Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional clamping devices for laser welding require multiple clampers to maintain welding intervals, leading to increased manufacturing costs and potential interference issues when welding points are closely located, restricting the size of welding jigs and affecting welding quality.
Innovation Solution
A clamping device with rotatable upper and lower links and rollers that use an operating cylinder to adjust the distance between rollers, allowing for stable fixation and maintenance of welding intervals without the need for multiple clampers, thereby simplifying the jig structure and reducing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple clampers are used to maintain welding intervals, then welding interval maintenance is improved, but manufacturing cost increases and device complexity increases
Solution Approach 1:
The clamping device is divided into an upper clamping link with upper rollers and a lower clamping link with lower rollers, which can rotate independently around a hinge shaft. This segmentation allows each link to function separately yet cooperatively, maintaining welding intervals without requiring multiple complete clamping assemblies.
Solution Approach 2:
The upper and lower clamping links are designed to rotate dynamically around the hinge shaft, allowing the distance between upper and lower rollers to be adjusted. This dynamic mechanism enables a single clamping device to adapt to different welding interval requirements, replacing the need for multiple fixed clampers.
2Manufacturing precision
If multiple clampers are disposed on jigs, then welding interval maintenance is improved, but jig size restriction increases and interference occurs
Solution Approach 1:
The clamping device with rotatable links and rollers serves multiple functions: it clamps the welding object, maintains welding intervals, and adapts to different welding point arrangements. This multi-functional design eliminates the need for multiple specialized clampers, improving versatility for closely located welding points.
Solution Approach 2:
The dynamic rotation capability of the clamping links allows the device to adjust to various welding configurations, including closely located welding points that would be inaccessible to fixed multiple clampers, thereby improving adaptability.
3Manufacturing precision
If multiple clampers are used, then welding interval maintenance is improved, but manufacturing cost increases
Solution Approach 1:
The upper clamping link and lower clamping link are merged into a single integrated clamping device that rotates around a common hinge shaft. This merging reduces the total number of components needed compared to using multiple separate clampers, thereby reducing manufacturing cost while maintaining welding interval precision.
Solution Approach 2:
The single clamping device with rotatable links performs the work of multiple clampers, reducing the number of parts that need to be manufactured and assembled, which directly lowers manufacturing cost.
