ABSTRACT:
A measurement apparatus (10) for measuring a dimension between two surfaces (26, 27) on a workpiece (20) in which the apparatus includes a pair of gaging tips (310, 320) for engaging the surfaces. The gaging tips are mounted toward the end of a spindle (120) and extend outwardly (perpendularly) therefrom. The gaging tips (310, 320) are moved inwardly by the surfaces (26, 27), with the amount of inward movement being dependent on the distance between two surfaces. The inward movement of the gaging tips is sensed by a one piece flexible member (200), preferably in the shape of an "H", which has parallel legs (230, 240) compressed and pivoted about its central portion (250) by the inward movement of said tips. The flexible member is mounted rewardly of the contact tips by a thin pivot portion (224) to a housing. A transducer (400) mounted within the housing and coupled to one of the arms of the flexure member measures the pivoting displacement of the other arm, and thus the flexure as a result of the compression by the gaging tips, thereby measuring the dimension between the two surfaces.
