[0024] 1. The slant-stage rotor assembly tool is provided with multiple keyways of each rotor core, which are sequentially spaced and distributed along the first clockwise direction around its own central axis, and two groups of elastic telescopic positioning parts are symmetrically distributed and both located at the second end of the turntable along the axial direction.

By analogy, multiple rotor cores of each rotor core group can be assembled on the positioning column. Compared with the prior art, the structure is simple, convenient for assembling small-batch trial production or small-scale production of slant-stage rotors, and each rotor core can be quickly and accurately assembled into a whole according to the required deflection angle law, and can effectively reduce the production difficulty and production cost of the rotor core.

[0025] 2. By setting the number of positioning grooves to two, and the opening shapes and / or opening areas of the two positioning grooves are different, the front and back sides of each rotor core can be quickly and accurately determined when assembling the rotor core, thereby further improving the efficiency of assembling the rotor cores into a whole according to the required deflection angle rule.

[0026] 3. By setting a pushing part, in the process of rotating the rotating cover, the pushing part can synchronously push one of the two groups of elastic telescopic positioning parts to retract into the rotating disk, and the two elastic telescopic positioning parts of the other group of elastic telescopic positioning parts extend out from the two connecting holes one by one, so that when the inclined-stage rotor is sleeved on the rotating disk, the relative position of the rotating disk and the inclined-stage rotor can be limited.

[0027] 4. By setting a limit column and an arc-shaped limit hole, during the rotation of the rotating cover, the limit column can abut against one end or the other end of the arc-shaped limit hole along the arc direction to limit the rotation range of the rotating cover, which is convenient for quick and efficient adjustment of one group of elastic telescopic positioning parts in the first working state retracted into the interior of the turntable, and the other group of elastic telescopic positioning parts in the second working state partially extending from the outer peripheral wall of the turntable.

[0028] 5. By providing a guide surface on the elastic telescopic positioning member, the smoothness and efficiency of the pushing part pushing the elastic telescopic positioning member to change the working state during the rotation of the rotary cover can be improved.

[0029] 6. By setting two identification groups corresponding to two rotor core groups, it is possible to intuitively determine whether the rotor core is rotated into place through the first identification, thereby effectively improving the accuracy and efficiency of positioning the deflection angle of the rotor core.

[0030] 7. By aligning the second mark with the first mark on the rotor core, the accuracy and efficiency of positioning the deflection angle of the rotor core can be further improved.

[0031] 8. All rotor cores on the positioning column are transferred to the rotating shaft as a whole through the guide key, so that the rotating shaft and all rotor cores can be assembled into a stepped rotor, and the deflection angle of any rotor core can be effectively prevented from changing.

[0032] 9. Connect the positioning key and the guide key through the first connecting groove and the first connecting block to form a continuous key to guide all the rotor cores to be transferred to the rotating shaft as a whole.

[0033] 10. The guide key and the connecting key are connected through the second connecting groove to form a continuous key, guiding all the rotor cores to be transferred to the rotating shaft as a whole. BRIEF DESCRIPTION OF THE DRAWINGS

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

[0053] At present, although the assembly tooling for assembling the rotor core and the rotating shaft in the existing technology can deflect and assemble each rotor core on the rotating shaft in sequence according to a certain deflection angle rule, it mostly relies on automated assembly equipment, which is costly for small-batch trial production or small-scale production; secondly, the efficiency and accuracy of assembling the rotor core and the rotating shaft in the existing technology need to be improved.

[0054] like Figure 1-3 As shown, the present invention provides a slanted rotor assembly tool. The slanted rotor includes two rotor core groups 100, and each rotor core group 100 includes a plurality of rotor cores 110. The inner circumferential wall of each rotor core 110 is concavely provided with a plurality of key slots 1101, and the plurality of key slots 1101 are sequentially spaced and distributed along the first clockwise direction around the central axis of the rotor core 110, and the number of key slots 1101 of each rotor core 110 corresponds to the number of rotor cores 110 of each rotor core group 100. The slanted rotor assembly tool includes a positioning column 1 and a rotation positioning structure. Among them, the outer circumferential surface of the positioning column 1 is convexly provided with a positioning key 11 extending to both ends along the axial direction. The positioning key 11 can be inserted and positioned with the key slot 1101 of the rotor core 110. The rotation positioning structure includes a turntable 2 and two groups of elastic telescopic positioning members 3 arranged on the turntable 2. The positioning column 1 is coaxially rotatably connected to the first end of the turntable 2 along the axial direction. The two groups of elastic telescopic positioning members 3 are symmetrically distributed and are both located at the second end of the turntable 2 along the axial direction. The two groups of elastic telescopic positioning members 3 are configured to selectively enable one group of the elastic telescopic positioning members 3 to be in a first working state in which the group is retracted into the inside of the turntable 2, and the other group of the elastic telescopic positioning members 3 to be in a second working state in which the group is partially extended out of the outer peripheral wall of the turntable 2. The elastic telescopic positioning members 3 in the second working state can be inserted and positioned with the rotor core 110, and one of the key slots 1101 of the rotor core 110 is directly opposite to the positioning key 11.

