Rotating Multi-Insert Tool Holder for Machine Tools

Solution Overview

Problem

Conventional machine tools require a long time for tool holder replacement, leading to increased costs and potential precision issues due to minute differences in machining distances caused by individual tool holders.

Innovation Solution

A machine tool design featuring a ram spindle with a tool holder that includes multiple inserts, allowing for rapid and precise machining by clamping and rotating the tool holder using an actuator unit, reducing the need for multiple tool holders and improving productivity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple tool holders are used for different inserts, then machining versatility is improved, but replacement time increases and productivity decreases

Engineering Contradiction:

Improvemachining versatilityVSAvoidreplacement time

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent combines multiple inserts into a single tool holder assembly that can be rapidly exchanged. Instead of having separate tool holders for each insert, the invention integrates multiple inserts (e.g., 4 inserts) into one unified tool holder that rotates to present different inserts to the machining position, reducing the number of replacements needed while maintaining versatility.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The tool holder is designed with rotational capability, allowing dynamic switching between different inserts during machining operations. The actuator unit enables the tool holder to rotate and present different inserts as needed, providing adaptability without requiring multiple static tool holder replacements.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If multiple tool holders are used for different inserts, then machining versatility is improved, but the number of tool holders increases and costs increase

Engineering Contradiction:

Improvemachining versatilityVSAvoidnumber of tool holders

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent combines multiple inserts into a single tool holder assembly that can be rapidly exchanged. Instead of having separate tool holders for each insert, the invention integrates multiple inserts (e.g., 4 inserts) into one unified tool holder that rotates to present different inserts to the machining position, reducing the number of replacements needed while maintaining versatility.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The tool holder is designed as a multi-functional component that can accommodate and present multiple different inserts through rotation. This universal tool holder design eliminates the need for multiple specialized tool holders, reducing inventory requirements while maintaining the ability to perform various machining operations.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If individual tool holders are used, then ease of replacement is improved, but machining precision decreases due to minute differences in machining distances

Engineering Contradiction:

Improveease of replacementVSAvoidmachining precision

Core Design Contradiction:
