Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing technology, and more specifically, to an assembly fixture and a manufacturing apparatus for a permanent magnet synchronous motor. Background Technology

[0002] A permanent magnet synchronous motor generates electromagnetic torque to drive the rotor to rotate by the interaction between the rotating magnetic field generated by the stator windings and the magnetic field of the rotor permanent magnets. The rotor typically contains magnets, while the stator consists of silicon steel sheets and coils. Due to the strong magnetism of the magnets and the high permeability of the silicon steel sheets, a huge magnetic attraction force is generated during the assembly of the rotor and stator. This magnetic attraction force not only increases the difficulty of assembly but also easily leads to violent collisions between the rotor and stator, thereby damaging motor components. In addition, the strong magnetic attraction force may also cause installers to be pinched and injured during the assembly process. Utility Model Content

[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide an assembly fixture that can reduce the influence of magnetic attraction on the assembly of the rotor and stator.

[0004] This application also provides a manufacturing apparatus for a permanent magnet synchronous motor.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, this application provides an assembly fixture for assembling the stator and rotor of a permanent magnet synchronous motor. The assembly fixture has a first direction and includes: a base; a first fixing component connected to the base; a guide component connected to the base and extending along the first direction, wherein the guide component is disposed on one side of the first fixing component along the first direction; and a second fixing component connected to the guide component and spaced apart from the first fixing component along the first direction, wherein the second fixing component slides relative to the guide component along the first direction. The first fixing component is used to fix the stator and to make the central axis of the stator parallel to the first direction, and the second fixing component is used to fix the rotor and to make the central axis of the rotor coincide with the central axis of the stator.

[0007] In an optional embodiment, the assembly fixture further has a second direction that intersects with the first direction. The first fixing component includes a first fixing member and a first connecting member. The first connecting member is connected to the base. The first fixing member is rotatably connected to the first connecting member and can rotate relative to the first connecting member about the second direction to a first position or a second position. The first fixing member is used to fix the stator.

[0008] Wherein, when the first fixing member rotates relative to the first connecting member about the second direction to the first position, the first fixing member is used to make the central axis of the stator parallel to the first direction, and the first fixing member rotates from the first position about the second direction toward the direction away from the second fixing component to the second position.

[0009] In an optional embodiment, the first fixing component further includes a fastener, which is connected to the first fixing component and the first connecting component when the first fixing component is rotated relative to the first connecting component about the second direction to the first position.

[0010] In an optional embodiment, the guide assembly includes a second connector, a third connector, and a first guide. The second connector and the third connector are both disposed on the base and spaced apart along the first direction. The first guide extends along the first direction and its two ends along the first direction are respectively connected to the second connector and the third connector. The second fixing assembly is connected to the first guide and slides relative to the first guide along the first direction.

[0011] In an optional embodiment, the first guide member is rotatably connected to the second connector and the third connector at both ends, and rotates about the first direction. The second fixing component includes a fourth connector and a second fixing member connected to the fourth connector. The second fixing member is used to fix the rotor. The fourth connector is threadedly connected to the first guide member.

[0012] In an optional embodiment, the first fixing component further includes a second guide member connected to the first fixing component and disposed at one end of the first fixing component near the second fixing component along the first direction. The second guide member extends along the first direction and is disposed at the central axis of the stator.

[0013] In an optional embodiment, the guide assembly further includes a slider and a third guide, the third guide being connected to the base and extending along the first direction, the slider being slidably connected to the third guide and sliding relative to the third guide along the first direction, and the second fixing assembly being connected to the slider.

[0014] In an optional embodiment, the second connector is disposed close to the first fixing member, and the first fixing component further includes a first limiting member disposed on the side of the second connector close to the first fixing member along the first direction.

[0015] In an optional embodiment, the first fixing component further includes a second limiting member, which is connected to the base and is respectively disposed on both sides of the first fixing component along the first direction.

