High/low temperature complex atmosphere environment loading device

Abstract

The invention relates to a high / low temperature complex atmosphere environment loading device, which belongs to the field of high and low temperature mechanical performance testing of materials. Including vacuum / inert atmosphere environment construction unit, high temperature environment construction unit and low temperature environment construction unit, the vacuum / inert atmosphere environment construction unit is rigidly connected to the external installation platform through the base, and cooperates with the external guide rail through the rollers to realize that the whole device moves along the direction of the guide rail. Free movement; the high-temperature environment building unit is connected to the front and rear fixed components through connecting rods; the low-temperature environment building unit is connected to the front and rear fixed components through refrigerant pipes I~IV. The advantages are: it can flexibly integrate various high-resolution in-situ imaging equipment to realize in-situ monitoring of the macro-microscopic surface morphology of the tested material sample; it can integrate one or more mechanical loading devices to realize the test of the tested material. Loading of single and compound loads; vacuum / inert atmosphere components can be integrated to realize the construction of vacuum / inert atmosphere environment.

Description
