Multi-Tool Chamfering Head for Diverse Toothed Workpiece Geometries
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chamfering devices lack flexibility to effectively handle the diverse geometries and sizes of toothed workpieces, such as gears and shafts, as a single type of chamfering tool may not be suitable for all workpieces, particularly when dealing with different gear sizes and tooth geometries.
Innovation Solution
A multi-axis and multi-tool chamfering device with a chamfering head that includes two axes of rotation for different types of chamfering tools, allowing for various material removal methods, where the first and second axes of rotation are preferably perpendicular to each other, enabling the use of different chamfering tools for distinct chamfering operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single type of chamfering tool is used, then the device complexity is reduced, but the adaptability to different workpiece geometries deteriorates
Solution Approach 1:
The chamfering device incorporates multiple chamfering tools of different types (e.g., fly cutter, milling tool, hob, profile cutter, grinding wheel, skiving cutter, deburring wheel) within a single device, enabling it to handle diverse workpiece geometries including gear edges and root portions with different sizes and tooth geometries, thus achieving multi-functionality and universality
Solution Approach 2:
The chamfering head is divided into multiple independent tool stations, each equipped with a specific type of chamfering tool. This segmentation allows each tool to be optimized for particular workpiece features while the overall system maintains flexibility through selective tool usage
2Adaptability or versatility
If multiple axes of rotation are added, then the capability to handle diverse workpiece types is improved, but the device complexity increases
Solution Approach 1:
The chamfering head incorporates multiple axes of rotation (first axis for radial/face chamfering, second axis for axial/longitudinal chamfering) that are preferably perpendicular to each other. This multi-dimensional arrangement enables the device to access and chamfer different surfaces of toothed workpieces from multiple orientations, significantly expanding capability to handle diverse workpiece types
3Adaptability or versatility
If different material removal methods are implemented, then the flexibility for various chamfering operations is improved, but the device complexity increases
Solution Approach 1:
The device integrates multiple material removal methods including material subtraction (cutting with fly cutter, milling tool, hob, profile cutter, skiving cutter), material abrasion (grinding with grinding wheel), and material deformation (rolling with deburring wheel). This multi-method approach provides flexibility for various chamfering operations on different workpiece features

AI summary
A toothed workpiece chamfering device having a chamfering head (2) which includes a first axis of rotation (B) for rotation of a first chamfering tool (6) and a second axis of rotation (T) for rotation of a second chamfering tool (8) wherein the first and second chamfering tools are of different types and their respective material removal methods are also different from one another. Preferably, the first and second axes of rotation are not coincident with one another and in a more preferred arrangement, the first tool axis and the second tool axis are arranged perpendicularly to one another.
