Dual-Tool Carriage for Short Workpiece Machining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machining devices are inefficient for processing workpieces shorter than 1.2 meters, as the distance between tools limits simultaneous machining capabilities, resulting in reduced efficiency for shorter workpieces.
Innovation Solution
A processing device with a displaceable workpiece holder and guide means, where two tools are arranged side by side on a carriage, allowing for reduced tool distance and simultaneous machining of shorter workpieces, with adjustable tools for varying workpiece widths and depths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If two tools are arranged on separate tool carriages on both sides of the portal, then machining capacity is increased for long workpieces, but the distance between tools becomes too large (at least 1.2m) to be effective for shorter workpieces
Solution Approach 1:
The patent combines two tools onto a single tool carriage that moves on one side of the portal. This merging allows both tools to be positioned close together (distance can be less than 1.2m) while maintaining the capability for simultaneous machining operations, thereby resolving the contradiction between machining capacity and tool distance for shorter workpieces
Solution Approach 2:
The tool carriage is designed to move not only in the horizontal direction along the portal but also in the vertical direction and transverse direction. This multi-dimensional movement capability allows two tools to be arranged in a compact configuration while still accessing different areas of the workpiece, enabling simultaneous machining with reduced tool distance
2Adaptability or versatility
If the workpiece holder and guide means are made displaceable, then flexibility for different workpiece sizes is improved, but device complexity increases
Solution Approach 1:
The displaceable workpiece holder and guide means are designed to serve multiple functions: they enable processing of workpieces of different lengths, widths, and heights, and accommodate various tool configurations. This multi-functionality justifies the added complexity by providing universal adaptability across different machining scenarios
Solution Approach 2:
The system transitions from static to dynamic components, where the workpiece holder and guide means can be displaced to different positions. This dynamic capability allows the machine to adapt to different workpiece dimensions and machining requirements, improving versatility despite increased structural complexity
