Description

Technical Field

[0001] This utility model belongs to the field of aircraft assembly technology, and in particular, it is a flexible and adjustable support device suitable for the installation of ribs or beams of various box-shaped components. Background Technology

[0002] During the flight of large aircraft, wing ribs play a crucial role in transferring loads, and their planar accuracy after installation is directly related to the aerodynamic performance of the wing. Furthermore, due to the large size of large aircraft wings, wing ribs are generally large, thin-walled structures with poor rigidity. Maintaining the conformal shape of wing ribs has always been a key focus and challenge in the assembly of large wing boxes. Because of the large size, numerous number, and close spacing of wing ribs, it is difficult to simultaneously achieve lightweight and stable conformal frame design. A lightweight design reduces the stiffness of the conformal frame, causing it to deform with the wing ribs during use; a stable design increases the size of the conformal frame, making construction extremely difficult and posing safety hazards due to limited space. Typically, rib conformal shaping of aircraft wing boxes involves adding tooling conformal struts between the ribs to fix them together and ensure their relative positional relationship. The disadvantages of this method are: the conformal struts between each rib need to be designed individually based on the distance between the ribs, and there are many conformal struts between adjacent ribs. The conformal struts are also quite heavy, making manual installation difficult. Furthermore, the installation position is fixed, and the position of the conformal struts cannot be adjusted after installation, affecting the assembly and construction process. At the same time, its applicability is poor, and it cannot meet the universality requirements of multiple models, resulting in increased assembly and manufacturing costs. Utility Model Content

The product includes ribs 9 and stringers 10. The base 1 is located directly above the stringer 10 of the product. The flexible adjustable strut 2 is connected to the middle of the base 1, and its length is adjusted by the adjusting bolt 3. A tightening joint 4 is installed at the top of the flexible adjustable strut 2 to support the position of the product ribs 9. One end of the base 1 has an adjustable support 5, and clamping bolts 6 are installed at both ends of the adjustable support 5 to clamp the bottom end of the product ribs 9. An adjustable bolt 7 is located in the middle of the adjustable support 5 to adjust the position of the adjustable stringer clamping block 8, ensuring that the adjustable stringer clamping block 8 can adapt to the product stringer 10.

[0031] In use, the base of the flexible adjustable support device is first placed on the upper surface of the product's stringer. The length of the flexible strut is adjusted using adjusting bolts, ensuring that the top clamping joint connects and is fixed to the hole on the rib component, providing support for the rib's top. The bottom of the rib is then tightened using the clamping bolts at both ends of the adjustable support, ensuring support at the bottom of the rib. Finally, the height of the adjustable stringer clamping block is adjusted using adjusting bolts to ensure it clamps the stringer, fixing the support to the product's stringer and rib positions, thus completing the device's shape-maintaining support function for the product.

[0032] like Figure 6 As shown, the base 1 includes a base sliding groove 1-1, a stringer locking groove 1-2, and an adjustable support connecting groove 1-3. The base sliding groove 1-1 is used for sliding the bottom end of the flexible adjustable support rod 2 within the groove during adjustment.

This clamps the stringer according to its shape. Another adjustable stringer clamping block is installed at the other end of the base. The adjustable support device is then secured to the product using these two adjustable stringer clamping blocks.

[0036] 1) When using, first place the base of the adjustable support device directly above the two adjacent stringers of the wall panel, ensuring that the two ends of the lower surface of the base are in contact with the upper surface of the stringers;

[0037] 2) Simultaneously rotate the bolts on the adjustable stringer clamping blocks in the middle of the adjustable supports at both ends of the base. Adjust the bolts to adjust the adjustable stringer clamping blocks, ensuring that the adjustable stringer clamping blocks contact the end faces of the two adjacent stringers and clamp the stringers.

[0038] 3) Rotate the two clamping bolts at both ends of the adjustable support to bring the clamping bolts into contact with the bottom of the box-shaped component rib and clamp the bottom of the rib;

[0039] 4) Rotate the adjusting bolt in the middle of the flexible adjustable strut to adjust the length of the flexible adjustable strut, so that the tightening joint at the top of the flexible adjustable strut passes through the hole at the top of the rib and fixes the rib to the flexible adjustable strut;

[0040] 5) Observe whether the position of the ribs meets the theoretical requirements, and at the same time check whether all the bolts on the flexible adjustable support device are tightened, so as to finally complete the support and shape retention requirements of the box-type component rib parts.

[0041] This method solves the problem of difficult conformal bracket installation when installing box-shaped components such as wing box ribs or beams. It also meets the universal conformal support requirements for box-shaped components with different configurations, reduces the labor intensity of workers installing conformal brackets, avoids the positioning risks associated with conventional conformal struts, and increases the stability and convenience of flexible adjustable support device installation, thereby improving the assembly quality of box-shaped components. The device is easy to use and operate, and can quickly and accurately support and conform to the rib positions, improving production efficiency on the assembly site and making it widely applicable.
