The utility model content
For overcome in the prior art fixed aperture and manual adjustments diaphragm in the higher light path of power, regulate inconvenient, regulate dangerous, bearing accuracy is not high and working state of system under deficiency such as should not regulate, simultaneously only realize deficiencies such as single channel adjusting in order to overcome the conventional electric diaphragm, the utility model provides a kind of novel motorized adjustment diaphragm.
The utility model adopts following technical scheme: a kind of motorized adjustment diaphragm comprises motor, baffle plate, outer cover, manual knob, base plate, main frame, shaft coupling, heat radiator, absorption cell, absorption cell support, guide pole, leading screw, infrared tube.Absorption cell and heat radiator are close to the absorption cell support, leading screw passes absorption cell support one end and connects shaft coupling and motor, the other end connects manual knob, they are installed in the main frame together, and guide pole passes behind the main frame coaxial with the gathering sill of absorption cell support top, and infrared tube is positioned over the main frame bottom, main frame and base plate are fastenedly connected, outer cover places on the main frame, and baffle plate is fastened on the outer cover, thereby is assembled into a motorized adjustment diaphragm.
Described motorized adjustment diaphragm can be regulated manual knob, also can control motor and carry out motorized adjustment, realizes manually and electronic two kinds of regulative modes.
Described outer cover cuts some cracks, is used for ventilation and heat.
Described baffle plate adopts brass material, is used for blocking scattered light.
U-shaped groove is cut at the described heat radiator back side, is used for heat radiation.
Described absorption cell adopts graphite material, and front surface cuts into the V-type groove, and the angle of V-type groove and the beam quality of incident light are complementary.
Described guide pole is used for absorption cell support guiding.
Described infrared tube installation site is complementary with the trigger switch of absorption cell support.
Advantage of the present utility model is: motorized adjustment diaphragm of the present utility model, in the optical system debugging, the break-make of light beam is regulated.After motor and displacement transducer powered up, control program automatically performed, and motor is sought zero point under the cooperation of infrared tube.When needs two-way light all is in conducting state, the absorption cell support mediates, when the conducting of needs left light path, the absorption cell support is in location right, when the conducting light paths of needs the right, the absorption cell support is in left position, easy to adjust, the bearing accuracy height, simultaneously, absorption and radiating condition are good, regulate even optical system also can realize the break-make of single channel light, two-way light in working order down.
Description of drawings
The utility model will illustrate by embodiment and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is motorized adjustment diaphragm surface structure synoptic diagram;
Fig. 2 is motorized adjustment diaphragm inner structure synoptic diagram;
Wherein: the 1st, motor 2 is that baffle plate 3 is that outer cover 4 is that manual knob 5 is that base plate 6 is that main frame 7 is that shaft coupling 8 is that heat radiator 9 is that absorption cell 10 is that absorption cell support 11 is that guide pole 12 is leading screws 13,14, the 15th, infrared tube.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1 and Figure 2, motorized adjustment diaphragm of the present utility model comprises motor 1, baffle plate 2, outer cover 3, manual knob 4, base plate 5, main frame 6, shaft coupling 7, heat radiator 8, absorption cell 9, absorption cell support 10, guide pole 11, leading screw 12 and infrared tube 13/14/15.Absorption cell 9 and heat radiator 8 are close to absorption cell support 10, leading screw 12 passes absorption cell support 10, one end connects shaft coupling 7 and motor 1, and the other end connects manual knob 4, and they are installed in the main frame 6 together, it is coaxial with the gathering sill of absorption cell support 10 tops that guide pole 11 passes main frame 6 backs, infrared tube 13/14/15 is positioned over main frame 6 bottoms, and main frame 6 is fastenedly connected with base plate 5, and outer cover puts 3 on main frame 6, baffle plate 2 is fastened on the outer cover 4, thereby is assembled into a motorized adjustment diaphragm.After motor 1 and infrared tube 13/14/15 power up, procedure auto-control motor 1 rotates, motor 1 drives shaft coupling 7 respectively and leading screw 12 rotates together, absorption cell support 10 infrared tube 13 to the left side under the rotation of leading screw 12 drives moves, after the trigger switch of absorption cell support 10 is triggered to left side infrared tube 13, motor 1 stops operating, scrambler record current location, with rear motor 1 motion in the other direction, after being triggered to middle infrared tube 14, motor 1 stop motion, continue to move ahead with rear motor 1 in scrambler records center position, after being triggered to the right infrared tube 15, motor 1 stop motion again, scrambler records current location again, and this process is the location status of accurately locating absorption cell 9.During practical application, find after the null position, motor 1 is placed on different positions with absorption cell 9 under the control of control system, be placed on the left side, the right conducting light paths, left light path is blocked, be placed on the right, the left light path conducting, the right light path is blocked, in the middle of being placed on, the equal conducting of both sides light path, thus realize all-electric accurate adjusting, under special circumstances, can rotation manual knob 4, realize manual adjustments.
