Without further limitation, the element defined by the statement "including one..." does not exclude the existence of additional identical elements in the process, method, article or device including the element.

[0035] Please refer toFigure 1 , Figure 2 and Figure 4 , Figure 1 is a perspective view of a motor assembly device provided by some embodiments of the present application, Figure 2 is a schematic view of a motor assembly device provided by some embodiments of the present application, Figure 4 is a schematic view of the motor assembly device clamping the rotor provided by some embodiments of the present application. The motor assembly device 100 may include a workbench 73, a fixed base 1, a clamping mechanism 2, an upper limit component 3, and a lower limit component 4.

[0036] The fixed base 1 is installed on the workbench 73. Among them, the fixed base 1 and the workbench 73 may be fixedly connected or detachably connected.

[0037] The clamping mechanism 2 is detachably connected to the fixed base 1 and is used for clamping the motor housing. Specifically, when the motor needs to be assembled, the clamping mechanism 2 is connected to the fixed base 1 so that the electronic housing can be in the pre-assembly position. Among them, when different motors need to be assembled, the clamping mechanism 2 can be replaced so that the replaced clamping mechanism 2 can be adapted to the motor to be assembled.

[0038] Exemplarily, the clamping mechanism 2 and the fixed base 1 can be detachably connected by means such as snap connection, threaded connection, magnetic attraction connection, etc.

[0039] The clamping mechanism 2 may have a mounting hole 211. The fixed base 1 may have a positioning hole 11, and the mounting hole 211 is directly opposite to the positioning hole 11. Specifically, the central axes of the mounting hole 211 and the positioning hole 11 coincide. When the clamping mechanism 2 is used to clamp the motor housing, the motor housing can be located at the mounting hole 211.

[0040] The upper limit component 3 may include an upper limit rod 31 and a first driving mechanism 32. The first driving mechanism 32 is used to drive the upper limit rod 31 to move in a direction close to or away from the fixed base 1. Specifically, it may be that the first driving mechanism 32 is used to drive the entire upper limit rod 31 to move in a direction close to or away from the fixed base 1, or it may be that the first driving mechanism 32 is used to drive a part of the upper limit rod 31 to move in a direction close to or away from the fixed base 1. Among them, the moving direction of the upper limit rod 31 may be parallel to the height direction of the motor assembly device 100.

[0041] Exemplarily, the upper limit rod 31 can be a telescopic rod, and the first driving mechanism 32 can drive the upper limit rod 31 to expand and contract, so that the upper limit rod 31 can extend towards the fixed base 1 or contract away from the fixed base 1. Among them, the first driving mechanism 32 can drive the upper limit rod 31 to move by means of belt transmission. It should be noted that the first driving mechanism 32 can also drive the upper limit rod 31 to move in other ways, such as by means of gears, chain drives, etc., which will not be elaborated in this application.

[0042] The upper limit rod 31 can be directly opposite to the positioning hole 11. Specifically, in the height direction of the motor assembly device 100, the orthographic projection of the upper limit rod 31 on the plane where the positioning hole 11 is located is located within the positioning hole 11. Thus, the upper limit rod 31 can perform reverse positioning on the stator inside the motor housing, so that the central axis of the inner circle of the stator can coincide with the central axis of the upper limit rod 31.

[0043] The lower limit assembly 4 can include a lower limit rod 41 and a second driving mechanism 42. The lower limit rod 41 can pass through the positioning hole 11 and the mounting hole 211. The second driving mechanism 42 is used to drive the lower limit rod 41 to move towards or away from the fixed base 1. Specifically, it can be that the second driving mechanism 42 is used to drive the entire lower limit rod 41 to move towards or away from the fixed base 1, or it can be that the second driving mechanism 42 is used to drive a part of the lower limit rod 41 to move towards or away from the fixed base 1. Among them, the moving direction of the lower limit rod 41 can be parallel to the height direction of the motor assembly device 100.

