Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, and in particular to a motor assembly device. Background Technology

[0002] As the core power component of rail transit equipment, the quality of traction motor maintenance directly affects the safety and stability of locomotive operation. The assembly of stator and rotor is a key process in the maintenance of traction motor, and the accuracy and efficiency of assembly are crucial to the overall maintenance process.

[0003] Currently, in the assembly of motor stators and rotors, the stator is typically clamped, moved, and placed using simple tooling. Due to the lack of a dedicated positioning and clamping mechanism, relative misalignment easily occurs between the stator and the work station, affecting the coaxiality of the stator and rotor assembly. Furthermore, the gripping and attitude adjustment of the rotor largely rely on manual labor in conjunction with overhead cranes or simple lifting tools, which not only makes it difficult to accurately control the rotor's spatial position but also results in low adjustment efficiency and high labor intensity. During the stator and rotor assembly stage, manual pushing or overhead crane lifting is mainly used to insert the rotor into the stator. This method cannot achieve uniform control of traction force, easily causing collision damage between the rotor and the inner wall of the stator, resulting in low safety and overall assembly efficiency.

[0004] Therefore, there is an urgent need for a specialized device that can achieve precise stator positioning and smooth and efficient assembly of the stator and rotor, in order to solve the problems of low assembly accuracy, high risk of damage, and insufficient operation efficiency in the existing technology.

[0046] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0047] like Figures 1-12 As shown, this embodiment provides a motor assembly device, which includes a support frame 1, a clamping mechanism 2, an adjustment mechanism 3, and a traction assembly mechanism 4. The clamping mechanism 2 is disposed on the support frame 1 and includes a first driving component 21, a first clamping component 22, and a second clamping component 23. The first driving component 21 can drive the first clamping component 22 and the second clamping component 23 to move. The first clamping component 22 is configured to clamp a fixed seat 200 for supporting the stator 100, and the second clamping component 23 is configured to clamp the stator 100. The adjustment mechanism 3 is disposed on the support frame 1 and includes a second driving component 31 and a gripping and releasing component 32. The second driving component 31 can drive the gripping and releasing component 32 to move, and the gripping and releasing component 32 is configured to grip and release the rotor 300. The traction assembly mechanism 4 is disposed on the support frame 1 and includes a third driving component 41 and an automatic traction component 42. The third driving component 41 can drive the automatic traction component 42 to extend into the stator 100, and the automatic traction component 42 is used to pull the rotor 300 into the stator 100.

[0048] In this embodiment, the clamping mechanism 2 is disposed on the support frame 1 and includes a first driving component 21, a first clamping component 22, and a second clamping component 23. The first driving component 21 can drive the first clamping component 22 and the second clamping component 23 to move. The first clamping component 22 is configured to clamp the fixed seat 200 for supporting the stator 100, and the second clamping component 23 is configured to clamp the stator 100, thereby achieving dual precise positioning of the stator 100 and the fixed seat 200, avoiding positioning errors caused by stator 100 offset during assembly, and solving the problem of unstable stator 100 positioning in the prior art. The attitude adjustment mechanism 3 is disposed on the support frame 1 and includes a second driving component 31 and a gripping and releasing component 32. The second driving component 31 can drive the gripping and releasing component 32 to move. The gripping and releasing component 32 is configured to... The rotor 300 is gripped and released, and the gripping and releasing component 32 is moved by the second drive component 31 to accurately grip and release the rotor 300 and flexibly adjust its posture, ensuring the coaxiality of the rotor 300 and the stator 100, thus solving the problem of the rotor 300 being difficult to accurately align with the stator 100 in the prior art; the traction assembly mechanism 4 is set on the support frame 1, including the third drive component 41 and the automatic traction component 42. The third drive component 41 can drive the automatic traction component 42 to extend into the stator 100. The automatic traction component 42 is used to pull the rotor 300 into the stator 100. The automatic traction component 42 is driven by the third drive component 41 to extend into the stator 100 for smooth traction, avoiding uneven traction force caused by manual or overhead crane pushing, and effectively reducing the risk of collision damage during the assembly of the stator 100 and the rotor 300. With the above settings, the motor assembly device of this embodiment can achieve automated connection of the entire assembly process through the coordinated action of the clamping mechanism 2, the attitude adjustment mechanism 3 and the traction assembly mechanism 4, reduce manual intervention, improve the accuracy and efficiency of the stator 100 and rotor 300 assembly, reduce labor intensity, and ensure the safety and reliability of the assembly process.

