Radial Force Roller Assembly for Stable Contour Measurement Under Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Contour measuring devices face challenges in applying radial forces to workpieces without causing deformation or displacement, especially when measuring loaded cylindrical or wave-shaped objects, as existing solutions do not effectively manage the distribution of forces to prevent lateral movement and ensure stability during measurement.
Innovation Solution
A radial force device with a clamping body, force introduction roller, counter rollers, and a coupling device that allows for radial gripping and force application, providing stability and degrees of freedom to prevent lateral forces, featuring a U-shaped clamping body with counter rollers aligned to support the workpiece and a movement reversal device for controlled force application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a radial force is applied to the workpiece during measurement, then operational load simulation and material resistance testing are enabled, but workpiece displacement and measurement instability occur
Solution Approach 1:
The force introduction roller acts as an intermediary element between the clamping body and the workpiece. It applies radial force to the workpiece while being supported by the clamping body, preventing direct force application that would cause displacement. The roller mediates the force transmission in a controlled manner that maintains measurement stability.
Solution Approach 2:
The counter-roller provides a counterbalancing support force to the workpiece when the force introduction roller applies radial load. This counter-support prevents the workpiece from being pushed out of position between the centering points, maintaining stability during loaded measurement.
2Ease of operation
If the force introduction roller is mounted radially displaceable on the clamping body, then controlled force application is achieved, but lateral forces may cause workpiece displacement
Solution Approach 1:
The counter-roller serves as a mediator that counteracts lateral forces generated by the radially displaceable force introduction roller. When the force roller applies radial force, the counter-roller provides opposing support to prevent the workpiece from displacing laterally, enabling controlled force application without compromising position stability.
3Stability of the object's composition
If counter rollers are added to support the workpiece during force application, then workpiece stability is improved, but device complexity increases
Solution Approach 1:
The clamping body serves multiple functions: it provides structural support for the force introduction roller, houses the counter-roller, and couples the radial force device to the contour measuring device. By making the clamping body multi-functional, the patent avoids adding separate components for each function, thereby reducing overall device complexity while maintaining workpiece stability.