[0055] The two rotor core groups 100 are respectively recorded as the first rotor core group and the second rotor core group. The two groups of elastic telescopic positioning members 3 are respectively recorded as the first elastic telescopic positioning member group and the second elastic telescopic positioning member group.

[0056] As an example, the first rotor core group and the second rotor core group are assembled in sequence.

[0057] When assembling two rotor core groups 100 by the inclined-stage rotor assembly tool, the setting position of the positioning column 1 is fixed. 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. 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; then the turntable 2 is rotated so that the first keyway 1101 along the first clockwise direction on the rotor core 110 is located directly above the positioning key 11 and directly opposite to the positioning key 11. At this time, the rotor core 110 is axially slid downward, so that the first keyway 1101 along the first clockwise direction on the rotor core 110 can be plugged and positioned with the positioning key 11 to complete 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 on the turntable 2, so that the elastic telescopic positioning member 3 of the first elastic telescopic positioning member group is inserted and positioned with the rotor core 110; then the turntable 2 is rotated, so that the second keyway 1101 on the rotor core 110 along the first clockwise direction is located directly above the positioning key 11 and directly opposite to the positioning key 11, and at this time, the rotor core 110 is axially slid downward, so that the second keyway 1101 on the rotor core 110 along the first clockwise direction is inserted and positioned with the positioning key 11, so as to complete the relative positioning of the second rotor core 110 and the positioning column 1. And so on, until the multiple rotor cores 110 of the first rotor core group are assembled on the positioning column 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. The first rotor core 110 of the second rotor core group is sleeved 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 located directly above the positioning key 11 and directly 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 to complete 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 inserted and positioned with the rotor core 110; then the turntable 2 is rotated, and the second keyway 1101 on the rotor core 110 along the third clockwise direction is located directly above the positioning key 11 and directly opposite to the positioning key 11. At this time, the rotor core 110 is axially slid downward, and the second keyway 1101 on the rotor core 110 along the third clockwise direction can be inserted and positioned with the positioning key 11 to complete the relative position of the second rotor core 110 and the positioning column 1. And so on, until the multiple rotor cores 110 of the second rotor core group are assembled on the positioning column 1. Among them, the first clockwise direction and the third clockwise direction are opposite clockwise directions.

