[0026] Embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present application and should not be construed as a limitation of the present application.

[0027] Reference is made below to Figures 1 - 3 Describe a stator-rotor assembling device 10 for a motor according to an embodiment of the present application. The stator-rotor assembling device 10 includes a bench 11, a frame 12, a first pallet 13, and a second pallet 14. A base plate 111 adapted to support a motor housing is provided on the bench 11. The frame 12 is disposed on the bench 11. A slide rail 121 extending in the height direction is provided on the frame 12. The first pallet 13 is located on one side of the base plate 111 in the height direction and is slidably connected to the slide rail 121. A first limiting portion 131 is detachably provided on the first pallet 13. The first limiting portion 131 is selectively abutted against one end of the motor rotor. The second pallet 14 is located on the other side of the base plate 111 in the height direction and is slidably connected to the slide rail 121. A second limiting portion 141 is detachably provided on the second pallet 14. At least a part of the second limiting portion 141 passes through the base plate 111 and is selectively abutted against the other end of the motor rotor.

[0028] Currently, in the manufacture of motors, it is necessary to assemble the rotor into the stator. The stator-rotor assembly of motors is usually carried out manually with a simple tooling. Manual assembly cannot guarantee the positioning accuracy during the stator-rotor assembly, which affects the fit of the bearings and the mating surface. To this end, a stator-rotor assembly mechanism is usually used to assemble the stator and rotor of the motor. However, the existing stator-rotor assembly mechanisms can only assemble the stator and rotor of motors of the same model. When assembling motors of other models, additional stator-rotor assembly mechanisms need to be designed, which increases the cost.

[0029] As Figure 1 shown, specifically, the stator-rotor assembling device 10 includes a bench 11 and a frame 12. The bench 11 can provide a supporting function for the entire device. Support feet can be provided at the bottom of the bench 11 to ensure the overall stability of the stator-rotor assembling device 10 and prevent the stator-rotor assembling device 10 from sliding relative to the ground, improving the reliability of the stator-rotor assembling device 10. A base plate 111 can be provided on the bench 11. The base plate 111 and the bench 11 can form a detachable connection by bolts, screws, or the base plate 111 and the bench 11 can form a detachable connection by snap connection or plug connection. The base plate 111 can be used to support the motor housing. At the same time, the base plate 111 can also play a role in limiting the motor housing, ensuring that the motor can be stationary relative to the base plate 111 during the stator-rotor assembly, so as to facilitate the assembly of the motor rotor and the motor stator.

[0030] The frame 12 can be arranged on the bench 11. The frame 12 can be used to install other parts in the device. The frame 12 and the bench 11 can be fixed by bolts. And the frame 12 is provided with columns extending in the height direction. Slide rails 121 can be arranged on the columns. The first support plate 13 and the second support plate 14 can be connected to the slide rails 121 and slide relative to the slide rails 121. Further, the first support plate 13 can be located on one side of the base plate 111 in the height direction, and the second support plate 14 can be located on the other side of the base plate 111 in the height direction. Wherein, a first limiting portion 131 is detachably arranged on the first support plate 13. The first limiting portion 131 can selectively abut against one end of the motor rotor. It can be understood that the first support plate 13 and the first limiting portion 131 are detachably connected. For example, the first support plate 13 and the first limiting portion 131 can be detachably connected by bolts and screws. And the first limiting portion 131 can selectively abut against one end of the motor rotor.

[0031] It should be noted that the first support plate 13 can slide along the slide rail 121 towards the motor housing to abut the first limiting portion 131 against one end of the motor rotor. A second limiting portion 141 is detachably arranged on the second support plate 14. For example, the second support plate 14 and the second limiting portion 141 can be detachably connected by bolts and screws. At least a part of the second limiting portion 141 can penetrate through the base plate 111. And the end of the second limiting portion 141 can selectively abut against the other end of the motor rotor. Similarly, the second support plate 14 can slide along the slide rail 121 towards the motor housing to abut the end of the second limiting portion 141 against the other end of the motor rotor. Since the first support plate 13 and the first limiting portion 131 are detachably connected, and the second support plate 14 and the second limiting portion 141 are detachably connected. Therefore, when assembling the stator and rotor of different models of motors, only the corresponding first limiting portion 131 and second limiting portion 141 need to be replaced to meet the stator-rotor assembly of the motor. In a specific embodiment, sliders 132 are arranged on one side of the first support plate 13 and the second support plate 14 facing the slide rail 121. The sliders 132 can be slidably connected to the slide rail 121.

