Abstract
The utility model discloses a multi -functional self -locking nut, including nut body (b), (b) is provided with the internal thread at nut body's lower extreme, is provided with the flaring section in nut body's upper end, evenly is provided with the external tooth more than two on nut body's outer wall, is provided with the bellied riveting face that makes progress between adjacent external tooth. The utility model discloses changing the locking structure that traditional self -locking nut is single, having realized the pluralism function of self -locking nut, self -locking nut has possessed locking, flaring simultaneously, has turned over rivets and prevents rotating the function to satisfy different assembly demands, improved assembly efficiency.
Description
Technical field
The utility model relates to a kind of Multifunctional self-locking nut, belongs 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.
Model utility content
The purpose of this utility model is, provides 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 of riveting, rotation inhibiting function, to overcome prior art deficiency.
The technical solution of the utility model: 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.
Further, the outer wall of nut body is evenly provided with 6 external tooths.
Owing to adopting technique scheme, the utility model has the advantage of: the utility model 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 utility model, 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 utility model 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.

Fig. 2 is the A-A sectional view of Fig. 1.
Description of reference numerals: 1-nut body, 2-internal thread, 3-external tooth, 4-rivets face, 5-flared section.
Embodiment
In order to make the utility model object, technological scheme and advantage clearly, below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment of the present utility model: see Fig. 1 and Fig. 2, a kind of Multifunctional self-locking nut of the utility model, comprises nut body 1
,the lower end of nut body 1 is provided with internal thread 2, the upper end of nut body 1 is provided with flared section 5, the outer wall of nut body 1 is evenly provided with 6 external tooths 3, between adjacent external tooth 3, be provided with the riveted joint face 4 raised up, the cross section in described riveted joint face 4 is right-angled triangle thinning gradually from the bottom up.The utility model changes the single locking mechanism of traditional self-locking nut, achieves the pluralistic function of self-locking nut, and a self-locking nut has possessed locking, enlarging simultaneously, turned over riveting and rotation inhibiting function, thus meets different assembling demands, improves efficiency of assembling.
