Description

General crossbeam steel pipe type framework magnetic powder flaw detection positioning tool Technical Field The utility model relates to the technical field of nondestructive testing, in particular to a general beam steel tube type framework magnetic powder inspection positioning tool. Background In the process of vehicle manufacture and maintenance, in order to ensure the quality of welded parts or structural parts of a framework, nondestructive detection is usually required to be carried out on the framework, and magnetic powder inspection is taken as one of common detection means and is widely used for detecting defects on the surface or near surface of a steel structure. In the magnetic particle inspection process, in order to ensure the inspection accuracy, the frame to be inspected needs to be stably supported and positioned so as to maintain the consistency of the posture of the member. In the magnetic powder inspection process of the existing vehicle framework, the existing positioning tool is usually customized for specific vehicle types because of large structural size difference of the frameworks of different vehicle types, cannot flexibly adapt to detection requirements of different frameworks, and therefore the tool is frequently replaced, and stability and operation efficiency of inspection results are affected.
