SIZING DEVICE OF CRANKSHAFT FINISHING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a sizing device of small and simple structure in which any extra load is not applied to a detecting means and measurement contact positions are kept unchanged. ;SOLUTION: The sizing device of a crankshaft finishing machine comprises a supporting table 4 provided so that it can be moved in the forward and backward directions at a position opposed to the crank pin P of a crankshaft S, detecting parts 20 and 21 provided on the supporting table 4 so that it can be displaced two-dimensionally on a plane vertical to the axis of the crankshaft S and an eccentric part 19 which is installed eccentrically on a rotating body 18 rotated in synchronous with the crankshaft S about a rotating axis in parallel with the axis of the crankshaft S in order to use, as a detection part, a revolution of the same diameter in synchronous with the revolving crank pin P and which engaged with that detection part. After a detection means is engaged with the crank pin P, the eccentric part of the rotating body is revolved in synchronous with the revolving of the crank pin P. Thus the diameter of the crank pin P during working is detected while the engagement of the detection means and the crank pin P is maintained.;COPYRIGHT: (C)1998,JPO
