Abstract

PURPOSE:To measure automatically a shaft diameter and roundness of a cylindrical member having a recessed groove on the surface by rotating the clyindrical member inserted and held by a measuring piece, and detecting the shaft diameter of a range except a radius vector of the recessed groove part. CONSTITUTION:When a bearing fitting part of a work 1 is inserted and held by measuring pieces 8, 9, and rotated in the direction Y at a constant speed through a drive plate 5, contact points (m), (n) of the measuring pieces 8, 9 and the fitting part move at a constant angular velocity in the direction as indicated with an arrow Z. At this time point, a radius vector D1 is stored in a memory part. Subsequently, when the point (m) comes to a position (a), the size of a shaft diameter is reduced, a difference between said size and D1 is detected by an arithmetic comparator part, and in its state, its measurement is not executed. Subsequently, at the point where the point (m) passes through an angle beta, it enters a measuring range A, and the roundness in a circular section containing a key groove 1b is measured. A shaft diameter D2 of a circular section containing no key groove 1b si detected by detecting heads 9, 9 and the roundness is measured.
