Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, specifically a convenient magnetic particle flaw detector for connecting shafts. Background Technology

[0002] With the continuous development of modern industry, the quality and reliability of the connecting shaft, as a key component in the mechanical transmission system, directly affect the operational safety of the entire equipment. During the production and use of the connecting shaft, various defects, such as cracks, pores, and inclusions, are inevitably generated. If these defects are not detected and dealt with in time, they may lead to serious accidents such as breakage of the connecting shaft during operation, causing huge economic losses and safety hazards.

[0003] In many practical testing scenarios, ambient light is often insufficient for clear observation of magnetic traces. Without a dedicated lighting system, inspectors may struggle to see the fine magnetic traces formed by magnetic particles on the surface of the connecting shaft. Existing technologies do not allow for adjustment of the lighting system, preventing the adjustment of the incident angle and intensity of light according to actual conditions, thus failing to achieve optimal illumination. This results in poor contrast between the magnetic traces and the background, increasing the difficulty for inspectors to observe and interpret the magnetic traces. Therefore, we propose a portable magnetic particle flaw detector for connecting shafts. Utility Model Content

[0004] The purpose of this invention is to provide a convenient magnetic particle flaw detector for connecting shafts to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable magnetic particle inspection machine for connecting shafts, comprising:

[0006] The main unit, the magnetization component installed on the main unit, the wires connecting the magnetization component and the main unit, and the lighting lamp installed on the top of the magnetization component;

[0007] An adjustment assembly includes a support plate disposed on the top of a magnetization assembly, a connecting shaft fixedly connected to the support plate, a convex plate disposed on the support plate, a groove formed on the side of the convex plate near the connecting shaft, the connecting shaft being slidably connected in the groove, a top plate fixedly connected to the top of the convex plate, and a lighting lamp located on the top of the top plate;

[0008] The driving assembly includes a fixed base disposed on top of the magnetization assembly, an electric push rod disposed on top of the fixed base, the electric push rod having an inclination angle of 45 degrees, two convex plates disposed, a connecting plate fixedly connected between the two convex plates, and the electric push rod being connected to the connecting plate.

[0009] Furthermore, a connecting seat is provided at the bottom of the connecting plate, a first rotating shaft is rotatably connected to the connecting seat, a connecting piece is fixedly connected to the bottom of the first rotating shaft, and the output end of the electric push rod is fixedly connected to the connecting piece.

[0010] The above technical solution aims to prevent jamming during the movement of the adjustment component driven by the electric push rod.

[0011] Furthermore, a limiting ring is provided on the side of the connecting shaft near the connecting plate, and the size of the limiting ring is larger than that of the sliding groove.

[0012] The above technical solution is adopted: by setting a limit ring, the connecting shaft is limited to prevent it from falling out of the slide.

[0013] Furthermore, a clamping assembly is provided on the top of the top plate near the lighting lamp. The clamping assembly includes a second rotating shaft, on which a torsion spring is provided, and a clamping plate is rotatably connected.

[0014] The above technical solution is adopted: by setting up a clamping component, the lighting lamp is fixed and limited to prevent it from falling off the top of the top plate.

[0015] Furthermore, the host is provided with a limiting component, which includes a limiting plate. A third rotating shaft is rotatably connected between the limiting plate and the host. A magnetic suction plate is provided on the limiting plate. A magnetic suction block is provided on the side of the host near the magnetic suction plate. The magnetic suction plate and the magnetic suction block are magnetically connected.

[0016] The above technical solution allows the magnetization component to be stored and positioned on one side of the main unit by setting a limiting component, making it easy to carry.

[0017] Furthermore, the host is provided with an extension member on the side near the wire, and three extension members are provided.

[0018] The above technical solution allows for the storage of electrical wires by hanging them on the extension piece, preventing them from becoming tangled or knotted.

[0019] Furthermore, a handle is provided on the top of the main unit.

[0020] The above technical solution is adopted: by setting a handle, the device can be easily carried.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting an adjustment component, the angle of light can be adjusted according to the roughness and color of the connecting shaft surface, resulting in a sharper contrast between the magnetic trace and the background. This solves the problem that in many practical testing scenarios, ambient light often fails to meet the requirements for clear observation of magnetic traces. Without a dedicated lighting component, inspectors may find it difficult to see the fine magnetic traces formed by magnetic powder on the connecting shaft surface. Existing technologies do not allow for adjustment of the lighting component, making it impossible to adjust the incident angle and intensity of the light according to actual conditions. This results in suboptimal lighting effects, leading to unsatisfactory contrast between the magnetic trace and the background, and increasing the difficulty for inspectors to observe and judge the magnetic trace.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figures 1-4 As shown, this utility model provides a technical solution: a convenient magnetic particle flaw detector for connecting shafts, comprising:

[0036] The host 1, the magnetization component 2 installed on the host 1, the wire 10 connecting the magnetization component 2 and the host 1, and the lighting lamp 3 installed on the top of the magnetization component 2; the host 1 is equipped with a handle 8 on the top.

