DETAILED DESCRIPTION

[0028] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0029] In the present disclosure, unless otherwise stated, the directional words used, such as "inside" and "outside", refer to the inside and outside of the contour of each component itself. The terms "first" and "second" are used to distinguish one element from another element and do not have order or importance. In addition, when the following description refers to the drawings, the same reference numerals in different drawings represent the same or similar elements, and this disclosure will not repeat them.

[0030] According to some embodiments of the present disclosure, a stator and a housing assembly tool is provided, referring to Figures 1 to 4 As shown in the figure, the assembly tool includes: a base 1; a mounting platform 2, which is used to mount the stator 10 and is swingably arranged on the base 1; and a correction structure 3, which is arranged on the base 1 and is configured to drive the mounting platform 2 to swing relative to the base 1, so that the central axis of the stator 10 on the mounting platform 2 coincides with the preset axis.

[0031] Through the above technical scheme, in the assembly tool for the stator 10 and the shell provided in the present invention, when the stator 10 and the shell are assembled, the stator 10 can be installed on the mounting table 2, and then the correction structure 3 can be used to drive the mounting table 2 to swing, thereby driving the stator 10 on the mounting table 2 to swing, so that the central axis of the stator 10 coincides with the preset axis, thereby, the correction of the central axis of the stator 10 can be achieved, and then the central axis of the shell is set to coincide with the preset axis, and then the stator 10 and the shell are assembled. At this time, the concentricity or coaxiality of the shell and the stator 10 is good, therefore, scratches during assembly of the two can be avoided, that is, the technical problem that the stator 10 and the shell are easily scratched when assembled due to the central axis of the stator 10 having a certain verticality can be solved.

[0032] It should be noted that the mounting platform 2 may have an initial position, in which the central axis of the mounting platform 2 coincides with the preset axis, so that when the mounting platform 2 swings, the central axis of the stator 10 can be swung to coincide with the preset axis. Here, the present disclosure does not limit the specific structure of the deviation correction structure 3, which will be described in detail in the following embodiments.

[0033] In some embodiments of the present disclosure, reference Figures 1 to 4As shown in , the mounting platform 2 may have a through hole 21 for communicating with the stator 10, and the correction structure 3 extends out of the through hole 21 and is used to abut against the inner wall surface of the stator 10, so as to drive the mounting platform 2 to swing relative to the base 1 through the stator 10. The advantage of such a setting is that, on the one hand, the correction structure 3 can be set inside the mounting platform 2 to avoid interference between the correction structure 3 and the shell when the stator 10 is assembled with the shell, and on the other hand, the correction structure 3 can use the stator 10 to drive the mounting platform 2 to swing, thereby avoiding the correction structure 3 from being directly connected to the mounting platform 2, thereby simplifying the structure of the correction structure 3.

[0034] In some embodiments of the present disclosure, reference Figures 1 to 4 As shown in , the deviation correction structure 3 can be constructed as a three-jaw chuck, the central axis of the three-jaw chuck is constructed as a preset axis, and the claws 31 of the three-jaw chuck are used to abut against the inner wall surface of the stator 10. In this way, by utilizing the self-positioning property of the three-jaw chuck, when the three claws 31 are all in contact with the inner wall surface of the stator 10, that is, when the three-jaw chuck clamps the stator 10 from the inner side of the stator 10, the central axis of the stator 10 can be made to coincide with the central axis of the three-jaw chuck. In this way, the central axis of the stator 10 can be automatically corrected by the three-jaw chuck, and there is no need to measure the verticality of the central axis of the stator 10. Thus, the deviation correction steps can be simplified and the deviation correction efficiency can be improved. Here, in the process that the three claws 31 are all in contact with the inner wall surface of the stator 10, the three-jaw chuck can drive the mounting table 2 to swing through the stator 10.

[0035] It should be noted that the structure and working principle of the three-jaw chuck in the present disclosure are well known to those skilled in the art and will not be elaborated herein. The jaw 31 can move itself by driving a motor.

