Description

Technical Field

[0001] The utility model relates to the technical field of magnetic materials, in particular to a magnet magnetizing device and a magnetic assembly for a helicopter engine sensor. Background Art

[0002] Certain components of helicopter engines require magnetic assemblies to achieve specific functions, such as motor magnets and sensor magnetic shielding. To improve the stability and anti-interference capabilities of these assemblies, and to accommodate actual installation conditions, the assemblies must be tilted at a specific angle during production to achieve specific performance. However, existing magnetization equipment can only magnetize horizontal or vertical assemblies and is unable to magnetize magnetic materials at specific angles. Utility Model Content

[0003] To address at least one aspect of the above-mentioned problems, the present invention provides a magnet magnetizing device for a helicopter engine sensor, comprising a magnetizing base block and a cover plate. The magnetizing base block is provided with an inclined placement groove, which is suitable for accommodating magnetic material in an inclined state after being placed therein. The magnetizing base block is suitable for being placed in a magnetizing device. The cover plate blocks the notch of the inclined placement groove, and the cover plate is detachably connected to the magnetizing base block.

[0004] Optionally, the oblique placement slot passes through the magnetized base block, and two cover plates are provided, and the two cover plates respectively cover the slot openings at both ends of the oblique placement slot.

[0005] Optionally, a plurality of the inclined placement slots are arranged at intervals, and the cover plate blocks the slot openings of the plurality of the inclined placement slots.

[0006] Optionally, a knife entry groove is further provided on one side of the magnetized base block where the inclined placement groove is provided, and the knife entry groove is communicated with the inclined placement groove.

[0007] Optionally, the angle between the outer wall surface of the inclined placement groove and the vertical surface of the magnetized base block (1) is sixty degrees.

[0008] Optionally, the cover plate is provided with connecting bolts, and the cover plate is connected to the magnetized base via the connecting bolts.

[0009] Compared with the prior art, the beneficial technical effects of the present invention are as follows: the magnetic material can be in an inclined state after being placed in the inclined placement slot, and the magnetization base block can be placed in the magnetization equipment to achieve magnetization of the magnetic material at a specific inclined angle; the cover plate blocks the slot opening of the inclined placement slot, making it difficult for the magnetic material to escape from the slot opening of the inclined placement slot during the magnetization process, thereby improving the stability during magnetization; the setting of multiple inclined placement slots can magnetize multiple magnetic materials at one time, thereby improving production efficiency.

[0010] In addition, the utility model provides a magnetic assembly, which is manufactured by magnetizing the magnet magnetizing device of the helicopter engine sensor as described above.

[0011] Optionally, the magnetic assembly includes a plurality of single magnetic steels (3), and the magnet magnetizing device of the helicopter engine sensor includes an inclined placement slot (11), wherein a plurality of the single magnetic steels (3) are inserted into one of the inclined placement slots (11).

[0012] Optionally, a plurality of the single magnetic steels are bonded and connected to each other.

[0013] Optionally, a directional groove is provided on one side of the single magnetic steel.

[0014] Compared with the prior art, the beneficial technical effects of the present invention are:

[0015] 1. The magnetic properties of the magnetic assembly are relatively stable after tilted magnetization. After being installed on the helicopter engine, its working accuracy and reliability can be improved. Bonding multiple single magnets into a group has strong anti-interference ability, which reduces the interference of the external magnetic field. The setting of the directional groove facilitates the bonding of magnets and the confirmation of the magnetization direction, so that the magnetization direction of each single magnet is consistent. When the magnetic assembly needs to be maintained or replaced, the entire magnetic assembly is directly replaced, and the replaced one is reintegrated and bonded, which not only avoids the waste of recycling resources, but also greatly facilitates maintenance and repair.

[0016] 2. The single magnet can be bonded together to enhance the magnetic force and make the magnetic field more stable. In the case of damage to the magnet, if a whole large magnet is slightly damaged, it will greatly affect the stability of the entire magnetic field and cause the magnetic field to collapse, which is extremely detrimental to the use on the equipment. Instead, it is changed to multiple single magnets bonded together, which not only strengthens the magnetic field size, but also improves the stability. Because in the case of damage, the damage to the individual bonded body has a much smaller impact on the overall stability than the impact of the overall damage, which can provide the greatest protection for use in extreme environments;

[0017] 3. For 60° magnetization, it breaks the traditional horizontal magnetization. After the magnetic assembly is installed on the helicopter engine, it can create a more novel structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] In the description of the present invention, it should be understood that the terms "upper" and "lower" and the like indicate positions or location relationships based on the positions or location relationships during normal use of the product.

[0024] The following is combined with Figure 1-3 This application is described in further detail.

[0025] In the first aspect, the embodiment of the present invention provides a magnet magnetizing device for a helicopter engine sensor, referring to Figure 1 The magnetizing device for the helicopter engine sensor includes a magnetizing base block 1 and a cover plate 2. An inclined placement slot 11 is provided on the outer wall of one side of the magnetizing base block 1 in the horizontal direction. The inclined placement slot 11 is inclined relative to the horizontal plane. After the magnetic material is placed in the inclined state, the magnetizing base block 1 is placed in the magnetizing device, and the magnetic material can be magnetized at a specific tilt angle. The cover plate 2 can be detachably mounted on the magnetizing base block 1 to block the opening of the inclined placement slot 11, so that the magnetic material is not easily ejected from the slot of the inclined placement slot 11 due to changes in the magnetic field during the magnetization process.

