Artillery barrel bore detecting system

Abstract

The invention discloses an artillery barrel bore detecting system, which structurally comprises a centering mechanism and an inner diameter measurement mechanism both mounted on a shaft lever. The centering mechanism comprises a fixed plate fixed on the shaft lever, a plurality of umbrella ribs with end parts hinged to the fixed plate and circling the fixed plate, and an elastic support mechanism mounted on the shaft lever and used for propping open the umbrella ribs. The elastic support mechanism comprises a slide block connected onto the shaft lever in a sliding manner, a spring sleeved on the shaft lever in a penetrating manner, and a stop block fixedly connected to the shaft lever, wherein the spring is positioned between the slide block and the stop block, and a support arm connected with the umbrella ribs in a sliding manner is arranged on the slide block. The detecting system is convenient to assemble, adjust, and operate, is applicable to various barrels with a diameter ranging from 100mm to 155mm, and can be used for observing image information in a tube body while detecting tube inner diameter, so that the detection results can be more reliable.

Description

technical field [0001] The invention relates to a tube inner diameter measuring instrument, in particular to a cannon barrel inner bore detection system. Background technique [0002] In an ideal state, a cylinder with the same diameter as the barrel can be used as a centering device for the inner diameter measurement of the inner bore of the tube, but there will be the following three problems: First, the gap between the cylinder and the barrel causes the centering device to be disconnected from the body. The axes of the tubes cannot coincide; the second is that with the wear of the inner wall of the barrel, the deviation between the axis of the centering device and the axis of the barrel will become larger; the third is that different centering devices must be designed for barrels of different diameters. Therefore, it is necessary to provide a centering mechanism that can adapt to the measurement of the inner bore of pipes with different inner diameters. At present, wheth...

[0002] In an ideal state, a cylinder with the same diameter as the barrel can be used as a centering device for the inner diameter measurement of the inner bore of the tube, but there will be the following three problems: First, the gap between the cylinder and the barrel causes the centering device to be disconnected from the body. The axes of the tubes cannot coincide; secondly, with the wear of the inner wall of the barrel, the deviation between the axis of the centering device and the axis of the barrel will become larger; thirdly, different centering devices must be designed for barrels of different diameters

The existing detection device can neither achieve accurate centering, nor can it find out the specific condition of the surface of the measured inner bore, so it cannot meet the needs of use
