Description

Technical Field

[0001] The utility model relates to the technical field of magnetic powder detection, in particular to a coil-type magnetic powder detection auxiliary device. Background Art

[0002] Currently, coil-type magnetic particle testing is used for steel pipes, cylindrical shafts, bolts and other parts. It can inspect the workpiece 360 ​​degrees. The on-site inspection process usually requires the cooperation of multiple people.

[0003] For example, the current inspection process for small bolts involves standing the bolt upright and spraying a magnetic suspension solution with a spray bottle. A handheld magnetic particle inspection coil is then swept up and down the bolt to detect surface defects. While a single person can inspect small bolts, the inspection requires a 360-degree observation around the bolt.

[0004] Taking steel pipes, cylindrical shafts, bolts and other parts of about one meter in length as an example, at least two inspectors are required to cooperate. One person holds the steel pipes, cylindrical shafts, bolts and other parts upright, and the other person holds a spray bottle and a magnetic powder inspection coil to detect defects. It is not easy to apply magnetic suspension to the top of the steel pipes, cylindrical shafts and bolts, and the inspectors need to look up to inspect and observe.

[0005] Taking a 7- or 8-meter-long steel pipe as an example, the steel pipe is placed horizontally. When inspecting the ends of the steel pipe, two inspectors can cooperate in the inspection. When the middle position of the steel pipe is inspected, due to the weight of the steel pipe, multiple people may be needed to assist in lifting and rotating the steel pipe. Otherwise, it will be difficult for the inspector holding the magnetic powder inspection coil to see the lower surface of the steel pipe when it is lifted horizontally.

[0006] In summary, the current detection method has the following defects:

[0007] 1. Multiple people are required to cooperate in the test, and the spray bottle needs to be rotated during the test. It is easy for the spray bottle to apply the magnetic suspension unevenly, and the top is dry and the bottom is wet after application, which affects the test efficiency and quality.

[0008] 2. During the inspection, the inspection piece needs to be rotated 360 degrees. For some round steel ingots and rotating shafts, which are heavy and inconvenient to rotate, the inspection continuity is affected and it is easy to cause missed inspections.

[0009] 3. Manually rotating the test piece requires a lot of manpower and is very hard work. There are also certain safety risks in the test. Utility Model Content

[0030] In this embodiment, the flip roller device 20 is used to flip the part to be inspected so that the magnetic suspension spraying device 40 can spray the surface of the part to be inspected in all directions. The flip roller device 20 includes a first horizontal flip roller device 21 and a second horizontal flip roller device 22 with the same structure, and also includes a rotating ball device 23. The rotating axis of the rotating ball device 23 is horizontally arranged, and the first horizontal flip roller device 21 and the second horizontal flip roller device 22 are symmetrically arranged with the rotating ball device 23 as the center. In addition, the rotating axes of the first horizontal flip roller device 21 and the second horizontal flip roller device 22 are horizontally arranged. Among them, the spatial position height of the first horizontal flip roller device 21 and the second horizontal flip roller device 22 is higher than the position height of the rotating ball device 23, so that the rotating ball device 23 applies force from the bottom, and the first horizontal flip roller device 21 and the second horizontal flip roller device 22 apply force from the side to flip the part to be inspected.

[0031] In this embodiment, the moving roller device 30 is used to move the part to be inspected, transporting it to the position of the magnetic suspension spraying device 40 and passing it through the magnetic powder detection coil 50. The moving roller device 30 includes a first moving roller device 31 and a second moving roller device 32 with the same structure, and the first moving roller device 31 and the second moving roller device 32 are symmetrically arranged with the rotating ball device 23 as the center. The spatial position height of the first moving roller device 31 and the second moving roller device 32 is higher than the position height of the rotating ball device 23. The first moving roller device 31 and the second moving roller device 32 are arranged at an angle, and the rotation axis of the first moving roller device 31 and the rotation axis of the second moving roller device 32 are in a "V" shape.

[0032] In this embodiment, the first horizontal flip roller assembly 21 and the first movable roller assembly 31 are positioned on the same side, with the rotational surfaces of the horizontal flip rollers in the first horizontal flip roller assembly 21 and the movable rollers in the first movable roller assembly 31 aligned, forming a first flip movable side surface. The second horizontal flip roller assembly 22 and the second movable roller assembly 32 are positioned on the same side, with the rotational surfaces of the horizontal flip rollers in the second horizontal flip roller assembly 22 and the movable rollers in the second movable roller assembly 32 aligned, forming a second flip movable side surface. Specifically, the first flip movable side surface and the second flip movable side surface also form a "V" shape, facilitating flipping and moving the test piece.

[0033] In this embodiment, the magnetic suspension spraying device 40 is suspended on the support platform 10 by a bracket 42. The magnetic suspension spraying device 40 includes a magnetic suspension spraying pipe 41. The spraying port of the magnetic suspension spraying pipe 41 is toward the rotating ball device 23, and one end of the magnetic suspension spraying pipe 41 is connected to the magnetic suspension storage tank (not shown in the figure) through a hose, and the other end is provided with a residual liquid collection hole (not shown in the figure), and the residual liquid collection hole is connected to the liquid recovery tank (not shown in the figure) through a hose. Specifically, the axis of the magnetic suspension spraying pipe 41 is parallel to the rotation axis of the rotating ball device 23 and highly aligned so that the magnetic suspension is evenly sprayed on the surface of the workpiece to be tested. Magnetize the workpiece to be tested.

[0034] In this embodiment, the annular surface of the magnetic powder detection coil 50 faces the transmission direction. Specifically, the center of the magnetic powder detection coil 50 is horizontally aligned with the axis of the rotating shaft of the rotating ball device 23. During detection, the magnetic powder detection coil 50 is powered on, and the test piece wrapped in magnetic suspension passes through the magnetic powder detection coil 50, forming a magnetic field. After the test piece is magnetized, the presence of discontinuities causes local distortion of the magnetic lines of force on the surface and near the surface of the test piece, generating a leakage magnetic field. This attracts the magnetic powder applied to the surface of the test piece, forming a visually visible magnetic mark under appropriate lighting, thereby showing the location, size, shape, and severity of the discontinuity and enabling defect detection of the test piece.

[0035] In this embodiment, the coil-type magnetic powder detection auxiliary device includes a controller, which is communicated with the flip roller device 20 and the movable roller device 30. Specifically, the controller is connected to the drive motor in the flip roller device 20 and the movable roller device 30 to control the direction and speed of the rollers in the flip roller device 20 and the movable roller device 30.

[0036] In this embodiment, the first horizontal flip roller device 21, the second horizontal flip roller device 22, the first moving roller device 31, and the second moving roller device 32 are all rotating rollers on an actual factory assembly line, but with different assembly postures, respectively achieving the flipping and conveying of the test piece. The rotating ball device 23 is also an existing device, mostly used on flexible substrate production lines. Flexible substrates are prone to wrinkling during conveyance, and if the substrate width is too wide, there will be slack in the middle. Using the spherical structure, the flexible substrate can be flattened, raised, and tightened. The flip roller device 20, the moving roller device 30, and the magnetic powder detection coil 50 are all mature products available on the market. The controller is, for example, a PLC control system.
