The problem.
Description
technical field [0001] The invention relates to a device and method for automatic imaging magnetic particle flaw detection of railway axles, belonging to the technical field of magnetic particle flaw detection in nondestructive testing. Background technique [0002] At present, the magnetic particle flaw detection of railway vehicle axles is still used to observe the magnetic marks on the magnetized axle body, journal, and wheel web with human eyes, and make judgments on the display of magnetic marks based on work experience and give conclusive opinions way of doing. From the actual implementation, it can be found that this traditional magnetic particle inspection method has the following defects: [0003] 1. The detection speed is slow and the work efficiency is low. [0004] 2. High labor intensity, repetitive, monotonous, and unchanging workflows bring serious visual fatigue to flaw detectors, which will lead to problems such as simplified processes, omissions, missed d...
