Wheel Burr Removal Alignment for Coaxial Deviation Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for removing circumferential burrs from wheels, particularly those produced during the turning process, face challenges in ensuring high precision due to coaxial deviation issues, leading to poor roundness and uneven paint coverage, which necessitate automatic equipment for removal.
Innovation Solution
A device comprising a frame with lower and upper cylinders, guide rails, servo motors, rotating disks, and sensors that positions and clamps the wheel to align the burr cutters coaxially with the wheel's center, allowing for simultaneous high-precision removal of burrs from the flange edge, outer rim, and riser slot edge, while adjusting for different wheel sizes and configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual removal of circumferential burrs is used, then the device complexity is low, but the manufacturing precision of burr removal is poor due to inability to ensure roundness
Solution Approach 1:
The patent replaces manual mechanical removal with an automated cutting system that uses sensors to detect burr positions and coordinates to control cutter movement, achieving high-precision removal while maintaining operational simplicity through automation
Solution Approach 2:
The system automatically detects burr positions using sensors and calculates coordination data, then autonomously controls the cutters to remove burrs without manual intervention, ensuring consistent roundness and precision
2Manufacturing precision
If automatic equipment is introduced for burr removal, then the manufacturing precision improves, but the device complexity increases
Solution Approach 1:
The automatic burr removal system is divided into independent functional modules: sensor detection units, coordinate calculation units, and cutter execution units, allowing the complex system to be managed and maintained as separate, manageable components
Solution Approach 2:
The coordinate calculation unit serves multiple functions by processing data from different sensors and generating control signals for multiple cutters, reducing overall system complexity while maintaining high precision across all burr removal operations
3Device complexity
If coaxial cutters are used for burr removal, then the device complexity is low, but the manufacturing precision deteriorates due to coaxial deviation from two-lathe turning
Solution Approach 1:
Sensors detect the actual positions of circumferential burrs produced by two-lathe turning, and the system uses this feedback to calculate coordination data that compensates for coaxial deviations, ensuring precise cutter alignment without requiring complex coaxial cutter configurations
Solution Approach 2:
The system performs preliminary detection of burr positions and calculates the coordination data before the actual cutting operation, allowing the cutters to be precisely positioned to account for coaxial deviations from the turning process
4Manufacturing precision
If high-precision burr removal is achieved through coordinate control, then the manufacturing precision improves, but the productivity decreases due to additional positioning time
Solution Approach 1:
The sensor detection, coordinate calculation, and cutter execution operations are performed in continuous sequence without interruption, eliminating idle positioning time and maintaining high precision while maximizing productivity

AI summary
Disclosed is a device for removing circumferential burrs of a wheel with high precision, consisting of three electric cylinders (21), three lifting tables (22, 28, 33), three guide rails (23, 30, 35), three sliding blocks (26, 31, 36), three sensors (27, 32, 37), a rim burr cutter (51), a riser burr cutter (55) and flange burr cutters (13) The shared centre of rotation of the rim burr cutter (51) and the riser burr cutter (51) can be offset from the centre of rotation of the flange burr cutters (13) as a result of the capture of three points on the bead seat of the wheel by the sensors (27, 32, 37) so as to be able to eliminate the error caused by coaxial deviation between the first and second turning operations during manufacture of the wheel, such that the centre of rotation of each cutter (13, 51, 55) coincides with the geometric center point of each of the burrs. The device can remove circumferential burrs from the flange edge, the outer rim and the riser slot edge in one operation, even though the respective burrs may not be concentric with each other.
