Description
Technical field
The present invention relates to a kind of angle regulators more particularly to a kind of high-precision spiral vernier angle to control hinge.
Background technology
The large-scale angled expanding unit such as parabola antenna of satellite or radar during being unfolded to shape it is necessary to have
High precision.For example satellite dish requires expansion form error to be no more than several millimeters in 10 meters long of developed dimension.
This just needs the expanded angle for strictly controlling satellite or radar antenna, the angular error between every two pieces of antenna array even to require
No more than 0.01 °, this needs a kind of angle control technology possessing very high degree of precision.
The equipment of high-acruracy survey angle has optical measuring instrument, universal protractor etc. at present, is surveyed according to different principles
The size of measuring angle.Existing measurement method can accurately measure front angle, however this is only static test, cannot directly control
System and adjusting angle still will produce very big ground error using manual mode adjusting.Need a kind of high-precision energy direct now
The device that angle is adjusted.
Invention content
Goal of the invention：Under the conditions of a kind of wide-angle of high precision ball lead screw offer is provided, spiral fine tuning
High-precision angle adjusts and control hinge.
Technical solution：The present invention includes hinge left support plate, and the hinge left support plate passes through shaft and the right branch of hinge
Fagging connects, and hinge left support plate is internally provided with lead screw transmission mechanism, one end connection scale rotation of the lead screw transmission mechanism
Button, the other end stretch into locking mechanism, and the part for stretching out locking mechanism is contacted with hinge right support plate.
The lead screw transmission mechanism includes screw axis, and the screw axis is connected by the helicitic texture of one end with screw rod
It connects.
The other end of the screw axis connects dialing knob, and the screw rod stretches into locking mechanism, and end is right with hinge
Support plate contacts.
The screw axis is connect by rolling bearing with hinge left support plate.
The dialing knob is equipped with several reticules.
Torsional spring is cased in the shaft, the spring foot of the torsional spring both sides is individually fixed in hinge left support plate and the hinge right side
The lower section of support plate.
Operation principle：Before use, hinge left support plate is located at same axis direction with hinge right support plate, in use, logical
It crosses rotation dialing knob and drives screw axis rotation, and then screw rod is driven in axial direction to advance, to make to contact with screw rod end
Hinge right support plate under the action of torsional spring, rotate a certain angle along shaft, hinge locked by locking mechanism later
Subtended angle completes the adjusting of hinge angle.
Advantageous effect：The present invention will be converted into the control and regulation of hinge angle the adjusting control of length, it is easier to manipulate
And realization, precision can be improved easily by changing ball screw screw pitch；Hinge subtended angle can be adjusted repeatedly, until obtaining acceptable
Target angle can ignore the slight error of hinge manufacture and fit on, more accurately obtain target angle.
Description of the drawings
Fig. 1 is the front view of the present invention；
Fig. 2 is the angle regulating principle figure of the present invention；
Fig. 3 is the locking mechanism schematic diagram of the present invention.
Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1, the present invention includes hinge left support plate 3, hinge left support plate 3 passes through shaft 7 and hinge right support
Plate 9 connects, and hinge left support plate 3 is internally provided with lead screw transmission mechanism, and one end of the lead screw transmission mechanism connects dialing knob
1, the other end stretches into locking mechanism 6, and the part for stretching out locking mechanism 6 is contacted with hinge right support plate 9.Lead screw transmission mechanism packet
Screw axis 2 is included, screw axis 2 is connect by the helicitic texture of one end with screw rod 5, and the other end of screw axis 2 connects dialing knob
1, screw rod 5 stretches into locking mechanism 6, and end is contacted with hinge right support plate 9.
A part for screw axis 2 is polished rod, and a part is helicitic texture, and screw axis 2 passes through helicitic texture and 5 one end of screw rod
Internal thread connection, the other end of screw rod 5 is polished rod, can be stretched into locking mechanism 6, screw rod 5 is matched with locking mechanism 6 for gap
It closes, locking mechanism 6 is fixed in hinge left support plate 3, and locking mechanism 6 makes screw rod 5 only do the linear motion of axial direction, will not
It is rotated with screw axis 2, and hinge is locked after the control angle needed for obtaining, make hinge keep final angle constant, except non-artificial
Unclamp locking mechanism 6.The end of screw rod 5 is contacted with hinge right support plate 9.The rolling that the smooth bar part of screw axis 2 passes through both ends
Bearing 4 is connect with hinge left support plate 3, and the part that screw axis 2 stretches out hinge left support plate 3 is connected through a screw thread dialing knob 1,
Dialing knob 1 divides for 50 reticules, often rotates one division line, and screw axis 2 can be driven to rotate, to driving screw rod 5 to advance or
Certain distance is retreated, dialing knob 1 includes 50 reticules, makes the range accuracy value that every secondary control screw rod 5 moves forward or back more
It is small, it is the 1/50 of a circle.
The screw pitch of screw axis 2 can control the angle of each rotation hinge variation, and screw pitch is smaller, and hinge accuracy is higher.Hinge
Chain left support plate 3 and hinge right support plate 9 are connected by shaft 7, and torsional spring 8, the spring foot difference of 8 both sides of torsional spring are cased in shaft 7
It is fixed on the lower section of hinge left support plate 3 and hinge right support plate 9.Torsional spring 8 is capable of providing the restoring force of hinge subtended angle, makes hinge
Right support plate 9 is tight contacted between with screw rod 5 always, to keep hinge rotation angle adjustable.Meanwhile by each screw rod 5 advance or
The distance δ retreated and 5 lower face of screw rod can also control the angle of rotation for adjusting hinge every time to the distance L of 7 center line of shaft
Degree.
It is illustrated in figure 2 angle regulating principle figure, the relational expression of angle and adjustment length is：
Due to adjustable angle, the coaxiality error of apparatus of the present invention shaft can be eliminated by angular adjustment, device it is main
Precision is influenced by angle and length transition, from formula (1)：
As L=100mm, often adjusting the Length Quantity that 1 ° of subtended angle needs changes is：
Often adjusting the angle that 1mm length changes is：
Lead screw screw pitch is 0.5mm, and dialing knob shares 50 indexing, then often rotates one division dialing knob, screw rod advance or
Backway is
Then rotation one division dialing knob, angle change value are 0.00573 ° every time, and one is read if estimating between scale value,
When turning over 0.1 indexing, then the minimum angles regulated value being likely to be breached is 0.0005 °, has high angular adjustment precision.
Before use, hinge left support plate is located at same axis direction with hinge right support plate, in use, passing through rotating scale
Knob drives screw axis rotation, and then screw rod is driven in axial direction to advance, to make the right branch of the hinge contacted with screw rod end
Fagging rotates a certain angle under the action of torsional spring along shaft.It is adjusted using the measurement of high-precision angel measuring instrument
Angle value, and be compared with desired value, calculate error makes hinge subtended angle as far as possible later by adjusting dialing knob slightly
Target angle is approached, is reduced within the error to permissible range between hinge subtended angle and target angle, and locked by locking mechanism
Dead hinge subtended angle, completes the adjusting and control of hinge angle.
