Problems solved by technology
The disadvantages of doing this are: 1. It takes a long time and the work efficiency is extremely low, which is not conducive to the detection of large quantities of test pieces.
2. Inaccurate positioning and low precision
3. There are many auxiliary materials, which is not conducive to the environmental protection, sanitation and cleanliness of the testing environment, and the acquisition of auxiliary materials is not convenient enough
When the height of the test piece to be tested is relatively large, it is also necessary to adjust the height of the ray flaw detector. During the adjustment process, it is also necessary to ensure that the ray can effectively penetrate the metal to be tested, so it is very inconvenient to adjust, and the adjustment efficiency is low. Inaccurate, seriously affecting the detection effect

The invention discloses a supporting and fixing device for a test specimen, particularly discloses a supporting and fixing device for supporting a test specimen of a ray inspection machine, and belongs to the technical field of metal nondestructive testing equipment. The supporting and fixing device for the test specimen of the ray inspection machine provided by the invention is used for conveniently fixing the position of a detected test specimen and rapidly and reliably adjusting the position of the ray inspection machine. The supporting and fixing device for the test specimen comprises an adjustable ray inspection machine fixing rack and a test specimen fixed supporting rack, wherein the test specimen fixed supporting rack is positioned on the periphery of the adjustable ray inspectionmachine fixing rack, and the test specimen fixed supporting rack and the adjustable ray inspection machine fixing rack are connected into a whole.
Description
technical field [0001] The invention relates to a test piece supporting and fixing device, in particular to a test piece supporting and fixing device for a radiographic flaw detector, which belongs to the technical field of metal non-destructive testing equipment. Background technique [0002] In metal non-destructive testing technology, radiographic testing is one of the commonly used methods. Its basic principle is to use the property that the ray can penetrate the metal, so that the ray can pass through the object to be inspected and projected onto the film, and the absorption of the ray by the defective part and the non-defective part The ability is different. If there is no internal defect, the rays passing through the object can make the film exposure uniform, that is, the blackness of the negative film is uniform; if there is a discontinuity in the ray channel, the amount of radiation reaching the film at this place increases, and the negative film is black. degree in...
