Embodiment 1

[0033] For example, to test the compressive strength of a concrete sample.

[0034] First, the MTS testing machine is used to respectively pull the clamping device for clamping the upper part and the lower part of the clamp according to the present invention to an appropriate distance. After the compression clamp according to the present invention is installed at this distance, the remaining space can be Place the sample to be tested with a margin of 2-8mm;

[0035] The upper part and the lower part of the anti-compression fixture of the present invention are respectively installed in the V-shaped groove of the wedge 0-2 of the MTS testing machine, and clamped, such as Figure 4 As shown; the specific installation process is as follows: First, insert the upper holding rod 1-1 of the upper part of the compression fixture into the V-shaped groove of the wedge 0-2 until the upper limit block 1-2 faces the upper holding rod 1 The surface of -1 is in contact with the top surface o...

Abstract

The invention discloses a compression-resisting clamping tool for testing the compression resistance of non-metallic materials, belonging to the technical field of material performance testing. The compression-resisting clamping tool comprises an upper part and a lower part; the upper part has the structure that: an upper held rod is arranged on the upper part of an upper limiting block and fixedly connected with the upper limiting block, and the upper limiting block is fixedly connected with an upper compression-bearing part, wherein the diameter of the upper limiting block is larger than that of the upper held rod; the lower part has the structure that: a lower held part is arranged on the lower part of a lower limiting block and fixedly connected with the lower limiting block, wherein the diameter of the lower limiting block is larger than that of the lower held rod; the lower limiting block is fixedly connected with a first lower compression-bearing plate; the first lower compression-bearing plate is connected with a second lower compression-bearing plate in a ball-joint way; and a lower compression-bearing surface is one of the surfaces of the second lower compression-bearing plate and provided with scales for positioning the sample. The compression-resisting clamping tool disclosed by the invention has high testing precision, the compression-bearing surfaces have high hardness, the sample can be placed and positioned accurately, and the compression process and testing of the non-metallic materials with large cross sections can be realized.

Description

technical field [0001] The invention belongs to the technical field of material performance testing, and in particular relates to a compression-resistant fixture for testing the compression-resistant performance of non-metallic materials. Background technique [0002] Mechanical Testing & Simulation MTS is a well-known manufacturer of material testing machines, especially dynamic material testing machines. MTS is the first manufacturer in the world to introduce computer automatic control technology into the field of testing machines. Years of successful experience have enabled MTS to establish an unshakable position in the field of mechanical testing. Since the 1980s, software technology has been widely used in the field of scientific research and testing, and MTS is the first manufacturer to introduce full software drivers into the field of testing machines. This measure not only reduces the number of hardware, but also improves the reliability of the whole machine. More ...
