Embodiment Construction

[0022] The structure and detection process of the non-contact artillery bolt firing pin deviation detection system of the present invention will be described in detail below through a specific application example.

[0023] 1. The assembly relationship and function of each main component of the detection system ( image 3 )

[0024] The detection system includes an image acquisition device, a computer processing system and a correction gauge.

[0025] The image acquisition device includes a detection gauge 4, a high-resolution CCD camera 12 fixed in the detection gauge 4, an optical lens 8 and an annular light-emitting diode light source 5, which are movably installed in the bullet chamber 13, and the outer conical surface of the detection gauge 4 and the bullet chamber The inner conical surface of 13 matches.

[0026] A handle 3 is fixed on the front portion of the detection gauge 4, so that the detection gauge 4 is pulled out from the chamber 13 after the detection is compl...

Abstract

A non-contact artillery breech firing pin deviation detecting system comprises an image acquisition device and a computer processing system. The image acquisition device movably arranged in a chamber comprises a detecting gauge, a ring light-emitting diode light source, an optical lens and a CCD camera; wherein the outer conical surface of the detecting gauge is matched with the inner conical surface of the chamber; the frontal end of the detecting gauge is provided with a calibrated wafer the center of which is provided with a gauge hole; the optical lens is fixedly arranged at the back of the detecting gauge; the back of the optical lens is fixedly provided with the CCD camera; the ring light-emitting diode light source is fixedly arranged around the optical lens; and the CCD camera is connected with the computer processing system arranged at outside of the chamber through data lines. The deviation detecting system images the cocked position of the firing pin and locates firing pin center through image processing techniques, thus measuring the deviation from the firing pin to the chamber center.

Description

technical field [0001] The invention belongs to the technical field of artillery precision detection, and relates to the detection of the deviation degree of the firing pin of the artillery breech, in particular to a non-contact detection system for the deviation degree of the firing pin of the artillery breech. Background technique [0002] Artillery is an important weapon in modern weaponry, and it is also the weapon with the largest number of armed forces in the world. In the manufacture, assembly, maintenance and use of artillery, in order to ensure the reliable accuracy of artillery firing, the deviation between the center of the artillery breech and the center of the barrel of the artillery barrel is one of the items that must be inspected. [0003] The existing detection method for the deviation degree of the firing pin of the artillery breech is to realize indirect manual measurement by hitting the cartridge equipped with lead primer by the firing pin. The measureme...
