Instrument for measuring the bending radius of convex pieces of different diameters

摘要

Cylindrical part`s radius of curvature measuring device has a cradle formed of two homothetic wings that define a support angle whose bisector is formed by a tubular body (1). A plunger (5) is in the tubular body and is movable in rotation and in axial translation in a zone delimited by a fine stopper (8). The plunger is integrated to a graduated dial (12) moving in rotation with respect to a reading index representing a fixed flange (14) extending the body.
