Removable Abrasive Assembly for Fast Ceramic Tool Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing abrasive assemblies require the supporting body to be removed from the rotating head for tool replacement, leading to downtime and high production costs due to tight machining tolerances and uncomfortable tool insertion.
Innovation Solution
An abrasive assembly with removable fastening means, including fastening elements and clamping means, allows tools to be easily mounted and replaced without detaching the supporting body from the rotating head, using centering means for precise alignment and a fastening ring nut for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the supporting body is removed from the rotating head for tool replacement, then the abrasive tools can be replaced, but production downtime increases and productivity decreases
Solution Approach 1:
The abrasive tool is segmented into a modular design with a separate mounting portion that can be independently replaced. The tool body and mounting portion are distinct components that allow the mounting portion to be swapped without removing the entire supporting body from the rotating head, thus maintaining productivity while enabling easy tool replacement.
Solution Approach 2:
The mounting portion of the abrasive tool is designed to nest within the seat on the supporting body. The coupling walls of the mounting portion fit into corresponding recesses in the seat, creating a nested configuration that secures the tool in place while allowing quick replacement without disassembling the entire assembly.
2Stability of the object's composition
If the seat is designed with double dovetail conformation for secure clamping, then tool holding stability improves, but machining tolerances must be tight and insertion becomes uncomfortable
Solution Approach 1:
The coupling walls of the mounting portion are designed with asymmetric inclination angles that differ from the seat's dovetail angles. This asymmetric design allows the tool to be inserted with minimal friction and discomfort while still achieving secure clamping through the clamping elements, eliminating the need for tight machining tolerances between the tool and seat.
Solution Approach 2:
Clamping elements are introduced as intermediary components between the mounting portion and the seat. These clamping elements engage with both the coupling walls of the mounting portion and the corresponding features in the seat, providing secure tool holding without requiring precise geometric matching between the tool and seat, thus reducing machining tolerance requirements.
3Strength
If the coupling walls have the same inclination as the dovetails, then secure clamping is achieved, but tool insertion becomes difficult and uncomfortable
Solution Approach 1:
The coupling walls of the mounting portion are designed with different inclination angles compared to the seat's dovetail configuration. This asymmetric design reduces friction during insertion, making tool mounting comfortable and easy, while the clamping elements provide the necessary strong clamping force to secure the tool firmly during operation.
Solution Approach 2:
Clamping elements serve as intermediaries that bridge the gap between the mounting portion and the seat. These elements can be adjusted or tightened to provide strong clamping force without requiring the coupling walls to have high-friction angles, thus enabling both easy insertion and secure holding.