[0049] It should be noted that the first drive component 21 and the second drive component 31 in this embodiment include, but are not limited to, an XYZ three-axis linear module, a multi-joint robotic arm drive mechanism, or a combination mechanism of linear motor and rotary motor. Through the orthogonal arrangement between modules or the multi-degree-of-freedom linkage of the robotic arm, they can realize free movement of the first clamping component 22, the second clamping component 23, and the gripping and releasing component 32 in three-dimensional space.

[0050] The specific structure of the motor assembly device is described below:

[0051] Specifically, such as Figures 1-8 As shown, the first clamping assembly 22 includes a first clamping driver 221 and two first grippers 222. The first clamping driver 221 can drive the two opposing first grippers 222 to move toward each other to clamp the fixed seat 200, thereby achieving symmetrical clamping and stable fixation of the fixed seat 200 and improving the positioning accuracy of the fixed seat 200.

[0052] More specifically, in this embodiment, the first clamping driver 221 includes a cylinder, the output end of which is connected to the first gripper 222, enabling the first gripper 222 to move, thereby achieving rapid response and smooth operation of the first gripper 222 and improving clamping efficiency. When the two first grippers 222 move towards each other, they can clamp the fixed seat 200; when the two first grippers 222 move away from each other, they can release the fixed seat 200, thereby achieving rapid clamping and release of the fixed seat 200 and improving the continuity of loading and unloading operations. In other embodiments, the first clamping driver 221 includes an electric cylinder, the output end of which is connected to the first gripper 222, which can also achieve the above-mentioned functions. The specific structure of the first clamping driver 221 is not limited here.

[0053] Specifically, such as Figures 1-9 As shown, the second clamping assembly 23 includes a second clamping driver 231 and two second clamping jaws 232. The second clamping driver 231 can drive the two opposing second clamping jaws 232 to move toward each other or away from each other. The stator 100 is provided with two opposing and spaced-apart clamping portions 101. When the two second clamping jaws 232 move away from each other, the second clamping jaws 232 can extend into the lower part of the clamping portion 101 to support the stator 100. This not only enables the lower support and stable fixation of the stator 100, but also avoids the clamping force from directly acting on the stator 100 body and causing damage to the component.

[0054] More specifically, in this embodiment, the second clamping driver 231 includes a cylinder, the output end of which is connected to the second gripper 232. This cylinder drives the second gripper 232 to move, ensuring the smoothness and synchronization of its movement and improving the accuracy of clamping the stator 100. When the two second grippers 232 move away from each other, they can extend under the clamping part 101 to support and fix the stator 100. When the two second grippers 232 move closer to each other, they can disengage from the clamping part 101 to release the stator 100. In other embodiments, the second clamping driver 231 includes an electric cylinder, the output end of which is connected to the second gripper 232. This also achieves the above-mentioned function. The specific structure of the second clamping driver 231 is not limited here.

[0055] Specifically, such as Figures 1-10 As shown, the gripping and releasing assembly 32 includes a fixing part 321 and a plugging part 322. When the second driving assembly 31 drives the gripping and releasing assembly 32 to move closer to the clamping mechanism 2, the fixing part 321 can be sleeved on the rotating shaft of the rotor 300 to grip the rotor 300, and the plugging part 322 can be plugged into the rotor 300, thereby realizing dual positioning and stable gripping of the rotor 300 and improving the reliability of gripping the rotor 300.

