Embodiment 1

[0017] A pressure sensor (3) is installed on the pressure head (2), and the force value display device (4) is directly connected to the pressure sensor (3), and the pressure head (2) is connected to the lifting platform (1) through the displacement of the lifting platform (1). A pressure is generated between the pressure sensor (3) to display the pressure value between the pressure head (2) and the lifting platform (1) on the force value display device (4).

Embodiment 2

[0019] A pressure sensor (3) is installed on the pressure head (2), and the force value display device (4) is directly connected to the pressure sensor (3), and a power device is installed on the lifting platform (1), and the power device includes a stepping power supply (5) and the control device (6), the stepping power supply (5) is adjusted through the control device (6), so that the lifting platform (1) is continuously displaced, and the sample is under pressure between the lifting platform (1) and the pressure head (2). The pressure value is displayed in the force value display device (4) through the pressure sensor (3).

Embodiment 3

[0021] Install the pressure sensor (3) on the lifting platform (1), connect the force value display device (4) to the pressure sensor (3), connect the power device to the lifting platform (1), and the power device includes a stepping power supply (5) and a control device (6). Adjust the stepping power supply (5) through the control device (6), so that the lifting platform (1) is continuously displaced, so that the sample generates pressure between the lifting platform (1) and the indenter (2), and the pressure value is passed through the force display device (4) DISPLAYED.

Abstract

The invention is a kind of continuously loading dimension vickers. It includes a press head which keeps contact with the sample, and an optical system which is used for measuring the dint value under a strength or examining whether there is a crack and what its size is. The invention has one characteristic: a rise and fall flat roof is fixed in response to the press head. Moreover, the invention has some advantages for its realizing continuously loading and satisfying the modern science technique development's new request for dimension vickers.

Description

Technical field: [0001] The invention provides a continuous loading Vickers hardness tester. Background technique: [0002] With the development of material science, especially the emergence of composite materials and nanomaterials, it is necessary to measure the force value when a microscopic point or fiber is broken, peeled off and deformed locally. The usual Vickers hardness tester is a weight structure, such as: 10g, 25g, 50g, 100g, 1kg... and other intermittent methods. The load is not continuous and cannot meet the above requirements. [0003] The product of the present invention is equipped with a lifting platform on the usual Vickers hardness tester to realize continuous loading and meet the above-mentioned requirements for the Vickers hardness tester. Invention content: [0004] The object of the present invention is to provide a continuous loading Vickers hardness tester, which realizes continuous loading in hardness measurement. [0005] The invention provides...
