Description

Technical Field

[0001] This application relates to the field of magnet assembly technology, and in particular to a fault-prevention tooling for installing magnets. Background Technology

[0002] As permanent magnet motor technology matures, its applications are expanding, covering numerous industries. The motor rotor, a key component of a permanent magnet motor, requires the insertion of magnets inside. However, precisely installing these magnets into the rotor's core has become a significant challenge for many permanent magnet motor manufacturers.

[0003] Currently, the assembly of magnets mainly relies on manual operation. Due to the attractive force between the magnet and the iron core, manual installation is physically demanding. Furthermore, the lack of effective guiding devices during assembly easily leads to friction between the magnet surface and the iron core slots. In addition, magnets have N and S poles, requiring strict differentiation of the positive and negative directions during assembly. Incorrect assembly necessitates rework, which not only increases the workload of operators but also reduces production efficiency. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a fault-prevention tooling for installing magnets, so as to solve the problems of assembly difficulties and rework due to incorrect installation when manually installing magnets.

[0005] According to this utility model, a fault-prevention fixture for installing magnets is provided, wherein the fault-prevention fixture for installing magnets includes: a fixture body having multiple magnet slots for inserting magnets, multiple slides being provided within the fixture body, the multiple slides being respectively connected to the multiple magnet slots; a magnet being movably disposed within the slides; and a connecting part, the fixture body being connected to the iron core through the connecting part; when the fixture body is installed on the iron core, the multiple magnet slots are connected one-to-one with the multiple magnet grooves of the iron core.

[0006] Preferably, the magnet slot extends vertically through the tooling body.

[0007] Preferably, the slide is arranged horizontally, with its first end connected to the outside of the tooling body and its second end connected to the magnet slot.

[0008] Preferably, the slide is a cylindrical cavity, and the magnet is cylindrical in shape.

[0009] Preferably, the axial direction of the slide is perpendicular to the outer surface of the tooling body.

[0010] Preferably, the second end of the slide is provided with an internal thread, and the anti-misalignment tooling for installing the magnet also includes a plug, which is provided with an external thread and can be threadedly connected to the second end of the slide.

[0011] Preferably, the slot of the magnet slot has a chamfer.

[0012] Preferably, the connecting part includes a first positioning hole that penetrates the tooling body in a vertical direction, a second positioning hole that is aligned with the first positioning hole at the top of the iron core, and a positioning pin that passes through the first positioning hole, the end of the positioning pin being able to be inserted into the second positioning hole.

[0013] Preferably, there are multiple first positioning holes, and the multiple first positioning holes are arranged at intervals along the length direction of the tooling body.

[0014] Preferably, the tooling body is provided with symbols and / or engravings to indicate the corresponding magnetic pole inserted into the magnet slot.

[0015] This utility model discloses a fault-prevention fixture for installing magnets. The fixture body has multiple magnet slots for inserting magnets, and multiple slides are provided within the fixture body, each connected to one of the magnet slots. Magnets are movably disposed within the slides, so that when the magnetic pole of the inserted magnet differs from the magnetic pole of the magnet, the magnet moves from the slide to the magnet slot, preventing further insertion and avoiding rework. The fixture body is connected to an iron core via a connecting part, and when the fixture body is installed on the iron core, the multiple magnet slots correspond one-to-one with the multiple magnet grooves in the iron core. Therefore, the fixture body can separate the magnets from the iron core, and the magnet slots can act as guides, greatly reducing the difficulty of magnet installation. This effectively solves the problems of assembly difficulties and easy rework due to incorrect installation during manual magnet installation.

However, various changes, modifications, and equivalents of the methods, apparatus, and / or systems described herein will be apparent after understanding the disclosure of this application. For example, the order of operations described herein is merely illustrative and is not limited to the order set forth herein; changes that will be apparent after understanding the disclosure of this application are possible, except for operations that must occur in a specific order. Furthermore, for clarity and brevity, descriptions of features known in the art may be omitted.

