The quasi- manufacturing procedures such as prefabricated use, wherein the machining tool of conical antenna cover outer surface is to have numerical control grinding power device
Numerically controlled lathe, support frame 40 are outer round buss.It, first will cone when needing the inner surface to tapered radome to be clamped positioning
Shape locating piece 11 ' fills in spindle of numerical control lathe hole, is that identical cone angle is fitted close between taper locating piece 11 ' and spindle hole, and hundred
The interior circle pulsation for dividing table to examine taper locating piece 11 ' is less than 0.03mm.
Then will tool there are four adjust first group of adjusting fixed part of fixed part 30, adjust the of fixed part 30 with eight
Two groups of adjusting fixed parts are circumferential uniformly to pass through chuck clamping in numerically controlled lathe on outer round buss, then by outer round buss
On, outside diameter runout is less than 0.10mm, and first group of adjusting fixed part, second group of adjusting fixed part are tuned appropriate outer diameter.
Then, by feeding mechanism that tapered radome 100 is slow along machine axes direction from first end to second end
It is sent into outer round buss, keeps the cone-shaped inner hole 111 ' of the outer surface and taper locating piece 11 ' at the first end of tapered radome 100 tight
Close fit.By second group of adjusting fixed part radiai adjustment, centering, the second end of tapered radome 100 is clamped, then tightens first
Group is adjusted fixed part and is supported with the hanging section in centre to tapered radome 100, and 100 second end appearance of tapered radome is passed through
Face, inner surface carry out tapered radome centering, and the roughing process centering of tapered radome 100 requires circle bounce to be less than 0.1mm,
Finishing step centering requires circle bounce to be less than 0.05mm.Wherein, in the arc compression block and tapered radome for adjusting fixed part
The contact site of outer surface is provided with silicone rubber pad.
Finally by the end face patch at the second end of two baffles and tapered radome that are arranged on outer round buss end face
It closes to limit the movement of tapered radome 100 in axial direction.
In addition, as other embodiments of the invention, it is possible to use the positioning for tapered radome of the invention clamps
Device uses to carry out antenna house big end surplus excision manufacturing procedure.It is used for antenna house big end surplus excision manufacturing procedure
Positioning clamping device is similar with the positioning clamping device used for antenna cover inner surface manufacturing procedure, it is only necessary to by the second positioning
Portion's removal can be used to the manufacturing procedure of antenna house big end surplus excision.
In conclusion the positioning clamping device provided by the present invention for tapered radome is mechanical overall structure,
The first end self-centering of tapered radome is enabled to by cooperating with spindle of numerical control lathe hole, then uses adjusting screw rod and arc
The connection of shape briquetting, arc compression block moves closer to the outer surface of tapered radome with the rotation of adjusting screw rod, when arc compression block and
After antenna house external form face contact, keep in-plane static, but adjusting screw rod may continue to tune and hold out against arc compression block and fix
Tapered radome dexterously converts the tilting force of adjusting screw rod to the normal force of conical antenna cover outer surface, tapered radome
Second end can be tightly fastened.Such mode can make tapered radome axis and number by both ends circularity direction centering
It is consistent to control turning center line, the tapered radome wall thickness that processes, concentricity can meet technical requirement.
When carrying out the processing of quartzy wave transparent ceramic radome using positioning clamping device of the invention, the entire process-cycle
It is related to outer surface Roughing and fine machining, the totally four process clamping conversions of inner surface Roughing and fine machining, positioning clamping device of the invention
Installation way do not changed by tapered radome outer dimension, configuration of surface and influenced, can be used for tapered radome entire plus
Work process can not only carry out the roughing of coarse tapered radome blank, but also can carry out the finishing of smooth finish surface tapered radome,
It is convenient to setting length direction, diametrical direction processing technology benchmark.Such installation way can be by changing tooling size
To realize the processing of different sizes tapered radome.
In addition, positioning clamping device of the invention all realizes that structure type is succinct, solves existing by mechanical structure
The technical issues of technology is difficult to through vacuum suction mode Set and Positioning to high air penetrability quartz pottery antenna covering, it is easy to operate,
It is reliable and stable, it is more suitable for actual production, all process steps conversion clamping can effectively be controlled by control circle bounce centering
Surfaces externally and internally concentricity guarantees the final processing quality of tapered radome to achieve the purpose that control wave transparent area wall thickness accuracy.