[0056] More specifically, in this embodiment, the fixing part 321 includes a fixing rod, one end of which is provided with a through groove for the rotor 300 shaft to pass through, thereby achieving a precise fit between the fixing part 321 and the rotor 300 shaft and improving the coaxiality of the rotor 300 gripping. The insertion part 322 includes an insertion plate. When the second driving assembly 31 drives the fixing part 321 to move and fit onto the rotor 300 shaft, the insertion plate is inserted into the rotor 300, further enhancing the connection stability between the rotor 300 and the gripping and releasing assembly 32, preventing the rotor 300 from rotating circumferentially during the attitude adjustment process, and improving the attitude adjustment accuracy.

[0057] Specifically, such as Figures 1-11 As shown, the attitude adjustment mechanism 3 also includes an attitude adjustment component 34, which includes a rotating member 341, a first sliding member 342, and an adjustment driver 343. The rotating member 341 is rotatably connected to the output end of the second drive component 31, the first sliding member 342 is slidably connected to the rotating member 341, and the fixed part 321 is disposed on the first sliding member 342. One end of the adjustment driver 343 is rotatably connected to the output end of the second drive component 31, and the telescopic output end of the other end of the adjustment driver 343 is rotatably connected to the first sliding member 342. The adjustment driver 343 can drive the first sliding member 342 to rotate relative to the second drive component 31 to adjust the pitch angle of the fixed part 321, thereby ensuring that the end face of the rotor 300 is parallel to that of the stator 100 and avoiding assembly interference caused by the pitch deviation of the rotor 300.

[0058] More specifically, in this embodiment, the rotating component 341 includes a rotating frame, which is hinged to the output end of the second drive assembly 31, thereby enabling the rotating component 341 to rotate flexibly and improving the stability of the posture adjustment action. The first sliding component 342 includes an arc-shaped hanger, one end of which is slidably connected to the rotating frame, and the other end of which is provided with a fixing part 321, thereby providing a stable support carrier for the fixing part 321, while reserving installation space for the rotor 300, and avoiding interference of the arc-shaped hanger with the gripping and assembly of the rotor 300. The adjustment driver 343 includes a cylinder, one end of which is rotatably connected to the output end of the second drive assembly 31, and the telescopic output end of the other end of the cylinder is rotatably connected to the arc-shaped hanger. Through the telescopic movement of the telescopic output end of the cylinder, the rotating frame is driven to rotate relative to the support frame 1, thereby adjusting the pitch angle of the fixing part 321 on the arc-shaped hanger, thereby improving the accuracy of the pitch angle adjustment of the fixing part 321.

[0059] In other embodiments, the adjustment actuator 343 includes, but is not limited to, structures such as hydraulic cylinders or electric cylinders, and the specific structure of the adjustment actuator 343 is not limited here.

[0060] More specifically, the fixing part 321 is provided with a locking component 33 at the end away from the through slot. The locking component 33 is used to lock the rotor 300 to the fixing part 321, thereby realizing a secondary locking between the rotor 300 and the fixing part 321. The locking component 33 includes, but is not limited to, an elastic clamping structure, an electromagnetic adsorption structure, or a pin positioning structure, and those skilled in the art are clear about the specific working principle of the above structures, which will not be described in detail here.

[0061] Specifically, such as Figures 1-12 As shown, the third drive assembly 41 includes a primary driver 411 and a secondary driver 412. The output of the primary driver 411 is connected to the secondary driver 412, which can drive the secondary driver 412 to move. The output of the secondary driver 412 is connected to the automatic traction assembly 42, which can drive the automatic traction assembly 42 to pass through the stator 100 and extend into the rotor 300. This enables the automatic traction assembly 42 to move in stages and be precisely positioned, thereby improving the positional accuracy of the traction assembly extending into the stator 100.