[0036] In other embodiments of the present disclosure, the correction structure 3 may also include a controller, a measuring member and a correction member, wherein the measuring member is used to measure the verticality of the central axis of the stator 10, and the correction member is used to drive the mounting table 2 to swing. The controller may drive the correction member to move according to the measuring member, so that the central axis of the stator 10 on the mounting table 2 coincides with the preset axis, and thus, such a setting may also realize the correction of the central axis of the stator 10. Here, the present disclosure only takes the correction structure 3 as a three-jaw chuck as an example for exemplary introduction.

[0037] In some embodiments, reference Figure 3 and Figure 4 As shown in , the jaw 31 has an arc-shaped mating surface 311, and the mating surface 311 is used to fit the inner wall surface of the stator 10. In this way, the correction accuracy of the three-jaw chuck can be improved by using the fit between the mating surface 311 and the inner wall surface of the stator 10.

[0038] In some embodiments of the present disclosure, reference Figure 1 and Figure 3 As shown in , a plurality of elastic members 4 may be provided between the mounting platform 2 and the base 1, and the plurality of elastic members 4 are arranged around a preset axis and are arranged to allow the mounting platform 2 to swing relative to the base 1. In this way, on the one hand, the plurality of elastic members 4 can support the mounting platform 2 on the base 1, and on the other hand, the mounting platform 2 can swing relative to the base 1 through the deformation of the elastic members 4, and the structure is simple and easy to implement.

[0039] In some embodiments of the present disclosure, reference Figure 1 and Figure 3 As shown in , a threaded connector 5 may be connected between the mounting platform 2 and the base 1, and the elastic member 4 may be configured as a compression spring, which is sleeved on the threaded connector 5. In this way, the reliability of the elastic member 4 after installation may be improved, and the stability of the assembly tool may be improved. Of course, in other embodiments, the elastic member 4 may also be configured as an elastic rubber, which is connected between the mounting platform 2 and the base 1, so that the mounting platform 2 may also be swung relative to the base 1.

[0040] In some embodiments of the present disclosure, reference Figure 1 and Figure 3 As shown in , multiple pairs of first stop posts 61 and second stop posts 62 arranged around a preset axis can be provided between the mounting platform 2 and the base 1. The mounting platform 2 is provided with a first stop post 61, and the base 1 is provided with a second stop post 62. When the mounting platform 2 swings to the maximum swing angle relative to the base 1, the corresponding first stop post 61 abuts against the second stop post 62. At this time, the first stop post 61 and the second stop post 62 can limit the mounting platform 2 from continuing to swing. Thus, the first stop post 61 and the second stop post 62 can be used to limit the maximum swing angle of the mounting platform 2 to prevent the mounting platform 2 from swinging excessively. Here, multiple pairs of first stop posts 61 and second stop posts 62 can limit the maximum swing angle of the mounting platform 2 in multiple directions.

[0041] In some embodiments of the present disclosure, a limiting structure may be provided on the mounting platform 2, and the limiting structure is used to limit the stator 10 from rotating around its own central axis relative to the mounting platform 2. In this way, the limiting structure can be used to limit the circumferential rotation of the stator 10, preventing the stator 10 from rotating and thus affecting the assembly with the housing.

[0042] In some embodiments of the present disclosure, reference Figures 2 to 4As shown in , the mounting platform 2 may have a mounting surface 22 and a T-shaped slot 23, the mounting surface 22 is used to receive the stator 10, and the limiting structure includes a T-shaped block 7 that can be set in the T-shaped slot 23, the T-shaped block 7 includes a first block 71 and a second block 72 that are perpendicular to each other, the first block 71 extends in a direction parallel to the preset axis and extends out of the mounting surface 22, and the first block 71 is used to be inserted into the matching slot 101 of the stator 10. In this way, the T-shaped slot 23 can limit the movement of the T-shaped block 7 in the circumferential direction of the mounting platform 2, and when the first block 71 is inserted into the matching slot 101 of the stator 10, the T-shaped block 7 is used to realize the circumferential rotation limiting of the stator 10, and the structure is simple and easy to operate. Here, according to some embodiments, at least two T-shaped slots 23 may be formed on the mounting platform 2, and each T-shaped slot 23 is connected to a T-shaped block 7, thereby improving the limiting effect of the limiting structure.

