Description

Technical Field

[0001] This application relates to the field of aircraft manufacturing technology, and in particular to a wing assembly method and tooling. Background Technology

[0002] In the manufacturing process of aircraft wings, assembly fixtures are used to position and clamp components such as spars, ribs, and skins to ensure the accuracy of adhesive bonding or riveting.

[0003] Existing airfoil assembly fixtures are mainly vertical, which are used in small-batch, large-size airfoil assembly due to their advantages such as small footprint and good visibility of airfoil references. However, vertical assembly fixtures are mostly vertical integral welded structures or segmented splicing structures, with a large slenderness ratio, which easily exceeds the allowable limits of structural design. They are also susceptible to lateral bending loads and have insufficient overall overturning stiffness. During drilling, riveting, and other operations, the fixtures are easily affected by operational vibrations, resulting in elastic deformation. Especially for airfoils with high aspect ratios, the positioning error increases progressively with the vertical span, making it difficult to maintain a stable, high-precision assembly reference over a long period. Summary of the Invention

Position the second skin at the second work station and ensure that the lower part of the second skin is suspended in the air; After the adhesive between the first skin and the wing rib structure has initially cured, the adhesive is applied to the outer surface of the contact area between the first skin and the wing rib structure and the second skin. Then, the assembly slide is moved to the second work station, and the first skin is pushed into the inner cavity of the second skin along the direction from the wing root to the wing tip. After the adhesive has fully cured, the second skin is released from its fixation to obtain the wing assembly.

[0006] In conjunction with the first aspect, in one possible implementation, the first skin is a Z-shaped cross-section skin, and the second skin is a C-shaped cross-section skin; The wing tip of the first skin is pushed into the wing root opening of the second skin, and the pushing direction is consistent with the moving direction of the mounting slide.

[0007] In conjunction with the first aspect, in one possible implementation, process lugs are provided on both sides of the second skin; before the second skin is suspended and fixed, the second skin is initially snapped onto the clamping plate fixing seat through the process lugs to achieve initial positioning; then the second skin is adsorbed and fixed, so that the lower part of the second skin is in a suspended state.

[0008] In conjunction with the first aspect, in one possible implementation, the linear movement of the assembly slide is achieved by a guide mechanism disposed between the tooling base and the assembly slide, and the position of the assembly slide is locked at the first station and the second station by a limiting structure on the assembly slide.

[0009] In conjunction with the first aspect, in one possible implementation, the rib structure includes a front rib box, a middle rib box, and a rear rib box, which are temporarily fixed to the corresponding rib positioning plates by detachable fasteners. The front rib box and the rear rib box are respectively fixed to the two outer side walls of the zigzag cross-section skin; The central rib box is fixed inside the zig-shaped cross-section skin; The fastener is at least one of a hand-tightening screw or a quick-release pin.

[0010] Secondly, embodiments of this application provide a push-in wing surface assembly fixture, comprising: Tooling base; An assembly slide is slidably connected to the tooling base and can reciprocate linearly between the first station and the second station. A lifting component, disposed on the assembly slide, is used to position and support the first skin at the first work station; A clamping plate fixing seat is fixedly mounted on the tooling base; A skin positioning assembly is disposed on the clamping plate fixing seat for positioning and holding the second skin in the second working position, and keeping the lower part of the second skin in a suspended state, with the inner cavity of the second skin facing the first skin to accommodate its insertion.

[0011] In conjunction with the second aspect, in one possible implementation, the skin positioning component includes: A card plate assembly is disposed on the card plate fixing base; An adsorption component, disposed on the card plate fixing seat, is used to adsorb and fix the surface of the second skin, keeping it suspended.

[0012] In conjunction with the second aspect, in one possible implementation, a guide mechanism is provided between the tooling base and the assembly slide, the guide mechanism including a first slide rail and a second slide rail that cooperate with each other; the first slide rail is disposed on the top of the tooling base, and the second slide rail is disposed on the bottom of the assembly slide; a limit seat is provided on the tooling base to limit the travel of the assembly slide at the first work station and the second work station.

