Description

Technical Field

[0001] This application relates to the field of aircraft engine assembly technology, and specifically to an electric lifting and tilting machine for auxiliary installation of aircraft engines. Background Technology

[0002] In the aviation manufacturing industry, aero engines provide power for aircraft flight, and their assembly precision and efficiency are crucial to the performance of the entire aircraft. The assembly process of aero engines is complex. Currently, traditional engine installation methods mainly rely on manual operation and simple mechanical auxiliary equipment. However, the installation process of aero engines is characterized by the large size, complex structure, and large number of engine parts, making assembly difficult and the level of automation relatively low. At the same time, each process of adjusting the engine attitude during assembly is time-consuming and labor-intensive, which presents some obvious limitations.

[0003] Therefore, to solve the above problems, the commonly used method for adjusting the engine mounting posture is to use two lifting devices. One end of the engine is manually fixed to the lifting device, which then moves the engine to an open location. After stabilization, the other lifting device is manually installed on the other end of the engine. The two lifting devices work together to flip the engine to the desired posture. Although the existing technical solution can optimize the adjustment of the engine posture to some extent, this solution has some technical defects. For example, during the flipping process, manual assistance is required to install the engine onto the lifting device. This process is time-consuming and labor-intensive. Each posture adjustment requires reinstalling the lifting device, which affects engine assembly and is very inefficient. Furthermore, the flipping of the lifting device is unstable, and the angle and posture of the flipped position depend entirely on manual perception, which cannot guarantee the required flipping posture, resulting in poor stability and reliability.

[0004] Therefore, a new type of electric lifting and tilting machine is needed. Utility Model Content

[0045] In addition, specific details are provided in the following description to facilitate a thorough understanding of the examples.

[0046] Aircraft engines provide power for aircraft flight, and as the heart of an aircraft, they are often referred to as the "flower of industry."

[0047] Currently, aviation technology is developing rapidly, and engines need to be constantly updated to meet new flight requirements. Due to the complexity and number of components, the engine assembly process is extremely difficult. The manufacturing process of aero engines involves multiple fields such as precision machining, materials science, and thermodynamics, requiring a high level of craftsmanship and technology. Generally speaking, engine components are large in size, complex in structure, and numerous, making assembly difficult and with a low level of automation. This is not only due to the complexity of the aero engine manufacturing process, but also because the requirements for the assembly stage are extremely precise, requiring accurate fit to ensure the engine's efficient operation. Every adjustment of the engine's attitude during assembly is time-consuming and labor-intensive.

[0048] Currently, the assembly process of aero engines is still at a low level of automation, and many steps still require manual operation. This increases the difficulty and time cost of assembly. The installation process of aero engines is an extremely challenging task, involving highly precise and complex technical issues.

[0049] First, engines are enormous and complex, composed of thousands of precision parts, each requiring accurate positioning and assembly. Second, engine assembly typically needs to be completed under strict space and time constraints, demanding high efficiency and precision. However, traditional engine installation methods rely on manual operation and the use of dual lifting tools, which is not only inefficient but also prone to numerous instabilities.

[0050] Specifically, the commonly used method for adjusting the engine mounting posture is the use of two lifting devices. The two-lifting-device installation method involves manually fixing one end of the engine to the lifting device, then moving the engine to the designated position. After stabilization, another lifting device is installed manually at the other end of the engine. By using the two lifting devices together, the engine can be flipped to the desired posture, thus achieving engine flipping.

[0051] The flipping of the spreader requires manual assistance to install it onto the spreader. This process not only consumes a lot of time and manpower, but the stability and accuracy of the flipping also depend entirely on the experience and skills of the operator. It is difficult to guarantee that the expected posture and quality can be achieved every time the flipping is completed, resulting in poor reliability.

[0052] In addition, each attitude adjustment requires the reinstallation of the lifting device, which seriously affects the assembly efficiency of the engine, resulting in very low efficiency. Furthermore, the lifting device is unstable in its rotation, and the rotation angle and attitude rely entirely on manual perception, making it impossible to guarantee the required rotation attitude.

[0053] To address the problems of time-consuming, labor-intensive, inefficient, and unstable engine rotation processes, an electric lifting and rotating machine for auxiliary engine installation has been developed. This machine aims to improve the efficiency and stability of engine installation through automation technology.

[0054] This equipment boasts advantages such as high flipping efficiency, stability, reliability, and the ability to accommodate various flipping angles. Its 360° flipping function can meet the needs of engines in different orientations while ensuring flipping quality. Its X and Z directional mobility design allows the equipment to adapt to flipping and engine placement at different heights and positions, significantly improving subsequent installation efficiency.

[0055] Furthermore, the device's tilting angle is precisely controlled, replacing manual perception and ensuring stability and reliability, resulting in more consistent and reliable outcomes. The clamping and placement of the engine also eliminates the need for manual installation or disassembly, further improving work efficiency.

[0056] Through these technological innovations, the electric lifting and tilting machine has advantages such as high tilting efficiency, stability and reliability, and the ability to meet different tilting angles, bringing revolutionary changes to the aviation manufacturing industry.

