Dual-Standard Tool Holder Coupling to Reduce Spindle Misalignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of interface adapters to connect tool holders or workpiece holders with different standards to machine tool spindles results in reduced workspace and increased misalignment risks, affecting reproducible error accuracy.
Innovation Solution
A tool holder or workpiece holder with a coupling section that can interact with tool interfaces of both SK50 and HSK80 standards, utilizing an adapter ring or dual sections to securely couple with various standards without the need for adapters, ensuring accurate and versatile tooling compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If interface adapters are used to connect tool holders with different standards to machine tool spindles, then compatibility with different standards is improved, but workspace is reduced and misalignment risks increase
Solution Approach 1:
The coupling section is designed with a universal geometry that can directly interface with multiple different standard types (e.g., both HSK and SK standards) without requiring separate adapters. This multi-functional design allows the same coupling section to accommodate various tool holder standards, eliminating the need for interface adapters and thereby preserving workspace.
2Adaptability or versatility
If interface adapters are used to connect tool holders with different standards to machine tool spindles, then compatibility with different standards is improved, but misalignment risks increase affecting reproducible error accuracy
Solution Approach 1:
The coupling section incorporates a universal interface geometry that directly compatibly connects to multiple different standard types (e.g., both HSK and SK standards) without requiring separate adapters. This eliminates additional interface points that could cause misalignment, thereby maintaining reproducible error accuracy while achieving compatibility with different standards.
3Adaptability or versatility
If interface adapters are used to extend the spindle for different standards, then compatibility is improved, but device complexity increases
Solution Approach 1:
The coupling section is designed as a single integrated component with universal geometry that can directly interface with multiple different standard types. This eliminates the need for separate interface adapter components, thereby reducing device complexity while maintaining compatibility with different standards.
