Deburring Tool Gear-Spring Mechanism for Uniform Cutting Depth
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 inconsistent deburring processes.
Innovation Solution
A deburring tool with a drive gear and reciprocating shaft mechanism that includes a saw blade-shaped first tooth and a driven gear with a second tooth, where the driven gear slides with the drive gear to transmit rotating torque and adjust cutting depth, using springs to control the tool's movement and maintain uniform cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional deburring tool with a spring pressing mechanism is used, then the tool can apply cutting force to the workpiece, but the cutting depth becomes inconsistent depending on workpiece shape and position
Solution Approach 1:
The patent applies the dynamics principle by making the cutting tool holder movable along the axial direction through a gear mechanism. The cutting tool's position is dynamically adjusted based on the workpiece geometry, allowing consistent cutting depth across different workpiece shapes and positions. The spring mechanism provides dynamic force application while the gear system enables precise positional control.
Solution Approach 2:
The patent implements feedback through the interaction between the cutting tool and workpiece. As the cutting tool contacts the workpiece surface, the reaction force is transmitted through the gear mechanism to automatically adjust the cutting depth. This feedback loop ensures consistent cutting depth by allowing the system to self-correct based on actual workpiece geometry.
2Force
If the cutting tool is pressed against the workpiece with a spring, then cutting force is applied, but excessive or insufficient shaving occurs depending on workpiece position
Solution Approach 1:
The patent uses dynamics by allowing the cutting tool holder to move axially while maintaining cutting force through the spring mechanism. This dynamic adjustment ensures that the cutting force is consistently applied regardless of workpiece position or shape, preventing both excessive and insufficient shaving.
Solution Approach 2:
The patent applies self-service through the automatic adjustment mechanism. The gear system and spring work together to automatically maintain optimal cutting force and depth without external intervention. The system self-regulates based on the workpiece geometry, ensuring uniform shaving across different positions.
3Device complexity
If a simple spring pressing mechanism is used, then the device structure remains simple, but the deburring process cannot be uniform across different workpiece positions
Solution Approach 1:
The patent introduces dynamic adjustment capability through the gear mechanism while maintaining relative structural simplicity. The cutting tool holder can move axially to adapt to different workpiece positions, achieving uniform deburring without significantly complicating the overall device structure.
Solution Approach 2:
The patent uses the gear mechanism as an intermediary between the spring pressing force and the cutting tool position. This intermediary component translates the spring's axial force into precise positional adjustment of the cutting tool, enabling uniform deburring while keeping the device structure manageable.
