It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

In addition, the terms "first" and "second" are merely used to distinguish in description and have no special meaning.

[0053] At present, the assembly tool for assembling the rotor core and the rotating shaft in the prior art can sequentially assemble each rotor core to the rotating shaft according to a certain deflection angle rule, but it depends on automatic assembly equipment, and the cost is high for small batch trial production or small scale production; secondly, the efficiency and precision of assembling the rotor core and the rotating shaft in the prior art need to be improved.

[0054] As shown in Figures 1-3 The present application provides a skew pole rotor assembly tool. The skew pole rotor includes two rotor core groups 100, and each rotor core group 100 includes a plurality of rotor cores 110. The inner peripheral wall of each rotor core 110 is concavely provided with a plurality of key grooves 1101, and the plurality of key grooves 1101 are sequentially and spacedly distributed along the first clockwise direction around the central axis of the rotor core 110. The number of key grooves 1101 of each rotor core 110 corresponds to the number of rotor cores 110 of each rotor core group 100. The skew pole rotor assembly tool includes a positioning column 1 and a rotating positioning structure. The outer peripheral surface of the positioning column 1 is convexly provided with a positioning key 11 extending to both ends in the axial direction. The positioning key 11 can be inserted and positioned with the key groove 1101 of the rotor core 110. The rotating positioning structure includes a rotating disc 2 and two sets of elastic expansion positioning members 3 arranged on the rotating disc 2. The positioning column 1 is coaxially and rotationally connected to the first end of the rotating disc 2 in the axial direction. The two sets of elastic expansion positioning members 3 are symmetrically distributed and located at the second end of the rotating disc 2 in the axial direction. The two sets of elastic expansion positioning members 3 are configured to selectively make one set of elastic expansion positioning members 3 in a first working state of being retracted into the inside of the rotating disc 2, and the other set of elastic expansion positioning members 3 in a second working state of being partially extended out of the peripheral wall of the rotating disc 2. The elastic expansion positioning member 3 in the second working state can be inserted and positioned with the rotor core 110, and make one key groove 1101 of the rotor core 110 directly face the positioning key 11.

[0055] The two rotor core groups 100 are respectively referred to as a first rotor core group and a second rotor core group. The two sets of elastic expansion positioning members 3 are respectively referred to as a first elastic expansion positioning member group and a second elastic expansion positioning member group.

[0056] An example is sequentially assembling the first rotor core group and the second rotor core group.

[0057] When assembling two rotor core assemblies 100 using the skew-pole rotor assembly tool, the positioning column 1 is fixed. The two sets of elastically retractable positioning members 3 are adjusted so that the elastically retractable positioning members 3 of the first elastically retractable positioning member group are in the second working state, and the elastically retractable positioning members 3 of the second elastically retractable positioning member group are in the first working state. The first rotor core 110 of the first rotor core group is sleeved on the turntable 2, so that the elastically retractable positioning members 3 of the first elastically retractable positioning member group are plugged and positioned with the rotor core 110. It can be understood that at this time, the relative position of the rotor core 110 and the turntable 2 along the circumferential direction is fixed. The turntable 2 is then rotated so that the first keyway 1101 of the rotor core 110 along the first clockwise direction is directly above and opposite the positioning key 11. At this time, the rotor core 110 is axially slid downward, so that the first keyway 1101 of the rotor core 110 along the first clockwise direction is plugged and positioned with the positioning key 11, thereby completing the relative position of the first rotor core 110 and the positioning column 1. The second rotor core 110 of the first rotor core group is sleeved onto the turntable 2, so that the elastically retractable positioning member 3 of the first elastically retractable positioning member group is inserted and positioned with the rotor core 110. The turntable 2 is then rotated so that the second keyway 1101 on the rotor core 110 along the first clockwise direction is directly above and opposite the positioning key 11. At this time, the rotor core 110 is axially slid downward to insert and position the second keyway 1101 along the first clockwise direction with the positioning key 11, thereby completing the relative positioning of the second rotor core 110 and the positioning post 1. This process is repeated repeatedly until all the rotor cores 110 of the first rotor core group are assembled on the positioning post 1.