[0013] In conjunction with the second aspect, in one possible implementation, the assembly slide includes a slide frame and multiple slide supports; the second slide rail is disposed at the bottom of the slide frame; the multiple slide supports are spaced apart along the length direction of the slide frame, and the tops of the multiple slide supports together form a lifting plate reference plane; the multiple lifting components are spaced apart along the length direction of the lifting plate reference plane, and one of the lifting components is provided with a joint positioning structure for positioning the wing joint; and limit structures are respectively provided at both ends of the assembly slide.

[0015] One or more technical solutions provided in the embodiments of this application have at least the following technical effects: This application adopts a horizontal push-in assembly scheme, aligning the gravity direction of the wing surface with the support direction. This effectively avoids elastic deformation caused by lateral bending and vibration, resulting in a short reference transfer chain with no error amplification effect, and maintaining a stable, high-precision assembly reference over a long period. Push-in assembly is achieved through a multi-station layout (the first station completes the bonding of the first skin and wing rib structural components, and the second station completes the positioning of the second skin and suspends it below) and the movement of the assembly slide. The assembly process is clear and convenient, significantly improving assembly efficiency and tooling utilization. The second skin is suspended below, providing a reliable guarantee for the interference-free push-in of the first skin. The tooling of this application can be adapted to different machine models by changing the assembly slide, meeting flexible production needs and easily integrated into automated continuous production lines. This effectively solves the technical problem that existing vertical tooling cannot adapt to the needs of large-volume, low-cost, and high-reliability assembly. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0021] This application provides a method for wing assembly, employing a push-in wing assembly fixture. The push-in wing assembly fixture includes a fixture base 1, an assembly slide 2 movably mounted on the fixture base 1, and a clamping plate fixing seat 3 mounted on the fixture base 1. The method includes the following steps: S1: Place the first skin 6 on the lifting assembly 23 on the assembly slide 2, and when the assembly slide 2 is in the first working position, bond the wing joint 10 and multiple wing rib structural members 5 to the corresponding positions of the first skin 6 and fix them.

[0022] Specifically, the first skin 6 is placed on the support assembly 23 on the assembly slide 2. The support assembly 23 is arranged at intervals along the wingspan direction to form a stable support reference. When the assembly slide 2 is in the first position, the wing joint 10 and multiple wing rib structural components 5 are coated with adhesive and then bonded to the corresponding positions of the first skin 6. They are temporarily fixed by detachable fasteners 101 such as joint positioning pins, hand screws or quick-release pins to ensure the positional accuracy of each component during the bonding and curing process.

[0023] S2: Position the second skin 4 at the second work station and make the lower part of the second skin 4 suspended in the air.

[0024] Specifically, the process lugs 41 provided on both sides of the second skin 4 are used to initially attach it to the card plate fixing seat 3 to achieve initial positioning; then the adsorption component 72 is used to adsorb and fix the surface of the second skin 4, so that its lower part is in a completely suspended state, thereby reserving an interference-free accommodating space for the subsequent pushing in of the first skin 6, while making the inner cavity of the second skin 4 face the direction of the first skin 6.

[0025] S3: After the adhesive between the first skin 6 and the wing rib structure 5 has initially cured, apply adhesive to the outer surface of the contact area between the first skin 6 and the wing rib structure 5 and the second skin 4. Then move the assembly slide 2 to the second station and push the first skin 6 into the inner cavity of the second skin 4 along the direction from the wing root to the wing tip.

[0026] Specifically, after the adhesive between the first skin 6 and the wing rib structure 5 has initially cured, the positioning components (such as joint positioning pins, hand screws, quick-release pins, etc.) used to fix the wing joint 10 and the wing rib structure 5 are removed. Then, adhesive is applied to the outer surface of the contact area between the first skin 6 and the wing rib structure 5 and the second skin 4. Subsequently, the assembly slide 2 is moved linearly through the guide mechanism 8 (the first slide rail 81 and the second slide rail 82 that cooperate with each other) set between the tooling base 1 and the assembly slide 2, moving the assembly slide 2 from the first station to the second station, and locking the position through the limit seat 9. Finally, the first skin 6 is pushed linearly into the inner cavity of the second skin 4 along the direction from the wing root to the wing tip.

