Description

technical field [0001] The invention relates to the field of measuring the rifling of a rifled gun, in particular to a non-contact rotary scanning device for the inner surface of a gun bore. Background technique [0002] As an important factor affecting the performance of artillery, rifling is an indicator that needs to be focused on during inspection. Most of the detection of small-caliber artillery bores adopts contact detection methods. Contact detection causes large detection errors due to wear and tear of detection tools and human factors. It cannot meet the detection requirements of fast and accurate gun bore. Therefore, driven by many factors such as the development of related technologies and the increasing demand for artillery applications, photoelectric sensing technology has gradually become the main way to complete detection. However, the measurement device using photoelectric sensing technology generally needs to build a linear and rotary motion actuator outsid...

AI Technical Summary

Problems solved by technology

However, the measurement device using photoelectric sensing technology generally needs to build a linear and rotary motion actuator outside the gun bore, which cannot realize the positioning inside the gun bore. Therefore, the accuracy of the device installation is extremely high, and the measuring device is easily interfered by external factors. The measurement devices of laser light triangulation detection technology and semiconductor laser collimation technology can only be limited to the measurement of local taper, circular runout, roundness, radius of gun bore and wrapping angle of the gun bore, and can only measure a single parameter each time