[0026] Reference Figure 1 , there are multiple inclined placement slots 11, and the multiple inclined placement slots 11 are arranged at intervals, and the inclination directions and angles of the multiple inclined placement slots 11 are the same. The above arrangement can magnetize multiple magnetic materials in multiple inclined placement slots 11 at one time during magnetization, thereby improving production efficiency. In addition, the interval arrangement of multiple inclined placement slots 11 also makes it difficult for the magnetic materials in two adjacent inclined placement slots 11 to affect each other's magnetic field due to the generation of magnetic fields between each other during the magnetization process. In this embodiment, four inclined placement slots 11 are preferably provided, and the connecting line between the four inclined placement slots 11 is a rectangle. The structure of one inclined placement slot 11 is described below as an example.

[0027] Reference Figure 1The inclined placement groove 11 passes through the magnetized base block 1 itself along the opening direction, so that the depth of the inclined placement groove 11 is deeper, and a larger number of magnetic materials can be placed, further improving production efficiency. In this embodiment, the inclined placement groove 11 is preferably an inclined rectangular groove, and a tool entry groove is provided at a right angle of the inclined placement groove 11, and the tool entry groove is connected to the inclined placement groove 11, so that it is convenient for the turning tool to perform turning when processing the inclined placement groove 11. The other three right angles of the inclined placement groove 11 are provided with tool withdrawal grooves. The setting of the tool withdrawal groove can improve the processing accuracy of the inclined placement groove 11, thereby improving the uniformity of the magnetic field when magnetizing the magnetic material.

[0028] Reference Figure 1 In this embodiment, the angle between the inclined placement slot 11 and the vertical plane is preferably 60 degrees. This configuration enables the magnetized magnetic material to have a specific magnetic field, and the magnetic field stability is high after the magnetic material is installed in the corresponding equipment. In other embodiments, the angle between the inclined placement slot 11 and the vertical plane can be 30 degrees, 40 degrees, 50 degrees, 70 degrees, 80 degrees, etc., and can be selected according to the actual magnetic field requirements.

[0029] Because the inclined placement slot 11 extends through the magnetized base block 1, two cover plates 2 are provided. These two cover plates 2 are located on either side of the magnetized base block 1 to cover the openings at both ends of the inclined placement slot 11. The two cover plates 2 have the same structure and mounting arrangement, and the following description will use one cover plate 2 as an example.

[0030] Reference Figure 1 , multiple inclined placement slots 11 are all located within the range of the cover plate 2, that is, the cover plate 2 can block the notches of the multiple inclined placement slots 11. A plurality of threaded holes are spaced apart on one side of the magnetizing base block 1 close to the cover plate 2, and the cover plate 2 is provided with bolt holes with the same number as the threaded holes. The multiple bolt holes correspond one to one with the multiple threaded holes, and connecting bolts (not shown in the figure) are inserted into the bolt holes. The connecting bolts are threadedly installed in the threaded holes, thereby connecting the cover plate 2 to the magnetizing base. Considering the existence of the magnetic field, the magnetizing base, the cover plate 2 and the connecting bolts are all made of plastic. In another embodiment, one side of the cover plate 2 is hingedly connected to the magnetizing base by a hinge made of plastic material, and the other side is connected to the magnetizing base by a connecting bolt.

[0031] In another embodiment, the inclined placement groove 11 may not penetrate the magnetized base block 1 , and correspondingly, only one cover plate 2 is provided.

[0032] The implementation principle of the magnet magnetizing device for a helicopter engine sensor in an embodiment of the present application is as follows: when magnetizing a magnetic material that needs to be tilted at a specific angle, the magnetic material can be placed in an inclined placement slot 11. After being placed in the inclined placement slot 11, the magnetic material will be inclined at a specific angle. Then, the cover plate 2 is installed on the magnetizing base block 1 using connecting bolts to block the notch of the inclined placement slot 11. Finally, the magnetizing base block 1 is placed horizontally in the magnetizing device for magnetization. During the magnetization process, since the cover plate 2 blocks the notch of the inclined placement slot 11, the magnetic material in the inclined placement slot 11 is not easily ejected from the inclined placement slot 11 due to changes in the magnetic field and the action of the magnetic force.

[0033] In a second aspect, another embodiment of the present invention provides a magnetic assembly, which is processed by the magnet magnetizing device of the above-mentioned helicopter engine sensor. The magnetic assembly can be used on the helicopter engine sensor and can also be used on other devices.

[0034] Reference Figure 2 The magnetic assembly includes multiple single magnetic steels 3. Before magnetization, the multiple single magnetic steels 3 are bonded together by glue to form a whole. This arrangement enables the multiple single magnetic steels 3 to maintain a stable connection during the magnetization process and is not prone to unstable connection caused by the generation of a magnetic field.

[0035] Reference Figure 2 and Figure 3 Each single magnetic steel 3 is provided with an orientation groove 31 on the same side. After multiple single magnetic steels 3 are bonded together, the orientation grooves 31 on the multiple single magnetic steels 3 face the same direction, which facilitates the bonding of the magnetic steels and the confirmation of the magnetization direction, so that the magnetization direction of each single magnetic steel 3 is consistent.

[0036] Combine Figure 1 Reference Figure 2 and Figure 3 During magnetization, multiple bonded individual magnetic steels 3 are placed as a group of magnets into the inclined placement slots 11 of the magnetization base block 1. The magnetic field of the multiple bonded individual magnetic steels 3 is changed after magnetization, making the generated magnetic field more stable.

[0037] The working principle of a magnetic assembly in an embodiment of the present application is as follows: multiple individual magnets 3 are bonded together and magnetized, resulting in a modified magnetic field. This allows the device equipped with the magnetic assembly to have strong anti-interference capabilities and minimize interference from external magnetic fields. When installed on a helicopter engine, this improves its operating accuracy and reliability. When maintenance or replacement of the magnetic assembly is required, the entire assembly is simply replaced and then reassembled and bonded. This eliminates wasteful recycling and greatly facilitates maintenance and repair.

[0038] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of the present utility model.
