Description
Technical field
The invention belongs to microwave coaxial transmission line manufacture technology field, in particular a kind of two groove center conductor precision centering closing in fixtures.
Background technology
The center conductor of microwave signal transmission path is generally divided into positive head center conductor and cloudy head center conductor (center conductor of namely slotting), along with the development of technology, frequency test signal improves constantly, require that the center conductor dimensions in connector is more and more less, required precision is also more and more higher, in design have employed the design that center conductor opens two grooves more, and the closing in of two groove center conductors and setting process are the key technologies realizing high performance center conductor, the closing in precision of conductor, axiality and symmetry directly have influence on the core capabilities index of product.
The bottling technique of the cloudy head center conductor of existing two grooves, most employing be the manual mode closed up, namely operating personnel directly act on two groove center conductors with the instrument such as tweezers, steel wire and make it be out of shape to reach closing in, then part is placed in equipment for Heating Processing and carries out ageing strengthening sizing.
The existing mould that utilizes carries out slotting in the technical scheme of center conductor closing in sizing, fluting center conductor is directly pressed into bellmouth operation.But existing scheme to two groove center conductors close up sizing and inapplicable, because the shape that the cloudy head center conductor cross-sectional shape of two grooves after closing up and hole lobe surround not is regular figure, both be different from circle and be also different from ellipse, therefore how to realize closing up to the centering of the cloudy head center conductor of two grooves, existing scheme bellmouth mould just seems helpless, centering can not be ensured, can not have closing in profile and shape accurately.
Therefore, prior art existing defects, 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 two groove center conductor precision centering closing in fixtures.
Technical scheme of the present invention is as follows:
A kind of two groove center conductor precision centering closing in fixtures, wherein, offer sizing closing in groove, described sizing closing in trench bottom center are provided with centring elements in the side of a cuboid mould; The prearranged multiple of the front diameter of conductor closing in centered by the width of described cuboid mould.
Described centering closing in fixture, wherein, described sizing closing in groove is a ladder-type trough, and the open-topped length of described ladder-type trough is greater than the length bottom described ladder-type trough.
Described centering closing in fixture, wherein, described sizing closing in groove and described centring elements are wholely set.
Described centering closing in fixture, wherein, described prearranged multiple is 3-10 times.
Described centering closing in fixture, wherein, the open-topped length of described ladder-type trough is more than or equal to the front diameter of center conductor closing in.
Described centering closing in fixture, wherein, the length bottom described ladder-type trough is equal with center conductor closing in rear end face final size.
Described centering closing in fixture, wherein, the groove width after the width dimensions of described centring elements finally closes up with center conductor is equal, and be less than center conductor close up before groove width.
Described centering closing in fixture, wherein, described centring elements top is circular arc, for preventing the damage of cross-notching in closing in process.
Adopt such scheme, technology that is open and application at present of can improving lacks irregular closing in shape centering ability, and the present situation of control cannot be realized to size and dimension, then the two groove center conductor closing in precision that existing method causes are solved low, the problem of axiality symmetry difference and closing in quality conformance difference, achieve two groove center conductor centering to complete with accurate closing in simultaneously, ensure that closing in precision, designing requirement is met with axiality, improve the consistency of closing in quality simultaneously, and enhance productivity, built-up jig apparatus structure is simple, be easy to produce and can repeatedly reuse, economic and social benefit is obvious.
