Description

Technical Field

[0001] This invention relates to the field of motor assembly technology, and more specifically to a motor component assembly fixture. Background Technology

[0002] Motor components include snap rings, bracket screws, sealing caps, bracket nuts, etc., and their respective functions are as follows:

[0003] 1. Snap ring: It is mainly used to fix the stator coil, ensuring that the stator coil is tightly connected to the rest of the motor, and can also withstand the vibration and impact during the operation of the motor.

[0004] 2. Bracket screws: Used to fix motor components and ensure stable operation of the motor.

[0005] 3. Sealing cover: It serves to prevent dust and seal the motor, preventing internal contamination or dust accumulation that could affect its normal operation.

[0006] 4. Bracket nut: Used in conjunction with bracket screws to increase the stability of the motor.

[0007] These components are generally small in size. Due to cost considerations and the complexity of the installation process, they are usually assembled using mechanical assistance or manual methods. The specific assembly method is as follows:

[0008] 1. Assembly of the snap rings: Snap rings are typically installed at both ends of the stator coils, securing them to the stator frame of the motor to maintain the stability of the stator coils. During installation, ensure the snap rings are clean, with a smooth surface free of impurities. Then, accurately place the snap rings into the slots and gently press until they are fully embedded.

[0009] 2. Bracket Screw Assembly: Select the appropriate screw size based on the rack dimensions and load conditions. Before installation, ensure the rack surface is clean and flat, free of dust, grease, and foreign matter. Then insert the screws into the holes and tighten them with a wrench or electric screwdriver to ensure a tight metal-to-metal connection. When tightening the screws, keep the rack vertical and do not apply excessive force; a pre-tightening is sufficient.

[0010] 3. Assembling the sealing cap: Place the sealing cap in the appropriate position, ensuring it is flat and free from warping. Then, use the bracket screws to secure the sealing cap, tightening the screws in the order of first the middle and then the two sides.

[0011] 4. Assembly of bracket nuts: Place the bracket nuts in the appropriate positions and tighten them with a wrench or electric screwdriver to ensure a tight connection between the nuts and the metal.

[0012] A device for assembling motor insulation components, disclosed in CN117428482A, includes a feeding mechanism 2, an assembly and handling mechanism, a conveyor line, and a testing mechanism. The motor bracket workpiece passes sequentially through the assembly station of the assembly and handling mechanism and the testing station of the testing mechanism via the conveyor line. The motor bracket workpiece is provided with a first area and a second area. The testing mechanism is provided with a plurality of electrical probes located above the testing station. The plurality of electrical probes include at least one first probe and at least one second probe. A preset distance is formed between the first probe and the second probe, and the first probe is located above the first area, and the second probe is located above the second area. By setting multiple electrical probes and observing the electrical properties of the insulation components on the bracket, the installation and testing of the bracket insulation components can be completed quickly, improving testing efficiency, ensuring testing accuracy, and reducing the equipment cost of the testing mechanism. This technology device automates the assembly of motor bracket insulation components. However, this technology device only assembles the insulation components and not the bracket screws and nuts used to fix the bracket. This will cause displacement deviation of the internally assembled insulation components during assembly, leading to an increased defect rate. In addition, this technology device only assembles some insulation components. After assembly, it needs to be transferred to the next tooling equipment, which increases the number of processes, increases equipment costs, and reduces work efficiency. Furthermore, if there are many tooling steps, higher positioning accuracy is required. Summary of the Invention

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] In existing devices, the motor bracket insulation components are assembled automatically. However, this device only assembles the insulation components and not the bracket screws and nuts used to fix the bracket. This can cause displacement deviations in the internally assembled insulation components during assembly, leading to an increased defect rate. Furthermore, this device only assembles a portion of the insulation components, requiring them to be transferred to the next tooling after assembly, which increases the number of processes, equipment costs, and work efficiency. If there are many tooling steps, higher positioning accuracy is also required. To solve the above problems, the following Embodiment 1 and Embodiment 2 are provided.

