Embodiment Construction

[0022] The detailed content of the present invention and its specific implementation will be further described below in conjunction with the accompanying drawings.

[0023] see Figure 1 to Figure 7 As shown, the fixture of the present invention used for in-situ testing of the microscopic properties of functional materials is composed of two pairs of fixtures with the same structure, wherein the fixture I with steps is connected to the shaft coupling through bolts and pins, and the fixture I The difference is that the clamp body II13 of the clamp II has no steps, and the clamp II without the steps is connected with the tension and torque sensor through the countersunk bolts to realize the dynamic real-time measurement of tension / pressure and torque; the structures of the clamps I and II are: The clamp body Ⅰ1 and the tightening sleeve 2 are connected by threads, and one end of the tightening sleeve 2 goes deep into the grooves of the compression wedges Ⅰ, Ⅱ7, 8. When the tight...

Abstract

The invention relates to a fixture for specimen samples in in-situ testing of microscopic properties of functional materials, and belongs to the technical field of material microscopic performance testing and the technical field of optomechanical integration. Its structure includes parts such as clamp body, tightening sleeve, bushing, pin, compression wedge and clamping wedge. The tightening sleeve is connected with the clamp body and the compression wedge. The inner surface of the bushing is connected, and the bushing is connected with the clamping wedge through the compression wedge. The advantage is that it can not only realize the clamping of specimen samples in single-load loading tests such as tension, compression, and torsion, but also realize composite load loading tests such as tension-torsion, compression-torsion, tension / compression-torsion, and corresponding fatigue The clamping of the specimen sample in the loading test can also be compatible with thermal, electric, magnetic and other physical field loading units, so as to realize the loading and testing of the compound working conditions of the tested specimen sample with multiple physical fields and multiple load modes. Compact structure, convenient operation and high compatibility.

Description

technical field [0001] The invention relates to the technical field of material microscopic performance testing and the technical field of optical-mechanical-electrical integration, in particular to a fixture for specimen samples in in-situ testing of functional material microscopic performance. It can realize the clamping of specimen samples in the tensile / compression-torsion composite load test of functional materials, especially the pull-down / compression-torsion-bending multi-load material test pilot test in thermal, electrical, magnetic and other multi-physical field loading environments clamping of samples. Background technique [0002] In the last century, material testing machines were mainly aimed at structural materials. With the development of science and technology and economy, the large-scale application of new materials—especially ferro-electric, ferro-magnetic, thermal-magnetic and semiconductor materials, etc. The necessity of research on mechanical propertie...
