Abstract

The invention discloses a high-temperature strain control device, which comprises a rocker arm type extensometer, a force transducer, a pressure regulating module, a high-temperature furnace, a clamp and a machine frame, wherein the high-temperature furnace and the extensometer are fixed on a support frame of the machine frame; the clamp is used for fixing a test specimen; the force transducer is fixedly arranged at the end part of an extension rod of the extensometer, and is used for detecting the contact pressure of the extension rod and the test specimen; the pressure regulating module is fixedly arranged on the support frame of the extensometer, and is used for regulating the contact pressure of the extension rod and the test specimen to the preset pressure range according to the contact pressure detected by the force transducer. By using the technical scheme, the high-temperature strain control device has the advantages that the installation efficiency and the installation success ratio of the extensometer are improved; the damage to the surface of the test specimen and the extension rod of the extensometer can be avoided.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a high-temperature strain control device. Background technique [0002] The core of the existing high-temperature strain control system is the high-temperature extensometer, which is used to measure the small deformation of the sample, which requires high sensitivity and accuracy. Existing high-temperature extensometers cannot detect the force of the extension rod, and can only rely on the operator's hand feeling experience and long-term exploration to adjust the contact tightness between the extension rod and the sample. If the installation is too loose, the extensometer will easily slip, and if the installation is too tight It is easy to make the extension rod too tight to break and damage the sample, resulting in cumbersome installation of the high temperature extensometer and low installation success rate and installation efficiency. At the same time, the existing high-tem...
