[0030] 3) Integrated transportation functions can improve transfer efficiency, shorten assembly cycle, and save costs.

[0031] The technical solution of this application will be further illustrated by a specific embodiment below:

[0032] The technical problem to be solved by this invention is,

[0033] This invention provides an aircraft cockpit riveting bracket that integrates transportation, multi-component adaptation, and dual-attitude riveting functions, thereby addressing the aforementioned pain points, improving assembly efficiency, quality, and safety, and reducing tooling costs.

[0034] The complete technical solution provided by this invention is as follows:

[0035] This integrated bracket mainly consists of two parts: a flip-up assembly and a bottom bracket. The flip-up assembly can use a minimal number of common locators to position and secure two product components: the "sunroof frame assembly" and the "nose cockpit assembly," enabling multi-component compatibility. The bottom bracket supports the weight of the flip-up assembly and the product components, and features swivel casters for component transport. Together with the flip-up assembly, it allows for both horizontal and vertical riveting of the product to achieve better ergonomics.

[0036] Brief introduction to the functions of each major component, such as Figure 1 Indication:

[0037] 1) Positioner: The threaded pin is inserted into the product positioning hole to complete the product positioning and tightening;

[0038] 2) Clamping device: It can rotate and clamps the product and tooling together during use to ensure that the product is stable and does not shake during riveting.

[0039] 3) Limiting support: When the product is in a "horizontal" position, its pin cooperates with the fork lug of the flipping component to fix the product's position;

[0040] 4) Handles: Used for pushing and pulling this integrated bracket;

[0041] 5) Limiting seat: When the product is in an "upright" position, its pin and fork lug cooperate to fix the product's posture;

[0042] 6) Rotary pivot support: It serves as a pivot for attitude conversion when the flipping assembly flips;

[0043] 7) Shape-maintaining support assembly: retractable, used for skin support and shape maintenance of the "nose cockpit assembly";

[0044] 8) Fork lugs: When the product is in an "upright" position, they work with the limit seat to fix the product's posture.

[0045] 9) Gas spring: Used to assist in posture changes. When changing from "horizontal" to "vertical", it limits the rotation speed to prevent impact caused by excessive speed when falling due to gravity; when changing from "vertical" to "horizontal", it assists the worker in pushing.

[0046] 10) Handle-type support legs: After the tooling is moved into place, rotate the handle to support it on the ground to fix the tooling;

[0047] 11) Swivel casters: When the handle-type outriggers are retracted, tooling and products can be moved using them.

[0048] Instructions for use: First, insert and secure the pin in the limit support to ensure the fixture is in a "horizontal" position. Then, raise the handle-type support, move the fixture near the product assembly fixture, and lock the handle-type support legs. Next, transfer the product from the assembly fixture to this bracket and secure it using the positioner, clamp, and support components to complete the riveting work in the accessible area in the "horizontal" position. Then, pull out the pin in the limit support and manually push the fixture and product to change their positions. Align the fork lugs with the pin holes of the limit support and connect and secure them with the pins to complete the remaining riveting work in the "vertical" position. Then, depending on the product's subsequent workstation position, change it to "horizontal" as needed and move the product to the subsequent workstation. Finally, retract the handle-type support legs, move the fixture to the planned area, and lock the handle-type support legs.

[0049] Specifically,

[0050] Multi-component compatibility allows for the completion of riveting work after the "sunroof frame assembly" or "cockpit assembly" is fixed by different locators or clamping and support structures.

[0051] Dual-position riveting: Based on ergonomic considerations, this bracket is designed to be flip-up, allowing free switching between "horizontal" and "vertical" postures for easy riveting operations at specific locations. With speed limiting and assistance provided by a gas spring, the flipping process is labor-saving, stable, and safe.

[0052] The integrated transportation function features a bracket with handle-type support legs and swivel casters for fixing and moving the tooling, combining riveting and transportation functions into one.
