Description

A vehicle-mounted cannon howitzer sight detection seat

technical field

The utility model relates to the technical field of sight detection, in particular to a vehicle-mounted cannon howitzer sight detection seat.

Background technique

Checking the zero line of the gun is an important content before the gun is fired. Its purpose is to ensure that the gun is in the correct starting reference in height and orientation, because it is directly related to the firing accuracy of the gun. At the same time, accurate measurement of the line of sight offset is also an important factor to ensure the accuracy of artillery design. The artillery aiming system of the existing vehicle-mounted cannon howitzer is not provided with a vertical and horizontal inspection seat, so it is impossible to detect whether the sighting device maintains an accurate vertical and horizontal level.

As shown in Figure 4, the aiming system consists of a sighting frame, a sight, and a sighting scope. The sight frame is mainly composed of a sight holder, a pull rod, etc. The sight frame is used to install the sight, and the sight and the cradle are pitched synchronously through the parallel four-bar linkage mechanism. The cradle is connected, and the sighting tool seat, the tie rod, the cradle and the upper frame form a parallel four-bar linkage mechanism. As shown in Figure 5, the sight is composed of a support arm, a shooting angle setting mechanism, a digital display device, a mirror base, a tilt adjuster, a vertical and horizontal level, and a lighting device. Angle, and the tilt angle is compensated when the gun is tilted, and the sight is installed on the sight seat of the sight frame. The sight is used to set the directional shooting angle and take into account the direct aiming. The sight is mainly composed of a direction mechanism and an optical system. After the parallel light beam injected by the target enters the objective lens through the right-angle reflecting prism, it is imaged on the reticle plane, and then is imaged on the focal plane of the eyepiece through the relay lens I, Dove prism, pentaprism and relay lens II. The eyepiece is enlarged, and the human eye can see the reticle and the target image on the reticle at the same time through the eyepiece.

The errors caused by the sighting system are mainly due to the non-perpendicular axis of the trunnion and the gun body, the non-parallel between the tilting swing axis of the sight and the barrel axis, the deformation of the sight support arm, the skew of the sight and the sight base, and the incorrect installation of the inclined level bubble. Next, we focus on the analysis that the tilting and swinging axis of the sight is not perpendicular to the rotating axis of the sight. The quadrant of the distribution equipment does not match the quadrant of the sight, which makes it impossible to accurately detect whether the sight is vertical or not. There is no horizontal inspection seat, which makes it impossible to accurately detect whether the sight is horizontally horizontal, which may lead to the following problems:

(1) After the level bubble is installed disorderly or the level bubble is damaged, it is impossible to determine whether the level bubble is centered, resulting in an error in the aiming line system;

(2) If the sight or sight arm is deformed, it cannot be detected whether it is deformed;

(3) The sight and the sight frame are produced by two different manufacturers. Before the sight leaves the factory, the level bubble is installed by the sight manufacturer, and the later maintenance and debugging are not considered.
