Abstract
The invention discloses a multifunctional self-locking nut and a manufacturing method thereof. The self-locking nut comprises a nut body, wherein the lower end of the nut body is provided with an internal thread; the upper end of the nut body is provided with a flared section; the outer wall of the nut body is uniformly provided with more than two external teeth; and a riveting surface which bulges upwards is arranged between every two adjacent external teeth. The flared self-locking nut changes the single locking structure of the traditional self-locking nut, implements the diversified functions of the self-locking nut, and has the functions of locking, flaring, rivet turning and rotation prevention, thereby satisfying different assembly demands and enhancing the assembly efficiency.
Description
Technical field
The present invention relates to a kind of Multifunctional self-locking nut and preparation method thereof, belong to standard piece manufacturing technology field.
Background technique
At present, in aerospace field, self-locking nut has played very important role, and the part of nearly more than 40% is all self-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 self-locking nut only has auto-lock function, when Assembly part, sometimes also need self-locking nut have can enlarging, turn over riveting and rotation inhibiting function, to meet different assembling demands.
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, also have while meeting auto-lock function can enlarging, turn over the Multifunctional self-locking nut and preparation method thereof of riveting, rotation inhibiting function, to overcome prior art deficiency.
Technological scheme of the present invention: a kind of Multifunctional self-locking nut, comprises nut body
,the lower end of nut body is provided with internal thread, the upper end of nut body is provided with flared section, the outer wall of nut body is evenly provided with plural external tooth, between adjacent external tooth, be provided with the riveted joint face raised up.
The cross section in aforesaid riveted joint face is triangle or rectangle.
The outer wall of nut body is evenly provided with 6 external tooths.
Simultaneously, the present invention also provides a kind of method making above-mentioned Multifunctional self-locking nut, first the method adopts alloy bar by the profile blank thermal forge-pressing-forming of self-locking nut, then machining is carried out to profile blank, add the lower end machining internal thread of man-hour at nut body, then in the upper end of nut body processing flared section, then on the outer wall of nut body, evenly plural external tooth is processed, and the riveted joint face raised up is made between adjacent external tooth, last internal thread carries out shell nosing treatment, thus make self-locking nut not only have locking function, but also have can enlarging, turn over riveting, rotation inhibiting function.
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 self-locking nut, achieve the pluralistic function of self-locking nut, a self-locking nut has possessed locking, enlarging simultaneously, has turned over riveting and rotation inhibiting function, thus meet different assembling demands, improve efficiency of assembling.In addition, the disposable machine shaping of self-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, the present invention not only structure is simple, easy to assembly, cost is low, quality is light, intensity is high, and stable mechanical performance, easy to maintenance, and the relative positional accuracy between being specially adapted to two links requires higher assembly connection.
