Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine tool systems for machining wood, wood-based materials, or plastics face limitations in chip management, as they often require specific tool systems and chip deflectors that are not adaptable to different manufacturers' systems, leading to inefficiencies in chip guidance and tool exchange processes.
Innovation Solution
A tool quick-change system with a separable tool interface and a torque arm connected to a chip guide device, allowing for independent operation and easy tool exchange, featuring a frictional and positive connection via a hollow shaft, and a chip guiding device that can be rotated to optimize chip deflection without affecting the workpiece.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If chip deflectors are permanently installed on tool mandrels for specific tool systems, then chip guidance is optimized for that tool system, but adaptability to different tool systems is reduced and assembly variance increases
Solution Approach 1:
The system is divided into separate components: the tool mandrel and the chip deflector are independent elements that can be assembled and disassembled. The tool mandrel remains permanently mounted on the machine tool, while the chip deflector can be attached to or removed from the tool mandrel depending on the tool system being used. This segmentation allows different chip deflectors to be used with different tool systems without requiring permanent installation of multiple specialized assemblies.
Solution Approach 2:
The tool mandrel is designed with a universal interface that can accommodate different tool systems and corresponding chip deflectors. The mounting structure on the tool mandrel allows various chip deflector designs to be attached, making a single tool mandrel assembly capable of working with multiple different tool systems and chip management requirements.
2Productivity
If tools are permanently mounted on tool mandrels with integrated chip deflectors, then chip extraction is optimized, but tool exchange time increases and cleaning becomes difficult
Solution Approach 1:
The chip deflector is designed as a separate component that can be removed from the tool mandrel. This allows the tool mandrel to be quickly exchanged without removing the chip deflector, enabling fast tool changes. Meanwhile, the chip deflector itself can be completely detached for thorough cleaning in areas that would be inaccessible if the deflector were permanently integrated.
Solution Approach 2:
The chip deflector is extracted from the permanent integration with the tool mandrel, allowing it to be independently removed. This extraction enables the tool mandrel to be quickly swapped while the chip deflector remains on the machine, and allows the chip deflector to be completely removed for cleaning when needed.
3Object-generated harmful factors
If extraction hoods completely enclose the tool, then chip extraction is optimized, but lateral machining capability is lost and chip direction control is reduced
Solution Approach 1:
The chip deflector is designed with adjustable and rotatable elements that can dynamically adapt to different machining operations. The deflector can be positioned to guide chips in different directions depending on whether the operation is end milling, lateral machining, or other operations, providing both effective chip extraction and adaptability to different machining capabilities.
Solution Approach 2:
The chip deflector structure incorporates different local features for different functions: some areas provide enclosed chip collection for vertical chip ejection, while other areas provide open configurations for lateral chip evacuation. This allows the same deflector structure to handle different chip flow patterns required by different machining operations.
