Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern machining devices face a conflict between achieving a compact construction with optimal tool accessibility and maximizing rigidity, often resulting in complex and costly locking mechanisms and tool change systems that compromise precision and increase manufacturing costs.
Innovation Solution
A processing head with a clamping device that includes a base body, a processing unit, a bearing device for movable attachment, and a clamping mechanism with defined positioning, allowing for simplified and cost-effective enhancement of axis rigidity by absorbing forces and relieving drive loads, along with a separate release device to reduce complexity and weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If locking means are provided in the processing unit to enable automatic tool change, then tool change capability is improved, but the structure becomes complex and mass increases
Solution Approach 1:
The release device is extracted from the processing unit and provided separately on the base body. The actuating device is provided on the base body to actuate the release device, which in turn actuates the clamping unit. This separation removes the complex tool change mechanism from the processing unit, reducing its mass and structural complexity while maintaining automatic tool change capability.
2Ease of operation
If the processing unit is made compact with optimal tool accessibility, then tool accessibility is improved, but rigidity of the processing head decreases
Solution Approach 1:
The processing head is segmented into a base body and a separate processing unit that can be movably attached. The bearing device provides movable attachment while the clamping device provides fixable attachment. This segmentation allows the processing unit to be positioned for optimal tool accessibility while the base body maintains structural rigidity.
Solution Approach 2:
The connection between the base body and processing unit is made dynamic through the bearing device and clamping device combination. The processing unit can move relative to the base body during operation for optimal accessibility, and can be fixed when rigidity is required. This dynamic connection resolves the contradiction between accessibility and rigidity.
3Strength
If locking means are provided to stiffen the axis, then rigidity is improved, but the structure becomes complex and costly
Solution Approach 1:
The clamping device combines the bearing function and locking function into a single integrated mechanism. The first clamping element and second clamping element work together with the actuating device to provide both support and rigidity. This merging eliminates the need for separate complex locking mechanisms, reducing structural complexity and cost while maintaining axis rigidity.
