Innovation Solution
A numerical control tool machine design featuring a rotatable table with multiple machining stations and a support system with quick-clamping mechanisms, allowing for fast support changes and precise centering, enabling efficient machining of various pieces without re-clamping, and facilitating chip disposal and tool access through pass-through openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the machine is specialized for high production-volume pieces, then production speed is improved, but versatility is worsened
Solution Approach 1:
The patent implements a universal support system that can accommodate different workpieces through quick-change fixtures and adjustable clamping mechanisms. The support structure includes standardized interfaces and modular components that allow the same machine to process various piece types efficiently, thereby achieving multi-functionality without sacrificing production speed
2Productivity
If the machine is specialized for high production-volume pieces, then production speed is improved, but setup time is worsened
Solution Approach 1:
The patent employs pre-configured support structures and quick-change fixtures that are prepared in advance for different workpiece types. The support system includes pre-positioned clamping elements and adjustable components that can be rapidly reconfigured between productions, eliminating the need for time-consuming manual setup and tooling changes
Solution Approach 2:
The support system is divided into modular, interchangeable components including separate clamping mechanisms, positioning elements, and fixture assemblies. This segmentation allows individual components to be quickly swapped or adjusted without affecting the entire support structure, significantly reducing setup time while maintaining production efficiency
3Productivity
If dedicated machines are designed for high production-volume pieces, then machining speed is improved, but machine cost is worsened
Solution Approach 1:
The patent designs a universal support system with standardized interfaces and modular components that can accommodate multiple workpiece types on a single machine. This eliminates the need for multiple dedicated machines for different piece types, reducing overall equipment investment while maintaining high machining speeds through optimized tool paths and efficient fixture changes
