Upper Center Beam Jig With Movable Hood Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional jigs for aligning vehicle components result in large gaps and steps between the hood and bumper face due to alignment errors with the vehicle body, particularly when attaching an upper center beam.
Innovation Solution
A jig system comprising a main body and movable parts that can adjust the position of the upper center beam relative to the vehicle body, using magnets and adjustable abutting surfaces to align with the hood, ensuring precise attachment and minimizing gaps and steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cross member is aligned to the left and right components of the vehicle body using a conventional temporary jig, then the assembly process is simplified, but the gap and step between the hood and bumper face become relatively large due to alignment errors
Solution Approach 1:
The jig incorporates movable parts that can adjust their position dynamically during the assembly process. The first moving part can move in a first direction to accommodate variations in component dimensions, while the second moving part can move in a second direction to maintain alignment with the hood. This dynamic adjustment capability allows the jig to adapt to different assembly conditions while maintaining precise positioning, thereby reducing the gap and step between the hood and bumper face without complicating the assembly process.
2Device complexity
If a fixed jig structure is used for aligning the upper center beam, then the device complexity is reduced, but the alignment precision with the hood cannot be achieved
Solution Approach 1:
The jig is divided into multiple independent parts: a jig main body and at least one moving part. Each part can function independently or in coordination with others. The moving part includes a moving part substrate that can be positioned relative to the jig main body, allowing for adjustable alignment. This segmentation enables the jig to achieve precise alignment with the hood while keeping each individual component relatively simple in structure, thus balancing device complexity with measurement precision.
