Dual Turnable Tool Post for Compact Multi-Operation Machining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional machine tools have limitations in the variety of operations they can perform due to restrictions on the number and type of tools attachable to the turnable holder, leading to a limited range of cutting edge directions, and larger turnable holders increase machine size.
Innovation Solution
A compact machine tool design featuring a tool post with two turnable holders on perpendicular axes, allowing multiple tools to be attached and reducing the machine's size by optimizing turning space, with a common motor driving both holders and a brake maintaining the second holder's angle for enhanced accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a larger turnable holder with more tool mounting parts is used to increase the variety of operations, then the number of attachable tools increases, but the turning space occupied increases and machine size increases
Solution Approach 1:
The turnable holder is divided into multiple independent turnable holders (first turnable holder and second turnable holder), each capable of rotating on different turning axes. This segmentation allows each holder to be compact while collectively providing multiple tool mounting parts and operation varieties, resolving the contradiction between versatility and size.
Solution Approach 2:
The invention introduces multiple turning axes (first turning axis and second turning axis perpendicular to each other) to create a multi-dimensional tool positioning system. This allows tools to be directed in various directions without requiring a single large turnable holder, thus maintaining compact size while achieving operational versatility.
2Adaptability or versatility
If multiple turnable holders with different turning axes are introduced to increase operational variety, then the cutting edge directions are improved, but the device complexity increases
Solution Approach 1:
Multiple turnable holders are merged into a single integrated tool post structure, sharing common mounting and support mechanisms. This consolidation reduces overall structural complexity while maintaining the ability to provide multiple cutting edge directions through coordinated rotation of the individual holders.
Solution Approach 2:
Each turnable holder is designed with universal functionality to mount different tool types (including rotary tools and thread whirling tools) and perform multiple operations. This multi-functionality reduces the need for specialized components for each operation type, thereby simplifying the overall device structure.

AI summary
A machine tool includes a spindle capable of holding a workpiece and rotatable on a spindle axis and a tool post on which a tool is attachable to machine the workpiece held by the spindle. The tool post includes a first turnable holder turnable on a first turning axis perpendicular to the spindle axis. The first turnable holder has a first tool unit mounting part where a rotary tool is attachable. The tool post further includes a second turnable holder turnable on a second turning axis perpendicular to the spindle axis and different from the first turning axis. The second turnable holder has a second whirling tool mounting part where a thread whirling tool is attachable.
