Description

Technical Field

[0001] The utility model relates to the technical field of nondestructive testing, in particular to a high-precision micro-magnetic yoke integrated machine. Background Art

[0002] By utilizing the interaction between the leakage magnetic field and magnetic powder at the defects of the workpiece, and the difference in magnetic permeability between the surface and near-surface defects of steel products (such as cracks, slag inclusions, hairlines, etc.) and the magnetic permeability of steel, the magnetic field at the discontinuity of these materials will be distorted after magnetization, forming a leakage magnetic field on the surface of the workpiece where some magnetic flux leaks, thereby attracting magnetic powder to form magnetic powder accumulation at the defects. Under appropriate lighting conditions, the defect position and shape are revealed, and the accumulation of these magnetic powders is observed and interpreted, thus achieving magnetic particle inspection. Magnetic particle inspection is one of the five conventional methods of non-destructive testing, and is also a common means of inspecting surface or near-surface defects of ferromagnetic materials. It is widely used due to its high detection sensitivity and simple and reliable process.

[0003] For example, in the prior art, the patent application with publication number CN 207351958 U uses a power supply, a cross-yoke probe, and a control module for converting the direct current in the rechargeable battery pack into a pulse signal. A handle is provided on the top of the cross-yoke probe, and a magnetizing switch for controlling the opening and closing of the magnetic detector is provided at the bottom of the handle. A power switch and a lighting conversion switch are provided at one end of the handle, and a real-time power display window and a DC power socket are provided at the other end of the handle. A movable pulley is provided at the bottom of the cross-yoke probe. The power switch is located between the power supply and the control module, and the power display window and the lighting conversion switch are both electrically connected to the control module, and the indicator light and the DC power socket are both electrically connected to the power supply. A movable pulley is provided at the bottom of the cross-yoke probe to facilitate the movement of the rechargeable cross-yoke integrated machine. An additional power switch is provided to control whether the whole machine is powered on or not, to prevent accidental touching of the magnetizing switch, which not only wastes power but also poses a risk of electric shock.

[0004] However, after the device is used, its volume is fixed and cannot be reduced, which makes it inconvenient for users to store and carry it due to its large volume.

[0005] Therefore, it is necessary to provide a high-precision micro-magnetic yoke integrated machine to solve the above technical problems. Utility Model Content

[0023] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0024] First embodiment

[0025] Please refer to Figure 1 , Figure 2 , Figure 3 ,in, Figure 1 A schematic structural diagram of a first embodiment of a high-precision micro-magnetic yoke integrated machine provided by the utility model; Figure 2 for Figure 1 The handle structure diagram shown; Figure 3 for Figure 2 A high-precision micro-magnetic yoke integrated machine, comprising: a yoke integrated machine body 1, the top and both sides of the yoke integrated machine body 1 are provided with grooves 11, both sides of the inner side of the groove 11 are fixedly mounted with slide plates 12, and the top and bottom of the slide plate 12 are fixedly mounted with first magnetic plates 13;

[0026] The handle 2 has movable grooves 21 at both ends of both sides, and second magnetic plates 22 are fixedly mounted on the top and bottom of the inner side of the movable groove 21 .

[0027] The two sides of the handle 2 are respectively attached to the two sides of the inner side of the groove 12 .

[0028] Two sides of the slide plate 12 are respectively attached to two sides of the inner side of the moving groove 21 .

[0029] The two first magnetic plates 13 are respectively disposed in the middle of the two second magnetic plates 22 .

[0030] After use, the handle 2 can be moved downward to be stored in the inner side of the groove 11.

[0031] After the second magnetic plate 22 and the first magnetic plate 13 have been used for a long time and their magnetic force has decreased, the first magnetic plate 13 and the second magnetic plate 22 can be replaced;

[0032] The yoke integrated machine body 1 is a high-precision micro yoke integrated machine.

