Crankshaft cleaning device

The crankshaft cleaning device comprises a driving motor bin, a cleaning bin is welded to the top of the driving motor bin, and an upper cover is arranged at an opening in the top of the cleaning bin. After a cleaning agent and water are injected into the cleaning bin, the upper cover vertically covers the opening in the top of the cleaning bin, the transmission shaft and the brush vertically enter the inner cavity of the cleaning bin, the rotating speed of the driving motor is set to be smaller than that of the servo motor, and the rotating directions of the driving motor and the servo motor are opposite; the output end of the servo motor drives the transmission shaft to rotate the brush so as to clean the outer ring of the crankshaft body, due to the fact that the brush is soft, the tip end of the brush can be attached to the outer surface of the crankshaft body to the maximum extent, the effect of cleaning the concave-convex position of the crankshaft body is achieved, and meanwhile the brush is driven by
