Wheel Deburring Device Segmented Brush Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional deburring methods for wheels are ineffective in removing corner burrs from flanges and rims due to low linear velocity at the central position of large-disc brushes, leading to suboptimal results in the painting process.
Innovation Solution
A wheel deburring device with a unique design where an outer ring and inner ring of a lower brush rotate separately, and round brushes autorotate, allowing for effective removal of burrs from the front surface and back cavity of wheels, utilizing a complex system of motors, pulleys, and synchronized belts to ensure precise and efficient deburring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a large-disc brush is used for deburring, then the brush can cover a large area, but the linear velocity at the central position is low resulting in poor deburring effect on corner burrs
Solution Approach 1:
The lower brush is segmented into an outer ring and an inner ring that rotate separately at different speeds. The outer ring rotates faster to provide high linear velocity for removing corner burrs, while the inner ring rotates at a different speed for effective deburring of other areas. This segmentation resolves the contradiction by allowing different regions of the brush to operate at optimal velocities for their specific deburring tasks.
Solution Approach 2:
Different regions of the brush are given different rotational velocities tailored to their specific deburring needs. The outer ring receives higher rotational velocity for corner burr removal, while the inner ring operates at a different velocity for its designated area. This local quality approach ensures each part of the brush system operates at the optimal speed for its specific function, resolving the speed-coverage area contradiction.
2Reliability
If round brushes are made to autorotate, then deburring effectiveness is improved, but the device complexity increases due to additional mechanisms
Solution Approach 1:
The round brushes are designed to autorotate automatically through a gear mechanism that converts the rotational motion from the main drive into self-rotation of the brushes. This self-service mechanism eliminates the need for external actuators or complex control systems for each brush, achieving reliable deburring effectiveness while keeping the added complexity minimal and automated.
3Manufacturing precision
If the outer ring and inner ring rotate separately, then corner burrs can be excellently removed, but the device complexity increases due to additional drive mechanisms
Solution Approach 1:
The lower brush is divided into separately rotating outer and inner rings, each capable of independent rotational motion. This segmentation allows the outer ring to achieve the high linear velocity needed for effective corner burr removal, while the inner ring operates independently for its designated area, thereby achieving high manufacturing precision for deburring quality.
Solution Approach 2:
Multiple drive mechanisms for the outer ring and inner ring are merged into a unified drive system that uses a single motor and gear mechanism to control both rings. This merging approach achieves the complex rotational control needed for high-quality corner burr removal while minimizing the number of separate components and control systems, thereby reducing overall device complexity.
