Description

Technical Field

[0001] The utility model relates to the technical field of magnetic particle flaw detection, in particular to a special vertical fluorescent magnetic particle flaw detection line for springs. Background Art

[0002] When producing springs, in order to ensure the quality of the springs, it is necessary to detect the springs to avoid damage such as notches on the springs. Generally, the flaw detection is carried out by the method of fluorescent magnetic particle detection. When the magnetic force encounters discontinuities (i.e., defects such as cracks, slag inclusions, pores, etc.) on the workpiece material, a "leakage magnetic field" will be formed, and thus magnetic poles will be generated on both sides of the defect, and the magnetic powder will be adsorbed around the defects such as cracks.

[0003] When the existing fluorescent magnetic particle flaw detection device is in use, it is difficult to spray magnetic powder on the whole spring, so that the damaged parts on the spring cannot attract magnetic powder, and thus cannot be detected. At the same time, magnetic powder will also adhere to the undamaged parts of the spring, which is likely to affect the flaw detection. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defects existing in the prior art, and to provide a special vertical fluorescent magnetic particle flaw detection line for springs.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] To better achieve the above object, the present utility model adopts a further technical solution: a shielding plate is arranged on the side of the placement plate away from the fixed plate, and the shielding plate is fixedly connected to the fixed bracket.

[0008] To better achieve the above object, the present utility model adopts a further technical solution: a fluorescent irradiation lamp is fixedly installed on the fixed plate, and a switch corresponding to the fluorescent irradiation lamp is installed on the fixed plate.

[0009] The advantages of the present utility model are that during the process of spraying magnetic powder, the spring rotates, so that the magnetic powder can be sprayed onto the entire spring, avoiding detection omissions due to the lack of magnetic powder at the damaged part. At the same time, the spring is vibrated to shake off the magnetic powder that is not adhered to the spring due to magnetism, avoiding its influence on flaw detection. Description of the Drawings

After magnetizing the spring, it is placed on the placement plate 4, and the fluorescent magnetic powder is ejected through the fixed nozzles 6 on the fixed plate 5. When there is damage on the spring, the magnetic powder will gather at the damaged area; a rotating structure, a motor 7 is fixedly connected to the top end of the workbench 1, the output end of the motor 7 is fixedly connected to a rotating rod 9, the rotating rod 9 penetrates through the upper end surface of the fixed bracket 2, a fixed sleeve rod 10 is installed on the rotating rod 9, a pressing plate 8 is installed at the bottom end of the fixed sleeve rod 10, and the position of the pressing plate 8 corresponds to that of the placement plate 4. Lift the pressing plate 8 upward, place the spring well, and let the pressing plate 8 press the spring. After the motor 7 is started, its output end drives the rotating rod 9 to rotate, so that the fixed sleeve rod 10 and the pressing plate 8 rotate accordingly, driving the spring and the placement plate 4 to rotate together, so that the magnetic powder can be sprayed on the entire spring; a fixed cavity 11 is opened inside the fixed sleeve rod 10, the rotating rod 9 extends into the inner side of the fixed cavity 11, and the rotating rod 9 is slidably connected to the side wall of the fixed cavity 11. A fixed spring 12 is fixedly connected to the bottom end of the rotating rod 9, and the end of the fixed spring 12 away from the rotating rod 9 is fixedly connected to the lower inner wall of the fixed cavity 11. A vibration structure is arranged on the rotating rod 9; the vibration structure includes a pressing plate 14 fixedly connected to the top end of the fixed sleeve rod 10, and the pressing plate 14 is sleeved outside the rotating rod 9. An installation plate 15 is rotatably sleeved on the rotating rod 9, the installation plate 15 is fixedly connected to the fixed bracket 2 through an installation bracket, a fixed convex block 13 is installed and connected to the bottom end of the installation plate 15, the position of the fixed convex block 13 corresponds to that of the pressing plate 14, and the bottom end of the fixed convex block 13 is hemispherical. When the rotating rod 9 rotates, the positions of the installation plate 15 and the fixed convex block 13 remain fixed, while the pressing plate 14 will rotate together with the fixed sleeve rod 10, so that the fixed convex block 13 continuously presses the pressing plate 14. Cooperating with the fixed spring 12, the pressing plate 14 and the fixed sleeve rod 10 vibrate up and down, driving the pressing plate 8 and the spring under detection to vibrate together, shaking off the magnetic powder on the non-damaged part of the spring to avoid affecting the flaw detection; an adjusting screw is threadedly connected to the installation plate 15, the adjusting screw penetrates through the installation plate 15 and is fixedly connected to the fixed convex block 13, and the position of the fixed convex block 13 can be adjusted through the adjusting screw, so as to adjust the vibration amplitude.

[0016] On one side of the placement plate 4 away from the fixed plate 5, a shielding plate 3 is provided. The shielding plate 3 is fixedly connected to the fixed bracket 2. The shielding plate 3 shields the ejected magnetic powder to prevent the magnetic powder from escaping, and at the same time facilitates the recovery of the magnetic powder. A fluorescent irradiation lamp is fixedly installed on the fixed plate 5, and a switch corresponding to the fluorescent irradiation lamp is installed on the fixed plate 5. After the fluorescent magnetic powder is adsorbed on the spring, the fluorescent irradiation lamp is turned on, and whether the spring is damaged can be judged by the fluorescent trace on the spring.

[0017] When the utility model is in use, first move the fixed sleeve rod 10 and the pressing plate 8 upward to contract the fixed spring 12, and then place the spring to be detected on the placement plate 4. Under the action of the elastic force of the fixed spring 12, the pressing plate 8 fixes and presses the spring. At this time, start the motor 7 and the fixed nozzle 6, and the fixed nozzle 6 ejects the fluorescent magnetic powder. When there is a damage on the spring, the magnetic powder will be adsorbed by the magnetic force at the damaged part. At the same time, after the motor 7 is started, its output end drives the rotating rod 9 to rotate, so that the fixed sleeve rod 10 and the pressing plate 8 rotate accordingly, driving the spring and the placement plate 4 to rotate together, so that the magnetic powder can be sprayed on the whole spring. Moreover, when the rotating rod 9 rotates, the positions of the mounting plate 15 and the fixed convex block 13 remain fixed, while the pressing plate 14 will rotate together with the fixed sleeve rod 10, so that the fixed convex block 13 continuously presses the pressing plate 14. Cooperating with the fixed spring 12, the pressing plate 14 and the fixed sleeve rod 10 vibrate up and down, driving the pressing plate 8 and the spring to be detected to vibrate together, and shaking off the magnetic powder at the non-damaged part of the spring to avoid affecting the flaw detection.
