[0033] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0034] Example 1

[0035] Reference Figures 1 to 9 As shown, the assembly device of the present invention includes a frame 5, a positioning frame 1 and a positioning member 2. The positioning frame 1 is arranged on the frame 5, and the positioning member 2 is arranged on the positioning frame 1. An assembly station is arranged on the positioning member 2, and a clamping station is arranged on the frame 5. The positioning frame 1 and the positioning member 2 cooperate so that the axis of the assembly station coincides with the axis of the clamping station.

[0036] The assembly device of the present application makes the axis of the assembly station coincide with the axis of the clamping station, so as to realize the normal assembly of the target assembly component and the source assembly component. Figure 1 and Figure 7As shown, the assembly device of the present application includes a frame 5, a positioning frame 1 and a positioning member 2, the positioning frame 1 is arranged on the frame 5, and the positioning member 2 is arranged on the positioning frame 1; an assembly station is arranged on the positioning member 2, and the assembly station is used to install a target assembly component, and the target assembly component is a motor housing; a clamping station is arranged on the frame 5, and the clamping station is used to clamp a source assembly component, and the source assembly component is a motor stator; the axis of the assembly station can be adjusted by the mutual positioning between the positioning frame 1 and the positioning member 2, so that the axis of the assembly station coincides with the axis of the clamping station. Since the motor stator is installed on the clamping station, the motor housing is installed on the assembly station, and The axis of the motor stator coincides with the clamping station, and the axis of the motor housing coincides with the assembly station. Preferably, the axis of the motor housing and the axis of the motor stator are both in the horizontal direction. Therefore, the axis of the motor housing can be adjusted by the mutual positioning of the positioning frame 1 and the positioning member 2, so that the axis of the motor housing is in the horizontal direction, and the two ends of the motor housing are self-centered, so that the axis of the motor housing and the axis of the motor stator coincide with each other, so that the motor stator can be assembled into the motor housing along the axial direction of the motor housing, so as to realize the normal assembly of the motor, reduce the coaxiality tolerance of the two motor stators assembled in the motor housing, and thus ensure the electrical performance of the motor. In addition, the assembly device of the present application preferably adopts a horizontal arrangement, that is, when the motor housing is placed on the frame 5, the axis of the motor housing is arranged in the horizontal direction, and the corresponding motor stator and the axis of the assembly mechanism 6 are both arranged in the horizontal direction, so as to optimize the structure of the assembly device and facilitate the assembly of the motor stator.

[0037] In one embodiment, a first positioning portion 3 is provided on the positioning frame 1, and a second positioning portion 4 is provided on the positioning member 2. The first positioning portion 3 cooperates with the second positioning portion 4 so that the axis of the assembly station coincides with the axis of the clamping station.

[0038] The present application realizes the axis adjustment of the motor housing by the cooperation of the first positioning portion 3 and the second positioning portion 4. Figure 4 As shown, the positioning frame 1 is provided with a first positioning portion 3, which is a V-shaped block with a V-shaped surface; the positioning member 2 is provided with a second positioning portion 4, which is a cylindrical outer edge surface; the cylindrical second positioning portion 4 cooperates with the V-shaped surface to achieve the self-centering function of the motor housing. Figure 4As shown, a mounting platform 17 is provided on the frame 5, and the positioning frame 1 includes a first positioning frame 18 and a second positioning frame 19, and the first positioning frame 18 and the second positioning frame 19 are respectively arranged at both ends of the mounting platform 17, and the first positioning frame 18 and the second positioning frame 19 are both provided with a V-shaped surface; the positioning member 2 includes a first positioning member 20 and a second positioning member 21, and the first positioning member 20 and the second positioning member 21 are respectively arranged at the axial ends of the motor housing, and the outer edges of the first positioning member 20 and the second positioning member 21 are both cylindrical; wherein, the V-shaped surface on the first positioning frame 18 is the same as the V-shaped surface of the second positioning frame 19, and is located at the same height in the vertical direction, and the two V-shaped surfaces are aligned along the axial direction of the motor stator. In addition, the first positioning member 20 is the same as the second positioning member 21; when the heated motor housing is placed on the frame 5, the motor The outer edge of the first positioning member 20 at one end of the motor housing contacts the V-shaped surface on the first positioning frame 18, and the outer edge of the second positioning member 21 at the other end of the motor housing contacts the V-shaped surface on the second positioning frame 19. Since the outer edges of the first positioning member 20 and the second positioning member 21 are both cylindrical, the cylindrical outer edges cooperate with the V-shaped surfaces so that the two ends of the motor housing are located on the same horizontal plane, and since the V-shaped surface on the first positioning frame 18 and the V-shaped surface of the second positioning frame 19 are aligned along the axial direction of the motor stator, therefore, with the cooperation of the positioning member 2 and the positioning frame 1, the axis of the assembly station and the axial direction of the clamping station coincide, so that the axis of the motor housing coincides with the axis of the motor stator, so that the motor stator can be assembled into the motor housing along the axial direction of the motor housing, thereby realizing normal assembly of the motor and ensuring the electrical performance of the motor. Since the motor housing is provided with connection holes for connecting to the end caps at both ends along its axial direction, the positioning member 2 is provided with connection holes that correspond one-to-one with the connection holes on the motor housing. Bolts passing through the connection holes on the positioning member 2 and the connection holes on the motor housing can connect the positioning member 2 to the motor housing, eliminating the need to provide separate connection holes on the motor housing for the positioning member 2. In addition, when the assembly device is vertical, that is, when the motor housing is placed on the frame 5, the axis of the motor housing is arranged in the vertical direction, and the cylindrical outer edge of the positioning member 2 on the motor housing can be abutted against the V-block along its radial direction through a corresponding mechanism.

