Abstract

The application discloses a shaft sleeve riveting and pressing device for motor end cover machining and relates to the technical field of motor machining. The device comprises a base, a bearing disc rotatably arranged on the base, a plurality of work station grooves in the form of annular distribution are formed in the bearing disc, and a driving element for driving the bearing disc to intermittently rotate is arranged on the base. A plurality of positioning elements are respectively arranged in the plurality of work station grooves. The positioning element is composed of a plurality of first supporting rods, a plurality of second supporting rods and a plurality of third supporting rods. The first supporting rods can slide horizontally, the positioning element can be retracted or expanded, the positioning element can be retracted before assembly to facilitate smoother assembly, and the positioning element is expanded after assembly to position the assembled motor end cover and shaft sleeve. The cooperation of retraction and expansion is not only suitable for riveting and pressing of accessories of different sizes, but also improves the general flexibility.
