Description

Technical Field

[0001] This utility model relates to a motor assembly device, and more particularly to a motor assembly flipping and positioning machine. Background Technology

[0002] In the current assembly process of medium and large-sized motors, the rotor is mainly hoisted and assembled manually. Manually hoisting the rotor is not only time-consuming and labor-intensive, but also prone to improper operation due to its weight and size, increasing the difficulty and risk of assembly. Therefore, the existing manual assembly method is not only inefficient, but also cannot fully guarantee safety, limiting further improvements in production efficiency.

[0003] Furthermore, the manual assembly process relies on the operator's experience and skill level, making it difficult to achieve standardization and consistency in the context of multi-batch, large-scale production. Therefore, to ensure the quality and performance of the motor, frequent manual adjustments and calibrations are required, increasing the assembly cycle and consequently impacting the product's market competitiveness.

[0004] To address the aforementioned issues, the applicant developed an automatic motor assembly machine. As a crucial step, it is necessary to precisely position the motor housing, i.e., the stator, in order to facilitate the smooth assembly of the rotor at the rear end. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a motor assembly flipping positioner that is compact in structure, convenient for feeding and adjustment, and can ensure stator accuracy.

[0006] This utility model provides a motor assembly flipping and positioning machine, comprising:

[0007] The base serves as the mounting platform;

[0008] The slide block is horizontally slidably mounted on the base.

[0009] The lifting seat is vertically slidably mounted on the slide.

[0010] The first rotating seat includes a rotating seat body rotatably mounted on the lifting seat and a flipping platform fixed to the end of the rotating seat body, wherein the rotation axis of the rotating seat body is parallel to the sliding direction of the slide.

[0011] The second rotating seat is rotatably mounted on the flipping platform. The rotation axis of the second rotating seat is perpendicular to the rotation axis of the rotating seat body. The end of the second rotating seat forms a mounting platform surface for mounting the motor housing to be assembled. The mounting platform surface is parallel to the rotation axis of the rotating seat body.

[0012] The slide, the lifting seat, the rotating seat body, and the flipping platform are arranged sequentially along the sliding direction of the slide;

[0013] A first driving mechanism is connected to the slide block and is used to drive the slide block to move between the first work station and the second work station;

[0014] The second drive mechanism is connected to the lifting seat and is used to drive the lifting seat to move vertically.

[0015] The third driving mechanism is connected to the rotating seat body and is used to drive the rotating seat body to rotate.

[0016] The fourth drive mechanism is connected to the second rotating seat and is used to drive the second rotating seat to rotate.

[0017] In this application, the mounting platform has a degree of freedom in vertical lifting and two rotational directions, which enables the motor housing to achieve almost any desired posture in space, thus realizing the rapid installation and precise positioning of the motor housing.

[0018] The vertical lifting mechanism allows for precise adjustment of the motor's height, perfectly adapting to the working habits of operators of different heights, reducing labor intensity, and seamlessly integrating with subsequent assembly processes, significantly improving assembly efficiency and precision. The dual-rotating-axis design enables flipping and repositioning. The rotation of the first rotating seat easily changes the motor from a vertical to a horizontal position, or allows for turning, facilitating the quick and effortless installation of the hoisted motor housing onto the mounting platform. The second rotating seat allows for precise angle adjustments, facilitating work on the motor housing and ensuring precision for subsequent assembly. Simultaneously, the sliding block allows for horizontal sliding, enabling movement between the first and second workstations. The first workstation serves as the loading, installation, and alignment station for the motor housing, and can also be used for installing other components besides the rotor. The second workstation serves as the stator assembly station, allowing for seamless switching between the two workstations, facilitating assembly line operations.

[0019] Furthermore, a tooling plate for mounting the motor housing is detachably mounted on the mounting platform surface.

[0020] Furthermore, the rotation axis of the second rotating seat is perpendicular to and intersects with the rotation axis of the rotating seat body.

[0021] Furthermore, the first drive mechanism and / or the second drive mechanism are lead screw and nut assemblies.

[0022] Furthermore, the third drive mechanism and / or the fourth drive mechanism are worm gear assemblies.

[0023] Furthermore, the rotating base body has a rotation angle of ±90° and can rotate the vertical motor housing to a horizontal state.

[0024] Furthermore, the worm end of the fourth drive mechanism is equipped with a handwheel that can be manually adjusted.

[0025] Furthermore, the base includes a base body and a pedal disposed on the base body.

[0026] Furthermore, the mounting platform surface is eccentric to the rotation axis of the rotating seat body, and the mounting platform surface faces the rotation axis of the rotating seat body.

