Abstract
The utility model relates to a two-dimension angular trimming mechanism for a large-caliber reflective mirror, wherein, the center of one side of a mirror frame of a reflective mirror is provided with a ball head which is simultaneously connected with a pedestal movably; the other side of the mirror frame corresponding to the side is respectively provided with screw rods connected with a harmonic motor assembly; with the driving of the harmonic motor assembly, the screw rods simultaneously rotate in the same direction and rotate in the opposite direction, realizing the two-dimensional angular adjustment of the reflective mirror. The trimming mechanism overcomes the shortages that the original adjusting mechanism has large volume and poor stability, and is complicated to install. The utility model can be used for adjusting optical paths.
Description
The utility model is a kind of big mouth mirror catoptron two dimension angular micro-adjusting mechanism, belongs to the optical lens adjusting mechanism.
High-precision heavy-caliber mirror adjustment mechanism in the past mostly is the twin shaft framework, and dimension volume is bigger, less stable.And along with the catoptron bore increases, for improving stability, need to increase the picture frame mounting structure generally speaking, cut should increase the adjustment link; And the increase of adjusting link will cause the increase of structure, therefore often be subjected to the restriction of installation dimension in actual applications.
The purpose of this utility model is to avoid the deficiencies in the prior art, and provide that a kind of structural volume is little, good stability, the highly sensitive large caliber reflecting mirror two dimension angular micro-adjusting mechanism of adjustment.
The utility model can be realized by following technical measures: screw mandrel links to each other with pedestal by ball cover, screw mandrel is by a connection harmonic motor of pedestal assembly, the other end of screw mandrel is installed in certain end on one side of large caliber reflecting mirror picture frame by the bulb nut, the other end of the same edge of picture frame is installed another screw mandrel with same structure, and two screw mandrels drive forward and reverse rotation by separately harmonic motor assembly respectively; One end of the center fixation bulb of the another side that picture frame is relative with this limit, the other end of bulb and pedestal flexibly connect.
The utility model also can be realized by following technical measures: the spring that is placed on the screw mandrel is supported between picture frame and the pedestal.
The utility model has following advantage than prior art: will adjust on the picture frame that link is installed in controlled large caliber reflecting mirror, and make physical dimension restriction very little of micro-adjusting mechanism.Constitute supported at three point by two rhizoid bars and a bulb, improved the stability of micro-adjusting mechanism than the twin shaft framework.Adopt stiffness spring to be supported between picture frame and the pedestal, overcome the accumulation gap error of screw mandrel motion.Adopt harmonic motor assembly and screw mandrel two utmost point transmissions, machinery segmentation and screw mandrel by the harmonic motor assembly produce micrometric displacement, raising institutional adjustment sensitivity, and the I of angular setting sensitivity reaches 0.08 rad.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural drawing of the present utility model.
Fig. 2 is an A-A cut-open view of the present utility model.
In the structural drawing of embodiment of the present utility model as shown in Figure 1, bulb 7 is installed at the center of bottom that the picture frame 1 of large caliber reflecting mirror is housed, and an end of bulb 7 is fixed on the picture frame 1, the other end of bulb 7 and pedestal 5 flexible connections; Picture frame 1 is installed screw mandrel 3 and screw mandrel 9 respectively with respect to the two ends of the top of bottom, forms supported at three point.
Fig. 2 has shown the mounting structure of screw mandrel 3.The mounting structure of screw mandrel 9 is identical with the mounting structure of screw mandrel 3.With the example that is installed as of screw mandrel 3, as shown in Figure 2: one of screw mandrel 3 bulb nut 2 is installed, bulb nut 2 is installed on the picture frame 1 of large caliber reflecting mirror.The other end of screw mandrel 3 is installed on the pedestal 5 by ball cover 4.The good spring 8 of rigidity that is placed on the screw mandrel 3 is supported between picture frame 1 and the pedestal 5, reduces the accumulation gap error of screw mandrel 3 motions.Screw mandrel 3 is near a connection harmonic motor assembly 6 of pedestal 5, and harmonic motor assembly 6 drives screw mandrel 3 and does forward and reverse rotation, promotes picture frame 1 and makes the axial direction of screw mandrel 3 produce displacement, and the machinery segmentation of harmonic motor assembly 6 makes this displacement be subdivided into microdisplacement.When rotating simultaneously with equidirectional under the driving at separately harmonic motor assembly of screw mandrel 3 and screw mandrel 9, the sense of displacement that the two ends of the top of picture frame 1 produce is identical, and picture frame 1 be the deflection of fulcrum generation luffing angle with bulb 7, finishes the luffing angle adjustment.When doing the equal angles rotation simultaneously with mutually opposite direction under the driving of screw mandrel 3 and screw mandrel 9 at separately harmonic motor assembly, one end of the top of picture frame 1 is different with the sense of displacement that the other end produces, driving picture frame 1 is that fulcrum produces orientation angles deflection with bulb 7, finish the orientation angles adjustment, thereby realized the two dimension angular fine setting of large caliber reflecting mirror.