[0059] Specifically, a plurality of key slots 1101 of each rotor core 110 are arranged to be spaced in sequence along the first clockwise direction around the central axis of the rotor core 110, so that the distribution positions of the plurality of key slots 1101 when the rotor core 110 faces upward can be symmetrical with the distribution positions of the plurality of key slots 1101 when the rotor core 110 faces upward with respect to 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 rotor core 110 faces upward with its reverse side, the plurality of key slots 1101 are spaced in sequence along the third clockwise direction. Therefore, when assembling the first rotor core group, each rotor core 110 of the first rotor core group is sleeved on the turntable 2 with its reverse side facing upward; when assembling the second rotor core group, each rotor core 110 of the second rotor core group is sleeved on the turntable 2 with its reverse side facing upward. Or, when assembling the first rotor core group, each rotor core 110 of the first rotor core group is sleeved on the turntable 2 with the reverse side facing upward; when assembling the second rotor core group, each rotor core 110 of the second rotor core group is sleeved on the turntable 2 with the front side facing upward. This makes the arrangement position and number of grooves on each rotor core 110 the same, and can effectively reduce the number of key slots 1101 on the rotor core 110. This can effectively reduce the production difficulty and production cost of the rotor core 110, and can also effectively reduce 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 along the axial direction, and are symmetrically distributed along the first symmetry line, and the first symmetry line intersects the central axis of the turntable 2 vertically. When the front side of the rotor core 110 faces upward, the position where the rotor core 110 is plugged and positioned with one group of elastic telescopic positioning members 3 is the same as the position where the rotor core 110 is plugged and positioned with the other elastic telescopic positioning member 3 when the back side of the rotor core 110 faces upward. The setting positions and setting numbers of the plug-in positioning positions on each rotor core 110 are the same, and the setting number of the plug-in positioning positions on the rotor core 110 can be effectively reduced. Therefore, 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 prior art, the inclined-stage rotor assembly device has a simple structure and is convenient for assembling inclined-stage rotors for small-batch trial production or small-scale production; 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 sleeved on the turntable 2, the central axis of the rotor core 110, the rotation centerline of the rotor core 110, the central axis in the turntable 2, the rotation centerline of the turntable 2, the central axis of the positioning column 1 and the rotation centerline 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 may be the same, or may gradually increase, or may gradually decrease, or may gradually change according to a set rule. Further, the spacing variation rule of the multiple key slots 1101 of the rotor core 110 that are sequentially spaced and distributed along the first clockwise direction around the central axis of the rotor core 110 corresponds to the variation rule 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 key slots 1101 of each rotor core 110 are sequentially spaced and distributed along the first clockwise direction around their own central axis. When the deflection angles of the multiple rotor cores 110 gradually increase, the multiple key slots 1101 of each rotor core 110 are sequentially spaced and distributed along the first clockwise direction around their own central axis, and the spacing distances correspondingly increase gradually. When the deflection angles of the multiple rotor cores 110 gradually decrease, the multiple key slots 1101 of each rotor core 110 are sequentially spaced and distributed along the first clockwise direction around their own central axis, and the spacing distances correspondingly decrease gradually.

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

[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 stepped rotor to complete the assembly of the shaft 5 and all the rotor cores 110.

[0067] Preferably, if Figure 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 circumferential 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 inserted 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 can be understood 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, Figure 1 , Figure 2 and Figure 4 As shown, the rotation positioning structure also includes a rotating cover 4 coaxially rotatably connected to the second end of the rotating disk 2 along the axial direction. The rotating cover 4 is provided with a pushing portion 41 arranged around the outer periphery of the rotating disk 2. The pushing portion 41 is provided with two communicating holes 411 spaced apart along the circumference of the rotating cover 4, and the two communicating holes 411 are arranged one by one with the two elastic telescopic positioning members 3 of each group of elastic telescopic positioning members. The elastic telescopic positioning members 3 in the second working state pass through the rotating disk 2 and the corresponding communicating holes 411 and are inserted and positioned with 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 part 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, and the two elastic telescopic positioning members 3 of the first elastic telescopic positioning member group are partially extended out of the corresponding connecting holes 411 under the action of their own elastic restoring force. The two elastic telescopic positioning members 3 of the first elastic telescopic positioning member group are in the second working state, and the two elastic telescopic positioning members 3 of the second elastic telescopic positioning member group are in the first working state, and 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 part 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, and the two elastic telescopic positioning members 3 of the second elastic telescopic positioning member group are partially extended out of the corresponding connecting holes 411 under the action of their own elastic restoring force. The two elastic telescopic positioning members 3 of the second elastic telescopic positioning member group are in the second working state, and the two elastic telescopic positioning members 3 of the first elastic telescopic positioning member group are in the first working state, and 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, if Figure 1 , Figure 2 and Figure 4 As shown, one of the connecting holes 411 is located in the middle area of ​​the pushing portion 41 along the circumferential direction, and the other connecting hole 411 is located outside one end of the pushing portion 41 along the circumferential direction. That is, the end surface of one end of the pushing portion 41 along the circumferential direction is part of the inner circumferential wall of the other connecting hole 411. Such an arrangement can effectively simplify the structure of the pushing portion 41 and reduce the difficulty of processing the pushing portion 41.

