Abstract

PURPOSE: To make precise positioning of a crank shaft even if the diameter of a reference hole is dispersed, by eliminating the play between the reference hole and a positioning pin by distributing the play to both sides at the pin center.
CONSTITUTION: The second element 33 of a positioning pin 10 is horizontally moved by a plunger 37 due to a force of a spring 38, and a reference hole Wh is positioned concentrically with the center of the pin 10 by pressing the contact points 33a, 33b to the inner surface of the reference hole. When a cylinder 35 is provided with pressure oil, a piston 36 turns the second element 33 rightward to form a clearance between the pin 10 and the hole Wh. Then a shaft ring 19 is activated in this state by means of a cylinder 22 and the positioning pin 10 can be set to the hole Wh. Since the reference hole can always be positioned concentrically to the positioning pin despite the dispersion of the hole, the accuracy of positioning is much improved.
