Method and special device for rotary crankshaft cleaning and blowing

The invention relates to a crankshaft cleaning machine and a rotary crankshaft cleaning and blowing method. A conveying mechanism conveys work pieces in places, a work piece clamping mechanism clamps and drives the work pieces to rotate, and a cleaning and blowing mechanism sprays, cleans and blows the rotary work pieces. The rotary crankshaft cleaning and blowing method is simple and environmentally friendly, has reasonable technology, saves energy, enables the work pieces to continuously rotate when being cleaned and blown so that each side can directly contact with cleaning liquid or blowing wind, and the cleaning and blowing efficiency and the quality are effectively improved. In addition, the special device for rotary crankshaft cleaning and blowing has simple structure, is fully automatically controlled and operated stably and reliably during the crankshaft cleaning and blowing.
