摘要： An X-ray inspection system for manually or automatically performing digital fluoroscopy inspections and/or computed tomography inspections by X-ray examination of manufactured parts incorporates a computer system which automatically analyzes the inspected parts for flaws. The system includes apparatus for automatically positioning the parts in an X-ray machine for obtaining fluoroscopy and tomography views of the part and for acquiring data from the inspections at production rates. The system automatically identifies the location of rejectable flaws in the parts during the fluoroscopy scanning and subsequently identifies those locations for obtaining tomography scans, if the identified flaw location is questionable. The system can automatically reject parts containing flaws identified during the fluoroscopy inspections. This system operates in a real-time environment by providing analysis of one part while a subsequent part is being subjected to X-ray examination. The data obtained during each examination is archived and stored for tracking the part in further manufacturing processes.

摘要： A manipulator for positioning a part includes a manipulator mandrel, manipulator arms, a pneumatic actuator ball plunger, drive motors, and shaft encoders. The motors drive the manipulator mandrel vertically perpendicular to a plane of directed X-ray beams and one whose rotation axis is vertical and perpendicular to the plane of the directed X-ray beam. The motors include positioning encoders which generate encoding pulses representative of movement of the manipulator mandrel along either axis. The pneumatic ball plunger provides for the acquiring of a gripper which holds a part to be inspected in the X-ray beam. The manipulator mandrel includes two L-shaped arms inwardly extending towards the ball plunger for acquiring a gripper having outwardly extending flanges.
