Description
Technical field
The invention belongs to radome Fixture Design technical fields, and in particular to one kind is for Large Radar Antenna cover electricity
Performance test Multi-angle regulating device.
Background technique
Radome electric performance test generally requires test two polarization postures of vertical polarization and horizontal polarization, therefore,
Antenna and antenna house need to carry out two kinds of polarization postures and install, for single support arm turntable, since support arm blocks, such as to covering
All angular domains after must removing antenna house and antenna, turn 180 ° and install test again.
For plate aerial and antenna house, antenna is on strut, and antenna house is on turntable front end ring, antenna house
It can be freely rotated with each angle, fixation is installed after reaching posture.
But for Connectors for Active Phased Array Radar, antenna need to be on the rolling ring of turntable front end.Miniradar antenna house can be with
Radar antenna is mounted in together on the rolling ring of front end, to realize being freely rotated for various angles.But for large-scale radar day
For irdome, since Phased Array Radar Antenna weighs more than 200 kilograms, radar antenna clamp for electrical measurement is added, if again by radar
Antenna house is mounted on the rolling ring of front end, will be more than the maximum capacity of turntable front end rolling ring, so large-scale phased array thunder
The rear end face of turntable is fixedly mounted on generally by fixture up to antenna house.In test process, radome will be realized various
Posture, can only by the way that manually radome and its fixture are first disassembled, after angle needed for antenna and antenna house are rotated,
Radome is installed again, it is comparable time-consuming and laborious, and at least two people operation is needed, testing efficiency is substantially reduced, accounts for
Use human resources.Sometimes need to increase the number of radome disassembly, the chance for causing radome to be collided with
It will increase.
As phased-array radar equipment is more and more, matched Phased Array Radar Antenna cover is also batch production, phase
Control battle array radome electric performance test during, test posture frequently change, therefore, it is necessary to frequently dismantle radome and
Its fixture, it is comparable time-consuming and laborious.
Summary of the invention
The invention aims to solve during Large Radar Antenna cover electric performance test, by dismantling radar antenna
Inefficiency and the damage of colliding with to product caused by cover and its fixture propose a kind of for Large Radar Antenna cover electrical property
Test Multi-angle regulating device.
The present invention is directed to Large Radar Antenna cover electric performance test Multi-angle regulating device, including annular turntable, in the ring
Shape turntable front end has rotatable rolling ring, and antenna is mounted on the rolling ring, which also installs in annular turntable rear end
Have circular sliding rail, mounting ring is installed in rotation on sliding rail by sliding block, U-shaped connection board ends respectively with rolling ring and peace
Fill ring connection；One end of mounting jaw is mounted in mounting ring, and the other end passes through the mesoporous of mounting ring, annular turntable and rolling ring,
It is connect with radome.
Further, the rolling ring, annular turntable, sliding rail and mounting ring are coaxial.
Further, several antenna holders are spaced apart, and are connect with rolling ring, are connect in the other end with antenna at one end.
Further, four sliding blocks with anti-tipping function are uniformly distributed on the slide rail.
Further, the sliding rail is spliced by long and short two sections.
Further, mounting ring is mounted on sliding block by screw.
Further, U-shaped connection board ends are fixed respectively by screw.
Further, the mounting jaw avoids antenna holder installation.
Further, antenna holder is installed by screw.
Further, the rolling ring, antenna, sliding block, U-shaped connecting plate, mounting ring and mounting jaw are rotated around rotary shaft.
The present invention, which takes, installs round sliding rail additional in annular turntable rear end face, installs multiple sliding blocks on sliding rail, then by mounting ring
It is mounted on sliding block by screw, realizes synchronous slide.After radome is mounted in mounting ring in this way, so that it may it rolls,
Simultaneously by U-shaped connecting plate, the mounting ring of the rolling ring of front end and rear end is connected, it is ensured that mounting ring is synchronous with rolling ring
Rotation, to realize that antenna and antenna house turn to any angle, i.e. any attitude.
The utility model has the advantages that present invention eliminates each works that changes posture and must all disassemble radome extremely fixture
Sequence, and rolling ring and mounting ring synchronous rolling can also be controlled by computer, it is time saving and energy saving without manual rotation, it mentions significantly
High testing efficiency.
Mechanism of the present invention is simple and compact, and manufacturing cost is low, convenient for operation, changes radome posture more convenient,
Manpower is saved, the time has been saved, further improves testing efficiency.
Detailed description of the invention
Fig. 1 is the main structure schematic cross-sectional view of Multi-angle regulating device of the present invention；
Fig. 2 is that the right view of Fig. 1 includes abutment portion.
1- radome, 2- antenna, 3- rolling ring, 4- annular turntable, 5- sliding rail, 6- sliding block, 7- mounting ring, 8-U type
Connecting plate, 9- mounting jaw, 10- rotary shaft, 11- antenna holder
Specific embodiment
As shown in Figure 1, rolling ring 3 is the rotary part on annular turntable 4, it is located at 4 front end face of turntable, rolling ring 3 can be around
Rotary shaft 10 rolls, and several antenna holders 11 are mounted on rolling ring 3 at one end through screw, connect in the other end with antenna 2,
It is rotated to which rolling ring 3 is able to drive antenna 2 around rotary shaft 10.
