Nuclear fuel rod end plug weld seam online detection device and method

The invention relates to an X-ray digital imaging detection device and method which are used for detecting a weld seam of an end plug of a nuclear fuel rod. The device comprises a conveying mechanism which is used for assisting a nuclear fuel rod in automatically entering and exiting from the X-ray digital imaging detection device; a clamping and rotating mechanism which is used for rotating the nuclear fuel rod so as to image the whole circle of a weld seam of an end plug of the nuclear fuel rod in the detection process of the nuclear fuel rod; an X-ray machine mounting mechanism in which an X-ray machine for emitting X-rays is mounted; and a flat panel detector mounting mechanism in which a flat panel detector is mounted, the flat panel detector being matched with the X-ray machine to image the end plug of the nuclear fuel rod. 本发明涉及一种X射线数字成像检测装置和方法，其用于检测核燃料棒的端塞的焊缝，该装置包括：输送机构，其用于辅助核燃料棒自动进入和退出所述X射线数字成像检测装置；夹持旋转机构，其用于旋转核燃料棒，以在核燃料棒的检测过程中，对核燃料棒的端塞的焊缝的整个一周实现成像；射线机安装机构，其中安装有发射X射线的射线机；平板探测器安装机构，其中安装有平板探测器，用于与射线机配合
