Device of detecting resiliency of the elastic of the part
Abstract: This paper is to detect resiliency of the elastic of the part ,in the mechanical, engineering and many other occasions elastic deformation parts have certain requirements, stiffness parts directly determine the performance of the system, so the elastic deformation of the elastic parts detection capability is necessary.
Image-based detection technology, through the non-contact characteristics ,It can detect of the deformation of the elastic element and processed by a computer output ,according to the structure characteristics of the precise elastic parts, the stiffness measurement principles and methods are analyzed, and the stiffness of the overall scheme of the measurement system. Design based on CCD (Charge-coupled Device) precision components elastic stiffness measurement system.
In this paper, the design includes four parts, the light source portion, CCD module parts, some parts of the clamping force loading system parts. The system features a load force is small force, but also to detect the speed of certain requirements, particularly high accuracy requirements.
Keywords: elastic parts; CCD image detection; deformation detection;
