A first nut body and a second nut body are arranged at the two ends of a hexahedron of the high-locking nut respectively; a first breaking-neck groove and a second breaking-neck groove are designed in connecting positions of the hexahedron with the first nut body and the second nut body respectively; the thread specification of a first screw thread in the first nut body is different from that of a second screw thread in the second nut body; the size of the first breaking-neck groove is also different from that of the second breaking-neck groove. By means of the multi-functional two-lug high-locking nut and the fabrication method thereof, single locking structures of traditional high-locking nuts are changed; different mounting torques can be adjusted on one part by the high-locking nut, and meanwhile, two parts with different specifications of the high-locking nut can be separated; the position accuracy during assembly can be guaranteed, moreover, the material utilization rate is increased, cost is reduced, and the mass of the high-locking nut is reduced.
Description
Technical field
The present invention relates to multi-functional Closely locking nut of a kind of ears and preparation method thereof, belong to standard piece manufacturing technology field.
Background technique
At present, in aerospace field, Closely locking nut has played very important role, and the part of nearly more than 40% is all Closely locking nut aboard.In the progressively powerful country of industrial system today, development new technologies on some part, accomplish that a part can have multiple function simultaneously, have so not only saved cost of production, also effectively controlled weight.But, existing Closely locking nut is all the single locking mechanism be made up of a hexahedron and a nut body, when assembling two parts on same axis, need to use two Closely locking nuts, meanwhile, because position accuracy demand is higher simultaneously, also need after having assembled to carry out position correction, this not only adds the weight of Closely locking nut, and cause efficiency of assembling lower, the demand for development of modern technical aeronautics cannot be met.
Summary of the invention
The object of the invention is to, provide that a kind of structure is simple, cost is low, quality is light, intensity is high, and multi-functional Closely locking nut of the ears of rigging position precision and preparation method thereof can be ensured, to overcome prior art deficiency.
Technological scheme of the present invention: the multi-functional Closely locking nut of a kind of ears, it is respectively arranged with the first nut body and the second nut body at the two ends of hexahedron, the first cut-off neck slot and the second cut-off neck slot is respectively arranged with in the joint of hexahedron and the first nut body and the second nut body, the first screw thread in the first nut body is not identical with the screw thread specification of the second screw thread in the second nut body, and the first cut-off neck slot is not identical with the size of the second cut-off neck slot yet.
Described hexahedron and the first nut body and the second nut body concentric.
The first described nut body and the second nut body, through shell nosing treatment, make the first screw thread and the second screw thread have the distortion of local.
Simultaneously, the present invention also provides a kind of method making the multi-functional Closely locking nut of above-mentioned ears, first adopt alloy bar by the profile blank thermal forge-pressing-forming of Closely locking nut, then machining is carried out to profile blank, add and produce the first different nut body of screw thread specification and the second nut body respectively at the two ends of hexahedron man-hour, and the first different cut-off neck slot of two sizes and the second cut-off neck slot is offered respectively in the joint of hexahedron and the first nut body and the second nut body, thus achieve and on a part, adjust different mounting torque isolate two pieces nut body simultaneously.
Described alloy bar comprises refractory alloy, titanium alloy, structural carbon steel, alloyed steel, Cuprum alloy and aluminum alloy bar.
Described refractory alloy comprises GH2132, GH4169, GH738, GH4698, GH2696 and GH30 bar; Titanium alloy comprises TC4 and TC16 bar; Structural carbon steel comprises ML35 and ML25 bar; Alloyed steel comprises 30CrMnSiA and 40CrNiMoA bar; Cuprum alloy comprises H62 bar; Aluminum alloy comprises 2A11 and 2A12 bar.
Owing to adopting technique scheme, the invention has the advantages that: the present invention changes the single locking mechanism of traditional Closely locking nut, achieve while Closely locking nut adjusts different mounting torque on a part, isolate the Closely locking nut of two pieces sample diversified in specifications, not only ensure that positional accuracy during assembling, and improve stock utilization, and cost-saving, alleviate the quality of Closely locking nut.In addition, the disposable machine shaping of Closely locking nut employing thermal forge-pressing-forming blank of the present invention, improves stock utilization, and meet modern few cutting or the development trend without cutting, and plasticity is good, metal grain does not rupture after die-forging forming.Therefore, not only structure is simple, easy to assembly, cost is low, quality is light, intensity is high in the present invention, and rigging position precision can be ensured, stable mechanical performance, easy to maintenance, the relative positional accuracy between being specially adapted to two links requires higher assembly connection.

Embodiment
In order to make the object of the invention, technological scheme and advantage clearly, below in conjunction with drawings and Examples, the present invention is described in further detail.
Embodiments of the invention: see Fig. 1, the multi-functional Closely locking nut of a kind of ears of the present invention, it is respectively arranged with the first nut body 1 and the second nut body 7, and hexahedron 4 and the first nut body 1 and the second nut body 7 concentric; The first cut-off neck slot 3 and the second cut-off neck slot 5 is respectively arranged with in the joint of hexahedron 4 and the first nut body 1 and the second nut body 7, the screw thread specification of the first screw thread 2 in the first described nut body 1 is M5, and the screw thread specification of the second screw thread 6 in the second nut body 7 is M6; The length of the first described cut-off neck slot 3 is 1.1mm, the degree of depth is 0.3mm, and the second cut-off neck slot 5 length is 1.3mm, the degree of depth is 0.5mm.The first described nut body 1 and the second nut body 7, through shell nosing treatment, make the first screw thread 2 and the second screw thread 6 have the distortion of local, thus make the first nut body 1 and the second nut body 7 have locking function.
Simultaneously, the present invention also provides a kind of method making the multi-functional Closely locking nut of above-mentioned ears, first adopt alloy bar by the profile blank thermal forge-pressing-forming of Closely locking nut, then machining is carried out to profile blank, add and produce the first nut body 1 that screw thread specification is M5 man-hour respectively at the two ends of hexahedron 4 and screw thread specification is M6 second nut body 7, and to offer a length respectively in the joint of hexahedron 4 and the first nut body 1 and the second nut body 7 be 1.1mm, the degree of depth is 0.3mm be the first cut-off neck slot 3 and a length is 1.3mm, the degree of depth is second cut-off neck slot 5 of 0.5mm, because the size of two cut-off neck slots is different, its moment size of twisting into two parts is not identical yet.Therefore, during twisting hexahedron 4, as shown in Figure 2, second nut body 7 is first separated from the second cut-off neck slot 5 with hexahedron 4, after continuing hexahedron 4, as shown in Figure 3, the first nut body 1 is finally separated from the first cut-off neck slot 3 with hexahedron 4, thus achieves and on a part, adjust different mounting torque isolate two pieces nut body simultaneously.Described alloy bar adopts 2A11 and 2A12 aluminum alloy bar, and the Closely locking nut of aluminum alloy not only has the advantage that material is comparatively light, plastic deformation is good.
