Description

Technical Field

[0001] This utility model relates to the field of flaw detector technology, and in particular to a flaw detector equipped with an automatic magnetic powder light-blocking mechanism. Background Technology

[0002] Magnetic particle testing, as an important non-destructive testing method, plays a crucial role in many industrial fields. In the machinery manufacturing industry, for various parts such as shafts, gears, and bolts, magnetic particle testing can accurately detect surface and near-surface defects such as cracks and porosity, ensuring product quality and avoiding safety accidents caused by component failure. Therefore, it is necessary to design a flaw detector equipped with an automatic magnetic particle light-shielding mechanism.

[0003] Existing flaw detectors have several shortcomings in their light-shielding design. Some traditional flaw detectors use manual light-shielding methods, such as manually covering the surface with a light-shielding cloth or manually adjusting the position of the light-shielding cover. This manual operation requires extra time for light-shielding preparation before each flaw detection operation. Especially in continuous flaw detection operations, frequent manual operation not only reduces flaw detection efficiency but also easily distracts the flaw detection personnel, affecting the continuity of work. Pushing the light-shielding window to the appropriate position quickly and effectively blocks external light from entering the flaw detection observation area. Compared with manual light-shielding methods, this method greatly saves operation time, improves flaw detection efficiency, and allows flaw detection work to proceed more smoothly. Furthermore, the clamping structure can firmly fix the workpiece, ensuring that the workpiece remains stable during flaw detection and avoiding interference from flaw detection results due to workpiece movement or shaking. This structure has good versatility and adaptability, and can be flexibly adjusted according to the shape, size, and material of different workpieces to achieve reliable clamping of various types of workpieces, effectively improving the work efficiency, accuracy, and applicability of magnetic particle flaw detection equipment.
