It is fixed.
During implementing, fixture specifically can be with bolt or screw, when needing to fix supporting surface, then can be with
Bolt or screw are fixed through after adjusting rod and the through hole being opened on adjustable plate by nut；Fixture specifically can be with
For buckle, when needing to fix supporting surface, then buckle can be blocked through after adjusting rod and the pupil being opened on adjustable plate
It is located in the corresponding draw-in groove of buckle, so as to adjusting rod be fixed, and then plays a part of to fix rotary shaft, it is solid in rotary shaft
In the case of fixed, certain supporting surface is also just fixed, and those of ordinary skill in the art can also according to actual needs arrange other
The fixture of form, is not especially limited in the embodiment of the present application.
In the embodiment of the present application, when the adjustable plate is fan-shaped adjustable plate, when, the arc of the through hole opened up on adjustable plate
Shape through hole.
Embodiment two
Fig. 4 is refer to, the embodiment of the present application also provides a kind of test device to be included：
Such as the test bracket 40 described in embodiment one；
Turntable 41, for supporting the test bracket 40 being arranged on the turntable；
Wherein, when the turntable rotates under external force, the test bracket can be driven in a level
Rotate on the plane of reference of face.
In the embodiment of the present application, turntable specifically has three kinds of implementations, and these three implementations are entered separately below
Row description.
The first implementation.
Turntable includes pitching joint and rotary joint, and pitching joint is arranged on the lower section of rotary joint.
When turntable is under the first implementation, when test bracket is arranged on a spinstand, due to test bracket
On already provided with rotary shaft and supporting surface, pitching joint can have been played a part of, then in actual use, then may be used
So that the pitching joint that itself is arranged on turntable is adjusted to level into locked.
Second implementation.
Turntable equally includes pitching joint and rotary joint, and pitching joint is arranged on the top of rotary joint.
When turntable is under second implementation, when test bracket is arranged on a spinstand, due to test bracket
On already provided with rotary shaft and supporting surface, pitching joint can have been played a part of.So, process is being implemented, then may be used
So that the pitching joint that itself is arranged on turntable is adjusted to level into locked.
In the technical program, after being improved to test bracket of the prior art, i.e., set on test bracket
Rotary shaft and supporting surface are put, to play a part of pitching joint.Pitch orientation is carried out survey being set into support being arranged on turntable
During figure test, the testing precision of pitch orientation figure can not only be mentioned, while without entering to turntable of the prior art
Row is improved, it is only necessary to which pitching joint is adjusted to level into locked, so as to reach the technology for reducing manufacturing cost effect
Really.
The third implementation.
Turntable can only include rotary joint, after test bracket is arranged on rotary joint, by rotation
The rotation in joint can drive the rotation of test bracket.
In the embodiment of the present application, no matter turntable adopts any one in above-mentioned three kinds of implementations, to tested
When the pitching angular direction of antenna is tested, such as：Need testing level angle to be θ, when the angle of pitch is the pitch orientation figure of Φ, can pass through
Adjusting rod adjustment rotary shaft rotates on the vertical plane to Φ and locked, then controls phased array antenna by beam-controller
Wave beam starts test system and allows turntable to rotate a circle in horizontal reference plane to angle of pitch Φ, horizontal angle θ, you can measure by
The wave beam of observation line is in the pitch orientation figure that the angle of pitch is Φ, horizontal angle is θ.
In the embodiment of the present application, turntable is used for bearing test support, therefore, the rotary joint of turntable will not be with survey
Try the rotation of the rotary shaft on support and rotate, meanwhile, tested antenna is arranged in rotary shaft and supporting surface, therefore can be avoided
The swing that tested antenna is produced in rotation process, therefore, it is possible to improve the degree of accuracy of pitching pitch orientation test.
Said one or multiple technical schemes in the embodiment of the present application, at least imitates with following one or more technology
Really：
First, due to the technical scheme in the embodiment of the present application, test bracket includes：First side frame, and with first side
The second side frame that frame is oppositely arranged；Rotary shaft, can be rotatably set between first side frame and second side frame；Support
Face, is fixed in the rotary shaft, for supporting the tested antenna being arranged on the supporting surface；Wherein, when the rotary shaft
During by extraneous revolving force, the rotary shaft will rotate, and then drive the supporting surface to rotate, so that described tested
Antenna rotates.I.e. will not be as in prior art, test bracket is used only for supporting tested antenna, and test bracket is being arranged
Carry out on a spinstand in test process, on the one hand because the set location or tested antenna in pitching joint is in rotation process
Swing and measuring accuracy is affected.And in the technical program, rotary shaft and supporting surface are set on test bracket, to rise
It is arranged on the supporting surface that can be rotated to the effect in pitching joint, and tested antenna, so as to avoid tested antenna from rotating
Swing in journey, thus it is possible to the relatively low technology of the degree of accuracy that there is the test of pitch orientation figure in effectively solving prior art
Problem, and then reach the technique effect for improving pitch orientation figure testing precision.
2nd, due to the technical scheme in the embodiment of the present application, test bracket also includes：Angle measurement component, is arranged on institute
First position corresponding with the end of the rotary shaft on the first side frame or second side frame is stated, for measuring the rotation
The anglec of rotation of axle.I.e. in the technical program, the rotary shaft of test bracket can accurately be arranged by angle measurement unit
The anglec of rotation, further up to improve pitch orientation figure testing precision technique effect.
The above, above example is only described in detail to the technical scheme to the application, but implements above
The explanation of example is only intended to help and understands method of the present utility model and its core concept, should not be construed as to of the present utility model
Limit.Those skilled in the art in the technical scope that this utility model is disclosed, the change or replacement that can be readily occurred in,