[0039] In one embodiment, a first limiting surface 34 and a second limiting surface 35 are provided on the positioning frame 1 , and along the axial direction of the assembly station, the positioning member 2 is located between the first limiting surface 34 and the second limiting surface 35 .

[0040] The present application limits the motor housing and the positioning member 2 by the first limiting surface 34 and the second limiting surface 35, so as to facilitate the assembly of the motor stator into the motor housing. Figure 8As shown, a first limiting surface 34 is provided on the first positioning frame 18, and a second limiting surface 35 is provided on the second positioning frame 19. When the motor housing is placed on the V-shaped surface of the positioning frame 1 through the positioning member 2, the first positioning member 20, the motor housing and the second positioning member 21 are an integral structural member. Along the axial direction of the assembly station, that is, along the axial direction of the motor housing, the integral structural member is located between the first limiting surface 34 and the second limiting surface 35. Therefore, the first limiting surface 34 and the second limiting surface 35 can limit the axial displacement of the integral structural member along the motor housing, so that the motor stator can be assembled into the motor housing along the axial direction of the motor housing.

[0041] In one embodiment, the assembly station is used to install the target assembly component, the clamping station is used to clamp the source assembly component, and an assembly mechanism 6 is provided on the frame 5. The assembly mechanism 6 is respectively provided at both ends of the positioning frame 1, and the assembly mechanism 6 is used to assemble the source assembly component to the target assembly component.

[0042] The present application uses an assembly mechanism 6 to simultaneously assemble two motor stators into the one-piece motor housing of the dual motor. Specifically, the assembly station is used to install the target assembly component, and the clamping station is used to clamp the source assembly component. The assembly device includes a frame 5, and the frame 5 is provided with an assembly mechanism 6. The assembly mechanism 6 is used to assemble the source assembly component on the clamping station to the target assembly component on the assembly station, that is, to assemble the motor stator on the clamping station into the motor housing on the assembly station. Furthermore, the assembly device of the present application includes at least two assembly mechanisms 6. Since the application scenario of the present application is the assembly of dual motors with back-to-back one-piece housings, the present application preferably provides two assembly mechanisms 6, such as Figure 7 As shown, along the axial direction of the motor housing, two assembly mechanisms 6 are located at either end of the positioning frame 1. That is, the two assembly mechanisms 6 are located at either end of the motor housing. That is, along the axial direction of the motor housing, one assembly mechanism 6 is located at one end of the motor housing, and the other assembly mechanism 6 is located at the other end of the motor housing. Therefore, the assembly mechanisms 6 at both ends of the motor housing can simultaneously assemble the two motor stators located at both ends of the motor housing into the heated motor housing, allowing the assembly of the two stators to be completed before the motor housing cools and shrinks.

[0043] In one embodiment, a mounting portion 36 is provided on the positioning member 2 , and the mounting portion 36 forms an assembly station for mounting a target assembly component.

