Abstract

PURPOSE:To carry out the phase indexing of a pin journal in simple ways by inserting the pin of an indexing plate installed at the edge part of a crankshaft into the bush of a driving plate and rotatably supporting the driving shaft at the center of the driving plate to the position deflected from the center of the main journal of the crankshaft. CONSTITUTION:When one of the pin journal 5b of a crankshaft 5 is indexed at a grinding position, the driving shaft of an indexing plate driving plate 8 is turned by a previously calculated angle alpha or gamma around the driving center O2 of the indexing plate by a servomotor. Accompanied with this revolution, the indexing plate 7 is turned by an angle theta around the center O1 of a main journal 5a through a pin 7a by a bush 8a installed projectingly from the driving plate 8, and the phase indexing for the pin journal 5b to be ground is carried out. After the indexed pin journal 5b is held by a chuck 3, said pin journal 5b is turned around the working center O3, and the outer peripheral surface is grinding-worked by a grinding wheel 10.
