Abstract

PURPOSE: To enable a correct phase indexing operation without providing any special machine or means by a method wherein an outer circumferential surface of a crank pin is abutted against a side contact piece arranged in a rest device so as to allow a phase indexing operation for the crank shaft.
CONSTITUTION: Indexing driving device is installed on an index table 1 of a grinder machine. When a grinding operation is started, a driving pin having a driving plate with a reference hole for the crank shaft 55 is engaged. Upon starting an operation of the first crank pin P1, a main body of the rest device 27 is moved in a forward direction with an operation of the cylinder mechanism 28 of the rest device 25, thereby both the lower surface contact piece 34 and the side surface contact piece 36 are moved fast in a forward direction up to the fore-most forwarding movement. Then, the piston is moved in a rearward direction under an operation of the cylinder mechanism of the indexing driving device, the shaft 55 is rotated in a clockwise direction, an outer circumferential surface is abutted against the leading end surface of the contact piece 36, thereby a correct phase indexing operation is completed.
