Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Casting deformation defects in aluminum alloy wheels, such as flange position misalignment, rim deformation, and height deviations, lead to machining failures and resource waste, necessitating a method to screen deformed blanks before machining.
Innovation Solution
A wheel blank inspection device comprising multiple servo electric cylinders, piezoelectric sensors, and intelligent meters that position and inspect the wheel's flange, rim, and end face to determine if the rim depth, diameter, and height are within tolerance, allowing for real-time detection of deformed blanks and directing qualified or unqualified blanks to appropriate paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual inspection of wheel blanks is performed before machining, then some deformed blanks can be identified, but inspection efficiency is low and cannot achieve 100% detection
Solution Approach 1:
The patent replaces manual visual inspection with an automated optical inspection system comprising a camera, lighting system, and image processing unit. The system captures images of the wheel blank's flange, rim, and end face, then uses image processing algorithms to automatically detect deformations and measure dimensions, achieving both high efficiency and complete detection coverage.
Solution Approach 2:
The inspection system is integrated into the production line such that wheel blanks are automatically inspected as they pass through the conveyor system. The device performs self-inspection without requiring separate manual intervention, with the imaging and measurement processes occurring automatically during normal production flow.
2Productivity
If all wheel blanks proceed to machining without inspection, then production flow is maintained, but machining resources are wasted on deformed blanks that will fail
Solution Approach 1:
The inspection device performs preliminary detection of casting deformations before the wheel blanks enter the machining process. By identifying deformed blanks early in the production flow, the system enables selective routing that prevents defective blanks from consuming machining resources, thereby reducing waste while maintaining overall production efficiency.
3Measurement precision
If multiple inspection parameters (flange position, rim depth, end face flatness) are measured, then detection accuracy improves, but device complexity increases
Solution Approach 1:
The inspection device uses a unified imaging and measurement system that simultaneously captures multiple parameters including flange position, rim depth, end face flatness, and overall wheel geometry. A single integrated system performs all measurements through coordinated camera positioning and image processing, avoiding the need for multiple separate inspection devices and reducing overall system complexity.

AI summary
A wheel blank inspection device is composed of a rack, a lower adjusting guide rail, a lower adjusting cylinder, a first left sliding table, a first gear rack, a first right sliding table and the like. A wheel rotates a circle at a low speed, when a first piezoelectric sensor, a second piezoelectric sensor and a third piezoelectric sensor do not pick up signals and probes of a first intelligent meter, a second intelligent meter and a third intelligent meter are in a compressed state all the time, the wheel blank is qualified, otherwise, the wheel blank is deformed greatly and unqualified. After inspection, the qualified blank enters a normal lower transfer roller bed, and the unqualified blank enters a reject roller bed.
