STUD FOR A MOVABLE GAGING ELEMENT AND ITS COMBINATION WITH THE GAGING ELEMENT AND WITH A GAGE

摘要

A gage includes a gaging element mounted for movement on a gaging axis diametrically of the test part and a relatively fixed cooperating gaging means. The position of the movable gaging element with a test part in the gage is indicated by an indicator and measures or compares the diameter of the test part with a master part. The stud to be described is constructed with an outer member having a bore which receives an inner member. The inner member is anchored to a gage frame. The outer member has pin means of one or more pins secured thereto which pin is slidable in a hole in the inner member with a range of movement of the inner member with respect to the outer member at least a little more than the tolerance limit of the test part. With the stud herein there can be no cocking of the gaging element and hence a more accurate reading is secured. The invention also includes the combination of the stud with a gaging element and also with a gage having a movable gaging element mounted on the stud and a cooperating gaging means.
