ABSTRACT:
Apparatus for testing the diameter of a cylindrical hole machined in a very thick part, comprising a first support having a central cavity in axial continuation of the hole to be tested and a second support mounted rotatably on the first support and having an axial cavity. A shaft bearing a bore-testing means passes axially through the cavities in the supports. A motor driving the support by means of gearing allows the second support to be angularly oriented with respect to the first, and a second drive allows the shaft to be driven in an axial translation movement. Controls for the first and second drives allow a scan to be made successively of the entire length of the hole along two generatrices of a first plane passing through the axis of the hole and along two generatrices of a second plane passing through the axis of the hole. The invention is particularly applicable to bore-testing the holes of a steam generator tube sheet of a pressurized water nuclear reactor.
