Description

Technical Field

[0001] This invention belongs to the field of aerospace assembly technology and relates to an auxiliary device for embedded assembly positioning of integrated systems and its usage method. Background Technology

[0002] Currently, most integrated systems inside aircraft are assembled by embedding into the structure after it has been assembled into a barrel. With the continuous improvement of aircraft assembly efficiency, in order to meet the installation quality requirements of aircraft integrated systems, the traditional method of installation relying solely on manual handling and pushing is not only time-consuming and labor-intensive, affecting product production schedules, but also prone to damaging the integrated system and surrounding structures during handling and installation. Therefore, it is necessary to design a device with hoisting and clamping functions to ensure the installation quality of the integrated system. Summary of the Invention

[0003] This invention provides an auxiliary device and its usage method for embedded assembly positioning of integrated systems, which solves the technical problem of low installation efficiency of aircraft integrated systems and failure to meet assembly quality requirements. It enables the device to move up and down in the vertical direction and rotate 180 degrees in the horizontal direction, solving the problem of inability to quickly and accurately position the integrated system during installation. The device uses a threaded tightening structure to apply a continuous axial feed force to the integrated system, minimizing damage to the connection structure with the integrated system, and is highly practical.

[0004] The present invention adopts the following technical solution:

[0005] An auxiliary device for embedded assembly positioning of an integrated system, the auxiliary device comprising a long screw 1, a nut plate 2, a front pad 3, a rear pad 4, a counterweight 5, a limiting device 6, a suspension 7, and a crane 8.

[0006] The crane 8 includes a base, a horizontal arm, and a vertical arm. The bottom of the base is equipped with rollers for moving the entire auxiliary device. The vertical arm is mounted on the base, and the rear end of the horizontal arm is rotatably connected to the top of the vertical arm, making the height of the horizontal arm adjustable. The front end of the horizontal arm is equipped with a hook.

[0007] The limiting device 6 is a sleeve structure with a limiting pin. Its two ends are installed between the horizontal arm and the vertical arm of the crane 8 through pins. Each of the mating ends of the two sleeves has an elongated hole. After the height of the horizontal arm is adjusted to the correct position, the limiting pin is connected in the elongated hole to fix the height of the horizontal arm.

[0008] The main body of the suspension 7 is a long rod with two lifting points on its lower rear surface, corresponding to the A and B lifting points on the integrated system, for hoisting the integrated system. The front end of the long rod adopts a triangular frame with multiple columns for installing counterweight 5. The installation of counterweight 5 keeps the hoisted integrated system horizontal. The upper surface of the suspension 7 adopts a triangular lifting ring structure and is installed on the hook of the horizontal arm of the crane 8.

[0009] The long screw 1 is a hollow cylindrical rod with a threaded rear end and a smooth middle section. A pad support surface is provided at the front end for limiting the front pad 3. A steering wheel handle is provided at the front end of the long screw 1 for rotating the long screw 1.

[0010] The front pad 3 is a block structure with a central through hole and a disc on one side. The angle between the disc and the axis of the through hole of the front pad 3 is set according to the inclination angle of the end face of the integrated system end. An annular boss is made on the disc for fastening inside the integrated system end. It passes through the front end of the long screw 1, and the side without the disc is attached to the pad support surface of the long screw 1.

[0011] The rear pad 4 is a disc with a central through hole, which is fitted onto the rear end of the long screw 1. The nut plate 2 is located behind the rear pad 4 and is threadedly engaged with the long screw 1. By rotating the nut plate 2 and the handle on the long screw 1 in the opposite direction, the nut plate 2 drives the front pad 3 to move toward the integrated system, and finally installs the integrated system into its final position.

[0012] A method of using the above-mentioned auxiliary device for embedded assembly positioning in an integrated system includes the following steps:

[0013] Step 1: Connect the two suspension points on the hanger 7 to the two suspension points on the integrated system using bolts.

