GAUGE ASSEMBLY FOR SWAGING CHECK OF CYLINDRICAL MEMBER AND MEASURING METHOD OF SWAGING

摘要

PURPOSE: To test the acceptability of swaging work by providing means for aligning a tubular member and a bore and limiting the moving range of tubular member in the bore. CONSTITUTION: A gauge can determine whether a swaged member (tubular member) 120 is within an allowance by an arrangement wherein the coupling nut 110 of a fitting B and the ferrules (single or a plurality) 122, 124 thereof engages a piston 90 and the tubular member 120 is pushed into a gauge member along with the piston 90. More specifically, a nut 110 is tightened by fingers and screwed over the piston 90. Consequently, the ferrule 122 engages the tapered mouth face 96 of piston 90 and the member 120 is prevented from slipping farther into a piston hole 94. Subsequently, the swaged assembly and piston 90 are pushed into the base 80 of gauge and a dial gauge is read out. According to the method, acceptability of swage of a tubular member can be determined.
