Description

Technical Field

[0001] This utility model belongs to the field of aircraft manufacturing technology and relates to an equipment for forming and assembling upper and lower aircraft panels. Background Technology

[0002] In aircraft manufacturing, the forming and assembly of upper and lower panel panels is a crucial step. Traditional aircraft panel assembly equipment suffers from numerous shortcomings. For example, existing equipment struggles to adapt to variations in panel size and structure across different aircraft models, lacking flexibility and versatility. Inaccurate clamping and positioning of the panels during assembly leads to uneven gaps and substandard flatness, severely impacting the aircraft's aerodynamic performance and structural strength. Furthermore, traditional equipment has low assembly efficiency, failing to meet the ever-increasing production demands of modern aircraft manufacturing. Additionally, existing equipment performs poorly in bearing structural loads, unable to effectively guarantee panel stability during assembly, and prone to accumulating assembly errors. Therefore, there is an urgent need to design a new aircraft upper and lower panel forming and assembly equipment to overcome these shortcomings.

[0003] To overcome the shortcomings of existing technologies, people have continuously explored and proposed various solutions. For example, a Chinese patent discloses an integral wing panel structure for aircraft [Application No.: 202120529682.0]. This integral wing panel includes an integral wing skin and multiple stringers distributed on the integral wing skin. Both the stringers and the skin are composite laminate structures, formed in one piece through a co-curing process. The wing skin and wing stringers are both horizontally continuous, with no designed separation surface in the middle, making the left and right wing panels an integrated structure. However, this solution is not suitable for panel assembly and still suffers from poor performance in bearing structural loads, failing to effectively guarantee the stability of the panel during assembly, and easily leading to the accumulation of assembly errors.

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] like Figure 1-4 As shown, an equipment for forming and assembling upper and lower aircraft panels includes a panel main frame 1. An adjustable modular pressure plate clamp 2 is provided below the panel main frame 1. The panel main frame 1 includes a top frame plate 3, a central cross frame plate 4, and a bottom support connector 5. A load-bearing reinforcing pad 6 is provided on the top of the top frame plate 3. A pressure plate 7 is installed between the bottom support connector 5 and the adjustable modular pressure plate clamp 2.

[0026] In this embodiment, the adjustable modular pressure plate clamp 2 can be flexibly adjusted according to the actual situation of the wall panel main frame 1 to ensure effective clamping and positioning of the wall panel main frame 1. The various components of the wall panel main frame 1 cooperate with each other. The load-bearing reinforcing pad 6 is used to bear the structural load and maintain overall stability, providing a stable foundation for the molding and assembly of the wall panel. The pressure plate 7 plays the role of transmitting pressure and assisting clamping between the bottom support connector 5 and the adjustable modular pressure plate clamp 2.

[0027] Combination Figure 1-4As shown, the adjustable modular pressure plate clamp 2 includes several clamp fixing base frames 8 disposed below the wall panel main frame 1. The clamp fixing base frames 8 are provided with fixing frames 9. The fixing frames 9 are provided with clamping members 10 at both ends that clamp the wall panel main frame 1. The fixing frames 9 are provided with a pressure plate arc-shaped pressure member 11 in the middle.

[0028] Specifically, the fixture fixing base frame 8 provides a stable support foundation for the entire fixture, and the fixing frame 9 serves to connect and bear the clamping member 10 and the pressure plate arc-shaped pressure member 11. The clamping member 10 achieves the initial positioning and fixing of the wall panel main frame 1 by clamping it, while the pressure plate arc-shaped pressure member 11 applies pressure to the pressure plate 7 to ensure that the pressure plate 7 can evenly press the wall panel main frame 1.

[0029] The clamping member 10 includes clamping and fixing seats 12 disposed at both ends of the fixing frame 9. A hydraulic rod is provided between the clamping and fixing seats 12 and the fixing frame 9. A reinforcing rib 13 is provided on the clamping and fixing seats 12.

[0030] In this embodiment, the hydraulic rod allows the clamping fixing seat 12 to flexibly approach or move away from the wall panel main frame 1, thereby achieving clamping of wall panel main frames 1 of different sizes and improving the adaptability of the fixture. The clamping fixing seat 12 is provided with reinforcing ribs 13, which enhance the structural strength of the clamping fixing seat 12, enabling it to withstand greater force during clamping and ensuring the reliability of clamping.

[0031] The pressure plate arc-shaped pressure application component 11 includes an arc-shaped support frame 14 mounted on a fixed frame 9. The arc-shaped support frame 14 is provided with a plurality of central pressure plate top blocks 15. A hydraulic rod is provided between the central pressure plate top blocks 15 and the arc-shaped support frame 14. The arc-shaped support frame 14 is also provided with a transition end pressure plate top block 16. The transition end pressure plate top block 16 and the central pressure plate top blocks 15 are staggered. A hydraulic rod is provided between the transition end pressure plate top block 16 and the arc-shaped support frame 14.

