Spring-Loaded Deburring Tool for Uniform Cutting Torque
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional deburring tools often either excessively or insufficiently shave workpieces depending on their shape and position, leading to non-uniform deburring processes.
Innovation Solution
A deburring tool and method featuring a case with a shank and cylinder, a hollow sleeve, drive gear, reciprocating shaft, tool holder, and springs that allow for uniform cutting by rotating the case and sleeve with the spindle, transmitting torque to the tip tool, and moving the reciprocating shaft to adjust cutting based on workpiece contact, ensuring consistent deburring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional deburring tool with a spring-loaded cutting tool holding unit is used, then the tool can apply cutting force to the workpiece, but the deburring result becomes non-uniform depending on workpiece shape and position
Solution Approach 1:
The invention employs dynamic mechanisms including a reciprocating shaft that moves back and forth, a tool holder that can rotate and reciprocate, and springs that provide adaptive force. These dynamic elements allow the cutting tool to automatically adjust its position and cutting depth based on workpiece geometry, achieving uniform deburring across different shapes and positions
Solution Approach 2:
The spring-loaded tool holder acts as a feedback mechanism that senses workpiece contact and automatically adjusts cutting force. When the cutting tool contacts the workpiece, the spring compresses and modulates the applied force, providing real-time adaptation to maintain consistent deburring quality regardless of workpiece variations
2Force
If the cutting tool holding unit is pressed against the workpiece with a spring, then cutting force is applied, but excessive or insufficient shaving occurs depending on workpiece characteristics
Solution Approach 1:
The reciprocating shaft mechanism creates dynamic motion that alternates between cutting and retraction phases. This dynamic action allows the cutting tool to engage and disengage from the workpiece in a controlled manner, preventing both excessive force application and insufficient cutting, thereby achieving consistent cutting depth across varying workpiece conditions
Solution Approach 2:
The tool holder's rotational and reciprocating motion creates periodic cutting action. This periodic engagement and disengagement of the cutting tool allows for controlled material removal with consistent depth, as the tool naturally cycles through different positions and force applications during each rotation cycle

Function Achieved in This Case
The deburring tool achieves uniform deburring by maintaining constant cutting torque and adjusting cutting amounts regardless of workpiece position, resulting in a smooth machined surface and minimizing tool and workpiece damage.