[0016] Secondly, this application provides a manufacturing apparatus for a permanent magnet synchronous motor, comprising: an assembly fixture as described in any of the foregoing embodiments.

[0017] The assembly tooling of this application has the following advantages:

[0018] In the assembly fixture of this application, the stator can be fixed by the first fixing component and the rotor can be fixed by the second fixing component. The fixing effect of the fixing components reduces the influence of magnetic attraction on the assembly of the rotor and stator, facilitating subsequent assembly of the rotor and stator. Simultaneously, it ensures that the central axis of the stator and the axis of the rotor are both parallel to the first direction and coincidentally, further improving the convenience of rotor-stator assembly. During rotor-stator assembly, the second fixing component slides relative to the guide component along the first direction, and the second fixing component and the first fixing component are aligned along the first direction... The arrangement of the two fixing components allows the second fixing component to gradually approach the first fixing component along the first direction when it moves relative to the guide component. This, in turn, allows the rotor to gradually approach the stator along the first direction, ultimately achieving the assembly of the rotor and stator. During this process, the guide component guides the movement of the second fixing component, ensuring that it always moves along the first direction. This resists the influence of magnetic attraction on the assembly of the rotor and stator, reducing the probability of a violent collision between the rotor and stator. Furthermore, this assembly process does not require manual assembly, preventing installers from being injured by strong magnetic forces during the assembly process. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0038] Reference Figure 1 as well as Figure 2 As shown, the assembly fixture 10 involved in the embodiment of this application has a first direction x. The assembly fixture 10 includes: a base 100, a first fixing component 200, a guide component 300, and a second fixing component 400.

[0039] Specifically, the first fixing component 200 is connected to the base 100; the guide component 300 is connected to the base 100 and extends along the first direction x, and the guide component 300 is disposed on one side of the first fixing component 200 along the first direction x; the second fixing component 400 is connected to the guide component 300 and is spaced apart from the first fixing component 200 along the first direction x, and the second fixing component 400 slides relative to the guide component 300 along the first direction x; wherein, the first fixing component 200 is used to fix the stator 20 and to make the central axis of the stator 20 parallel to the first direction x, and the second fixing component 400 is used to fix the rotor 30 and to make the central axis of the rotor 30 coincide with the central axis of the stator 20.

[0040] It should be noted that the first direction x is Figure 1 The direction indicated by x in the middle.

[0041] In the assembly fixture 10 of this application, the stator 20 can be fixed by the first fixing component 200, and the rotor 30 can be fixed by the second fixing component 400. The fixing effect of the fixing components reduces the influence of magnetic attraction on the assembly of the rotor 30 and stator 20, facilitating subsequent assembly of the rotor 30 and stator 20. Simultaneously, both the central axis of the stator 20 and the axis of the rotor 30 are parallel to the first direction x, and their central axes coincide. This further improves the convenience of assembling the rotor 30 and stator 20. During the assembly of the rotor 30 and stator 20, the second fixing component 400 slides relative to the guide component 300 along the first direction x, and the second fixing component 400 and the first fixing component 200... The second fixing component 400 is spaced along the first direction x. Therefore, when the second fixing component 400 moves relative to the guide component 300 along the first direction x, the second fixing component 400 can gradually move closer to the first fixing component 200 along the first direction x. This allows the rotor 30 to gradually move closer to the stator 20 along the first direction x, ultimately achieving the assembly of the rotor 30 and the stator 20. During this process, the guide component 300 guides the movement of the second fixing component 400, ensuring that the second fixing component 400 always moves along the first direction x. This resists the influence of magnetic attraction on the assembly of the rotor 30 and the stator 20, thereby reducing the probability of a violent collision between the rotor 30 and the stator 20. In addition, this assembly process does not require manual assembly, which can prevent installers from being injured by strong magnetic force during the assembly process.

