Abstract
The utility model discloses a left and right precision adjusting device base on eccentric shafts, the device comprises the eccentric shafts and an emitting slit in a mutually vertical arrangement, the device is characterized in that the eccentric shaft comprises an inner ring and an outer ring, and mutual positions of the inner ring and the outer ring are adjusted through rotation; two ends of the emitting slit are respectively and fixedly connected with end portions of the inner rings, and the eccentric shaft passes through a mounting base and an outer ring end portion and extends outwards; the outer ring end portion is provided with a gap for indicating an adjusting position; and the mounting base is provided with a fastening screw for fixing the eccentric shaft, the fastening screw and the eccentric shaft are vertically arranged, one end of the fastening screw is exposed outside the mounting base, and the other end of the fastening screw passes through the mounting base and extends to an outer surface of the eccentric shaft. The left and right precision adjusting device base on eccentric shafts is simple in structure and easy in adjustment, fast adjustment of multi-channel single slits is realized, and consistency of the multi-channel single slits is also realized.
Description
Technical field
The utility model relates to a kind of left and right sides device for precisely regulating based on excentric shaft.
Background technology
The exit slit of spectrometer is light outgoing window on the Rowland circle track after the concave grating diffraction focuses on.According to the light-dividing principle of concave grating, the angle of different wavelength outgoing is fixed.The position goodness of fit of exit slit and emergent light is higher, and the effect that the detector of exit slit back is surveyed is better.With the exit slit device of single slit, the position of every slit all is independently, and installation is affirmed with the position of actual emergent light inconsistent, and this just need to carry out minute adjustment to the position, the left and right sides of exit slit.In addition, in the multichannel spectrometer, because passage is many, debugging cycle is long, must adopt rational adjustment structure to realize the adjusting of single slit, realizes the consistance of a plurality of passage list slits.
The utility model content
Purpose: in order to overcome the deficiencies in the prior art, the utility model provides a kind of left and right sides device for precisely regulating based on excentric shaft, and is simple in structure, easy to adjust, can realize that the quick adjustment of a plurality of passage list slits makes it reach consistance.
Technical scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Based on the left and right sides device for precisely regulating of excentric shaft, comprise mutual vertically disposed excentric shaft and exit slit, it is characterized in that: described excentric shaft comprises inner ring and the outer ring of regulating the mutual alignment by rotating; The two ends of described exit slit are fixedly connected with the inner ring end respectively, and described excentric shaft passes end, mount pad outer ring and exposes.
End, described outer ring is provided with the breach that is used to indicate adjusting position.
Be provided with the holding screw for fixed eccentric shaft on the described mount pad, described holding screw is vertical with excentric shaft to be arranged, and an end exposes to mount pad, and the other end passes the outside surface that mount pad extends to excentric shaft.
Also be provided with on the described mount pad for the installation recess that connects with the Rowland circle track and corresponding mounting screw.
Beneficial effect: the left and right sides device for precisely regulating based on excentric shaft that the utility model provides, simple in structure, easy to adjust, can realize that the quick adjustment of a plurality of passage list slits makes it reach consistance.
Description of drawings
Fig. 1-2 is structural representation of the present utility model;
Fig. 3-4 is the structural representation of excentric shaft.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Be depicted as a kind of left and right sides device for precisely regulating based on excentric shaft such as Fig. 1-2, comprise mutual vertically disposed excentric shaft 1 and exit slit 2, excentric shaft 1 comprises inner ring 3 and the outer ring 4 of regulating the mutual alignment by rotating; The two ends of exit slit 2 are fixedly connected with inner ring end 5 respectively, and described excentric shaft passes end, mount pad 8 outer ring 6 and exposes; End, outer ring 6 is provided with the breach 7 that is used to indicate adjusting position; Be provided with the holding screw 9 for fixed eccentric shaft on the mount pad, holding screw 9 and excentric shaft 1 vertical setting, an end exposes to mount pad, and the other end passes the outside surface that mount pad 8 extends to excentric shaft; Also be provided with on the mount pad 8 for the installation recess 10 that connects with the Rowland circle track and corresponding mounting screw 11.
The utility model is based on excentric shaft 1 to be come minute adjustment is carried out in the position, the left and right sides of exit slit 2; Be the structure of excentric shaft as shown in Figure 3-4, the outer ring 4 of excentric shaft is the secured adjusted face, can regulate about the hole; Inner ring 3 is adjusting ranges, and the end is fixedly connected with exit slit 2; Come adjusting position by rotating outer ring 4 in the actual debug process, the left and right sides position relationship of the central shaft b of adjusting inner ring 3 and the central shaft a of outer ring 4; Because exit slit 2 is fixedly connected with inner ring 3, outer ring 4 is connected with the Rowland circle track by mount pad 8, in fact be exactly to have regulated the mutual left and right sides position relationship of exit slit 2 and Rowland circle track, make the position height goodness of fit of exit slit and emergent light.
During actual the use, exit slit 2 is installed on the Rowland circle track, and eccentric rotation axis 1 can be estimated the position of determining adjusting by the breach 7 of excentric shaft; Regulate complete after, with holding screw 9 that excentric shaft 1 is fixing, like this, exit slit has just fixed.
The above only is preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
