The invention relates to an automatic shaft sleeve assembly machine which comprises a rack and a power distribution control cabinet. The rack is provided with a shaft sleeve mounting rotary disc which is connected to a shaft sleeve mounting motor and uniformly provided with loading holes matched with shafts. A shaft feeding device, a shaft sleeve feeding device, a screw feeding device, a shaft sleeve pressing device and a shaft sleeve discharging device which are matched with the loading holes and connected to the power distribution control cabinet are sequentially arranged outside the shaft sleeve mounting rotary disc. According to the automatic shaft sleeve assembly machine, the shaft sleeve mounting rotary disc is arranged and uniformly provided with the loading holes matched with the shafts, the shaft feeding device, the shaft sleeve feeding device, the screw feeding device, the shaft sleeve pressing device and the shaft sleeve discharging device are sequentially arranged outside the shaft sleeve mounting rotary disc, integrated automatic continuous operation of shaft sleeves and screws is achieved, the shaft sleeve mounting efficiency is greatly improved, and meanwhile, the equipment utilization rate is increased.
