Description

Technical Field

[0001] This invention relates to the field of motor housing assembly technology, and more particularly to a motor housing assembly apparatus. Background Art

[0002] With the rapid development of new energy vehicles, robotics, and other fields, motors, as core power components of modern industry, directly depend on the assembly precision of their internal structure and the sealing of their casing for performance and reliability. Motor components require assembly via manual labor or automated equipment.

[0003] In existing technologies, when assembling the motor housing and coil assembly using an automated assembly device, the motor housing is fixed in place by a positioning structure. Then, a robotic arm picks up the coil assembly and presses it into the motor housing, thus achieving automated assembly of the motor housing and coil assembly. When there is a misalignment between the assembly positions of the coil assembly and the motor housing, the motor housing needs to be rotated to adjust their alignment due to the weight of the coil assembly. However, since the positioning structures of traditional assembly devices are mostly fixed, it is difficult to rotate and position the motor housing. Summary of the Invention

[0004] The purpose of this invention is to provide an assembly device for a motor housing, which solves the technical problem that traditional assembly devices have difficulty in rotating and positioning the motor housing.

[0005] To achieve this object, the present invention adopts the following technical solutions: An assembly device for a motor housing includes a pressing base plate, an assembly assembly, and a rotary positioning mechanism.

[0009] Optionally, the pressing base plate is provided with a first through hole and a second through hole. One end of the first through hole communicates with the first rotating groove, and the other end of the first through hole communicates with the end of the pressing base plate away from the rotating disk.

A first hole is provided on the outer wall of the disc body, a second hole is provided on the first disc part opposite to the first hole, and a third hole is provided on the end of the second disc part near the first rotating groove. The first hole, the second hole and the third hole are interconnected.

[0010] Optionally, the boss is provided with a positioning hole, and the positioning assembly includes a positioning cylinder mounted on the rotary disk, and a positioning plate arranged in an inverted L shape is mounted on the telescopic rod of the positioning cylinder; The positioning plate is provided with a positioning post that is inserted into the positioning hole for positioning. The positioning plate and the positioning post are integrally formed. The positioning plate is used to position the end face of the boss that is away from the press-fit base plate.

[0011] Optionally, the assembly component includes a first assembly frame, a second assembly frame slidably connected to the first assembly frame and arranged perpendicularly to the first assembly frame, a third assembly frame slidably connected to the second assembly frame, and a clamping cylinder for clamping the coil assembly is installed on the third assembly frame, the clamping cylinder having three clamping claws distributed on it.

[0012] Optionally, it also includes a frame, on which the assembly component and the rotary positioning mechanism are both mounted, and on which a feeding component and a discharging component are also mounted; The feeding assembly is used to convey the coil assembly along the first direction, and the unloading assembly is used to convey the assembled motor housing and coil assembly along the first direction; the first direction, the second direction, and the third direction are perpendicular to each other.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention provides an assembly device for a motor housing. By having a rotating disk abut against the side wall of a boss, the rotating disk, driven by a rotary motor, directly transmits torque to the motor housing through the circumferential side wall of the boss, instead of relying on friction on the end face of the housing as in traditional devices. This structure avoids rotational slippage and ensures precise controllability of the housing's rotation angle. Through the positioning cooperation between the positioning component and the boss, the motor housing is mechanically locked after rotational adjustment, solving the technical defect of traditional fixed positioning structures that cannot dynamically adjust the angle during press-fitting. Since one end of the motor housing is embedded in the placement groove, its boss abuts against the end face of the press-fitting base plate, forming an axial limit; simultaneously, the rotating disk and positioning component circumferentially constrain the side wall of the boss, constituting radial and circumferential dual positioning, preventing displacement or overturning of the housing during press-fitting. The rotational connection between the rotating disk and the press-fitting base plate restricts rotational movement to the horizontal plane, preventing axial displacement due to external forces and ensuring repeatability of rotational positioning. By linking the rotary positioning mechanism with the assembly components, the angle adjustment of the motor housing is fully automated by the rotary motor and positioning components, requiring no manual intervention and adapting to the cycle time of high-speed automated production lines. Therefore, this invention solves the technical problem of traditional assembly devices' difficulty in rotary positioning of the motor housing. Attached Figure Description

