Abstract
The utility model disclose a grating fixing and adjusting device comprising a grating seat and a grating seat support which is connected with a driving device. The grating seat support includes a fixing groove applied to fix the grating and a rotating shaft. The grating seat is fixed with the grating seat support through the rotating shaft and a connecting section is arranged at the geometric centre of the fixing groove and the rotating shaft. The rotating shaft is provided with two screw holes respectively at different positions along the vertical direction and the two adjusting screws are screwed into two screw holes respectively. The utility model can adjust the depression and elevation angles of the grating seat through the adjust screws arranged in the two screw holes. When losing the locking screw, the utility model can also carry on rotating and axial direction adjustment of the grating engraving line direction.The utility model has the advantages of simple structure, and easy operation which can realize multi-dimensional adjustment and avoid the grating stress deformation caused by stress concentration which ensures long-term reliable fastening without loose.
Description
Technical field
The utility model belongs to the exact instrument technical field, refers to that specifically a kind of grating fixes and adjusting gear.
Background technology
Grating and fixed part thereof are one of core components of grating spectrum instrument, and the quality assurance of spectral instrument is had important effect, and the fixedly requirement of grating is fixed on its design attitude reliably with grating, must not become flexible, reliably and with long-term, indeformable.The fixing methods such as pressing plate is fastening, spring compression, epoxy glue cementation that adopt usually of grating, because of the fixing permissible accuracy height of grating, depend merely on processing and be difficult to reach requirement, how the fastening method of spring compression and pressing plate need be provided with complicated adjustment structure, and the method for epoxy glue cementation makes grating produce stress deformation easily.
The utility model content
The purpose of this utility model is to provide a kind of simple in structure, easy to operate, bounding force small and scatteredly to make grating not produce stress deformation, reliable fastening grating is fixed and adjusting gear.
For achieving the above object, a kind of grating of the utility model is fixed and adjusting gear, form by grating seat and grating seat support, the grating seat support is connected with drive unit, described grating seat comprises pickup groove and the rotating shaft that is used for fixing grating, described grating seat fixes by rotating shaft and described grating seat support, the geometric center place of described pickup groove and rotating shaft is provided with linkage section, and vertically diverse location place is provided with two screw holes respectively in the described rotating shaft, and two adjust screws screws in respectively in described two screw holes.
Further, described pickup groove sidewall is evenly equipped with the open-work that several are used for gluing.
Further, be evenly equipped with the open-work that several are used for gluing on the described pickup groove bottom surface.
Further, described grating seat support be provided with the fixed orifice that is complementary with described rotating shaft and with stretch out from this fixed orifice and run through the locking slot of grating seat support sidewall, described rotating shaft is arranged in described fixed orifice, and described lock-screw passes locking slot grating seat support and rotating shaft are fixed.
Because the utility model is made up of grating seat and grating seat support, described grating seat comprises pickup groove and the rotating shaft that is used for fixing grating, the geometric center place of described pickup groove and rotating shaft is provided with linkage section, vertically diverse location place is provided with two screw holes respectively in the rotating shaft, therefore can adjust the high angle of bowing of grating seat by the adjustment screw that is arranged in two screw holes, unclamp lock-screw, make the relative grating seat support rotation of grating seat, also can carry out the rotation adjustment and the axially adjustment of grating portrayal line direction, simple in structure, can realize the multidimensional adjustment, easy to operate, easily grasp; In addition, because pickup groove sidewall and bottom surface are evenly equipped with the open-work that several are used for gluing, therefore, grating is adhered on the grating seat through a plurality of dispersions, uniform open-work gluing, avoided stress to concentrate and make grating to produce stress deformation, and guarantee fastening reliably and with long-term, loosening.
