Abstract

PURPOSE: To enable breakage of a pin to be detected certainly by forming the blind hole which introduces fluid into the positioning pin for a work, permitting communication with the air through this hole when the top edge of the pin is broken.
CONSTITUTION: A blind hole 10C which communicates to the lower end along the axis line of the positioning pin 10 for a work 16 is drilled, and fluid is introduced into the hole through fluid passages 20, 12a, and 12b from outside. When, the top edge of the positioning pin 10 is broken, fluid communicates to the outside air, and the variation of the negative pressure is detected by a pressure sensing element etc., and a lamp etc. are lighted up.
