A differential gear shaft assembly equipment

Abstract

The invention relates to an assembly device for a rotating shaft of a differential, comprising an assembly seat and a movable seat, the assembly seat is provided with a guide hole, the guide hole is facing the installation hole of the rotating shaft on the differential, and the frame is provided with a guide rail of the movable seat , the movable seat is movably installed on the guide rail of the movable seat, a limit pin is provided on the movable seat, and a lifting drive device is arranged between the limit pin and the movable seat, the limit pin can be inserted into the pin hole on the rotating shaft, and the rotating shaft assembly equipment It also includes a rotating shaft pushing mechanism, the rotating shaft pushing mechanism includes a cylinder, the piston rod of the cylinder is aligned with the rear end face of the rotating shaft, and a limit pin lifting control device is also included, and the limit pin lifting control device controls the lifting of the limit pin; When the depth of the rotating shaft inserted into the mounting hole of the rotating shaft reaches the set value, the limit pin is lowered, and the limit pin is no longer inserted into the pin hole, and the rotating shaft pushing mechanism continues to push the rotating shaft until the rotating shaft is completely inserted into the mounting hole of the rotating shaft. Effectively guarantee the insertion accuracy of the rotating shaft and have high reliability.

Description

technical field [0001] The invention relates to an assembly device for a rotating shaft of a differential gear. Background technique [0002] After installing the planetary bevel gear and the half shaft vertical wheel in the differential case, it is necessary to install the planetary bevel gear shaft between the two planetary bevel gears and the stop pin between the planetary bevel gear shaft and the differential case, now In the existing technology, manual assembly is often used. First, the planetary bevel gear shaft is pressed into the two planetary bevel gears, and then the stop pin assembly is completed. The assembly process requires a lot of manpower, and the degree of automation is low, which affects the need for mass production. Moreover, manual assembly also has defects of unstable quality, which can easily affect product quality. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a differential gear rotati...
