Description
Предметом изобретени вл етс способ автоколлимационного измерени малых перемещений при испытании анероидных коробок, авиационных высотомеров в разреженной воздушной среде.The subject of the invention is a method for autocollimation measurement of small displacements when testing aneroid boxes, aircraft altimeters in a rarefied air environment.
Этот способ отличаетс от примен ющегос способа измерени катетометром тем, что кроме измерени линейных перемещений шпил анероидной коробки производитс измерение угловых ее перемещений.This method differs from the method used for measuring with a cathetometer in that, in addition to measuring the linear displacements of the aneroid box spiers, it measures its angular displacements.
Предлагаемый способ заключаетс в том, что на щпиле анероидной коробки закрепл ют зеркало, при помощи которого получают автоколлимационные изображени сетки объектива микроскопа относительно сетки окул ра. Величины смещени сетки определ ют линейные и угловые смещени щпил анероидной коробки. Применение такого способа повыщает качество проверки анероидных коробок.The proposed method consists in fixing a mirror on the pin of the aneroid box, with which the autocollimation images of the grid of the objective lens of the microscope are obtained relative to the grid of the ocular. The magnitude of the displacement of the grid determines the linear and angular displacements of the aneroid box chips. The use of this method improves the quality of checking aneroid boxes.
На фиг. 1 показана схема проверки анероидной коробки; на фиг. 2-автоколлцмационные изображени от зеркала в двух видах а и б.FIG. 1 shows an aneroid box inspection scheme; in fig. 2-autocollimation images from a mirror in two types a and b.
Апероидна коробка 1 установлена в камере 2 и соедин етс снизу трубкой с резервуаром, подающим внутрь коробки избыточное воздущное давление. С правой стороны камера имеет трубку 3, присоедин емую к форвакуумному насосу. Над камерой установлен микроскоп с объективом 4 и винтовым окул ром-микрометром 5. На щпиле анероидной коробки установлено зеркало 6.Aperoid box 1 is installed in chamber 2 and is connected to the bottom with a reservoir supplying excessive air pressure to the inside of the box. On the right side, the chamber has a tube 3 connected to a backing pump. A microscope with a lens 4 and a screw eye is installed with a rum micrometer 5 above the camera. A mirror 6 is installed on the pinch of the aneroid box.
Дл проверки анероидной коробки сперва наход т автоколлимационное изображение сетки нитей, прикрепленной к фронтальной линзе микроскопа, от зеркала на шпиле анероидной коробки в открытой камере. Затем закрываетс верхнее стекл нное окно камеры, и так как между объективом и зеркалом вощло окно камеры, микровинтом подачи тубуса исправл етс фокусировка автоколлимационного изображеTo check the aneroid box, first find the autocollimation image of the reticle attached to the front lens of the microscope from the mirror on the aneroid box spire in the open chamber. Then, the upper glass window of the camera is closed, and since the camera window is wrinkled between the lens and the mirror, the focus of the autocollimation image is corrected by the tube feeding screw.