[0044] Exemplarily, the second driving mechanism 42 can drive the lower limit rod 41 to move by means of a worm and worm gear. It should be noted that the second driving mechanism 42 can also drive the upper limit rod 31 to move in other ways, which will not be elaborated in this application.

[0045] The lower limit rod 41 can be directly opposite to the upper limit rod 31. Specifically, in the height direction of the motor assembly device 100, the orthographic projection of the lower limit rod 41 on the plane where the mounting hole 211 is located is located within the positioning hole 11, and the upper limit rod 31 and the lower limit rod 41 can be used to clamp the rotor 200. Thus, the distance between the upper limit rod 31 and the lower limit rod 41 can be adjusted to adapt to rotors 200 of different lengths, which is beneficial to improving the versatility of the motor assembly device 100.

[0046] It should be noted that since the upper limit rod 31 can be a telescopic rod, the first driving mechanism 32 can drive the upper limit rod 31 to expand and contract, and the second driving mechanism 42 can be used to drive the lower limit rod 41 to move in a direction closer to or away from the fixed base 1. Then, when the upper limit rod 31 and the lower limit rod 41 clamp the rotor 200, the first driving mechanism 32, the upper limit rod 31, the lower limit rod 41, and the rotor 200 can form an integral body, so that the second driving mechanism 42 can drive this integral body to move in a direction closer to or away from the fixed base 1.

[0047] The following describes the assembly process of the motor.

[0048] First, place the motor housing with the stator on the clamping mechanism 2, and lock the motor housing by the clamping mechanism 2. Then fix the clamping mechanism 2 on the fixed base 1. The first driving mechanism 32 drives the upper limit rod 31 to move in a direction closer to the clamping mechanism 2, and the stator inside the motor housing is reversely positioned by the upper limit rod 31 to make the center axis of the inner circle of the stator coincide with that of the upper limit rod 31. Then, the second driving mechanism 42 drives the lower limit rod 41 to move in a direction closer to the upper limit rod 31. Manually place the rotor 200 on the lower limit rod 41, so that the upper limit rod 31 and the lower limit rod 41 clamp the rotor 200, and the upper limit rod 31 and the lower limit rod 41 are locked with the rotor 200. Finally, the upper limit rod 31, the rotor 200, and the lower limit rod 41 can be driven to move together, so that the rotor 200 is installed into the motor housing. Then tighten the locking screws, withdraw the upper limit rod 31, and then move the whole motor out, thus completing the assembly of the motor.

[0049] According to the motor assembly device 100 of the embodiment of the present application, by making the clamping mechanism 2 for clamping the motor housing detachably connected to the fixed base 1, and clamping the rotor 200 by the movable upper limit rod 31 and lower limit rod 41, when assembling different motors, the clamping mechanism 2 can be replaced, and the upper limit rod 31 and the lower limit rod 41 can adjust the spacing to clamp rotors 200 of different sizes, so that the motor assembly device 100 can be applicable to the assembly of different motors, which is beneficial to improving the versatility of the motor assembly device 100, and further beneficial to improving the R & D speed of the motor and reducing the R & D cost of the motor. In addition, the detachable clamping mechanism 2 is also convenient for replacement and maintenance, which is beneficial to improving the maintainability of the motor assembly device 100.

[0050] Please refer to Figure 2 and Figure 3 , Figure 3 which are partial schematic diagrams of the motor assembly device provided by some embodiments of the present application. In some embodiments, the motor assembly device 100 may further include a fine adjustment mechanism 5. The fine adjustment mechanism 5 can be connected to the fixed base 1 and is used to drive the fixed base 1 along the first direction (such as Figure 3in the X-axis direction shown) or the second direction (such as Figure 3 shown in the Y-axis direction). Specifically, under the drive of the fine-tuning mechanism 5, the position of the fixed base 1 can be adjusted, so that the position of the clamping mechanism 2 connected to the fixed base 1 can be driven to be adjusted, enabling the motor assembly device 100 to adapt to some dimensional errors of the motor housing and the axis changes of different types of motors during the R & D process, thus facilitating the improvement of the versatility of the motor assembly device 100.

