Two-Stage Wheel Blank Flash Removal for Coaxial Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wheel manufacturing automation technologies face challenges in ensuring the surface quality of wheel blanks is flat and free of flashes, which affects accurate grasping and processing, particularly in feeding and discharging operations.
Innovation Solution
A device with two-layer turnover mechanisms and milling cutters is designed to remove flashes from the front face, end face, inner rim, and outer rim of wheel blanks, ensuring coaxial processing and orderly takt connection by positioning and clamping the wheel for precise milling operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a manipulator is used for feeding and discharging during wheel machining, then automation level is improved, but the requirement for blank surface quality (flat and flash-free) becomes more stringent
Solution Approach 1:
The patent applies preliminary action by removing flashes from the wheel blank before machining operations. The device includes milling cutters that eliminate flashes on the front face, end face, inner rim, and outer rim of the wheel blank in advance, ensuring the surface is flat and free of defects before the manipulator grasps and processes the blank.
2Device complexity
If flashes are not removed from the wheel blank surface, then processing steps are reduced, but the accuracy of manipulator grasping and positioning deteriorates
Solution Approach 1:
The device removes flashes preliminarily before manipulator operation, ensuring the blank surface is clean and flat. This preliminary flash removal enables the manipulator to accurately grasp and position the wheel blank, improving measurement and positioning accuracy without adding significant complexity to the overall process.
3Manufacturing precision
If multiple flash removal operations are performed on different surfaces, then surface quality is improved, but processing time increases
Solution Approach 1:
The patent merges multiple flash removal operations into a single integrated device. The machine tool can perform flash removal on the front face, end face, inner rim, and outer rim of the wheel blank in sequence without requiring separate operations or repositioning, thereby improving surface quality while minimizing processing time.
Solution Approach 2:
The device maintains continuous useful action by enabling flash removal operations to proceed sequentially on different surfaces of the wheel blank without interruption. The milling cutters are positioned and operated in a coordinated manner to eliminate flashes on all required surfaces in a continuous process, maximizing productivity while ensuring high surface quality.

AI summary
A device for removing flashes of a wheel blank includes two layers of turnover mechanisms, wherein the lower-layer turnover mechanism realizes the initial positioning of a wheel and has the function of removing the flashes at both the inner side and the outer side of an inner rim of the wheel, and the upper-layer turnover mechanism realizes the secondary positioning of the wheel and has the function of removing the flashes on the outer rim side. By means of the two layers of turnover mechanisms, the flashes on the front face and end face of a wheel blank outer rim wheel lip, and the inner side and outer side of the inner rim are removed, and coaxial processing conversion and orderly takt connection are ensured. The disclosure also provides a method for removing flashes of a wheel blank.
