Independent Multi-Axis Machining Center for Simultaneous Part Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-axis machining centers are limited in processing different shaped parts simultaneously due to non-independent movement of processing heads and tool changers, leading to complex tool changing structures and increased processing time.
Innovation Solution
A multi-axis machining center design where multiple processing tables and heads can move independently in both vertical and left-right directions, with tool changers positioned on either side to simplify the tool changing process and reduce tool change time, allowing for simultaneous processing of different parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple spindles are arranged in one body with shared movement mechanism, then structural complexity is reduced, but processing heads cannot move independently to process different shaped parts simultaneously
Solution Approach 1:
The machining center is divided into multiple independent processing units, each with its own processing head and table. The first processing head and first table form one independent unit, while the second processing head and second table form another. This segmentation allows each unit to move and process independently, enabling simultaneous processing of different shaped parts while maintaining manageable structural complexity through modular design.
2Quantity of substance
If tool changers are positioned at the rear of the support frame, then tool storage capacity is increased, but tool changing structure becomes complicated and time is increased
Solution Approach 1:
The tool changers are repositioned from the rear horizontal position to vertical positions above each processing table. The first tool changer is located above the first table and the second tool changer is located above the second table. This dimensional change allows tools to be changed vertically from above, simplifying the tool changing structure and reducing time while maintaining adequate tool storage capacity through vertical arrangement.
3Stability of the object's composition
If processing heads are fixed in position, then structural stability is improved, but processing flexibility and productivity are reduced
Solution Approach 1:
The processing heads are made dynamically movable along the X-axis while maintaining vertical stability. The first processing head can move left and right along the X-axis independently, as can the second processing head. This dynamic capability allows the heads to reach different work positions and process various shaped parts efficiently, while the vertical support structure maintains overall structural stability during operation.
4Device complexity
If single table is used, then device simplicity is maintained, but ability to process multiple different parts simultaneously is limited
Solution Approach 1:
The single table is segmented into two independent tables: the first table and the second table. Each table can be positioned and processed independently by its corresponding processing head. This segmentation enables simultaneous processing of multiple different parts on the same level, improving productivity while maintaining relative device simplicity through the use of replicated modular components.
