Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tool changing mechanisms for machine tools, particularly in fine machining like blisk machining, are complex and inefficient due to the need for precise rotation and alignment of tools, which complicates the process and affects stability and maintenance.
Innovation Solution
A bevel swing head interpolation tool changing mechanism that utilizes a bed, sliding table, column, ram, and tool magazine, allowing the swing head to move along multiple axes with an included angle of 30°-60°, enabling quick and convenient tool changing through coordinated movement of linear axes without complex equipment like manipulators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional tool changing mechanism is used for bevel swing head machining, then the tool can be changed, but the structure becomes complex and maintenance becomes difficult
Solution Approach 1:
The patent combines the tool changing function with the existing linear axes (X, Y, Z) and swing head rotation (B-axis) of the machine tool. By merging these existing movements into a coordinated interpolation sequence, the tool changing operation is achieved without adding complex dedicated changing mechanisms, thus improving ease of operation while avoiding increased device complexity
Solution Approach 2:
The linear axes and swing head, originally designed for machining operations, are made multi-functional by programming them to perform tool changing tasks through interpolation movement. This allows the same mechanical components to serve dual purposes: both machining and tool changing, eliminating the need for separate specialized tool changing equipment
2Manufacturing precision
If precise rotation and alignment of tools is implemented, then machining precision is improved, but the control process becomes complicated and stability decreases
Solution Approach 1:
The patent employs interpolation control that coordinates the movement of multiple axes (X, Y, Z, and B-axis) with precise feedback mechanisms. The control system continuously monitors the positions of all involved axes and adjusts their movements to maintain accurate alignment between the tool and swing head axis throughout the tool changing process, ensuring both precision and stability
Solution Approach 2:
The tool changing process is implemented as a dynamic coordinated movement of multiple axes rather than a static alignment procedure. The interpolation control enables real-time adjustment of axis positions and speeds during the tool changing sequence, allowing the system to adapt to minor variations and maintain precision while simplifying the overall control logic through automated coordination
3Extent of automation
If manipulators and complex equipment are used for tool changing, then automated tool changing is achieved, but the device complexity increases and maintenance becomes difficult
Solution Approach 1:
The system uses the machine tool's own existing axes and swing head to perform the tool changing operation autonomously through programmed interpolation movement. The linear axes and B-axis rotation work together in a coordinated sequence to automatically position, align, and exchange tools without requiring external manipulators or complex changing equipment, achieving automation while keeping the device structure simple and easy to maintain
