Description
Technical field: the utility model belongs to the optical lens handoff technique.
Background technology: at optical imagery, accurately measure and tracker in, optical lens is crucial parts.When changing the visual field, the multiplying power mirror group optical axis of switching mechanism and the optical lens optical axis must concern the strict guarantee position that just the switching location is very accurate, and switching time is short as far as possible.Especially aeroplane photography is measured and tracker wants little weight to want light with the volume of optical lens switching mechanism.
The optical lens switching mechanism that uses has guideway switching mechanism and disk switching mechanism now.Guideway switching mechanism is adjusted locating piece through reconditioning, can realize hi-Fix, but its volume is big, complex structure, and environmental suitability is poor, and its feed screw nut kinematic pair efficient is low, and noise is big.Especially can not be in+55～-40 ℃ of temperature ranges operate as normal.
The disk switching mechanism, self-excitation must trim when preventing to locate, and rationally loads damping.Its bearing accuracy depends on the angle measurement accuracy of angle measurement element.System complex is to vibration and shock-sensitive.Under the condition of vibration 5g and impact 15g, can not guarantee accurate location, system's cisco unity malfunction.
It is long that above-mentioned two kinds of switching mechanisms switch positioning time, all more than 5 seconds.
Summary of the invention: the purpose of this utility model is exactly in order to overcome the shortcoming of guideway switching mechanism and disk switching mechanism, to provide a kind of volume little in light weight, and switching time is short, bearing accuracy height, the switching mechanism of environmental baseline wide accommodation.
The utility model comprises DC servo motor 1 as depicted in figs. 1 and 2; Bearing seat 6, its end pass the axle of servomotor 1 and fix with servo electric shell end; Gear 7 is fixed on the axle of DC servo motor 1; Gear 10, the composition gear set matches with gear 7; Pretightning force torsion spring 5, its two ends are that the axle 11 and the axle 17 of an integral body is fixing with gear 10 respectively; Nut 4 is to fix by pin with axle 17 1 ends, and nut 9 is to fix by pin with an end of axle 11, and the end face of nut 9,4 provides spacing workplace to pretightning force torsion spring 5 respectively.Bearing 8 matches with axle 11, and bearing 8 is fixing by screw and bearing seat 6 by bearing cover 13; Axle 17 matches with bearing 2 and bearing 20, bearing 2 pass through bearing cover 15 by screw retention on multiplying power microscope base 19; Multiplying power microscope base 19, its end is fixing with axle 17; Multiplying power mirror group 16, it is fixed on the multiplying power microscope base 19 by pressure ring 18; Locating piece 22 is fixed on the multiplying power microscope base 19; Limited block 23, limited post 21 all are fixed on the pedestal 24; Optoelectronic switch 14 is fixed on the bearing seat 6.
The course of work of the present utility model: DC servo motor 1 driven wheel 7 and gear 10 rotate, so and gear 10 is that holistic axle 11 rotates, pretightning force torsion spring 5 is because all fixing with axle 11, axle 17, so, axle 11 rotates by pretightning force torsion spring 5 axle 17 is also rotated thereupon, thereby multiplying power microscope base 19 is rotated, and the multiplying power mirror group 16 that is fixed thereon is rotated and the incision optical lens optical axis.When multiplying power mirror group 16 enters assigned address, locating piece 22 closely contacts with limited block 23, and meanwhile limited post 21 also closely contacts with the locating surface of multiplying power microscope base 19 synchronously, and multiplying power mirror group 16 is accurately positioned.Optoelectronic switch 14 feeds back to DC servo motor 1 with piezoelectric signal and sends the signal that stops operating to it.DC servo motor still 1 can be rotated further certain angle, thus make pretightning force torsion spring 5 produce designing requirements as 500g moment, thereby the multiplying power mirror is accurately positioned.Because the torque reaction that pretightning force torsion spring 5 produces is much smaller than the self-locking moment of axle 11 and axle 17 moment of frictions and DC servo motor, multiplying power mirror group 16 can not be reversed and its position is kept.Thereby realize the conversion of optical lens visual field.
When DC servo motor was rotated round about, by cooperating with above-mentioned a series of first devices, multiplying power mirror group 16 was also rotated in the opposite direction, thereby makes it and cut out the optical lens optical axis, recovers original visual field.
The beneficial effects of the utility model are: volume is little, has only 60 * 80mm; In light weight, have only 150g; Switching time was short, less than 1 second; Position location precision height can reach 0.005mm, and angle precision reaches 1 '; The environmental baseline wide accommodation can be+55～-40 ℃ of temperature range operate as normal, and system also can normally move under vibration 5g and impact 15g condition.It can be used for the especially airborne optical lens of optical lens and does switching mechanism.
