Description

The invention relates to means for controlling sights for measuring parallax in telescopic devices, in which the convergence of the beams of rays emanating from the image of the object and the central sign of the grid behind the eyepiece of the device under test is measured with a diopter tube using a collimator having a lens easily moving along the optical axis with a focal length of about 100 mm and the corresponding diopter scale with division through 0.1 diopters.

The eyepiece of the tube has a grid, and its lenses move along the optical axis. This allows you to correct the ametropia of the observer’s eye with an eyepiece of the diopter tube before measuring the parallax in the device.

There is a method of controlling the optical axes of the crosshairs of the diopter tube grid and the sighting mark (see N.T. Elnikov, A.F. Ditev, I.N. Yrusov "Assembly and adjustment of optical-mechanical devices" p.175-176. M. : Engineering 1974), in which to ensure measurements in front of the tested sight, a collimator with a dashed world is installed, and a diopter tube mounted on a stable tripod behind the sight eyepiece, ensuring the optical axis of the crosshairs of the diopter tube is aligned with the sighting mark of the sight, and collimator regul irovochnymi and fasteners height and horizon, with diopter lens tube is mounted on a sharp vision diopter mesh tube of eye of the beholder, get a sharp image of the broken worlds collimator and remove the countdown in diopters along the longitudinal scale diopter tube. Then, by moving the lens a second time, the diopter tube is pointed at a sharp image of the crosshair of the reticle and the sighting mark of the sight, and the count is again taken from the longitudinal scale of the diopter tube, and the difference in two samples determines the parallax value in the diopters, measured from the eyepiece of the tested sight.

This method (see N.T. Elnikov, A.F. Ditaev, I.N. Yrusov "Assembly and adjustment of optical-mechanical devices" p.175-176. M .: Mechanical Engineering 1974) we have chosen as a prototype .

The disadvantages of the prototype are:

1. The complexity of combining the optical axes of the crosshairs of the diopter tube reticle and the sighting mark of the sight due to movement and mounting of the diopter tube in height and horizon, which requires movement of both the sight and the diopter tube.

2. It requires considerable preparatory time, does not provide the highest accuracy of combining the optical axes of the diopter tube grid, the sighting mark of the sight and the dashed line of the collimator due to shifts in the height and horizon of the diopter tube.

The objective of the invention is to develop a method for controlling an optical sight with combining the optical axes of the crosshairs of the diopter tube reticle and the aiming mark of the sight with the aim of reducing labor intensity, preparation time and achieving the highest accuracy of combining the optical axes of the crosshairs of the diopter tube with simplification of the device of its fastening and aiming mark of the sight.

This object is achieved in that in the method of controlling an optical sight, according to which a diopter tube is installed in front of the sight of the sight channel of the sight, the optical axis of the crosshairs of the diopter tube and the sight mark are aligned in height and horizon with fastening and adjusting elements, in it on the sight eyepiece body a perforated bushing with adjusting elements and a separable spherical bearing inside, in which the second perforated sleeve is led into the body of the eyepiece of the sighting channel until it stops, in the cavity of which a diopter tube is fixed, after which the optical axes of the crosshairs of the diopter tube grid are aligned with the sighting mark of the sight in height and horizon by the adjusting elements.

The proposed method for controlling the optical sight is implemented by a device made in the form of a nozzle of two perforated outer and inner bushings, with a crescent-shaped clamp with loop fasteners for coaxial fixing to the barrel of the sight sight channel and adjusting in height and horizon at the front end of the outer bush elements, and inside the outer sleeve there is a separable spherical bearing in which the inner sleeve with a diopter tube is installed through an adjustable angular in height and horizon by elements, the front end of the inner sleeve and the ends of the height and horizon adjusting elements made of spherical elements on the opposite end, and inside the outer sleeve there is a separable spherical bearing in which the inner sleeve with the diopter tube is installed through the height and horizontal adjustment elements, with the front end of the inner sleeve and the ends of the elements adjusting in height and horizon are made spherical.

The invention is illustrated by graphic materials. Figure 1 shows the device for controlling the optical axes of the crosshairs of the diopter tube and sighting mark made in the form of a nozzle from two perforated bushings, figure 2 shows the attachment of the nozzle to the eyepiece of the sighting channel of the sight using a half clamp and fasteners, and Fig. .3 presents the combination of the optical axes of the crosshairs of the diopter tube reticle and the sighting mark of the sight, where
