Description

Technical Field

[0002] Fluorescent magnetic particle flaw detection online detection devices are usually used to detect defects on metal surfaces, especially in the manufacturing or maintenance process, to monitor in real time whether the material has cracks, holes or other surface defects. The working principle of the fluorescent magnetic particle flaw detection online detection device is to magnetize the workpiece through electric current or permanent magnets, so that the magnetic lines of force near the defects of the workpiece change, so that the magnetic powder can gather at the defects. The staff sprays magnetic powder with fluorescent properties on the surface of the workpiece. These magnetic powders can emit fluorescence under ultraviolet light and gather in the defect area for easy observation. The staff then uses ultraviolet light to illuminate the inspection area to make the magnetic powder produce fluorescence. The image is captured in real time by the camera, and the inspection personnel can observe the possible defect location. Finally, the staff transmits the image information to the computer system for processing to locate, classify, record and analyze the defects.

[0028] The working principle of the present invention is as follows: When the fluorescent magnetic particle flaw detection online detection device of this embodiment is used, the staff transfers the workpiece 16 to the limit plate 32. Through the elastic potential energy of the limit spring 34, the limit plate 32 moves along the length direction of the slide slot 11 driven by the slider 31 until the side walls of the two limit plates 32 abut against the end of the workpiece 16, and then the driven wheel 63 is fixed to the workpiece 16 by bolts.

At this time, the staff starts the spray part 23, and the magnetic powder sprayed by the spray part 23 contacts the side wall of the workpiece 16 after passing through the discharge hole 22.

[0029] When the staff starts the driving cylinder 444, the piston rod of the driving cylinder 444 is extended and retracted to drive the driving rod 443 to move, thereby driving the driving shaft 441 to move along the length direction of the rotating groove 13, and then driving the rotating rod 43 to move synchronously. At this time, the driving spring 442 is in a stretched state. Through the elastic potential energy of the driving spring 442, the extension length of the driving spring 442 in the vertical direction far exceeds the moving distance of the rotating plate 2 along the length direction of the transmission plate 41, so that the rotating rod 43 moves in the horizontal direction and rises and falls in the vertical direction at the same time, so that the rotating plate 2 rotates synchronously around the end of the transmission plate 41, thereby adjusting the position of the discharge hole 22 on the rotating plate 2, so that the spray part 23 in the transmission groove 21 sprays magnetic powder and moves synchronously, so that the magnetic powder is fully in contact with the workpiece 16, so that it is not easy to have parts on the workpiece 16 that are not in contact with the magnetic powder, thereby improving the accuracy of the detection of the workpiece 16.