[0039] Reference Figure 1 and Figure 2 Example 1, Figure 1 This is a schematic front view of the overall structure of Embodiment 1. Figure 2 This is a top view of the overall structure of Embodiment 1. Embodiment 1 is a motor accessory assembly fixture, including a main frame 1. The top of the main frame 1 is provided with a platform 1.11.1. A turntable mechanism 10 is provided in the middle of the platform 1.1. The turntable mechanism 10 is provided with a plurality of equally spaced motor workstations 11. A feeding mechanism is provided between the turntable mechanism 10 and one side of the platform 1.1. The feeding mechanism is located at one corner of the platform 1.1. A bracket screw assembly mechanism 3 is also provided in the middle of the platform 1.1 on the same side as the feeding mechanism. A sealing cover assembly mechanism 4 is provided in the middle of the platform 1.1 on the outer periphery of the turntable mechanism 10. A discharging mechanism 7 is provided at the other end of the platform opposite to the feeding mechanism. A bracket nut assembly mechanism 5 and a pressure testing mechanism 6 are also provided on the platform on the same side as the discharging mechanism 7.

[0040] This motor component assembly fixture is designed with high functionality and efficiency. The turntable mechanism 10 enables continuous operation of multiple motor workstations 11, effectively increasing assembly speed. The evenly spaced design of the turntable mechanism 10 ensures balance and coordination between each workstation, further enhancing work efficiency.

[0041] The feeding mechanism is located at one corner of the platform 1.1, making material supply during the assembly process more convenient. At the same time, the bracket screw assembly mechanism 3 is set on the same side as the feeding mechanism, allowing screw assembly and material feeding to be carried out in parallel, further improving the efficiency of assembly line operations.

[0042] The turntable mechanism 10 has a sealing cover assembly mechanism 4 in the middle of the outer plate 1.1. This design allows the sealing cover to be pre-installed while the motor station 11 is being assembled, which ensures the continuity of the assembly and effectively saves assembly time.

[0043] On the opposite end of the tabletop from the feeding mechanism, there is a discharging mechanism 7, which allows assembled motor parts to be unloaded promptly without affecting subsequent assembly. Simultaneously, on the same side of the tabletop as the discharging mechanism 7, there are also a bracket nut assembly mechanism 5 and a pressure testing mechanism 6. These two mechanisms allow assembled motor parts to be directly fitted with nuts and subjected to pressure tests, further improving the integrity and efficiency of the assembly process.

[0044] In summary, this motor component assembly fixture, through its reasonable design and layout, achieves high efficiency and automation in the assembly process, greatly improving assembly efficiency and quality.

[0045] Reference Figure 3This is a schematic diagram of the feeding mechanism in Embodiment 1. The feeding mechanism includes a feeding conveyor belt 2.3 for transporting the motor to be processed. The feeding conveyor belt 2.3 is located at the edge of the table and points towards the turntable mechanism 10, thus allowing external transport of the motor to be processed to the turntable. A feeding slide rail is also mounted on the table 1.1 between the feeding conveyor belt 2.3 and the turntable mechanism 10. The feeding slide rail connects the feeding conveyor belt 2.3 and the turntable mechanism 10. A gripping mechanism 2.2 is slidably connected to the feeding slide rail. The gripping mechanism 2.2 is used to grip and transport the motor to be processed on the feeding conveyor belt 2.3 to the motor station 11 on the turntable mechanism 10, so that the next process operation can be performed. The gripping mechanism 2.2 includes a sliding seat 2.22, which is slidably fixed to the feeding slide rail. A telescopic cylinder 2.21 is mounted on the sliding seat 2.22. The telescopic end of the telescopic cylinder 2.21 is connected to a gripping mechanism 2.2. The gripping mechanism 2.2 includes a gripping seat with multiple grippers 2.24 mounted on it. The grippers 2.24 are made of rubber and have sufficient friction and flexibility to ensure stable gripping of materials of various shapes and sizes. The gripping mechanism 2.2 slides on the feeding slide rail through the telescopic movement of the telescopic cylinder 2.21, realizing the gripping and transfer of materials.

[0046] The turntable mechanism 10 includes a turntable and a drive device for rotating the turntable. The turntable is located above the tabletop, and its upper surface is provided with multiple motor stations 11. The motor stations 11 are matched with the gripping claws of the gripping mechanism 2.2 to ensure that the gripping mechanism 2.2 can accurately place materials at designated positions on the turntable. The drive device provides stable rotational power to the turntable, enabling it to rotate at a set speed and direction to transport materials to the next process.

[0047] The entire feeding mechanism is reasonably designed and easy to operate, enabling an automated and efficient material feeding process, which greatly improves production efficiency and quality.

