Solution Overview

Problem

Existing turret tool posts have complex structures due to the complicated connection of gears, making them difficult to simply turn tools supported by a tool attachment part relative to a turret.

Innovation Solution

A turret tool post with a post body, a turnable turret, and independent tool-attachment-part turning means and turret turning means, where the tool-attachment-part turning means is configured with a drive motor and positioned to oppose the turret turning means, allowing for a simpler structure and flexible installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the tool-attachment-part turning means and turret turning means are integrated with complicated gear connections, then the tool can be turned relative to the turret, but the structure becomes complex and installation space is constrained

Engineering Contradiction:
Improvestructure complexityVSAvoidtool turning capability
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The patent divides the turning mechanism into two independent parts: turret turning means for rotating the turret, and tool-attachment-part turning means for rotating the tool attachment part independently. This segmentation eliminates the need for complicated gear connections while maintaining the ability to turn the tool relative to the turret, thereby reducing structural complexity without sacrificing operational capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent extracts the tool-attachment-part turning function from the integrated gear system and provides it with an independent drive mechanism. This extraction simplifies the overall structure by removing the complex gear connections while ensuring that the tool can still be turned relative to the turret through the independent tool-attachment-part turning means.

Inventive Principle:
Principle #2Taking out (Extraction)

2Volume of moving object

If the tool-attachment-part turning means is attached inside the turret turning drive shaft, then space is utilized, but the structure becomes complicated

Engineering Contradiction:
Improveinstallation space utilizationVSAvoidstructural complexity
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The patent segments the turning mechanisms into independent components with separate drive sources. The tool-attachment-part turning means is positioned independently rather than being attached inside the turret turning drive shaft, which reduces structural complexity while still utilizing available space efficiently through proper arrangement of the independent components.

Inventive Principle:
Principle #1Segmentation

AI summary

This disclosure provides a turret tool post that can turn a tool supported by a tool attachment part relative to a turret with a simple structure. A turret tool post (10) includes a turret (12) turnably supported by a post body (11), turret turning means having a turret turning shaft (23) and the like to turn the turret (12), a tool attachment part (15) turnably holding a rotatable tool (14a) and attached to the turret (12), and tool-attachment-part turning means turning the tool attachment part (15) to turn the rotatable tool (14a). The tool-attachment-part turning means and the turret turning means are provided independently and arranged to face each other. The tool-attachment-part turning means includes a tool turning motor (41) installed inside the turret (12) and an attachment-part transmission shaft (90) connected to the tool turning motor (41).
