Description
(1) technical field
Originally practical to be related to a kind of polarization turntable, more particularly, to a kind of compact high-precision polarization turntable of adjustment height.
It can be applied to Antenna Far Field Auto-Test System, be especially applied to measurement antenna gain, antenna axial ratio and circular polarisation directional diagram
Etc. indexs.
(2) background technique
Far field antenna test macro is by intermediate frequency local oscillator unit, double axle table, polarization turntable, turntable controller, power amplification
Device assembly, power amplifier-frequency multiplier-coupler component, synchronization signal trigger assembly, standard gain antenna, professional test processing analysis
The composition such as software.
For parameters such as radiation characteristic, the gains of correctly testing antenna, it is necessary to there is a suitable antenna measurement field.It is ideal
Antenna measurement field should be one and be capable of providing Electromagnetic Wave on Surface of Good Conductor and irradiate tested antenna farm, actual test environment is not
It is likely to be breached.One would generally specially be built specially for the microwave dark room of antenna measurement, dark indoor main electrical property ginseng
Number is all close to hypothesis testing environment.
In the receiving end of far field antenna test macro, tested antenna is mounted on double axle table table top by user, provider
Position and pitching movement；In the transmitting terminal of far field antenna test macro, standard gain antenna is mounted on polarization turntable table top, is provided
Polarization motion；By turntable controller by two kinds of turntable aggregate motions, the omnidirectional radiation test of antenna can be completed；But this
The kind test mode tested antenna fixed only for receiving end, it is tested after installation if tested antenna overall dimensions change
Antenna cannot be aligned with transmitting antenna.
Therefore, the update of user's subsequent product, and the driving method of adjustment mechanism are considered when design polarizes turntable
And structure type will facilitate polaxis to tie up in short transverse to adjust, be just able to satisfy this demand.
(3) practical content
This practical technical scheme applied to solve the technical problem is:
Standard gain antenna is supported using the four point touching ball slewing bearing with worm rim, uses angle inside polarization shafting
Contact ball bearing Auxiliary support, and setting angle encoder carries out position-force control on polaxis；
Worm component can integrally along worm gear radially or tangentially micro adjustment center away from, reduce the back lash of worm and gear,
Improve the mechanical return difference of polarization shafting, the final positioning accuracy for guaranteeing polarization shafting；Polarization servo motor is mounted on the defeated of worm screw
Enter end, torque is passed into polarization table top through worm gear mechanism, standard gain antenna is driven to rotate by testing scheme.
Lifting assembly passes through 2 fixed pulleys at top, distinguishes suspension lifting table top at the both ends of lifting frame through wirerope
And counterweight support；Lifting platform integral installation polarization component, counterweight support are equipped with 6 clump weights, are used to trim polarization component
Weight, trim control errors are within the scope of the frictional force of sleeve mechanism, and lifting assembly is by lift servo motor through worm and gear
Speed reducer, elevating screw and lifting nut push entire polarization component to move up and down, at the same laser beam can be projected in it is received
On adjustment face, the moving direction and distance of elevating mechanism are guided.
(4) practical feature
When carrying out the test of a variety of receiving antennas, in order to facilitate user to complete center of antenna alignment as far as possible, this
Practical to provide a kind of compact high-precision polarization turntable of adjustment height, the compact high-precision polarization of this adjustment height turns
Platform has the following characteristics that
1. the advantages of turntable bearing and worm and gear driving, is combined together, both by the polarization component of above structure form
There is stronger bearing capacity, and reduces the axial size of polarization；And angular contact ball is mounted in the left end of angular encoder
Bearing carries out Auxiliary support, and the layout type of this polarization shafting flattening can not only under the premise of meeting requirement
The weight of itself stage body is reduced, the weight of clump weight can be also also reduced, finally reduce the overall weight of entire mechanism, so that entirely
Equipment it is small and beautiful, be moved easily and adjustment, improve the efficiency of test, save cost of labor.
2. the polarization component of above structure form is debugged in the early stage due to being mounted with a laser pen on polarization axis
When can make laser beam and polarization axis coincidence error control in allowed limits；Therefore under the guidance of laser beam, be conducive to
Receiving end is tested the installation of antenna, working efficiency can be improved, but this expense can be neglected compared with the cost of whole equipment.
3. the lifting assembly of above structure pattern, on top, configuration is there are two pulley assembly, and this arrangement is by steel wire
The Impact direction at rope both ends changes into the same direction；On polarization table top, after standard gain antenna is installed, stress size
Centainly, can be by way of increasing and decreasing clump weight come the gravity at trim both ends, it can be by increasing and decreasing counterweight for micro trim
To complete；Meanwhile the worm-gear speed reducer of self-locking function is provided in driving mechanism, therefore, do not match at both ends
In the case where flat, the entire stage body that polarizes will not move up and down suddenly, and this configuration mode can reduce the driving power of motor, mention
The safety that high whole equipment uses.