[0057] In summary, against the backdrop of the above research, in-depth analysis and improvement exploration were conducted on aero-engines, and it was found that: traditional lifting devices lack the necessary adjustment and positioning functions, making it difficult to achieve precise angle adjustments during the flipping process. Using dual lifting devices for engine flipping requires precise coordination between the two devices, and any lack of coordination between the two can lead to deviations in the flipping attitude. Furthermore, the flipping process is highly dependent on the experience and skills of the operators, and the subjectivity and inconsistency of manual operation are the main reasons why the flipping attitude is difficult to standardize.

[0058] Therefore, this technical solution proposes a novel electric lifting and tilting machine for assisted installation of aero engines. This solution utilizes X and Z directional movement mechanisms to adapt to tilting requirements at different heights and positions, improving installation efficiency. Furthermore, the device controls the tilting angle and features 360° rotation to ensure precision and stability, eliminating the need for manual assistance and significantly enhancing the level of assembly automation, thereby enabling multi-angle attitude adjustment of the engine.

[0059] The technical solutions provided by the various embodiments of this application are described below with reference to the accompanying drawings.

[0060] like Figure 1 As shown, Figure 1 This is an assembly drawing of the electric lifting and tilting machine during operation. The lifting and tilting mechanism includes a directional movement mechanism 1, a Y-axis rotation mechanism 2, a Z-axis rotation mechanism 3, a C-type ring gripper mechanism 6, and an HMI (human-machine interface).

[0061] Among them, the electric lifting and tilting machine requires operators to fix the C-clamp 6 to the intermediate brake of the engine during the installation of the aircraft engine. The C-clamp 6 is a special clamp designed to firmly grasp the key parts of the engine in order to perform the tilting operation.

[0062] Next, after the operator secures the C-clamp, they use the operating equipment to flip the C-clamp to achieve the overall flipping of the engine. This step is a crucial part of the engine installation process, ensuring that the engine can be flipped to the required position.

[0063] In addition, after the engine is flipped to a certain position, it is adjusted using the directional movement mechanism 1 to position the engine in a precise gripping position. This step requires the Z-direction lifting mechanism 4 and the X-direction movement mechanism 5 to work together to ensure that the engine can be accurately moved in the vertical and horizontal directions. After the engine is in position, the C-shaped ring gripper 6 on the Z-axis rotation mechanism 3 will perform positioning and clamping operations. The C-shaped ring gripper 6 on the Z-axis rotation mechanism 3 is a specially designed clamp to ensure that the engine is stable during the flipping process and will not slip or shift.

[0064] Through the coordinated operation of the Y-axis rotation mechanism 2 and the Z-axis rotation mechanism 3, the engine's attitude is further adjusted until the required precise position is achieved. The Y-axis rotation mechanism 2 is responsible for adjusting the engine's attitude in the horizontal plane, while the Z-axis rotation mechanism 3 is responsible for adjusting the engine's attitude in the vertical plane.

[0065] In addition, the engine is adjusted to the required posture using the Y-axis rotation mechanism 2 and the Z-axis rotation mechanism 3. After the engine posture adjustment is completed, the engine is moved to the final placement position again using the directional movement mechanism 1 to complete the placement. This step ensures that the engine can be safely and accurately placed in the predetermined installation position.

[0066] Throughout the process, the automation and precise control of the electric lifting and tilting machine significantly improved the efficiency and safety of engine installation. By reducing manual operation, operational risks were lowered, while also increasing the repeatability and reliability of the installation process. The application of this equipment is of great significance for improving the automation level of aero-engine assembly lines.

[0067] like Figure 2 As shown, Figure 2 This is a front view of the electric lifting tilting machine, which defines the X, Y, and Z directions. First, the tilting machine's upright column is a long, rectangular structure perpendicular to the ground. As the supporting frame of the entire equipment, the upright column is the vertical support structure of the electric lifting tilting machine, providing stability and load-bearing capacity to withstand the weight of the engine and the dynamic load generated during the tilting process.

[0068] Specifically, the lifting guide sliders 7 are key components in the electric lifting and tilting machine. They move up and down along the column to achieve vertical adjustment of the equipment. These lifting guide sliders 7 are mounted on the guide rail system to ensure smooth and linear lifting movements. The guide rail design typically uses wear-resistant materials to reduce friction on the lifting guide sliders 7. The lifting guide sliders 7, in conjunction with the lead screw 8, are driven by the servo motor 14 to achieve precise height control.

[0069] Furthermore, the Y-axis rotation mechanism 2 is a key component in the electric lifting and tilting machine, enabling the engine to rotate at multiple angles in the horizontal plane. Its ingenious design, mounted on the X-direction moving mechanism 5, ensures the flexibility and precision of the equipment during tilting operations. The Y-axis rotation mechanism 2 is connected to the mounting plate of the X-direction moving mechanism 5 via a translational mounting positioning ring 16. This connection method not only ensures the stable positioning of the Y-axis rotation mechanism but also allows it to move horizontally in the X direction to accommodate engines in different positions.

