The invention discloses manufacturing equipment of a motor rotor, and relates to the technical field of motor rotor manufacturing equipment. The manufacturing equipment comprises an operating table, wherein a U-shaped plate, a sliding rail, a pair of L-shaped baffles and a fixing plate are sequentially arranged at the top part of the operating table, and an air cylinder group is arranged at the top part of the U-shaped plate and comprises an air cylinder and a push rod, a connecting rod, a push plate, a push block, a plurality of bearings, a push spring and a push plate are arranged at the toppart of the U-shaped plate, one end of the connecting rod is installed on the push rod, and a guide rod is installed on the side wall of one side of the push plate. The manufacturing equipment is reasonable in structure, by arranging the connecting rod, the push plate, the push block, a thrust spring, the push spring and the push plate, after each bearing is press-fitted, the bearing placed on aplacement groove is automatically filled and fed, thus semi-automation is achieved, and time and labor are saved; and by arranging a placement block and a compression spring, the bearings do not needto be manually aligned with a rotor assembly shaft, and the press-fitting speed of the bearings is increased.
