Composite Milling Tool Holder Supporting Area
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In micro fine milling operations, the dense arrangement of milling tools on milling drums makes tool replacement challenging due to limited space, leading to operator safety issues and difficulties in accessing and removing tools from the rear of the receiving channel.
Innovation Solution
A composite tool design with a supporting area on the rear milling tool holder that provides stabilized guidance and support for the tool replacement device, allowing it to be knocked out from the front holder, featuring a guide trough that prevents transverse slippage and allows unhindered guidance to the forward holder, increasing available space and reducing the risk of injury.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If milling tools are densely arranged on the milling drum to increase productivity, then the quantity of milling tools increases, but the space for tool replacement becomes limited and operator safety is compromised
Solution Approach 1:
The patent combines the supporting function and guidance function into a single integrated supporting area structure on the milling drum. This supporting area serves dual purposes: providing structural support for the tool replacement device and guiding its positioning through the guide trough, thereby eliminating the need for separate components and freeing up space in the densely arranged tool configuration.
Solution Approach 2:
The supporting area acts as an intermediary element between the milling drum and the tool replacement device. It provides a stable interface that facilitates tool replacement operations while maintaining the dense arrangement of milling tools on the drum, thus mediating between the conflicting requirements of high tool density and adequate replacement space.
2Quantity of substance
If milling tools are arranged with closer line spacing to increase density, then productivity improves, but the available space for safe tool replacement operations decreases
Solution Approach 1:
The supporting area is designed with localized specific features - a flat supporting surface for stability and a guide trough for directional guidance. These local structural qualities provide the necessary safety and operational space exactly where tool replacement occurs, while the rest of the milling drum maintains maximum tool density with closer line spacing.
3Ease of operation
If a supporting area with stabilized guidance is added to the milling tool holder, then operator safety and comfort during tool replacement improve, but the device complexity increases
Solution Approach 1:
The supporting area is designed as a multi-functional component that simultaneously provides structural support, guides the tool replacement device through the guide trough, and stabilizes the operation during tool replacement. By combining multiple functions into a single structure, the overall device complexity is minimized while still achieving the safety and operational benefits.