[0051] The first direction can be orthogonal to the moving direction of the upper limit rod 31 and orthogonal to the second direction. Among them, "orthogonal" may not be completely orthogonal and there may be a certain reasonable deviation. That is to say, the plane where the moving direction of the fixed base 1 is located can intersect with the moving direction of the upper limit rod 31. Such a setting enables the fine-tuning mechanism 5 to adjust the fixed base 1 from other directions, avoiding interference of the movement of the fixed base 1 on the combined installation of the motor, thus facilitating the guarantee of the reliability of the combined installation of the motor.

[0052] Please continue to refer to Figure 2 and Figure 3 In some embodiments, the fixed base 1 may include a first fixed seat 12 and a second fixed seat 13. The first fixed seat 12 is slidably arranged on the workbench 73. The second fixed seat 13 is slidably arranged on the first fixed seat 12. The clamping mechanism 2 is detachably connected to the second fixed seat 13, so that the second fixed seat 13 can slide relative to the first fixed seat 12, thereby driving the clamping mechanism 2 to slide relative to the first fixed seat 12.

[0053] The fine-tuning mechanism 5 includes a first moving component 51 and a second moving component 52. The first moving component 51 can be used to drive the first fixed seat 12 to move in the first direction (such as Figure 3 shown in the X-axis direction), and the second moving component 52 can be used to drive the second fixed seat 13 to move in the second direction (such as Figure 3 shown in the Y-axis direction). Specifically, when there are dimensional errors in the motor housing, the dimensional errors can be eliminated by driving the first moving component 51 and the second moving component 52.

[0054] Thus, the first moving component 51 and the second moving component 52 can drive the first fixed seat 12 and the second fixed seat 13 to move, enabling the fine-tuning mechanism 5 to adjust the position of the clamping mechanism 2 installed on the fixed base 1, so as to better adapt to different types of motors.

[0055] Exemplarily, the first direction can be parallel to the length direction of the motor assembly device 100, and the second direction can be parallel to the width direction of the motor assembly device 100.

[0056] Please continue to refer toFigure 2 and Figure 3 In some embodiments, the first moving component 51 may include a first driving member 511 and a first sliding rail 512 extending in a first direction. The first fixed seat 12 may be slidably disposed on the first sliding rail 512. The first driving member 511 may be configured to drive the first fixed seat 12 to move. Specifically, sliders cooperating with the first sliding rail 512 extending in the first direction may be provided on both sides of the first fixed seat 12, and the first driving member 511 may drive the first fixed seat 12 to slide along the extending direction of the first sliding rail 512.

[0057] The second moving component 52 may include a second driving member 521 and a second sliding rail 522. The second sliding rail 522 may be disposed on a side of the first fixed seat 12 away from the first sliding rail 512. The second fixed seat 13 may be slidably disposed on the second sliding rail 522. The second driving member 521 may be configured to drive the second fixed seat 13 to move. Specifically, the first sliding rail 512 and the second sliding rail 522 are located on opposite sides of the first fixed seat 12, and sliders cooperating with the second sliding rail 522 extending in a second direction may be provided on both sides of the second fixed seat 13, and the second driving member 521 may drive the second fixed seat 13 to slide along the extending direction of the second sliding rail 522. Such a setting has a simple structure and high stability, which is beneficial to reducing the manufacturing cost of the motor assembly device 100.

[0058] Exemplarily, the first driving member 511 and the second driving member 521 may be driving screws.