[0027] S4: After the adhesive has fully cured, release the fixation on the second skin 4 to obtain the wing assembly.

[0028] Specifically, after the adhesive has fully cured, the fixation to the second skin 4 is released (including removing the clamping plate assembly 71 and shutting off the air supply to the adsorption assembly 72), as follows: Figure 5 As shown, the process lugs 41 on the second skin 4 are polished to obtain a complete wing component product.

[0029] This application adopts a horizontal push-in assembly scheme, aligning the gravity direction of the wing surface with the support direction. This effectively avoids elastic deformation caused by lateral bending and vibration, resulting in a short reference transfer chain with no error amplification effect, and maintaining a stable high-precision assembly reference over a long period. Push-in assembly is achieved through a station-based layout (the first station completes the bonding of the first skin 6 and wing rib structure 5, and the second station completes the positioning of the second skin 4 and suspends it below) and the movement of the assembly slide 2. The assembly process is clear and convenient, significantly improving assembly efficiency and tooling utilization. The second skin 4 is suspended below, providing a reliable guarantee for the interference-free push-in of the first skin 6. The tooling of this application can be adapted to different machine models by changing the assembly slide 2, meeting flexible production needs and easily integrating into automated continuous production lines. This effectively solves the technical problem that existing vertical tooling is difficult to adapt to the needs of large-volume, low-cost, and high-reliability assembly.

[0030] In this embodiment, the first skin 6 has a Z-shaped cross-section, and the second skin 4 has a C-shaped cross-section. The wingtip of the first skin 6 is pushed into the wing root opening of the second skin 4, and the pushing direction is consistent with the moving direction of the mounting slide 2.

[0031] Specifically, the first skin 6 is a Z-shaped cross-section skin with an upward-facing opening. For example... Figure 14 As shown, the contact area in step S3 includes: the outer sides of the top two side areas and the outer sides of the bottom horizontal side area of ​​the first skin 6, the upper and lower surfaces of the front rib box 51 and the rear rib box 53, and the upper surface of the middle rib box 52.

[0032] It should be noted that this application uses a zigzag cross-section skin as the first skin 6 and a C-shaped cross-section skin as the second skin 4, and pushes the wingtip of the first skin 6 into the second skin 4 from the wing root opening along the sliding direction. At the same time, it defines the top and bottom outer areas of the first skin 6, the upper and lower surfaces of the front rib box 51 and the rear rib box 53, and the upper surface of the middle rib box 52 as the adhesive contact areas, ensuring accurate alignment and full fit of the adhesive surfaces during the pushing process, and improving the adhesive strength and structural consistency of the wing assembly.

[0033] In this embodiment, process lugs 41 are provided on both sides of the second skin 4. Before suspending and fixing the second skin 4, the second skin 4 is initially snapped onto the clamping plate fixing seat 3 through the process lugs 41 to achieve preliminary positioning. Then, the second skin 4 is adsorbed and fixed, so that the lower part of the second skin 4 is in a suspended state.

[0034] This application achieves the initial snap-fit ​​positioning of the second skin 4 through the process lug 41, and then combines it with adsorption fixation to make its lower part suspended, which ensures the positional stability and interference-free state of the second skin 4 during the pushing process, and improves the assembly accuracy and reliability.

[0035] In this embodiment, the linear movement of the assembly slide 2 is achieved by the guide mechanism 8 disposed between the tooling base 1 and the assembly slide 2, and the position of the assembly slide 2 is locked at the first work station and the second work station by the limiting structure 24 on the assembly slide 2.

[0036] This application achieves precise linear movement of the assembly slide 2 through the guide mechanism 8, and locks the position at the first and second workstations in combination with the limiting structure 24, ensuring the accuracy of the pushing direction and the repeatability of the position of the first skin 6, and improving the assembly accuracy and the operational reliability of the tooling.