[0020] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0021] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0023] This invention provides an assembly device for a motor housing, such as... Figures 1 to 10 As shown, it includes a press-fit base plate 10, an assembly assembly 20, and a rotary positioning mechanism 30. The assembly assembly 20 is used to drive the coil assembly 200 to move along a second direction and a third direction, and press it into the motor housing 100 on the press-fit base plate 10; the second direction and the third direction are perpendicular to each other. The rotary positioning mechanism 30 includes a rotary disk 31 rotatably connected to the pressing base plate 10. The rotary disk 31 is sleeved on the motor housing 100. A rotary motor 32 for driving the rotary disk 31 to rotate is installed on the rotary disk 31. The pressing base plate 10 is provided with a placement groove 11 for accommodating one end of the motor housing 100. The outer wall of the motor housing 100 is provided with a boss 101 that abuts against the end face of the pressing base plate 10. The rotating disk 31 abuts against the side wall of the boss 101 along the circumference of the motor housing 100, driving the motor housing 100 to rotate. A positioning component 35 is mounted on the rotating disk 31 for positioning and engaging with the boss 101. In this embodiment, the coil assembly 200 is a well-known structure in the art and will not be described further. The motor housing 100 and the boss 101 are integrally formed, and the motor housing 100 can be manually or robotically loaded onto the pressing base plate 10.

[0024] It should be noted that the motor housing assembly device provided by the present invention uses a rotating disk 31 that abuts against the side wall of the boss 101. Driven by a rotating motor 32, the rotating disk 31 directly transmits torque to the motor housing 100 through the circumferential side wall of the boss 101, instead of relying on friction on the end face of the housing as in traditional devices. This structure avoids rotational slippage and ensures precise controllability of the housing's rotation angle. Through the positioning component 35 and the boss 101, the motor housing 100 is mechanically locked after rotational adjustment, solving the technical defect of traditional fixed positioning structures that cannot dynamically adjust the angle during press-fitting. Since one end of the motor housing 100 is embedded in the placement groove 11, and its boss 101 abuts against the end face of the press-fitting base plate 10, axial limiting is formed; simultaneously, the rotating disk 31 and the positioning component 35 provide circumferential constraint on the side wall of the boss 101, constituting both radial and circumferential positioning, preventing displacement or overturning of the housing during press-fitting. By rotating the rotary disk 31 and pressing base plate 10, the rotational motion is confined to the horizontal plane, preventing axis deviation due to external forces and ensuring repeatability of rotational positioning. Through the linkage between the rotational positioning mechanism 30 and the assembly component 20, the angle adjustment of the motor housing 100 is fully automated by the rotary motor 32 and positioning component 35, requiring no manual intervention and adapting to the pace of high-speed automated production lines. Therefore, this invention solves the technical problem of traditional assembly devices' difficulty in performing rotational positioning of the motor housing 100.

[0025] like Figures 1 to 5 As shown, an arc-shaped rack 33 is fixedly connected to the rotating disk 31 and is disposed opposite to the positioning component 35. An active gear 34 that meshes with the arc-shaped rack 33 is mounted on the output shaft of the rotary motor 32. The arc radius of the arc-shaped rack 33 is the same as the radius of the circle of the rotating disk 31, and the inner diameter of the circle of the rotating disk 31 is larger than the inner diameter of the circle of the placement groove 11. In this embodiment, the arc-shaped rack 33 is welded and fixed to the rotating disk 31.

[0026] It should be noted that, since the radius of the arc of the rack 33 is the same as the radius of the circle of the rotating disk 31, the curve of the rack 33 perfectly matches the shape of the disk body 311. This ensures that the rotary motor 32 drives the rotating disk 31 to rotate stably through the meshing transmission of the drive gear 34 and the rack 33, ensuring that the motor housing 100 maintains a precise angle and position during rotation, avoiding rotational deviations caused by structural looseness or inaccurate positioning. Through the transmission cooperation of the drive gear 34 and the rack 33, high-torque rotation can be achieved in a compact layout, avoiding the slippage phenomenon of traditional chains or belts.

[0027] like Figures 1 to 10 As shown, the rotating disk 31 includes a disk body 311 arranged in a circular shape, and a first disk portion 312 for abutting against the boss 101 is provided on the inner side of the disk body 311. The disc body 311 has a second disc portion 313 arranged in a ring shape at one end near the pressing base plate 10. The pressing base plate 10 has a first rotating groove 12 corresponding to the second disc portion 313, and the second disc portion 313 is rotatably connected to the first rotating groove 12.

