin loading machine, through the coordinated design of the specially designed needle roller feeding mechanism, positioning mechanism, and disposable internal pin loading mechanism, enables one-time pin loading of needle roller bearings, especially double-row needle roller bearings, significantly improving loading efficiency and ensuring product quality.
