The invention relates to an unloading mechanism for shaft sleeve assembly. The unloading mechanism comprises a frame and a power distribution control box; a shaft sleeve mounting turntable is arrangedon the frame, and is connected to a shaft sleeve mounting motor; loading holes, in shaft fit, are uniformly formed in the shaft sleeve mounting turntable; and a shaft loading device, a shaft sleeve loading device, a screw rod loading device, a shaft sleeve pressing device and a shaft sleeve unloading device cooperating with the loading holes and connected to the power distribution control box arearranged on the outer side of the shaft sleeve mounting turntable in sequence. The unloading mechanism for shaft sleeve assembly is provided with the shaft sleeve mounting turntable; the turntable isuniformly provided with the loading holes in shaft fit; and the shaft loading device, the shaft sleeve loading device, the screw rod loading device, the shaft sleeve pressing device and the shaft sleeve unloading device are arranged on the outer side of the turntable in sequence to realize integral, automatic and continuous operation of shaft sleeves and screw rods, so that the mounting efficiency of the shaft sleeves is greatly improved, and meanwhile, the equipment utilization rate is improved.