[0058] Then adjust the two groups of elastic telescopic positioning members 3 so that the elastic telescopic positioning members 3 of the first elastic telescopic positioning member group are in the first working state, and the elastic telescopic positioning members 3 of the second elastic telescopic positioning member group are in the second working state. Sleeve the first rotor core 110 of the second rotor core group on the turntable 2 so that the elastic telescopic positioning members 3 of the second elastic telescopic positioning member group are plugged and positioned with the rotor core 110; then rotate the turntable 2 so that the first keyway 1101 along the third clockwise direction on the rotor core 110 is directly above and opposite to the positioning key 11. At this time, slide the rotor core 110 axially downward so that the first keyway 1101 along the third clockwise direction on the rotor core 110 can be plugged and positioned with the positioning key 11, thereby completing the relative positioning of the first rotor core 110 and the positioning column 1. The second rotor core 110 of the second rotor core group is sleeved on the turntable 2, so that the elastically retractable positioning member 3 of the second elastically retractable positioning member group is plugged into and positioned with the rotor core 110. Then, the turntable 2 is rotated. The second keyway 1101 along the third clockwise direction on the rotor core 110 is located directly above and opposite the positioning key 11. At this time, the rotor core 110 is axially slid downward, and the second keyway 1101 along the third clockwise direction on the rotor core 110 is plugged into and positioned with the positioning key 11, thereby completing the relative positioning of the second rotor core 110 and the positioning post 1. This process is repeated until all the rotor cores 110 of the second rotor core group are assembled on the positioning post 1. The first clockwise direction and the third clockwise direction are opposite clockwise directions.

[0059] Specifically, the multiple keyways 1101 of each rotor core 110 are arranged to be spaced apart in sequence along the first clockwise direction around the central axis of the rotor core 110, so that when the front side of the rotor core 110 faces upward, the distribution positions of the multiple keyways 1101 can be symmetrical with the distribution positions of the multiple keyways 1101 when the rear side of the rotor core 110 faces upward about the fixed symmetry plane. The central axis of the rotor core 110 is located on the fixed symmetry plane. It can be understood that when the rear side of the rotor core 110 faces upward, the multiple keyways 1101 are spaced apart in sequence along the third clockwise direction. Therefore, when assembling the first rotor core group, all the rotor cores 110 of the first rotor core group are placed on the turntable 2 with the front side facing upward; when assembling the second rotor core group, all the rotor cores 110 of the second rotor core group are placed on the turntable 2 with the rear side facing upward. Alternatively, when assembling the first rotor core assembly, each rotor core 110 of the first rotor core assembly is placed on the turntable 2 with its reverse side facing upward; when assembling the second rotor core assembly, each rotor core 110 of the second rotor core assembly is placed on the turntable 2 with its front side facing upward. This ensures that the positions and number of grooves on each rotor core 110 are the same, effectively reducing the number of keyways 1101 on the rotor core 110. This effectively reduces the difficulty and cost of producing the rotor core 110, and also reduces the difficulty of assembling the rotor core 110.

[0060] Secondly, the two groups of elastic telescopic positioning members 3 are symmetrically distributed and are both located at the second end of the turntable 2 in the axial direction. They are symmetrically distributed along the first symmetry line, and the first symmetry line intersects the central axis of the turntable 2 at right angles. This ensures that the position where the rotor core 110 is plugged in and positioned with one group of elastic telescopic positioning members 3 when the front side of the rotor core 110 is facing upward is the same as the position where the rotor core 110 is plugged in and positioned with the other elastic telescopic positioning member 3 when the back side of the rotor core 110 is facing upward. This ensures that the setting positions and number of the plug-in positioning positions on each rotor core 110 are the same, and can effectively reduce the number of plug-in positioning positions on the rotor core 110. As a result, the structures of the rotor cores 110 of the two rotor core groups 100 are the same, which can further reduce the production difficulty and production cost of the rotor core 110, and can also further reduce the difficulty of assembling the rotor core 110.

