Abstract

The invention relates to a sample clamping device for shear force measurement at low temperature. The device comprises a pressure applying unit, an upper flange, a first pressing block, a second pressing block, a third pressing block, a lower flange, a first guide rod and a second guide rod, wherein the pressure applying unit is fitted with the upper surface of the upper flange and used for applying pressure to the upper flange; the upper surface of the first pressing block is connected with the lower surface of the upper flange; the lower surface of the first pressing block is an inclined plane and a first groove is formed in the lower surface of the first pressing block; the lower surface of the third pressing block is connected with the upper surface of the lower flange; the upper surface of the third pressing block is an inclined plane and a second groove is formed in the upper surface of the third pressing block; the upper surface of the second pressing block is matched with the lower surface of the first pressing block and a third groove opposite to the first groove is formed in the upper surface of the second pressing block; the lower surface of the second pressing block is matched with the upper surface of the third pressing block and a fourth groove opposite to the second groove is formed in the lower surface of the second pressing block. The sample clamping device can measure maximum shear force among different materials at the low temperature.

Description

technical field [0001] The invention relates to the field of low temperature measurement, in particular to a sample clamping device for low temperature measurement of shear force. Background technique [0002] With the development of my country's hydrogen energy, nuclear fusion energy, aerospace, applied superconductivity, gas industry and some large scientific projects, in terms of industry and scientific research, projects involving low temperature engineering are increasing, and the demand for low temperature materials is increasing The requirements for performance data of cryogenic materials are increasing day by day. Materials work in a low temperature environment, and their low temperature physical properties are usually different from those at room temperature. Among them, the mechanical properties of materials are an important performance index of engineering application materials or workpieces. Testing the mechanical properties of materials at low temperatures is o...
