Extensometer alignment adjusting device for creep fatigue testing machine

Abstract

The invention discloses an extensometer alignment adjusting device for a creep fatigue testing machine and relates to the field of test instruments. The device comprises an extensometer, an adjustingand aligning main body and an adjusting and fixing assembly. The extensometer is movably connected with the adjusting and aligning main body, the adjusting and aligning main body is arranged on the adjusting and fixing assembly, and the adjusting and aligning body comprises an alignment checking device and an adjusting base. The alignment checking device comprises an infrared transmitting device,the infrared emitting device is arranged in the adjusting base, the infrared transmitting device comprises an infrared transmitting end, the adjusting base is provided with an infrared transmitting path port in the alignment checking direction, the infrared transmitting end transmits infrared rays and the infrared rays are emitted from the infrared transmitting path port, and the adjustment and positioning of the extensometer under less human factor interference are achieved.

Description

technical field [0001] The invention relates to the field of testing instruments, in particular to an extensometer alignment adjustment device for a creep fatigue testing machine. Background technique [0002] In the industrial field, the application of engineering materials is indispensable. There are many kinds of engineering materials, and different materials have different properties, which requires us to test their properties. When different devices are in different working environments, the engineering materials used are different. Engineering materials include steel used in thermal power plant supercritical units and aero-engine materials, which are often used in high-temperature environments. At present, the testing of high-temperature performance of materials mainly includes high-temperature creep performance testing, high-temperature fatigue performance testing, and material characteristic testing under high-temperature creep and interaction. The experimental acc...