[0070] Furthermore, the core component of the Y-axis rotation mechanism 2 is the Y-axis rotary motor 20, which is mounted on the hollow Y-axis rotation platform and provides the necessary power for the entire rotation mechanism. The selection and control of the motor are crucial for achieving smooth and precise rotation. Therefore, the Y-axis rotary motor 20 must have high torque and high speed control capabilities to ensure that the rotation platform can be precisely positioned and rotated at a predetermined angle.

[0071] Meanwhile, a human-machine interface is installed on the control console at the bottom of the lifting and tilting machine. The human-machine interface is placed on the side of the Y-axis rotation mechanism and the Z-axis rotation mechanism. The human-machine interface is connected to the Z-axis lifting mechanism 4, the X-axis moving mechanism 5, the Y-axis rotation mechanism 2 and the Z-axis rotation mechanism 3 through control lines. It is used to control the movement of the electric lifting and tilting machine and the C-shaped ring gripper mechanism 6. The Y-axis hollow rotation platform 23 is connected to the Y-axis rotation motor 20. This platform adopts a hollow design. The Y-axis rotation motor 20 is connected to the side or top of the hollow rotation platform 23. This layout optimizes space utilization and ensures the stability of the rotation center and the uniformity of the rotation movement.

[0072] A rotary positioning ring 22 is also provided on the rotating base. The function of this component is to fix the Z-axis rotating mechanism 3 and ensure the precise alignment of the Z-axis rotating mechanism when it rotates vertically. The connection between the rotary positioning ring 22 and the Z-axis rotating mechanism 3 is achieved through precise mechanical design. It not only provides stable support, but also allows the Z-axis rotating mechanism to rotate freely on the Y-axis rotating platform, thereby realizing the attitude adjustment of the engine in three-dimensional space.

[0073] In summary, the design and function of the Y-axis rotation mechanism 2 are crucial to the overall performance of the electric lifting and tilting machine. It not only provides precise and stable rotational capability but also, through close integration with the X-axis movement mechanism 5, achieves precise rotation and positioning of the engine in the horizontal plane. This design not only improves operational efficiency but also reduces potential errors during operation through precise control, ensuring operational safety and high-quality standards for engine installation. Through this sophisticated mechanical design and advanced control technology, the Y-axis rotation mechanism provides strong technical support for the automated installation of aero-engines, significantly enhancing the automation level and ease of operation of the entire installation process.

[0074] Among them, such as Figure 3 As shown, Figure 3 This is a side view of the directional movement mechanism 1 inside the electric lifting and tilting machine. The directional movement mechanism 1 of the electric lifting and tilting machine allows the equipment to move in the vertical Z-axis and horizontal X-axis directions to adapt to the needs of engine tilting and placement at different heights and positions. The directional movement mechanism 1 includes a Z-axis lifting mechanism 4 and an X-axis movement mechanism 5.

[0075] In some embodiments, the directional movement mechanism 1 includes a Z-direction lifting mechanism 4 and an X-direction movement mechanism 5. The Z-direction lifting mechanism 4 and the X-direction movement mechanism 5 are the core components in the electric lifting and tilting machine that enable vertical and horizontal movement. They work together to adapt to the needs of engine tilting and placement at different heights and positions.

[0076] Specifically, the Z-direction lifting mechanism 4 consists of a tilting machine column 10, a lifting servo motor 9, a lead screw 8, a lifting guide rail slider 7, and a lead screw connecting seat 11. The tilting machine column 10, as a supporting structure, must possess sufficient strength and rigidity to withstand the weight of the engine and the forces generated during the tilting process.

[0077] In addition, the lifting servo motor 9 provides smooth lifting power through precise control, the lead screw 8 converts the rotational motion of the motor into linear motion, the lifting guide slider 7 moves up and down along the tilting machine column 10 to realize the vertical adjustment of the equipment, and the lead screw 8 connecting seat ensures the stability and load-bearing capacity of the lifting mechanism.

[0078] In addition, the Z-direction lifting mechanism 4 is located on the base of the bottom center line of the lifting and tilting machine, and the lifting servo motor 9 is driven by the lead screw 8 and the lifting guide rail slider 7 moves vertically along the tilting machine column.

[0079] Furthermore, the Z-direction lifting mechanism 4 is designed to allow the entire tilting machine to move in the height direction. By moving it to different positions, it can not only ensure sufficient tilting space but also allow the engine to grab and place objects at different heights. The lifting servo motor 9 installed on it is the power source.

[0080] The X-direction moving mechanism 5 consists of a mounting plate 13, a lifting plate 12, a felt gear 18, a helical gear rack 19, a horizontal moving guide rail slider 17, a translational servo motor 14, a translational mounting and positioning ring 16, and a limit switch 15. The mounting plate 13 serves as the base, and the lifting plate 12 connects to the Z-direction lifting mechanism 4 to achieve vertical movement. The translational servo motor provides power for the equipment's movement in the X direction, and the helical gear rack cooperates with the felt gear 18 to achieve smooth horizontal movement. The horizontal moving guide rail slider 17 moves along the guide rail, ensuring the stability and accuracy of horizontal movement. The translational mounting and positioning ring 16 is used to fix and position the X-direction moving mechanism 5, and the limit switch 15 controls the travel in the X direction to prevent the equipment from exceeding its range of motion.

