Abstract

PURPOSE:To enable accurate and easy measurement of the concentricity between a large-diameter hole and a successive small-diameter hole regardless of the skill of a person by fixing a gauge supporting pipe to be screwed or fitted into the large hole at one end of a holder of the measuring gauge while an indicator is fastened to the other end thereof separately. CONSTITUTION:A male thread 5 is cut in the circumference of a gauge supporting pipe fixed at one end of a holder 1 in such a manner as to be screwed into a female-threaded hole 4 of a stepped hole 4 in a matter 3 to be measured. When the gauge supporting pipe 2 is screwed into the hole 4a, a measuring piece 6a of a measuring element 6 comes into contact with the surface to be measured to measure the concentricity between the hole 4a and the successive small diameter hole 4b. In other words, a dial gauge 9 is fixed at the other end of the holder 1 and the head of the measuring element 6 gets into contact with a contactor 13 provided at the tip of a spindle 12 to turn a pointer 14. As the spindle 12 retracts, the pointer 14 swings. The swing is read to check whether the value is within an allowable range or not thereby enabling accurate and simple measurement of the concentricity.
