AI Technical Summary

Technical Problem

Existing technologies make it difficult to perform high-precision, universal bore wear detection on artillery barrels of different calibers, and the measuring device cannot adapt to barrels of different calibers, resulting in detection difficulties.

Method used

An in-bore scanning device was designed. Through adaptive centering adjustment and synchronous adjustment of the laser sensor's distance from the inner wall of the barrel, it can measure the wear at different depths. The device includes a main shaft assembly, a support tube frame, a grating scale, a centering mechanism, a laser sensor, a support unit and a drive assembly, which can achieve stable support and precise scanning of barrels of different calibers.

Benefits of technology

It achieves high-precision scanning of the inner bore of artillery barrels of different calibers, improves detection accuracy and adaptability, can accurately measure wear and tear, and extend the life of the artillery.