[0081] In addition, the X-direction moving mechanism 5 is connected to the lifting guide rail slider 7 and lead screw 8 of the Z-direction lifting mechanism 4 through the lifting plate 12. The horizontal moving guide rail slider 17 is mounted on the mounting plate 13 and works in coordination with the translation servo motor 14 to realize movement in the X-axis direction.

[0082] Furthermore, the function of the X-direction moving mechanism 5 is to enable the entire tilting machine to move horizontally, and to enable the engine to grasp and place in different horizontal directions by moving to different positions.

[0083] Both mechanisms operate based on servo motor control and a mechanical transmission system. The Z-axis lifting mechanism uses a servo motor to drive a lead screw for vertical lifting; the X-axis moving mechanism uses a translation servo motor to drive a helical rack and pinion for horizontal movement. The control system employs advanced servo control technology, integrating position sensors and feedback devices to achieve precise control of the directional moving mechanisms. Operators can input commands through a human-machine interface, and the control system automatically adjusts the equipment position.

[0084] The directional movement mechanism boasts advantages such as high load-bearing capacity, high-precision control, good stability, ease of maintenance, and operational safety. These characteristics make the mechanism ideal for tilting and placing heavy equipment such as aircraft engines, providing powerful functionality and flexibility for electric lifting and tilting machines.

[0085] like Figure 4 As shown, Figure 4 This is a schematic diagram of the Z-direction lifting mechanism of the electric tilting machine. The tilting machine column serves as the support for the entire equipment. The lifting servo motor and lead screw provide a smoother movement, which can effectively achieve synchronous lifting or lowering of the equipment. The lifting guide rail slider and lead screw connecting seat are equipped with (5) X-direction moving mechanism to drive the mechanism to move.

[0086] The lifting plate is connected to the lifting guide rail and lead screw connecting seat on the Z-direction lifting mechanism 4 to achieve up and down movement; the translation servo motor provides power for the equipment to move in the X direction, and the limit switch on it controls the stroke in the X direction to protect the mechanism and prevent collisions; considering the long-term heavy load and adjustment movement of the helical gear rack, felt gears are used to reduce tooth surface wear and improve service life.

[0087] In some embodiments, the Y-axis rotation mechanism 2 is connected to the translation base of the X-direction moving mechanism 5, enabling it to work in conjunction with the X-direction moving mechanism 5. The translation mounting positioning ring 16 on the translation base provides a precise mounting position for the Y-axis rotation mechanism 2, ensuring that the rotation mechanism can smoothly rotate the engine in the horizontal plane.

[0088] During operation, the Y-axis rotary motor 20 drives the Y-axis hollow rotary platform 23 to rotate, thereby adjusting the engine's attitude in the horizontal direction. The rotating base 21 and the rotary positioning ring 22 together ensure the stability and accuracy of the rotary platform. By precisely controlling the Y-axis rotary motor 20, the engine can be accurately positioned to meet different installation requirements.

[0089] The Y-axis rotation mechanism 2, through its close integration with the X-direction movement mechanism 5, improves the efficiency of engine installation and reduces potential errors during operation through precise control, thus ensuring operational safety.

[0090] In some embodiments, the Z-axis rotation mechanism 3 is responsible for realizing the rotation of the motor of the electric lifting and tilting machine in the vertical plane, that is, the rotation about the Z-axis. The Z-axis rotation mechanism 3 is precisely positioned and installed through the rotation positioning ring of the Y-axis rotation mechanism 2, ensuring the coordination and precise alignment between the Z-axis rotation mechanism and the Y-axis rotation mechanism.

[0091] The core components of the Z-axis rotation mechanism 3 include the Z-axis rotation motor 25 and the Z-axis hollow rotary table 26. The Z-axis rotation motor 25 is the power source that drives the rotation of the entire mechanism. The Z-axis hollow rotary table 26 of the Z-axis rotation mechanism 3 allows air pipes, cables or other connectors to be transmitted through the central hole during rotation, enhancing the practicality and flexibility of the structure.

[0092] The Z-axis rotation mechanism 3 is mounted on the Y-axis rotation mechanism 2 in a superimposed structural design, which allows the engine to achieve vertical rotation on the basis of the horizontal rotation provided by the Y-axis rotation mechanism, so that the engine can be precisely placed in the required spatial position and attitude.

[0093] During operation, the engine can rotate around the Z-axis by controlling the Z-axis rotary motor, achieving precise positioning at different heights and directions. Simultaneously, the rotary positioning ring of the Y-axis rotary mechanism ensures the stability and accuracy of the Z-axis rotary mechanism during rotation. This design not only improves the efficiency of engine installation but also reduces potential errors during operation through precise control, ensuring operational safety.

