Dual Worktable Machine Tool for Long Workpiece Machining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing double-spindle machine tools are limited in the maximum length of workpieces they can machine due to their structural constraints, restricting the machining of longer workpieces efficiently.
Innovation Solution
A machine tool design with two separate workpiece tables, each pivotally mounted and adjustable, allowing for larger workpieces to be clamped and machined parallelly, with a common drive unit for synchronous movement and adjustable spindle positions to minimize travel distances and enhance machining efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional double-spindle machine structure is used, then two workpieces can be machined simultaneously, but the maximum length of workpiece that can be machined is limited
Solution Approach 1:
The machine tool is divided into two separate workpiece tables (first workpiece table and second workpiece table), each capable of independent pivotal movement. This segmentation allows each table to accommodate and machine long workpieces independently while maintaining simultaneous machining capability through the common drive unit that synchronizes their movement.
2Adaptability or versatility
If the distance between the first pivot axis and the second pivot axis is increased to accommodate wider workpieces, then the workpiece versatility is improved, but the travel distance of the work spindle increases
Solution Approach 1:
The distance between the first pivot axis and the second pivot axis is made adjustable rather than fixed. The common drive unit enables dynamic adjustment of this distance to match the specific width requirements of different workpieces. This dynamic adaptability allows the machine to accommodate various workpiece widths while minimizing the travel distance of the work spindle by optimizing the table spacing for each machining task.
