Gage for measuring mini-strip displacement for determining intensity

摘要

A gage for measuring deflection of a “mini-strip” used to determine peening intensity in small cavities and crevices of a work piece includes a pair of platforms made of a magnetic material spaced apart in a non-magnetic fixture a distance substantially the same as the length of the mini-strip. The platforms have a diameter slightly larger than the width of the mini-strip to provide support for both corners on each end of the mini-strip. A magnet for each of the platforms may be advanced toward and retracted from the platform to adjust the degree of magnetic attraction of the mini-strip. The platforms are stepped to define a shoulder and posts are offset from one of the platforms which cooperate to guide the user in proper placement of the strip. A plunger extended from the indicator engages the strip at substantially its midpoint, to thereby measure the deflection of the strip to give an indication of peening intensity.
