Portable multi-working-condition universal shaft calibration device

Abstract

The invention discloses a portable multi-working-condition universal axis calibration device which comprises an optical objective lens assembly (1), an optical eyepiece assembly (2), a spectroscope (3), an imaging display assembly (4), a laser assembly (5), a centering cylinder (6) and a lens cone (7). Target light is split by the spectroscope (3) and then reaches the imaging display assembly (4) and the optical eyepiece assembly (2). An indication light beam of the laser assembly (5) points to the center of a target; through function extension, the overall optical axis direction is adjusted through the added double-optical wedge lens set (8), the optical reticle provides an alignment reference target, and the multiple reflection elements are matched to achieve positive image visual observation and eliminate the aiming error caused by off-axis use of the laser assembly (5). According to the device, three axis calibration working conditions of active laser indication, electronic image and visual optics are realized at the same time, and the technical problem of quick and accurate gun calibration under complex terrains, meteorological conditions, day and night environments and special conditions is solved.

Description

technical field [0001] The invention relates to a multi-working-condition universal shaft calibrating device, in particular to a portable multi-working-condition universal shaft calibrating device. Background technique [0002] With the continuous upgrading of army weapons and equipment, higher requirements are put forward for the rapid and accurate axis calibration (referred to as school guns) of army artillery with direct-firing functions such as tank artillery, infantry fighting vehicle artillery and self-propelled artillery. Rapid gunning capability in complex terrain, weather conditions and day and night environments. [0003] The traditional and newer shaft calibration devices mainly include: optical calibration gun mirror, electronic image calibration device and laser calibration device, which are three single-condition calibration devices. Among them, the optical school gun mirror is used to visually observe the distant target to conduct the school gun. The disadvan...

Problems solved by technology

[0004] The purpose of the present invention is to provide a portable multi-working-condition general-purpose alignment device, which solves the problem that previous devices require the cooperation of multiple people, and the search for distant targets is limited by the terrain and is not suitable for night-time alignment and foggy, hazy, light rain and snow. Complicated meteorological conditions such as the sky affect visibility, insufficient adaptability to complex terrain environments where it is not convenient to set up targets, and the problem that it cannot be used under special circumstances where the laser is easy to expose our targets
