Vehicle Wheel Burr Removal Device with Precision Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for removing tool joint edge burrs from vehicle wheels are inefficient and lack precision, particularly in ensuring coaxiality between the outer rim and cap slot edge, leading to deviations and residue issues during machining.
Innovation Solution
A device comprising a precision positioning system with a combination of motors, guide rails, ball screws, and cutting blades that automatically aligns the vehicle wheel to superpose the cutter's center with the burr part, allowing for simultaneous removal of burrs on the outer rim and cap slot edge using a pyramid cutter and rotating blades.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If two separate lathes are used for machining the outer rim and cap slot edge, then the machining operations can be completed, but coaxiality deviations occur between the inner rim and outer rim, leading to positioning errors and burr removal inconsistencies
Solution Approach 1:
The patent combines the machining operations for the outer rim and cap slot edge into a single lathe setup with a unified positioning system. The positioning device establishes a common reference axis that simultaneously controls both machining operations, eliminating the coaxiality deviations that occur when using two separate lathes. This merging of operations around a single precision positioning center ensures consistent alignment between the inner rim and outer rim features.
2Manufacturing precision
If precision positioning is implemented using the cap seam allowance, then the rotating center of the cutter can be superposed with the burr part, but the process becomes time-consuming and reduces productivity
Solution Approach 1:
The positioning device performs preliminary precision positioning before the burr removal operation by establishing the correct rotational axis and cutter position in advance. The system pre-aligns the cutter with the cap slot edge and outer rim burr locations using precision mechanical positioning elements, so that when the actual burr removal begins, the cutter is already correctly positioned. This eliminates the need for time-consuming adjustments during the machining process itself.
Solution Approach 2:
The positioning system uses the wheel's own geometric features (cap slot edge and outer rim) as self-referencing elements to automatically establish the correct positioning axis. The device leverages the inherent coaxiality of these features to self-position the cutter without requiring external measurement or manual adjustment, thereby maintaining high precision while improving operational efficiency.
3Ease of manufacture
If the cutter rotating center is not superposed with the burr part center, then the machining process is simpler, but burr residue and non-uniform results occur on the outer rim and cap slot corners
Solution Approach 1:
The positioning device introduces precision mechanical intermediaries (positioning elements, reference surfaces, and alignment mechanisms) that mediate between the simple rotational motion of the cutter and the precise positioning requirement. These intermediaries translate the rotational movement into accurately superposed cutter-burr alignment without complicating the fundamental cutting action, thereby maintaining ease of manufacture while achieving high precision burr removal.
