Pressing-assembling device for force-transmitting steel balls of universal joint

Abstract

The invention provides a pressing-assembling device for force-transmitting steel balls of a universal joint. According to the pressing-assembling device, a steel ball feeding mechanism supplies steel balls one by one to steel ball pressing-assembling mechanisms, a workpiece positioning machine mechanism is used for positioning a workpiece and enabling the workpiece to stay in a correct position, and the steel ball pressing-assembling mechanisms press the steel balls into the workpiece. Compared with the prior art, assembling of the steel balls is automatically completed by the pressing-assembling device, so that the labor intensity of operators is reduced, the steel balls are pressed and assembled by the corresponding steel ball pressing-assembling mechanisms in the assembling process, the assembling precision of the steel balls can be effectively guaranteed, and the usability of the universal joint is optimized; compared with traditional manual assembling steel ball process, the steel balls are mechanically assembled, the efficiency is improved, and the assembling speed of the pressing-assembling device is five seconds per steel ball while original manual assembling speed is about eight seconds per steel ball; and the phenomena of neglected-assembling of the steel balls can exist when the steel balls are assembled manually, by adopting the pressing-assembling device to assemble the steel balls, the steel ball pressing-assembling mechanisms can work at the same time so that the phenomenon of the neglected-assembling can be effectively avoided.

Description

technical field [0001] The invention relates to a steel ball pressing device, in particular to a universal joint force transmission steel ball pressing device, which belongs to the field of universal joint assembly. Background technique [0002] The universal joint is mainly composed of a cylindrical shell, a force-transmitting steel ball, an inner star wheel and a cage cage. When assembling, first assemble the inner star wheel and the cage, and the window of the cage cage needs to be aligned with the raceway of the inner star wheel. Then put the power transmission steel ball into the corresponding inner star wheel raceway in the window of the cage. Finally, assemble the assembled inner star wheel with the cylindrical shell. [0003] At present, manual assembly is mostly used in the production of universal joints. In the whole process, the assembly of the inner star wheel is the most important thing to pay attention to, because the installation accuracy of the force transm...
