The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of motorized adjustment stand for optical lens that corner in the optical path adjusting is uncertain and produce the optical axis coupling phenomenon that overcome is provided.
Solution of the present utility model is: a kind of motorized adjustment stand for optical lens, comprise picture frame, be positioned on the middle catoptron of picture frame, regulate the regulating device of picture frame, regulating device is connected by spring with picture frame, rotating shaft position at picture frame is provided with spacing hole, there is a manual screw thread pair to reach in the spacing hole on the regulating device, wherein: regulating device comprises mainframe, be connected to orientation regulating electric machine and pitch regulation motor on the mainframe, respectively by orientation shaft coupling and the pitching shaft coupling of orientation regulating electric machine and pitch regulation driven by motor, orientation screw thread pair and the pitching screw thread pair controlled by orientation shaft coupling and pitching shaft coupling respectively, it is characterized in that orientation screw thread pair front end is connected with the orientation orienting lug, the orientation orienting lug inserts in the orientation gathering sill of the picture frame that matches with it; Pitching screw thread pair front end is connected with the pitching orienting lug, and the pitching orienting lug inserts in the pitching gathering sill of the picture frame that matches with it.
The course of work of the present utility model is: during pitch regulation, pitch regulation driven by motor pitching shaft coupling and pitching screw thread pair rotate together, regulate the luffing angle of stand for optical lens, the pitching screw thread pair is limited in the pitching gathering sill, direction motion in one dimension along gathering sill, after reaching the luffing angle that needs, control system is locked with pitching motor, guarantees that current angle is held.The light path angle of pitch is regulated complete, and azimuth adjustment and the angle of pitch are regulated similar.
Orientation orienting lug and pitching orienting lug are the V-type orienting lug in the solution of the present utility model, be the V-type opening part near screw thread vice division chief namely, inserting the gathering sill front end is that V-type is most advanced and sophisticated, and orientation gathering sill and pitching gathering sill are complementary with orientation orienting lug (15) and pitching orienting lug (11) respectively.Its effect is to guarantee that further screw thread pair is limited in the gathering sill, along the direction motion in one dimension of gathering sill, avoids producing the optical axis coupling phenomenon.
Distinguish connection orientation displacement transducer and pitching displacement transducer at orientation screw thread pair and pitching screw thread pair in the solution of the present utility model.Its effect is that control program automatically performed after motor and displacement transducer powered up, and motor is sought zero point under the cooperation of displacement transducer.During pitch regulation, pitch regulation driven by motor pitching shaft coupling and pitching screw thread pair rotate together, regulate the luffing angle of stand for optical lens, the pitching screw thread pair is limited in the pitching gathering sill, direction motion in one dimension along gathering sill, after reaching the luffing angle that needs, do not produce coupling phenomenon, the move distance of pitching displacement sensor stand for optical lens, be presented in real time in the control system after converting angle to, after reaching the luffing angle that needs, control system is locked with the first motor, guarantees that current angle is held.The light path angle of pitch is regulated complete, and azimuth adjustment and the angle of pitch are regulated similar.
Connect the manual adjustments handle in the solution of the present utility model on the mainframe, manual adjustments handle control hand thread is secondary.Its effect is can regulate by the manual adjustments handle gap of picture frame and regulating device in the angle of pitch, azimuth adjustment.
Advantage of the present utility model: the utility model is connected with the orientation orienting lug at orientation screw thread pair front end, and the orientation orienting lug inserts in the orientation gathering sill of the picture frame that matches with it; Pitching screw thread pair front end is connected with the pitching orienting lug, and the pitching orienting lug inserts in the pitching gathering sill of the picture frame that matches with it.The corresponding screw thread pair that guarantees is limited in the gathering sill, along the direction motion in one dimension of gathering sill, avoids producing the optical axis coupling phenomenon.By distinguishing connection orientation displacement transducer and pitching displacement transducer at orientation screw thread pair and pitching screw thread pair, motorized adjustment stand for optical lens of the present utility model has realized automatic regulation function, avoided manual adjustments inconvenient, precision is difficult to the shortcomings such as control, during optical path adjusting, only produce motion in one dimension between picture frame and the screw thread pair, avoid conventional electric to regulate and produced the phenomenon that two dimensional motion causes the optical axis coupling in the stand for optical lens optical path adjusting, simultaneously, displacement transducer is to mirror angle position Real-Time Monitoring, so that catoptron is more directly perceived and be convenient to control when forward angle and the angle of pitch.
