Abstract
The utility model discloses a sealed self -locking nut, this self -locking nut constitutes with the antiskid section by pulling wrong section, is provided with the screw hole in pulling wrong section, has offered the notch on pulling the outer wall of twisting every side of section, the notch have local deformation through close up handling, set up the annular knurl tooth on the outer wall of antiskid section, be provided with in the antiskid section and the screw hole intercommunication join in marriage the dress hole, adorn the downthehole sealing washer of installing joining in marriage, and the sealing washer outer end is higher than the nut body bottom surface. The utility model discloses change the locking structure that traditional self -locking nut is single, realized the pluralism function of self -locking nut, the function that the self -locking nut has possessed locking, has sealed, has alleviateed and prevented to skid simultaneously to satisfy different assembly demands, improved assembly efficiency.
Description
Technical field
The utility model relates to a kind of sealed type 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 to have sealing, alleviate and the function of anti-slip, 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 seals, alleviates and the sealed type self-locking nut of function of anti-slip, to overcome prior art deficiency while meeting auto-lock function.
The technical solution of the utility model: a kind of sealed type self-locking nut, it is made up of twisting section and anti-slip section, in twisting section, be provided with tapped hole, the outer wall of each side of twisting section offers notch, described notch has the distortion of local by shell nosing treatment; The outer wall of anti-slip section arranges annular knurl tooth, in anti-slip section, be provided with the equipped hole be communicated with tapped hole, in equipped hole, seal ring be installed, and seal ring outer end is higher than nut body bottom surface.
Described twisting section is hexagonal, 12 jiaos or ten hexagonal cube structures.
Described seal ring outer end 0.5 ~ 1.5mm higher than nut body bottom surface.
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, self-locking nut possessed locking simultaneously, seal, alleviate and the function of anti-slip, 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.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
Description of reference numerals: 1-notch, 2-tapped hole, 3-annular knurl tooth, 4-seal ring, 5-is equipped with hole, 6-flared section, 7-twisting section, 8-anti-slip 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 sealed type self-locking nut of the utility model, it is made up of the twisting section 7 of hexagonal cube structure and anti-slip section 8, in twisting section 7, be provided with tapped hole 2, the outer wall of each side of twisting section 7 offers notch 1, described notch 1 has the distortion of local by shell nosing treatment, therefore, design notch 1 not only can alleviate the weight of self-locking nut, and is convenient to ensure each mouth uniform force when closing up, and improves closing in quality; The outer wall of anti-slip section 8 arranges annular knurl tooth 3, avoids occurring skidding during assembling; The equipped hole 6 be communicated with tapped hole 2 is provided with in anti-slip section 8, in equipped hole 6, seal ring 4 is installed, and seal ring 4 outer end 0.5mm higher than nut body bottom surface 5, when assembling by nut body bottom surface 5 with seal ring 4 interference fit and crush seal circle 4, thus reach sealing effect, self-locking nut can be made so not only to have locking function, but also there is sealing, alleviate and the function of anti-slip.