[0028] It should be noted that, since the disc body 311 is circularly arranged, its inner diameter is larger than the outer diameter of the motor housing 100, providing clearance for the rotation of the boss 101. The second disc portion 313 is rotatably connected to the first rotating groove 12, allowing the rotating disc 31 to rotate on the press-fit base plate 10. The complete circular structure of the second disc portion 313 provides 360-degree uniform support, achieving uniform stress distribution and avoiding deformation under stress, as is common in traditional bearings.

[0029] like Figures 5 to 10 As shown, the disc body 311 is also provided with a third disc part 314 in an arc shape at one end near the pressing base plate 10. The pressing base plate 10 is provided with a second rotating groove 13 corresponding to the third disc part 314. The third disc part 314 is rotatably connected in the second rotating groove 13. The second rotating groove 13 is spaced apart from the first rotating groove 12. The radius of the second rotating groove 13 is larger than the radius of the first rotating groove 12, and the depth of the first rotating groove 12 along the third direction is greater than the depth of the second rotating groove 13 along the third direction. In this embodiment, the disk body 311, the first disk portion 312, the second disk portion 313, and the third disk portion 314 are all integrally formed structures. The number of third disk portions 314 is set to four, and the four third disk portions 314 are equally spaced on the end face of the disk body 311 near the pressing base plate.

[0030] It should be noted that the arrangement of the third disc 314 enables the rotating disk 31 to achieve dual rotational coordination, ensuring good stability of the rotating disk 31 during rotation and preventing rotational stagnation. This solves the technical problem of instability of the rotating disk 31 during high-speed rotation. The second disc 313 provides the main support, while the third disc 314 assists in preventing overturning, preventing severe offset or vibration of the rotating disk 31 during rotation and ensuring stability during assembly. The equidistant distribution of the four third discs 314 enhances the uniform force distribution on the rotating disk 31, further improving the reliability of the system.

[0031] like Figures 5 to 10 As shown, the press-fit base plate 10 is provided with a first through hole 14 and a second through hole 15. One end of the first through hole 14 is connected to the first rotating groove 12, and the other end of the first through hole 14 is connected to the end of the press-fit base plate 10 away from the rotating disk 31. The second through hole 15 is connected to the first rotating groove 12 and the second rotating groove 13 respectively. In this embodiment, the first through hole 14 and the second through hole 15 are arranged opposite to each other. A first hole 3111 is provided on the outer wall of the disk body 311, a second hole 3121 is provided on the first disk portion 312 opposite to the first hole 3111, and a third hole 3131 is provided on the end of the second disk portion 313 near the first rotating groove 12. The first hole 3111, the second hole 3121, and the third hole 3131 are interconnected. In this embodiment, the first hole 3111, the second hole 3121, and the third hole 3131 together form a T-shaped heat dissipation channel.

[0032] It should be noted that when the rotating disk 31 rotates on the pressing base plate 10 for a long time, it generates a large amount of heat. Since the first hole 3111, the second hole 3121, and the third hole 3131 together form a T-shaped heat dissipation channel, rapid heat dissipation can be achieved, preventing heat accumulation. This solves the technical problem of heat not easily dissipating in the first rotating groove 12 and the second rotating groove 13 after prolonged operation of the rotating disk 31. Through the interconnected arrangement of the heat dissipation channel, the first rotating groove 12, the second rotating groove 13, the first hole 3111, and the second hole 3121, a three-dimensional heat dissipation network is formed, which can better dissipate heat and prevent high-temperature deformation of the rotating disk 31 and the pressing base plate 10. This solves the technical problem of poor heat dissipation efficiency of the rotating disk 31 and the pressing base plate 10 after prolonged operation.

[0033] It should also be noted that since the first hole 3111 and the second hole 3121 are both located on the side of the rotating disk 31, and the third hole 3131 is located at the bottom of the rotating disk 31, it facilitates the rapid discharge of internal heat and also prevents external dust or debris from blocking the heat dissipation channel. In addition, when the second disk 313 is tightly fitted with the first rotating groove 12, negative pressure is easily generated in the first rotating groove 12, making it inconvenient for the rotating disk 31 to rotate. In order to solve the technical problem of negative pressure in the first rotating groove 12, the airflow in the first rotating groove 12 and the second rotating groove 13 is smoothly circulated through the heat dissipation channel, the first through hole 14 and the second through hole 15, thereby preventing negative pressure from being generated in the first rotating groove 12.

