Abstract
The utility model provides an adjustable mirror holder of two dimension based on curved surface location, this scheme is including primary mirror frame, locking ring and picture frame, the picture frame cover is in the primary mirror frame, the one side and the primary mirror frame of picture frame are connected, and the outside cover of opposite side has the locking ring, the interior edge of primary mirror frame is provided with the internal thread, the outer edge of locking ring is provided with the internal thread assorted external screw thread that puts up with the primary mirror, locking ring and the primary mirror threaded connection that put up, be provided with the lens in the picture frame. During two -dimentional adjustable optical lens frame can be solved to this scheme, structural stiffness was low, was difficult to improve the anti -resonance stability of mirror holder, especially to low frequency vibration's resonance scale -up problem. The practice shows that this utility model can effectively improve mirror holder structure base frequency, can guarantee that the lens winds the accurate two -dimentional angular adjustment of x axle and y axle, improves mirror holder structural stability simultaneously again.
Description
Technical field
The utility model relates to precison optical component integration techno logy, especially a kind of adjustable mirror holder of two dimension based on curved surface location。
Background technology
In the prior art, known technology is, the two-dimentional adjustable optical mirror holder commonly used at present, and rigidity is low, and resonant frequency is low, under random vibration environment, it is easy to producing mesomerism, and then affect beam Propagation precision, this is the weak point existing for prior art。
Utility model content
The purpose of this utility model, it is aiming at the deficiency existing for prior art, and the technical scheme of a kind of adjustable mirror holder of two dimension based on curved surface location is provided, the program can solve the problem that in two dimension adjustable optical mirror holder, the rigidity of structure is low, it is difficult to improve the anti-resonance stability of mirror holder, the especially resonance scale-up problem to low-frequency vibration。Practice have shown that, this utility model can be effectively improved Mirror frame structure fundamental frequency, can guarantee that again the eyeglass accurate two dimension angular adjustment around x-axis and y-axis simultaneously, improves Mirror frame structure stability。
This programme is achieved by the following technical measures:
A kind of adjustable mirror holder of two dimension based on curved surface location, includes main glasses holder, retaining ring and picture frame；Picture frame is enclosed within main glasses holder；The side of picture frame is connected with main glasses holder, is cased with retaining ring outside opposite side；The interior edge of main glasses holder is provided with female thread；The outer of retaining ring is provided with the external screw thread that the female thread with main glasses holder matches；Retaining ring and main glasses holder are threaded connection；Eyeglass it is provided with in picture frame。
Preferred as this programme: be provided with on main glasses holder around X-axis governor motion with around Y-axis governor motion。
Preferred as this programme: the top of main glasses holder is provided with the retaining mechanism for driving retaining ring。
Preferred as this programme: be provided with cotter slot in main glasses holder；Picture frame arranged outside has pin；Picture frame coordinates fixing with main glasses holder by pin and cotter slot。
Preferred as this programme: the negative camber of main glasses holder is identical with the radius of curvature of the positive camber of picture frame and the interior positive camber of retaining ring。
Preferred as this programme: the interior positive camber fit clearance adjustable extent of main glasses holder and retaining ring and picture frame is between 0.01mm-0.1mm。
Preferred as this programme: be provided with eyeglass pressure ring between picture frame and eyeglass。
The beneficial effect of this programme can be learnt according to the narration of such scheme, owing in main glasses holder in this scenario and retaining ring and picture frame, positive camber fit clearance and pretightning force drive retaining ring adjustment by retaining mechanism, realize reliable installation of picture frame with eyeglass is fixed, achieve increasing substantially of Mirror frame structure integral rigidity, namely improve the fundamental frequency of Mirror frame structure, avoid the low-frequency resonance of structure, improve optical stability。Test shows, applies the adjustable mirror holder of this curved surface compared with not using, and when identical random vibration environment, mesomerism fundamental frequency can improve more than 70%。
As can be seen here, this utility model compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent from。
