Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] Such as Figure 1-Figure 3 As shown, the multifunctional uniaxial tensile test device for in-situ on-line observation of microstructure can realize in-situ tension when the sample is energized, the sample is not energized, the sample is placed horizontally and loaded, and the sample is placed sideways. The test consists of four parts: frame, power transmission, clamping and force measurement.

[0032] The frame is composed of base plate 1, motor holder 2, guide rail 19, 19-1;

[0033] Wherein, the motor fixing seat 2 is installed on the bottom plate 1, the guide rails 19 and 19-1 are parallel to the axis of the motor 3, and the guide rails 19 and 19-1 are symmetrically arranged in guide rail grooves on both sides of the axis of the motor 3.

[0034] The power transmission part includes a motor 3, a shaft coupling 4, a screw 8, a screw ...

Abstract

The invention relates to a multifunctional uniaxial tensile test device for microstructure in-situ online observation. The device comprises a rack, a power transmission mechanism, a clamping mechanism and a force measurement mechanism, wherein the clamping mechanism comprises three detachable fixing bases corresponding to a pair of sliding tables and fixation bases, three pins and three insulating washers; the detachable fixing bases are in an inverted-T shape, can be mounted on top surfaces or side surfaces of the sliding tables/ the fixation bases through concave holes in the sliding tables and the fixation bases and are fixed through the pins; an upper clamping block and a lower clamping block used for clamping a test sample are fixed on the first two detachable fixing bases; the three insulating washers separate the three detachable fixing bases from the corresponding sliding tables or the fixation bases; the clamping mechanism and the force measurement mechanism are mounted at the upper parts of the sliding tables and the fixation base at the right end of a screw. The test sample keeps balanced, and microstructure in-situ observation is performed in the horizontal plane of the test sample in the tensile process; the clamping mechanism and the force measurement mechanism are mounted on side surfaces of the sliding tables and the fixation base at the right end of the screw, the test sample stands on one side, and the microstructure in-situ observation in a side plane of the test sample can be realized in the tensile process.

Description

technical field [0001] The invention relates to a multifunctional uniaxial tensile test device for in-situ on-line observation of microstructures, belonging to the technical field of metal tensile test devices. Background technique [0002] With the continuous improvement of the level of industrial automation, the requirements for product performance continue to increase, such as high strength, large elongation, etc. The macroscopic comprehensive mechanical properties of materials are always determined by their microstructure properties. In order to improve the macroscopic mechanical properties and development performance of materials For better new materials, research on the microstructure of materials is an effective way, and the premise of conducting research is to obtain experimental data on the microstructure of materials under different experimental conditions, and the current traditional testing machine is not suitable for observation of the microstructure of materials...