[0048] Reference Figure 4 This is a front view schematic diagram of the bracket screw assembly mechanism 3 in Embodiment 1. The bracket screw assembly mechanism 3 in the figure includes a material transfer guide rail 3.2, a sliding seat 3.3 slidably connected to the material transfer guide rail 3.2, and a pressing lower mold 3.10 fixed on the sliding seat 3.3. The bracket screw assembly mechanism 3 also includes a fixed seat, which is fixed on the table 1.1. The fixed seat is provided with a lifting cylinder 3.4 and connected to a sliding plate 3.5. The sliding plate 3.5 is also provided with a clamping device, which is used to clamp the motor to be processed on the turntable mechanism 10.

[0049] The bracket screw assembly mechanism 3 shown in the figure is ingeniously designed and fully functional. The design of the material transfer guide rail 3.2 ensures that the sliding seat 3.3 can slide stably and smoothly on it, thereby precisely controlling the position of the press-fit lower die 3.10. The fixing of the press-fit lower die 3.10 ensures its stability and reliability when performing the press-fit task.

[0050] Furthermore, the fixed base further enhances the stability of the mechanism. The fixed base is secured to the platform 1.1, ensuring the stability of the entire mechanism during operation. The second lifting cylinder 3.4 is installed within the fixed base and, through its connection with the sliding plate 3.5, enables precise lifting movements. This design not only simplifies the mechanism's structure but also improves the accuracy and stability of the lifting actions.

[0051] The clamping device on the sliding plate 3.5 further enhances the practicality of the mechanism. This device precisely clamps the motor to be processed, ensuring assembly accuracy and efficiency. At the same time, the design of the clamping device fully considers ease of operation and safety, allowing operators to easily complete assembly tasks.

[0052] The bracket screw assembly mechanism 3 further includes a transverse guide rail 3.6, mounted on the top of the fixed base, and the transverse guide rail 3.6 is perpendicular to the material transfer guide rail 3.2. A sliding plate 3.7 is slidably fixed on the transverse guide rail 3.6, and a pressing die 3.9 is fixed on the sliding plate. The pressing die 3.9 can slide flexibly along the transverse guide rail. A bracket screw vibratory feeder 3.1 is also provided on the platform 1.1 at one end of the transverse guide rail 3.6, which is connected to the fixed base and the pressing die 3.9. Correspondingly, the upper pressing die 3.9 facilitates the clamping of the bracket screws stored in the bracket screw vibratory plate 3.1. In addition, the lower pressing die 3.10 corresponds to the upper pressing die 3.9. The lower pressing die 3.10 is used to grip and transport the motor to be processed that is gripped by the clamping device from the turntable mechanism 10. After the lower pressing die 3.10 grips and fixes the motor to be processed, the lower pressing die 3.10 drives the motor to be processed to move along the material transfer guide rail 3.2 to below the upper pressing die 3.9, thereby starting the bracket screw assembly process.

[0053] Furthermore, a precision control system is integrated at the press-fit upper die 3.9 of the bracket screw assembly mechanism 3. This system consists of a set of high-precision sensors and a microprocessor. The high-precision sensors are installed at key locations on the press-fit upper die 3.9 and the bracket screw vibratory feeder 3.1 to monitor various parameters during the assembly process in real time, such as screw position, speed, and force. This parameter data is transmitted to the microprocessor in real time for analysis and processing.

[0054] The microprocessor performs calculations and judgments based on the received data using a preset algorithm, and then issues corresponding control commands. These commands, through the electrical control system, precisely control the movement of the sliding plate 3.7 on the transverse guide rail 3.6, and the up-and-down movement of the pressing mold 3.9, thereby achieving precise assembly of the bracket screws.

[0055] Furthermore, to ensure assembly efficiency and precision, the system can also be equipped with an automatic lubrication device and an automatic cleaning device. The automatic lubrication device periodically lubricates the transverse guide rail 3.6 and the transfer guide rail to ensure smooth movement of the sliding plate 3.7 and the transfer plate. The automatic cleaning device periodically cleans the vibratory feeder and assembly area to prevent dust and impurities from affecting the assembly process. This results in a higher degree of automation, higher operational precision, and more stable operation of the device in this embodiment.

[0056] Reference Figure 5 This is a front view schematic diagram of the sealing cap assembly mechanism 4 in this embodiment 1. The sealing cap assembly mechanism 4 is located at the edge of the turntable mechanism 10 in the middle of the platform 1.1. The sealing cap assembly mechanism 4 includes a material transfer guide rail 4.2. One end of the material transfer guide rail 4.2 points towards the turntable mechanism 10, and a suction mechanism 4.3 is slidably fixed on the material transfer guide rail 4.2. The suction mechanism 4.3 is provided with a vacuum suction head 4.4. A sealing cap vibrating plate 4.1 is also provided around the other end of the material transfer guide rail 4.2.

