Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional deburring tools experience instability and vibration during machining, leading to uneven work surfaces and reduced cutting tool life due to the combination of mechanical spring and air pressure forces, which limits the ability to handle various burrs effectively.
Innovation Solution
A deburring tool design featuring a cylindrical housing with a tiltable spindle, a piston, an elastic member, a separate ring, and a fluid flow path to supply compressible fluid, allowing for controlled pressure adjustments and reduced vibration through the use of compressible fluid pressure and a tapered ring for stable tool alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a mechanical spring with high reaction rate is used to press the tool holder, then the pressing force response is fast, but vibration is amplified during intermittent machining
Solution Approach 1:
The patent replaces the mechanical spring with a pneumatic pressing mechanism that uses compressed air to apply force to the tool holder. This pneumatic system provides the necessary pressing force without the high-frequency vibration amplification characteristics of mechanical springs, thereby reducing harmful vibrations during intermittent machining while maintaining responsive force application.
Solution Approach 2:
The invention substitutes the mechanical spring-based pressing system with a pneumatic system. This replacement eliminates the mechanical resonance and vibration amplification issues inherent in spring mechanisms, particularly during intermittent deburring operations, while still providing the required axial pressing force through pneumatic pressure.
2Force
If combined force of spring and air pressure is applied to press the tool holder, then the pressing force is sufficient, but the degree of change in machining pressure is low making it difficult to handle various burrs
Solution Approach 1:
The patent implements a dynamic pressing force system where the pneumatic pressure can be independently adjusted and varied during operation. This allows the pressing force to be dynamically adapted to match different burr sizes, shapes, and locations, providing the versatility needed to handle various deburring scenarios without being constrained by a fixed mechanical spring force.
Solution Approach 2:
The invention enables independent adjustment of pneumatic pressure parameters to optimize the pressing force for different deburring requirements. By controlling the air pressure separately from the tool rotation, the system can adapt the pressing force magnitude to suit different burr conditions, enhancing versatility while maintaining sufficient pressing force.
