Description

Technical Field

[0001] This invention relates to a tool for installing and fixing the insulation layer inside an aircraft cabin, belonging to the field of non-metallic adhesive bonding technology, and particularly to the field of non-metallic and metal cabin adhesive bonding technology. Background Technology

[0002] An airplane is a precision piece of equipment that flies at high speeds in the air. During high-speed flight, the friction between the aircraft and the air generates a large amount of heat. According to relevant tests and data, when an aircraft reaches Mach 2, the surface temperature will reach 100°C; when the aircraft reaches Mach 3, the surface temperature will reach 350°C; when the aircraft reaches Mach 4, the surface temperature will reach 500°C; the American X-15 reached a speed limit of Mach 6.7, at which time the surface temperature of the aircraft was 732°C.

[0003] The high temperatures generated by high speeds are transmitted through the metal surfaces and frames of the aircraft to the equipment compartment and cockpit, which can cause serious damage to the electronic equipment in the equipment compartment and the occupants in the cockpit. This necessitates the installation of an insulation layer inside the aircraft.

[0004] The insulation layer typically uses non-metallic materials with excellent thermal insulation properties, such as glass wool, basalt wool, polyimide foam, and ceramic wool. To avoid the heat transfer effect of metal rivets and screws, adhesive bonding is used to attach them to the inner surface of the fuselage. During the bonding process between the insulation layer parts and the fuselage, air bubbles in the adhesive need to be compacted and pressure applied until the adhesive cures. Since aircraft fuselages are generally circular, it is difficult to apply pressure for extended periods during the bonding process for the insulation layers on the side and top walls, leading to incomplete curing and subsequent detachment of the insulation layers after bonding. Summary of the Invention

[0005] To overcome the above-mentioned technical problems, the present invention provides a novel fixed combination top fixture for aircraft cabins. Utilizing the principle of axial fixation and top rod support, it achieves the effect of fixing all insulation layers inside the cabin with a single top fixture. It does not require precise positioning, has no interface with the aircraft, offers high installation freedom, and has no limit on the number of units that can be installed.

[0006] The technical solution of the present invention is as follows:

[0007] An installation and fixing tool for an aircraft cabin insulation layer includes a main support structure, a secondary support structure, and a connecting ring; the main support structure is used for bearing the main force of pressing the adhesive; the secondary support structure is used for applying pressure to the adhesive; and the connecting ring is used for connecting the main support rod and the secondary support.

[0008] The main support structure includes a rotary locking lock, a rotary locking head, a thick main support rod, and a thin main support rod, such as... Figure 1As shown, the rotary locking lock and rotary locking head are designed with a threaded structure. Through the threaded connection, the rotary locking lock expands under force, fixing the thin main support rod inside the thick main support rod, achieving the purpose of adjustable length and fixation. The thick main support pad and thick main support rod are also designed with a threaded structure. The threads of the thick main support pad are fully screwed into the thick main support rod. After the length of the main support rod is adjusted and fixed, the thick main support pad is unscrewed to increase the pressure at both ends, thereby fixing the main support rod. The principle of the thin main support pad and thin main support rod is the same as that of the thick main support pad and thick main support rod.

[0009] The auxiliary support structure includes a thin auxiliary support rod and a thick auxiliary support rod; the thin and thick auxiliary support rods are fixed in the same way as the thick main support rod and the thin main support rod; the top block adapter and the thin auxiliary support rod are designed with a threaded structure to increase the pressure of the top block in contact with the adhesive; the top block and the top block adapter are designed with a spherical assembly, allowing the top block to rotate 360° for adjusting the angle and ensuring good contact with the adhesive; the thick auxiliary support rod is designed with two through-hole lugs, which connect to the connecting ring and are connected using quick-release pins to achieve angle adjustment.

[0010] The connecting ring serves as a transition between the main support structure and the secondary support structure. It is secured to the main support rod using fixing bolts that pass through the through holes in the connecting ring. The connecting ring has multiple through holes for connection to the secondary support rod, allowing for the fixing of adhesive components at different angles in the same location. Simultaneously, multiple connecting rings can be fixed to the main support rod, enabling the simultaneous fixing of multiple adhesive components within the cabin.

[0011] A method for using a tool for installing and securing thermal insulation layers inside an aircraft cabin, comprising the following steps:

[0012] Step 1: Shorten the thick main support rod and the thin main support rod to their approximate length inside the cabin.

[0013] Step 2: Remove the thick main support pad and insert the corresponding number of connecting rings according to the position and quantity of the adhesive parts.

[0014] Step 3: Install the coarse main support pad to the lowest point of the thread, rotate the coarse and fine main support rods in the opposite direction to loosen the threads, and stretch the coarse and fine main support rods until their ends inside the compartment contact the coarse and fine main support pads. Rotate the coarse and fine main support rods to achieve a fixed state, and adjust the threads of the coarse main support pad to increase pressure and fix the main support.

[0015] Step 4: Adjust the position of the connecting ring according to the location of the adhesive component, and note the approximate position of the holes on the connecting ring that connect to the secondary support assembly. Secure the connecting ring with the fixing bolts.

[0016] Step 5: Shorten the thin and thick auxiliary support rods to their approximate lengths.

[0017] Step 6: Connect the secondary support assembly to the connecting ring using quick-release pins.

[0018] Step 7: Install the top block adapter to the lowest point of the thread, rotate the fine and coarse auxiliary support rods in the opposite direction to loosen the threads, and stretch the fine and coarse auxiliary support rods until the top block contacts the adhesive. Rotate the fine and coarse auxiliary support rods to a fixed state, and adjust the threads of the top block adapter to increase the pressure so that the top block applies appropriate pressure to the adhesive.

[0019] The beneficial effects of this invention are:

[0020] This invention utilizes a telescopic fixing principle. Inside the cabin, the main support rod is tightened and secured using a rotating locking mechanism. An adapter ring connects the secondary support rod to the main support rod. The secondary support rod connects to a pressure block via a spherical junction. The telescopic fixing principle of the secondary support rod presses the adhesive-coated insulation layer firmly into the cabin, achieving an auxiliary fixing effect. This invention achieves the effect of fixing all insulation layers inside the cabin with a single top mount, requiring no precise positioning, having no interface with the aircraft, offering high installation flexibility, and having no limit on the number of units that can be installed.
