Extensometer for high-temperature uniaxial experiment

Abstract

The invention relates to an extensometer for a high-temperature uniaxial experiment. The extensometer is characterized in that an upper machine body panel and a lower machine body panel are arranged in parallel, and ceramic ejector pins are fixedly arranged at the front ends of the upper and lower machine body panels respectively; an upper connecting plate and a lower connecting plate are correspondingly and fixedly arranged at the tail parts of the upper and lower machine body panels respectively, two connecting spring pieces are vertically arranged between the upper connecting plate and thelower connecting plate, and a strain spring piece is horizontally arranged between the upper connecting plate and the lower connecting plate; the front end of the strain spring piece is connected withthe lower connecting plate through a spring supporting block, and the tail part of the strain spring piece is connected to the upper connecting plate through a U-shaped groove; side plates are fixedly arranged on the two sides of the upper connecting plate and the two sides of the lower connecting plate, and a shell is fixedly arranged at the tail parts of the upper and lower connecting plates. The extensometer is scientific and reasonable in design, compact in structural layout and capable of ensuring normal use of the extensometer under a high-temperature condition, interference of the external environment is avoided, and the accuracy of experimental data of the extensometer is ensured.

Description

technical field [0001] The invention belongs to the technical field of material performance testing, and relates to an extensometer, in particular to an extensometer used for high-temperature uniaxial experiments. Background technique [0002] An extensometer is a test instrument for measuring the linear deformation between two points of a sample or other objects. Its purpose is to measure the actual mechanical properties of materials under specific working conditions, among which high temperature is a common working condition. The thimble of ordinary extensometers cannot withstand higher temperatures, and at the same time, the measuring elements of extensometers are easily affected by temperature in high temperature environments, resulting in large errors. [0003] Therefore, it is desirable to have a technical solution to accurately and effectively measure the length deformation of the measured object in the axial direction in a high temperature environment.
