[0002] Magnetic particle testing of cylindrical end faces is a method commonly used to detect surface defects on the end faces of cylindrical workpieces, especially for the detection of surface and near-surface cracks, scratches, corrosion and other defects in metal materials. This method uses the distribution characteristics of magnetic powder under the action of a magnetic field to display the location and shape of defects.

When the shell 809 moves, the fixed rod 808 and the sliding bar 810 can limit the shell 809 to prevent the shell 809 and the ultraviolet lamp 804 from rotating when adjusting. The notch 803 can increase the friction between the hand and the threaded ring 802 to prevent sliding when the threaded ring 802 is rotated.

[0037] When it is necessary to install the lower end surface yoke 711, the lower end surface yoke 711 is pulled to move, and then the lower end surface yoke 711 drives the fixing plate 92 to move, and the fixing plate 92 drives the connecting block 94 to move, and then the connecting block 94 is aligned with the connecting frame 93, and then the connecting block 94 is inserted into the connecting frame 93, and then the insertion rod 96 is pulled to move, and the insertion rod 96 is inserted into the connecting block 94 and the connecting frame 93 for fixing. When it is necessary to insert the insertion rod 96 for fixing, the insertion rod 96 is pulled to drive the spring 97 to stretch, and then the insertion rod 96 is aligned with the connecting block 94 and the connecting block 94, and then the insertion rod 96 is released. The spring 97 is contracted to drive the insertion rod 96 to be inserted and fixed. When it is necessary to pull the insertion rod 96, the connecting rod 91 can be directly pulled, and the connecting rod 91 drives the two insertion rods 96 to move. The connecting rod 91 makes it more convenient to move the insertion rod 96, and the anti-slip sleeve 95 can increase the friction between the hand and the connecting rod 91 to avoid sliding when pulling the connecting rod 91.
