Description
Technical field
The invention belongs to microwave coaxial transmission line manufacture technology field, in particular a kind of fixture and closing method of realizing the accurate centering closing in of fluting center conductor.
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, require the center conductor size in connector more and more less, required precision is also more and more higher, and the closing in of fluting center conductor and setting process are the key process technology of producing the high-performance fluting center conductor that meets designing requirement, closing in precision, axiality and the out of roundness of closing in conductor directly have influence on the core capabilities index of product.
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 closing in, then part is placed in to equipment for Heating Processing and carries out ageing strengthening sizing.
Except manual closing in mode, also there is in recent years utilizing mould the close up technical scheme of sizing of center conductor of slotting, the cross sectional shape of mould is bellmouth, when closing in, directly fluting center conductor is directly pressed into bellmouth, after utilizing the closing in of inner surface cross-notching center conductor of bellmouth, profile positions setting, carries out afterwards timeliness heat treatment.
The subject matter that manual closing method exists is: center conductor size is less, manual operations trouble, and production efficiency is low; Easily cause hole lobe distortion, product yields is low; Closing in low precision, after closing up, cross section out of roundness and axiality are difficult to ensure; Product quality is affected by people's destabilizing factor to be difficult to there is good consistency, to cause performance index and poor stability.
Existing utilize mould slot center conductor close up sizing technical scheme in, when fluting center conductor is directly pressed into bellmouth, must guarantee that four hole lobes of jack contact just, formation a sealing annular.But in existing scheme, do not have any measure to ensure this effect, ensure equally by operating personnel's experience, in actual production, normal appearance causes part hole lobe excessive to internal strain because being pressed into tension, causes fluting conductor to scrap; Or conductor is pressed into out of plumb and causes contracting eccentric, directly affect connector axiality and out of roundness index; Or fluting conductor is pressed into quantity not sufficient and causes in poor harvestly mouthful, and then cause contact engaging and separating force and connect-disconnect life not to 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, and a kind of fixture and closing method that the accurate centering of fluting center conductor is closed up of realizing is provided.
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, comprise the following 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 treatment shaping;
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, in described step 101, Precision Machining shaping cover and centring means comprise: select metal material to process; Shaping cover and centring means size cooperatively interact, centring means entirety can closely be encased in shaping cover, the final size of internal diameter after conductor closing in centered by centring means outside dimension, the final size of external diameter after conductor closing in centered by the conical lower portion internal diameter size of shaping cover;
Fixture and closing method that the described accurate centering of realization fluting center conductor is closed up, wherein, in described step 102, use the feel relieved method of closing in of shaping cover and centring means cross-notching center conductor to be: centring means and shaping cover are fitted together to formation built-up jig, then steadily pack vertically fluting center conductor into built-up jig, while packing center conductor into, can under the prerequisite of not destroying workpiece, try one's best to strengthen and press-fit dynamics, can not cause hole lobe distortion or eccentric, and be precision centering and closing in state while packing shaping cover conical lower portion into;
Fixture and closing method that the described accurate centering of realization fluting center conductor is closed up, wherein, in described step 103, shaping cover, centring means and fluting center conductor after combination are heat-treated as the three after combination is positioned over and in vacuum heat treatment equipment, carried out 320 degrees Celsius and be incubated the ageing strengthening heat treatment shaping of 2 hours.；
Fixture and closing method that the described accurate centering of realization fluting center conductor is closed up, wherein, in described step 104, the method of taking off shaping cover and centring means is, heat treated assembly is naturally cooled to normal temperature, then part is taken off from built-up jig, built-up jig is reusable.
Adopt such scheme, the technological means that can improve at present open and application is without centering means and lack the present situation of the indicatory device that is press-fit into place, then solve the problem that closing in precision is low, axiality out of roundness is poor and closing in quality conformance is poor that existing method causes, realized centering completes with accurate closing in simultaneously, ensure that closing in precision, out of roundness and axiality meet designing requirement, improve the consistency of closing in quality simultaneously, and enhance productivity, built-up jig apparatus structure is simply easy to produce and can repeatedly reuse, and economic and social benefit is obvious.
