JPS5788301A - Inspecting device for hole diameter - Google Patents

Abstract

PURPOSE:To make efficient inspection of multiple perforated plates possible by using a holding table studded thereon with a required number of gage pins which are worked at leading end parts in a way as to be easily inserted into the holes to be inspected, and are so arranged to be oscillated by a required extent on a horizontal plane. CONSTITUTION:An object to be inspected which is pierced with plural holes to be inspected perpendicularly to a reference plane is held horizontally in such a way that said reference plane comes on the lower side and a holding table studded with a required number of gage pins which are worked at leading end parts in a way as to be inserted easily into the holes to be inspected and are so arranged as to be oscillated to a required extent on a horizontal plane is disposed opposite thereto, and the relative positions of both are brought into proximity to penetrate the gage pins into the holes to be inspected, whereby thes imultaneous inspection of all the hole diameters is accomplished. For example, upper, lower supporting plates 2, 3 holding a required number of gage pins 1 worked at both ends to a circular cone shape in a way as to oscillate these horizontally by a required extent are disposed below a plate 100 to be inspcted having multiple holes 101 to be inspected and the supporting plates are moved upward by the operation of a lever 82, so that the pins are penetrated through the holes to be inspected.
