Soaking type cleaning device for lathe spindle maintenance

The utility model discloses a soaking type cleaning device for lathe spindle maintenance, which relates to the technical field of lathe spindle cleaning devices and comprises an ultrasonic cleaning box, a lifting frame is connected to the top of the ultrasonic cleaning box in a lifting manner, a double-shaft motor is fixed in the lifting frame, and second chain wheels are fixed on output shafts on two sides of the double-shaft motor. Limiting retainers are fixed to the two sides of the bottom of the lifting frame. The two sets of rotating rings drive the main shaft to descend into the ultrasonic cleaning box, meanwhile, the double-shaft motor drives the two sets of second chain wheels to rotate, the second chain wheels drive the first chain wheels to rotate through the chains, the two sets of rotating rings rotate in the cleaning liquid, and under the action of the self gravity of the main shaft, the main shaft is driven to rotate. The main shaft rotates relative to the two sets of rotating rings in the clean