[0059] Please continue to refer to Figure 2 and Figure 3 In some embodiments, the motor device may further include a plurality of guide posts 6. The plurality of guide posts 6 may be circumferentially spaced along the upper limit rod 31. Both the first support plate 33 and the second support plate 43 are slidably connected to the guide posts 6. The upper limit rod 31 is disposed on the first support plate 33, and the lower limit rod 41 is disposed on the second support plate 43. Specifically, the guide posts 6 pass through the first support plate 33 and the second support plate 43, and the first support plate 33 and the second support plate 43 may slide along the extending direction of the guide posts 6. The first support plate 33 may drive the upper limit rod 31 to move, and the second support plate 43 may drive the lower limit rod 41 to move. Wherein, when the upper limit rod 31 and the lower limit rod 41 clamp the rotor 200, the upper limit rod 31 and the lower limit rod 41 are connected to the rotor 200, and the first driving mechanism 32 may be disposed on the first support plate 33, so that the first driving mechanism 32, the upper limit rod 31, the rotor 200 and the lower limit rod 41 may be driven by the second driving mechanism 42 to slide relative to the guide posts 6. Thus, the upper limit rod 31 and the lower limit rod 41 can be guided through the guide posts 6, thereby ensuring the stability and reliability of the operation of the motor assembly device 100.

[0060] Exemplarily, the number of the guide posts 6 is four, and the four guide posts 6 are circumferentially spaced apart around the upper limit rod 31. Such a setting can ensure the stability of operation.

[0061] Please continue to refer to Figure 2 and Figure 3 In some embodiments, the clamping mechanism 2 includes a fixing plate 21 and a clamping member 22. The fixing plate 21 is detachably connected to the fixed base 1, and the clamping member 22 is detachably disposed on one side of the fixing plate 21 facing the upper limit rod 31 and is used for clamping the motor housing. Specifically, the positioning hole 11 is located on the fixing plate 21, and the clamping member 22 is disposed on the outer periphery of the positioning hole 11, and can clamp the motor housing disposed at the positioning hole 11. Among them, the clamping member 22 and the fixing plate 21 can be detachably connected by means of bolts, snap connections, etc. Thus, the structure of the clamping mechanism 2 can be made simple, which is conducive to reducing the manufacturing cost of the motor assembly device 100.

[0062] Exemplarily, the clamping member 22 can be a plurality of clamping blocks, and the plurality of clamping blocks can be adapted to the motor housing.

[0063] Please continue to refer to Figure 2 and Figure 3 In some embodiments, the clamping mechanism 2 further includes a plurality of handles 23. The plurality of handles 23 are disposed on one side of the fixing plate 21 facing the upper limit rod 31. By providing the handles 23, it is convenient to take the clamping mechanism 2.

[0064] Exemplarily, the handle 23 and the fixing plate 21 can be an integral part. Such a setting is conducive to improving the assembly efficiency of the motor assembly device 100.

[0065] Also exemplarily, the handle 23 and the fixing plate 21 are detachably connected. By providing the handle 23, it is convenient to take the clamping mechanism 2, and at the same time, it is also convenient to replace and repair the handle 23, which is conducive to reducing the manufacturing cost of the motor assembly device 100.

[0066] Exemplarily, the number of the handles 23 can be four, and the four handles 23 are disposed at the four corners of the fixing plate 21, so that the operator can save more effort when taking.

[0067] Please continue to refer to Figure 2 and Figure 3 In some embodiments, the motor assembly device 100 may further include a frame body 7. The frame body 7 may include an upper frame 71 and a lower frame 72. The upper frame 71 and the lower frame 72 are detachably connected, which is convenient for disassembling and assembling the motor assembly device 100 and is conducive to improving the convenience of use of the motor assembly device 100.

[0068] It should be noted that the upper frame 71 and the lower frame 72 can also be fixedly connected, and such a setting can ensure the stability of the operation of the motor assembly device 100.

[0069] The workbench 73, the fixed base 1, the clamping mechanism 2 and the lower limit component 4 are connected to the lower frame 72. The upper limit component 3 is connected to the upper frame 71. Thus, it is convenient to modularize the motor assembly device 100.

[0070] Please continue to refer to Figure 2 and Figure 3 , in some embodiments, the motor assembly device 100 may further include a first handwheel 721 and a second handwheel 722. The first handwheel 721 is disposed on the lower frame 72 and is in transmission connection with the first driving mechanism 32.
