Description

(54) СПЕКТРАЛЬНАЯ ЩЕЛЬ(54) SPECTRAL SLOT

Изобретение относитс к оптическому приборостроению и может быть использовано в различных спектральных приборах.The invention relates to optical instrumentation and can be used in various spectral instruments.

Известны спектральные щели, содержаидае корпус, ножи и механизм раскрыти 1.Spectral slots are known, comprising a housing, knives, and a disclosure mechanism 1.

Однако они обладают нестабильностью обратного хода вследствие значительных сил трени в механизмах, а также ненаде даы в,работе при использовании в вакуумных спектральных приборах .However, they have the instability of the reverse stroke due to the significant forces of friction in the mechanisms, as well as not needed in the work when used in vacuum spectral devices.

Наиболее близкой к предложенной па техническому решению вл етс спектральна щель, содержаща ножи и механизм раскрыти , выполненный в виде двух рычагов, ведущего и ведомого, оси поворота которых разнесены и параллельны друг другу, и задающего звена 2Т.Closest to the proposed pa technical solution is a spectral slit containing knives and a disclosing mechanism, made in the form of two levers, the master and the slave, the pivot axes of which are spaced apart and parallel to each other, and the master link 2T.

Однако указанна спектральна щель дл обеспечени подвижности двух ножей щели требует применени двух механизмов раскрыти , что усложн ет конструкцию и снижает точность согласовани задающих звеньев, вследствие чегс снижаетс точность и воспроизводимость раскрыти щели, а такжеHowever, this spectral slit requires the use of two opening mechanisms to ensure the mobility of the two knives, which complicates the design and reduces the matching accuracy of the driver links, resulting in reduced accuracy and reproducibility of the slit opening, as well as

надежность работы, особенно -в услови х вакуума.reliability of operation, especially in vacuum conditions.

Цель изобретени - повышение точност и согласовани и воспроизводимости раскрьати двух ножей, надежности работы в услови х вакуума, а также уменьшение габаритов при .работе в услови х вакуума.The purpose of the invention is to improve the accuracy and consistency and reproducibility of the cutting of two knives, the reliability of work under vacuum conditions, as well as the reduction of dimensions when working under vacuum conditions.

Поставленна цель достигаетс The goal is achieved

10 тем, что в спектральной щели, содержащей ножи и механизм раскрыти , выполненный в виде двух рычагов, ведущего и ведомого, оси поворота которых разнесены и параллельны друг 10 in that in the spectral slit containing the knives and the disclosure mechanism, made in the form of two levers, the master and the slave, whose pivot axes are spaced apart and parallel to each other

15 дфугу, и задающего звена, ведомый рычаг шарнирно закреплен на конце, противолежащем ножу, и снабжен пр молинейной направл ющей, расположенной между ос ми поворота рычагов, а ве20 дущий рычаг снабжен наконечником, контактирующим с указанной направл ющей .15, and the driver link, the driven lever is hinged at the end opposite the knife, and is provided with a linear guide located between the axes of the lever's rotation, and the blowing lever is provided with a tip in contact with the specified guide.

Оба рычага выполнены в форме полых полуцилиндфов.Both levers are made in the form of hollow semi-cylinders.

Claims

Figure 1 shows the principal construction of a slit with two movable knives; Fig. 2 shows the spatial arrangement of the elements of the slot adapted for use in vacuum devices with smart devices. Knives 1 and 2 are fixed on bearing arms 3 and 4, the pivot axes of which are both spaced and parallel 0 -0, you are to each other. The driving lever 3 has a spherical tip 5, which is in contact with the rectilinear guide 6 of the output lever 4. The lever 4 is pivotally fixed in the housing (not shown with the end opposite the knife 2. The driver link 7, made in the form of a pusher or a swinging lever, interacts with a spherical tip 8 on the lever koHue 3. A spring 9 is installed to create the closing force of the slit 9. The levers 3 and 4 are made in the form of hollow semi-cylinders The device works as follows: The driver link transmits the movement to the driving lever 3 through $ 1 terminal 8 When the lever 3 rotates around the axis O-O, the opening force through the tip 5 is transmitted through the guide 6 to the driven lever 4, which allows the two knives to move simultaneously and open the slot. The levers in the form of hollow semi-cylinders make it possible to reduce the size and place the gap inside the socket vacuum device. The design provides a high consistency and linearity of the opening of the two knives. Reducing the number of moving parts and friction pairs provides better reproducibility of the opening of the slit, and akzhe improves reliability and performance gap, especially in vacuo. Claim 1. Spectral slit, comprising a knob and a disclosing mechanism, made in the form of two levers, a master and a slave, whose pivot axes are spaced apart and parallel to each other, and a driver link, which, in order to improve the accuracy of matching and the reproducibility of opening the knife knives, as well as the reliability of operation in vacuum conditions, the driven lever is hinged at the end opposite the knife, and is equipped with a straight guide located between the axes of the lever rotation, and the driving lever is equipped with tips com, in contact with the specified direction kndy. 2. The spectral slit according to claim 1, wherein, in order to reduce overall dimensions when operating under vacuum conditions, both levers are made in the form of hollow semi-cylinders.
