Problems solved by technology
The floating self-locking nuts currently used on aircraft are based on the structural design of the United States in the 1960s. Now this structural design is outdated and can be eliminated, and it cannot be reversed. The structural integration design is too poor. Because of its poor safety and reliability, the flight safety factor of aerospace vehicles is low and the maintenance cost is high.

Embodiment Construction
[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings. But it is not used as any limitation basis for the present invention.
[0021] A floating self-locking nut connection assembly that can be double-sidedly glued to the pallet. The connection assembly includes: a pallet 1, a self-locking nut 2, a rubber rod 3, and a bracket 4; There are two types of pallets: non-sealed and non-sealed pallets; the sealed pallet has a top, and the non-sealed pallet has no top; both pallets have a positive bottom surface 6 and a reverse bottom surface 7; they are symmetrical in the middle of the column shell 8 There are 2 or 4 concave and convex bottom grooves. The self-locking nut 2 is made up of a cylindrical cylinder 9, an internal thread 10, and a lug 11; the lug 11 is located in the middle of the outer surface of the cylindrical cylinder 9, and the internal thread 10 is located on the inner surface of the cylindrical cylinder ...

The invention relates to a double-faced cementing supporting plate moving self-lock nut connection assembly and a connection method of the double-faced cementing supporting plate moving self-lock nut connection assembly. The connection assembly comprises a supporting plate, a self-locking nut, a rubber rod and a support. The supporting plate is of cylindrical structure as a whole and is divided into a sealing type and a non-sealing type. The self-lock nut is composed of a cylindrical column body, internal threads and a supporting lug. The supporting lug is located in the middle of the excircle surface of the cylindrical column body. The internal threads are located on the inner surface of the cylindrical column body. The rubber rod is of a cylindrical structure and composed of a rod body and rod joints. The support is of an arch structure and is composed of a supporting leg, a supporting face and a support hole. The double-faced cementing supporting plate moving self-lock nut connection assembly has the advantages of being suitable for being used and mounted in narrow space, simple in structure, convenient to use and mount, capable of being widely applied to connection of military aircraft bodies or civil aircraft bodies, capable of improving mounting working efficiency greatly and lowering labor intensity and meanwhile capable of reducing the machining cost.
Description
technical field [0001] The invention belongs to the field of mechanical manufacturing, and relates to a fastening connector, in particular to a floating self-locking nut connecting assembly for a double-sided adhesive pallet for aviation and a connecting method thereof. Background technique [0002] In the design of aerospace parts, ultra-thin materials and composite materials are used more and more. While the performance requirements of materials are greatly increased, it is also necessary to have higher requirements for the technological content and structural design of the corresponding fastening connectors. On various types of aircraft in the early stage, the floating self-locking nuts on the plastic pallets installed on composite materials and aluminum-magnesium alloy sheets were single-sided glued, and the processing difficulty of the pallets was high. Stretching step pallets in the direction requires high precision of the mold, and the product qualification rate is lo...
