Background Art

[0002] During the aircraft manufacturing process, the various components of each section of the aircraft often cannot be assembled using only one set of assembly tooling due to limited operating space and tooling obstructions. The aircraft cockpit is an important part of the nose structure. 30% of the work in the cockpit and skylight frames requires riveting, and under-frame riveting brackets are required to support the under-frame assembly of the components. However, traditional brackets can only meet single-use requirements. Separate brackets are required for cockpit components and skylight frame components, as well as for different component placement postures. That is, one set of riveting brackets is set for each component and each posture. Some components that require displacement require rollers to be installed on the brackets for displacement, which will greatly increase the floor space and tooling manufacturing costs.

[0024] The complete technical solution provided by the present invention is: This integrated bracket primarily consists of a flip assembly and a bottom bracket. The flip assembly uses a minimum of common positioners to position and secure the two product components, the "skylight frame component" and the "nose cockpit component," achieving multi-component adaptation. The bottom bracket supports the weight of the flip assembly and the product components, and features universal casters for component transport. Combined with the flip assembly, it enables dual-position riveting in both horizontal and vertical positions to achieve optimal ergonomics.

[0025] Brief introduction of the functions of main components, such as Figure 1 Hint: 1) Positioner: The threaded pin is inserted into the product positioning hole to complete the product positioning and tightening; 2) Compressor: It can rotate and press the product and tooling together to ensure that the product is stable and does not shake during riveting; 3) Limit support: When the product is in the "horizontal" position, its latch cooperates with the fork ear of the flip assembly to fix the product position; 4) Handle: used to push and pull the integrated bracket; 5) Limit seat: When the product is in the "vertical" position, its pin cooperates with the fork ear to fix the product position; 6) Rotating shaft support: It serves as the rotating shaft for posture conversion when the flip assembly flips; 7) Shape-conserving support group: retractable, used for skin support and shape preservation of the "nose cockpit assembly"; 8) Fork ear: When the product is in the "vertical" position, it cooperates with the limit seat to fix the product position; 9) Gas spring: used to assist in posture conversion. When converting from "horizontal" to "vertical", it limits the rotation speed to prevent collision caused by excessive speed when falling due to gravity; when converting from "vertical" to "horizontal", it helps workers push; 10) Handle-type support foot: After the tooling is moved into place, rotate the handle to support it on the ground to fix the tooling; 11) Universal casters: After the handle-type support legs are folded, the tooling and products can be moved by them.

[0026] Instructions for use: First, insert and fix the pin in the limit support to ensure that the tooling is in a "horizontal" posture, then raise the handle support, move the tooling to the vicinity of the product assembly tooling and lock the handle support legs, then transfer the product from the assembly tooling to this bracket and fix the product through the positioner, clamper and support assembly to complete the riveting work in the area accessible in the "horizontal" posture; then pull out the pin in the limit support and manually push the tooling and product to change postures, align the fork ear with the pin hole of the limit seat and connect and fix it with the pin, and complete the remaining riveting work in a "vertical" position; then, depending on the posture of the subsequent workstation of the product, convert it to "horizontal" as needed and move the product to the subsequent workstation; finally, retract the handle support legs, move the tooling to the planned area and lock the handle support legs.

[0027] Specifically, Multi-component adaptation, after fixing the "skylight frame component" or "cockpit component" through different positioners or pressing and supporting structures, the riveting work can be completed; Dual-position riveting: Based on ergonomic considerations, the bracket is designed to be reversible and can be freely switched between "horizontal" and "vertical" positions, which is convenient for riveting operations at specific positions. The gas spring limits the speed and assists the reversing process, making it labor-saving, stable and safe. Integrated transportation function: the bracket is equipped with handle-type support feet and universal casters for fixing and moving tooling, integrating riveting and transportation functions into one.
