Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Case study on implementation: as shown in Figure 1; A kind of mounting structure of limit sensors device on antenna rotating platform that surpasses 360 ° of angles; Comprise supporting disk 1; Supporting disk 1 is fixed on the housing of Be Controlled antenna reductor with a plurality of screws (being six among the figure) during installation, on said supporting disk 1, is provided with a circular rotation chute and an interior driving lever 2; Be equipped with one in the rotation chute in supporting disk 1 and rotate slip ring 3; Rotating slip ring 3 is sleeved in the rotation chute; Can in rotating chute, move, slip ring 3 is provided with chute, and the arc length of this chute accounts for 1/3 of slip ring 3 camber lines greatly; A pair of back-moving spring 4 is installed in this chute; Suit one slide block 5 between two back-moving springs 4 is so that the interior driving lever 2 through supporting disk 1 applies a power along the slip ring circumferencial direction to slide block 5, and slide block 5 can slide in slip ring 3 inside, gives back-moving spring 4 pressure of corresponding glide direction; In case the power that adds through the inner interior driving lever 2 of supporting disk disappears, slide block 5 can be on the dynamic balance point that resets under the effect of spring 4 between two springs.Concrete structure is that an aperture is set on slide block 5, the interior driving lever above the bracing frame 12 is inserted in this aperture cooperate, and interior driving lever 2 can drive slide block 5 in slip ring 3 slides within; While is on the opposite of the chute (chute place cambered surface) of slip ring 3; It is the stage casing of other 2/3 camber line of slip ring 3; One outer driving lever 6 is installed is rotated in company with slip ring 3, and (embedding) magnet steel 7 is set in company with slip ring 3 rotations on the opposite of slip ring 3 upper hopper chutes, magnet steel 7 is arranged on the appropriate position that does not process chute on the slip ring 3; Driving lever 6 outsides are equipped with a fixing block 8 outside; Block 8 does not rotate with slip ring 3, when the outer driving lever 6 and the block 8 of rotation collided, through limiting the rotation that outer driving lever 6 limits slip ring 3.Installation site that a kind of preferable structure is a magnet steel 7 and the center, installation site of interior driving lever 2 symmetry, the magnetic pole of magnet steel 7 points to the center of circle of slip ring 3; In the both sides of magnet steel 7, be installed with first Hall element 10 and second Hall element, 11, the first Hall elements 10 and second Hall element 11 respectively and do not rotate with slip ring 3, be fixedly mounted on the reducer output shaft end face of antenna rotating platform horizontal rotating shaft; When magnet steel 7 during in company with slip ring 3 left-right rotation, respectively with first Hall element 10, second Hall element 11 over against the time, magnet steel 7 triggers first Hall element 10, second Hall element 11, produces electric signal, is input in the control device.Block 8 is installed on the speed reduction unit shell of antenna rotating platform horizontal rotating shaft, is fixed, and the outer driving lever 6 that rotates in company with restriction slip ring 3 clockwise or inhour when rotating touches block 8 and stops operating.The particular location of this magnet steel 7: when outer driving lever 6 not with fixed body on block 8 when contacting; Want to guarantee that magnet steel 7 is on the centre position of first Hall element 10 and second Hall element 11 on the reducer output shaft end face that is installed in the antenna rotating platform horizontal rotating shaft, promptly first Hall element 10 and second Hall element 11 are symmetrical set with respect to magnet steel 7.
When assembling, the interior driving lever 2 that the aperture in the middle of slip ring 3 top shoes 5 is aimed in supporting disk 1 chute is inserted in the location, and magnet steel 7 is installed in the preformed hole of slip ring 3, with the position symmetry of interior driving lever 2, promptly accomplishes magnet steel location and installation in the sensor; Then with supporting disk 1 spiral-lock on the reducer output shaft end face of antenna rotating platform horizontal rotating shaft, and require coaxial fixing; The position of on the reducer output shaft end face of antenna rotating platform horizontal rotating shaft, calculating at slip ring 3 magnet steel of installing 7 simultaneously is a mid point, along slip ring 3 circumference symmetria bilateralis a pair of Hall element is installed again, i.e. first Hall element 10 and second Hall element 11.Go up at the speed reduction unit shell (abbreviating fixed body 9 as) of antenna rotating platform horizontal rotating shaft in addition a block 8 is installed, so that the slip ring 3 that is installed in reducer output shaft upper sensor assembly at it clockwise, its driving lever that stretches out 6 can both touch block 8 in the counter rotation.Supporting disk 1 is formed the spacing sensor module structure of angle together with slip ring 3 and the inner parts of installing like this.But how to guarantee that this spacing angle can meet or exceed 360 °, just must try to achieve angle between Hall element 10 and 11 through calculating.
Below confirm with regard to α among Fig. 41, α 2 and α 4 each angle so that can calculate the α 3 between Hall element 10 and 11.