[0057] In this meticulously designed assembly process, the sealing cap assembly mechanism 4 plays a crucial role. It is located at the edge of the turntable mechanism 10 in the middle of the platform 1.1, after the bracket screw assembly process. The sealing cap assembly mechanism 4 mainly includes the material transfer guide rail 4.2, which is a key component. Its design ensures that the suction mechanism 4.3 can move accurately.

[0058] One end of the transfer guide rail 4.2 points towards the turntable mechanism 10, which means that the suction mechanism 4.3 can move precisely and flexibly with the turntable mechanism 10 under the guidance of the transfer guide rail 4.2. At the same time, the suction mechanism 4.3 is slidably fixed on the transfer guide rail 4.2. In this embodiment, the suction mechanism 4.3 is an electrically driven vacuum pump used to provide vacuum suction to facilitate the suction of the sealing cap.

[0059] The suction mechanism 4.3 is equipped with a vacuum suction head 4.4. The size of the vacuum suction head 4.4 must match the sealing cap to facilitate accurate suction of the sealing cap. When the suction mechanism 4.3 moves to the appropriate position, the vacuum suction head 4.4 will be activated and will hold the sealing cap to be suctioned on the cap moving guide rail 4.6. This design greatly improves the efficiency and accuracy of assembly and reduces the error rate of manual operation.

[0060] At the other end of the transfer guide rail 4.2, there is also a sealing cap vibrating plate 4.1. This is a device for storing and transporting sealing caps. It uses vibration to transport the sealing caps one by one to the position of the cap transfer guide rail 4.6. In this way, the suction mechanism 4.3 can pick up the sealing caps from the cap transfer guide rail 4.6 at any time for assembly operations. This design not only improves the continuity of assembly, but also makes the assembly process more automated and intelligent.

[0061] The transfer guide rail 4.2 is located near one end of the sealing cap vibratory plate 4.1 and is mounted on a platform 1.1 corresponding to the vacuum suction head 4.4. The mounting platform is located below the vacuum suction head and is connected to one end of the transfer guide rail 4.6. The sealing cap on the transfer guide rail 4.6 will eventually move to the mounting platform to be picked up by the vacuum suction head 4.4. One end of the transfer guide rail 4.6 is connected to the mounting platform, and the other end is connected to the sealing cap vibratory plate 4.1. The sealing cap vibratory plate 4.1 is slightly higher than the mounting platform, which increases the speed at which the sealing cap moves to the mounting platform. In addition, the transfer guide rail 4.6 can also be a conveyor belt, which can further increase the processing efficiency.

[0062] Reference Figure 6 This is a front view schematic diagram of the bracket nut assembly mechanism 5 in this embodiment 1. The bracket nut assembly mechanism 5 includes a material transfer guide rail 3 5.2, on which a lifting cylinder 4 5.3 is slidably connected. The lifting cylinder 4 5.3 is connected to the assembly upper mold 5.4. The bottom of the assembly upper mold 5.4 is also provided with a spring push rod 5.5, which corresponds to the turntable mechanism 10.

[0063] The turntable mechanism 10 includes a rotary drive device and a turntable body, the rotary drive device driving the turntable body to rotate. The turntable body has multiple motor stations 11, each corresponding to a spring push rod 5.5. When the upper mold 5.4 descends to the assembly position, the spring push rod 5.5 pushes the assembly nut into the bracket hole on the assembly station, completing the assembly of the bracket nut.

[0064] In addition, the bracket nut assembly mechanism 5 also includes sensors and a control system. The sensors are used to detect the position and state of various components during assembly, such as the position of the upper mold 5.4 and the state of the spring push rod 5.5. Based on the feedback signals from the sensors, the control system controls the actions of actuators such as the lifting cylinder 5.3 and the rotary drive device to ensure the smooth progress of the assembly process.

[0065] Reference Figure 8This is a schematic diagram of the feeding mechanism 7 in Embodiment 1. The feeding mechanism 7 includes a transfer guide rail 7.1, on which a lifting motor 7.2 is mounted. The lifting motor 7.2 is connected to a clamping mechanism 7.3. The lifting motor 7.2 can provide the necessary power through precise control to drive the clamping mechanism 7.3 to perform lifting operations. Furthermore, the lifting motor 7.2 and the clamping mechanism 7.3 are directly connected by a movable joint, allowing the clamping mechanism 7.3 to bend freely, thereby enabling the separate loading and unloading of the clamped motors. The platform 1.1 corresponding to the clamping mechanism 7.3 is equipped with two parallel conveyor belts, namely an upper conveyor belt and a lower conveyor belt 8. In this embodiment, the two parallel conveyor belts on the platform 1.1, namely the upper conveyor belt 9 and the lower conveyor belt 8, correspond to qualified and unqualified products, respectively. The qualified and unqualified motors are distributed by bending through the movable joint between the clamping mechanism 7.3 and the lifting motor 7.2.