[0061] Therefore, compared with the existing technology, the skewed pole rotor assembly device has a simple structure and is convenient for assembling small-batch trial-production or small-scale production of skewed pole rotors; secondly, it can quickly and accurately assemble each rotor core 110 into a whole according to the required deflection angle rule; thirdly, it can effectively reduce the production difficulty and production cost of the rotor core 110.

[0062] It can be understood that when the rotor core 110 is mounted on the turntable 2, the central axis of the rotor core 110, the rotation center line of the rotor core 110, the central axis of the turntable 2, the rotation center line of the turntable 2, the central axis of the positioning column 1 and the rotation center line of the positioning column 1 are all collinear.

[0063] Specifically, the deflection angles of the multiple rotor cores 110 of each rotor core group 100 can be the same, gradually increase, gradually decrease, or gradually change according to a set rule. Furthermore, the spacing variation pattern of the multiple keyways 1101 of the rotor cores 110, which are sequentially spaced around the central axis of the rotor core 110 along the first clockwise direction, corresponds to the variation pattern of the deflection angles of the multiple rotor cores 110. When the deflection angles of the multiple rotor cores 110 are the same, the multiple keyways 1101 of each rotor core 110 are sequentially spaced around its own central axis along the first clockwise direction. When the deflection angles of the multiple rotor cores 110 gradually increase, the multiple keyways 1101 of each rotor core 110 are sequentially spaced around its own central axis along the first clockwise direction, and the spacing distances gradually increase accordingly. When the deflection angles of the multiple rotor cores 110 gradually decrease, the multiple keyways 1101 of each rotor core 110 are sequentially spaced around its own central axis along the first clockwise direction, and the spacing distances gradually decrease accordingly.

[0064] Specifically, when the two rotor core assemblies 100 have the same number of rotor cores 110, the number of keyways 1101 in each rotor core 110 is the same as the number of rotor cores 110 in each rotor core assembly 100. When the two rotor core assemblies 100 have different numbers of rotor cores 110, the number of keyways 1101 in each rotor core assemblies 100 is the same as the number of rotor cores 110 in the one of the two rotor core assemblies 100 with the larger number of rotor cores 110. This arrangement allows the multiple rotor cores 110 in each rotor core assembly 100 to be assembled on the positioning column 1 according to the required deflection angle pattern.

[0065] Specifically, in this embodiment, it is exemplified that two groups of elastic telescopic positioning members 3 are symmetrically distributed along a first symmetry line, and the first symmetry line intersects the central axis of the turntable 2 at right angles.

[0066] Specifically, after the rotor cores 110 of the two rotor core groups 100 are assembled on the positioning column 1, all the rotor cores 110 on the positioning column 1 are transferred as a whole to the shaft 5 of the skew pole rotor to complete the assembly of the shaft 5 and all the rotor cores 110.

[0067] Preferably, if Figures 1-3As shown, each group of elastic telescopic positioning members 3 includes two elastic telescopic positioning members 3 distributed at intervals along the circumference of the turntable 2. The inner peripheral wall of the rotor core 110 is recessed with two positioning grooves 1102, and the two elastic telescopic positioning members 3 are arranged in a one-to-one correspondence with the two positioning grooves 1102, and the elastic telescopic positioning members 3 can be plugged into and positioned with the positioning grooves 1102. The opening shapes of the two positioning grooves 1102 are different; and / or, the opening areas of the two positioning grooves 1102 are different. By setting the number of positioning grooves 1102 to two, and the opening shapes and / or opening areas of the two positioning grooves 1102 are different, the front and back sides of each rotor core 110 can be quickly and accurately determined when assembling the rotor core 110, thereby further improving the efficiency of assembling each rotor core 110 into a whole according to the required deflection angle rule.

[0068] In this embodiment, if Figure 2 and Figure 3 As shown, preferably both positioning grooves 1102 are arc-shaped grooves, and the opening areas of the two arc-shaped grooves are different. It is understandable that the ends of the two elastic telescopic positioning members 3 in each group are also arc-shaped, and the ends of the two elastic telescopic positioning members 3 in each group are different in size.

