Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine tools for producing profiles, such as gearing systems, have complex and costly constructions due to the need for additional motion axes for dressing tools, which complicates setup and increases costs, especially when integrating multiple workpiece receiving devices and machining tool profiling devices.
Innovation Solution
A machine tool design featuring a machine bed with a tangential carriage and machine base linear dual guide allows for the integration of multiple workpiece receiving devices and machining tool profiling devices without additional elaborate mechanics, using existing motion axes for dressing and enabling flexible positioning of the machining tool for both machining and profiling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional motion axes are provided for the dressing tool and machining tool, then the machining and dressing functions can be performed, but the device complexity and construction costs increase significantly
Solution Approach 1:
The existing motion axes of the workpiece machining device are made multi-functional by programming the control unit to coordinate their movement for both machining operations and dressing operations. The radial carriage, lifting carriage, and rotational carriage are controlled to position the machining tool for machining, then repositioned to position the dressing tool for dressing, eliminating the need for dedicated motion axes for each function.
2Adaptability or versatility
If the machining tool profiling device is arranged close to or away from the workpiece receiving device, then the dressing function can be performed, but the setup work becomes more difficult and time-consuming
Solution Approach 1:
The machining tool profiling device is positioned in the lateral direction (Y-axis) at a distance from the workpiece receiving device, rather than directly above or below it. This lateral arrangement allows the dressing tool to access the machining tool from the side, improving accessibility and simplifying setup work compared to vertical arrangements where the dressing tool would be difficult to access.
3Productivity
If multiple workpiece receiving devices are integrated into a rotary table, then productivity can be increased through uninterrupted operation, but the device complexity and costs increase
Solution Approach 1:
Instead of integrating multiple workpiece receiving devices into a single rotary table, the invention positions multiple workpiece receiving devices laterally at different locations along the Y-axis. Each workpiece receiving device has its own stationary position, and the machine base with the workpiece machining device moves laterally to service different workpieces. This segmented arrangement achieves uninterrupted operation through multiple stations without the mechanical complexity of a rotary table.
4Adaptability or versatility
If the machine base linear dual guide is extended to accommodate multiple workpiece receiving devices and machining tool profiling devices, then the machine can perform multiple functions, but the length and footprint of the machine increase
Solution Approach 1:
The machine base linear dual guide is oriented in the lateral Y-direction rather than extending in the longitudinal X-direction. This allows multiple workpiece receiving devices and the machining tool profiling device to be arranged laterally at different Y-coordinates while maintaining a compact longitudinal footprint. The machine base moves laterally along this guide to access different positions, achieving multi-functionality without excessive machine length.
