Description

Technical Field

[0001] This utility model belongs to the field of magnetic particle testing technology, and specifically relates to a magnetic particle testing protective cover. Background Technology

[0002] Magnetic particle testing is a non-destructive testing method specifically designed to detect surface and near-surface defects (such as cracks and inclusions) in ferromagnetic materials (e.g., steel). Its principle involves magnetizing the workpiece to create a leakage magnetic field at the defect location, attracting applied magnetic powder and forming a visible magnetic trace, thus visually displaying the location, shape, and size of the defect. This method is highly sensitive, capable of detecting micron-sized defects, and relatively simple to operate. However, it is only applicable to ferromagnetic materials and cannot detect deep internal defects. It is widely used in the inspection of critical components in aerospace, automotive manufacturing, and petrochemical industries.

[0003] A known authorized patent with application number 202321204570.3 discloses a magnetic particle inspection protective cover, comprising an inspection device body, a slide rail, a connecting frame slidably fitted on the slide rail, and a magnetic particle spray bottle mounted on the connecting frame. Vertical plates are fixedly connected to the left and right sides of the connecting frame, and a protective plate is movably connected between the two vertical plates via a pin. The protective plate is made of transparent material, and a swing rod with a sliding track is provided on the left and right sides of the inner side of the protective plate. A traction rod is provided on the outer side of the connecting frame, and the free end of the traction rod extends into the sliding track of the swing rod and slidably connects to the swing rod. This utility model solves the problem that existing inspection equipment does not have the ability to block and protect against splashed magnetic suspension, causing contamination of the inspector's body and clothing, and making it inconvenient for users to observe the inspection status of the workpiece.

[0004] However, in implementing the relevant technology, the following problems were found in the above technical solution: In actual testing situations, most of the objects being tested are irregular in shape or the testing area is in a protruding or recessed position. When testing different objects, the device does not adapt well to various different testing areas, and the device is too large, which consumes manpower during frequent movement.

[0005] Therefore, a magnetic particle inspection protective cover is proposed to solve the above problems. Utility Model Content

[0006] This invention proposes a magnetic particle inspection protective cover, which solves the problems in related technologies where, in actual inspection situations, most of the objects being inspected are irregularly shaped or the inspection area is located in a protruding or recessed area.

Detailed Implementation

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0021] Implementation Please see Figure 1 -4, A magnetic particle inspection protective cover, comprising: The host component and the protective components mounted on the outer wall of the host component; The main unit includes a handle 1 and a device rod 3 disposed on the lower surface of the handle 1. A connector 2 is provided on one side of the handle 1 for connecting to an external power source. The protective assembly includes a guard plate 7 and a connecting assembly disposed on the upper surface of the guard plate 7. The protective assembly is connected to the equipment rod 3 through the connecting assembly. The outer wall of the protective plate 7 is hinged to a cover plate 13, and both the protective plate 7 and the cover plate 13 are made of transparent acrylic material. The connecting assembly includes a fixing plate 8 fixedly mounted on the upper surface of the guard plate 7 and a threaded sleeve 11 fixedly mounted on the top of the fixing plate 8. The inner wall of the threaded sleeve 11 is threadedly connected to a screw 10. One end of the screw 10 is provided with a contact block 12, which is made of rubber and contacts the setting rod 3. A rotating block 17 is fixedly installed on the upper surface of the guard plate 7. A sleeve block 18 is rotatably connected to the outer wall of the rotating block 17. A rubber contact 20 is fixedly connected to the lower surface of the sleeve block 18. The rubber contact 20 contacts the cover plate 13 and is used to fix the position of the cover plate 13. A contact rod 19 is fixedly connected to the upper surface of the socket block 18 for rotating the socket block 18; A side plate 16 is fixedly installed on the outermost side of the guard plate 7; An extension rod 21 is fixedly connected to the outer wall of the cover plate 13, and the extension rod 21 spans the guard plate 7.

[0022] The technical solution provided in this embodiment is as follows: In use, first place the device rod 3 into the through hole in the middle of the protective plate 7. After confirming the position, rotate the handle 9. Rotating the handle 9 drives the screw 10 to rotate, causing the contact block 12 to move inward through the threaded sleeve 11 connected to it. This ensures that multiple contact blocks 12 contact the device rod 3, thus fixing the handle 1. After fixing, it is ready for use. In use, first connect the connector 2 to the external power supply, then connect the detection head 6 to the external power supply. After the contact point is in contact with the test point, the next step is to rotate the sleeve block 18 and rotate the contact rod 19 to the outside of the guard plate 7. Then, the extension rod 21 is used to open one side cover plate 13. After opening, magnetic powder can be sprayed onto the test point for testing. If the test point is on top and the main unit needs to be used upside down, after opening the cover plate 13 to spray the magnetic powder, the cover plate 13 should be closed immediately. By rotating the sleeve block 18, the rubber contact 20 can be brought back into contact with the cover plate 13. The outer side plate 16 prevents the magnetic powder from flowing out.

[0023] Furthermore, a switch 4 is provided below the handle 1, a hand guard 5 is provided on the lower surface of the handle 1, the switch 4 is located inside the hand guard 5, and a detection head 6 is provided at the end of the equipment rod 3.

[0024] Specifically, by setting the switch 4 inside the hand guard 5, it is ensured that during operation, the burrs on the detection area or the guard plate 7 itself will not come into direct contact with the hand, thus ensuring the safety of the equipment during operation and preventing injury to personnel.

[0025] Furthermore, a rotating handle 9 is fixedly provided at the other end of the screw 10 for rotating the screw 10.

[0026] Specifically, by rotating the handle 9, when it is necessary to connect the guard plate 7 to the equipment rod 3, the screw 10 can be rotated by rotating the handle 9, which increases the torque applied to the screw 10 and makes the rotation of the screw 10 easier.

[0027] Furthermore, a support strip 14 is fixedly installed on the inner wall of the guard plate 7, and a cover strip 15 is fixedly installed on one side of the cover plate 13, with the cover strip 15 located above the support strip 14.

[0028] Specifically, the support bar 14 and the cover bar 15 set on one side of the cover plate 13 ensure that the cover plate 13 will not accidentally fall off or flip over when it is placed normally, thus improving the stability of the equipment.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
