Abstract

PURPOSE:To obtain a flaw detecting device which is excellent in its inspection processing capability, by rotating a detecting head for eddy current flaw detection, around the circumferential or spherical surface of a fixed object to be inspected. CONSTITUTION:A rotary shaft 7 is held at a desired inspecting rotation speed, an operating lever 23 is raised, an chucks 15, 15' are released. Subsequently, an object to be inspected 37 is carried into an inspected object fixed position A, and is fixed. Slide pressure tools 29, 29' provided on the chucks 15, 15' are energized to the side of the object to be inspected 37, lowering the operating lever 23, and 4 pieces of rollers 30 axially supported by the tip of the slide pressure tools 29, 29' are rotated, profiling on the circumferential or spherical outside surface of the object to be inspected 37. In this way, the flaw detection can be executed in a state that a distance between a detecting head 31 of an eddy current inspecting probe provided on the slide pressure tool 29, and the surface to be inspected is kept almost constant. After the inspecting head 31 has made one rotation or more around the outside circumference of the object to be inspected 37, a shifter 17 is raised, the chucks 15, 15' are released, and the next object to be inspected is inspected in the same way.
