This invention belongs to the field of crankshaft machining technology, specifically a self-rotating clamping device for machining motor crankshafts. Addressing the problem in existing technologies where there is no equipment that can arbitrarily place the crankshaft for alignment and clamping to detect rotational deviations, the following solution is proposed: A base housing is included, with a moving mechanism located between the bottom sides of the base housing. A groove is formed on the top of the base housing, and a clamping main housing is bolted into the groove. An inner base is welded to the inner wall of the clamping main housing.
