Embodiment Construction
[0040] The invention mainly designs high-temperature fatigue fixtures suitable for flat test pieces and capable of carrying out tensile tests. In fact, during the test, the whole set of fixtures includes two fixtures of the present invention, which are divided into upper fixtures and lower fixtures. The general diagram of complete installation is shown in Figure 13 .
[0041] The fixture includes the following parts: central shaft 1, left-handed nut 2, right-handed nut 3, sleeve rod 4, sleeve 5, connecting rod 6, wedge-shaped clamp body 7, guide table 8, wedge-shaped clamp block 9, countersunk head bolt 10, Block 11.
[0042] Among them, such as Figure 1-14 As shown, the static positional relationship between the various components is: the wedge-shaped clamp body 7 and the connecting rod 6 are threadedly connected, and the upper surface of the thick end of the connecting rod 6 is in contact with the lower surface of the wedge-shaped clamp body 7; The end passes through th...
