Machining Tool Axis Swivel for End-Cut Work Wheel Tooth Edges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for machining tooth edges on end-cut work wheels are inflexible and require multiple tools and adjustments, leading to increased machining time and limited tool diameter due to the joint arrangement of machining and hobbing tools on the same shaft.
Innovation Solution
The tool axis of rotation is independently adjustable, allowing opposite cutting directions between machining positions without changing the direction of rotation, enabling a single machining tool to efficiently chamfer or deburr both end faces with a freely selectable diameter, and allowing machining during primary processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the machining tool and hobbing cutter are clamped on the same shaft, then the device structure is simplified, but the tool diameter is limited and clamping collisions occur
Solution Approach 1:
The patent divides the machining system into two independent parts: the hobbing cutter mounted on the hobbing shaft and the machining tool mounted on the machining shaft. This segmentation allows each tool to be independently selected and positioned, eliminating the diameter limitations and clamping collisions that would occur if both tools were mounted on the same shaft.
2Ease of operation
If two chamfering tools with opposite cutting directions are clamped on the shaft, then the cutting direction can run from inside to outside at both end faces, but the device complexity increases
Solution Approach 1:
The patent employs a swivel mechanism that allows the machining tool to dynamically change its cutting direction by rotating between two working positions. This dynamic adjustment enables a single machining tool to achieve inside-to-outside cutting direction at both end faces, eliminating the need for two separate tools with opposite cutting directions.
3Adaptability or versatility
If the shaft is adjusted in space between machining positions, then the machining can be performed on both end faces, but the machining time increases
Solution Approach 1:
The patent pre-configures the machining tool with a swivel mechanism that allows rapid switching between the two working positions. This preliminary design of the positioning mechanism enables quick transitions between machining positions without requiring time-consuming shaft adjustments, thereby reducing total machining time while maintaining the ability to machine both end faces.
4Device complexity
If the joint arrangement on the same shaft is used, then the device structure is simplified, but the tool selection flexibility is limited
Solution Approach 1:
By separating the machining tool and hobbing cutter onto different shafts, the patent enables independent selection and optimization of each tool. The machining tool diameter and type can be freely chosen based on specific machining requirements without being constrained by the hobbing cutter dimensions, thereby significantly improving tool selection flexibility.

AI summary
A method and a device for machining the tooth edges (23, 25) developed between each end face (22, 24) and the tooth flanks (26, 27) of end-cut work wheels (2). The axis of rotation (20) of the spindle that carries the machining tool (21) is displaced around an orthogonal swivel axis (16) relative to the tool axis of rotation so that the cutting directions are opposite to each other with respect to the work wheel (2) in the machining of the lower tooth edges (23) and the upper tooth edges (25).
