Abstract
The utility model discloses a kind of cold-heading integral type resonant rod, is integral type cold-heading part, includes main part and interconnecting piece；The upper surface of the main part is recessed to be formed with cavity, and the bottom surface of the cavity is recessed to be formed with interior hexagonal plum blossom connected in star, and radially expanded extend of the upper surface periphery of main part has an annular slab；The interconnecting piece integrally extends downwardly out in main part lower end surface is central axial.This product is integral type cold-heading part, have the advantages that production is high in machining efficiency, materials save, is at low cost, deformation is big, stability is high, and precision is high, interior hexagonal plum blossom connected in star is formed with the bottom surface of cavity is recessed simultaneously, without other drivescrew, further shorten the production period, also further reduces the cost.
Description
Technical field
The utility model relates to resonant rod field technologies, refer in particular to a kind of cold-heading integral type resonant rod.
Background technique
Resonant rod is used in necessary part on space flight broadcasting and TV communication base station equipment.Also known as oscillator, reflective spindle, harmonic oscillator,
Resonant column etc..Currently, the resonant rod produced in filter industry is largely formed by Vehicle Processing, due to Vehicle Processing resonant rod
It is the serious waste of material not only to be easy to cause by raw material cutting forming, but also the rate for manufacturing steel part is slow, tool damage is tight
Weight, to considerably increase manufacturing cost；Also, current resonant rod all has a cavity, in order to reach the mesh of debugging signal
, it is required to that plum blossom trough is arranged in cavity, existing way mainly squeezes into a screw in cavity, utilizes the screw itself
On plum blossom trough constitute the plum blossom trough in inner cavity, it is so inevitable since first the vehicle in cavity goes out screw hole for the needs of squeezing into of screw
It will lead to the extension in production period, while also increasing cost.Therefore, it is necessary to be improved to current resonant rod.
Utility model content
In view of this, the utility model is in view of the existing deficiencies of the prior art, main purpose is to provide a kind of cold-heading one
Body formula resonant rod can effectively solve the problem of existing resonance rod structure makes the production period long and increases cost.
To achieve the above object, the utility model is using following technical solution:
A kind of cold-heading integral type resonant rod is integral type cold-heading part, includes main part and interconnecting piece；The main part
Upper surface it is recessed be formed with cavity, the bottom surface of the cavity is recessed to be formed with interior hexagonal plum blossom connected in star, the upper surface of main part
Radially expanded extend of periphery has an annular slab；The interconnecting piece integrally extends downwardly out in main part lower end surface is central axial.
As a preferred embodiment, the open edge outer circle corner structure of the cavity.
As a preferred embodiment, the plum blossom trough phase of the interior hexagonal plum blossom connected in star and the soket head cap screw of T8 model
Together, depth 1.2-1.6mm.
As a preferred embodiment, the interconnecting piece is cylindrical body, and outer surface is formed with external screw thread.
The utility model has clear advantage and beneficial effect compared with prior art, specifically, by above-mentioned technology
Known to scheme:
This product is integral type cold-heading part, and with making, high in machining efficiency, materials are saved, at low cost, deformation is big, stability height
The advantages of, and precision is high, while being formed with interior hexagonal plum blossom connected in star the bottom surface of cavity is recessed, without in addition squeezing into spiral shell
Nail further shortens the production period, also further reduces the cost.
For the structure feature and effect for more clearly illustrating the utility model, come with reference to the accompanying drawing with specific embodiment pair
The utility model is described in detail.
Detailed description of the invention
Fig. 1 is the top view of the preferred embodiment of the utility model；
Fig. 2 is the bottom view of the preferred embodiment of the utility model；
Fig. 3 is the sectional view of the preferred embodiment of the utility model.
Description of drawing identification:
10, main part 11, cavity
12, interior hexagonal plum blossom connected in star 13, annular slab
20, interconnecting piece 21, external screw thread.
Specific embodiment
It please refers to shown in Fig. 1 to Fig. 3, it to be one that show the specific structures of the preferred embodiment of the utility model
Body formula cold-heading part includes main part 10 and interconnecting piece 20.
The upper surface of the main part 10 is recessed to be formed with cavity 11, and the bottom surface of the cavity 11 is recessed to be formed with interior hexagonal plum blossom
Connected in star 12, radially expanded extend of the upper surface periphery of main part 10 have an annular slab 13；In the present embodiment, the main part
10 be cylindrical tube, and the outer diameter of main part 10 is 4.95-5.05mm, and the length of main part 10 is 6.95-7.05mm, the cavity
11 open edge outer circle corner structure, the depth of cavity 11 are 4.5mm.Within the interior hexagonal plum blossom connected in star 12 and T8 model
The plum blossom trough of hex screw is identical, depth 1.2-1.6mm, and the outer diameter of the annular slab 13 is 7.5-7.6mm, annular slab 13
With a thickness of 1mm.
The interconnecting piece 20 integrally extends downwardly out in 10 lower end surface of main part is central axial, and the interconnecting piece 20 is cylinder
Body, outer surface are formed with external screw thread 21, and the length of the interconnecting piece 20 is 4.5mm, and the axial length of external screw thread 21 is 4mm.
The design focal point of the utility model is: this product is integral type cold-heading part, has and makes high in machining efficiency, materials
It saves, is at low cost, the advantage that deformation is big, stability is high, and precision is high, while being formed with interior hexagonal plum the bottom surface of cavity is recessed
Flower-shape groove is not necessarily to other drivescrew, further shortens the production period, also further reduce the cost.
The above descriptions are merely preferred embodiments of the present invention, not makees to the technical scope of the utility model
Any restrictions, therefore any trickle amendment made by the above technical examples according to the technical essence of the present invention, equivalent change
Change and modify, is still within the scope of the technical solutions of the present invention.
