Description

A kind of fixture and closing method of realizing the accurate centering closing in of fluting center conductor
Technical field
The invention belongs to microwave coaxial transmission line manufacture technology field, in particular a kind of realization openedFixture and closing method that the accurate centering of groove center conductor is closed up.
Background technology
The center conductor of microwave signal transmission channel is generally divided into a sun center conductor and a cloudy center conductor(center conductor of slotting), along with the development of technology, frequency test signal improves constantly, requirementCenter conductor size in connector is more and more less, and required precision is also more and more higher, and fluting central guidingThe closing in of body and setting process are the crucial works of producing the high-performance fluting center conductor that meets designing requirementTechnology, closing in precision, axiality and the out of roundness of closing in conductor directly has influence on the core of productCan index.
The bottling technique of the cloudy center conductor of existing fluting, what mostly adopt is the manual mode closing up,To be operating personnel directly act on fluting center conductor with the instrument such as tweezers, steel wire makes its distortion reach receiptsMouthful, then part is placed in to Equipment for Heating Processing and carries out ageing strengthening sizing.
Except manual closing in mode, also occurred in recent years utilizing mould slot center conductor close upThe technical scheme of sizing, the cross sectional shape of mould is bellmouth, the center conductor of directly slotting when closing inDirectly be pressed into bellmouth, utilize the closing in of inner surface cross-notching center conductor of bellmouth after profile carry outLocation setting, carries out timeliness heat treatment afterwards.
The subject matter that manual closing method exists is: center conductor size is less, manual operations trouble,Production efficiency is low; Easily cause hole lobe distortion, product yields is low; Closing in low precision, cross section after closing upOut of roundness and axiality are difficult to ensure; It is good that product quality is affected by people's destabilizing factor to be difficult to haveUniformity, causes performance indications and poor stability.
Existing utilize mould slot center conductor close up sizing technical scheme in, in slottingWhen being directly pressed into bellmouth, must guarantee heart conductor that four hole lobes of jack contact just, form a sealingAnnular. But in existing scheme, there is not any measure to ensure this effect, equally by operatorMember's experience ensures, often occurs causing part hole lobe to internal strain because being pressed into tension in actual productionDegree, causes fluting conductor to scrap; Or conductor is pressed into out of plumb and causes contracting eccentric, directly impact connectsDevice axiality and out of roundness index; Or fluting conductor is pressed into quantity not sufficient and causes in poor harvestly mouthful, and then cause insertingPull out force and connect-disconnect life can not meet design requirement.
Therefore, there is defect in prior art, needs to improve.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, provides a kind of realization to openFixture and closing method that the accurate centering of groove center conductor is closed up.
Technical scheme of the present invention is as follows:
Realize fixture and a closing method that the accurate centering of fluting center conductor is closed up, wherein, compriseFollowing steps:
Step 101: Precision Machining shaping cover and centring means;
Step 102: use the closing in of feeling relieved of shaping cover and centring means cross-notching center conductor;
Step 103: shaping cover, centring means and fluting center conductor after combination are carried out to timeliness heat placeReason sizing;
Step 104: take off shaping cover and centring means, obtain final part.
Fixture and closing method that the described accurate centering of realization fluting center conductor is closed up, wherein, instituteState in step 101, Precision Machining shaping cover and centring means comprise: select metal material to process;Shaping cover and centring means size cooperatively interact, and centring means entirety can closely be encased in sizingIn cover, the final size of internal diameter after conductor closing in centered by centring means outside dimension, the cone of shaping coverThe final size of external diameter after conductor closing in centered by the internal diameter size of shape bottom;
Fixture and closing method that the described accurate centering of realization fluting center conductor is closed up, wherein, instituteState in step 102, use the feel relieved side of closing in of shaping cover and centring means cross-notching center conductorMethod is: centring means and shaping cover are fitted together to formation built-up jig, the central guiding of then slottingBody steadily packs built-up jig vertically into, while packing center conductor into, can not destroy under the prerequisite of workpieceAs far as possible strengthen and press-fit dynamics, can not cause hole lobe distortion or eccentric, and while packing shaping cover conical lower portion intoBe precision centering and closing in state;
Fixture and closing method that the described accurate centering of realization fluting center conductor is closed up, wherein, instituteState in step 103, shaping cover, centring means and fluting center conductor after combination are heat-treatedFor being positioned over, the three after combination in vacuum heat treatment equipment, carries out 320 degrees Celsius and be incubated 2 hoursAgeing strengthening heat treatment shaping. ;
Fixture and closing method that the described accurate centering of realization fluting center conductor is closed up, wherein, instituteState in step 104, the method for taking off shaping cover and centring means is that heat treated assembly is enteredRow naturally cools to normal temperature, then part is taken off from built-up jig, and built-up jig is reusable.
Adopt such scheme, the technological means that can improve at present open and application without centering means andLack the present situation of indicatory device of being press-fit into place, then solve the closing in precision that existing method causes low, withThe problem that axle degree out of roundness is poor and closing in quality conformance is poor, has realized centering and accurate closing in simultaneouslyComplete, ensured that closing in precision, out of roundness and axiality meet designing requirement, improve closing in matter simultaneouslyThe uniformity of amount, and enhance productivity, built-up jig apparatus structure is simply easy to produce and can be repeatedlyRecycling, economic and social benefit is obvious.