[0037] In this embodiment, the rib structure 5 includes a front rib box 51, a middle rib box 52, and a rear rib box 53, which are temporarily fixed to the corresponding rib positioning plates 102 by detachable fasteners 101. The front rib box 51 and the rear rib box 53 are respectively fixed to the two outer side walls of the Z-shaped cross-section skin. The middle rib box 52 is fixed inside the Z-shaped cross-section skin. The fastener 101 is at least one of a hand-tightening screw or a quick-release pin.

[0038] It should be noted that this application achieves precise positioning and stable maintenance of the wing rib structure 5 during the bonding and curing process by fixing the front rib box 51 and the rear rib box 53 to the two outer side walls of the zigzag cross-section skin, and fixing the middle rib box 52 to the inside of the zigzag cross-section skin, and temporarily fixing them with fasteners 101 such as hand-tightened screws or quick-release pins and corresponding rib positioning plates 102. At the same time, the fasteners 101 are easy to remove quickly after curing, which improves assembly efficiency and ease of operation.

[0039] This application provides a push-in wing surface assembly fixture, such as... Figures 1 to 14 As shown, the push-in wing surface assembly fixture includes a fixture base 1, an assembly slide 2, a lifting assembly 23, a clamping plate fixing seat 3, and a skin positioning assembly 7. The assembly slide 2 is slidably connected to the fixture base 1 and can reciprocate linearly between a first station and a second station. The lifting assembly 23 is disposed on the assembly slide 2 and is used to position and support the first skin 6 in the first station. The clamping plate fixing seat 3 is fixedly disposed on the fixture base 1. The skin positioning assembly 7 is disposed on the clamping plate fixing seat 3 and is used to position and hold the second skin 4 in the second station, so that the lower part of the second skin 4 is suspended in the air, and the inner cavity of the second skin 4 faces the first skin 6 to accommodate its push-in.

The clamping plate component 71 is disposed on the clamping plate fixing base 3 and is used to clamp or engage the process lugs 41 on both sides of the second skin 4. The adsorption component 72 is disposed on the clamping plate fixing base 3 and is used to adsorb and fix the surface of the second skin 4, keeping it suspended.

[0044] Furthermore, the skin bracket 35 is provided with positioning slots for engaging with the process lugs 41 on both sides of the second skin 4.

[0045] In one embodiment of this application, the adsorption assembly 72 includes a suction cup 721, an air tube 722, and an air source. The suction cup 721 includes a silicone base 7211, a screw 7212, and two nuts 7213. The screw 7212 is fixedly connected to a fixing seat via the two nuts 7213.

The skin fixing seat 7214 is connected to the clamping plate assembly 71.

[0046] In this embodiment, a guide mechanism 8 is provided between the tooling base 1 and the assembly slide 2. The guide mechanism 8 includes a first slide rail 81 and a second slide rail 82 that cooperate with each other. The first slide rail 81 is located at the top of the tooling base 1, and the second slide rail 82 is located at the bottom of the assembly slide 2. A limit seat 9 is provided on the tooling base 1 to limit the travel of the assembly slide 2 at the first and second work positions.

[0047] In one embodiment of this application, a base reference plane 13 is provided on the top of the tooling base 1, a first slide rail 81 is provided on the base reference plane 13, and a limit seat 9 is provided at both ends of the first slide rail 81, and a polyurethane buffer pad 91 is provided on the limit seat 9.

[0048] It should be noted that this application achieves precise linear guidance of the assembly slide 2 through the cooperation of the first slide rail 81 and the second slide rail 82, and limits the stroke of the first and second workstations and provides flexible buffering through the limiting seat 9 with polyurethane buffer pad 91, ensuring the smoothness of the movement of the assembly slide 2, the accuracy of the positioning and the reliability of repeated positioning, and avoiding damage to the tooling and wing surface components by rigid impact.
