Sliding Tool Holder Structure for Detachable Processing Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional deburring tools lack a simple and efficient mechanism for sliding tools axially relative to the body while maintaining a detachable tool holder structure.
Innovation Solution
A processing tool design featuring a spindle with a tool holder holding hole, a cover that reciprocates between processing and detachable positions, and an elastic member to urge the tool holder, allowing for axial sliding and easy attachment/detachment of tools, including a deburring tool, drilling tool, or threading tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional deburring tool structure is used with spring member and initial length adjusting means, then pressing force can be adjusted, but the structure becomes complex and tool attachment/detachment is cumbersome
Solution Approach 1:
The tool holder is segmented into a main body and a detachable tool inserting portion, allowing the tool to be easily attached and detached while keeping the main structure simple. The cover is also segmented to reciprocate between processing and detachable positions, enabling easy tool holder removal without complex adjustment mechanisms.
Solution Approach 2:
The initial length adjusting means and spring member are extracted from the conventional structure and replaced with a simpler elastic member positioned between the tool holder and cover. This extraction eliminates complex adjustment mechanisms while maintaining the essential function of pressing force application.
2Ease of operation
If the cover is designed to reciprocate between processing and detachable positions, then tool holder removal is simplified, but the mechanism requires precise positioning and anti-rotation features
Solution Approach 1:
The cover includes an asymmetric relief portion that receives an asymmetric anti-rotation protrusion on the spindle. This asymmetric design ensures the cover cannot rotate relative to the spindle while allowing smooth reciprocation between processing and detachable positions, combining ease of operation with reliable positioning.
Solution Approach 2:
The relief portion acts as an intermediary feature between the cover and spindle, providing a precise mating interface that guides the cover's reciprocating motion and prevents rotation. This intermediary structure ensures reliable positioning without adding complex anti-rotation mechanisms.
3Adaptability or versatility
If the elastic member is positioned between the tool holder and body, then axial sliding is enabled, but tool alignment and balance may be affected during processing
Solution Approach 1:
The elastic member is positioned between the tool holder and cover rather than between the tool holder and body, changing the dimensional arrangement. This positioning allows axial sliding capability while the cover's reciprocating motion maintains tool alignment during processing, as the elastic member's force is applied through the cover's pressing surface.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the tool holder to be easily removed and replaced, allowing for quick tool changes and improved operational efficiency by maintaining the tool's alignment and balance during processing, even when dealing with varying workpiece sizes and burr heights.
Implementation Method 1
an elastic member disposed between the first spring holding hole and the tool holder holding hole to urge the tool holder toward distal end
