Description

Известны способы контрол  точности обработки несферических поверхностей с применением автоколлимационной установки. Однако такие способы не обеспечивают возможность контрол  качества несферических поверхностей.Known methods of controlling the accuracy of processing non-spherical surfaces with the use of autocollimation installation. However, such methods do not provide the ability to control the quality of non-spherical surfaces.

В описываемом способе дл  определени  характера и величины отклонени  формы контролируемой поверхности измер ют разности сагиттальных и меридиональных фокусных рассто ний отдельных элементов поверхности дл  сравнени  их с расчетными данными.In the described method, the differences in the sagittal and meridional focal lengths of individual surface elements are measured to determine the nature and magnitude of the deviation of the shape of the test surface for comparing them with the calculated data.

На чертеже изображена схема установки дл  осуществлени  предлагаемого способа.The drawing shows an installation diagram for carrying out the proposed method.

Способ контрол  точности обработки несферических поверхностей состоит в том, что пучок лучей от источника 7 света направл ют через конденсатор 2 и отверстие 3 в зеркале 4, служащее диафрагмой , в объектив 5, задний фокус которого совпадает с отверстием 3. Параллельный пучок лучей направл ют с помощью зеркала 6 на контролируемый элемент 7 несферической поверхности 8, а отраженные пучки собираютс  в главных меридиональном и сагиттальном фокусах элемента 7. Затем перемещают микроскоп 9 вдоль оси 10 рращен«  поверхности 8 до тех пор, пока передний фокус // объектива 5 последовательно не совместитс  с сагиттальным и меридиональным фокусами элемента 7. Тогда отраженный от элемента 7 пучок срета проходит через объектив 5, отражаетс  от зеркал 4 ц 12 и собираетс  в фокусе 13 объектива М, где его наблюдают с помощью окул ра 15.The method of controlling the accuracy of processing non-spherical surfaces is that the beam of rays from the light source 7 is directed through the capacitor 2 and the hole 3 in the mirror 4, which serves as the diaphragm, to the objective 5, the back focus of which coincides with the hole 3. The parallel beam of rays is directed using the mirror 6 on the monitored element 7 of the non-spherical surface 8, and the reflected beams are collected in the main meridional and sagittal foci of the element 7. Then the microscope 9 is moved along the axis 10, the surface 8 is rotated until the front the focus // of the lens 5 is not consistently aligned with the sagittal and meridional foci of element 7. Then, the beam reflected from element 7 passes through the lens 5, is reflected from mirrors 4 q 12 and is collected at the focus 13 of lens M, where it is observed with the ocular 15 .

Разность сагиттального и меридионального фокусных рассто ний определ ют при помощи щкалы, на которой отмечают положение микроскопа 9 при совпадении фокуса 11 объектива 5 с фокусами элемента 7. Перемещением зеркала 6 вдоль оси 10 и поворотом его относительна оси 16, перпендикул рной оси 10, направл ют пучки света на другие участки поверхности 8, производ т определени  фокусных рассто ний дл  этих участков, после чего стро т графики, сопоставл ют iqiHThe difference between the sagittal and meridional focal lengths is determined using the slides, on which the position of the microscope 9 is noted when the focus 11 of objective 5 coincides with the focus of element 7. Moving the mirror 6 along axis 10 and rotating it relative to axis 16, perpendicular to axis 10, direct light beams on other parts of the surface 8, determine the focal lengths for these areas, after which graphs are drawn, iiHi are compared
