Description

Technical Field

[0001] This utility model relates to the field of magnet processing equipment technology, and in particular to an auxiliary tool used when magnetizing by a magnetizing coil. Background Technology

[0002] In the production process of permanent magnets, the magnetization process is crucial. Currently, most manufacturers use manual operation, placing a jig containing a magnet into a magnetization coil for magnetization. However, each time magnetization is performed, the position of the jig in the magnetization coil may deviate, resulting in inaccurate jig positioning. This inaccurate positioning will cause the magnetization magnetic field to deviate from the product orientation direction, leading to problems such as incomplete magnetization, low magnetic moment, and inconsistent magnetization. These problems are particularly prominent in the magnetization process of irregularly shaped magnets.

[0003] Therefore, how to improve the accuracy of magnetization through a magnetization coil using a simple structure has become an urgent problem to be solved. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary tool for magnetizing using a magnetizing coil. The technical problem to be solved is how to improve the accuracy of magnetizing using a magnetizing coil through a simple structure.

[0005] To achieve the above objectives, the solution of this utility model is: an auxiliary tool used when magnetizing through a magnetizing coil, which is used on the magnetizing coil and includes a fixed base, a guide rail and a sliding assembly;

[0006] The magnetizing coil has a magnetizing channel in the center. The magnetizing coil is used to magnetize the magnet in the magnetizing channel. One end of the magnetizing channel is open to form a magnetizing inlet.

[0007] The mounting base is fixedly installed outside the magnetization inlet;

[0008] The guide rail is fixedly mounted on the fixed base, with one end extending outside the magnetization channel and the other end extending from the magnetization inlet into the magnetization channel;

[0009] The sliding assembly is slidably mounted along the guide rail so that it can slide into or out of the magnetization channel along the extension path of the guide rail. The sliding assembly can be used to fix the magnet in a fixed posture so as to support the magnet entering or leaving the magnetization channel.

[0010] Furthermore, the sliding assembly includes a sliding seat and a fixture. The sliding seat is slidably mounted on the guide rail and has a first fixing part. The fixture is fixed to or removed from the first fixing part and is used to fix the magnet.

[0011] Furthermore, the first fixing part is a fixture groove formed in the sliding seat, and the fixture groove matches the cross-sectional shape of the fixture so that the fixture can be embedded and fixed.

[0012] Furthermore, after the fixture is embedded in the fixture groove, a plurality of magnet grooves are formed on one side surface exposed outside the fixture groove, and each magnet groove is used for embedding and fixing a magnet.

[0013] Furthermore, after the fixture enters the magnetization channel, the side of the fixture with the magnet slot is parallel to the magnetization magnetic field of the magnetization coil.

[0014] Furthermore, the fixed base, guide rail, and sliding assembly are all made of non-ferromagnetic materials.

[0015] Furthermore, the fixed base, guide rail, and sliding assembly are all made of plastic.

[0016] Furthermore, a gaussmeter is mounted on the sliding component.

[0017] After adopting the above solution, the beneficial effects of this utility model are as follows:

[0018] (1) The fixed base is fixed outside the magnetization inlet, and the guide rail is fixed on the fixed base. One end extends outside the magnetization channel, and the other end extends from the magnetization inlet into the magnetization channel. The sliding component is slidably set along the guide rail so that it can slide into or out of the magnetization channel according to the extension path of the guide rail. The sliding component can be fixed with a magnet to carry the magnet into or out of the magnetization channel. Since the sliding component moves along the extension path of the guide rail, and the magnet is fixed on the sliding component, the magnet can be in the same posture each time it enters the magnetization channel, ensuring the consistency of the magnetization direction, and thus ensuring the accuracy when magnetizing through the magnetization coil.

[0019] (2) During operation, you only need to slide the sliding component out of the magnetization channel, fix the magnet on the sliding component, and then slide the sliding component back into the magnetization channel to complete the entire magnetization process. The operation is very simple. Attached Figure Description

[0024] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Unless otherwise expressly defined, the use of directional terms such as "center," "lateral," "longitudinal," "horizontal," "vertical," "top," "bottom," "inner," "outer," "upper," "lower," "front," "rear," "left," "right," "clockwise," and "counterclockwise" in the claims, description, and accompanying drawings of this invention is merely for the convenience of describing the invention and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the specific scope of protection of this invention.