[0034] like Figure 6 and Figure 7 As shown, the boss 101 is provided with a positioning hole 102, and the positioning assembly 35 includes a positioning cylinder 351 mounted on the rotating disk 31. The telescopic rod of the positioning cylinder 351 is equipped with a positioning plate 352 arranged in an inverted L shape. The positioning plate 352 is provided with a positioning arc surface 3521 that abuts against the motor housing 100. The positioning plate 352 is provided with a positioning post 353 that is inserted into the positioning hole 102 for positioning. The positioning plate 352 and the positioning post 353 are integrally formed. The positioning plate 352 is used to position the end face of the boss 101 away from the press-fit base plate 10. By positioning the boss 101 axially with the positioning plate 352 and positioning the boss 101 radially with the positioning post 353, a dual positioning fit of the motor housing 100 is achieved. By using the boss 101 of the motor housing 100 itself for positioning fit, the structure of the positioning component 35 is simpler and has a dual positioning effect, solving the technical problem of the complex positioning structure of the traditional motor housing 100.

[0035] It should be noted that by providing a positioning hole 102 on the boss 101 of the motor housing 100, and inserting the positioning pin 353 into the positioning hole 102, the positioning assembly 35 can effectively fix the motor housing 100 onto the rotating disk 31. The rotating disk 31 will achieve precise rotation of the motor housing 100 as driven by the positioning cylinder 351, ensuring that it will not be displaced or tilted during the assembly process. Furthermore, when adjusting the position of the motor housing 100, the cylinder parameters of the positioning cylinder 351 can be adjusted so that the positioning arc surface 3521 does not abut against the outer wall of the motor housing 100, and the positioning pin 353 is inserted into the positioning hole 102, which still retains insertion allowance. The positioning component 35 can cooperate with the rotation of the rotating disk 31 to jointly drive the motor housing 100 to rotate, so that the motor housing 100 moves to the corresponding assembly position. Then, the positioning cylinder 351 continues to work, so that the positioning arc surface 3521 abuts against the outer wall of the motor housing 100, and the positioning pin 353 is inserted into the positioning hole 102. Therefore, the positioning component 35 not only has a positioning function, but can also work together with the rotating disk 31 to jointly drive the motor housing 100 to rotate, which can reduce the stress on the rotating disk 31 when adjusting the position of the motor housing 100.

[0036] It should also be noted that the power of the rotary motor 32 is mainly used to drive the rotary disk 31 to rotate, while the positioning cylinder 351 plays a key role in accurately positioning and constraining the movement of the motor housing 100. The relative arrangement of the rotary motor 32 and the positioning cylinder 351 helps to balance the forces and inertia generated during rotation, avoiding stress concentration in one direction. By distributing the weight of the rotary motor 32 and the positioning cylinder 351 on both sides of the device, the stress distribution on the rotary disk 31 can be effectively balanced. During the rotation of the motor housing 100, the positioning cylinder 351 can maintain the stability of the motor housing 100, preventing equipment vibration or inaccurate positioning caused by unbalanced forces from rotation. The relative arrangement of the rotary disk 31 and the positioning cylinder 351 makes the overall center of gravity of the system more concentrated, avoiding mechanical stress caused by excessive gravity on one side or uneven distribution. This arrangement helps to improve the accuracy and stability of equipment operation, especially during long-term automated operation, reducing the risk of mechanical fatigue and structural deformation.

[0037] like Figures 1 to 4 As shown, the assembly component 20 includes a first assembly frame 21, a second assembly frame 22 slidably connected to the first assembly frame 21 and arranged perpendicularly to the first assembly frame 21, a third assembly frame 23 slidably connected to the second assembly frame 22, and a clamping cylinder 24 for clamping the coil assembly 200 is installed on the third assembly frame 23. The clamping cylinder 24 has three clamping claws 25 distributed on it. The first assembly frame 21 is equipped with an assembly electric cylinder 26 for driving the second assembly frame 22 to move along the second direction, and the second assembly frame 22 is equipped with an assembly air cylinder 27 for driving the third assembly frame 23 to move along the third direction. In this embodiment, the assembly electric cylinder 26 and the assembly air cylinder 27 drive the clamping air cylinder 24 to move along the second and third directions, and the clamping air cylinder 24 drives the clamping claw 25 to move, so that the clamping claw 25 clamps or releases the coil assembly 200.

