Filed: 1985-10-09
Abstract: PURPOSE:To perform the positional setting of a probe within a short time, by utilizing centrifugal force acting on the ultrasonic probe mounted on a cylinder and suppressing the operation of the ultrasonic probe ready to fly out from the center of rotation to the outside by the striking surface of a guide part. CONSTITUTION:A cylinder 3 rotates around a material 1 to be inspected and guide parts 10 indivisually slidable along the center of rotation of said cylinder 3 are mounted on the cylinder 3. A striking surface, on which an ultrasonic probe 2 strikes when moves to an outer side part by centrifugal force, is provided to each of the guide parts 10. When the guides parts 10 are rotated with respect to the cylinder 3 along a support part 12, the relative position of the striking surface 11 and the probe 2 changes. Subsequently, when the cylinder 3 begins to rotate, the probe 2 begins to move to the direction separated from the center of rotation of the cylinder 3 along a slide part 14 and strikes on the striking surface 11 to hold a predetermined distance between the probe 2 and the material 1 to be inspected. By this method, the setting of the distance between the probe and the material to be inspected can be performed within a short time.
