Solution Overview
Problem
Current horizontal five-axis machining centers face challenges in efficiently and precisely machining large cutting removal rates for aerospace structural parts, particularly aluminum alloy components, due to difficulties in workpiece loading and unloading and reduced production efficiency.
Innovation Solution
A horizontal five-axis turning plate type machining center is designed with a support base, bed, and column connected by a connecting arm, featuring a turning plate device with driving units for position conversion, double lead screws and slideways for rigidity, and an A/B angle milling head for improved machining accuracy and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the workpiece is directly loaded at the machining station, then the structure is simple, but the loading and unloading efficiency is low and production efficiency is reduced
Solution Approach 1:
The machining center is divided into separate functional modules: a turning plate device for workpiece loading/unloading, an X-direction sliding plate for positioning, and a machining area. This segmentation allows independent optimization of each module, improving loading efficiency without compromising overall structural integrity.
Solution Approach 2:
The turning plate device acts as an intermediary mechanism between the external loading area and the machining station. It mediates the workpiece transfer process, enabling efficient loading/unloading while maintaining a clear separation between the machining area and the workpiece handling area.
2Strength
If double lead screws and slideways are adopted, then the rigidity is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple lead screws and slideways into an integrated positioning system. The first and second Y-direction lead screws work together with corresponding slideways to provide enhanced rigidity and stability for the column and milling head assembly, while maintaining a unified structural design.
Solution Approach 2:
The positioning system extends in multiple dimensions with X-direction sliding plate, Y-direction lead screws, and Z-direction ram. This multi-dimensional arrangement distributes mechanical loads across different axes, improving overall rigidity while organizing complexity spatially.
3Manufacturing precision
If an A/B angle milling head is used, then the machining precision is improved, but the device complexity increases
Solution Approach 1:
The A/B angle milling head incorporates dynamic angle adjustment capabilities, allowing the milling head to be tilted around two axes (A-axis and B-axis). This dynamic positioning enables precise machining of complex angular surfaces while keeping the base milling head structure relatively simple and modular.