[0066] It is worth mentioning that a movable joint is provided between the lifting motor 7.2 and the clamping mechanism 7.3. This design not only increases the flexibility of the mechanism, but also enables the clamping mechanism 7.3 to operate at different heights and angles, further improving the accuracy and efficiency of material unloading.

[0067] Furthermore, as summarized above, this feeding mechanism 7, through its ingenious design and precise control, achieves rapid and accurate material feeding, significantly improving production efficiency and product quality. At the same time, its modular and easily maintainable design makes this mechanism more flexible and convenient in practical applications.

[0068] exist Figure 2 Based on this, further refinement of the technical solutions regarding shape, structure, positional relationships, and connection relationships yields Embodiment 2. Embodiment 2 is identical to Embodiment 1, both being a motor component assembly fixture. Furthermore, Embodiment 2 is an extension and expansion of this motor component assembly fixture, referring to... Figure 2 The figure shows a top view of the overall structure of Embodiment 2. The bottom plate 1.1 of the feeding slide rail of the feeding mechanism is also provided with a snap ring mounting mechanism 12. The snap ring mounting mechanism 12 matches the gripper 2.24. In this embodiment, the snap ring mounting mechanism 12 is located at the bottom of the feeding slide rail. The clamp 2.24 of the feeding mechanism is used to realize the snap ring mounting process, which saves equipment costs.

[0069] The snap ring mounting mechanism 12 consists of a set of precision mechanical components, including a guide rail, a positioning block, and a spring snap ring. When the gripper 2.24 holds the material and moves it to the designated position along the feeding slide rail, the guide rail guides the gripper 2.24 to accurately enter the working area of ​​the snap ring mounting mechanism 12. At this time, the positioning block automatically locks the position of the gripper 2.24 to ensure the stability of the material during the assembly process.

[0070] Subsequently, the elastic retaining ring is quickly and accurately installed onto the material under a preset force. During this process, the coordinated operation of the retaining ring installation mechanism 12 and the gripper 2.24 ensures the accuracy and efficiency of the retaining ring installation. The entire feeding and assembly process is smooth and efficient, greatly improving the automation level and capacity of the production line.

[0071] Reference Figure 7 This is a front view schematic diagram of the pressure resistance testing mechanism in this embodiment. The pressure resistance testing mechanism 6 is securely mounted on the platform 1.1 via a mounting slot 6.1. This design not only ensures the stability of the test but also facilitates daily maintenance and upkeep. The precise installation of the displacement sensor 6.2 and the probe makes the testing process more accurate and reliable. The displacement sensor 6.2 can monitor the positional changes of the probe in real time, ensuring the accuracy of the test data. The probe corresponds to a motor station 11 of the turntable mechanism 10. This design allows each motor station 11 to undergo pressure resistance testing, ensuring the consistency of product quality.

[0072] During the test, the pressure testing mechanism 6 gradually increases the pressure on the motor station 11 according to a preset program, while the displacement sensor 6.2 monitors the displacement of the probe in real time. When the motor station 11 experiences a displacement change during the pressure increase, the displacement sensor 6.2 immediately feeds this information back to the control system. The control system then makes corresponding adjustments based on the feedback information to ensure the accuracy and reliability of the test. The feedback information is transmitted to the control system of the unloading mechanism 7, where unqualified products are sorted into the lower conveyor belt 8 via the clamping mechanism 7.3, and qualified products are sorted into the upper conveyor belt 9.

[0073] The workflow of embodiments 1 and 2 is as follows: feed conveyor 2.3 flows into motor - feeding mechanism - install snap ring - turntable mechanism 10 - install bracket screw - turntable mechanism 10 - install sealing cover - turntable mechanism 10 - install bracket nut - turntable mechanism 10 - pressure test - unloading mechanism 7 - flow out of upper conveyor 9 or lower conveyor 8.

[0074] The working steps of embodiments 1 and 2 are as follows:

[0075] Feeding process: The material flows into the motor to be processed via the feeding conveyor belt 2.3.

[0076] Feeding process: The feeding mechanism picks up the motor to be processed.

