Abstract: A rapid detection tool for a coaxial relationship based on a photosensitive material and a detection method using the same are used to detect coaxiality of two through-holes in the same workpiece to be detected. An image processing unit and a control unit are mounted outside a light-shielding box. Light sources, cameras, sensors, and an air cylinder are mounted in the light-shielding box. A photosensitive plate coated with a photosensitive resin is placed between the two holes, and two sides are irradiated by the light sources. Coordinates of centers of circular patterns formed on the photosensitive plate are calculated so that a coaxial relationship between the two holes can be accurately obtained. An output rod of the air cylinder is controlled to extend outward to reject a workpiece to be detected not meeting requirements.