[0044] The mounting portion 36 on the positioning member 2 of the present application forms an assembly station. Specifically, Figure 4As shown, the positioning member 2 is provided with a mounting surface 37 and a mounting hole 38, and the mounting surface 37 and the mounting hole 38 form a mounting portion 36; two positioning members 2 are provided in the present application, and the two positioning members 2 are provided at both axial ends of the motor housing. Since the present application connects the motor housing and the positioning member 2 through the original connecting hole on the motor housing and the mounting hole 38 on the positioning member 2, the axial end face of the motor housing contacts the mounting surface to realize the positioning of the motor housing in the left and right directions, and the positioning of the motor housing in the up and down and front and back directions is realized by connecting the mounting hole 38 with the original connecting hole on the motor housing. Therefore, the mounting portion 36 determines the installation position of the motor housing, and the mounting portion 36 forms the assembly station of the motor housing.

[0045] In one embodiment, the assembly device further includes an operating member 7, a third positioning portion 8 is provided on the positioning member 2, and a fourth positioning portion 9 is provided on the positioning frame 1. The positioning member 2 and the positioning frame 1 are positioned by cooperation between the operating member 7, the third positioning portion 8 and the fourth positioning portion 9.

[0046] The present application realizes the quick-change function between the positioning member and the positioning frame by cooperating with the operating member 7, the third positioning portion 8 and the fourth positioning portion 9. Specifically, since the positioning member 2 is connected to the motor housing through the existing connection hole on the motor housing, when the motor housing needs to be placed on the positioning frame 1 on the frame 5, the positioning member 2 and the positioning frame 1 need to have the ability to quickly change. Therefore, Figure 4 and Figure 5 As shown, the assembly device includes an operating member 7, which is a positioning pin. The positioning member 2 is provided with a third positioning portion 8, and the positioning frame 1 is provided with a fourth positioning portion 9. The third positioning portion 8 and the fourth positioning portion 9 are both positioning holes. The third positioning portion 8 is defined as a first positioning hole, and the fourth positioning portion 9 is defined as a second positioning hole. When the motor housing is placed on the positioning frame 1 through the positioning member 2, the first positioning hole on the positioning member 2 is aligned with the second positioning hole on the positioning frame 1. The positioning function of the positioning member 2 and the positioning frame 1 can be achieved by directly inserting the positioning pin into the first positioning hole and the second positioning hole to limit the radial displacement of the positioning member 2 relative to the positioning frame 1 along the motor housing. Under the action of the first limiting surface 34, the second limiting surface 35 and the positioning pin, the integrated structure formed by the positioning member 2 and the motor housing can be limited on the positioning frame 1 to prevent the integrated structure from being displaced during the assembly process of the motor stator. In addition, when the motor stator is assembled into the motor housing, the positioning pin can be directly pulled out from the first positioning hole and the second positioning hole, and the assembled motor housing can be separated from the positioning frame 1, so as to realize the rapid assembly and rapid disassembly between the positioning member 2 and the positioning frame 1, thereby realizing the quick replacement function of the motor housing. Figure 6As shown, a snap-fit ​​mechanism 22 is provided on the positioning pin. The snap-fit ​​mechanism 22 is compressible along the radial direction of the positioning pin. The snap-fit ​​mechanism 22 protrudes from the circumferential surface of the positioning pin in a free state, so that the outline size formed by the snap-fit ​​mechanism 22 and the positioning pin is larger than the inner diameter of the first positioning hole and the second positioning hole. As a result, when the positioning pin is inserted into the first positioning hole and the second positioning hole, it is inconvenient for the positioning pin to be detached from the positioning member 2 and the positioning frame 1. The snap-fit ​​mechanism 22 adopts a snap-fit ​​ball. When the user pulls the positioning pin with force, the snap-fit ​​mechanism 22 is compressed along the radial direction of the positioning pin under the limitation of the inner wall of the first positioning hole or the inner wall of the second positioning hole, so that the outline size formed by the snap-fit ​​mechanism 22 and the positioning pin is smaller than the inner wall of the first positioning hole or the inner wall of the second positioning hole, which facilitates the detachment of the positioning pin from the first positioning hole and the second positioning hole, thereby realizing the quick-change function of the motor housing. A first positioning sleeve 23 may be provided on the positioning member 2 , a second positioning sleeve 24 may be provided on the positioning frame 1 , the first positioning hole may be provided on the first positioning sleeve 23 , and the second positioning hole may be provided on the second positioning sleeve 24 .

