The invention discloses a motor rotor automatic assembling
machine including an iron core feeding device, a main shaft feeding device, a press-fit device, an insulating sheet feeding device, a turning device, a dispensing device, a
commutator feeding device, a rotary disc conveyer, and a discharging device. The rotary disc conveyer includes a first
rotating disc and a second
rotating disc, the iron core feeding device, the main shaft feeding device, the press-fit device, and the insulating sheet feeding device are cooperated on the first
rotating disc to assemble an iron core, a main shaft, and an insulation sheet into a half-finished rotor, the turning device conveys the half-finished rotor to the second rotating disc, the insulating sheet feeding device, the dispensing device, the
commutator feeding device, and the press-fit device are cooperated on the second rotating disc to assemble the half-finished rotor, a lower insulation sheet, and a
commutator into a finished rotor, and the discharging device takes the finished rotor off the second rotating disc and rotates for discharging. The whole
machine is compact and reasonable in structure, high in efficiency, low in cost, and high in
automation degree.
