Aircraft Panel Assembly with Movable Jig for Automatic Riveting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing aircraft panel production methods require multiple positioning jigs for different shapes, increasing manufacturing and management costs, and limit the application of automatic riveting due to interference with support members and restricted movement of panels between processes.
Innovation Solution
An aircraft panel production method where plate-like members are fastened together by rivets and held by a movable holding jig, allowing for automatic riveting across multiple processes without the need for frequent jig changes, and a buffer space for time difference absorption, reducing labor and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple positioning jigs are manufactured for different body panel shapes, then positioning accuracy for various panel shapes is improved, but manufacturing cost and management complexity of jigs increase
Solution Approach 1:
The positioning jig is designed with a movable support member that can change its position along the body panel, allowing a single jig to accommodate multiple body panel shapes. The support member can be repositioned to different locations based on the required panel shape, making the positioning jig universal rather than shape-specific.
Solution Approach 2:
The support member of the positioning jig is made movable rather than fixed, enabling it to adapt to different body panel shapes by changing its position. This dynamic capability allows the same positioning jig to handle various panel configurations without requiring multiple dedicated jigs for each shape.
2Manufacturing precision
If the body panel is fixed to the positioning jig at a predetermined position, then positioning accuracy is improved, but the range of automatic riveting machine application is limited due to interference with support members
Solution Approach 1:
The support member is designed to be movable along the body panel rather than fixed, which eliminates interference with the automatic riveting machine. The support member can be repositioned to clear the riveting path while maintaining positioning accuracy, enabling broader application of automatic riveting.
Solution Approach 2:
The movable support member acts as an intermediary between the positioning requirement and the riveting operation. It can be positioned to provide accurate panel support when needed and moved out of the way when the automatic riveting machine needs access, resolving the conflict between positioning accuracy and riveting accessibility.
3Adaptability or versatility
If the body panel is moved between work places by removing and remounting it on positioning jigs, then flexibility in production layout is improved, but labor time and work complexity increase
Solution Approach 1:
The positioning jig with its movable support member can handle multiple body panel shapes and processes, allowing the same jig to be used across different work places. This universality eliminates the need to transfer panels between different specialized jigs, reducing transfer time and simplifying production layout flexibility.
Solution Approach 2:
The positioning and support functions are merged into a single movable support member within the positioning jig. This integration allows the panel to remain securely positioned during movement between work places without requiring separate positioning and support mechanisms, reducing complexity and transfer time.
4Manufacturing precision
If a large number of positioning materials are disposed corresponding to frame intervals, then positioning accuracy for frame attachment is improved, but the range of automatic riveting machine application is further limited
Solution Approach 1:
Instead of using multiple fixed positioning materials at frame intervals, the invention uses a single movable support member that can be repositioned to provide positioning as needed. This dynamic approach reduces the number of positioning materials from many fixed elements to one movable element, clearing the path for automatic riveting while maintaining accuracy.
Solution Approach 2:
The invention extracts the essential positioning function from multiple distributed positioning materials and concentrates it into a single movable support member. This extraction eliminates unnecessary positioning materials that would interfere with automatic riveting while preserving the core positioning capability through the movable support member.

AI summary
The objective of the present invention is to provide an aircraft panel production method and aircraft panel production system with which an aircraft panel can be assembled accurately. This aircraft panel production method has: a step in which a holding jig (1) holds a body panel (10), which has a plurality of plate-like members having a curved cross-sectional shape, such that the cross section of the body panel (10) has an upwardly bulging curved shape; a step in which the plate-like members of the body panel (10) held by the holding jig (1) are overlapped with each other and the overlapping portions are joined by a rivet; a step in which the holding jig (1), which is holding the body panel (10) of which the plate-like members have been joined to each other, is moved; and a step in which a frame (32) that follows the curved shape of the body panel (10) is joined, by a rivet, to the plate-like members of the body panel (10) which is held by the holding jig (1) which has been moved.
