Wheel Burr Removal Alignment for Coaxial Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for removing circumferential burrs from wheels are inefficient due to coaxial deviation between burrs produced in different turning processes, leading to poor roundness and uneven paint coverage, which requires manual correction and is prone to corrosion.
Innovation Solution
A device comprising a frame, cylinders, servo motors, rotating disks, and sensors that automatically positions and clamps the wheel, adjusts the burr cutters to match the wheel's center, and synchronizes the rotation of cutters with the burr centers to remove burrs with high precision from the flange, outer rim, and riser edges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual removal of circumferential burrs is used, then flexibility in handling different burr positions is maintained, but manufacturing precision deteriorates due to inability to ensure roundness
Solution Approach 1:
The patent replaces manual mechanical removal with an automated cutting device that uses a rotating cutter to automatically remove burrs. The device includes a cutting tool holder, cutter, and positioning mechanism that automatically adjusts to the wheel's geometry, eliminating the need for manual operation while ensuring consistent roundness and precision in burr removal.
2Productivity
If burrs are removed after first turning and second turning, then all circumferential burrs can be addressed, but manufacturing precision deteriorates due to coaxial deviation between burrs from different turning processes
Solution Approach 1:
The patent performs preliminary positioning and measurement of the wheel's actual geometry before burr removal. The device measures the wheel's radius and center position, then pre-adjusts the cutter's position and orientation to match the measured geometry. This preliminary action compensates for coaxial deviations from previous turning processes, ensuring that the cutter is correctly positioned to remove all circumferential burrs with high precision.
3Productivity
If automatic equipment is used for burr removal, then productivity improves through automation, but device complexity increases to achieve high-precision positioning and cutter synchronization
Solution Approach 1:
The patent implements a self-adjusting positioning system where the device automatically measures the wheel's geometry and adjusts its own cutter position and orientation without external intervention. The system uses sensors to detect the wheel's radius and center, then automatically compensates for deviations by adjusting the cutter holder's position. This self-service capability achieves high-precision automation while minimizing the need for complex external positioning mechanisms.

AI summary
A device for removing circumferential burrs of a wheel with high precision includes an electric cylinder, a lifting table, guide rails, an electric cylinder, a sliding block, a plurality of sensors, a rim burr cutter, a riser burr cutter, and the like. The device can simultaneously remove circumferential burrs from the flange edge, the outer rim and the riser slot edge, which eliminates the error caused by coaxial degree deviation, so that the rotating center of the cutters coincides with the circumferential center of the burrs. The device is configured to provide high-precision removal of burrs from the flange edge, and high-precision removal of burrs from the outer rim and the riser.
