Technical Field

The invention relates to a weapon adjusting device, in particular to an optical sighting telescope division correcting mechanism for eliminating axial movement clearance.

Background

Optical sights are devices that impart accurate sighting angles to weapons, allowing average trajectories to pass through the target, and are an important component of weapon systems.

The weapon needs to check the consistency of the firing line of the weapon and the aiming line optical axis of the optical sighting telescope before fighting or shooting, for example: the aiming optical axis of the optical sighting telescope is not parallel to the firing line or intersects with a point at a certain distance, so that the weapon system needs to be adjusted.

So that the aiming optical axis of the optical sighting telescope is parallel to or meets the firing line of the weapon at a point at a certain distance. A common method of correction is to move a reticle in an optical sighting telescope so that the center of the reticle coincides with a corresponding point placed at a distance from the calibration target.

In a common moving and dividing mechanism, a dividing lens mounting plate is arranged between a cover plate and a dividing mounting seat, and a certain gap is required to be reserved among the dividing lens mounting plate, the dividing mounting seat and the cover plate in order to ensure that the dividing lens mounting plate does not block within a large temperature range while moving. However, the control of the gap size needs to be searched and summarized through long-time tests, and can be ensured by improving the machining precision of the part.

Even if the control of the size of the gap is realized, the existence of the gap can not ensure that the dividing surface of the dividing plate is always kept on the focal plane of the aiming objective lens in the using process of the optical sighting telescope. Once the reticle has its reticle surface out of the focal plane of the sighting objective, parallax is produced by the sighting telescope optical system. The generation of parallax directly affects the aiming accuracy, and the final result is that the shooting accuracy is reduced.

Therefore, the technical staff in the field needs to solve the problem of how to provide an optical sighting telescope graduation correcting mechanism for eliminating the axial movement gap, so as to ensure that the graduation surface of the optical sighting telescope graduation plate and the focal plane of the sighting objective lens are always kept coincident, and ensure the sighting accuracy and the shooting accuracy of the weapon system.
