Description

Technical Field

[0001] The utility model belongs to the technical field of thermocouples and relates to a thermocouple clamping tool. Background Art

[0002] At present, in laboratory mechanical testing, high-temperature tensile tests and high-temperature creep tests usually require binding three thermocouples to the surface of a specimen, which takes a lot of time and accounts for 2 / 3 of the entire specimen loading time. And the ropes for binding thermocouples are generally molybdenum wire or asbestos rope. However, asbestos rope is very easy to break brittlely, and the harmful gases generated by combustion are likely to cause irreversible damage to the respiratory tract of the tester. Metal particles such as calcium and magnesium in asbestos rope are likely to undergo penetration reaction with the metal specimen at high temperature, corrode the surface of the specimen, cause the specimen to break prematurely, and affect the reliability of experimental data. While metal wires similar to molybdenum wire have a high purchase cost and are extremely easy to oxidize and produce slag at high temperature. After the experiment, there is too much metal slag on the surface of the equipment, making it difficult to clean. Content of the Utility Model

A left fixed ball is arranged at the left end of the clamping rod, and a right fixed ball is arranged at the right end of the clamping rod.

[0009] Further, a plurality of quick insertion holes are provided on the thermocouple quick insertion assembly. A guiding ramp is provided inside each quick insertion hole, and a vertical hollow channel is provided on the guiding ramp.

The sizes of the left semi-circular clamp 4 and the right semi-circular clamp 5 are slightly larger than the size of the specimen 1.

Open holes are made on the back of the semi-circular clamp and are connected by a connecting pin 14. The left semi-circular clamp 4 and the right semi-circular clamp 5 can rotate along the connecting pin and can be opened and closed at will.
