Solution Overview

Problem

Machined aluminum alloy wheels often exhibit unqualified end surface runout due to deformation, leading to vibrations during driving and safety concerns, necessitating an automated online detection and correction system.

Innovation Solution

A wheel end surface detection and correction device comprising a stand, guide columns, servo electric cylinders, a dial indicator, and pressing blocks, which detects runout and corrects the wheel end surface by adjusting the reference plate and pressing blocks to ensure proper fitting and alignment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If automated online detection and correction equipment is introduced, then productivity and manufacturing precision are improved, but device complexity increases

Engineering Contradiction:
Improveonline detection and correction capabilityVSAvoidequipment structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The device is divided into distinct functional modules: detection system (dial indicator, translational frame), correction system (pressing blocks, servo electric cylinders), and support structure (stand, guide columns). Each module operates independently but coordinates through the control system, allowing for easier maintenance and reduced overall complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pressing blocks serve multiple functions: they apply correction force to the wheel end surface and simultaneously act as positioning elements. The servo electric cylinders provide both positioning and force application functions, reducing the need for separate components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

If the reference plate is adjusted to fit the wheel flange surface, then measurement precision is improved, but the complexity of adjustment increases

Engineering Contradiction:
Improveend surface runout detection accuracyVSAvoidreference plate adjustment mechanism
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The reference plate is designed with selective contact points on its lower surface that correspond to specific locations on the wheel flange surface. This localized contact approach ensures accurate measurement while simplifying the adjustment mechanism, as only specific points need to be precisely positioned rather than the entire surface.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The adjustment of the reference plate is achieved through servo electric cylinders that provide automated, precise positioning. This replaces manual mechanical adjustment methods, improving measurement precision while reducing the operational complexity for the user.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Force

If the expansion core tightens the wheel, then clamping force increases, but the risk of wheel deformation increases

Engineering Contradiction:
Improvewheel clamping forceVSAvoidwheel deformation
Core Design Contradiction:
ForceVSManufacturing precision

Solution Approach 1:

The expansion core is designed to apply distributed radial force against the wheel rim inner surface. By expanding uniformly in all directions, it creates a balanced clamping force that secures the wheel without creating localized stress concentrations that would cause deformation. The force is counterbalanced across the entire circumference.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

Solution Approach 2:

The expansion core allows for controlled adjustment of the clamping force through gradual expansion. The parameter of expansion diameter can be precisely controlled to achieve the optimal clamping force that secures the wheel firmly while remaining below the threshold that would cause deformation of the wheel structure.

Inventive Principle:
Principle #35Parameter changes