[0094] Furthermore, the Z-axis rotation mechanism is designed with ease of maintenance and adjustment in mind. All key components are easily accessible for regular inspection and maintenance. The control system can be easily debugged via a human-machine interface to adapt to different working conditions and requirements.

[0095] In summary, the combined use of the Z-axis rotation mechanism 3 and the Y-axis rotation mechanism 2 provides an efficient and stable attitude adjustment solution for the electric lifting and tilting machine. This design not only improves the efficiency and safety of engine installation, but also achieves precise engine positioning through precise control, meeting the high requirements for accuracy and stability during aero-engine installation.

[0096] In some embodiments, the C-ring gripper mechanism 6 is mounted on the hollow rotary table 26 of the Z-axis of the Z-axis rotating mechanism 3. The C-ring gripper mechanism 6 controls the gripper blocks to clamp the C-shaped clamp through the clamping cylinder 37. The C-ring gripper mechanism 6 achieves precise positioning of the engine by extending the positioning pin 34 through the pin cylinder 33. The C-ring gripper mechanism 6 is connected to the Z-axis rotating mechanism 3 through the gripper support plate 30.

[0097] Specifically, the C-ring gripper mechanism 6 is a key mechanical component in the electric lifting and tilting machine used for precise clamping and positioning of the engine. This mechanism is mounted on the hollow rotary table 26 of the Z-axis rotation mechanism 3. Utilizing the central through hole of the hollow rotary table, the C-ring gripper mechanism 6 can maintain stable clamping while the engine rotates around the Z-axis.

[0098] The C-ring gripper mechanism 6 controls the clamping force of the gripper block on the C-clamp through the clamping cylinder 37. The operation of the clamping cylinder 37 enables the gripper block to firmly clamp the C-clamp of the engine, ensuring the stability and safety of the engine during flipping and rotation. The precise control of the cylinder ensures the uniformity and adaptability of the clamping force to accommodate engines of different sizes and shapes.

[0099] Furthermore, the C-ring gripper mechanism 6 also includes a pin cylinder 33, which achieves precise engine positioning by extending a positioning pin 34. The positioning pin 34 inserts into a specific position in the engine C-clamp, working in conjunction with the clamping action of the gripper blocks to ensure the accurate position and orientation of the engine on the tilting machine. This positioning mechanism is crucial for achieving high-precision engine installation.

[0100] The connection between the C-type ring gripper mechanism 6 and the Z-axis rotation mechanism 3 is achieved through the gripper support plate 30. As a structural component, the gripper support plate 30 not only supports the weight of the gripper mechanism but also transmits the power to the clamping cylinder and the pin cylinder, ensuring the stable operation of the gripper mechanism.

[0101] Overall, the C-ring gripper mechanism 6, through its close integration with the Z-axis rotation mechanism 3, provides stable clamping and precise positioning during engine installation and rotation. This design not only improves the efficiency of engine installation but also reduces potential errors during operation through precise control, ensuring operational safety and high-quality standards for engine installation. With the cooperation of an automated control system, the C-ring gripper mechanism 6 achieves a high degree of automation and intelligent operation.

[0102] In some embodiments, the lifting guide slider 7 and the lead screw connecting seat 11 of the lifting plate Z-axis lifting mechanism 4 are precisely matched to achieve the function of vertical movement. This vertical movement is accomplished by the rotation of the lead screw 8 controlled by the lifting servo motor 9. The linear motion of the lead screw 8 drives the lifting guide slider 7, thereby pushing the lifting plate to move precisely along the Z-axis. The design of the lifting plate 12 must ensure its structural strength and stability to support the weight of the engine and achieve smooth vertical adjustment.

[0103] Specifically, in the X direction, the translation servo motor 14 provides power to the device, driving the mounting plate 13 to move horizontally along the X-axis. This horizontal movement capability allows the device to adapt to engines in different positions, increasing operational flexibility. The precise control capability of the translation servo motor 14 ensures the movement accuracy of the device in the X direction, meeting the requirements for precise engine placement.

[0104] To ensure the safe operation of the equipment and prevent collisions due to excessive travel, the translation servo motor 14 is equipped with a limit switch. The limit switch 15 is automatically triggered when the equipment reaches the limit position in the X direction, cutting off the power and stopping the equipment from moving further, thereby protecting the safety of the equipment and the operator.

[0105] Considering the use of helical gear racks under prolonged heavy loads and frequent adjustments, a felt gear 18 was specifically incorporated into the design. The felt gear 18 meshes with the helical gear rack 19, effectively reducing friction and wear between the tooth surfaces and improving the lifespan and reliability of the transmission system. The use of felt material also helps absorb shock and reduce noise, further enhancing the equipment's operating performance.

[0106] Furthermore, the helical rack and pinion design allows for the carrying of large loads while maintaining a precise gear ratio, which is crucial for ensuring stable and controllable movement of the equipment in the X direction. The entire transmission system is designed with durability and maintainability in mind, ensuring long-term stable operation of the equipment.