[0033] The working principle of a high-precision micro-magnetic yoke integrated machine provided by the utility model is as follows:

[0034] When it is necessary to use the yoke integrated machine, the user can lift the handle 2 upwards, so that the first magnetic plate 13 installed on the top of the slide plate 12 and the second magnetic plate 22 installed on the top of the inner side of the moving groove 21 are separated. At this time, the user lifts the handle 2 upwards, so that the slide plate 12 slides on the inner side of the moving groove 21, and the handle 2 slides on the inner side of the groove 11, until the second magnetic plate 22 installed at the bottom of the inner side of the moving groove 21 and the first magnetic plate 13 installed at the bottom of the slide plate 12 are magnetically attracted, thereby limiting the handle 2. At this time, the user can hold the handle 2 to move the yoke integrated machine body 1 and operate the yoke integrated machine body 1;

[0035] After use, the handle 2 is pressed upward to separate the first magnetic plate 13 and the second magnetic plate 22, and then the handle 2 is stored in the inner side of the groove 11, so as to limit the storage position of the handle 2 and reduce the occupied space.

[0036] Compared with the related art, the high-precision micro-yoke integrated machine provided by the utility model has the following beneficial effects:

[0037] Through the cooperation of structures such as the yoke integrated machine body 1, the groove 11, the slide plate 12, the first magnetic plate 13, the handle 2, the movable groove 21 and the second magnetic plate 22, when in use, the first magnetic plate 13 and the second magnetic plate 22 are magnetically attracted, and the slide plate 12 slides on the inner side of the movable groove 21. In this way, when in use, the handle 2 can be taken out from the inner side of the groove 11 and limited. After use, the handle 2 can be stored on the inner side of the groove 11, thereby reducing the space occupied and making it convenient for users to carry.

[0038] Second embodiment

[0039] Please refer to Figure 4 Based on the high-precision micro-magnetic yoke integrated machine provided in the first embodiment of the present application, the second embodiment of the present application proposes another high-precision micro-magnetic yoke integrated machine. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0040] Specifically, the difference of the high-precision micro-yoke integrated machine provided in the second embodiment of the present application is that, in a high-precision micro-yoke integrated machine, both sides of the two ends of the handle 2 are provided with sliding grooves 3, and one side of the sliding groove 3 extends to the inner side surface of the movable groove 21.

[0041] Gaskets 31 are provided at both ends of the handle 2 , and locking screws 32 are provided on the inner side of the gasket 31 and the slide slot 3 .

[0042] One end of the locking screw 32 is threadedly connected to the interior of the slide plate 12 .

[0043] When in use, the locking screw 32 can slide on the inner side of the slide groove 3 , and when limiting is required, the locking screw 32 can be rotated so that the locking screw 32 presses against the gasket 31 to limit the handle 2 .

[0044] The working principle of a high-precision micro-magnetic yoke integrated machine provided by the utility model is as follows:

[0045] After long-term use, when the magnetic force of the first magnetic plate 13 and the second magnetic plate 22 is reduced, making it impossible to limit the handle 2, the user can rotate the locking screw 32 to make one end of the locking screw 32 threadedly connected inside the skateboard 12. At this time, one side of the locking nut 32 drives the gasket 31 to move, so that one side of the gasket 31 is attached to one side of the handle 2, and one side of the locking screw 32 is attached to one side of the locking screw 32, thereby limiting the handle 2 and preventing the handle 2 from moving.

[0046] Compared with the related art, the high-precision micro-yoke integrated machine provided by the utility model has the following beneficial effects:

[0047] Through the cooperation of structures such as the slide groove 3, the gasket 31 and the locking screw 32, when the magnetic force of the first magnetic plate 13 and the second magnetic plate 22 is reduced, the user can rotate the locking screw 32 so that one end of the locking screw 32 is threadedly connected to the inside of the skateboard 12, thereby playing an emergency role and avoiding the disappearance of the magnetic force of the first magnetic plate 13 and the second magnetic plate 22, resulting in the inability to use the device normally.
