Description

[0002] An electric motor (also known as a "motor") is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It is usually composed of a rotor core and a stator. The rotor core can rotate inside the stator to convert energy.
[0003] Before the rotor core is assembled with the stator, it is necessary to insert magnets on the rotor core. Conventional methods of inserting magnets mainly include equipment and manual work. Manual insertion of magnets for products with relatively small output can avoid the trouble of repeatedly debugging equipment. At present, corresponding magnet insertion tooling has been developed on the market to assist the manual insertion of magnets. However, although conventional magnet insertion tooling can relatively improve the efficiency of magnet insertion, it is very difficult to match and align the magnet slots on the magnet insertion tooling with the magnet slots on the rotor core. If the magnet slots are not matched or aligned, it is easy for the magnet slots to be misaligned or the magnets to fail to be inserted, and even the magnet surface may be scratched, greatly reducing its convenience and practicality.
[0004] It should be noted that the information disclosed in this background technology section is only intended to increase the understanding of the overall background of the utility model, and should not be regarded as an admission or suggestion in any form that the information constitutes prior art already known to a person skilled in the art.

[0031] See also Figure 1 and Figure 2 , Figure 1 A schematic structural diagram of a convenient and practical magnetic steel inserting tooling provided in one embodiment of the utility model; Figure 2 This is a schematic structural diagram of a tooling body and a rotor core provided in one embodiment of the utility model.
[0032] In order to solve the technical problem of the difficulty in matching and aligning the conventional magnetic steel tooling with the rotor core, or to achieve at least one of the above advantages or other advantages, an embodiment of the utility model provides a convenient and practical magnetic steel tooling. As shown in the figure, the convenient and practical magnetic steel tooling includes a tooling body 10, a rotor core 20 and a positioning member 30.
[0033] The tooling body 10 has a first surface and a second surface opposite to each other. A magnetic steel slot 40 is provided on the tooling body 10 for placing and inserting the magnetic steel. The magnetic steel slot 40 extends from the first surface of the tooling body 10 to the second surface of the tooling body 10, that is, the magnetic steel slot 40 runs through the tooling body 10. It can be understood that the number of the magnetic steel slots 40 can be multiple, which is specifically customized according to production requirements and is consistent with the number of magnetic steel slots on the rotor core 20.
[0034] The rotor core 20 is connected to the first surface of the tooling body 10. Through holes are provided on the tooling body 10 and the rotor core 20 for assembling the rotating shaft 50. The rotating shaft 50 can preliminarily realize the positioning of the tooling body 10 and the rotor core 20.
[0035] When the rotor core 20 and the tooling body 10 are connected, the magnetic steel slots 40 on the tooling body 10 are matched and aligned with the magnetic steel slots (not shown in the figure) on the rotor core 20. At this time, the magnets can be inserted into the magnetic steel slots on the rotor core 20 through the magnetic steel slots 40, which can improve the efficiency of manual insertion of the magnets.
[0036] The positioning member 30 is a retractable positioning member. In a specific implementation, there are at least two positioning members 30. The two positioning members 30 are arranged oppositely on the first surface of the tooling body 10. A positioning groove 60 is provided on the rotor core 20 at a position corresponding to the positioning member 30, and the positioning member 30 can extend into the positioning groove 60 and be movably connected with the positioning groove 60.
[0037] Specifically, when the tooling body 10 and the rotor core 20 are connected, the magnetic steel slots 40 and the magnetic steel slots on the rotor core may be in a state of mismatching and misalignment. At this time, the positioning member 30 and the positioning slot 60 are also in a state of mismatching, and the positioning member 30 is pressed by the rotor core 20 and shrinks in the tooling body 10. At this time, the tooling body 10 and the rotor core 20 can be rotated relative to each other. When the positioning member 30 and the positioning slot 60 are rotated to match each other, the positioning member 30 extends into the positioning slot 60 to position and limit the tooling body 10 and the rotor core 20. At this time, the magnetic steel slots 40 and the magnetic steel slots on the rotor core 20 are also in a state of matching and alignment. The magnetic steel can be smoothly inserted into the rotor core 20 through the magnetic steel slots 40, thereby improving the efficiency of manual insertion of the magnetic steel.
[0038] By providing a retractable positioning member 30, the technical difficulty of matching and aligning the magnetic steel in the conventional magnetic steel insertion tooling can be avoided. The matching and alignment of the magnetic steel slots can be quickly completed by relatively rotating the tooling body 10 and the rotor core 20, which greatly improves the practicality of the magnetic steel insertion tooling.
[0039] On the basis of the above, the first surface of the tooling body 10 also has an extension portion 70. In specific implementation, the extension portion 70 is higher than the first surface of the tooling body 10. When the tooling body 10 and the rotor core 20 are connected, the extension portion 70 is also connected to the rotor core 20, and the inner diameter of the extension portion 70 is slightly larger than the outer diameter of the rotor core 20. That is, the extension portion 70 can cover part of the rotor core 20, which is used to assist in positioning the position between the tooling body 10 and the rotor core 20, so as to avoid the position deviation that causes the positioning member 30 to fail to smoothly extend into the positioning groove 60.
