Description

Technical Field

[0001] The utility model relates to the technical field of thermal fatigue testing machines, and more specifically to a thermal fatigue testing machine with adjustable sample clamping position. Background Art

[0002] Thermal fatigue testing machine is a kind of testing equipment used to simulate the fatigue performance of materials or products in high temperature environment. This equipment can cycle materials or products between high temperature and low temperature through heating and cooling cycles to evaluate their durability and reliability in high temperature environment.

[0003] Thermal fatigue testing machines are usually composed of heat sources, cold sources, temperature control systems, sample fixtures, etc. During the test, the sample is placed in the sample fixture, and then the heating and cooling functions of the temperature control system are controlled to cycle the sample within a certain temperature range. Usually, thermal fatigue testing machines can perform hundreds or even thousands of cycle tests to simulate the use of materials or products in a long-term high-temperature environment.

[0005] When the structure is in use, the pointer thermometer, pointer rod, matching plate, reset spring, contact switch, adjustment plate, touch rod and temperature bag are arranged, so that the hot and cold fatigue testing machine can easily remind the staff when the temperature in the heating chamber is too high or too low. During use, when the temperature is too high or too low, the pointer rod abuts against the adjustment plate, so that the touch rod abuts against the contact switch, and the alarm sounds, thereby achieving the purpose of improving practicality. However, the structure is not easy to quickly take materials when in use, and the material is not easy to adjust the position when undergoing a thermal fatigue test, resulting in it being able to adapt to only a single position, making the device inconvenient when in use.