[0047] In one embodiment, the assembly mechanism 6 is slidably disposed on the frame 5 , and a through hole 10 is provided on the positioning member 2 . The assembly mechanism 6 assembles the source assembly component to the target assembly component through the through hole 10 .

[0048] The positioning member 2 of the present application is annular. Specifically, Figure 4 As shown, that is, the first positioning member 20 and the second positioning member 21 are both annular, and a through hole 10 is formed at the center of the annular first positioning member 20 and the second positioning member 21. The axis of the through hole 10 coincides with the axis of the motor housing. Since the motor stator needs to be installed in the motor housing along the axial direction of the motor housing, the assembly mechanism 6 clamps the motor stator and installs the motor stator through the through hole 10 in the motor housing. That is, one of the assembly mechanisms 6 clamps one of the motor stators through the through hole 10 on the first positioning member 20 to install the motor stator to one end of the motor housing. At the same time, the other assembly mechanism 6 clamps the other motor stator through the through hole 10 on the second positioning member 21 to install the motor stator to the other end of the motor housing.

[0049] In one embodiment, a transfer mechanism 11 is provided on the frame 5 . The transfer mechanism 11 includes a transfer portion 12 . The transfer portion 12 is slidably provided on the frame 5 . The transfer portion 12 is used to transfer the source assembly component to the assembly mechanism 6 .

[0050] The present application transfers the motor stator to the assembly mechanism 6 through the transfer mechanism 11. Specifically, the frame 5 is provided with a transfer mechanism 11, such as Figure 3As shown, the transfer mechanism 11 includes a first sliding portion 25, a second sliding portion 26 and a transfer portion 12. The motor stator is transferred by the cooperation of the first sliding portion 25, the second sliding portion 26 and the transfer portion 12. Further, the first sliding portion 25 is slidably arranged on the frame 5. Figure 1 and Figure 3 In the illustrated position, the first sliding portion 25 slides on the frame 5 in the vertical direction; the second sliding portion 26 is slidably disposed on the first sliding portion 25, and the second sliding portion 26 slides on the frame 5 in the front-to-back direction; the transfer portion 12 is disposed on the second sliding portion 26; therefore, the transfer portion 12 can, in cooperation with the first sliding portion 25 and the second sliding portion 26, have sliding freedom in the front-to-back and vertical directions, and thus the transfer portion 12 can be controlled so that the target assembly component on the transfer portion 12 moves to a corresponding position, that is, the motor stator on the transfer portion 12 moves to a corresponding position so that the motor stator can be clamped by the clamping portion 13 of the assembly mechanism 6. The movement of the first sliding portion 25 and the movement of the second sliding portion 26 can be controlled by a controller or by an operating handle, which converts its rotational motion into sliding motion of the first sliding portion 25 in the vertical direction and sliding motion of the second sliding portion 26 in the front-to-back direction through a mechanism such as a lead screw.

[0051] In one embodiment, the assembly mechanism 6 includes a clamping portion 13 and an abutting portion 14. The clamping portion 13 forms a clamping station for clamping the source assembly component and is used to assemble the source assembly component to the target assembly component. The abutting portion 14 is used to abut or separate from the axial end surface of the target assembly component. The assembly mechanism 6 also includes a fourth sliding portion 28. Both the clamping portion 13 and the abutting portion 14 are disposed on the fourth sliding portion 28. The abutting portion 14 is located at the outer edge of the clamping portion 13. The clamping portion 13 is rotatable about its axis.