[0042] Reference Figure 3 as well as Figure 4As shown, the assembly fixture 10 also has a second direction y, which intersects with the first direction x. The first fixing component 200 includes a first fixing member 210 and a first connecting member 220. The first connecting member 220 is connected to the base 100. The first fixing member 210 is rotatably connected to the first connecting member 220 and can rotate relative to the first connecting member 220 about the second direction y to a first position or a second position. The first fixing member 210 is used to fix the stator 20.

[0043] When the first fixing member 210 rotates relative to the first connecting member 220 about the second direction y to the first position, the first fixing member 210 is used to make the central axis of the stator 20 parallel to the first direction x, and the first fixing member 210 rotates from the first position about the second direction y in a direction away from the second fixing component 400 to the second position.

[0044] It should be noted that the second direction y is Figure 1 The direction indicated by y in the middle.

[0045] In this embodiment, the stator 20 can be fixed by the first fixing member 210 to resist the magnetic attraction force on the stator 20 during assembly, and the first fixing member 210 is connected to the base 100 by the first connecting member 220 to improve the structural stability of the first fixing member 210. Since the first fixing member 210 is rotatably connected to the first connecting member 220 and can rotate relative to the first connecting member 220 about the second direction y to a first position or a second position, the first fixing member 210 can be placed in different positions by rotating about the first connecting member 220. When a fixing member rotates relative to the first connecting member 220 about the second direction y to the first position, the first fixing member 210 is vertical. The first fixing member 210 is perpendicular to the plane formed by the first direction x and the second direction y. At this time, the central axis of the stator 20 is parallel to the first direction x, so that the central axis of the stator 20 and the rotor 30 coincide, thereby facilitating the assembly of the stator 20 and the rotor 30. When the first fixing member 210 rotates from the first position to the second position around the second direction y in a direction away from the second fixing component 400, the first fixing member 210 can lie flat on the base 100. Since the stator 20 is relatively heavy, when the first fixing member 210 lies flat on the base 100, it is easy to fix the stator 20 to the first fixing member 210, so as to save time and effort in the process of fixing the stator 20.

[0046] Reference Figure 3 As shown, the first fixing component 200 also includes a fastener 230. When the first fixing member 210 rotates relative to the first connecting member 220 about the second direction y to the first position, the fastener 230 is connected to the first fixing member 210 and the first connecting member 220.

[0047] In this embodiment, the first fixing member 210 is positioned in the second position to facilitate fixing the stator 20 to the first fixing member 210. After fixing the stator 20, the first fixing member 210 is rotated relative to the first connecting member 220 around the second direction y to the first position, so that the central axis of the stator 20 is parallel to the first direction x and coincides with the central axis of the rotor 30, so as to facilitate the assembly of the stator 20 and the rotor 30. During this process, when the first fixing member 210 rotates relative to the first connecting member 220 around the second direction y to the first position, the first fixing member 210 and the first connecting member 220 can be fixed by the fastener 230 to improve the structural stability of the first fixing member 210 at the first position, thereby improving the ability of the first fixing member 210 to resist magnetic attraction.

[0048] Specifically, the fastener 230 is a fastening bolt, and the fastening bolt is threadedly connected to the first fixing member 210 and the first connecting member 220.

[0049] Specifically, refer to Figure 4 As shown, in this embodiment, the first fixing component 200 further includes a push handle 270, which is connected to the first fixing member 210 and is used to be respectively disposed on both sides of the first fixing member 210 with the stator 20. The first fixing member 210 can be rotated relative to the first connecting member 220 about the second direction y by pushing or pulling the handle, so as to save time and effort in the process of pushing the first fixing member 210.

[0050] Reference Figure 3 As shown, the guide assembly 300 includes a second connector 310, a third connector 320, and a first guide 330. The second connector 310 and the third connector 320 are both disposed on the base 100 and are spaced apart along the first direction x. The first guide 330 extends along the first direction x, and its two ends along the first direction x are respectively connected to the second connector 310 and the third connector 320. The second fixing assembly 400 is connected to the first guide 330 and slides relative to the first guide 330 along the first direction x.

