Abstract

The invention belongs to the technical field of aerospace and particularly relates to a skin structure and a connecting method. The skin structure comprises skin boards, buckles and locating pieces. The locating pieces are fixedly arranged on the skin boards and can be matched with fixing devices on to-be-connected pieces, so that the skin boards are fixed to the relative positions of the to-be-connected pieces. Each buckle is fixedly arranged at one end of the corresponding skin board, the buckles are provided with openings capable of being connected with the end faces of the to-be-connectedpieces in a matched mode, and the openings in the buckles are matched with the end faces of the to-be-connected pieces so that the skin boards can be fixedly connected to the to-be-connected pieces. By the adoption of the skin structure and skin installation and detachment methods, the skin installation and detachment processes can be quickly finished, the connected structure is more stable and reliable, seamless connection can be achieved, and the installation size is guaranteed.

Description

technical field

[0001] The invention belongs to the technical field of aerospace, and in particular relates to a skin structure and a method for installing and disassembling the skin. Background technique

[0002] Skins are widely used in the aerospace field. In view of the characteristics of the skin itself, the skin installation mainly adopts mechanical connections such as riveting and bolt connection, or is installed with adhesives. It is mainly used in various aircraft and other aircraft. Applications.

[0003] The traditional skin connection method mainly has the following disadvantages:

[0004] 1. Riveting increases the weight of the overall structure, reduces the strength of the skin, easily causes damage to the skin, and reduces the fatigue strength of the skin.

[0005] 2. Although the bolt connection is suitable for places with high strength requirements, the operation is complicated and requires tools such as wrenches, and for some products, too many types and ...
