AI Technical Summary

⚠Technical Problem

Existing tensile testing devices require different types of chucks to be replaced depending on the workpiece material, resulting in low testing efficiency and difficulty in guaranteeing accuracy, especially since it is difficult to accurately control the friction force by manually adjusting it.

⚗Method used

An optical path group is formed by an optical emitter and an optical receiver. The workpiece thickness deformation value is calculated by the optical path difference. The friction between the clamping assembly and the workpiece is automatically adjusted to ensure that the tensile measurement is performed under the preset friction force.

🎯Benefits of technology

It improves the accuracy and efficiency of tensile testing, is suitable for various types of workpieces, requires no change of chuck, and the clamping components are automatically adjusted, reducing manual intervention.

Abstract

The present application provides a kind of tensile measurement method and tensile measurement device, tensile measurement method includes: by first clamping component clamping the end point of gauge section, by second clamping component clamping the other end point of gauge section;By light emitter towards the light of workpiece before stretching is emitted to light receiver and forms first optical path group and sends to processor returning to workpiece;Workpiece is stretched in longitudinal direction;By light emitter towards the light of workpiece in stretching process is emitted to light receiver and forms second optical path group and sends to processor returning to workpiece;By processor obtains thickness deformation value and sends to controller;By controller control first clamping component and second clamping component corresponding distance are moved towards workpiece.The corresponding distance of first clamping component and second clamping component is moved towards workpiece and equal to thickness deformation value, so that the size of friction between first clamping component and second clamping component and workpiece respectively always remains at the size of preset friction.
