Curved Panel Clamping Support for Accurate Thickness Machining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Chemical milling for panel thickness processing in aircraft components is labor-intensive, time-consuming, and costly, and existing machine-based methods struggle with processing accuracy due to variations in frame shape and non-uniform sectional shapes.
Innovation Solution
A processing device with a restricting portion that abuts against one surface of a panel-shaped first portion and presses the other surface, while a movable supporting portion supports a panel-shaped second portion, allowing for stable processing regardless of the angle between the portions, and includes sensors and control units to ensure accurate abutment and reduce deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a uniform reference surface is used to support the frame, then the supporting device structure is simple, but processing accuracy reduces due to deformation when the frame shape varies
Solution Approach 1:
The supporting surface is made movable in the panel thickness direction of the second portion, allowing it to dynamically adjust its position according to the actual shape of each frame component. This dynamic adjustment capability enables the supporting surface to adapt to variations in bending angles and sectional shapes, preventing deformation while maintaining processing accuracy without requiring a complex fixed structure
Solution Approach 2:
The position of the supporting surface along the panel thickness direction is changed as a variable parameter rather than being fixed. By allowing the supporting surface to move to different positions, the system can accommodate different frame shapes and sizes, ensuring accurate support and processing for each specific component geometry
2Adaptability or versatility
If chemical milling is used for panel thickness processing, then processing can be performed on complex shapes, but processing time increases and costs increase
Solution Approach 1:
The patent replaces the chemical milling process with a mechanical processing system that uses a pressing portion to apply force and a processing unit to perform panel thickness reduction. This mechanical approach eliminates the need for chemical solutions and extended processing times while maintaining the ability to handle complex frame shapes through proper mechanical support and positioning
Solution Approach 2:
The processing system is designed to automatically adapt to the workpiece geometry through the movable supporting surface and pressing mechanism, eliminating the need for manual intervention and complex setup procedures that would increase processing time

AI summary
The aim of the present invention is to provide a processing device and a processing method, with which it is possible to improve processing accuracy. A processing device processes a work piece which integrally includes a plate-shaped first curved-surface section and a plate-shaped planar-surface section that extends from the edge of the first curved-surface section in a bending manner.
