A film clamping anti-mistouch device for radiographic flaw detection

Abstract

A film clamping anti-mis-collision device for radiographic flaw detection belongs to the technical field of industrial flaw detection. Connected with the execution end of the manipulator, the two ends of the installation base are rotationally connected with the overturn frame through the overturn drive mechanism, the installation base and the overturn frame enclose a clamping space for clamping the film, and the bottom of the installation base is clamped with the film through the clamping mechanism connected, the installation base and the overturning frame are provided with detection parts to prevent accidental contact of the film during the process of taking and placing the film. During the release process, the problem of accidental contact between the film and the workpiece is avoided, and the safety of the operation is improved.

Description

technical field [0001] The invention relates to the technical field of industrial flaw detection, in particular to a film clamping anti-collision device for radiographic flaw detection. Background technique [0002] At present, the field of flaw detection mainly uses high-energy rays and sound waves to determine whether the object is defective or not by irradiating the object and then presenting its internal structure on the film. Among them, radiographic inspection is a frequently used inspection method. Commonly used rays are X-rays and gamma rays. X-rays and γ-rays can pass through metal materials to varying degrees and produce photosensitive effects on photographic films. Using this performance, when the ray passes through the object to be inspected, due to the difference in the absorption capacity of the ray by the internal defects of the object, the intensity of the ray falling on the film is different, and the sensitivity of the film is also different, so that accur...

Problems solved by technology

In the actual production process, due to the existence of radiation, when a position is detected, only after the radiation dose in the detection environment reaches the index of human safety can manual operation be performed, which not only reduces the efficiency of detection, but also cannot be continuously There are also radiation safety issues for operators

Moreover, in the process of flaw detection, it is necessary to move the tooling carrying the film to a position a certain distance away from the lower surface of the workpiece to be inspected, but the movement of the tooling is usually performed manually, and the tooling often touches due to careless operation. Workpiece, so that both the film and the workpiece are damaged to varying degrees, thus affecting the accuracy of the test results
