Specific embodiment
In conjunction with embodiment, accompanying drawing, the invention will be further described：
The present invention, because connected mode is unreasonable, is caused for the low slow little AESA detection radar presence now of the type
Antenna element is connected unreliable brought series of problems with antenna array, according to the low slow little AESA detection radar of the type
Needs, devise projective table type stainless steel special fastening screw and the special installation nut of stainless steel.Projective table type stainless steel is special tight
When Gu screw mainly overcomes first the connection that two different types of mode connects for screw are brought from the structure of the screw not
Reliable problem.The structure of projective table type stainless steel trip bolt 3 is as shown in figure 1, the head of screw of projective table type stainless steel trip bolt 3
For flat, boss is provided between thread head and screw rod, the screw thread on screw rod is M4.Head of screw is flat, and middle
Flat recess is provided with, is easy to spanner to clamp when using, flat recess is easily installed, boss is set and is easy to be adjacent to antenna array frame plate 1,
Because the projective table type stainless steel special fastening screw 3 is in design an entirety, thus has very reliable tensile property, only
It is fixed, just firmly itself will can be securely fixed on antenna array framework.And the special installation of stainless steel for designing
Nut primarily to ensure that the connection depth of parallelism that the connection of antenna element and antenna array framework can ensure that between it is 0.05mm,
So, the special surface roughness for installing 4 two end faces of nut of the stainless steel is 1.6, and for the needs installed, by it
Milling is easy to processor to carry out clamping fastener to it into flat.The He of projective table type stainless steel special fastening screw 3 of present invention design
The special nut 4 of installing of stainless steel carries out antenna array and is connected with antenna element just to have accomplished both to have can guarantee that antenna element and antenna frame
Between assembly precision meet depth of parallelism 0.05mm, again can by professional assembler's hand assembled and must also by its assembling experience
Production model be changed into general assembler and can carry out simple fabricated Assembling Production pattern, can more cause low slow little active phase
Control battle array detection radar antenna array passes through vibration test and transport test.The technical solution adopted in the present invention is completed to low
After slow little AESA detection radar assembling, the assembly precision data between acquired antenna array and antenna element are obtained
Design and the accreditation checked.
When former low slow little AESA detection radar installs 128 antenna element on antenna array, according to its mounting surface
Uneven reality, employ laser range finder and measure, by four fixing holes and antenna array in each antenna element
Value of making up the difference between plane is decided (the benefit difference table is referring to table 1).Then according to four fixing holes of 128 antenna element
Value of making up the difference needs, by processor respectively by four stainless steel attachment screws and four stainless steel M5 SOC.HD. cap screws, install
To in four fixed hole positions needed for the antenna element, while processor respectively adjusts it according to the value of making up the difference of this four fixing holes
It is whole to respective value of making up the difference, to meet depth of parallelism 0.05mm that the antenna element installation accuracy reaches design requirement.But, original is adopted
Assembly method is (referring to the attachment structure of accompanying drawing 3)：Each installing hole of the antenna element is by a stainless steel
Special attachment screw, one head is the internal thread of M5, and other end is the screw thread of M4；Enter with the SOC.HD. cap screw of a stainless steel M5
After row connection, the mounting plane of one of fixing hole of four screw holes of an antenna element is formed.In processor by day
When linear array links together with antenna array framework, first by the standard of six sides in a stainless steel attachment screw and a stainless steel
Mode connects for screw together, while being adjusted to mend the value of making up the difference in difference table needed for this screw hole.Because this is by two
The mounting plane that mode connects for screw is formed together, it necessarily occurs some problems, here it is, first, two screws are in connection
During, certain gap is there is in the screw thread between screw and screw, and antenna array is easily caused in this gap for existing
The depth of parallelism between son and antenna array framework does not reach the requirement of 0.05mm.Therefore on, processor connects rear institute together
The mounting plane of formation, in fact, when processor fastens the two screws by matching requirements, as processor tightens the increasing of strength
Plus, the thread pitch between attachment screw and antenna array framework will be pulled out, so as to its necessarily cause antenna element each
The parallel angle value of installation of fixing hole changes, and finally results in and does not reach between the required antenna element of design and antenna array
Depth of parallelism 0.05mm required precision；Second, because when being that the two mounting screws are attached by above-mentioned connected mode,
If just inevitable when finding faulty its some antenna element or unqualified index parameter in antenna array in debugging process
Need to change this antenna element.When processor unloads problematic or faulty antenna element, because by interior six
When square screw unclamps, there is deviation immediately in the precision that can cause four mounting planes in primary antenna a period of time so that antenna array framework
The password of the depth of parallelism 0.05 between antenna element cannot ensure.Now if processor changes good antenna element, should
The plane precision of four fixing holes of antenna element, in addition it is also necessary to which processor constantly enters again according to the value of making up the difference of four fixing holes
Row repeatedly adjustment, can be only achieved the installation accuracy needed for four fixing holes of the antenna element and requires.As long as from this, in the type
There is any problem in any one antenna element on low slow little AESA detection radar antenna array, then processor is with regard to necessary
Antenna element will unload or load onto one by one, while must also incite somebody to action according to the value of making up the difference between antenna array framework and antenna element
It is adjusted to required installation accuracy, can just complete assembling.And this methods by two attachment screw connections are also difficult to
By vibration test and transport test, the user for returning from now on is changing the low slow little Connectors for Active Phased Array Radar antenna element of the type
Bring many troubles and inconvenience.
Therefore the low slow little AESA detection radar antenna array framework and some antenna array of upper currently designed employing
When son is attached, only rely in 4 standards M5 six side's stainless steel screws and 4 special attachment screws to connect due to existing
The method for connecing, what the antenna element brought loosened because the fixation between antenna array framework and antenna element is certainly existed asks
Topic, so as to be difficult to ensure that between antenna element and antenna array framework that parallelism precision is 0.0.5mm, and passes through vibration test
With the problem of transport test, and when even affecting the problem of low slow little AESA detection radar range accuracy etc. it is all
During many problems, just must using the present invention design projective table type stainless steel special fastening screw and stainless steel it is special install nut come
Guarantee that the quasi-parallel degree of low slow installation between little AESA detection radar antenna array framework and antenna element is 0.05mm.Will

Journey is smoothed out.Now again another stainless steel nut 6 and stainless steel spring pad 5 are screwed into into the projective table type stainless steel special
With on screw 4, with the stainless steel nut tightened above some distances are pulled open.Then further according to laser range finder measurement
The value of making up the difference of the fixing hole, installs stainless steel is special after nut 4 is screwed on value desired position of making up the difference, is surveyed with depth gauge rule
Measure special end face and the antenna array framework for installing nut of the stainless steel make up the difference value and whether provide for laser range finder this is solid
The value of making up the difference in hole is determined, if after having reached the requirement of the value of making up the difference, it is possible to by that stainless steel nut just now, in addition one
Individual stainless steel nut is special with stainless steel to install nut screwing clamping (method of attachment of the assembling mode referring to accompanying drawing 4).Because stainless steel
Special installation nut is by stainless steel spring pad behind and stainless steel nut screwing clamping, now, the special peace of stainless steel
Loading nut is similarly lumped together with projective table type stainless steel special fastening screw, therefore on, no matter antenna element is because of itself
Debugging need or sole mass on go wrong, needs are unloaded or are reinstalled, all without causing antenna element and antenna
There is any change in the value of making up the difference between battle array framework.In a word, using the projective table type stainless steel special fastening screw and not of the present invention