[0038] Specifically, to prevent the second assembly frame 22 from sliding during assembly, a clamping cylinder 28 is installed on the first assembly frame 21. A clamping block 29 for clamping the second assembly frame 22 is installed on the telescopic rod of the clamping cylinder 28. By driving the clamping cylinder 28 to move the clamping block 29 along a third direction, the clamping block 29 abuts against the second assembly frame 22, applying a continuous clamping force to the second assembly frame 22, thereby effectively preventing the second assembly frame 22 from sliding or shifting during assembly. This fixing mechanism is crucial for ensuring the assembly accuracy of the coil assembly 200 and the motor housing 100, reducing the probability of incorrect assembly or component deformation. Furthermore, the clamping force provided by the clamping block 29 can synergize with the clamping force provided by the pressurizing component 70, allowing the coil assembly 200 to be pressed more smoothly into the motor housing 100.

[0039] It should be noted that the assembly electric cylinder 26 on the first assembly frame 21 and the assembly air cylinder 27 on the second assembly frame 22 can precisely control the movement of the clamping air cylinder 24 along the second and third directions, ensuring that the coil assembly 200 remains efficient and stable during clamping and release. Since the clamping air cylinder 24 has three clamping claws 25, it can be flexibly adjusted according to different models and shapes of coil assemblies 200, enhancing the adaptability and flexibility of the device.

[0040] like Figures 1 to 4 As shown, it also includes a frame 40 with a frame structure, the assembly component 20 and the rotary positioning mechanism 30 are both mounted on the frame 40, and the loading component 50 and the unloading component 60 are also mounted on the frame 40. The feeding assembly 50 is used to convey the coil assembly 200 along the first direction, and the unloading assembly 60 is used to convey the assembled motor housing 100 and the coil assembly 200 along the first direction; the first direction, the second direction, and the third direction are perpendicular to each other.

[0041] It should be noted that since the feeding assembly 50, assembly assembly 20, and unloading assembly 60 mounted on the frame 40 are all arranged in mutually perpendicular directions, space can be utilized to the maximum extent, improving the efficiency of the entire equipment, while also facilitating maintenance and repair. Through the coordinated work of the feeding assembly 50 and the unloading assembly 60, an effective assembly line operation is formed, enabling the rapid and efficient assembly of the motor housing 100 and the coil assembly 200, thus improving production efficiency and reducing the production cycle.

[0042] like Figures 1 to 5 As shown, a pressurizing assembly 70 is installed on the frame 40. The pressurizing assembly 70 includes a pressurizing cylinder 71, and a pressurizing block 72 is fixedly installed between the telescopic rod of the pressurizing cylinder 71 and the press-fitting base plate 10. Several fixing blocks 73 are fixedly installed on the frame 40. A movable slide rail 74 that is slidably connected to the side wall of the pressurizing block 72 is fixedly connected to the fixing block 73. The pressurizing cylinder 71 is used to drive the press-fitting base plate 10, the pressurizing block 72, and the movable slide rail 74 to move synchronously in a third direction. In this embodiment, when the assembly assembly 20 presses the coil assembly 200 into the motor housing 100 on the press-fitting base plate 10, the pressurizing assembly 70 applies a force to the press-fitting base plate 10, so that the coil assembly 200 and the motor housing 100 can be pressed better.

[0043] It should be noted that the pressurizing cylinder 71 drives the pressurizing block 72, the pressing base plate 10, and the moving slide rail 74 to move synchronously in a third direction via its telescopic rod. This ensures the accuracy of the pressurizing assembly 70 when applying pressure, minimizes deviations, and improves the pressing accuracy between the coil assembly 200 and the motor housing 100, thereby ensuring the overall assembly quality of the motor. The pressurizing block 72 ensures that pressure is applied evenly to the motor housing 100, preventing damage or deformation caused by excessive local pressure, enhancing assembly stability, and ensuring a tight fit between the coil assembly 200 and the motor housing 100.

[0044] like Figures 1 to 3 As shown, the feeding assembly 50 includes a feeding base 51 and a feeding electric cylinder 52. The feeding base 51 supports the coil assembly 200 and is slidably connected to the frame 40. The feeding base 51 and the feeding electric cylinder 52 are respectively connected to the frame 40. The feeding electric cylinder 52 is arranged along a third direction, and the slider of the feeding electric cylinder 52 is fixedly connected to the feeding base 51. To prevent the coil assembly 200 from detaching during movement, a first limiting block 511 and a second limiting block 512 are installed on the feeding base 51. The first limiting block 511 abuts against the outer wall of the coil assembly 200, and the second limiting block 512 abuts against the inner wall of the coil assembly 200.

