Description
Technical field
The invention belongs to antenna manufacture fields, and in particular to a kind of target seeker slot array antenna processing method.
Background technology
Common hyperfrequency is generally adopted by slot array antenna etc. with transmitting antenna.And the guiding cephalic slit used in guided missile
Array antenna is to play the role of hyperfrequency transmitting antenna in guided missile with the huge array antenna of crack gap quantity,
Such way often not only improves in a limited space, improves the precision of missile homer guidance, also can be to the maximum extent
The transmission power of target seeker itself radar is reduced, meanwhile, also reduce the production cost of guided missile.
Target seeker slot array antenna is often on the rust-preventing aluminum alloy plate of 0.5mm left and right thicknesses, using High Speed Milling Operation
Cut the method for processing formed target seeker slot array antenna form hole structure.And this microwave device is to target seeker crack
Structure width, the length in the hole in array antenna crack gap have stringent requirement on machining accuracy.The crack of target seeker in this example
Array antenna machining accuracy is the length in crack gap：The width in crack gap is：And in this example
Slot array antenna crack gap quantity be 2484.
To the processing of target seeker slot array antenna, there are two kinds at present：
Conventional method one：0.5mmX180mmX180mm aluminum alloy materials are directly fastened on supporting tool plate by pressing plate
Upper carry out Milling Process.This method major defect has：Since overall deformation area is big in milling process for aluminum alloy materials, and it is somebody's turn to do
Use is used in processingHard alloy milling cutter, diameter is small, poor rigidity, it is easy to because part becomes
Cutting output caused by shape increases and generating breaking phenomenon causes part rejection, increase the process-cycle, increase processing cost.Because of fixation
It is ineffective, cause in process can blank will produce vibration, finished product roughness increasing out, milling amount it is unbalanced,
Milling stage property is caused to easily snap off.
Conventional method two：0.5mmX180mmX180mm aluminum alloy materials are adsorbed on vacuum cup and carry out Milling Process.
This method major defect has：Since work in-process will use vacuum cup and compressed air pump so that Productive statistics greatly improve,
Increase entreprise cost；It is existing in order not to allow vacuum cup that " leakage is inhaled " occurs and when carrying out Milling Process gap on vacuum cup
As gap cannot mill through, and can form surplus material in part lower part in this way, be not easy to ensure the consistency of gap or more size, right
Postorder processing makes a big impact, and increases workload, increases the process-cycle.

Step 3：Area restriction tooling is installed in the circular hole in clamping tool, the area limits tooling as φ
The 3/4 of 150mm is round, and the center of circle and the circular hole center of circle in clamping tool of area restriction tooling are concentric；Area limits tooling and uses
Pressing plate is fixed, and according to the position of four quadrants, uses φ 0.3mm carbide-tipped milling cutters, 30000 revs/min of rotating speed of setting, feeding speed
Spend 150mm/ points, cutting depth 0.03mm, 2484 crack of milling；
Step 4：It unloads area and limits tooling, contour milling tooling is positioned in the circular hole in clamping tool, pressure is used
Plate is fixed, then unloads clamping tool, and the contour milling tooling is the circle that thickness is 5mm, φ 150mm；Use φ 4mm hard
Alloy milling cutter, 24000 revs/min of rotating speed of setting, 1500mm/ points of feed speed, cutting depth 0.2mm, along contour milling tooling
Milling shape obtains target seeker slot array antenna.
Advantageous effect
A kind of target seeker slot array antenna processing method proposed by the present invention, it is exactly more complicated by what is used originally
Processing becomes the processing for being easy to common operator progress, directly reduces the requirement to the processing technology technical ability of operator, be convenient for
The target seeker slot array antenna of batch production processing millimeter wave missile-borne radar.It is fundamentally solved used such originally
The processing of the target seeker slot array antenna of type millimeter wave missile-borne radar, in the target seeker crack of the type millimeter wave missile-borne radar
When in the process of array antenna, often because original processing select it is unreasonable so that operator is difficult to ensure target seeker crack
The machining accuracy and process quality issue in the crack gap of array antenna.And processing sequence using the present invention, it is finally reached
The quality objective that the target seeker slot array antenna passing rate of processing of millimeter wave missile-borne radar is 100%, while single millimeter wave
The target seeker slot array antenna of missile-borne radar just saves machining period 1 hour or more, both improved millimeter wave missile-borne radar it
The processing efficiency of target seeker slot array antenna also synchronizes the target seeker slot array day for substantially increasing millimeter wave missile-borne radar
The passing rate of processing of line.Therefore it on, improves its detection accuracy for millimeter wave missile-borne radar and detection range provides beneficial branch
It holds.And because of processing technology scheme using the present invention, it has been finally reached the use difficulty and drop for reducing user to the maximum extent
The low purpose for making expense.
Processing technology scheme using the present invention, fundamentally solve it is original that be both difficult to ensure the type millimeter wave
The machining accuracy and surface roughness of the target seeker slot array antenna of missile-borne radar；It is difficult to ensure processing the type millimeter wave again
The quality objective of the qualification rate 100% of the target seeker slot array antenna of missile-borne radar, meanwhile, in its whole process also
Because process quality issue causes the inferior problems of low production efficiency, and the guiding of millimeter wave missile-borne radar is completed well
Cephalic slit array antenna high-precision and efficient processing.
