Aircraft Component Processing Layout With Offset Lower Tool Carrier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing processing installations for aircraft structural components require large operating heights and dimensions due to the coaxial orientation of tool axes, limiting the compactness and accessibility of the processing area.
Innovation Solution
The lower tool carrier axis is offset, allowing the tool axes to extend non-coaxially relative to the lower tool carrier axis in certain processing positions, creating free space for the clamping frame and structural components, thereby reducing the operating height and overall installation dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the tool axes are oriented coaxially relative to the lower tool carrier axis, then the processing precision and tool alignment are improved, but the operating height and installation dimensions increase significantly
Solution Approach 1:
The patent transitions from a vertical coaxial arrangement to a horizontal offset arrangement. The lower tool carrier axis is displaced horizontally relative to the tool axes, allowing the clamping frame to be positioned in the horizontal plane rather than requiring vertical space. This dimensional change resolves the contradiction by maintaining tool alignment precision while eliminating the need for large operating height.
Solution Approach 2:
The lower tool carrier is made rotatable about a vertical axis, allowing dynamic repositioning of the tool carrier relative to the clamping frame. This rotational capability enables the system to adapt its configuration, maintaining coaxial tool alignment when needed while allowing horizontal offset positioning to reduce operating height when the clamping frame needs to be accessed from below.
2Stability of the object's composition
If the lower tool carrier is positioned directly under the lower tool, then the structural stability is improved, but the free space for component arrangement is reduced
Solution Approach 1:
The lower tool carrier is extracted from its traditional position directly under the lower tool and relocated to a horizontal offset position. This extraction creates a vertical free space between the lower tool carrier mounting surface and the lower tool, allowing the clamping frame to be positioned in this newly created space. The structural stability is maintained through the offset configuration and rotational support mechanism.
Solution Approach 2:
The clamping frame is nested within the free space created by the offset lower tool carrier configuration. The C-shaped clamping frame can be positioned vertically with its lower portion extending into the free space between the lower tool carrier mounting surface and the lower tool, effectively utilizing the newly created vertical volume for component arrangement.
3Adaptability or versatility
If the clamping frame is rotated through 180° between riveting operations, then the processing versatility is improved, but the required installation dimensions increase
Solution Approach 1:
The patent changes the rotation plane from vertical to horizontal. The lower tool carrier rotates about a vertical axis, allowing the clamping frame to be repositioned horizontally between operations rather than requiring vertical rotation space. This enables 180° rotation for processing different sides of the aircraft component while maintaining a compact vertical profile and reducing overall installation volume.