[0062] More specifically, in this embodiment, the primary driver 411 includes a first servo motor, a reducer, and a first lead screw. The secondary driver 412 is slidably connected to the support frame 1 via a first linear guide and threadedly connected to the first lead screw to achieve high-precision linear motion of the secondary driver 412. The first servo motor is connected to the first lead screw via a reducer and can drive the first lead screw to rotate around its own axis, thereby driving the secondary driver 412 to move linearly.

[0063] The secondary drive 412 includes a positioning seat, a second servo motor, a planetary reducer, and a second lead screw. The positioning seat is located at the output end of the primary drive 411. The automatic traction component 42 is slidably connected to the positioning seat via a second linear guide and threadedly connected to the second lead screw. The second servo motor is connected to the second lead screw via a planetary reducer and can drive the second lead screw to rotate around its own axis, thereby driving the automatic traction component 42 to move linearly, thereby further improving the accuracy and torque of the secondary drive and ensuring that the automatic traction component 42 can smoothly extend into the rotor 300.

[0064] Specifically, the automatic traction assembly 42 includes a rotary driver 421, a fixed driver 422, and multiple fixed claws 423. The output end of the secondary driver 412 is connected to the rotary driver 421, and the output end of the rotary driver 421 is connected to the fixed driver 422, enabling the fixed driver 422 to rotate, thereby achieving circumferential rotation of the fixed driver 422, which facilitates the fixed claws 423 to adapt to the circumferential position of the end cover 301 of the rotor 300. The output end of the fixed driver 422 is connected to the fixed claws 423, enabling the multiple fixed claws 423 to press against the circumferential direction of the end cover 301 of the rotor 300, thereby achieving uniform circumferential clamping of the end cover 301 and improving the stability and reliability of the fixation.

[0065] The rotary driver 421 can be a structure such as a motor gear or a servo motor, and the fixed driver 422 can be a structure such as a cylinder or a hydraulic cylinder. The specific structure of the above components is not limited here, as long as they can achieve the above functions.

[0066] More specifically, the automatic traction assembly 42 also includes a second sliding member 424 and multiple transmission members 425 corresponding one-to-one with the fixed claws 423. The output end of the rotary driver 421 is provided with a positioning part 4211, which is configured to extend into the rotor 300 to achieve precise positioning of the automatic traction assembly 42 and the rotor 300, providing a reference for the clamping of the fixed claws 423. The second sliding member 424 is slidably disposed on the positioning part 4211. The fixed driver 422 can drive the second sliding member 424 to slide relative to the positioning part 4211. One end of the transmission member 425 is rotatably connected to the second sliding member 424, and the other end is rotatably connected to the corresponding fixed claw 423. Multiple fixed claws 423 are arranged circumferentially at intervals along the positioning part 4211. One end of the fixed claw 423 is rotatably connected to the positioning part 4211, and the other end is configured to abut against the end cover 301, thereby realizing the linkage drive of the fixed claws 423, further ensuring that the clamping force of the fixed claws 423 on the end cover 301 is evenly distributed, and improving the stability of the fixation.

[0067] More specifically, in this embodiment, the second sliding member 424 includes a sliding sleeve, which is slidably fitted onto the positioning part 4211. The transmission member 425 includes a transmission rod, the two ends of which are respectively hinged to the sliding sleeve and the fixed claw 423. When the fixed driver 422 drives the sliding sleeve to move toward the posture adjustment mechanism 3, the transmission rod rotates relative to the sliding sleeve, causing the fixed claw 423 to unfold and abut against the end cover 301 to achieve a tight fit. This achieves automatic unfolding and tight fit of the fixed claw 423, improves the automation level of the clamping operation, and avoids the low efficiency and safety risks caused by manual clamping.

[0068] Specifically, such as Figures 1-7 As shown, the motor assembly device also includes a detection mechanism 5, which comprises a lifting driver 51 and a detection component 52. The lifting driver 51 can drive the detection component 52 to rise and fall, thereby achieving height adjustment of the detection component 52 to adapt to the installation position detection of rotors 300 of different specifications. The detection component 52 is used to detect the installation position of the rotor 300 to provide real-time feedback on the installation status of the rotor 300, promptly detect installation deviations, and make adjustments. The lifting driver 51 includes, but is not limited to, electric push rods and hydraulic cylinders, and the detection component 52 includes, but is not limited to, laser sensors or vision sensors. The specific structure of these components is not limited here, as long as they can achieve the aforementioned functions.