[0069] Among them, such as Figure 1 、 Figure 2 and Figure 4 As shown, the rotational positioning structure also includes a rotating cover 4 coaxially connected to the second axial end of the rotating disc 2. The rotating cover 4 is provided with a pusher portion 41 disposed around the outer circumference of the rotating disc 2. The pusher portion 41 is provided with two communication holes 411 spaced apart along the circumference of the rotating cover 4. The two communication holes 411 are provided one for each set of two elastically retractable positioning members 3. In the second operating state, the elastically retractable positioning members 3 pass through the rotating disc 2 and the corresponding communication holes 411 to engage and position the rotor core 110.

[0070] Specifically, before assembling the rotor core 110 of the first rotor core group on the positioning column 1, the rotary cover 4 is rotated, and the push portion 41 pushes the two elastic telescopic positioning members 3 of the second elastic telescopic positioning member group to retract into the turntable 2 through the two connecting holes 411 in a one-to-one correspondence. It can be understood that in this process, the two elastic telescopic positioning members 3 of the second elastic telescopic positioning member group are elastically compressed; the rotary cover 4 is continued to be rotated until the two elastic telescopic positioning members 3 of the first elastic telescopic positioning member group are aligned with the two connecting holes 411 in a one-to-one correspondence. The two elastic telescopic positioning members 3 of the first elastic telescopic positioning member group partially extend out of the corresponding connecting holes 411 under the action of their own elastic restoring force. This puts the two elastic telescopic positioning members 3 of the first elastic telescopic positioning member group in the second working state, and the two elastic telescopic positioning members 3 of the second elastic telescopic positioning member group in the first working state. The two elastic telescopic positioning members 3 of the first elastic telescopic positioning member group can be inserted and positioned with the two positioning grooves 1102 of the rotor core 110.

[0071] Specifically, before assembling the rotor core 110 of the second rotor core group on the positioning column 1, the rotary cover 4 is rotated, and the push portion 41 pushes the two elastic telescopic positioning members 3 of the first elastic telescopic positioning member group to retract into the turntable 2 through the two connecting holes 411 in a one-to-one correspondence. It can be understood that in this process, the two elastic telescopic positioning members 3 of the first elastic telescopic positioning member group are elastically compressed; the rotary cover 4 is continued to be rotated until the two elastic telescopic positioning members 3 of the second elastic telescopic positioning member group are aligned with the two connecting holes 411 in a one-to-one correspondence. The two elastic telescopic positioning members 3 of the second elastic telescopic positioning member group partially extend out of the corresponding connecting holes 411 under the action of their own elastic restoring force. This puts the two elastic telescopic positioning members 3 of the second elastic telescopic positioning member group in the second working state, and the two elastic telescopic positioning members 3 of the first elastic telescopic positioning member group in the first working state. The two elastic telescopic positioning members 3 of the second elastic telescopic positioning member group can be inserted and positioned with the two positioning grooves 1102 of the rotor core 110.

[0072] Preferably, in this embodiment, Figure 1 、 Figure 2 and Figure 4 As shown, one of the communication holes 411 is located in the middle region of the pushing portion 41 along the circumferential direction, while the other communication hole 411 is located outside one circumferential end of the pushing portion 41. That is, the circumferential end surface of the pushing portion 41 forms part of the inner circumferential wall of the other communication hole 411. This arrangement effectively simplifies the structure of the pushing portion 41 and reduces the difficulty of manufacturing the pushing portion 41.