[0073] Alternatively, if Figure 1-3As shown, one of the turntable 2 and the turntable cover 4 is provided with a limit column 21, and the other is provided with an arc-shaped limit hole 42, and the limit column 21 is inserted into the arc-shaped limit hole 42. When the limit column 21 abuts against the first end of the arc-shaped limit 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 limit column 21 abuts against the second end of the arc-shaped limit 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 limit hole 42 is located on the central axis of the turntable 2. This arrangement is provided to limit the rotation range of the turntable cover 4, and it is convenient to quickly and efficiently adjust one group of elastic telescopic positioning members 3 to be in the first working state retracted into the inside of the turntable 2, and the other group of elastic telescopic positioning members 3 is in the second working state partially extending from the outer peripheral wall of the turntable 2. Thereby, the efficiency of assembling each rotor core 110 into a whole according to the required deflection angle law can be further improved.

[0074] In this embodiment, if Figure 1 and Figure 3 As shown, the rotating disk 2 is provided with the limiting column 21, and the rotating cover 4 is provided with the arc-shaped limiting hole 42. As an alternative, the rotating disk 2 can also be provided with the arc-shaped limiting hole 42, and the limiting column 21 can be provided on the rotating cover 4.

[0075] Further optionally, if Figure 1-3 As shown, the outer wall of the turntable 2 is provided with a limit block 22 and two limit surfaces 23. Along the circumference of the turntable 2, the limit block 22 is located between the two limit surfaces 23, and the limit block 22 is located in a connecting hole 411 in the middle area of ​​the pushing part 41 along the circumference. The two limit surfaces 23 are arranged one-to-one with the two ends of the pushing part 41 along the circumference and can abut. The circumferential angle between the two ends of the arc-shaped limit hole 42 along the circumference is a first circumferential angle. The circumferential angle between the two ends of the pushing part 41 along the circumference is a second circumferential angle. Along the circumference of the turntable 2, the circumferential angle between the two limit surfaces 23 is a third circumferential angle. The third circumferential angle is the sum of the first circumferential angle and the second circumferential angle. This can further enhance the effect of limiting the rotation range of the rotary cover 4; it can also prevent the turntable 2 from rotating at will.

[0076] Among them, Figure 1 As shown, the end of the elastic telescopic positioning member 3 that can extend out of the turntable 2 and the corresponding connecting 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 inside of the turntable 2, so as to improve the smoothness and efficiency of changing the working state of the elastic telescopic positioning member 3 by the pushing part 41.

[0077] Preferably, in this embodiment, if Figure 1As shown, the guide surface 311 is an arc 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 changing the working state of the elastic telescopic positioning member 3 through the pushing portion 41.

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

[0079] Among them, Figure 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 rotating cover 4, and the positioning protrusion 31 can be inserted and positioned with the positioning groove 1102 of the rotor core 110. This arrangement enables 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, Figure 1-3 As shown, the elastic member 32 is exemplified as a spring.

[0081] Preferably, if Figure 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 recorded 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, 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 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 rotate the turntable 2 so that the first first mark A1 of the A mark group along the second clockwise direction is directly opposite to the positioning key 11, and at this time, the first keyway 1101 on the rotor core 110 along the first clockwise direction is located directly above the positioning key 11 and is directly opposite to the positioning key 11, and at this time, the rotor core 110 is axially slid downward, so that the first keyway 1101 on the rotor core 110 along the first clockwise direction can be plugged and positioned with the positioning key 11, so as to complete 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 inserted 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 directly opposite to the positioning key 11, at this time, the second keyway 1101 on the rotor core 110 along the first clockwise direction is located directly above the positioning key 11 and directly opposite to the positioning key 11, and the rotor core 110 is axially slid downward, so that the second keyway 1101 on the rotor core 110 along the first clockwise direction can be inserted and positioned with the positioning key 11, so as to complete the relative position of the second rotor core 110 and the positioning column 1. And so on, until the multiple rotor cores 110 of the first rotor core group are assembled on the positioning column 1. It can be understood that in this process, the second clockwise direction and the first clockwise direction are the same 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. The first rotor core 110 of the second rotor core group is sleeved 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 directly opposite to the positioning key 11, and 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 is directly opposite to the positioning key 11, and the rotor core 110 is axially slid downward, so that the first keyway 1101 of the rotor core 110 along the third clockwise direction can be plugged and positioned with the positioning key 11, so as to complete 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 inserted 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 directly opposite to the positioning key 11, and 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 directly opposite to the positioning key 11, and the rotor core 110 is axially slid downward, so that the second keyway 1101 of the rotor core 110 along the third clockwise direction can be inserted and positioned with the positioning key 11, so as to complete the relative position of the second rotor core 110 and the positioning column 1. And so on, until the multiple rotor cores 110 of the second rotor core group are assembled on the positioning column 1. It can be understood that in this process, the second clockwise direction and the third clockwise direction are the same clockwise direction.