[0014] Step 2: Use the horizontal arm of crane 8 to lift the integrated system to a reasonable installation height, and insert a limiting pin into the elongated hole of the limiting device 6 to fix the height of the horizontal arm; during the lifting process, add counterweights 5 as needed on the column of the suspension 7 to ensure that the integrated system is in a horizontal state.

[0015] Step 3: Attach the front pad 3 to the end of the integrated system, push the crane 8 to move the integrated system to the installation position on the machine body and align it; pass the long screw 1 through the front pad 3, the integrated system, the structure on the machine body that cooperates with the integrated system, the rear pad 4 and the nut plate 2 in sequence, rotate the steering wheel handle of the long screw 1 and the nut plate 2 in the opposite direction to squeeze the integrated system into the final position.

[0029] The crane 8 includes a base, a horizontal arm, and a vertical arm. The bottom of the base is equipped with rollers for moving the entire auxiliary device. The vertical arm is mounted on the base, and the rear end of the horizontal arm is rotatably connected to the top of the vertical arm, making the height of the horizontal arm adjustable. The front end of the horizontal arm is equipped with a hook.

[0030] The limiting device 6 is a sleeve structure with a limiting pin. Its two ends are installed between the horizontal arm and the vertical arm of the crane 8 through pins. Each of the mating ends of the two sleeves has an elongated hole. After the height of the horizontal arm is adjusted to the correct position, the limiting pin is connected in the elongated hole to fix the height of the horizontal arm.

[0031] The main body of the suspension 7 is a long boom with two lifting points on its lower rear surface, corresponding to lifting points A and B on the muffler. These points are used to suspend the muffler. Lifting point A on the muffler is an open hole, while lifting point B is a round hole. After the muffler is installed, the operating space is not open, and the bolt at lifting point A cannot be manually removed. However, after the bolt at lifting point B is manually removed, lifting point A will automatically detach. The front end of the long boom adopts a triangular frame with four columns for installing counterweight 5. The counterweight 5 keeps the suspended muffler horizontal. The upper surface of the suspension 7 is mounted on the hook of the horizontal arm of the crane 8 using a triangular lifting ring structure.

[0032] The long screw 1 is a hollow cylindrical rod with a threaded rear end and a smooth middle section. A pad support surface is provided at the front end for limiting the front pad 3. A steering wheel handle is provided at the front end of the long screw 1 for rotating the long screw 1.

An annular boss is made on the disc for fastening inside the muffler end. It passes through the front end of the long screw 1, and the side without the disc is attached to the pad support surface of the long screw 1.

[0034] The rear pad 4 is a disc with a central through hole, which is fitted onto the rear end of the long screw 1. The nut plate 2 is located behind the rear pad 4 and is threadedly engaged with the long screw 1. By rotating the nut plate 2 and the handle on the long screw 1 in the opposite direction, the nut plate 2 drives the front pad 3 to move toward the muffler, and finally installs the muffler into its final position.

[0035] The method of using the above-mentioned auxiliary device for embedded assembly positioning in integrated systems includes the following steps:

[0036] Step 1: Connect the two suspension points on the hanger 7 to the two suspension points on the muffler using bolts.

[0037] Step 2: Use the horizontal arm of crane 8 to lift the muffler to a reasonable installation height, and insert the limiting pin into the elongated hole of the limiting device 6 to fix the height of the horizontal arm; during the lifting process, add counterweight 5 as needed on the column of the suspension 7 to ensure that the muffler is in a horizontal state.

[0038] Step 3: Attach the front pad 3 to the end of the muffler, push the crane 8 to move the muffler to the installation position on the body frame plate and align it; pass the long screw 1 through the front pad 3, muffler, body frame plate, rear pad 4 and nut plate 2 in sequence, rotate the steering wheel handle of the long screw 1 and the nut plate 2 in the opposite direction to squeeze the muffler into the final position.