[0107] In summary, the coordinated operation of the lifting platform 12 and the Z-axis lifting mechanism 4, along with the precise control of the X-axis moving mechanism 5, enables the electric lifting and tilting machine to achieve precise adjustment and placement of the engine in both vertical and horizontal directions. These designs not only improve operational efficiency but also ensure operational safety and equipment reliability through the introduction of safety features. Through a carefully designed mechanical transmission system and an advanced control system, the electric lifting and tilting machine provides an efficient, stable, and safe solution for the installation of aero engines.

[0108] like Figure 5 , Figure 6 and Figure 7 As shown, Figure 5 , Figure 6 and Figure 7 This is a breakdown diagram of the moving mechanism of the electric tilting machine. The Y-axis rotation mechanism 2 is the key component in the electric lifting tilting machine that enables the engine to rotate at multiple angles in the horizontal plane. It consists of components such as the translation base 24, the Y-axis hollow rotating platform 23, the rotating base 21, the rotating positioning ring 22, and the Y-axis rotating motor 20, which work together to provide precise and stable rotation.

[0109] The translation base serves as the foundation for the Y-axis rotation mechanism 2. It achieves precise positioning and installation through its connection with the translation mounting ring on the X-axis movement mechanism 5. This design allows the Y-axis rotation mechanism to move horizontally in sync with the X-axis movement of the equipment, ensuring overall equipment coordination and operational consistency.

[0110] The Y-axis rotary motor 20 is the core component providing rotational power, and its selection and control are crucial for achieving smooth and precise rotation. The motor's precise control capability ensures that the Y-axis rotary platform 23 can be accurately positioned and rotated at predetermined angles, meeting the stringent precision requirements during engine installation.

[0111] The hollow Y-axis rotary platform 23 is another key part of the Y-axis rotary mechanism 2. Its turntable adopts a hollow structure design. The Y-axis servo motor 20 is connected to the side of the hollow Y-axis rotary platform 23. This layout optimizes space utilization and ensures the stability of the rotation center and the uniformity of the rotation action.

[0112] The rotating base 21 provides stable support for the hollow rotating platform along the Y-axis. It is typically made of high-strength materials to ensure stability and load-bearing capacity during engine rotation. The design of the rotating base also needs to consider its connection method with the translational base to achieve a robust and harmonious overall structure.

[0113] The rotary positioning ring 22 is a key component that ensures the precise positioning of the Z-axis rotation mechanism. It works in conjunction with the translational mounting positioning ring 16 to ensure the accurate alignment of the rotary platform during rotation. The design of the positioning ring needs to take into account its compatibility with the rotary platform and motor, as well as its durability in repeated use.

[0114] The design of the Y-axis rotation mechanism 2 comprehensively considers work efficiency, precision, rigidity, and cost-effectiveness. This mechanism can complete engine attitude adjustment in a short time, improving overall installation efficiency. High precision ensures accurate engine positioning during installation, meeting the high precision requirements of aero-engine installation. High rigidity guarantees structural stability during rotation, preventing positioning errors caused by deformation or vibration. High cost-effectiveness demonstrates that the mechanism meets technical requirements while also offering reasonable cost benefits.

[0115] In summary, the design and function of the Y-axis rotation mechanism 2 are crucial to the overall performance of the electric lifting and tilting machine. It not only provides precise and stable rotation capabilities, but also meets the high requirements for efficiency, accuracy and stability during the installation of aero-engines through innovative hollow structure design and precise servo motor control.

[0116] like Figure 8 , Figure 9 As shown, Figure 8, Figure 9 This is a schematic diagram of the rotating mechanism of the electric tilting machine. The Z-axis rotating mechanism 3 is a key mechanical component in the electric lifting tilting machine that enables the engine to rotate at multiple angles in the vertical plane. It consists of a protective cover, a rotating support, a Z-axis rotating motor, a Z-axis hollow rotating table, and a C-shaped ring gripper mechanism 6, which work together to provide precise vertical rotation.

[0117] In one embodiment, the protective cover 27 covers the outside of the Z-axis rotation mechanism 3; the protective cover 27 is connected to the rotation bracket 28 to ensure that the protective cover 27 remains in a fixed position when the Z-axis hollow rotary table 26 rotates, and the protective cover 27 surrounds the Z-axis hollow rotary table.

[0118] The protective cover 27 is the first line of defense for the Z-axis rotary mechanism. Its design aims to prevent external dust, hard sand particles, and other impurities from entering the mechanism. This protection is crucial for reducing wear on internal parts, extending equipment lifespan, and maintaining the long-term stable operation of the rotary mechanism. The protective cover is typically made of durable materials, ensuring sufficient strength to withstand external impacts while also facilitating maintenance and cleaning.

