Description

Оправа дл кретгпени сменного кругпаго оптического элемента содержит попый цилиндр 1 с наружной резьбой, диаметр меньше диаметра зарка, па, и шпицем 2 под кпюч, с помощью кото рого оправа ввинчиваетс в юстировочноё устройство (не показано).The frame for the cross-head of the replaceable circular optical element contains a backward cylinder 1 with an external thread, the diameter is smaller than the diameter of the charge, pa, and a spindle 2 under the barrel, with which the frame is screwed into the adjustment device (not shown).

На другом торне распопожены три папки 3, расход щиес по углом 12О , Лапки заканчиваютс пеаестками 4, перпендикул рными ппоскости торца цнпкнд .ра.On the other turn, there are three folders 3 spaced at an angle of 12 °. The paws end with feathers 4, perpendicular to the surface of the face of the cnc.

Оправа может использоватьс только дл оптических эпементовр вес асоторых не превышает 0,5 кг.The frame can only be used for optical devices that do not exceed 0.5 kg.

Оправа работает следующим образом.The frame works as follows.

Оправа ввинчиваетс в юстировочноё устройство до касани нижними торнами лепестков 4 плоскости юстировочного устройства. Зеркало вставл етс между лапками до упора в торец цилиндра 1, который служит основанием. При довинчивании опрешы лепестки, упира сь в nnockocTb юстировочного устройства, деформируют лапки Зо При этом лапки, отклон ютс к оси оправы и зансшиают зеркало по боковой цилиндрической поверхности .The frame is screwed into the adjusting device until the lower torn petals 4 touch the plane of the adjusting device. The mirror is inserted between the legs until it stops at the end of the cylinder 1, which serves as the base. When screwing up the opres, the petals, resting against the nnockocTb of the adjustment device, deform the paws of Zo. At the same time, the tabs are deflected to the axis of the rim and zanshshiruyut the mirror along the lateral cylindrical surface.

Claims

On the right, it provides a convenient and easy mounting of the optical element. Invention Formula

On the right for mounting a replaceable circular optical element comprising a base and a fastening element in the form of a three; Petals located at an angle of 12 ° to each other, characterized in that, in order to simplify the mounting of the optical element, the base and the fastening element are made in one piece, which is a cylinder whose diameter is smaller than the diameter of the optical element, with a thread on the side surface having three husks at an angle of 120 ° at the end, with the legs inclined from the plane of the cylinder at an angle of 2-4, and the petals are made at the ends of the legs perpendicular to the plane of the end of the cylinder.