[0023] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many feasible ways of implementing the methods, apparatus, and / or systems described herein that will be apparent upon understanding the disclosure of this application.

[0024] Throughout the specification, when an element (such as a layer, region, or substrate) is described as being "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, it may be directly "on" another element, "connected to" another element, "bonded to" another element, "on" another element, or "covering" another element, or there may be one or more other elements in between. In contrast, when an element is described as being "directly on" another element, "directly connected to" another element, "directly bonded to" another element, "directly on" another element, or "directly covering" another element, there may be no other elements in between.

[0025] As used herein, the term “and / or” includes any one of the relevant items listed and any combination of any two or more items.

[0026] Although terms such as “first,” “second,” and “third” may be used herein to describe individual components, assemblies, regions, layers, or parts, these components, assemblies, regions, layers, or parts are not limited by these terms. Rather, these terms are used only to distinguish one component, assembly, region, layer, or part from another. Therefore, without departing from the teachings of the examples described herein, the first component, assembly, region, layer, or part referred to as the second component, assembly, region, layer, or part may also be referred to as the second component, assembly, region, layer, or part.

[0027] For ease of description, spatial relation terms such as “above,” “upper,” “below,” and “lower” are used herein to describe the relationship between one element and another, as shown in the accompanying drawings. Such spatial relation terms are intended to include not only the orientation depicted in the drawings but also different orientations of the device during use or operation.

[0031] This utility model provides a fault-prevention tooling for assembling magnets, such as... Figures 1 to 3 As shown, the error-proof fixture for mounting magnets includes a fixture body 1, a magnet 2, and a connecting part.

[0032] In the following description, reference will be made to Figures 1 to 3 The diagram illustrates the specific structure of the aforementioned components of the error-proof fixture used for installing magnets, as well as the connection relationships between these components.

[0033] like Figures 1 to 3 As shown, in this embodiment, the fixture body 1 may have multiple magnet slots 10 for inserting magnets. Simultaneously, multiple slide rails 11 may be provided within the fixture body 1. These slide rails 11 are respectively connected to the multiple magnet slots 10. The magnet 2 is movably disposed within the slide rails 11. This arrangement ensures that during the insertion of the magnet into the magnet slot 10, if the magnetic poles of the magnet and the magnet 2 are different, the magnet 2 will move from the slide rail 11 to the magnet slot 10 under the influence of magnetic force, thus preventing further insertion and avoiding rework after installation. The fixture body 1 can be connected to the iron core via a connecting part, and when the fixture body 1 is installed on the iron core, the multiple magnet slots 10 can be connected one-to-one with the multiple magnet slots of the iron core. Therefore, the fixture body 1 can separate the magnet from the iron core, and the magnet slots 10 can act as guides, greatly reducing the difficulty of magnet installation.

[0034] Preferred, such as Figure 1 and Figure 2 As shown, in this embodiment, the tooling body 1 can be a columnar structure with a polygonal cross-section. The tooling body 1 can include a horizontally arranged top surface and bottom surface to ensure that the bottom surface of the tooling body 1 can fit against the upper surface of the iron core. The magnet slot 10 can penetrate the tooling body 1 vertically, and the top and bottom ends of the magnet slot 10 are respectively connected to the top and bottom surfaces of the tooling body 1. This allows the bottom opening of the magnet slot 10 to align with the slot opening of the magnet groove in the iron core when the tooling body 1 is installed on the iron core, facilitating magnet insertion. The magnet slot 10 of the tooling body 1 can also serve as a guide.

[0035] Furthermore, preferably, such as Figure 1 and Figure 2 As shown, in this embodiment, a chamfer can be provided at the opening of the magnet slot 10. This serves as a guide when the operator inserts the magnet into the magnet slot 10, thereby reducing scratching between the magnet and the magnet slot 10 and preventing magnetic powder from falling off and affecting cleanliness.

