Solution Overview
Problem
Current methods for detecting the concavity of a wheel's flange face in automatic production are not 100% effective, as they rely on manual spot checks or three-coordinate systems, which are insufficient for continuous and precise detection.
Innovation Solution
A device comprising a frame, jacking cylinder, guide posts, detection bars, and piezoelectric sensors that position and clamp the wheel to detect the concavity of the flange face by analyzing the timing of signal reception from sensors on detection bars, allowing for high-precision and automated 100% detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual spot check with artificial knife straight edge or three coordinates is used, then device complexity is reduced, but measurement precision and detection completeness deteriorate
Solution Approach 1:
The detection device segments the flange face into multiple detection zones using multiple detection bars arranged at different positions and angles. Each detection bar independently measures a specific region, collectively achieving complete coverage of the entire flange face surface for precise concavity detection.
Solution Approach 2:
The patent replaces manual mechanical inspection methods (artificial knife straight edge) with an automated detection system using detection bars and sensors. This substitution eliminates human subjectivity and achieves consistent, precise measurements while maintaining operational simplicity.
2Ease of operation
If manual spot check method is used, then ease of operation is improved, but productivity and detection completeness deteriorate
Solution Approach 1:
The detection device is designed to automatically position and measure the flange face without requiring manual intervention. The system self-adjusts through the coordinated movement of multiple detection bars and sensors, achieving both operational simplicity and high productivity simultaneously.
Solution Approach 2:
The patent implements continuous detection capability where multiple detection bars simultaneously measure different regions of the flange face in one operation. This eliminates the sequential spot-checking process, enabling 100% detection coverage while maintaining ease of operation through automated continuous measurement.
3Measurement precision
If automated detection system with multiple detection bars and sensors is implemented, then measurement precision and productivity are improved, but device complexity increases
Solution Approach 1:
The detection bars are designed with multi-functionality, serving both as positioning elements and measurement elements. Each detection bar can detect concavity at multiple locations and angles, reducing the total number of components needed while maintaining high measurement precision across the entire flange face.
Solution Approach 2:
The detection system employs a nested arrangement where detection bars are positioned within the wheel structure, and sensors are mounted on the detection bars. This nested configuration maximizes measurement capability within a compact framework, reducing overall device complexity while maintaining precision.
4Productivity
If 100% detection in automatic continuous production is achieved, then productivity and reliability are improved, but device complexity and investment cost increase
Solution Approach 1:
The detection device performs preliminary positioning and alignment of the wheel before the actual concavity measurement. The detection bars are pre-positioned according to the flange face geometry, enabling immediate 100% detection upon wheel insertion without requiring complex real-time adjustment mechanisms during production.
