Problems solved by technology

At present, there are researches involving composite material auxiliary fuel tanks at home and abroad, but the existing composite material auxiliary fuel tanks use a honeycomb sandwich structure, which has redundant structures and heavy weight. However, this application proposes a thin-walled composite material auxiliary fuel tank for the first time. structure
[0004]At present, the assembly process of the auxiliary fuel tank mostly adopts the integral frame and pallet assembly process, the assembly device is complicated, the manufacturing cost is high, and the flexibility is poor, which is not conducive to large-scale promotion
In addition, when assembling the sub-tank body of the segmented auxiliary fuel tank with the existing overall frame and pallet sheet technology, the splicing process is not stable enough to easily lead to poor coating quality of the adhesive, and structural defects appear after the auxiliary fuel tank is bonded, thus The sealing performance and molding quality of the thin-walled auxiliary fuel tank are reduced

Embodiment 1

[0038] The technical problem to be solved in this embodiment is that at present, the assembly process of the auxiliary fuel tank mostly adopts the overall frame and the clamping board assembly process. The end face is coated with adhesive on the spliced ​​end face. Whether the thickness of the adhesive between the spliced ​​end faces is uniform is related to whether the overall structure of the auxiliary fuel tank is stable. When assembling the segmented auxiliary fuel tank body with the existing overall frame and pallet sheet technology, the splicing process is not stable enough, which will easily lead to poor adhesive coating quality, and structural defects will appear after the auxiliary fuel tank is hot-pressed, reducing the The quality of the thin-walled auxiliary fuel tank is improved.

Abstract

The invention provides a thin-wall auxiliary fuel tank assembling device and method, and relates to the technical field of aviation aircraft lightweight. A linear sliding rail is arranged on an assembling platform; a limiting buffer device is arranged in the middle of the assembling platform and comprises a clamping piece, a driving mechanism and a triggering mechanism; the trigger mechanism is arranged between a first tool frame and a second tool frame; and when the first tool frame and the second tool frame move oppositely to a threshold distance, the driving mechanism controls a limiting plate to fall into the sliding way of the linear sliding rail and limits the first tool frame and the second tool frame to continue to move oppositely. According to the thin-wall auxiliary fuel tank assembling device and method, the smooth butt joint between a front-section auxiliary fuel tank body and a rear-section auxiliary fuel tank body within a threshold value range is achieved, the smooth coating and bonding quality of adhesives are guaranteed; the assembly of a thin-wall auxiliary fuel tank is simple, convenient and easy to operate, the control is accurate, and particularly the axial bonding precision is high; and the problems that a traditional assembling process is complex in tool, inaccurate in control and high in assembling cost are solved.

Description

technical field [0001] The invention relates to the technical field of lightweight aircraft, in particular to an assembly device and an assembly method for a thin-walled auxiliary fuel tank. Background technique [0002] The auxiliary fuel tank is an important part of the aircraft. During the flight of the aircraft, it not only provides fuel supply, but also bears a large aerodynamic load. Therefore, it has high requirements on the aerodynamic shape and structural strength. On the basis of ensuring fuel supply and structural strength, the lightweight thin-walled composite auxiliary fuel tank can reduce the structural weight of the auxiliary fuel tank and increase the take-off weight and service radius of the aircraft. [0003] Since the existing auxiliary fuel tank is made of metal material, its structural weight is relatively large, so this application proposes to use composite materials to manufacture the thin-walled auxiliary fuel tank to reduce its structural weight. At...