[0032] In this embodiment, the hydraulic rod can push the middle pressure plate top block 15 to press the arc-shaped surface of the pressure plate 7, thereby applying pressure evenly to the pressure plate 7 and ensuring that the main frame 1 of the wall panel is subjected to uniform clamping force during assembly. The arc-shaped support frame 14 is also provided with a transition end pressure plate top block 16, which is staggered with the middle pressure plate top block 15. A hydraulic rod is provided between the transition end pressure plate top block 16 and the arc-shaped support frame 14. The transition end pressure plate top block 16 is used to press the transition surface of the pressure plate 7 and works in cooperation with the middle pressure plate top block 15 to further ensure the uniformity of the force on the pressure plate 7 and improve the assembly quality.

[0033] The central cross frame plate 4 includes a transverse support plate 17 and a longitudinal support plate 18, which are arranged crosswise.

[0034] In this embodiment, the cross arrangement enhances the overall rigidity of the wall panel main frame 1, enabling it to better withstand external loads and pressure during assembly, thus ensuring the stability of the wall panel. The bottom of the transverse support plate 17 and the longitudinal support plate 18 are provided with first support column feet 19, which play a role in supporting and transmitting pressure, transferring the weight and pressure of the central cross frame plate 4 to the pressure plate 7.

[0035] Combination Figure 1-2 As shown, the bottom of the transverse support plate 17 and the longitudinal support plate 18 are provided with first support column feet 19.

[0036] In this embodiment, the first support column foot 19 plays the role of supporting and transmitting pressure, transferring the weight and pressure of the central cross frame plate 4 to the pressure plate 7.

[0037] Combination Figure 1-2 As shown, the bottom support connector 5 includes a cross-connecting plate 20, and the bottom of the cross-connecting plate 20 is provided with a second support column 21. The first support column 19 and the second support column 21 respectively abut against the pressure plate 7.

[0038] In this embodiment, the first support column foot 19 plays the role of supporting and transmitting pressure, transferring the weight and pressure of the central cross frame plate 4 to the pressure plate 7.

[0039] The working principle of this utility model is as follows:

[0040] Based on the design requirements and dimensions of the upper and lower panel of the aircraft, the clamping base frame 8 of the adjustable modular pressure plate clamp 2 is installed in a suitable position, ensuring its horizontal stability. Then, the fixing frame 9 is installed on the clamping base frame 8 and its position is adjusted. Next, the clamping component 10 and the pressure plate arc-shaped pressure application component 11 are installed. The clamping fixing seat 12 is installed at both ends of the fixing frame 9 via hydraulic rods, and the arc-shaped support frame 14 is installed in the middle of the fixing frame 9 via hydraulic rods. The hydraulic rods are then adjusted to ensure they can work normally, achieving flexible clamping of the main frame 1 of the panel and uniform pressure on the pressure plate 7. During the assembly of the main frame 1 of the wall panel, the transverse support plate 17 and the longitudinal support plate 18 are cross-installed to form the central cross frame plate 4. The first support column 19 is installed, then the top frame plate 3 is installed on top of the central cross frame plate 4, and the load-bearing reinforcing pad 6 is installed. Finally, the cross connecting plate 20 is installed at the bottom of the central cross frame plate 4 to form the bottom support connecting piece 5, and the second support column 21 is installed. The assembled main frame 1 of the wall panel is placed above the adjustable modular pressure plate clamp 2, and the position is adjusted so that the first support column 19 and the second support column 21 accurately abut against the pressure plate 7.

[0041] During the assembly of the upper and lower panels of the aircraft, the hydraulic system of the adjustable modular pressure plate clamp 2 is activated. The hydraulic rod pushes the clamping fixing seat 12 to tightly clamp both ends of the main frame 1 of the panel, achieving initial positioning. Then, according to the shape of the pressure plate 7 and the requirements of the main frame 1 of the panel, the hydraulic rod pushes the middle pressure plate top block 15 and the transition end pressure plate top block 16 to apply uniform pressure to the pressure plate 7, so that the pressure plate 7 fits tightly against the main frame 1 of the panel. This ensures that the main frame 1 of the panel is subjected to uniform and stable clamping force during the assembly process. Throughout the assembly process, the load-bearing reinforcing pad 6 bears the structural load on the panel, ensuring the stability of the main frame 1 of the panel. The structure of the central cross frame plate 4 and the bottom support connector 5 works together to enhance the rigidity of the main frame 1 of the panel and effectively reduce assembly errors.
