Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail.
A kind of optical axis electric adjusting mechanism, as shown in Figure 1, comprise supporting component 4 and adjusting part 3, described supporting component installs adjusting part, laser lamp 1 is installed by mounting panel 2 in the front end of this adjusting part.
The structure of described supporting component as shown in Figure 2, comprise substrate 5, side stand 6 and rear stand 8, the both sides of described substrate are fixedly mounted with the side stand vertically arranged for a pair, the substrate end-face rear portion of respective side stand is fixedly mounted with rear stand, left and right outside mounting limit switch 7A, the rear stand arranged on left and right sides mounting limit switch 7B of corresponding limit switch 7A respectively of described side stand.
The structure of described adjusting part is as shown in Fig. 3, Fig. 4, Fig. 5, comprise the dynamic plate 9 of isosceles right triangle structure, rectangular configuration determine plate 10, motor 13A and motor 13B, described dynamic plate and determine the parallel longitudinal interval of plate and arrange, this dynamic plate and the edge setting-in detent ball 14 determined between plate, to should detent ball dynamic plate and determine the transverse direction of plate and vertical direction is all shaped with two pairs of circular holes 21, in each circular hole, radial direction is fixedly mounted with straight pin 15, by installing extension spring 20 between corresponding straight pin thus by dynamic plate and determine plate and link together, in the middle part of described outer face of determining plate, longitudinal separation is fixedly mounted with two leads 12, as shown in Figure 4, plate diagonal of determining outside corresponding two leads is fixedly mounted with thread bush 17 respectively, as shown in Figure 7, this thread bush internal thread connection for transmission axle 11, the little ball 18 of pressure one pushes up respectively and between the inboard end face of dynamic plate in the inner end portion of each power transmission shaft, the dynamic plate inner end of corresponding described little ball is shaped with elongated hole 24, as shown in Figure 6, in each elongated hole, a pair alignment pin 19 is installed, the outer end of described power transmission shaft and the output shaft of described motor are solidly installed, the installing hole of this motor respectively slip cap is contained on lead.In order to prevent little ball from deviating from, the end of described power transmission shaft is the circular hole holding little ball.
As shown in Figure 6, its right angle is shaped with the circular hole 22A holding detent ball to the structure of described dynamic plate, and the middle part of dynamic plate is shaped with three connecting holes 23 for installing laser.
As shown in Figure 7, one edge is shaped with the circular hole 22B holding detent ball to described structure of determining plate, and the transverse direction of this circular hole and vertical direction are shaped with the two pairs of circular holes installing straight pin.
The optical axis of mechanism regulates and realizes in the following way:
As shown in Figure 8,9, 10, motor 13A level of control X to, X is to being left and right; Motor 13B control vertical Y to, Y-direction is upper and lower; When after electric machine rotation, power transmission shaft can rotate thereupon, and motor is along the axial motion of lead, after motor output torque is delivered to power transmission shaft, because of power transmission shaft and thread bush threaded engagement, the output torque of such motor changes the turning moment of power transmission shaft into, makes power transmission shaft precession or back-out; During power transmission shaft 12 precession, the precession displacement of power transmission shaft is passed to dynamic plate by the little ball of front end, because dynamic plate is be connected the morning by extension spring with determining plate, so dynamic plate will produce centered by detent ball 14 away from the movement tendency determining plate, this trend is that plate is that motionless datum mark departs from the angle a or b that determine plate with detent ball, in addition detent ball and two little balls are determine three strong points that plate is connected with dynamic plate, hang fixing by X and Y-direction four extension springs; When the precession displacement of power transmission shaft becomes large, angle a or b becomes large, and little ball can produce slide displacement, to adapt to the angle deviating of dynamic plate away from dynamic plate between two alignment pins simultaneously; The laser lamp optical axis being for this reason fixed on dynamic plate changes accordingly, produces the effect that the optical axis regulates.
Be no matter regulate horizontal X to or vertical Y to, determine plate to maintain static all the time, dynamic plate produces the change of a or b angle around detent ball, and the change of a or b angle is independent of each other, can change, for this reason by the regulating effect in generation 8 directions, (in figure, "+" is motor rotating forward as shown in Figure 10 simultaneously, "-" is motor reversal), specific as follows:
1) when motor 13A rotates forward, the laser lamp optical axis deflects to the left;
2) when motor 13A reverses, the laser lamp optical axis deflects to the right;
3) when motor 13B rotates forward, the laser lamp optical axis deflects upward;
4) when motor 13B reverses, the laser lamp optical axis deflects downwards;
5) when motor 13A rotates forward, 13B reverses, the below deflection left of the laser lamp optical axis;
6) when motor 13A rotates forward, 13B rotates forward, and the laser lamp optical axis deflects to upper left side;
7) when motor 13A reverses, 13B reverses, and the laser lamp optical axis deflects to the right;
8) when motor 13A reverses, 13B rotates forward, and the laser lamp optical axis deflects to upper right side.
In addition, the adjustable-angle of the laser lamp optical axis is limited within the specific limits by switch 6, motor 13A and 13B does round rectilinear motion along lead, when motor front end face or rear end face touch limit switch (7A, 7B), triggering limit switch is produced a signal of telecommunication, now motor stalls, reaches the maximum of adjustment or minimum angles, and therefore limit switch is the limit point of angular adjustment.
For preventing equipment because of the impact that ambient vibration brings under powering-off state, motor possesses certain self-lock ability, can not cause electric machine rotation, and then affect properties of product because of vibration.
The output torque of motor changes the turning moment of power transmission shaft into, make power transmission shaft precession or back-out, dynamic plate by produce centered by detent ball away from or near the movement tendency determining plate, simultaneously motor possesses certain self-lock ability, prevents equipment under powering-off state because of electric machine rotation that ambient vibration causes.The utility model structure is simple, reasonable in design, easy to operate, and can realize Long-distance Control, and achieve job site debugging, what effectively improve watch-dog shoots with video-corder quality, has the value of wide popularization and application.
It is emphasized that; embodiment described in the utility model is illustrative; instead of it is determinate; therefore the utility model comprises the embodiment be not limited to described in embodiment; every other execution modes drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope of the utility model protection equally.
