AI Technical Summary
Technical Problem
When testing media materials in a vacuum chamber, conventional methods suffer from the problem of unstable media material fixation and easy misalignment.
Method used
The system employs a linkage clamping mechanism, including a lower lifting mechanism and an upper lifting mechanism. Through the cooperation of the support frame, the lower cylinder, and the upper cylinder cover, it achieves stable clamping and release of the ceramic sheet.
Benefits of technology
This ensures the stability of the medium material in a high-temperature vacuum environment, avoids misalignment of the medium material during transportation, and improves the reliability and accuracy of the test.
