AI Technical Summary
In the existing technology, it is difficult to fix the slow-stretching round bar specimen, and it is difficult for a single person to keep the specimen stable. Moreover, the measurement process requires the assistance of others, resulting in low work efficiency and poor measurement accuracy.
The system employs a worktable and a pneumatic fixing device, utilizes a V-groove to achieve axis centering, and uses an infrared rangefinder and a digital display screen for rapid and accurate measurement. The combination of the pneumatic fixing device and the infrared rangefinder enables rapid fixation and measurement of the sample.
It enables rapid and accurate fixation and measurement of round bar samples, improves work efficiency, reduces human error, and makes operation simpler.