[0043] In some embodiments of the present disclosure, reference Figure 1 and Figure 3 As shown in , the preset axis extends along the first direction, the base 1 may include a first sub-seat 11 and a second sub-seat 12, the first sub-seat 11 is slidably connected to the second sub-seat 12 along the second direction, the first direction and the second direction are perpendicular to each other, and the mounting platform 2 is swingably arranged on the first sub-seat 11. In this way, by adjusting the position of the first sub-seat 11 in the second direction, the position of the central axis of the stator 10 on the mounting platform 2 in the second direction can be adjusted, thereby facilitating the coincidence of the preset axis with the central axis of the housing.

[0044] In some embodiments of the present disclosure, reference Figure 1 and Figure 3 As shown in , the base 1 may include a third sub-seat 13, the second sub-seat 12 is slidably connected to the third sub-seat 13 along the third direction, and the first direction, the second direction and the third direction are perpendicular to each other. In this way, by adjusting the position of the second sub-seat 12 in the third direction, the position of the central axis of the stator 10 on the mounting platform 2 in the third direction can be adjusted, thereby, in combination with the movement of the first sub-seat 11 in the second direction, the coincidence of the preset axis and the central axis of the housing can be achieved.

[0045] In some embodiments of the present disclosure, reference Figures 1 to 4 As shown in , the mounting platform 2 may include a first sub-platform 24 and a second sub-platform 25, wherein the first sub-platform 24 is swingably disposed on the base 1, and the second sub-platform 25 is used to mount the stator 10, wherein the second sub-platform 25 is rotatably disposed on the first sub-platform 24 around its own central axis. Here, for the dual-motor structure, the circumferential position of the three-phase lead wires 102 of the stator 10 in each motor is different, therefore, by rotating the second sub-platform 25, the circumferential position of the three-phase lead wires 102 of the stator 10 can be adjusted, thereby improving the adaptability of the assembly tooling.

[0046] In some embodiments of the present disclosure, reference Figures 1 to 4 As shown in , the base 1 may be provided with a driving structure 8, and the first sub-stage 24 is provided with an opening slot 241. The driving structure 8 is connected to the second sub-stage 25 through the opening slot 241, and is used to selectively drive the second sub-stage 25 to rotate. Here, the driving structure 8 and the second sub-stage 25 may be connected through the opening slot 241, and the second sub-stage 25 may be automatically rotated by the driving structure 8.

[0047] In some embodiments, reference Figures 1 to 4 As shown in , the driving structure 8 may include a telescopic cylinder 81 and a connecting arm 82. The telescopic cylinder 81 has a telescopic rod 811. The telescopic rod 811 may be perpendicular to the preset axis. The hinge axis of the telescopic rod 811 and the connecting arm 82 may be parallel to the preset axis. The connecting arm 82 is connected to the second sub-platform 25. In this way, the telescopic rod 811 can be extended and retracted to drive the connecting arm 82 to rotate around the hinge axis, thereby driving the second sub-platform 25 to rotate. The structure is simple and easy to operate.

[0048] Next, the present disclosure will provide a detailed introduction to the use of the assembly tooling in combination with the above specific implementations. Figures 1 to 4 As shown in , first, place the stator 10 on the mounting surface 22 of the mounting table 2, and make the matching groove 101 of the stator 10 plug into the T-shaped block 7. At this time, the three-jaw chuck partially extends into the stator 10, and then, each claw 31 gradually approaches and abuts against the inner wall surface of the stator 10. In this process, the three-jaw chuck drives the mounting table 2 to swing through the stator 10 to achieve automatic deviation correction of the central axis of the stator 10. When the matching surface 311 of each claw 31 is in contact with the inner wall surface of the stator 10, the central axis of the stator 10 coincides with the preset axis. Afterwards, the position of the preset axis can be adjusted by sliding the first sub-seat 11 and the second sub-seat 12, so that the preset axis coincides with the central axis of the shell. In this way, when the stator 10 and the shell are assembled, the two can be prevented from scratching each other.
