Description
Technical field
The utility model relates to a kind of optical instrument, particularly relates to a kind of bracing or strutting arrangement of optical mirror slip.
Background technology
The bracing or strutting arrangement of present optical mirror slip generally is to adopt oscillating bearing and vertical double sided slider bar supporting way in bottom of device, adopt push rod to carry out rotating adjusting above perpendicular to the trace of the bidimensional on the optical axis direction, because oscillating bearing is positioned at bottom of device with vertical double sided slider bar, the height of center of eyeglass is higher, is unfavorable for the comparison and detection with like product; The installation way of eyeglass adopts V-type to support, and the contact area of clamping device and eyeglass is little, and there are the shortcoming that stress is concentrated, the eyeglass distortion is bigger in eyeglass and fulcrum place.
The utility model content
Technical problem to be solved in the utility model provides the bracing or strutting arrangement of a kind of height of center that can reduce eyeglass to greatest extent, optical mirror slip that the eyeglass deflection is little.
The technical scheme that the utility model technical solution problem is adopted is: the bracing or strutting arrangement of optical mirror slip, comprise regulating device, micromatic setting, mirror holder supporting component, component of frames and portal frame, component of frames hangs on the mirror holder supporting component, and the mirror holder supporting component is suspended on the portal frame by regulating device.
The beneficial effects of the utility model are: because micromatic setting is regulated the mirror holder supporting component, component of frames is suspended on the mirror holder supporting component, the acting force of system directly is not added on the component of frames, guarantees to greatest extent that therefore the eyeglass that is installed on the component of frames is indeformable; Regulating device and mirror holder supporting component are arranged on the top of whole device, have reduced the centre-height of eyeglass; Eyeglass adopts band to support, and increases Area of bearing, and stressed even, has solved eyeglass preferably and has concentrated the problem on deformation that causes because of the improper generation stress of clamping.The utility model is specially adapted to the heavy caliber eyeglass, and (φ 〉=450mm) carries out the bidimensional trace on perpendicular to optical axis direction and rotates and regulate (rotational angle≤± 2 °).

Embodiment
As depicted in figs. 1 and 2, the utility model comprises regulating device 1, micromatic setting 2, mirror holder supporting component 3, component of frames 4 and portal frame 5.The component of frames 4 that eyeglass is installed hangs on the mirror holder supporting component 3; Mirror holder supporting component 3 is suspended on the portal frame 5 by regulating device 1; Regulating device 1 realizes the beat motion of mirror holder supporting component 3 on X, Y direction; Micromatic setting 2 makes mirror holder supporting component 3 realize that along the hinge constraint direction beat moves.Because 2 pairs of mirror holder supporting components 3 of micromatic setting are regulated, component of frames 4 is suspended on the mirror holder supporting component 3, and the acting force of system directly is not added on the component of frames 4, guarantees to greatest extent that therefore the eyeglass that is installed on the component of frames 4 is indeformable.
As shown in Figure 3, regulating device 1 adopts a double-strand chain assembly, and the double-strand chain assembly is the axle system that two are perpendicular to one another on the same cross section, retrains the rotation of the both direction vertical with optical axis; Micromatic setting 2 adopts two cover transfer bar mechanisms, realizes that respectively the trace of mirror holder supporting component 3 beat on X, Y direction is regulated, and as shown in Figure 1 and Figure 4, micromatic setting 2 can be regarded slider-crank mechanism as, and crank should be short as far as possible, and running can be more flexible like this.Because mirror holder supporting component 3 and regulating device 1 all place the top of eyeglass bracing or strutting arrangement, therefore, it is lower that the center of lens height can fall.
The different pitch that adopt micromatic setting 2 realize the thickness adjustment to mirror holder supporting component 3, and it is 15 much bigger that the pitch ratio intermediate thread of the handwheel screw 14 among Fig. 4 is overlapped.During coarse adjustment, screw accurate adjustment lock tube 17 earlier, and then rotate coarse adjustment knob 18 and realize; During fine tuning, unclamp accurate adjustment lock tube 17 earlier, and then rotate fine tuning knob 16 and realize.
Be the free balance of energy after making the component of frames 4 that eyeglass is installed hang on the mirror holder supporting component 3, unlikely deflection, the center of gravity of component of frames 4 and mirror holder supporting component 3 should be on the cross section at hinge axis, the center of gravity that mismachining tolerance causes changes and can guarantee by regulating balancing weight 6, balancing weight 6 can be arranged on component of frames 4 back sides, as shown in Figure 1.
As shown in Figure 5 and Figure 6, for the specific pressure that reduces by 3 pairs of regulating devices 1 of mirror holder supporting component excessive, mirror holder supporting component 3 is provided with unloading spring 13, mirror holder supporting component 3 is suspended on the portal frame 5 after linking together with regulating device 1 by unloading spring 13 again, and its landing weight is 1/2nd of mirror holder supporting component 3 weight.Mirror holder supporting component 3 is provided with projection 7, and component of frames 4 hangs on the mirror holder supporting component 3 by projection 7.
As shown in Figure 7, in component of frames 4, the clamping device of eyeglass adopts band 8 to support, band 8 is fixing by the band latch closure 9 that is arranged on the component of frames 4, band 8 matches with the cylindrical of optical mirror slip, reaches comprehensively evenly flexible support, can reduce the distortion of eyeglass to greatest extent.Determine the width and the form of band 8 according to the shape of lens edge, the utilization finite element theory is analyzed and is determined stretching angle and stripping; For guaranteeing the eyeglass reliability of fixation, in component of frames 4, also be provided with supplemental support 10, when losing efficacy, band 8 is used for support lenses, avoid causing the accident; Also be provided with limited block 11 on the axial direction of component of frames 4, supplemental support 10 and limited block 11 do not produce strong effect to eyeglass when band 8 operate as normal.Band 8 can produce anamorphic stretching under the eyeglass action of gravity, cause high generation of center of lens slightly to change, therefore utilize the belt tension principle, the band that is provided with scalable band degree of tightness on component of frames 4 is adjusted structure 12, band is adjusted the height of center that structure 12 can be adjusted eyeglass, by the adjusting range of band adjustment structure 12, determine the envelope angle of eyeglass.
The stress diagram that Fig. 8 is an eyeglass under flexible strip supports, as can be seen, band stress distribution of mean value can not produce that stress is concentrated and the problem of the optical mirror slip distortion that causes.