[0069] Specifically, the motor assembly device also includes a working lifting mechanism 6, which includes a lifter 61 and a lifting platform 62. The lifting platform 62 is located at the output end of the lifter 61. The lifter 61 can drive the lifting platform 62 to rise and fall, thereby adjusting the height of the rotor 300 to match the assembly height of the stator 100 and improving the flexibility of the alignment between the stator 100 and the rotor 300. The lifting platform 62 is located between the traction assembly mechanism 4 and the attitude adjustment mechanism 3 and is configured to carry the rotor 300 to be assembled, thereby shortening the moving distance of the rotor 300 from attitude adjustment to assembly and improving work efficiency. The first drive assembly 21 can drive the second clamping assembly 23 to move the rotor 300 onto the lifting platform 62 and wait for the assembly operation, thereby achieving smooth transfer and temporary storage of the rotor 300 and improving the continuity of the assembly process. The detection mechanism 5 is located between the lifting platform 62 and the attitude adjustment mechanism 3 and can detect in a timely manner whether the rotor 300 has moved into position and is waiting for the assembly operation.

[0070] The lifting device 61 includes, but is not limited to, structures such as hydraulic cylinders or electric cylinders. No further restrictions are placed on the specific structure of the lifting device 61.

[0071] Specifically, such as Figures 1-7 As shown, the motor assembly device also includes a locking mechanism 7. The locking mechanism 7 is mounted on the support frame 1 and located between the lifting mechanism 6 and the traction assembly mechanism 4. After the stator 100 and rotor 300 are assembled, it automatically locks and secures them, ensuring the reliability of the connection after assembly and avoiding the inefficiency or insecure locking caused by manual locking, thus improving the overall process continuity. Furthermore, the locking mechanism 7 includes a screw assembly 71 and a clip assembly 72. The screw assembly 71 is used to achieve fully automated operation of the locking process, while the clip assembly 72 is used to continuously and stably supply screws to the screw assembly 71, preventing interruption of screw supply. Through their coordinated operation, the screw locking operation after the stator 100 and rotor 300 are assembled is completed, achieving automatic screw storage, precise delivery, and efficient locking, avoiding assembly quality risks caused by screw supply interruption or misalignment. It should be noted that those skilled in the art are familiar with the specific structure and working principle of the screw assembly 71 and the clip assembly 72, and will not elaborate further here.

[0072] Specifically, the motor assembly device also includes a control mechanism 8. The control mechanism 8 is communicatively connected to the clamping mechanism 2, the attitude adjustment mechanism 3, the traction assembly mechanism 4, the detection mechanism 5, the work lifting mechanism 6, and the locking mechanism 7. It can control the operation of these mechanisms and execute corresponding operations, thereby achieving coordinated linkage and automated control of each mechanism, improving the overall coordination and efficiency of the operation. The control mechanism 8 includes, but is not limited to, a PLC control system and a microcontroller; the specific structure of the control mechanism 8 will not be further limited here.

[0073] Specifically, the motor assembly device also includes a vision mechanism, which analyzes and determines the installation positions of the automatic traction assembly 42, stator 100, and rotor 300, thereby ensuring the accuracy and safety of the assembly operation. Furthermore, those skilled in the art are familiar with the specific structure and working principle of the vision mechanism, and will not elaborate further here.

[0074] The following describes the specific working process of the motor assembly device, including the following:

[0075] The first drive component 21 actuates, driving the first clamping component 22 to move and clamp the fixed base 200 to the unloading station. Specifically, the first drive component 21 drives the first clamping component 22 to move smoothly to the storage position of the fixed base 200. The first clamping driver 221 drives the two first jaws 222 to move towards each other to firmly clamp the fixed base 200 and transfer it to the preset unloading station. This provides a stable carrier for the assembled finished product in advance, avoiding placement confusion or component damage caused by the lack of a corresponding fixed base 200 to receive the finished product during unloading.