[0027] This utility model of a motor assembly flipping and positioning machine integrates all actions into one unit, saving a significant amount of non-value-added time and reducing repetitive hoisting and handling. After the motor housing is installed on the mounting platform, the machine's movement can complete operations in all directions, avoiding precision errors and surface scratches caused by multiple re-clamping, enabling multi-faceted operations with a single clamping. Furthermore, the machine-driven flipping and movement are smooth and precise, preventing component damage or assembly defects that may occur due to fatigue or uneven force during manual operation, thus improving the consistency of assembly quality. This utility model of a motor assembly flipping and positioning machine frees manpower from heavy, repetitive, and risky handling and posture adjustment work. Through precise mechatronics control, it achieves accurate, efficient, and programmable motor assembly processes, improving production efficiency and product quality, as well as the working environment, operational safety, and automation level. It is suitable for the flexible assembly needs of various motor models and offers high flexibility in use. Attached Figure Description

[0033] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] See Figures 1-4 This utility model provides a motor assembly flipping and positioning machine, which includes a base 11, a slide 12, a lifting seat 13, a first rotating seat and a second rotating seat 16.

[0035] The base 11 serves as the installation carrier, placed on the ground to provide a stable support foundation, and is fixedly connected to the ground by anchor bolts to ensure the stability and safety of the equipment during operation.

[0036] The slide block 12 is horizontally mounted on the base 11 and is connected to the first drive mechanism 114. In this embodiment, the first drive mechanism 114 is mounted on the base 11 and is used to drive the slide block 12 to move horizontally between the first station and the second station.

[0037] The lifting seat 13 is vertically slidably mounted on the slide seat 12 and is connected to the second drive mechanism 123. In this embodiment, the second drive mechanism 123 is mounted on the slide seat 12 and is used to drive the lifting seat 13 to move up and down in the vertical direction to achieve lifting.

[0038] The first rotating seat is rotatably mounted on the lifting seat 13, and the rotation axis of the first rotating seat is parallel to the sliding direction of the slide 12. It is connected to the third driving mechanism. In this embodiment, the third driving mechanism is mounted on the lifting seat 13 and is used to drive the first rotating seat to rotate around its rotation axis. Specifically, the first rotating seat includes a rotating seat body rotatably mounted on the lifting seat and a flipping platform fixed to the end of the rotating seat body. The rotation axis of the rotating seat body is parallel to the sliding direction of the slide. The third driving mechanism is connected to the rotating seat body.

[0039] The second rotating seat 16 is rotatably mounted on the first rotating seat, and the rotation axis of the second rotating seat 16 is perpendicular to the rotation axis of the first rotating seat. Preferably, the rotation axis of the second rotating seat 16 is perpendicular to and intersects the rotation axis of the first rotating seat. A mounting platform surface is formed at the end of the second rotating seat 16 for mounting the motor housing (i.e., stator) to be assembled. The second rotating seat 16 is connected to the fourth drive mechanism. In this embodiment, the fourth drive mechanism is mounted on the first rotating seat and is used to drive the second rotating seat 16 to rotate around its rotation axis.

[0040] In this application, the mounting platform has a degree of freedom in vertical lifting and two rotational directions, which enables the motor housing to achieve almost any desired posture in space, thus realizing the rapid installation and precise positioning of the motor housing.

[0041] The vertical lifting mechanism allows for precise adjustment of the motor's height, perfectly adapting to the working habits of operators of different heights, reducing labor intensity, and seamlessly integrating with subsequent assembly processes, significantly improving assembly efficiency and precision. The dual-rotating-axis design enables flipping and repositioning. The rotation of the first rotating seat easily changes the motor from a vertical to a horizontal position, or allows for turning, facilitating the quick and effortless installation of the hoisted motor housing onto the mounting platform. The second rotating seat allows for precise angle adjustments, facilitating work on the motor housing and ensuring precision for subsequent assembly. Simultaneously, the sliding block allows for horizontal sliding, enabling movement between the first and second workstations. The first workstation serves as the loading, installation, and alignment station for the motor housing, and can also be used for installing other components besides the rotor. The second workstation serves as the stator assembly station, allowing for seamless switching between the two workstations, facilitating assembly line operations.

[0042] In this application, the slide 12, lifting seat 13, rotating seat body 14, and tilting platform 15 are arranged sequentially along the sliding direction of the slide 12. For ease of explanation, the first station is taken as the front end and the second station as the rear end, so the slide 12, lifting seat 13, rotating seat body 14, and tilting platform 15 are arranged sequentially from front to back. When moved to the second station, the second rotating seat 16 and part of the tilting platform 15 can be located in the assembly area of ​​the second station, avoiding interference with the rotor assembly device 2 at the rear end, thereby ensuring the stability and safety of the assembly process.

