Description

Technical Field

[0001] This utility model relates to the field of aviation component support and positioning technology, specifically a multi-axis rapid support and positioning system for large aviation components. Background Technology

[0002] In the aerospace manufacturing industry, with the increasing complexity and precision requirements of aircraft design, traditional positioning and support methods are no longer sufficient to meet the production demands of modern large aerospace components. Multi-axis rapid support and positioning systems have emerged as a key technology for solving this problem. Large aerospace components typically have complex geometries and large dimensions, such as wings, fuselage sections, and tail sections. These components require high-precision positioning and support during manufacturing and assembly to ensure the quality and performance of the final product. Traditional positioning methods usually rely on fixed fixtures and support structures, which are cumbersome and inflexible when dealing with complex shapes and large-sized components. Changing fixtures and adjusting support positions is time-consuming and labor-intensive, making it difficult to adapt to rapidly changing production demands. Multi-axis systems can be quickly adjusted according to the shape and size of different components, providing flexible support and positioning solutions. Through sophisticated control systems and sensor technology, multi-axis systems can achieve high-precision positioning, meeting the stringent tolerance requirements of large aerospace components.

[0004] The support system includes an upper cover plate and a lower cover plate, and the upper cover plate and the lower cover plate are connected at the four corners by a first steel bar.

[0005] Multiple fixing sleeves pass through between the upper cover plate and the lower cover plate;

[0006] The transmission system includes a servo motor located at the lower end of the fixed sleeve, a motion support is slidably arranged inside the fixed sleeve, a lead screw is connected to the servo motor through a coupling, and the lead screw is connected to the fixed sleeve through a ball bearing bushing.

[0007] An adaptive flexible clamp is installed on the motion support.

[0008] Preferably, the adaptive flexible clamp includes a base connected to the motion support via a connector, and a rubber suction cup is connected to the base via a ball joint.

[0009] Preferably, auxiliary components are installed at all four corners of the upper cover plate.

[0010] Preferably, the upper cover plate and the lower cover plate are respectively provided with a second steel bar, a third steel bar and a fourth steel bar.

[0011] Preferably, the motion support is provided with a slide rail.

[0012] This utility model discloses a method for using a multi-axis rapid support and positioning system for large aerospace components, comprising the following steps:

[0013] Steps: Obtaining Component Information

[0014] The geometric dimensions and positioning distance data of the workpiece or assembly component to be positioned are obtained from the CAD model and transmitted to the servo motor.

[0015] Steps: System parameter settings

[0016] Based on the workpiece's geometric information and positioning requirements, relevant parameters such as support point position, positioning speed, and clamping force are input into the system to calibrate the system's servo motor and adaptive flexible fixture, ensuring that their accuracy meets the requirements.

[0017] Steps: Support Positioning

[0018] The multi-axis control system drives the servo motor, which transmits power to the ball screw through the coupling, moving the movable support and the adaptive flexible fixture to the target position, close to the predetermined support point of the component.

[0019] Steps: Adsorption and fixation

[0020] Clamping operation: Based on the set clamping force, the adaptive flexible fixture is activated to adsorb and fix the workpiece, ensuring that it will not move during processing or assembly.

[0021] Steps: Release the support positioning

[0022] After processing or assembly is completed, release the adaptive flexible clamp to release the workpiece from its adsorption and fixation.

[0023] The multi-axis system drives the servo motor, which in turn transmits power through the coupling to the ball screw, which in turn drives the movable support and the adaptive flexible fixture back to their initial state, ready to process the next workpiece.

[0024] This invention offers the following advantages: It features a rational structure and novel design, combining an adaptive flexible fixture and a PLC control system with a support and positioning tooling platform. This transforms the multi-point positioning fixture into an adaptive flexible fixture capable of tightly fitting the workpiece, making the workpiece more stable during the support and positioning process and improving support and positioning performance. The controllable longitudinal movement of the moving support column makes the workpiece positioning process more reliable and reduces workpiece deformation. This multi-axis rapid support and positioning system for large aerospace components has wide applications in the aerospace field. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figure 1-4 A multi-axis rapid support and positioning system for large aerospace components includes a support system and a transmission system. The support system includes an upper cover plate 2 and a lower cover plate 4, which are connected at their four corners by a first steel strip 8. Multiple fixed sleeves 3 pass through the upper cover plate 2 and the lower cover plate 4. The transmission system includes a servo motor 10 located at the lower end of the fixed sleeves 3. A motion support column 6 is slidably arranged inside the fixed sleeves 3. A lead screw 13 is connected to the servo motor 10 through a coupling 12. The lead screw 13 is connected to the fixed sleeves 3 through a ball bearing sleeve 14. An adaptive flexible clamp 1 is installed on the motion support column 6. The adaptive flexible clamp 1 includes a base 19 connected to the motion support column 6 through a connector 17. A rubber suction cup 16 is connected to the base 19 through a ball joint 18. A slide rail 15 is provided on the motion support column 6.

[0032] The transmission system is driven by nine servo motors 10. To ensure that the support column assembly only moves in a straight line, slide rails 15 are provided on both sides of the moving support column 6 to ensure that the moving support column 6 only moves in a straight line up and down. The support system is mainly composed of an upper cover 2, a lower cover 4, and steel bars, which play a supporting and fixing role. The straight line up and down movement refers to the movement of the moving support column 6 in the Z-axis direction.

[0033] Auxiliary parts 7 are installed at all four corners of the top cover plate 2;

[0034] When aircraft panels are large in shape and size, a single flexible tooling platform may not meet their assembly requirements. In such cases, multiple independent tooling platforms can be connected together using auxiliary components 7 to form a larger integrated tooling platform. This modular tooling platform provides broader support and positioning capabilities, ensuring that large panels are adequately supported and precisely positioned during assembly. This approach not only meets the assembly needs of large panels but also improves the flexibility and efficiency of the assembly process, adapting to panel assembly tasks of different specifications and shapes. This modular design concept allows the tooling platform to be flexibly adjusted and expanded according to specific production needs, greatly enhancing the adaptability and efficiency of the production line.

[0040] Step 3: Support Positioning

[0041] The multi-axis control system drives the servo motor 10, which transmits power to the ball screw 13 through the coupling 12, thereby moving the movable support column 6 and the adaptive flexible clamp 1 to the target position, close to the predetermined support point of the component.

[0042] Step 4: Adsorption and fixation