[0073] Alternatively, as Figures 1-3As shown, one of the rotary disc 2 and the rotary cover 4 is provided with a limiting post 21, and the other is provided with an arc-shaped limiting hole 42, and the limiting post 21 is inserted into the arc-shaped limiting hole 42. When the limiting post 21 abuts against the first end of the arc-shaped limiting hole 42 along the arc direction, the first elastic telescopic positioning member group is in the first working state, and the second elastic telescopic positioning member group is in the second working state. When the limiting post 21 abuts against the second end of the arc-shaped limiting hole 42 along the arc direction, the first elastic telescopic positioning member group is in the second working state, and the second elastic telescopic positioning member group is in the first working state. It can be understood that the center of the arc-shaped limiting hole 42 is located on the central axis of the rotary disc 2. In this way, the rotation range of the rotary cover 4 is limited, and it is convenient and efficient to adjust one group of elastic telescopic positioning members 3 to be in the first working state of being retracted into the rotary disc 2, and the other group of elastic telescopic positioning members 3 to be in the second working state of being partially extended outside the peripheral wall of the rotary disc 2. Therefore, the efficiency of assembling the rotor cores 110 into a whole according to the required deflection angle rule can be further improved.

[0074] In the embodiment, as shown in Figure 1 and Figure 3 , an example is taken that the limiting post 21 is arranged on the rotary disc 2, and the arc-shaped limiting hole 42 is arranged on the rotary cover 4. As an alternative, the arc-shaped limiting hole 42 can also be arranged on the rotary disc 2, and the limiting post 21 can be arranged on the rotary cover 4.

[0075] Further optionally, as shown in Figures 1-3 , the peripheral wall of the rotary disc 2 is provided with a limiting block 22 and two limiting surfaces 23. Along the circumferential direction of the rotary disc 2, the limiting block 22 is located between the two limiting surfaces 23, and the limiting block 22 is located in one of the communication holes 411 in the middle region of the circumferential direction of the pushing part 41. The two limiting surfaces 23 are arranged in correspondence with and can abut against the two ends of the circumferential direction of the pushing part 41. The circumferential angle between the two ends of the circumferential direction of the arc-shaped limiting hole 42 is a first circumferential angle. The circumferential angle between the two ends of the circumferential direction of the pushing part 41 is a second circumferential angle. Along the circumferential direction of the rotary disc 2, the circumferential angle between the two limiting surfaces 23 is a third circumferential angle. The third circumferential angle is the sum of the first circumferential angle and the second circumferential angle. In this way, the effect of limiting the rotation range of the rotary cover 4 can be further improved; and the rotary disc 2 can be prevented from being randomly rotated.

[0076] In the embodiment, as shown in Figure 1 , one end of the elastic telescopic positioning member 3 that can be extended out of the rotary disc 2 and the corresponding communication hole 411 is provided with a guide surface 311, and the guide surface 311 can guide the elastic telescopic positioning member 3 to retract into the interior of the rotary disc 2. In this way, the smoothness and efficiency of changing the working state of the elastic telescopic positioning member 3 by the pushing part 41 can be improved.

[0077] Preferably, in the embodiment, as shown in Figure 1As shown, the guide surface 311 is an arc-shaped surface, which not only facilitates the insertion and positioning of the elastic telescopic positioning member 3 and the positioning groove 1102, but also improves the smoothness and efficiency of the elastic telescopic positioning member 3 changing the working state through the pushing portion 41.

[0078] As an alternative, the guide surface 311 and the positioning groove 1102 may both be configured to be triangular.

[0079] Among them, such as Figures 1-3 As shown, the elastic telescopic positioning member 3 includes a positioning protrusion 31 and an elastic member 32. One end of the elastic member 32 abuts or is fixedly connected to the inside of the turntable 2, and the other end of the elastic member 32 abuts or is fixedly connected to the positioning protrusion 31. The elastic restoring force of the elastic member 32 can drive the positioning protrusion 31 to partially extend out of the outer peripheral wall of the rotary cover 4, and the positioning protrusion 31 can be inserted and positioned with the positioning groove 1102 of the rotor core 110. This arrangement allows the elastic telescopic positioning member 3 to effectively retract into the turntable 2 or partially extend out of the turntable 2. It can be understood that the end of the positioning protrusion 31 that can extend out of the outer peripheral wall of the turntable 2 is the end of the positioning protrusion 31 away from the elastic member 32, and the guide surface 311 is provided on the end of the positioning protrusion 31 away from the elastic member 32.

[0080] Specifically, in this embodiment, Figures 1-3 As shown, the elastic member 32 is exemplarily taken as a spring.

