Since the first threaded rod 21 is threadedly connected to the translation plate 812, the rotation of the first threaded rod 21 drives the translation plate 812 to move, and the translation plate 812 drives the viscosity meter 11 to move left and right, so that the position of the viscosity meter 11 can be further adjusted, so that the viscosity meter 11 and the rotor 13 can be in a better position to measure the high-temperature liquid fluid. When testing a high-temperature liquid fluid, the viscosity meter 11 can be moved left and right to change the testing position, so that the viscosity of the high-temperature liquid fluid can be judged according to the test data of multiple positions, so that the data of the device for testing the viscosity of the high-temperature liquid fluid is more accurate, and a pair of small baffles 29 and a pair of large baffles 30 are fixedly connected to the top of the outer wall of the placement plate 26, and the pair of small baffles 29 and the pair of large baffles 30 form a placement space, so that when placing the viscosity meter 11, the viscosity meter 11 can be directly placed on the placement plate 26 from above the large baffles 30 and the small baffles 29, and when taking it, the viscosity meter 11 can be directly moved upward to take it, so that the taking and placing of the viscosity meter 11 is not only convenient, but also simple to operate, The device makes it more convenient to repair or replace the viscosity meter 11, and the fourth motor 23 drives the second threaded rod 24 to rotate. Since the second threaded rod 24 is threadedly connected to the connecting block 25, the second threaded rod 24 drives the connecting block 25 to move, and the connecting block 25 drives the placement plate 26 to move, thereby driving the viscosity meter 11 to move, so that the fourth motor 23 cooperates with the rotation of the third motor 20, so that the viscosity meter 11 can not only move left and right, but also move forward and backward, thereby increasing the moving range of the viscosity meter 11, so that the viscosity meter 11 can adjust the position more accurately, so that not only the rotor 13 on the viscosity meter 11 can fall into the crucible 10 more accurately, but also through the left and right plus front and back movements of the viscosity meter 11 The viscometer 11 can detect viscosity data at more positions, so that the control computer 16 can obtain more data to judge the viscosity of the high-temperature liquid fluid, so that the accuracy of the data is further improved when the device detects the high-temperature liquid fluid, and when the crucible 10 is placed in the corundum tube 4, a pair of shockproof plates 31 will clamp the corundum tube 4, so that when the high-temperature liquid fluid in the crucible 10 is detected, the pair of shockproof plates 31 can play a shock-absorbing role, making the crucible 10 more stable, so that the device not only reduces external interference, but also reduces the probability of movement or shaking of the crucible 10 when the rotor 13 rotates or moves, so that the data detected by the device is not only stable and accurate, but also when the viscosity meter 11 is tested,The viscometer tests a data every 3-5 seconds and transmits the data to the control computer 16. At the same time, the temperature control thermocouple 14 and the temperature measuring thermocouple 15 also transmit the temperature data to the control computer 16 every 3-5 seconds. The average value of every 3-10 data is taken as the recorded data to make the measurement data more accurate. The high-temperature furnace 2 can heat up or cool down, so that the viscosity meter 11 can detect the test sample at room temperature, constant temperature, and different high temperatures. After the test is completed, the high-temperature furnace 2 is cooled at a certain cooling rate. When the temperature drops to the specified temperature, such as 500°C, the protective gas is stopped, and the water cooling is stopped. Finally, the control computer 16 automatically organizes the collected temperature and viscosity data lists, and draws the temperature-viscosity curve to complete the data collection and sorting.
