Abstract

The invention provides an arch-shaped clamp for bonding and loading an off-line reloading heat-insulating tile of an aircraft, which comprises a detachable joint, a tail end joint, a lifting ring, a felt, a pressing block and a pressing block felt. The arch-shaped clamp transmits the loading force to the heat insulation tile and the bonding interface through the heat insulation tile profiling tool. The space path planning is realized by the change and rotation of the number of joints of the arched card passing through the beam arm, so that the requirement of bonding and loading the whole-area heat insulation tiles of the aircraft and the high-Mach-number aircraft by the arched card is met, the heat insulation tiles in other areas cannot be damaged in the process of replacing and installing the heat insulation tiles, and the tooling cost is lower than that of a scheme using a sliding rail and a mechanical arm and is short in period.

Description

Arch-shaped clamp for bonding and loading heat insulation tile for offline replacement and installation of aircraft

Technical Field

The invention belongs to the technical field of part assembly, and particularly relates to an arch-shaped clamp for bonding and loading an off-line replacement heat insulation tile of an aircraft.

Background

The high-mach-number aircraft and the aerospace vehicle are both reusable aircraft for more than 20 times, when the aircraft flies in the atmosphere, the outer surface of the aircraft is rubbed with air to generate a large amount of aerodynamic heat, a reusable protection system needs to be laid to protect a projectile body and an inner projectile component, and a heat insulation tile is a typical structure. The complex force thermal coupling environment of high temperature and high enthalpy medium scouring and vibration, etc. faced by aircraft in flight requires that the heat-insulating tile adopts the low-stress and high-damage tolerance assembling process method, and the gluing is the most suitable technical approach at present.

Due to physical impact, thermal insulation tile fatigue, adhesive thermal failure and the like, the aircraft needs to detect the appearance quality and the bonding quality of the thermal insulation tile again in an off-line state, and when the quality of the thermal insulation tile cannot meet the requirements and cannot be repaired, the thermal insulation tile needs to be replaced quickly. The characteristics of high Mach number airplanes and aerospace vehicles determine that vacuum loading cannot be adopted for heat insulation tile replacement, and the loading of the bow-shaped clamp in mechanical loading is most convenient and effective.

Detailed Description

In order to make the objects, contents and advantages of the present invention clearer, the following detailed description of the embodiments of the present invention will be made in conjunction with the accompanying drawings and examples.

The embodiment provides an arch-shaped card for bonding loading of an off-line reloading heat insulation tile of an aircraft, which comprises a detachable joint 4, a tail end joint 5, a lifting ring 3, felt 6, a pressing block 10 and a pressing block felt 9, as shown in figures 1 and 2.

The number and the size of the detachable joints 4 are determined according to the size of the cabin section 8, the number of the detachable joints 4 is four, and the detachable joints 4 and the tail-end detachable joint 4 and the tail-end joint 5 are connected with the connecting nut 2 through the connecting bolt 1; a lifting ring 3 for lifting the whole arch-shaped card is arranged on one detachable joint 4 positioned at the gravity center position of the arch-shaped card; the contact part of the tail end joint 5 and the heat insulation tile 7 on the surface of the cabin section 8 is of a conformal design, and can be replaced according to the molded surface of each cabin section 8; a felt 6 for protecting the heat insulation tile 7 is arranged on the surface, which is attached to the heat insulation tile 7, of the tail end joint 5; the pressing block 10 is installed at the end of the jacking nail 11, is connected with the first section detachable joint 4 through the jacking nail 11, can compress the heat insulation tile 7 on the surface of the cabin section 8 through the jacking nail 11, and the surface of the pressing block 10, which is attached to the heat insulation tile 7, is provided with a pressing block felt 9.

The two beam arms of the bow card of the embodiment are designed into a plurality of detachable joints 4, so that the application points of the bonding loading of the aircraft heat insulation tile can be fully covered in the length and angle directions.

The arch-shaped card of the embodiment is made of metal materials with certain strength, so that the transmission of loading force on the beam arm can be met; a plurality of joints are arranged on the beam arm and are adjustable in the horizontal direction; the arch-shaped clamp is connected with the heat insulation tile profiling tool in a reliable force transmission mode.

The use method of the bow card in the embodiment specifically comprises the following steps:

1) measuring the distance from the thermal insulation tile to be replaced to the edge of the aircraft, and calculating the number of joints required by the bow card;

2) hoisting by using a gantry crane, and hoisting the arch-shaped clamp to a thermal insulation tile loading position;

3) performing rotary fine adjustment on joints of the arched clamp in the horizontal direction, and planning the spatial position distribution of a beam arm of the arched clamp;

4) and loading the arch-shaped card by using a rotating mechanism and a heat insulation tile profiling tool.
