Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chamfer tools can only perform chamfering operations on either the internal or external ends of tubes, requiring multiple tools and suffering from inefficient chip removal, leading to tool wear and inconvenience.
Innovation Solution
A chamfer tool with a main body, driving shaft, and milling members, featuring first and second blades protruding from the outer and inner surfaces respectively, and non-coplanar chip removal surfaces to facilitate both internal and external chamfering operations while preventing chip accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional chamfer tools are used, then chamfering operation can be performed, but multiple tools are required for internal and external chamfering
Solution Approach 1:
The patent combines both internal chamfering and external chamfering capabilities into a single tool body. The tool integrates multiple milling members with different blade configurations (first blades for external chamfering, second blades for internal chamfering) on the same main body, eliminating the need for separate internal and external chamfering tools.
Solution Approach 2:
The tool body is designed as a universal chamfering tool that can perform both internal and external chamfering operations. By equipping the single tool with multiple types of milling members having different blade arrangements, it achieves multi-functionality and can adapt to different chamfering requirements without needing multiple specialized tools.
2Productivity
If conventional chamfer tools are used, then chamfering operation can be performed, but chip accumulation occurs leading to tool wear
Solution Approach 1:
The patent extracts and removes chips from the chamfering area through specifically designed chip removal surfaces. These surfaces are configured to guide and extract chips away from the milling members and tool body during rotation, preventing chip accumulation that would otherwise cause tool wear and reduce reliability.
Solution Approach 2:
The patent converts the harmful effect of chip accumulation into a beneficial chip removal mechanism. By designing chip removal surfaces that utilize the rotational motion and cutting forces, the tool actively directs chips away from critical areas, transforming what would be a harmful accumulation into an efficient chip ejection system that protects the tool.

AI summary
A chamfer tool includes a main body, a driving shaft and a plurality of milling members. The main body, which rotates along an axis, has an inner surface and an outer surface located on opposite sides thereof; wherein the main body further has a plurality of mounting portions, each of which is connected to the inner surface and outer surface. The driving shaft is fixed to the main body to drive the main body to rotate. Each of the milling members has a first blade and a second blade, wherein the milling members are mounted on the mounting portions of the main body with the first blades protruding from the outer surface of the main body and the second blades protruding from the inner surface of the main body.