[0037] Adjustment component 4 includes a support plate 41 disposed on the top of magnetization component 2, a connecting shaft 42 fixedly connected to the support plate 41, a convex plate 43 disposed on the support plate 41, a groove 44 opened on the side of the convex plate 43 near the connecting shaft 42, the connecting shaft 42 being slidably connected in the groove 44, and a top plate 46 fixedly connected to the top of the convex plate 43, with the lighting lamp 3 located on the top of the top plate 46;

[0038] The drive assembly 5 includes a fixed base 51 disposed on the top of the magnetization assembly 2, an electric push rod 52 disposed on the top of the fixed base 51, the electric push rod 52 having an inclination angle of 45 degrees, two convex plates 43 disposed, a connecting plate 53 fixedly connected between the two convex plates 43, the electric push rod 52 being connected to the connecting plate 53, a connecting seat 54 disposed at the bottom of the connecting plate 53, a first rotating shaft 55 rotatably connected to the connecting seat 54, a connecting piece 56 fixedly connected to the bottom of the first rotating shaft 55, and the output end of the electric push rod 52 being fixedly connected to the connecting piece 56.

[0039] Specifically, when the angle of the lighting lamp 3 needs to be adjusted, the electric push rod 52 is activated to drive the connecting piece 56 to move. The connecting piece 56 drives the connecting plate 53 to move through the first rotating shaft 55. The connecting plate 53 will drive the convex plate 43 to rotate through the sliding groove 44 by the limit of the connecting shaft 42, thereby adjusting the angle of the top lighting lamp 3.

[0040] Furthermore, such as Figure 3 As shown: A limiting ring 45 is provided on the side of the connecting shaft 42 near the connecting plate 53. The size of the limiting ring 45 is larger than that of the slide groove 44. By setting the limiting ring 45, the connecting shaft 42 is limited to prevent it from falling out of the slide groove 44.

[0041] The above solutions also have the problem that the lighting lamp 3 may detach from the top of the top plate 46 during operation, such as... Figure 3 As shown: A clamping assembly 6 is provided on the top side of the top plate 46 near the lighting lamp 3. The clamping assembly 6 includes a second rotating shaft 61, a torsion spring 62 is provided on the second rotating shaft 61, and a clamping plate 63 is rotatably connected to the torsion spring 62. By setting the clamping assembly 6, the lighting lamp 3 is fixed and limited to prevent it from falling off the top of the top plate 46.

[0042] The above solutions also have drawbacks, such as the inability to store the wire 10 and the magnetization component 2, making them inconvenient to carry. Figure 1 and Figure 2 As shown: The main unit 1 is provided with a limiting component 7, which includes a limiting plate 71. A third rotating shaft 72 is rotatably connected between the limiting plate 71 and the main unit 1. A magnetic suction plate 73 is provided on the limiting plate 71. A magnetic suction block 74 is provided on the side of the main unit 1 near the magnetic suction plate 73. The magnetic suction plate 73 and the magnetic suction block 74 are magnetically connected. An extension 9 is provided on the side of the main unit 1 near the wire 10. There are three extensions 9. The wire 10 is hung on the extension 9 for storage. Then the magnetized component 2 is placed in the limiting plate 71. Then the limiting plate 71 is rotated through the third rotating shaft 72 until the magnetic suction plate 73 on the limiting plate 71 is magnetically connected to the magnetic suction block 74, thus limiting the magnetized component 2.

[0043] like Figures 1-4 As shown: During operation, the lighting lamp 3 allows inspectors to clearly see the fine magnetic traces formed by the magnetic powder on the surface of the connecting shaft 42. When the angle of the lighting lamp 3 needs to be adjusted, the electric push rod 52 is activated, driving the connecting piece 56 to move. The connecting piece 56, through the first rotating shaft 55, drives the connecting plate 53 to move. The connecting plate 53, in turn, drives the convex plate 43 to rotate through the slide groove 44, thus adjusting the angle of the top lighting lamp 3. The limiting ring 45 limits the connecting shaft 42 to prevent it from falling out of the slide 44, and the clamping assembly 6 on the top of the top plate 46 fixes and limits the lighting lamp 3 to prevent it from falling off the top of the top plate 46. When it is necessary to carry it, the wire 10 is hung on the extension 9 for storage. Then the magnetizing assembly 2 is placed in the limiting plate 71. Then the limiting plate 71 is rotated through the third rotating shaft 72 until the magnetic suction plate 73 on the limiting plate 71 is magnetically connected to the magnetic suction block 74, thus limiting the magnetizing assembly 2.

[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model.
