核燃料ペレツトの端面直角度の自動検査装置。[Claims for Utility Model Registration] (1) In an automatic inspection device that inspects the perpendicularity of the end face of a columnar nuclear fuel pellet with respect to its axis, the nuclear fuel pellet to be inspected is held in a fixed position with the axis as a reference. a holding mechanism; a plate that is provided so as to be able to move toward and away from the end surface of the nuclear fuel pellet held by the holding mechanism, and that tilts according to the degree of inclination of the end surface when pressed against the end surface of the nuclear fuel pellet; An automatic inspection device for the squareness of the end face of a nuclear fuel pellet, comprising: a sensor that detects the inclination of a plate; and a calculation device that calculates the squareness of the end face of the nuclear fuel pellet based on the detected content of the sensor. (2) The sensor is a light reflection type distance sensor that is provided at a fixed position facing the plate and optically measures the change in distance between the plate and the plate when the plate is tilted. An apparatus for automatically inspecting the end face perpendicularity of nuclear fuel pellets as set forth in claim 1, characterized in that it is a utility model.
