Angled Blade Fastening Nut for Debris Suction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machining systems face inefficiencies in dust and residue removal, leading to reduced tool life, increased heat generation, and operational hazards, with existing solutions requiring significant adaptation and additional equipment, and lacking safety mechanisms to prevent tool damage during aggressive machining.
Innovation Solution
A fastening nut with radially angled blades that creates suction when rotated, used in conjunction with a collet chuck system to remove debris and act as a safety barrier by protruding past the nut's end, allowing for integration with existing tools and machines without additional equipment, thereby enhancing dust removal and preventing tool damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If air suction tube is attached to machine operating head to vacuum dust and debris, then dust and debris are removed, but the system is operationally inefficient and does not completely remove generated debris
Solution Approach 1:
The patent creates a comprehensive vacuum system that serves multiple functions: it captures dust and debris at the machining site, transports them through vacuum conduits, and collects them in a reservoir. The system is designed to handle various types of machining operations and different sizes of debris particles, providing universal effectiveness across different machining scenarios rather than being limited to specific conditions.
Solution Approach 2:
The patent replaces inefficient mechanical debris removal methods with a vacuum-based system. Instead of relying on mechanical means that may not completely remove debris, the system uses vacuum pressure differentials to efficiently draw dust and debris through conduits and into a collection reservoir, ensuring more complete and operationally efficient removal of generated debris.
2Object-affected harmful factors
If specifically manufactured tools with keyed or integrated impeller are used to remove fine and powdery wastes, then fine and powdery wastes are removed with suction, but the tools cannot accept various existing tool bits and working pieces and require significant financial investment
Solution Approach 1:
The patent designs a universal vacuum system with a standardized interface that can accommodate various existing tool bits and working pieces. The vacuum source, conduits, and collection reservoir form a multi-functional system that can handle different types of machining operations and debris types without requiring specifically manufactured tools with integrated impellers. The system maintains adaptability while providing effective fine and powdery waste removal.

Function Achieved in This Case
The solution effectively removes dust and debris during machining, extends tool life by reducing friction and heat, and provides a safety mechanism to prevent tool damage, while being cost-effective and adaptable to existing systems.
Implementation Method 1
Axial rotation of the fastening nut creates a suction proximate the second end of the fastening nut
Data Source
AI summary
A fastening nut for fastening a receiving body and a collet together is disclosed. The fastening nut comprises a main body having an outer surface, a first end, and a second end distal to the first end and a plurality of blades located radially on the outer surface of the main body, wherein each blade is at an angle to the second end. The fastening nut is attachable on the receiving body for coaxial retention of the collet. Furthermore, axial rotation of the fastening nut creates a suction proximate the second end of the fastening nut. In one embodiment of the fastening nut, the plurality of blades protrude axially past the second end of the main body in a direction away from the first end. A tool bit holding system and a system and method for machining specimens comprising the fastening nut are also disclosed.
