Abstract
The inspection apparatus self-adjusts for inspecting bolt-holes of a predetermined size range between a minimum inspection diameter and a maximum inspection diameter. A probe shaft is coupled through a ramp portion to a pear-shaped probe head. The probe head includes a sensor element at the perimeter thereof. An axial slot extends through the shaft and the probe head, dividing the probe head into two probe head sections. A first spring couples the probe head sections and normally urges the sections away from each other and toward the maximum inspection diameter. A cup is slidably positioned around the ramp portion such that, as the cup slides along the ramp portion toward the probe head, the two probe head sections are urged together and the minimum inspection diameter is approached. A second spring is positioned about the shaft to normally urge the cup to an extreme position along the ramp portion, resulting in the minimum inspection diameter.