[0052] The present application realizes the assembly of the motor stator through the clamping portion 13 of the assembly mechanism 6. Specifically, Figure 2As shown, the assembly mechanism 6 includes a third sliding portion 27 , a fourth sliding portion 28 and a clamping portion 13 , and the third sliding portion 27 , the fourth sliding portion 28 and the clamping portion 13 cooperate to achieve clamping and transfer of the motor stator on the transfer portion 12 . Furthermore, the third sliding portion 27 is slidably arranged on the frame 5, and the sliding direction of the third sliding portion 27 on the frame 5 is along the left-right direction; the fourth sliding portion 28 is slidably arranged on the third sliding portion 27, and the sliding direction of the fourth sliding portion 28 on the frame 5 is along the up-down direction; the clamping portion 13 is arranged on the fourth sliding portion 28; therefore, the clamping portion 13 can have the freedom of sliding in the left-right direction and the up-down direction under the cooperation of the third sliding portion 27 and the fourth sliding portion 28, and then the clamping portion 13 can be controlled so that the motor positioning on the transfer portion 12 is moved to the corresponding position, so as to facilitate the clamping of the motor stator by the assembly mechanism 6; the transfer portion 12 forms a clamping station for clamping the source assembly component, that is, the transfer portion 12 forms a clamping station for clamping the motor positioning. Among them, when the motor housing is placed on the positioning frame 1 through the positioning member 2, the axis of the motor housing and the axis of the clamping portion 13 are located in the same vertical plane. Therefore, after the clamping portion 13 clamps the motor stator on the transfer portion 12, the axis of the motor stator can be made to coincide with the axis of the motor housing by the sliding movement of the fourth sliding portion 28 in the up and down directions, and then the motor stator can be installed in the motor housing by the sliding movement of the third sliding portion 27 in the left and right directions. In addition, since the integrated dual motors have different diameter sizes, when motor housings of different diameter sizes are placed on the positioning frame 1 through the positioning member 2, the axis of the motor housing is located at different heights. Therefore, the axis of the transfer portion 12 can be adjusted by the sliding movement of the fourth sliding portion 28 in the up and down directions, so that the axis of the motor stator coincides with the axis of the motor housing, and then the motor stator can be installed in the motor housing by the sliding movement of the third sliding portion 27 in the left and right directions, thereby improving the versatility of the assembly device. Among them, Figure 2As shown, the clamping portion 13 includes a clamping base 29 and a plurality of clamping jaws 30, wherein three clamping jaws 30 are preferably provided, and the three clamping jaws 30 are slidably provided on the clamping base 29 along the radial direction of the clamping base 29, and the three clamping jaws 30 slide synchronously and are provided in parallel. When the three clamping jaws 30 of the clamping portion 13 are inserted into the inner cavity of the motor stator, the three clamping jaws 30 slide radially outward synchronously, so that the outer edges of the three clamping jaws 30 abut against the inner wall of the motor stator, and then the motor stator is clamped by the clamping jaws 30, and the three clamping jaws 30 form a clamping station for clamping the motor stator; when the three clamping jaws 30 of the clamping portion 13 slide radially inward, the outer edges of the three clamping jaws 30 are separated from the inner wall of the motor stator, and then the motor stator can be separated from the clamping jaws 30. In addition, since the positioning member 2 is connected to the motor housing through the existing connection hole on the motor housing, the positioning member 2 and the motor housing are set to be detachably connected. When motor housings of different diameters need to be installed on the positioning frame 1, the positioning member 2 of the corresponding size can be replaced according to the diameter size of the motor housing. Among them, the movement of the third sliding part 27 and the movement of the fourth sliding part 28 can be controlled by a controller, or by an operating handle. The operating handle converts its rotational movement into the sliding movement of the third sliding part 27 in the left and right directions and the sliding movement of the fourth sliding part 28 in the up and down directions through a mechanism such as a lead screw. The present application realizes the pressure maintaining operation during the assembly process of the motor stator through the abutment portion 14 of the assembly mechanism 6. Specifically, as Figure 2As shown, the assembly mechanism 6 also includes an abutment portion 14 and a fifth sliding portion 33, and the pressure-maintaining operation during the motor stator assembly process is achieved through the cooperation of the abutment portion 14 and the fifth sliding portion 33. Furthermore, the fifth sliding portion 33 is slidably arranged on the third sliding portion 27, and the sliding direction of the fifth sliding portion 33 is the same as the sliding direction of the third sliding portion 27. The sliding movement of the third sliding portion 27 is mainly used for the clamping portion 13 to quickly move toward the motor housing and install the motor stator into the motor housing when clamping the motor stator, and the sliding movement of the fifth sliding portion 33 is mainly used for the pressure-maintaining operation when the motor stator is installed in the motor housing. Furthermore, the fourth sliding portion 28 is slidably arranged on the fifth sliding portion 33, so that when the fifth sliding portion 33 performs a sliding movement, it can drive the abutment portion 14 on the fourth sliding portion 28 to slide in the left and right directions. The movement of the fifth sliding part 33 can be controlled by a controller, or by an operating handle, and the operating handle can convert its rotational movement into the sliding movement of the fifth sliding part 33 in the left and right directions through a mechanism such as a screw. In addition, since the fifth sliding part 33 needs to implement a pressure-maintaining operation, the screw mechanism corresponding to the fifth sliding part 33 adopts a T-shaped tooth. When the motor stator is installed in the motor housing, its axial length will increase under the heat radiation of the motor housing. The T-shaped tooth screw mechanism will not produce relative sliding when the axial length of the motor stator increases. Therefore, the T-shaped tooth screw mechanism can effectively maintain pressure on the installation of the motor stator and the motor housing. Furthermore, the clamping part 13 of the present application is rotatably arranged on the fourth sliding part 28. Specifically, as Figure 2 As shown, the fourth sliding portion 28 is provided with a rotating shaft 31 along the axis of the motor housing, and a rotating base 32 is rotatably provided on the rotating shaft 31. The clamping base 29 and the abutting portion 14 are both provided on the rotating base 32, and the abutting portion 14 is located at the outer edge of the clamping base 29. The rotating base 32 drives the clamping base 29 to rotate, and the clamping base 29 further drives the three clamping jaws 30 to rotate, so that the motor stator clamped by the clamping jaws 30 can be rotated to an angle corresponding to the motor housing, and the motor stator can be installed in the motor housing.