[0085] Two identification groups are symmetrically distributed and both are located at the second end of the rotating disk along the axial direction. The multiple first identifications of one identification group correspond to the multiple key slots 1101 when the rotor core 110 faces upward, and the multiple first identifications of the other identification group correspond to the multiple key slots 1101 when the rotor core 110 faces upward. In this way, the rotor cores 110 can be assembled into a whole quickly and accurately according to the required deflection angle rule.

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

[0087] In this embodiment, if Figure 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 and 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 and 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, the 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 as an example. Figure 3 As shown, it is exemplified by taking the first symmetry line L and the second symmetry line L as being co-linear.

[0089] Preferably, if Figure 1-3As shown, along the axial direction of the positioning column 1, a second mark 111 is provided on the end of the positioning key 11 close to the turntable 2. The turntable 2 is rotated so that each first mark on the turntable 2 can be directly opposite to the second mark 111. The accuracy and efficiency of the deflection angle of the positioning rotor core 110 can be further improved. In this embodiment, the second mark 111 is exemplarily set as a triangular mark. As an alternative, the second mark 111 can also be set as an arrow mark or a color mark.

[0090] Among them, Figure 4-7 As shown, the inclined-stage rotor further includes a rotating shaft 5, which can be coaxially rotated and plugged into the end of the positioning column 1 axially away from the rotating disk 2, and the rotating shaft 5 is provided with a connecting key 51 extending in the axial direction. The inclined-stage rotor assembly tool further includes a guide key 6, and along the axial direction of the positioning column 1, one end of the guide key 6 is detachably connected to the end of the positioning key 11 away from the rotating disk 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 groups 100 to be sleeved on the rotating shaft 5.

[0091] After both rotor core groups 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, and then the rotating shaft 5 is rotated so that the positioning key 11 and the connecting key 51 are facing each other. Then the guide key 6 is 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. Then the rotor core 110 assembled on the positioning column 1 is pushed to the rotating shaft 5. It can be understood that the key slots 1101 on each rotor core 110 that are key-connected with the positioning key 11 are now key-connected with the connecting key 51 on the rotating shaft 5. To complete the assembly of the inclined rotor. Therefore, such a setting can not only quickly and efficiently assemble the rotating shaft 5 and each rotor core 110, but also effectively prevent the deflection angle of any rotor core 110 from changing.

[0092] It can be understood that when one axial end of the rotating shaft 5 is inserted into the end of the positioning column 1 axially away from the rotating disk 2, the central axis of the rotating shaft 5 is colinear with the central axis of the positioning column 1. When the positioning key 11, the guide key 6 and the connecting key 51 form a continuous key, 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 in one-to-one correspondence.

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

[0094] In this embodiment, if Figure 4-7As shown, the exemplary arrangement of the first connecting groove 112 includes a first sub-groove 1121 and a second sub-groove 1122 that are connected, and a lap joint surface 1123 is formed at the connection point between 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 that are connected. 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. Along the axial direction of the positioning column 1 from the positioning key 11 to the connecting key 51, the first sub-block 611 overlaps the lap joint surface 1123. With such an arrangement, when the guide key 6 is assembled on the positioning key 11, the guide key 6 can be prevented from falling off. As an alternative, the first connecting groove 112 can also be recessed on one end surface of the positioning key 11 away from the turntable 2, and the first connecting block 61 is inserted into the first connecting groove 112 along the axial direction of the positioning column 1. The relative positions of the connecting key 51 and the guide key 6 can also be located.

[0095] Specifically, Figure 4-7 As shown, the other end of the guide key 6 is provided with a second connection groove 62, and the second connection groove 62 can be plugged and matched with the connection key 51. When the second connection groove 62 is plugged into one end of the connection key 51, the guide key 6 and the connection key 51 form a continuous key. In this embodiment, the second connection groove 62 is exemplarily set to be an arc groove, and the two ends of the connection key 51 along the length direction are arc-shaped. As an alternative, the second connection groove 62 is a rectangular groove, and the connection key 51 is rectangular.