[0051] In this embodiment, since the first guide member 330 extends along the first direction x, and the second fixing component 400 is connected to the first guide member 330 and slides relative to the first guide member 330 along the first direction x, the first guide member 330 can guide the movement of the second fixing component 400, ensuring that the second fixing component 400 always moves along the first direction x, thereby resisting the influence of magnetic attraction on the assembly of the rotor 30 and the stator 20. Since the second connecting member 310 and the third connecting member 320 are spaced apart on the base 100 along the first direction x, and the two ends of the first guide member 330 along the first direction x are respectively connected to the second connecting member 310 and the third connecting member 320, the first guide member 330 can be connected to the base 100 through the second connecting member 310 and the third connecting member 320, thereby improving the structural stability of the first guide member 330 and improving the ability of the first guide member 330 to resist magnetic attraction.

[0052] Reference Figure 3 as well as Figure 4 As shown, the first guide member 330 is rotatably connected to the second connector 310 and the third connector 320 at both ends, and rotates about the first direction x. The second fixing assembly 400 includes a fourth connector 410 and a second fixing member 420 connected to the fourth connector 410. The second fixing member 420 is used to fix the rotor 30. The fourth connector 410 is threadedly connected to the first guide member 330.

[0053] In this embodiment, since the first guide member 330 can rotate around the first direction x, and the fourth connector 410 is threadedly connected to the first guide member 330, when the first guide member 330 rotates around the first direction x, it can drive the fourth connector 410 to move relative to the first guide member 330 along the first direction x. Since the second fixing member 420 is connected to the fourth connector 410, when the fourth connector 410 moves along the first direction x, it can drive the second fixing member 420 to move along the first direction x, thereby realizing the movement of the second fixing member 420 relative to the first fixing assembly 200 along the first direction x. Thus, the second fixing member 420 drives the rotor 30 to gradually approach the stator 20 along the first direction x, and finally realizes the assembly of the rotor 30 and the stator 20.

[0054] Specifically, refer to Figure 3 As shown, in this embodiment, the guide assembly 300 further includes a rotating handle 360, which is connected to the first guide member 330 and can rotate the first guide member 330 about the first direction x by rotating the rotating handle 360.

[0055] Reference Figure 3 as well as Figure 4As shown, the first fixing component 200 also includes a second guide 240, which is connected to the first fixing component 210 and disposed at one end of the first fixing component 210 near the second fixing component 400 along the first direction x. The second guide 240 extends along the first direction x and is disposed at the central axis of the stator 20.

[0056] It should be noted that, referring to Figure 1 as well as Figure 2 As shown, in the permanent magnet synchronous motor, the stator 20 is provided with a receiving cavity 21. When the rotor 30 is assembled with the stator 20, the rotor 30 is set in the receiving cavity 21. The rotor 30 is provided with a central through hole 31. The central axis of the central through hole 31 coincides with the central axis of the rotor 30. The second guide member 240 is set in the receiving cavity 21 and passes through the central through hole 31.

[0057] In this embodiment, since the second guide member 240 is connected to the first fixing member 210 and is disposed at one end of the first fixing member 210 near the second fixing assembly 400 along the first direction x, when the stator 20 is fixed to the first fixing member 210, the stator 20 can be sleeved on the second guide member 240, and the central axis of the stator 20 coincides with the central axis of the second guide member 240, so as to facilitate the positioning of the stator 20. At the same time, since the second guide member 240 extends along the first direction x, when the rotor 30 moves along the first direction x under the drive of the second fixing assembly 400, the rotor 30 can be sleeved on the second guide member 240, so that the rotor 30 moves relative to the second guide member 240 along the first direction x. Thus, the second guide member 240 further provides guidance for the rotor 30, ensuring that the rotor 30 always moves along the first direction x, thereby resisting the influence of magnetic attraction on the movement of the rotor 30 along the first direction x and reducing the impact on the assembly of the rotor 30 and the stator 20.