[0043] In this embodiment, when the second rotating seat 16 is in a horizontal state, the first rotating seat, the lifting seat 13 and the slide seat 12 form a symmetrical structure, and the rotation axes of the first rotating seat and the second rotating seat 16 are located on their symmetrical plane.

[0044] In this embodiment, a tooling plate 17 for mounting the motor housing is detachably mounted on the mounting platform. The tooling plate 17 serves as the mounting carrier for the motor housing. It has a detachable structure and can be replaced with different types of tooling plates to adapt to the installation requirements of different models of motor housings, thereby improving the versatility and flexibility of the equipment.

[0045] In this application, the first drive mechanism 114 and the second drive mechanism 123 are both lead screw and nut assemblies. The lead screw and nut assembly includes a lead screw and a nut that mesh with each other. At the same time, the lead screw is connected to a motor and serves as the power end to drive the lead screw to rotate, thereby achieving relative sliding between the lead screw and the nut. The motor in this application is a servo motor, which can achieve precise displacement control of the slide 12 and the lifting seat 13, ensuring the movement accuracy of the slide 12 in the horizontal direction and the lifting seat 13 in the vertical direction, and providing a strong guarantee for the rapid and precise assembly of the motor.

[0046] Furthermore, the third and fourth drive mechanisms are worm gear assemblies, which include a meshing worm wheel and a worm. The worm is connected to a power end for rotation, which is a servo motor for precise control. In this application, to improve work efficiency, the end of the worm on the fourth drive mechanism is connected to a handwheel 18 for manual adjustment. The worm gear design creates a large reduction ratio, allowing a servo motor with a small torque and high speed to output extremely high torque and extremely low speed motion. This is ideal for positioners that require low-speed, smooth, and high-torque rotation and flipping, easily driving the heavy motor housing to rotate smoothly without jerking. Simultaneously, the worm gear assembly has a self-locking function, maintaining its current position when power is off or drive stops, preventing accidental displacement due to gravity or other external forces, thus improving the safety and reliability of equipment operation.

[0047] The first rotating seat has a rotation angle of ±90°, which can rotate the motor housing from a vertical state to a horizontal state. In this application, the horizontal state is taken as 0° and ±90°, that is, it can rotate 90 degrees to both sides and can switch between vertical and horizontal states. In the vertical state, the motor housing can be hoisted, loaded and fixed, which greatly improves the assembly efficiency and ease of operation.

[0048] The first rotating seat in this application includes a rotating seat body 14 rotatably mounted on a lifting seat 13 and a flipping platform 15 fixed to the end of the rotating seat body 14. The flipping platform 15 and the rotating seat body 14 form an L-shaped structure. The second rotating seat 16 is rotatably mounted on the flipping platform 15. The mounting platform surface at the end of the second rotating seat 16 is parallel to the rotation axis of the rotating seat body 14. Specifically, the mounting platform surface is eccentric to the rotation axis of the rotating seat body 14, and the mounting platform surface faces the rotation axis of the rotating seat body 14.

[0049] After installing the motor housing, the overall center of gravity is brought close to the rotation axis of the rotating base body 14, thereby improving the stability and rotation accuracy of the structure. At the same time, during the rotation process, whether it is the first rotating base or the second rotating base, the rotation axis is brought close to the center of gravity of the motor housing, providing an unobstructed working space for the rotation of the motor housing and avoiding interference or collision during the rotation process.

[0050] Meanwhile, the base 11 includes a base body and a pedal disposed on the base body, which forms a working platform to facilitate technicians to assemble and position the motor housing on the working platform.

[0051] To enhance operational safety, a safety fence is installed outside the motor assembly and flipping positioner. The fence is equipped with sliding doors, including an entrance door for personnel and a partition door between the first and second workstations. This is to improve operational safety and prevent unauthorized personnel from entering during the assembly process and causing safety hazards.

[0052] This utility model of a motor assembly flipping and positioning machine integrates all actions into one unit, saving a significant amount of non-value-added time and reducing repetitive hoisting and handling. After the motor housing is installed on the mounting platform, the machine's movement can complete operations in all directions, avoiding precision errors and surface scratches caused by multiple re-clamping, enabling multi-faceted operations with a single clamping. Furthermore, the machine-driven flipping and movement are smooth and precise, preventing component damage or assembly defects that may occur due to fatigue or uneven force during manual operation, thus improving the consistency of assembly quality.

Through precise mechatronics control, it achieves accurate, efficient, and programmable motor assembly processes, improving production efficiency and product quality, as well as the working environment, operational safety, and automation level. It is suitable for the flexible assembly needs of various motor models and offers high flexibility in use.

[0053] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