[0076] The automatic traction component 42 is positioned at a predetermined point. The fixed base 200 supporting the stator 100 is moved to the first loading station. The first drive component 21 is activated, driving the second clamping component 23 to move and clamp the stator 100 to the first installation position corresponding to the predetermined position. Specifically, the vision mechanism and the control mechanism 8 work together to determine the precise position where the automatic traction component 42 will extend into the stator 100, ensuring the accuracy of the traction path. Then, the fixed seat 200 supporting the stator 100 is moved to the first loading station by a conveying mechanism (such as a conveyor belt, sprocket mechanism, etc.) so that the stator 100 can be positioned subsequently, avoiding misalignment in the subsequent assembly process caused by the deviation of the stator 100 loading position. Then, the first drive component 21 is activated again, driving the second clamping component 23 to move to the first loading station. The second clamping driver 231 drives the two second jaws 232 to move away from each other and extend under the clamping part 101 of the stator 100, thereby stably supporting and clamping the stator 100. Then, the stator 100 is moved to the first installation position corresponding to the preset position of the automatic traction component 42, thereby achieving precise positioning and stable transfer of the stator 100.

[0077] The third drive assembly 41 is activated, driving the automatic traction assembly 42 to extend into the stator 100 at the first installation position. Specifically, the primary drive 411 and the secondary drive 412 work together. First, the primary drive 411 drives the secondary drive 412 to move as a whole to one side of the stator 100. Then, the secondary drive 412 drives the automatic traction assembly 42 to slowly pass through the interior of the stator 100 until it reaches the preset traction starting position. This provides a stable and reliable traction reference for the traction assembly of the rotor 300, avoiding interference between the stator 100 and the rotor 300 during assembly due to improper insertion of the traction assembly.

[0078] The rotor 300 is moved to the second loading station, and the gripping and releasing assembly 32 is moved by the second drive assembly 31 to grip the rotor 300 and move the rotor 300 to the second installation position corresponding to the preset position. Specifically, the rotor 300 to be assembled is moved to the second loading station by a conveying mechanism (such as a conveyor belt, sprocket mechanism, etc.). The second drive assembly 31 drives the gripping and releasing assembly 32 to move quickly above the rotor 300. The fixing part 321 is fitted onto the rotor 300 shaft through the through slot, the insertion part 322 is inserted into the rotor 300, and the locking assembly 33 locks the rotor 300, thereby achieving multiple fixation of the rotor 300 and preventing the rotor 300 from falling off or being damaged due to insecure gripping. Then, the second drive assembly 31 drives the gripping and releasing assembly 32 to move the locked rotor 300 to the second installation position corresponding to the preset position.

[0079] The rotor 300 is pulled into the stator 100 by the automatic traction assembly 42. Specifically, the fixed driver 422 drives the second sliding member 424 to slide, and the transmission member 425 drives multiple fixed claws 423 to unfold synchronously and press against the circumference of the end cover 301 of the rotor 300. Then the rotation driver 421 is activated, and the fixed claws 423 drive the rotor 300 to rotate. After that, the third drive assembly 41 drives the automatic traction assembly 42 to slowly retreat, and smoothly pull the rotor 300 into the stator 100. At this time, the posture adjustment mechanism 3 moves with the rotor 300, thereby realizing the smooth assembly of the stator 100 and the rotor 300, avoiding problems such as uneven traction force and excessive assembly impact caused by manual pushing or overhead crane hoisting, and effectively protecting the stator 100 and the rotor 300 components from damage.