[0032] In the actual assembly process, first place the motor housing on the base plate 111. Move the first support plate 13 and the second support plate 14 to make the first limiting portion 131 and the second limiting portion 141 respectively abut against both ends of the motor rotor. Then move the first support plate 13 and the second support plate 14 again to move the motor rotor into the motor housing and assemble it with the stator. Then detach the first limiting portion 131 and the second limiting portion 141 from both ends of the motor rotor. Finally, remove the motor housing from the base plate 111 to complete the stator-rotor assembly of the motor.

[0033] In short, the first pallet 13 of the stator-rotor assembling device 10 in the embodiments of the present application is detachably connected to the first limiting portion 131, and the second pallet 14 is detachably connected to the second limiting portion 141. Therefore, when assembling the stator and rotor of motors of different models, only the corresponding first limiting portion 131 and second limiting portion 141 need to be replaced to meet the stator-rotor assembling of the motor. Moreover, by replacing the first limiting portion 131 and the second limiting portion 141, the stator-rotor assembling device 10 can also be applied to motor structures such as single motors and double motors, improving the compatibility of the stator-rotor assembling device 10 and reducing the cost of the device.

[0034] As Figure 1 and Figure 2 shown, in some embodiments of the present application, the first limiting portion 131 may include a first conversion plate 1311, a first fastener 1312, and a first ejector rod 1313. The first conversion plate 1311 can be detachably connected to the first pallet. In a specific embodiment, the first conversion plate 1311 and the first pallet may be connected by bolts. A first mounting hole penetrating in the height direction may be formed on the first conversion plate 1311. The first fastener 1312 may be disposed on the first conversion plate 1311, and the first fastener 1312 can be correspondingly disposed with the first mounting hole. The first ejector rod 1313 may penetrate through the first fastener 1312 and the first mounting hole. One end of the first top plate facing the base plate 111 can abut against one end of the motor rotor. Among them, the first ejector rod 1313 can be detachably connected to the first fastener 1312, so as to realize the replacement of the first ejector rod 1313. For example, when applied to single motors of different models, the first ejector rod 1313 can be replaced to meet the size of the motor rotor. When applied to double motors of different models, the entire first conversion plate 1311 can be replaced to meet the requirements.

[0035] In some embodiments of the present application, a first threaded portion may be formed on the outer peripheral wall of the first ejector rod 1313, and a second threaded portion may be formed on the inner peripheral wall of the first fastener 1312. The second threaded portion can be threadedly engaged with the first threaded portion to connect the first ejector rod 1313 to the first fastener 1312. A rocker portion 1314 may also be formed at one end of the first ejector rod 1313 away from the base plate 111. The rocker portion 1314 can rotate axially, thereby driving the entire first ejector rod 1313 to move in the height direction.

[0036] It can be understood that after the motor housing is placed on the substrate 111, the first tray and the second tray are moved to achieve the preliminary positioning of the motor rotor. After the second limiting portion 141 abuts against one end of the motor rotor, the operator can manually control the rocker portion 1314 to rotate the first ejector rod 1313 relative to the first fastener 1312, so as to drive the first ejector rod 1313 to move in the height direction until the first ejector rod 1313 abuts against the other end of the motor rotor, realizing the clamping of the motor rotor. Then, the first tray and the second tray are moved to move the motor rotor into the motor housing and assemble it with the motor stator.

[0037] As Figure 1 and Figure 2 shown, in some embodiments of the present application, the first limiting portion 131 further includes a guide post 1315. The guide post 1315 can be arranged on the side of the first conversion plate 1311 facing the substrate 111, and the guide post 1315 can extend in the height direction. The guide post 1315 can be connected to the first conversion plate 1311 or the first fastener 1312. The first ejector rod 1313 is disposed through the guide post 1315, and the first top plate and the guide post 1315 can have a clearance fit. The guide post 1315 can play a guiding role to ensure that when the operator controls the rocker portion 1314, the first ejector rod 1313 can move in the height direction along the guide post 1315, preventing the first ejector rod 1313 from shifting and ensuring the stability of the first ejector rod 1313 during movement.