[0053] In one embodiment, a support and positioning mechanism 15 and a roller mechanism 16 are provided at the bottom of the frame 5 . The support and positioning mechanism 15 is used to adjust the distance between the frame 5 and the ground and to support the frame 5 .

[0054] This application can move the assembly device. Specifically, Figure 1As shown, the bottom of the rack 5 of the present application is provided with a roller mechanism 16, which allows the rack 5 to be moved via the roller mechanism 16, so as to facilitate the movement of the assembly device to the desired location, facilitating R&D, testing, and assembly. Furthermore, the bottom of the rack 5 is also provided with a support and positioning mechanism 15, which can be connected to the bottom of the rack 5 using a threaded connection or other means, so that the distance between the rack 5 and the ground can be adjusted via the support and positioning mechanism 15. When it is necessary to move the assembly device, the distance between the frame 5 and the ground is reduced by adjusting the support positioning mechanism 15 until the rollers on the frame 5 contact the ground and the bottom of the support positioning mechanism 15 is separated from the ground, and the user can push the assembly device to move to the required position; after the assembly device moves to the required position, the distance between the frame 5 and the ground bracket is increased by adjusting the support positioning mechanism 15 until the support positioning mechanism 15 contacts the ground and the rollers on the frame 5 are separated from the ground, and the frame 5 is supported by the support positioning mechanism 15 to avoid damage to the roller mechanism 16 caused by long-term support of the frame 5.

[0056] In another aspect, an assembly method is provided, such as Figure 9 As shown, Figure 9 A flow chart of the assembly method provided in an embodiment of the present application.

[0057] Assembly methods include:

[0058] S1, installing the source assembly component on the clamping station, and assembling the target assembly component and the positioning member 2 into an integrated structure, and heating the integrated structure.

[0059] The assembly method of the present application utilizes an assembly device to assemble a source assembly component with a target assembly component. Specifically, the source assembly component is a motor stator, and the target assembly component is a motor housing. During assembly, the motor housing is mounted in a clamping station. Furthermore, since the motor housing needs to be heated before the motor stator is installed, in order to address the problem of inconvenient assembly of the motor housing with the positioning members after heating, the present application assembles the motor housing with two positioning members before heating the motor housing, forming an integrated structure of the motor housing and the positioning members, and directly heats the integrated structure.

[0060] S2, placing the heated integrated structural component on the positioning frame 1 to place the target assembly component at the assembly station;

[0061] After the integrated structure of the motor housing and the positioning member is heated to the required temperature, the integrated structure is transferred to the positioning frame so that the motor housing can be placed on the assembly station.

[0062] S3, the positioning frame 1 and the positioning member 2 cooperate to make the axis of the assembly station coincide with the axis of the clamping station.

[0063] After the integrated structural component is transferred to the positioning frame, the axis of the motor housing and the axis of the motor stator are aligned through the contact and cooperation between the positioning frame and the positioning component.

[0064] S4, assembling the source assembly component on the clamping station into the target assembly component on the assembling station.

[0065] After the axis of the motor housing and the axis of the motor stator are aligned through the cooperation of the positioning frame and the positioning piece, the motor stator on the clamping station is installed into the motor housing on the assembly station along its axial direction to achieve normal assembly of the motor stator and the motor housing.