[0080] After the rotor 300 and stator 100 are locked, the first drive assembly 21 actuates, driving the second clamping assembly 23 to move and clamp the locked stator 100 and rotor 300 to the fixed seat 200 at the unloading station. Specifically, after the rotor 300 and stator 100 are fully assembled, the locking mechanism 7 locks the rotor 300 and stator 100 to ensure overall stability after assembly. Subsequently, the rotor 300 is unlocked, and the first drive assembly 21 drives the second clamping assembly 23 to move to the locked finished product location for clamping, and moves the finished product to the fixed seat 200 at the unloading station. This achieves rapid unloading and orderly storage of the finished product, avoids collisions or positional confusion during finished product transfer, and improves the continuity of the overall operation process.

[0081] It should be noted that during the use of the above-mentioned motor assembly device: First, the first drive component 21 is activated, driving the first clamping component 22 to move and clamp the fixed seat 200 to the unloading station, so that the stator 100 and rotor 300 can be unloaded after assembly. The bearing layout of the unloading station is planned in advance to ensure a smooth unloading process and avoid work interruption due to the lack of a fixed seat 200 to support the finished product after assembly. The preset position of the automatic traction component 42 is determined, and the fixed seat 200 supporting the stator 100 is moved to the first loading station. The first drive component 21 is activated, driving the second clamping component 23 to move and clamp the stator 100 to the first installation position corresponding to the preset position. The first drive component 21 drives the first clamping component 22 to move. 22. The second clamping assembly 23 precisely positions and shifts the fixed base 200 and the stator 100 respectively, ensuring that the stator 100 and the fixed base 200 are in place, guaranteeing the smooth progress of subsequent assembly operations. This achieves independent positioning and coordinated operation of the stator 100 and the fixed base 200, improving the accuracy and reliability of component positioning and preventing the overall assembly process from being hindered due to component positioning errors. The third drive assembly 41 actuates, driving the automatic traction assembly 42 to extend into the stator 100 at the first installation position. By precisely extending the automatic traction assembly 42 into a preset position within the stator 100 in advance, a stable reference is provided for the traction assembly of the rotor 300, avoiding the risk of collisions caused by unclear references when manually pushing the rotor 300, and strengthening the traction assembly. The system improves stability, further reducing the probability of damage during the assembly of the stator 100 and rotor 300, and enhancing the consistency of assembly quality. By moving the rotor 300 to the second loading station, the second drive assembly 31 drives the gripping and releasing assembly 32 to grip the rotor 300 and move it to the second installation position corresponding to the preset position. This achieves rapid and precise alignment between the rotor 300 and the stator 100, solving the problems of low rotor 300 adjustment efficiency and poor alignment accuracy in the prior art. This improves the efficiency of rotor 300 adjustment and alignment, shortens the assembly cycle, and ensures consistent alignment accuracy for each assembly, thus enhancing product quality stability. The automatic traction assembly 42 provides a uniform and stable traction force, smoothly moving the rotor 300. The rotor 300 is pulled into the stator 100, thereby reducing the probability of collision damage during the assembly of the stator 100 and rotor 300, achieving precise control of the traction force, avoiding assembly problems caused by excessive or insufficient traction force, further protecting the key components of the stator 100 and rotor 300, and reducing maintenance or production costs; after the rotor 300 and stator 100 are locked, the first drive component 21 is activated, driving the second clamping component 23 to move to clamp the locked stator 100 and rotor 300 and move them to the fixed seat 200 at the unloading station, thereby realizing the automated connection of the entire process of loading, positioning, assembly, and unloading, forming a closed-loop automated operation process, reducing the links of manual intervention, improving operation efficiency, and reducing the quality risks caused by human operation errors.Through the above settings, the motor assembly device of this embodiment can realize the fully automated and coordinated process of stator 100 positioning, rotor 300 attitude adjustment, traction assembly, and finished product unloading. It not only improves the accuracy and efficiency of stator 100 and rotor 300 assembly, but also reduces the intensity of manual operation and the risk of assembly damage. It realizes the standardization, efficiency and safety of assembly operations, and provides a reliable automated assembly solution for the traction motor maintenance industry, avoiding many drawbacks of traditional manual assembly methods.
