Abstract
A double-lug spherical multifunctional hi-lock nut comprises a large nut body, a large thread, a large broken-neck groove, a hexahedron, a large nut body spherical surface and a large spherical washer. The hi-lock nut further comprises a small nut body arranged in a small thread, wherein a small nut body spherical surface is arranged on the small nut body, a small spherical washer is arranged on the small nut body spherical surface, and a small broken-neck groove is formed between the hexahedron and the small nut body. According to the double-lug spherical multifunctional hi-lock nut, an external form blank is formed through direct hot forging pressing of a bar, material utilization rate is increased, the modern less-cutting or no-cutting development trend is met, multiple functions of the hi-lock nut are realized, and two hi-lock nut parts in different specifications are obtained through separation after one hi-lock nut is machined and assembled; furthermore, free rotation is achieved through the interaction between the nut bodies and the spherical washers, so that cost is reduced, material utilization rate is effectively controlled, safety and reliability are high, mechanical performance is stable, and maintenance is convenient. The double-lug spherical multifunctional hi-lock nut is especially suitable for assembly connection with high requirement for precision of relative positions of two connectors.
Description
Technical field
The present invention relates to a kind of ears and seal multi-functional Closely locking nut, belong to fastening piece processing technique field.
Technical background
When in aerospace field, two parts connect at present, self-locking nut has played very important role, the part of nearly more than 40% is all Closely locking nut aboard, in the progressively powerful country of industrial system today, development of new technology on some part, accomplish that a part can have multiple function simultaneously, so not only save cost of production, also effectively control weight.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of Closely locking nut, possesses several functions simultaneously, to solve such product material effective rate of utilization, stability etc. of enhancing product performance.
For solving the problems of the technologies described above, the present invention adopts following technological scheme:
The multi-functional Closely locking nut of a kind of ears sphere, comprises big nut body 1, major thread 2, large cut-off neck slot 3, hexahedron 4, big nut body sphere 10 and large spherical washer 11; This Closely locking nut also includes the primary nut body 7 be located in minor thread 6, and primary nut body 7 offers primary nut body sphere 9, and primary nut body sphere 9 is provided with small sphere of exterior rearview packing ring 8, offers a little cut-off neck slot 5 between hexahedron 4 and primary nut body 7.
The described multi-functional Closely locking nut of ears sphere, adopt plasticity good, metal grain does not rupture after die-forging forming, and crystal grain, along its length in the direct thermal forge-pressing-forming blank of metal bar of the linear alignment, is processed into through machinery is disposable.
The described multi-functional Closely locking nut of ears sphere, application shape memory alloy, at high temperature compression molding cools rapidly, obtains arbitrary shape blank.
Adopt the beneficial effect of technique scheme:
Compared with prior art, the present invention's application bar direct thermal forge-pressing-forming profile blank, improves stock utilization, meets modern few cutting or the development trend without cutting.
The present invention changes the single locking mechanism of traditional Closely locking nut, achieve the pluralistic function of Closely locking nut, process this Closely locking nut, isolate the Closely locking nut of two pieces sample diversified in specifications after assembling, and the interaction of nut body and spherical washer reaches free rotating effect simultaneously, which save cost, effectively control stock utilization, safety reliability is high, stable mechanical performance, easy to maintenance, the relative positional accuracy between being specially adapted to two links requires higher assembly connection.

Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail, but not as any limitation of the invention.
The multi-functional Closely locking nut of a kind of ears sphere, as shown in Figure 3, by receiving pressure major thread 2 and produce local deformation by receiving pressure minor thread 6 on primary nut body 7 on big nut body 1, makes this Closely locking nut be provided with locking function.
Product of the present invention, when assembling, reaches free rotating function by big nut body sphere 10 and the interaction of large spherical washer 11, and same principle primary nut body sphere 9 and small sphere of exterior rearview packing ring 8 also can reach and freely rotate effect, can meet seal request again simultaneously.
Product of the present invention is disposable to be machined, big nut body 1 and the primary nut body 7 of sample diversified in specifications is distributed with at hexahedron 4 two ends, by effectively controlling the large cut-off neck slot 3 at hexahedron 4 two ends, little cut-off neck slot 5 size meets each performance index such as effective assembling moment, save time material-saving, Product Precision is higher, consistency of performance is better, thus meet the performance requirement of this Closely locking nut, under during assembling, hexahedron 4 is the effect of twisting sleeve, a Closely locking nut isolates big nut body 1 and primary nut body 7 simultaneously, thus change product single structure, effectively control product effective rate of utilization.
Described big nut body 1 and primary nut body 7 screw thread present ladder pattern distribution, and (screw thread specification is not identical, as: one end M6, the other end M5), when assembling, twisting sleeve and hexahedron 4 produce active force like this, first screw thread departs from hexahedron 4 compared with the little cut-off neck slot 5 at small end place, then repeat above-mentioned steps, the large cut-off neck slot 3 at larger end place also departs from hexahedron 4, thus achieves and on a part, adjust different mounting torque isolate big nut body 1 and primary nut body 7 simultaneously.
The present invention adopts plasticity good, and metal grain does not rupture after die-forging forming, and crystal grain, along its length in the direct thermal forge-pressing-forming blank of metal bar of the linear alignment, is processed into through machinery is disposable; Its theoretical foundation adopts advanced hitech materials, intensity and the plasticity of material are fabulous, its crystal grain after mold pressing or forging forming not tear type be streamline shape, the i.e. even full height orientation of grain flow line, material greatly strengthens its tensile strength and fatigue strength after mold pressing or forging forming produce flow harden, also can apply shape memory alloy, at high temperature compression molding cools rapidly, obtains arbitrary shape blank.