We know supporting disk 1 in sensor module in case confirm that α 1, α 2 and α 4 are respectively changeless so from Fig. 4; The computing formula of the corner of antenna rotating platform is following:
The corner of antenna rotating platform=360 °-(α 1+ α 2)+(α 3-α 4)=360 °-(α 1+ α 2+ α 4)+α 3 obtain through conversion: α 3 >=α 1+ α 2+ α 4;
Conclusion: when angle 3 between two Hall elements 10 and 11 >=outer driving lever 6, block 8 and magnet steel 7 in the shared angle sum of rotation direction (α 1+ α 2+ α 4), the level angle of antenna rotating platform just can meet or exceed 360 °.
That is to say: the level angle of antenna rotating platform is by α 4 decisions.
Specify for example below:
When supposing work; Sensor module follows that reducer output shaft rotates counterclockwise together in the antenna rotating platform horizontal rotating shaft; When being exposed at the outside outer driving lever 6 of sensor module and running into the block 8 above the fixed body 9; As measuring starting point 1, this moment, outer driving lever 6 just no longer rotated with reducer output shaft, was installed in the inner rotation slip ring 3 of supporting disk this moment and will begins and supporting disk 1 (reducer output shaft just) counter-rotation with this point for we; The magnet steel 7 that are embedded in slip ring 3 inside simultaneously will break away from the center of Hall element 10 and 11, draw close to one of them Hall element.When be embedded in the inner magnet steel 7 of slip ring 3 be close to the Hall element 10 drawn close or 11 and through self the magnetic line of force trigger near (over against time) Hall element the time; To remember that through testing circuit tested solid of revolution causes the angle position that Hall element triggers; Be input in the control device, and be made as the extreme position that rotates counterclockwise direction.And the position of this moment is a measurement point terminal point 2, so the angle between measurement point 1 and 2=(α 3-α 4)/2.That is to say: antenna rotating platform forwards to and continues again just to obtain clockwise limit signal along counterclockwise having rotated (α 3-α 4)/2 angles after outer driving lever 6 touches block 8, claims that here (α 3-α 4)/2 are counterclockwise drag angle.
In like manner; Control system continues rotational delay device output shaft with CW; When being installed in driving levers 6 above the inner slip ring 3 of supporting disk above the reducer output shaft 1 this moment and running into the block 8 above the fixed body 9 once more in the other direction, we once more with this point as measuring starting point 3, outer driving lever 6 also no longer reverses with reducer output shaft at this moment; Being installed in supporting disk 1 inner rotation slip ring 3 this moment will begin with fixed body 9 motionless relatively; Rotate and do relative positive dirction, be embedded in the center that slip ring 3 inner magnet steel 7 will break away from Hall element 10 and 11 simultaneously, draw close Hall element to another one wherein with supporting disk 1 (reducer output shaft just).When the magnet steel 7 that are embedded in slip ring 3 inside are close to the Hall element of the another one of drawing close and pass through the magnetic line of force triggering Hall element of self; To remember to remember once more that through testing circuit CW rotates the angle position that reducer output shaft causes that Hall element triggers, and be made as the extreme position that CW rotates.And the position of this moment is a measurement point terminal point 4, and the angle between measurement point 3 and 4 also is=(α 3-α 4)/2 so.That is to say: antenna rotating platform forwards to and continues to have rotated (α 3-α 4)/2 angles along clockwise direction again behind the another side that outer driving lever 6 touches block 8 once more and just obtain clockwise limit signal, claims that here (α 3-α 4)/2 are clockwise drag angle.
Rotate a circle increase angle [alpha] 3-α 4 in the horizontal direction if will just obtain antenna rotating platform clockwise with the hysteresis angle addition that increases counterclockwise.
We are not difficult to find through the analysis of Fig. 5, Fig. 6, and iff is according to the angle calculating between outer shifting block 6 and two sides that block 8 contact, antenna rotating platform can only forward to 360 °-(α 1+ α 2); After having increased drag angle (α 3-α 4), the corner of antenna rotating platform just is increased to 360 °-(α 1+ α 2)+(α 3-α 4).
Our this road α 1, α 2, α 4 can be according to confirming in advance when carrying out the limit sensors design; Suppose: outer shifting block 6 diameters are 2mm, and block 8 is wide to be 4mm, and magnet steel 7 diameters are 3mm; α 1, α 2, the conversion of α 4 between arc length and angle so; Can obtain (α 1+ α 2+ α 4) in 10 °, so when 3 >=10 ° of angle between Hall element 10 and 11, the corner of antenna rotating platform both can be greater than 360 °.
If the angle at place horizontally rotated zero point of motion as antenna rotating platform when control system triggered one of them Hall element of this both direction, and another reciprocal Hall element when triggering the angle at place horizontally rotate exercise end as antenna rotating platform.When the arc length between Hall element 10 and 11 greater than magnet steel diameter, outer shifting block 6 during with block 8 width sums, antenna rotating platform horizontally rotates angle between the origin-to-destination of motion promptly greater than 360 °.
According to teachings of the present invention; Can use other limit switch to replace magnet steel 7 and a pair of Hall element 10 and 11 among the present invention; Reach same function and produce the limit signal hysteresis, and the result that this increase lags behind makes the angle of revolution of tested solid of revolution meet or exceed 360 °.
