Abstract

The invention discloses a high-temperature extension measuring device which comprises two groups of high-temperature-resistant extension rods and two sets of pushing mechanisms which are arranged on two sides of a test station, the two sets of pushing mechanisms can respectively push the two groups of high-temperature-resistant extension rods to fix a tensile sample, each group of high-temperature-resistant extension rods comprises two high-temperature-resistant extension rods, extensometers are arranged between the high-temperature-resistant extension rods and the pushing mechanisms, and heat blocking mechanisms located between the extensometers and a test station are further arranged on the peripheries of the high-temperature-resistant extension rods. The pushing mechanisms and the high-temperature-resistant extension rods are symmetrically arranged on the two sides of the test station, and the pushing mechanisms push the high-temperature-resistant extension rods to extend out to complete clamping of a tensile sample. In the test process, the deformation generated by heating the high-temperature-resistant extension rods is small, and the test error can be reduced. Meanwhile, the heat blocking mechanisms are arranged between the extensometers and the test station, heat can be effectively isolated, the influence of high temperature on the extensometers is reduced, and the test accuracy is further improved.

Description

technical field [0001] The invention relates to the technical field of high-temperature detection of materials, in particular to a high-temperature extension measurement device. Background technique [0002] Materials such as ceramics need to be tested for tensile mechanical properties in a high-temperature vacuum environment. During the test process, the detection equipment is affected by high temperature, which will cause large errors, resulting in inaccurate measurement results. [0003] Therefore, how to improve the accuracy of the tensile mechanical property test is a technical problem that those skilled in the art urgently need to solve. Contents of the invention [0004] The purpose of the present invention is to provide a high-temperature extensometer, which arranges a heat-shielding mechanism between the test station and the extensometer, and blocks the heat generated during the test through the heat-shielding mechanism to prevent the extensometer from being affe...