[0045] It should be noted that the feeding cylinder 52 drives the feeding seat 51 to move along a third direction, causing the feeding seat 51 to carry the coil assembly 200 closer to the assembly assembly 20, thereby loading the coil assembly 200. The feeding assembly 50 can effectively cooperate with the assembly assembly 20, the rotary positioning mechanism 30, and other structures, improving the automation level and overall work efficiency of the production line, and effectively reducing labor intensity and operational risks.

[0046] like Figures 1 to 3 As shown, the unloading assembly 60 includes an unloading electric cylinder 61 mounted on the frame 40 and arranged along a third direction. The unloading electric cylinder 61 has an unloading plate 62 mounted on its slider for pushing the assembled coil assembly 200 and motor housing 100 to move and unload. The unloading plate 62 has an unloading arc surface 621 for abutting against the outer wall of the motor housing 100. The frame 40 is provided with a feeding chute 41, and a feeding rack 63 is installed on the side of the frame 40 opposite to the feeding assembly 50. A plurality of feeding rollers 64 are rotatably connected to the feeding rack 63. In this embodiment, the feeding rollers 64 can be rolled by power provided by a motor, or they can be unpowered rollers. One end of the feeding rack 63 is at the same height as the end face of the frame 40, or one end of the feeding rack 63 is inclined, so that the assembled motor housing 100 and coil assembly 200 can be automatically fed along the feeding rollers 64 under their own weight.

[0047] It should be noted that when assembly component 20 places the assembled motor housing 100 and coil assembly 200 into the unloading chute 41, the unloading electric cylinder 61 drives the unloading plate 62 to move. The unloading plate 62 pushes the assembled motor housing 100 and coil assembly 200 onto the unloading roller 64, thus achieving automatic unloading. Through the coordinated action of the unloading electric cylinder 61, the unloading plate 62, the unloading chute 41, the unloading frame 63, and the unloading roller 64, the unloading component 60 achieves a stable, efficient, and safe automatic unloading process, which not only improves production efficiency but also enhances the stability and safety of the entire motor housing 100 assembly process.

[0048] Working principle: During operation, the feeding component 50 drives the coil component 200 to move along the first direction. The assembly cylinder 26 drives the clamping cylinder 24 to move along the second direction to the material picking position. The assembly cylinder 27 drives the clamping cylinder 24 to extend into the coil component 200. The clamping cylinder 24 drives the clamping claw 25 to extend and clamp the coil component 200, thus realizing the feeding operation of the coil component 200. The rotary motor 32 drives the drive gear 34 to rotate, which in turn moves the arc rack 33. Since the arc rack 33 is fixedly connected to the rotating disk 31, it drives the rotating disk 31 to rotate, causing the first disk 312 to abut against the boss 101. This causes the motor housing 100 to rotate, placing the motor housing 100 in the correct assembly position. Then, the positioning cylinder 351 drives the positioning plate 352 and the positioning post 353 to move synchronously. The positioning post 353 is inserted into the positioning hole 102. The positioning plate 352 positions the end face of the boss 101 away from the press-fit base plate 10, thus achieving axial and radial fixation of the motor housing 100. Next, the coil assembly 200 is moved to the assembly position, and the clamping cylinder 28 drives the clamping block 29 to move, so that the clamping block 29 clamps the second assembly frame 22. The assembly cylinder 27 drives the clamping cylinder 24 to move in the third direction, so that the coil assembly 200 is inserted into the motor housing 100. At the same time, the pressurizing component 70 applies pressure to the pressurizing block 72 through the pressurizing cylinder 71, so that the coil assembly 200 and the motor housing 100 are successfully assembled, and the assembly operation of the motor housing 100 is completed. After the coil assembly 200 and the motor housing 100 are assembled, the assembly assembly 20 places it in the unloading chute 41 on the frame 40. The unloading assembly 60 starts to work, and the unloading electric cylinder 61 drives the unloading plate 62 to move along the first direction, so that the assembled coil assembly 200 and the motor housing 100 are unloaded into the unloading roller 64, thus realizing the unloading operation of the assembled coil assembly 200 and the motor housing 100.