[0077] Installing the snap ring: The snap ring installation mechanism 12 uses the clamping jaws 2.24 of the feeding mechanism to clamp the motor to be processed to the snap ring installation mechanism 12 to complete the snap ring installation. Then, the clamping jaws 2.24 clamp the motor to be processed and send it into the turntable mechanism 10.

[0078] Turntable process: The motor to be processed is installed onto the motor station 11 of the turntable mechanism 10 by the clamp 2.24 of the feeding mechanism. The turntable rotates clockwise and enters the next process.

[0079] Install bracket screws: The clamping device of the bracket screw assembly mechanism 3 picks up the motor to be processed on the turntable and transfers it to the lower pressing die 3.10. Then, the lower pressing die 3.10 picks up the motor to be processed and transfers it to the upper pressing die 3.9 for bracket screw pressing. After pressing, the motor to be processed is sent back to the motor station 11 on the turntable.

[0080] Installing the sealing cap: The sealing cap assembly mechanism 4's suction mechanism 4.3 uses a vacuum suction head 4.4 to pick up the sealing cap on the mounting table, and then uses the transfer slide rail 2 to directly transport the sealing cap to the motor station 11 of the turntable mechanism 10 to complete the sealing cap installation process.

[0081] Install bracket nut: When the upper mold 5.4 descends to the assembly position, the spring push rod 5.5 pushes the assembly nut into the bracket hole on the assembly station, completing the assembly of the bracket nut.

[0082] Withstand pressure test: The withstand pressure testing mechanism 6 will gradually increase the pressure on the motor station 11 according to a preset program, while the displacement sensor 6.2 will monitor the displacement of the probe in real time. When the displacement of the motor station 11 changes during the pressurization process, the displacement sensor 6.2 will immediately feed this information back to the control system. The control system will make corresponding adjustments based on the feedback information to ensure the accuracy and reliability of the test.

[0083] Material unloading process: The pressure resistance test feedback information is transmitted to the control system of the unloading mechanism 7. The unqualified products are sorted into the lower conveyor belt 8 by the clamping mechanism 7.3, and the qualified products are sorted into the upper conveyor belt 9.

[0084] The beneficial effects of embodiments 1 and 2 are:

[0085] This embodiment of the motor component assembly fixture integrates a turntable mechanism 10, a feeding mechanism, a bracket screw assembly mechanism 3, a sealing cover assembly mechanism 4, a unloading mechanism 7, a bracket nut assembly mechanism 5, a withstand voltage testing mechanism 6, and an unloading mechanism 7. Through their coordinated operation, automated assembly of motor components is achieved, significantly improving assembly efficiency, reducing equipment costs, and minimizing process steps, thus increasing work efficiency. The collaborative work between these mechanisms ensures high assembly precision, reduces the defect rate, and improves product quality.

[0086] First, the design of the turntable mechanism 10 allows the motor stations 11 to be evenly distributed, facilitating continuous operation of the assembly fixture. The feeding mechanism transports motor parts to the turntable mechanism 10 via the feeding conveyor belt 2.3 and the feeding slide rail, while the gripping mechanism 2.2 is responsible for gripping the motor parts for assembly, greatly improving assembly efficiency.

[0087] Secondly, the design of the bracket screw assembly mechanism 3 and the bracket nut assembly mechanism 5 enables the bracket screws and bracket nuts to be automatically assembled onto the motor components, avoiding the tediousness and errors of manual assembly and improving assembly accuracy. Meanwhile, the design of the sealing cover assembly mechanism 4 enables the sealing cover to be automatically assembled onto the motor components, further improving assembly efficiency.

[0088] Furthermore, the design of the unloading mechanism 7 enables automatic unloading of assembled motor components, avoiding the tediousness and errors of manual unloading. The design of the withstand voltage testing mechanism 6 allows for withstand voltage testing of the assembled motor components, ensuring product quality.

[0089] Finally, the design of the snap ring mounting mechanism 12 enables the snap ring to be automatically installed on the motor accessories. The snap ring installation process is completed with the help of the gripper 2.24 of the feeding mechanism, saving process time and equipment costs.

[0090] This further improves assembly efficiency. The entire assembly fixture is compact in design, rational in structure, and easy to maintain and upgrade.

[0091] In summary, the motor component assembly fixture of the present invention has the advantages of automation, high efficiency, precision and stability, and can be widely used in the assembly process of motor components.

[0092] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any simple modifications, alterations, and equivalent transformations made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the technical solution of the present invention.