[0119] Specifically, the rotating bracket 28 is a key structure supporting the Z-axis rotating mechanism and enabling its positioning. It is precisely positioned and installed via a rotating positioning ring on the Y-axis rotating mechanism 2, ensuring that the Z-axis rotating mechanism can work synchronously with the Y-axis rotating platform, achieving precise engine rotation in the vertical plane. The design of the rotating bracket needs to consider compatibility with the Y-axis rotating mechanism and sufficient rigidity to withstand the torque generated during engine rotation.

[0120] like Figure 10 As shown, Figure 10 This is a split diagram of the Z-axis rotation mechanism of an electric tilting machine according to this application. The Z-axis rotation motor 25 is the core power source driving the Z-axis rotation mechanism. It must have high torque and high speed control capabilities to ensure that the turntable can smoothly and accurately reach the required rotation angle. Precise control of the motor is crucial for achieving accurate motor positioning, while also considering the motor's heat dissipation and long-term operational reliability.

[0121] The hollow Z-axis rotary table 26 is the main part of the Z-axis rotation mechanism. Its hollow design not only reduces the overall weight but also provides space for various pipelines and air pipes on the engine to pass through. The Z-axis rotation motor is connected to the side or top of the hollow rotary table. This layout optimizes space utilization while ensuring the stability of the rotation center and the uniformity of the rotational motion.

[0122] like Figure 11 As shown, Figure 11This is a schematic diagram of the C-ring gripper mechanism of the electric tilting machine. The C-ring gripper mechanism 6 plays a crucial role in the electric lifting tilting machine, its main function being to achieve precise positioning and clamping during the engine tilting process. This mechanism ensures that the engine is firmly fixed in the proper position through a series of precise movements, providing the necessary stability and safety for subsequent tilting operations.

[0123] Specifically, the core components of the mechanism include a gripper support plate 29, a positioning pin 34, a gripper block 36, a cylinder mounting plate 35, a clamping cylinder 37, a pin cylinder 33, a connecting block 39, and a clamping rotating block 38. The gripper support plate 29, as the basic structure, is connected to the Z-axis hollow rotary table 26 on the Z-axis rotating mechanism, allowing the C-ring gripper mechanism 6 to rotate with the engine, ensuring the synchronization of the clamping action.

[0124] In addition, the clamping cylinder 37 is responsible for driving the movement of the gripper blocks. By controlling the extension and retraction of the cylinder, the C-clamp of the engine can be clamped or released. The gripper blocks include a first gripper 30, a second gripper 31, and a third gripper 32. The design of the gripper blocks must ensure that the force can be evenly distributed during the clamping process to avoid damage to the engine, while providing sufficient friction to prevent slippage.

[0125] In one embodiment, the positioning pin 34 is a key component for achieving precise positioning. Driven by a pin cylinder, it can be inserted into or withdrawn from the positioning hole of the engine C-clamp. When the positioning pin 34 is inserted into the positioning hole, it works in conjunction with the clamping action of the gripper block to ensure the accurate position of the engine on the tilting machine and provide a stable support point for the engine.

[0126] The connecting block 39 and the clamping rotating block 38 are responsible for transmitting power and adjusting the position of the gripper blocks to accommodate engines of different sizes. This design allows the C-ring gripper mechanism to have excellent adaptability and flexibility, meeting the installation requirements of different engine models.

[0127] The C-ring gripper mechanism 6 is designed with ease of operation, safety, and precision in mind. In conjunction with an automated control system, the C-ring gripper mechanism 6 achieves rapid response and precise control, significantly improving engine installation efficiency. Furthermore, this mechanism's design also considers ease of maintenance and debugging, ensuring long-term stable operation of the equipment.

[0128] In summary, the C-ring gripper mechanism 6, with its precise positioning and clamping functions, provides a reliable and efficient engine securing solution for electric lifting and tilting machines. This design not only improves operational efficiency but also reduces potential errors during operation through precise control, ensuring operational safety and high-quality standards for engine installation.

[0129] like Figure 12 As shown, Figure 12 This is a breakdown diagram of the C-ring gripper mechanism in an electric tilting machine. The C-ring gripper mechanism 6 is a crucial component in the electric tilting machine for precise clamping and positioning of the engine. The efficient operation of this mechanism relies on its close cooperation with the Z-axis rotation mechanism 3. The gripper support plate 29, as a key part of the C-ring gripper mechanism 6, is directly connected to the hollow Z-axis rotary table on the Z-axis rotation mechanism 3, ensuring that the gripper mechanism rotates synchronously with the engine's Z-axis rotation, achieving precise clamping at multiple angles.

[0130] In one embodiment, the gripper design employs a clamping cylinder 37 to control the movement of the gripper blocks. Through the extension and retraction of the cylinder, the gripper blocks can firmly clamp the C-clamp of the engine. This design not only provides strong clamping force but also allows for fine-tuning of the clamping force by precisely controlling the air pressure of the cylinder, adapting to engines of different sizes and shapes, and ensuring the stability and safety of the engine during flipping.

[0131] Specifically, another key action of the gripper mechanism is the insertion of the positioning pin 34. The pin cylinder 33 is responsible for driving the extension and retraction of the positioning pin. When the positioning pin 34 is inserted into the positioning hole of the C-clamp, it locks the engine's position, preventing displacement during tilting or rotation. The precision of this action is crucial for ensuring accurate alignment of the engine during installation, and also improves the overall operating efficiency of the tilting machine.