[0081] Preferably, if Figures 1-3 As shown, the turntable 2 is provided with two identification groups, and the two identification groups are symmetrically distributed and both are located at the second end of the turntable 2 along the axial direction. The two identification groups, the two groups of elastic telescopic positioning members 3 and the two rotor core groups 100 are all arranged in a one-to-one correspondence. The multiple first identifications in the identification groups are distributed in sequence along the second clockwise direction around the central axis of the turntable 2. The multiple first identifications in each identification group are arranged in a one-to-one correspondence with the multiple rotor cores 110 in a corresponding rotor core group 100. When the first identification is facing the positioning key 11, one of the key slots 1101 of the rotor core 110 can be plugged into the positioning key 11 for positioning.

[0082] The two identification groups are respectively designated as identification group A and identification group B. The first elastic telescopic positioning member group and identification group A both correspond to the first rotor core group. The second elastic telescopic positioning member group and identification group B both correspond to the second rotor core group.

[0083] Specifically, when assembling two rotor core groups 100, the two groups of elastic telescopic positioning members 3 are adjusted so that the elastic telescopic positioning members 3 of the first elastic telescopic positioning member group are in the second working state, and the elastic telescopic positioning members 3 of the second elastic telescopic positioning member group are in the first working state. The first rotor core 110 of the first rotor core group is sleeved on the turntable 2 so that the elastic telescopic positioning members 3 of the first elastic telescopic positioning member group are plugged and positioned with the rotor core 110; then the turntable 2 is rotated so that the first first mark A1 of the A mark group along the second clockwise direction is aligned with the positioning key 11. At this time, the first keyway 1101 of the rotor core 110 along the first clockwise direction is located directly above the positioning key 11 and aligned with the positioning key 11. At this time, the rotor core 110 is axially slid downward so that the first keyway 1101 of the rotor core 110 along the first clockwise direction is plugged and positioned with the positioning key 11, thereby completing the relative positioning of the first rotor core 110 and the positioning column 1. The second rotor core 110 of the first rotor core group is sleeved on the turntable 2 so that the elastic telescopic positioning member 3 of the first elastic telescopic positioning member group is plugged into and positioned with the rotor core 110; then the turntable 2 is rotated so that the second first mark A2 of the A mark group along the second clockwise direction is aligned with the positioning key 11. At this time, the second keyway 1101 along the first clockwise direction on the rotor core 110 is located directly above the positioning key 11 and aligned with the positioning key 11. The rotor core 110 is axially slid downward so that the second keyway 1101 along the first clockwise direction on the rotor core 110 is plugged into and positioned with the positioning key 11, thereby completing the relative positioning of the second rotor core 110 and the positioning column 1. This process is analogous to the above until all the rotor cores 110 of the first rotor core group are assembled on the positioning column 1. It is understandable that in this process, the second clockwise direction is the same as the first clockwise direction.

[0084] Then adjust the two groups of elastic telescopic positioning members 3 so that the elastic telescopic positioning members 3 of the first elastic telescopic positioning member group are in the first working state, and the elastic telescopic positioning members 3 of the second elastic telescopic positioning member group are in the second working state. Sleeve the first rotor core 110 of the second rotor core group on the turntable 2 so that the elastic telescopic positioning members 3 of the second elastic telescopic positioning member group are plugged and positioned with the rotor core 110; then rotate the turntable 2 so that the first first mark B4 of the B mark group along the second clockwise direction is aligned with the positioning key 11. At this time, the first keyway 1101 of the rotor core 110 along the third clockwise direction is located directly above the positioning key 11 and aligned with the positioning key 11. Slide the rotor core 110 axially downward so that the first keyway 1101 of the rotor core 110 along the third clockwise direction is plugged and positioned with the positioning key 11, thereby completing the relative positioning of the first rotor core 110 and the positioning column 1. The second rotor core 110 of the second rotor core group is sleeved on the turntable 2 so that the elastic telescopic positioning member 3 of the second elastic telescopic positioning member group is plugged into and positioned with the rotor core 110; then the turntable 2 is rotated so that the second first mark B5 of the B mark group along the second clockwise direction is aligned with the positioning key 11. At this time, the second keyway 1101 of the rotor core 110 along the third clockwise direction is located directly above the positioning key 11 and aligned with the positioning key 11. The rotor core 110 is axially slid downward so that the second keyway 1101 of the rotor core 110 along the third clockwise direction is plugged into and positioned with the positioning key 11, thereby completing the relative positioning of the second rotor core 110 and the positioning column 1. This process is analogous to the above until all the rotor cores 110 of the second rotor core group are assembled on the positioning column 1. It is understandable that in this process, the second clockwise direction and the third clockwise direction are the same clockwise direction.

