Description
Technical Field
[0001] This utility model belongs to the field of aircraft maintenance technology, and in particular relates to a cockpit clamping and fixing fixture for repairing damaged aircraft. Background Technology
[0002] During the repair of a certain type of aircraft, the aircraft must be kept in a horizontal parking position. During the disassembly and replacement of aircraft cockpit components, the installation positions of each replacement component must be clamped and fixed, and their positions must not shift due to external forces. Through analysis of the repair technical plan and tooling development task book for the damaged aircraft, the required tooling for this aircraft generally includes three types: adjustment tooling, support tooling, and clamping and fixing tooling.
[0003] The main functions of each type of tooling are as follows:
[0004] 1. Adjusting the tooling: When leveling the aircraft, the altitude is adjusted using a tooling with lifting and lowering functions, thereby bringing the aircraft to a level position.
[0005] 2. Support fixtures: Used to maintain the aircraft's position after it has been leveled, and also to support the main body of the aircraft.
[0006] 3. Clamping and fixing fixture: clamp and fix the replacement component in the determined installation position to prevent its position from changing during installation.
[0007] To ensure the smooth progress of the repair of a certain type of aircraft, a set of clamping and fixing fixtures for the structural damage repair of the aircraft is urgently needed during the adjustment and clamping work. After the aircraft is leveled, the clamping and fixing work of the aircraft's cockpit door frame beam, rear wall panel, central floor and upper half of the four frames is carried out by adjusting the hoisting position.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in detail below.
[0021] This utility model provides a cockpit clamping and fixing fixture for repairing damaged aircraft, belonging to the category of damaged aircraft repair fixtures. The bottom of the damaged aircraft repair fixture is a ground platform, and the cockpit clamping and fixing fixture is mounted on this ground platform. Figure 1 This fixture is used to clamp and secure the aircraft cockpit door frame beam, rear bulkhead, central floor, and upper half of the frame after the aircraft has been leveled. The cockpit clamping and securing fixture is a three-axis movable gantry structure, including a gantry frame 1, an X-axis adjusting beam 3, a Y-axis adjusting beam 2, a lifting mechanism 4, and protective slings 5. After assembly, it is as follows: Figure 2 and Figure 3 As shown; the overall internal dimensions of the gantry frame 1 are (3800×3000×4600)mm, and it is made of square steel pipes of Q235A (160×160×12)mm. The gantry columns and beams are connected by bolts. The entire frame is a detachable structure for easy transportation. A 20mm thick Q235A plate is installed at the bottom of each gantry column as a base plate for fixing it to the ground platform. Four 12mm thick Q235A reinforcing ribs are welded between each base plate and the gantry column. Figure 4As shown, multiple φ5mm process holes of different heights are machined at the top of the gantry columns (the holes are enlarged according to the actual bolt size during installation). After the gantry frame 1 is erected, diagonal bracing can be added according to the stability requirements. One end of the diagonal bracing is screwed to the gantry column, and the other end is fastened to the ground platform. There are two Y-axis adjustment beams 2, which are installed in parallel between the gantry columns. They are made of Q235A / (200×150×8)mm rectangular steel pipes, and the flange structure made of Q235A / δ12mm steel plates at both ends is fixedly connected to the gantry columns through process holes. By connecting with process holes of different heights, the height along the Z-axis can be adjusted according to the actual position requirements. Multiple φ5mm mounting holes are pre-drilled in the horizontal direction on the Y-axis adjustment beams 2 according to the actual working position. There are two X-axis adjustment beams 3, which are installed in parallel between the two Y-axis adjustment beams 2. The beam is constructed using rectangular steel pipes of Q235A (150×75×10)mm. Flange structures made of Q235A / δ12mm steel plates are welded to both ends of the beam and connected to the Y-axis adjusting beam 2 via mounting holes. By connecting different mounting holes, the installation position along the Y-axis adjusting beam 2 can be adjusted, forming an adjustment mechanism for the XY-axis plane. The X-axis adjusting beam 3 and the Y-axis adjusting beam 2 together constitute the XYZ three-dimensional motorized structure. The X-axis adjusting beam 3 has multiple φ5mm process holes pre-drilled horizontally according to actual working needs, for the installation of the hoisting mechanism 4. Multiple hoisting mechanisms 4 are provided, all made of Q235A steel. Their tops are fixedly installed on the process holes of the X-axis adjusting beam 3. By connecting the process holes at different positions, the installation position along the X-axis adjusting beam 3 can be adjusted. The bottom has C-shaped clamps used to clamp and fix components in the cockpit that need to be repositioned in the installation position, such as... Figure 5 As shown; the protective sling 5 is a synthetic fiber circular sling made of high-strength polyester filament. It has the characteristics of being soft, lightweight, having a large lifting force, a high safety factor, being non-conductive, and having strong wear resistance. It will not cause scratches on the surface of the aircraft. The two ends of the protective sling 5 are connected to the crossbeam of the gantry frame 1 for fixing the nose of the aircraft.
[0022] During installation, while the gantry frame 1 is being mounted, all beams and columns of the gantry frame 1 are continuously laser-calibrated using the coordinate system after the aircraft has been leveled, ensuring their horizontality and verticality. The protective slings 5 are connected at both ends to the beams of the gantry frame 1, and their length is adjusted to secure the nose. After the position of the hoisting mechanism 4 is determined, threaded holes are drilled at the corresponding positions on the X-axis, and bolts are used for connection. C-clamps are used to clamp and fix the components in the cockpit that require repositioning to the installation position, such as... Figure 6 As shown.