[0040] In some preferred embodiments, the extension portion 70 is 3 mm higher than the first surface of the tooling body 10 , which ensures that the extension portion 70 can play an auxiliary positioning role while saving the manufacturing cost of the tooling body 10 .
[0041] Please combine Figure 1 See also Figure 3In some preferred embodiments, as shown in the figure, the positioning member 30 includes a positioning pin 31, an elastic member 32 and an ejector pin 33. The positioning pin 31 is embedded in the first surface of the tooling body 10. An end of the positioning pin 31 away from the tooling body 10 is provided with an axial hole 311, and the elastic member 32 and the ejector pin 33 are arranged in the axial hole 311. One end of the elastic member 32 abuts against the axial hole 311, and the other end of the elastic member 32 abuts against the ejector pin 33. The ejector pin 33 is slidably connected to the positioning pin 31, and the ejector pin 33 protrudes from the positioning pin 31.
[0042] In a specific implementation, a groove is formed on the first surface of the tooling body 10, and the positioning pin 31 is embedded in the groove, thereby fixing the positioning pin 31 on the tooling body 10. An axial hole 311 is formed at one end of the positioning pin away from the tooling body 10. It can be understood that the axial hole 311 is open at one end, and the end located in the tooling body 10 is not open. The elastic member 32 and the ejector pin 33 are respectively located in the axial hole 311.
[0043] One end of the elastic member 32 abuts against the unopened end of the shaft hole 311, and the other end of the elastic member 32 abuts against the ejector pin 33, so that the ejector pin 33 can slide in the positioning pin 31 to achieve the telescopic function. When the ejector pin 33 is not aligned with the positioning groove 60, the ejector pin 33 is compressed by the rotor core 20, and then the elastic member 32 is compressed, so that the ejector pin 33 shrinks in the positioning pin 31. When the ejector pin 33 and the positioning groove 60 are aligned, under the action of the elastic member 32, the ejector pin 33 extends out of the positioning pin 31 and extends into the positioning groove 60, positioning and limiting the tooling body 10 and the rotor core 20, greatly reducing the difficulty of matching and aligning the magnetic steel tooling and the rotor core 20, which is convenient and quick.
[0044] On the basis of the above, a ball 80 can be embedded in one end of the ejector pin 33 away from the positioning pin 31. The ball 80 is connected to the ejector pin 33 in a rolling manner. When the ejector pin 33 is not aligned with the positioning groove 60, the tooling body 10 and the rotor core 20 need to be relatively rotated. At this time, the ball 80 is connected to the ejector pin 33 and the rotor core 20 in a rolling manner, which can reduce the friction between the ejector pin 33 and the rotor core 20, improve the smoothness of rotation, and also reduce the impact of the rotation friction on the ejector pin 33, thereby improving the service life of the positioning member 30.
[0045] Please combine Figure 2 See also Figure 4 , Figure 5 In some preferred embodiments, as shown in the figure, a cutting portion 90 is provided at the contact position between the first surface of the tooling body 10 and the positioning pin 31. Specifically, the cutting portion 90 is rounded or chamfered. By designing the cutting portion 90 with a rounded or chamfered corner, the contact area between the first surface of the tooling body 10 and the positioning pin 31 can be increased, the impact force caused by the friction force when the tooling body 10 or the rotor core 20 is rotated and aligned can be reduced, and the damage of the cutting portion 90 can be avoided, thereby increasing the service life of the positioning member 30.
[0046] In some preferred embodiments, the depth H of the positioning groove 60 is greater than the length h of the ejector pin 33. That is, when the ejector pin 33 is inserted into the positioning groove 60, the ball 80 does not contact the bottom of the positioning groove 60, which can avoid the impact on the ball 80 during contact, thereby reducing the rolling performance of the ball 80.
[0047] In some preferred embodiments, the tooling body is made of phenolic plastic, which has good mechanical strength, insulation and magnetic isolation effects. Of course, in some other embodiments, other materials with good mechanical strength, insulation and magnetic isolation properties can also be used for support, and this case is not limited to this.
[0048] In some preferred embodiments, a buffer (not shown in the figure) is provided on the first surface of the tooling body to avoid hard collision when the surface tooling body 10 and the rotor core 20 are connected to each other.
[0049] To sum up, compared with the prior art, the convenient and practical magnetic steel insertion tooling provided by the utility model has two retractable positioning components arranged on the tooling body. When the tooling body is connected to the rotor core, only the tooling body or the rotor core needs to be relatively rotated to achieve the matching and alignment of the tooling body and the rotor core, thereby avoiding the cumbersome matching and alignment methods of conventional magnetic steel insertion tooling, greatly improving the convenience and practicality of the magnetic steel insertion tooling, and improving production efficiency.
[0050] Although the term "tooling body" and "tooling body" are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
[0051] In addition, those skilled in the art should understand that, although there are many problems in the prior art, each embodiment or technical solution of the utility model can be improved in only one or several aspects, without having to solve all the technical problems listed in the prior art or background technology at the same time. Those skilled in the art should understand that the content not mentioned in a claim should not be used as a limitation on the claim.
[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
