Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current aluminum alloy wheel machining process faces challenges in precision connection between first-stage and second-stage turning, leading to deviations in coaxiality and increased rejection rates due to the lack of integrated equipment for high-precision matching of central holes and mandrels.
Innovation Solution
The integration of first-stage and second-stage turning into a single piece of equipment using a lathe bed, servo motors, guide rails, spindle units, chucks, positioning blocks, and servo feed systems to ensure precise alignment and connection of the wheel during machining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If two independent pieces of equipment are used for first-stage and second-stage turning, then each stage can be processed separately, but the matching precision of central hole and mandrel is low and coaxiality is deviated
Solution Approach 1:
The patent combines two independent turning equipment into one integrated machine tool, allowing the wheel to remain clamped on the same chuck throughout both first-stage and second-stage turning. This merging eliminates the need for unclamping and reclamping operations, ensuring that the central hole processed in the first stage aligns precisely with the mandrel in the second stage, thereby achieving high matching precision and coaxiality.
2Manufacturing precision
If manipulator or operators perform feeding and discharging for switching between stages, then the processing can be completed, but the coaxiality of inner side and outer side is deviated
Solution Approach 1:
By integrating both turning stages into one machine, the patent eliminates the need for manual or automated manipulator intervention between stages. The wheel remains securely clamped on the chuck throughout the entire process, removing the feeding and discharging operations that previously caused coaxiality deviations.
3Manufacturing precision
If first-stage and second-stage turning are performed on separate equipment, then the processing flexibility is maintained, but the product quality is reduced due to connection errors
Solution Approach 1:
The integrated machine tool performs both first-stage and second-stage turning in one continuous operation without requiring the wheel to be removed and transferred. This eliminates connection errors that reduce product quality while simultaneously improving productivity by removing intermediate handling steps.
Solution Approach 2:
The patent enables continuous processing of the wheel through both turning stages without interruption or removal from the chuck. The useful action of machining continues uninterrupted, maintaining high product quality while improving overall processing efficiency.