[0038] As Figure 1 shown, in some embodiments of the present application, the second limiting portion 141 can include a second conversion plate 1411, a second fastener 1412 and a second ejector rod 1413. The second conversion plate 1411 can be detachably connected to the second tray 14. In a specific embodiment, the second conversion plate 1411 and the second tray can be connected by bolts. A second mounting hole penetrating in the height direction can be formed on the second conversion plate 1411. The second fastener 1412 can be arranged on the second conversion plate 1411, and the second fastener 1412 can be correspondingly arranged with the second mounting hole. The second ejector rod 1413 can be disposed through the second fastener 1412 and the second mounting hole, and one end of the second ejector rod 1413 facing the substrate 111 can abut against the other end of the motor rotor. Among them, the second ejector rod 1413 can be detachably connected to the second fastener 1412. When applied to single motors of different models, the first ejector rod 1313 and the second ejector rod 1413 are replaced to meet the size of the motor rotor. When applied to double motors of different models, the first conversion plate 1311 and the second conversion plate 1411 can be replaced to meet the requirements.

[0039] As Figure 1As shown, in some embodiments of the present application, the stator-rotor assembling device 10 may further include a driving device 15. The driving device 15 may be disposed on the frame 12, and the driving device 15 has a driving end 151 extending in the height direction. The driving end 151 may penetrate through the first tool-changing plate 1311 and the second tool-changing plate 1411, and the driving end 151 can be power-connected to the first tool-changing plate 1311 and the second tool-changing plate 1411. In a specific embodiment, the driving device 15 may be a motor, and the driving end 151 may be a connecting screw. The connecting screw and the first tool-changing plate 1311 and the second tool-changing plate 1411 may be threadedly connected. The motor can drive the connecting screw to rotate, so that the first tool-changing plate 1311 and the second tool-changing plate 1411 slide on the slide rail 121. The motor can be power-connected to a speed reduction mechanism to ensure that the rotation speed of the driving end 151 meets the requirements.

[0040] Furthermore, a bearing seat may be provided on the frame 12. The bearing seat may be sleeved on the outer end of the driving end 151 to ensure that the driving end 151 rotates more stably. The bearing seat can be connected to the frame 12 through a fixing plate. For example, the bearing seat and the fixing plate can be bolted together. The fixing plate can extend in the width direction, and both ends of the fixing plate in the width direction can be bolted to the frame 12. The bearing seat can be configured in multiple numbers, and using multiple bearing seats can further improve the stability of the driving end 151.

[0041] As Figure 3 shown, in some embodiments of the present application, the stator-rotor assembling device 10 may further include a tray assembly 112. The tray assembly 112 may be disposed on the substrate 111 and can move relative to the substrate 111. A support surface may be formed on the tray assembly 112. The support surface can be used to support the motor housing, and a support seat 1121 and a pressing plate 1122 may be provided on the support surface. The support seat 1121 can be attached to the bottom of the motor housing. In a specific embodiment, the support seat 1121 can be configured in multiple numbers, and multiple support seats 1121 can be spaced apart on the support surface. The support seat 1121 can prevent wear between the motor housing and the tray assembly 112. The support seat 1121 can be configured as a rubber part, which can reduce the vibration of the motor housing while increasing the friction between the motor housing and it, making the motor housing more stable during stator-rotor assembly. The pressing plate 1122 can play a role in fixing the motor housing. Further, the second ejector rod 1413 can selectively penetrate through the tray assembly 112 to ensure that the second ejector rod 1413 can penetrate through the motor housing and abut against the motor rotor.

[0042] As Figure 3As shown, in some embodiments of the present application, a roller track assembly 16 may further be provided between the substrate 111 and the tray assembly 112. The roller track assembly 16 can function to drive the tray assembly 112 to move on the substrate 111. For example, when the stator and rotor of the motor need to be assembled, the roller track assembly 16 can drive the tray assembly 112 to move to the outer end. When the motor housing is placed on the tray assembly 112, it then drives the tray assembly 112 to move directly above the substrate 111 to facilitate the assembly of the stator and rotor. Further, a limiting stop 113 may be provided on the substrate 111. The limiting stop 113 may be configured as multiple ones, and the multiple limiting stops 113 may be spaced apart on the substrate 111. Among them, the limiting stop 113 can abut against the tray assembly 112 to limit the movement of the tray assembly 112.