[0085] Two marker groups are symmetrically distributed and located at the second end of the turntable along the axial direction. The multiple first markers of one marker group correspond to the multiple key slots 1101 of the rotor core 110 when the front side is facing upward, while the multiple first markers of the other marker group correspond to the multiple key slots 1101 of the rotor core 110 when the back side is facing upward. This allows the rotor cores 110 to be assembled into a whole quickly and accurately according to the required deflection angle.

[0086] Specifically, the spacing variation pattern of the multiple keyways 1101 of the rotor core 110 spaced in sequence along the first clockwise direction around the central axis of the rotor core 110 corresponds to the spacing variation pattern of the multiple first marks of the identification group spaced in sequence along the second clockwise direction. When the multiple keyways 1101 of the rotor core 110 are equally spaced in sequence along the first clockwise direction around its own central axis, the multiple first marks of the identification group are equally spaced in sequence along the second clockwise direction. When the multiple keyways 1101 of the rotor core 110 are spaced in sequence along the first clockwise direction around its own central axis and the spacing distance gradually increases, the multiple first marks of the identification group are spaced in sequence along the second clockwise direction and the spacing distance correspondingly gradually increases. When the multiple keyways 1101 of the rotor core 110 are spaced in sequence along the first clockwise direction around its own central axis and the spacing distance gradually decreases, the multiple first marks of the identification group are spaced in sequence along the second clockwise direction and the spacing distance correspondingly gradually decreases.

[0087] In this embodiment, if Figures 1-3 As shown, exemplarily, each rotor core group 100 includes three rotor cores 110, each rotor core 110 is provided with three keyways 1101 distributed in sequence at equal intervals along the first clockwise direction around its own central axis, and each identification group is provided with three first identification positions distributed in sequence at equal intervals along the second clockwise direction. In this embodiment, the exemplary setting of each first identification is a triangular identification. Specifically, the three first identifications of the A identification group are marked with A1, A2 and A3 in sequence along the first clockwise direction around the central axis of the turntable 2. The three first identifications of the B identification group are marked with B4, B5 and B6 in sequence along the third clockwise direction around the central axis of the turntable 2. It can be understood that the identification marked with A1 is the first identification in the A identification group. The identification marked with B4 is the first identification in the B identification group. As an alternative, each first identification can also be set to be an arrow identification or a color identification.

[0088] In this embodiment, if Figure 3 As shown, for example, two identification groups are symmetrically distributed along the second symmetry line, and the second symmetry line intersects the central axis of the turntable 2 perpendicularly. Figure 3 As shown, the first symmetry line L and the second symmetry line are collinear as an example.

[0089] Preferably, if Figures 1-3As shown, along the axial direction of the positioning post 1, a second marking 111 is provided on the positioning key 11 at the end near the turntable 2. Rotating the turntable 2 aligns the first markings on the turntable 2 with the second markings 111. This further improves the accuracy and efficiency of positioning the deflection angle of the rotor core 110. In this embodiment, the second marking 111 is exemplarily a triangle. Alternatively, the second marking 111 may be an arrow or color marking.

