Abstract
A gauging apparatus for making at least one displacement measurement comprises an elongated flexure member having a pair of spaced apart and substantially parallel body sections. Each body section has an extending portion for contacting a workpiece to be gauged and movable from one position to another corresponding to a displacement measurement. Spaced apart and substantially parallel top and bottom sections join the parallel body sections forming a unitary flexure member having a central opening. The flexure member includes a plurality of webs formed by a sufficiently thin section of material so as to form a hinge. Each of the parallel body sections include a pair of spaced webs for permitting the top and bottom sections to move in parallel motion. The bottom section includes an additional pair of web for permitting movement of the respective extending portions toward and away from each other and a proportional movement of the bottom section in response to such movement of the respective extending portions. At least one strain gauge is operably associated with the bottom section for sensing movement thereof.
