Abstract

The invention relates to the field of optical spectral instrumentation. The purpose of the invention is to reduce the dimensions. When the screw 11 is rotated, the lever 15 rotates. In this case, the driving units 4, 9 are moved and the springs 5, 10 are deformed, which transfer the intermediate links m 3, 8. On these links are fixed knives 1, 2, 12, 13. Intermediate links 3, 8 are connected with a fixed link 7 by springs 6, 11. The movement of the links 3, 8 will be a fraction of the movement of the links 4, 9, and the knives 1, 2, 12, 13 move in pairs in opposite directions relative to each other with a gear ratio. Leading links 4, 9 are located in a common plane with intermediate links 3, 8 opposite parallelograms. This common plane is perpendicular to the plane of the parallelograms. The small dimensions of the device make the structure less susceptible to external environmental influences. 1 il. (L

This invention relates to optical spectral instrumentation.

The purpose of the invention is the reduction of gabrites.

The drawing shows a schematic diagram of a slot device with two symmetric slots.

The device contains a first slot, delighted with knives 1 and 2, the knife 1 being fixed on the intermediate link 3 of the parallelogram formed by the driving link 4, the flat springs 5 of the leading link 4, the flat springs 6 of the intermediate link 3 and the fixed link 7 (the body), and the knife 2 mounted on the intermediate link 8 of another parallelogram, formed by the driving link 9, the flat springs 10 of the leading link 9, the flat springs 11 of the intermediate link 8 and the fixed link 7 (the body). At the same time, the flat springs 5, 6, 10 and 11 of each of the parallelograms are made separate and placed in parallel planes. The second slit is formed by a knife, mi 12 and 13, and the knife 12 is fixed on the intermediate link 3 parallelogram, and the knife 13 - on intermediate link 8. Between the parallelograms on the axis 14, fixed in the case, there is a lever 15 on which at equal distances x the axes are fixed with rollers 16. The micrometer screw 17c is nutted and the reading device 18 interacts with the lever 15.,.

The device works as follows.

The rollers 16 move the links 4 and 9 parallelograms in different directions. At the same time, the springs 5 and 10 are deformed and the intermediate links m 3 and 8 are transferred, on which 45 knives 1, 2, 12 and 13 are fixed, since the intermediate links 3 and 8 are connected with the fixed link 7 by springs 6 and 11, then the movement is the proportion of the movement of the links 4 and 9. 50 Thus, the knives 1, 2, 12 and 13 move in pairs in opposite directions to each other by equal distances and with the transmitting number, i.e. with a reduction. The forces moving the links 3 and 8 are applied to them evenly from two sides, therefore the links remain parallel to the base contours by using plates of different sizes across the section of the plate.

The small dimensions of the proposed device, in comparison with the prototype, make its structure less susceptible to external influences of the environment (to temperature, vibration, and

Formula invented A slot device containing two parallelograms is located in the same plane and deployed 180 ° relative to each other, each of which includes; leading intermediate and fixed link five 0 five five howl plane of the hull. In the adopted design, the length of the free part of the flat springs 5 and 10 exceeds the length of the free part of the springs 6 and 11, which makes it possible to make the driven elastic contours of the parallelograms several times more rigid than the leading elastic contours of the parallelograms and to provide the necessary gear ratio. The device gives a reduction in size with equal lengths of elastic links by 50% compared with the prototype. The spaced arrangement of the elastic links of the contours allows to reduce the dimensions in excess of these 50%, since the design of the device allows the stiffness of the contours (master and slave) to be separately changed. The size reduction in the device is provided by the separate execution of the leading and driven springs and placing the leading contours of the parallelograms in the spaces of the driven contours, as well as by reducing the length of the drive lever and the housing between the leading and intermediate links of the parallelogram, for which the windows are made. In the device, for example, at the right parallelogram, the leading contour is formed by flat springs 10 leading 9 and intermediate 8 links, and the slave consists of flat springs 11, intermediate link 8, and link 7. Similarly, the elastic contours of the other parallelogram are arranged. Separate execution of the springs leading and driven elastic contours 0 allows varying stiffness contours by using different in cross section plates of the existing assortment of materials. The small dimensions of the proposed device, in comparison with the prototype, make its design less susceptible to external environmental influences (to changes in temperature, vibration, etc.).
