Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamping systems for milling complex extruded profiles are inadequate, leading to vibration, irregular hole patterns, and difficulty in securely clamping irregularly shaped profiles, which results in poor machining quality and increased risk of imperfections.
Innovation Solution
A clamping assembly comprising two or more form blocks on a support plate, which are easily interchangeable and compressible to securely clamp complex profiles from below, preventing vibration and ensuring stable machining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional flat clamps are used to secure profiles on the milling machine, then the clamping mechanism is simple, but complex and irregular profiles cannot be sufficiently clamped, leading to vibration and poor machining quality
Solution Approach 1:
The clamping mechanism is divided into multiple modular form blocks (first form block, second form block, third form block) that can be independently configured on support plates. Each form block can be customized to match specific profile geometries, allowing complex profiles to be securely clamped without requiring a completely new clamping system for each profile type.
Solution Approach 2:
The form blocks are designed to be movable relative to each other and to the support plates, allowing the clamping configuration to be dynamically adjusted for different profile shapes and sizes. This dynamic adaptability enables the same clamping mechanism to handle both simple and complex profiles effectively.
2Force
If profiles are clamped from above, then the clamping force can be applied directly, but the profiles will bend through and vibrations increase during machining
Solution Approach 1:
Instead of clamping the profile from above, the invention inverts the approach by clamping from below using form blocks positioned on support plates. This inverted clamping configuration prevents the profile from bending through during machining while still providing sufficient clamping force to secure irregular profiles and eliminate vibrations.
3Adaptability or versatility
If fixed clamping configurations are used, then the device is simple to manufacture, but it cannot adapt to different profile shapes and sizes
Solution Approach 1:
The clamping assembly is designed with universal support plates that can accommodate multiple form blocks in different configurations. The same support plate structure can be used for various profile types by simply rearranging or replacing form blocks, providing multi-functionality without requiring completely different clamping assemblies for each profile type.
Solution Approach 2:
The system allows for parameter changes in the clamping configuration by adjusting the position, orientation, and combination of form blocks on the support plates. This enables adaptation to different profile geometries while maintaining a consistent basic clamping structure that is relatively simple to manufacture.
