Patent ID: 10598481

Abstract:
Around a crankshaft (S) supported by a support device (10), a first shape measuring device (31) to a fourth shape measuring device (34) are disposed, and the crankshaft (S) and the first shape measuring device (31) to the fourth shape measuring device (34) are relatively movable in an axial direction (X direction) of the crankshaft (S). The first shape measuring device (31) and the third shape measuring device (33) are disposed so as to face to one X direction and acquire partial shape information (including the other side surfaces in the X direction of counterweights (S2)) of the crankshaft S, and further, the second shape measuring device (32) and the fourth shape measuring device (34) are disposed so as to face to the other X direction and acquire partial shape information (including one side surfaces in the X direction of the counterweights (S2)) of the crankshaft S. This makes it possible to accurately inspect a shape of the crankshaft (S) in a short time.