[0036] Preferred, such as Figure 1 and Figure 2As shown, in this embodiment, there are multiple slides 11. The slides 11 can be arranged horizontally, such that the extension direction of the slides 11 is perpendicular to the insertion direction of the magnet, thereby enabling the magnet 2 in the slides 11 to move quickly into the magnet slot 10. Preferably, the first end of the slide 11 can be connected to the outside of the tooling body 1 (i.e., the port of the first end of the slide 11 is located on the outer surface of the tooling body 1), and the second end of the slide 11 can be connected to the magnet slot 10.

[0037] Furthermore, preferably, such as Figure 1 and Figure 2 As shown, in this embodiment, the slide 11 can be a cylindrical cavity, and correspondingly, the magnet 2 can also be cylindrical. This configuration allows the magnet 2 to move smoothly along the axial direction of the slide 11. However, it is not limited to this; the slide 11 can also be formed into other cylindrical cavities, as long as the N pole and S pole of the magnet 2 do not reverse within the slide 11.

[0038] Further optimized, such as Figure 1 and Figure 2 As shown, in this embodiment, the axis of the slide rail 11 can be perpendicular to the outer surface of the tooling body 1. Since the tooling body 1 is a polyhedron, in order to facilitate the installation of the magnet 2 on each slide rail 11, the slide rail 11 can be correspondingly perpendicular to the outer surface of the tooling body 1 to which it is located.

[0039] In addition, preferred, such as Figure 2 As shown, in this embodiment, an internal thread may be provided at the second end of the slide rail 11. The error-proof fixture for installing the magnet may also include a plug 6. The plug 6 may be a cylindrical part, and an external thread may be provided on the plug 6 so that the plug 6 can be threadedly connected to the second end of the slide rail 11 to prevent the magnet 2 from coming out of the slide rail 11.

[0040] Preferred, such as Figures 1 to 3 As shown, in this embodiment, the connecting part may include a first positioning hole 3 and a positioning pin 4. The first positioning hole 3 can penetrate the tooling body 1 vertically, that is, the first positioning hole 3 connects the top and bottom surfaces of the tooling body 1. A second positioning hole can be provided at the top of the iron core, and the second positioning hole can be aligned with the first positioning hole 3. The positioning pin 4 can pass through the first positioning hole 3, and the end of the positioning pin 4 can be inserted into the second positioning hole, thereby fixing the tooling body 1 to the top of the iron core.

[0041] Furthermore, preferably, such as Figures 1 to 3As shown, in this embodiment, there can be multiple first positioning holes 3, and correspondingly, there can also be multiple positioning pins 4. The multiple first positioning holes 3 can be spaced apart along the length of the tooling body 1, and the positions of the multiple second positioning holes correspond one-to-one with the positions of the multiple first positioning holes 3.

[0042] In addition, preferred, such as Figure 1 As shown, in this embodiment, the tooling body 1 may also be provided with symbols and / or engravings (such as...). Figure 1 Arrow 5 (as shown) is used to indicate the corresponding magnetic pole inserted into the magnet slot 10. Specifically, arrow 5 can be placed near the magnet slot 10, and the N pole or S pole can be marked on arrow 5 to facilitate operator confirmation and avoid inserting the wrong magnetic pole.

[0043] During use, first insert the positioning pin 4 into the fixture body 1 and the iron core, aligning the magnet slot of the iron core with the magnet slot 10 of the fixture body. Then, place the magnet into the magnet slot 10 of the fixture body. If the magnetic poles of the magnet are opposite to the preset insertion magnetic poles, the magnet 2 will move into the magnet slot 10 under the action of magnetic force, preventing further insertion. If the magnetic poles of the magnet are the same as the preset insertion magnetic poles, the magnet can be smoothly inserted into the magnet slot 10. After inserting the magnet into the magnet slot 10, the magnet can move into the magnet slot of the iron core under the action of magnetic force, thus completing the installation of the magnet.

[0044] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto.