[0090] Among them, such as Figures 4-7 As shown, the skewed-pole rotor also includes a rotating shaft 5, which is coaxially rotatably plugged into the end of the positioning post 1 axially away from the turntable 2. The rotating shaft 5 is provided with an axially extending connecting key 51. The skewed-pole rotor assembly tool also includes a guide key 6. Along the axial direction of the positioning post 1, one end of the guide key 6 is detachably connected to the end of the positioning key 11 away from the turntable 2, and the other end of the guide key 6 is detachably connected to the connecting key 51. The guide key 6 is used to guide the two rotor core assemblies 100 to be sleeved onto the rotating shaft 5.

[0091] After both rotor core assemblies 100 are assembled on the positioning column 1, one axial end of the rotating shaft 5 is inserted into the end of the positioning column 1 axially away from the turntable 2. The rotating shaft 5 is then rotated so that the positioning key 11 and the connecting key 51 are aligned. The guide key 6 is then connected between the positioning key 11 and the connecting key 51, so that the positioning key 11, the guide key 6, and the connecting key 51 form a continuous key line. The rotor core 110 assembled on the positioning column 1 is then pushed onto the rotating shaft 5. It can be understood that the key slots 1101 on each rotor core 110 that are keyed to the positioning key 11 are now keyed to the connecting key 51 on the rotating shaft 5. This completes the assembly of the skewed-pole rotor. Therefore, this arrangement allows for the quick and efficient assembly of the rotating shaft 5 and each rotor core 110 while effectively preventing changes in the deflection angle of any rotor core 110.

[0092] It is understood that when one axial end of the rotating shaft 5 is inserted into the end of the positioning post 1 axially away from the turntable 2, the central axis of the rotating shaft 5 is collinear with the central axis of the positioning post 1. When the positioning key 11, the guide key 6, and the connecting key 51 form a continuous key line, the three outer side walls of the positioning key 11, the three outer side walls of the guide key 6, and the three outer side walls of the connecting key 51 are coplanar and correspond one to one.

[0093] Specifically, if Figures 4-7 As shown, the end of the positioning key 11 away from the turntable 2 is provided with a first connecting groove 112, and one end of the guide key 6 is provided with a first connecting block 61, which can be plugged into the first connecting groove 112. When the first connecting block 61 and the first connecting groove 112 are plugged into each other, the positioning key 11 and the guide key 6 form a continuous key.

[0094] In this embodiment, if Figures 4-7As shown, the exemplary first connecting groove 112 includes a first sub-groove 1121 and a second sub-groove 1122 connected in communication, and the connecting surface 1123 is formed at the communication of the first sub-groove 1121 and the second sub-groove 1122. The first connecting block 61 includes a first sub-block 611 and a second sub-block 612 connected in communication. The first sub-block 611 is inserted into the first sub-groove 1121, and the second sub-block 612 is inserted into the second sub-groove 1122. In the direction from the positioning key 11 to the connecting key 51 along the axial direction of the positioning column 1, the first sub-block 611 is overlapped with the connecting surface 1123. In this way, when the guide key 6 is assembled to the positioning key 11, the guide key 6 can be prevented from falling off. As an alternative, the first connecting groove 112 can be concavely formed on the end surface of the positioning key 11 away from the rotating disc 2, and the first connecting block 61 is inserted into the first connecting groove 112 along the axial direction of the positioning column 1. In this way, the relative positions of the connecting key 51 and the guide key 6 can also be positioned.

[0095] Specifically, as shown in FIG. 1, the guide key 6 is provided with a first connecting groove 61 at one end thereof, and the connecting key 51 is inserted into the first connecting groove 61. In this way, the guide key 6 and the connecting key 51 are connected in communication. Figures 4-7 As shown, the other end of the guide key 6 is provided with a second connecting groove 62, and the second connecting groove 62 is capable of being inserted into the connecting key 51. When the second connecting groove 62 is inserted into one end of the connecting key 51, the guide key 6 and the connecting key 51 form a continuous key. In the present embodiment, the exemplary second connecting groove 62 is an arc-shaped groove, and the two ends of the connecting key 51 along the length direction are arc-shaped. As an alternative, the second connecting groove 62 is a rectangular groove, and the connecting key 51 is rectangular.

For those skilled in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the scope of the present application.
