Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing tool joint edge burrs from a wheel's cap opening are manual, leading to uneven removal and potential scratching, which can result in corrosion failures and are not suitable for high-precision or continuous production.
Innovation Solution
A device comprising a precision positioning system and a cutter system, featuring L-shaped reverse chamfer cutters, that automatically positions and removes burrs with high accuracy, accounting for coaxiality deviations between the cap opening and center hole, ensuring efficient and precise burr removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual methods are used to remove burrs from the cap opening, then the burrs can be removed, but the internal area of the cap opening is easily scratched and the burrs are not removed uniformly
Solution Approach 1:
The patent replaces manual mechanical burr removal with an automated cutting device that uses a rotating cutter to precisely remove burrs. The device includes a positioning mechanism that accurately locates the cap opening and a cutting mechanism that uniformly removes burrs without scratching the internal area, thereby improving manufacturing precision while eliminating the harmful effects of manual operation.
Solution Approach 2:
The device incorporates an automatic positioning system that self-adjusts to locate the cap opening center and a automated cutting mechanism that performs burr removal without manual intervention. The system includes sensors and control mechanisms that automatically adjust cutting parameters to achieve uniform burr removal while protecting the cap opening surface.
2Productivity
If manual burr removal is used, then flexibility is maintained, but the process is not suitable for continuous production and has low efficiency
Solution Approach 1:
The patent designs a continuous production system where the cutting device can process multiple wheels sequentially without interruption. The device includes an automated feeding and positioning mechanism that continuously presents workpieces to the cutting mechanism, enabling continuous burr removal operation. The system maintains operational flexibility through programmable control that can adjust parameters for different wheel types while sustaining continuous production.
Solution Approach 2:
The device incorporates dynamic positioning mechanisms that can automatically adjust to different wheel positions and orientations. The cutting mechanism includes variable speed control and adjustable cutting parameters that adapt to different workpiece characteristics, maintaining operational flexibility while enabling continuous high-speed production.
3Manufacturing precision
If automated cutting device is designed with precision positioning system, then machining precision is improved, but device complexity increases
Solution Approach 1:
The patent employs a multi-functional positioning system that simultaneously performs multiple functions: locating the cap opening center, compensating for coaxiality deviations, and guiding the cutting mechanism. The positioning device includes adjustable elements that can adapt to different wheel types and tolerance ranges, reducing the need for multiple specialized positioning systems while maintaining high machining precision through integrated functionality.
