Background
The nondestructive testing is a method for inspecting and testing the structure, the property, the state and the type, the property, the quantity, the shape, the position, the size, the distribution and the change of the defects inside and on the surface of a test piece by taking a physical or chemical method as a means and by means of modern technology and equipment and by utilizing the change of the reaction of heat, sound, light, electricity, magnetism and the like caused by the abnormal structure or the existence of the defects of a material on the premise of not damaging or not influencing the service performance of the tested object and not damaging the internal tissue of the tested object.
The X-ray nondestructive test utilizes the interaction of X-rays with substances during the process of penetrating the substances, and the intensity is weakened due to absorption and scattering. The degree of intensity attenuation depends on the attenuation coefficient of the substance and the thickness of the radiation that passes through the substance. If the transillumination object (the test piece to be tested) has a defect locally and the attenuation coefficient of the substance constituting the defect is different from that of the test piece body, the intensity of the transmitted radiation in the local area is different from that in the surrounding area. And placing the film on the back of the position of the transilluminated test piece to make the film sensitive under the action of the transmitted rays, and processing the film in a darkroom to obtain the negative film. Because the intensities of the transmitted rays of the defective part and the intact part are different, the corresponding part on the negative film has the difference of blackness, and the internal defect condition of the material is judged according to the blackness difference.

As shown in fig. 2, when measuring distance, the driving motor 226 drives the telescopic rod 225 to extend to move the laser probe 222 to the axis of the ray window 212, so as to ensure that the laser beam emitted by the laser emitter can be consistent with the axis of the X-ray central ray beam generated by the X-ray generator 211a, thereby ensuring the measurement accuracy; the laser beam emitted by the laser emitter is reflected by the surface of the object to be measured and then received by the laser receiver, and the laser ranging module 223 calculates the distance between the laser probe 222 and the surface of the object to be measured according to the photoelectric signals of the laser emitter and the laser receiver, and calculates the distance between the laser probe 222 and the surface of the object to be measuredThe distance is displayed on the display screen 224, and since the laser ranging module 223 performs distance measurement according to the photoelectric signals of the laser transmitter and the laser receiver, which is a conventional technique in the art and is also a conventional function of the laser range finder 22, the detailed description thereof is omitted in this embodiment; if the distance between the laser probe 222 and the surface of the object is f, the distance between the laser probe 222 and the X-ray generator 211a when the laser probe is located in the ray window 212 is f0If the distance between the surface of the object to be measured and the film is b, the focal length F to be measured is F + F0+ b, due to practical application f0B is a fixed distance, so the focal length of film exposure can be obtained only by measuring the distance f between the laser probe 222 and the surface of the object to be measured, and an arithmetic module can be arranged, wherein the arithmetic module can adopt an arithmetic circuit and can calculate and form a focal length signal of film exposure according to the measured distance signal between the laser probe 222 and the surface of the object to be measured; as shown in fig. 3, after the distance between the laser probe 222 and the surface of the object is measured, the driving motor 226 drives the telescopic rod 225 to contract, so that the laser probe 222 moves to be close to the inner wall of the radiation window 212, which can prevent the laser probe 222 from blocking X-rays and generating latent images on the film, and ensure that the imaging quality of the film is not reduced.

When the laser ranging is performed, the camera 229 can shoot the detection surface and the laser irradiation position of the object to be detected, and since the X-ray and the laser beam are coaxially arranged, the irradiation position during the laser ranging is the nondestructive detection position, so that the camera 229 can shoot an image to retain the surface condition and the nondestructive detection position of the object to be detected. Moreover, because the laser beam adopts visible light, the light spot emitted by the laser beam can be used for aligning the X-ray with the corresponding detection point on the object to be detected when the X-ray machine 21 detects, the nondestructive detection position can be quickly and accurately obtained, and the acquisition precision of the nondestructive detection position can be ensured.
