Floating Deburring Tool Holder With Adjustable Compression and Tension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deburring tool holders for CNC machines lack axial flexibility and are limited to either compression or tension, making it difficult to accurately deburr complex workpieces like castings or parts with cross holes, as they do not allow for simultaneous adjustment of biasing forces in both directions.
Innovation Solution
A deburring tool holder that incorporates both compression and tension springs, allowing for axial flexibility and adjustable biasing forces in both directions, enabling precise deburring on both top and underside surfaces without the need to disassemble the tool holder or change springs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a deburring tool holder uses only compression or tension springs, then it can provide biasing force in one direction, but it cannot accommodate complex workpieces requiring both compression and tension forces
Solution Approach 1:
The patent combines both compression and tension springs within a single tool holder assembly, allowing the tool to apply biasing forces in both compression and tension directions simultaneously. This merging of opposing force mechanisms enables the tool to accommodate complex workpiece geometries requiring multi-directional deburring capabilities
2Ease of operation
If extra springs of different biasing force values are supplied, then the pressure applied to the part can be adjusted, but the tool must be disassembled to change springs
Solution Approach 1:
The patent incorporates an adjustable mechanism that allows the biasing force to be dynamically modified without disassembling the tool holder. The adjustment mechanism enables operators to change compression and tension spring pre-loads in real-time, transforming a static spring system into a dynamically adjustable one that adapts to different workpiece requirements on-the-fly
3Manufacturing precision
If the deburring tool holder is rigid, then it provides stable force application, but it cannot compensate for variations in workpiece edge definition
Solution Approach 1:
The patent employs spring-based biasing mechanisms that introduce controlled flexibility into the rigid tool holder structure. The springs allow the tool to adapt its position and force application parameters when encountering undefined or varying edge geometries, while the adjustable pre-load capabilities maintain consistent deburring pressure across different workpiece variations

AI summary
Disclosed is a deburring tool holder that may be used in combination with a computer controlled machine with a rotating spindle allowing for the provision of biasing forces on the deburring tool in both compression and tension, including a preset or predetermined amount of biasing force independent for compression versus tension.
