Problems solved by technology

[0003] In the actual high-temperature mechanical test, the inventor found that the front end of the extension rod of the extensometer is prone to slipping relative to the surface of the tested test piece during the test, which will cause inaccurate, wrong or failure of the test, which will lead to Test success rate reduces efficiency and increases test cost
In addition, the existing high-temperature extensometers are difficult to install and operate.

Abstract

The invention provides an extensometer auxiliary assembly, which is used to cooperate with a contact type high-temperature extensometer to perform a high-temperature mechanical test, and includes a buckle assembly, which includes a U-shaped sleeve and a rotating block; The bottom and two sides of the shape, the bottom has an inner knife edge; the rotating block has a rotating part, a crimping part, a counterweight part and a connecting part, and the rotating block and the U-shaped sleeve define the channel of the test piece for the test section of the test piece Pass through, the inner knife edge and the end side knife edge are located on the opposite sides of the test piece passage, and the counterweight keeps the end side knife edge to rotate to narrow the test piece passage, so that the inner knife edge and the end side knife edge are respectively pressed from both sides of the test piece. Tighten the two opposing surfaces of its test section. The present invention also provides a high-temperature mechanical test device comprising the above-mentioned extensometer auxiliary assembly. The aforementioned extensometer auxiliary components can reduce the risk of extensometer slipping, improve the success rate of the test, and can also reduce the difficulty of installation and operation of the contact high-temperature extensometer.

Description

technical field [0001] The invention relates to a high temperature mechanical test device, comprising a contact type high temperature extensometer. Specifically, the present invention also relates to an extensometer auxiliary component, which can be matched with a contact high temperature extensometer to perform high temperature mechanical test. Background technique [0002] With the continuous development and updating of technology, many new high-temperature structural materials have appeared, and the design and use temperature of such high-temperature structural materials are often very high. Taking ceramic matrix composite materials as an example, this material has a wide application prospect in the aerospace field, and the test temperature for the high temperature mechanical properties of this material is often above 1200 °C. Therefore, it is often necessary to use a contact high temperature extensometer to measure the load deformation of this new high temperature struc...
