ABSTRACT:
An apparatus which inspects a profile of each rod of a bundle of rods assembled in a cluster includes a holding device for holding a rod, a profile detection sensor for detecting the profile of the rod, a reference position setting device for setting a reference position of the rod, a position detection device for detecting an inspection position of the rod with respect to the reference position and a signal processing and display device for processing and displaying signals from the profile detection sensor and the position detection device. Particularly, the profile detection sensor includes a cylindrical shell into which the rod is inserted, a single or a plurality of strain gauge type sensors disposed in the shell and brought into contact with an external surface of the rod to detect the profile of the rod, a drive motor and a mechanism thereof for rotating the shell about the rod and a drive motor and a mechanism thereof for slidably moving the shell in the longitudinal direction of the rod.