[0058] Reference Figure 3 as well as Figure 4 As shown, the guide assembly 300 also includes a slider 340 and a third guide 350. The third guide 350 is connected to the base 100 and extends along the first direction x. The slider 340 is slidably connected to the third guide 350 and slides relative to the third guide 350 along the first direction x. The second fixing assembly 400 is connected to the slider 340.

[0059] In this embodiment, since the slider 340 is slidably connected to the third guide 350 and slides relative to the third guide 350 along the first direction x, and the second fixing component 400 is connected to the slider 340, when the slider 340 slides relative to the third guide 350 along the first direction x, the second fixing component 400 can be moved along the first direction x by the slider 340, thereby driving the rotor 30 to move along the first direction x. Since the third guide 350 extends along the first direction x, it can guide the sliding of the slider 340, ensuring that the slider 340 always slides along the first direction x, thereby further ensuring that the second fixing component 400 can always move along the first direction x, thus resisting the influence of magnetic attraction on the assembly of the rotor 30 and the stator 20.

[0060] Reference Figure 3 As shown, the second connector 310 is disposed close to the first fixing member 210. The first fixing component 200 also includes a first limiting member 250. The first limiting member 250 is disposed on the side of the second connector 310 close to the first fixing member 210 along the first direction x. When the first fixing member 210 rotates relative to the first connector 220 around the second direction y to the first position, the first limiting member 250 abuts against the first fixing member 210.

[0061] In this embodiment, since the second connecting member 310 is located close to the first fixing member 210, and the first limiting member 250 is located on the side of the second connecting member 310 close to the first fixing member 210 along the first direction x, when the first fixing member 210 rotates relative to the first connecting member 220 around the second direction y to the first position, the first limiting member 250 can abut against the first fixing member 210. In this way, the abutment between the first limiting member 250 and the first fixing member 210 can limit the rotation of the first fixing member 210, so that the first fixing member 210 can stop rotating at the first position, ensuring the accuracy of the position of the first fixing member 210. At the same time, the first limiting member 250 can isolate the first fixing member 210 and the second connecting member 310, so as to avoid the collision between the first fixing member 210 and the second connecting member 310 during the rotation of the first fixing member 210.

[0062] Reference Figure 4 As shown, the first fixing component 200 also includes a second limiting member 260. The second limiting member 260 is connected to the base 100 and is respectively disposed on both sides of the first fixing member 250 along the first direction x. When the first fixing member 210 rotates relative to the first connecting member 220 around the second direction y to the second position, the second limiting member 260 abuts against the first fixing member 210.

[0063] In this embodiment, since the second limiting member 260 and the first limiting member 250 are respectively disposed on both sides of the first fixing member 210 along the first direction x, when the first fixing member 210 rotates relative to the first connecting member 220 around the second direction y to the second position, the second limiting member 260 can abut against the first fixing member 210. In this way, the abutment between the second limiting member 260 and the first fixing member 210 can limit the rotation of the first fixing member 210, so that the first fixing member 210 can stop rotating at the second position, ensuring the accuracy of the position of the first fixing member 210. At the same time, the second limiting member 260 can isolate the first fixing member 210 from the base 100, so as to avoid the collision between the first fixing member 210 and the base 100 during the rotation of the first fixing member 210.

[0064] This application provides a manufacturing apparatus for a permanent magnet synchronous motor, including the assembly fixture 10 described above.

[0065] In the manufacturing apparatus for the permanent magnet synchronous motor of this application, since the assembly fixture 10 described above can reduce the influence of magnetic attraction on the assembly of the rotor 30 and the stator 20, the manufacturing apparatus for the permanent magnet synchronous motor of this application can have a better product yield.