[0132] Furthermore, the C-ring gripper mechanism 6, through an automated control system, allows the actions of the clamping cylinder 37 and the pin cylinder 33 to be synchronized and coordinated with the rotation of the Z-axis rotating mechanism, achieving an automated clamping and positioning process. This automated operation not only reduces manual intervention and the possibility of operational errors, but also greatly improves the efficiency and repeatability of engine installation.

[0133] The C-shaped ring gripper mechanism 6 is mounted on the hollow rotary table 26 of the Z-axis rotation mechanism 3 to clamp the engine in a C-shaped clamp. The C-shaped ring gripper mechanism 6 is connected to the rotating bracket 28 of the Z-axis rotation mechanism 3 and is located at the center of the hollow rotary table 26. The first gripper 30, second gripper 31, and third gripper 32 of the C-shaped ring gripper mechanism 6 are controlled by a clamping cylinder 37 to ensure the engine remains stable and does not slip during rotation. The C-shaped ring gripper mechanism 6 controls a positioning pin 34 via a pin cylinder 33, which is inserted into the positioning hole of the C-shaped clamp to achieve precise engine positioning. A gripper support plate 30 connects the first gripper 30, second gripper 31, third gripper 32, and the Z-axis rotation mechanism 3 to ensure the grippers remain stable during Z-axis rotation.

[0134] Meanwhile, the C-shaped ring gripper mechanism 6 is controlled by a human-machine interface. The operator inputs commands through this interface to realize the automatic clamping, loosening, and positioning of the gripper, ensuring precise fixation and rotation of the engine. The rotating bracket 28 of the Z-axis rotating mechanism 3 is fixed above the Y-axis rotating mechanism 2 to support the Z-axis rotating mechanism (3).

[0135] In general, the Y-axis rotary motor 20 is mounted on the Y-axis hollow rotary platform; the Z-axis hollow rotary table 26 is mounted on the output end of the Z-axis rotary motor 25, allowing the engine's C-ring gripper mechanism 6 to pass through the center of the Z-axis hollow rotary table 26; the Z-axis rotary mechanism 3 is connected to the Y-axis rotary platform 23 via a rotary positioning ring 22; and the C-ring gripper mechanism 6 is mounted on the Z-axis hollow rotary table 26.

[0136] In one embodiment, the gripper support plate 29 of the C-ring gripper mechanism 6 is aligned with the central axis of the Z-axis hollow rotary table 26 so that the gripper applies force evenly to the C-ring gripper mechanism 6 of the engine.

[0137] The gripper support plate 29 is connected to the rotating bracket 28 of the Z-axis rotating mechanism 3 via the Z-axis hollow rotating state 26, allowing the C-shaped ring gripper mechanism 6 to rotate together with the Z-axis hollow rotating table 26.

[0138] Furthermore, the Z-axis hollow rotary table 26 is mounted on the rotary support 28 of the Z-axis rotary mechanism 3, and the Z-axis rotary motor is mounted on the Z-axis hollow rotary table to drive the Z-axis hollow rotary table 26 to rotate around the Z-axis.

[0139] The Z-axis hollow rotary table 26 is designed with a hollow structure; the C-shaped ring gripper mechanism 6 is installed at the bottom of the Z-axis hollow rotary table 26 and is connected to the rotary table through the gripper support plate 29 to realize the clamping and attitude adjustment of the engine.

[0140] In one embodiment, the Z-axis hollow rotary table 26 is a key component in the electric lifting and tilting machine for achieving precise engine attitude adjustment. Its design is cleverly aligned with the rotation axis of the Y-axis rotating mechanism, ensuring accuracy and consistency when performing vertical and horizontal rotation operations on the engine.

[0141] Specifically, this alignment method allows the engine to rotate around both the Y and Z axes simultaneously, enabling complex spatial attitude adjustments. Alignment of the central axis of the hollow rotary table means that rotational torque can be evenly distributed, reducing additional stress and potential errors caused by misalignment. Furthermore, the hollow design provides pathways for necessary pipelines and cables on the engine, making the entire rotating mechanism more compact and efficient.

[0142] Through this precise axis alignment, the Z-axis hollow rotary table 26 not only improves the efficiency of engine installation and positioning, but also ensures stability and safety throughout the entire flipping process.

[0143] In summary, the design and function of the C-ring gripper mechanism 6 are crucial to the overall performance of the electric lifting and tilting machine. It not only provides precise and stable gripping capability but also, through its close integration with the Z-axis rotation mechanism 3, enables precise rotation and positioning of the engine in the vertical plane. This design not only improves operational efficiency but also reduces potential errors during operation through precise control, ensuring operational safety and high-quality standards for engine installation. Through this sophisticated mechanical design and advanced control technology, the C-ring gripper mechanism provides strong technical support for the automated installation of aero-engines.

[0144] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
