Swiveling Machining Head for Single-Clamp Frame Corner Machining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machining devices for frames welded from profile pieces, such as window or door frames, require significant design effort and programming complexity to move and rotate tools on a robot arm or to arrange multiple movable tool carriers, resulting in inefficiencies and high costs.
Innovation Solution
A machining device with a swiveling machining head and a positioning shaft that can be rotated, allowing for the machining of frame corners and profile legs in a single clamping position using a variety of tools, including drills and milling cutters, with enhanced flexibility and precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If tools are arranged on a robot arm to enable movement and rotation, then the machining of frame corners and profile legs is achieved, but the design effort and programming complexity increase significantly
Solution Approach 1:
The device segments the machining functions into a stationary frame holding multiple machining tools and a separate positioning system with swiveling head and rotatable shaft. This segmentation eliminates the need for complex robot arm programming while maintaining the ability to machine both frame corners and profile legs through coordinated movement of the swiveling head and rotatable positioning shaft
2Adaptability or versatility
If multiple movable tool carriers are arranged to machine frame corners and profile legs, then complete machining is achieved, but the device complexity and programming requirements increase
Solution Approach 1:
The device merges multiple machining tools into a single stationary carrier that holds various tools (milling cutters, drills, countersinks) for machining both frame corners and profile legs. Combined with a swiveling head and rotatable positioning shaft, this merging approach provides complete machining capability while reducing device complexity compared to multiple separate movable tool carriers
3Adaptability or versatility
If tools are positioned on a robot arm with full spatial movement, then all frame surfaces can be accessed, but the programming software effort increases
Solution Approach 1:
The device employs a dynamic positioning system with a swiveling head that can rotate around a vertical axis and a rotatable positioning shaft that can rotate around a horizontal axis. This dynamic configuration allows tools to access all frame surfaces including corners and profile legs through mechanical movement rather than complex software programming, reducing programming effort while maintaining full tool accessibility