[0026] An auxiliary tool used during magnetization via a magnetization coil, such as Figure 1-3 As shown, it is used on magnetizing coil 1. Magnetizing coil 1 is a conventional design in the art. It can be any existing magnetizing coil that generates a magnetic field under electromagnetic action to magnetize the magnet placed inside. The auxiliary tools used when magnetizing through the magnetizing coil include a fixed base 2, a guide rail 3 and a sliding component 4. In order not to interfere with the magnetic field generated by the magnetizing coil 1 and avoid affecting the magnetizing effect, it is preferable that the fixed base 2, the guide rail 3 and the sliding component 4 are all made of non-ferromagnetic materials. Specifically, in this embodiment, they are all made of plastic material.

[0027] The magnetizing coil 1 is annular with a magnetizing channel 5 in the center. The magnetizing coil 1 is used to magnetize the magnet 6 inside the magnetizing channel 5. One end of the magnetizing channel 5 is open, forming a magnetizing inlet 7. The fixing base 2 is fixedly installed outside the magnetizing inlet 7. The fixing method is not limited, as long as it can maintain a relatively fixed position with the magnetizing coil 1. It can be a technical solution to fix the magnetizing coil 1 and the fixing base 2 on a bracket at the same time, or it can be as in this embodiment, the fixing base 2 is directly fixed to the magnetizing coil 1. The guide rail 3 is fixedly installed on the fixing base 2. One end of the guide rail 3 extends outside the magnetizing channel 5, and the other end extends from the magnetizing inlet 7 into the magnetizing channel 5. Specifically, in this embodiment, the guide rail 3 extends in a straight line and is parallel to the extension direction of the magnetizing channel 5. The sliding component 4 slides along the guide rail 3. The sliding component 4 is positioned so that it can slide into or out of the magnetization channel 5 along the extension path of the guide rail 3. The process of sliding into or out of the magnetization channel 5 can be done manually, or a linear drive mechanism such as a cylinder or linear motor can be set to drive the sliding component 4 to slide (conventional setting, not shown in the attached figure). The magnet 6 can be fixed on the sliding component 4 in a predetermined posture to carry the magnet 6 into or out of the magnetization channel 5. Therefore, during operation, it is only necessary to slide the sliding component 4 out of the magnetization channel 5, fix the magnet 6 on the sliding component 4, and then slide the sliding component 4 into the magnetization channel 5 to complete the entire magnetization process. Moreover, each time the sliding component 4 carries the magnet 6 into the magnetization channel 5, it can ensure that the magnet 6 on it is accurately in the predetermined posture. Thus, the structure is simple, the operation is convenient, and more accurate magnetization is achieved at the same time.

[0028] In a preferred embodiment, to facilitate the placement and removal of magnets, the sliding assembly 4 includes a sliding seat 8 and a fixture 9. The sliding seat 8 is slidably mounted on the guide rail 3 and has a first fixing part. The fixture 9 is fixed or removed from the first fixing part and is used to fix the magnet 6. Specifically, in this embodiment, the first fixing part is a fixture groove 10 formed in the sliding seat 8. The fixture groove 10 matches the cross-sectional shape of the fixture 9 so that the fixture 9 can be embedded and fixed. After the fixture 9 is embedded in the fixture groove 10, a plurality of magnet grooves 11 are formed on one side surface exposed outside the fixture groove 10. Each magnet groove 11 is used to embed and fix one magnet 6. Specifically, in this embodiment, the cross-section of the pre-magnetized magnet is triangular, so the cross-section of each magnet groove 11 is also triangular, thereby ensuring the posture of the magnet on the fixture through the magnet grooves 11.

[0029] Specifically, in this embodiment, in order to ensure the consistency of magnetization of each magnet 6, the magnet slots 11 are arranged in a linear array. After the fixture 9 enters the magnetization channel 5, the side of the fixture 9 with the magnet slots 11 is parallel to the magnetization magnetic field of the magnetization coil 1, thereby ensuring that the magnetization effect of each magnet 6 is consistent.

[0030] In a preferred embodiment, in order to ensure the consistency of the magnetic field during each magnetization, a gaussmeter 12 is installed on the sliding assembly 4 to measure the magnetic field strength during each magnetization. More specifically, the gaussmeter 12 is installed on the sliding seat 8, facing away from the side where the fixture groove 10 is provided.

[0031] The above description is only a preferred embodiment of this utility model and is not intended to limit the design of this case. All equivalent changes made based on the key design of this case shall fall within the protection scope of this case.
