Abstract
The utility model discloses a kind of flanged surface self-locking nut, comprise hexagon nut body and flanged surface, described hexagon nut body is arranged at the upper end of flanged surface, hexagon nut body and flanged surface are integral type structure, described hexagon nut body offers tapped hole, described tapped hole runs through the flanged surface of lower end, the opening of tapped hole is provided with chamfering, the upper surface of described hexagon nut body is provided with compressing pressure point, pressure point is positioned at tapped hole circumferentially, and described pressure point destroys the partial thread formation of tapped hole opening.The utility model arranges compressing pressure point by punching equipment on the opposite side of hexagon nut body, thus increasing friction force prevents nut itself from getting loose, not reproducible use after nut screwing clamping, but has strong, locking, the safe and reliable feature of locking property.
Description
[technical field]
The utility model relates to the technical field of auto parts machinery, particularly a kind of technical field of nut.
[background technique]
Flanged locking nut is widely used in all important Yi Song positions such as large-scale, jubilee wagen, passenger vehicle, motorcycle, sedan car and engineering, mining machinery, light, hoisting machinery of bearing frequent vibration and impulsive load, ensures the normal operation of vehicle and machinery.Novel quick locknut provides two kinds of adjustment may.The first, by the accurate adjusting screw platform of handwheel.Secondly, user can also be separated mobile platform at an arbitrary position with leading screw, and with hand, it is shifted onto new position fast.Once it is locked to leading screw again, namely again carry out accurate adjustment by handwheel.The working principle of nut adopts the frictional force between nuts and bolt to carry out self-locking.But the reliability of this self-locking in dynamic load will reduce.In some important occasions, we will take some locking measures, ensure the reliability of nut check.Locking nut is exactly the locking measure of one wherein.The anti-loosing effect quality of locking nut depends primarily on the Interaction Force of nut and bolt thread engagement.The mode improving the Interaction Force of thread engagement has a variety of, and the worm structure improvement of such as nut, the nylon of nylon nut increases rough, the surface treatment etc. of screw thread.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of flanged surface self-locking nut, and structure is simple, has that locking property is strong, antivibration, locking, safe and reliable feature.
For achieving the above object, the utility model proposes a kind of flanged surface self-locking nut, comprise hexagon nut body and flanged surface, described hexagon nut body is arranged at the upper end of flanged surface, hexagon nut body and flanged surface are integral type structure, described hexagon nut body offers tapped hole, described tapped hole runs through the flanged surface of lower end, the opening of tapped hole is provided with chamfering, the upper surface of described hexagon nut body is provided with compressing pressure point, pressure point is positioned at tapped hole circumferentially, and described pressure point destroys the partial thread formation of tapped hole opening.
As preferably, the shape of described pressure point is triangle, and the quantity of pressure point is 2 ~ 4, and tapped hole place shaft axis is all equal with the perpendicular distance of each pressure point.
As preferably, the aperture at described pressure point inwall place is less than the aperture of tapped hole.
As preferably, the lower surface of described flanged surface is provided with anti-skidding groove, and the sectional shape of described anti-skidding groove is triangle.
As preferably, the outer rim of described flanged surface is provided with rounding.
The beneficial effects of the utility model: the utility model is by being set to integrated formed structure by hexagon nut body and flanged surface, eliminate when being subject to vibrating, situation about loosening easily is produced between pad and nut, increase the area of contact of nut and workpiece simultaneously, during assembling more firmly and pulling force larger, by punching equipment, compressing pressure point is set on the opposite side of hexagon nut body, thus increasing friction force prevents nut itself from getting loose, not reproducible use after nut screwing clamping, but there is strong, locking, the safe and reliable feature of locking property.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is the plan structure figure of a kind of flanged surface self-locking nut of the utility model;
Fig. 2 is the main TV structure figure of a kind of flanged surface of the utility model self-locking nut.
In figure: 1-hexagon nut body, 2-flanged surface, 3-pressure point, 4-tapped hole, 5-chamfering, the anti-skidding groove of 6-, 7-rounding.
[embodiment]
Consult Fig. 1, Fig. 2, a kind of flanged surface self-locking nut of the utility model, comprise hexagon nut body 1 and flanged surface 2, described hexagon nut body 1 is arranged at the upper end of flanged surface 2, hexagon nut body 1 and flanged surface 2 are integral type structure, described hexagon nut body 1 offers tapped hole 4, described tapped hole 4 runs through the flanged surface 2 of lower end, the opening of tapped hole 4 is provided with chamfering 5, the upper surface of described hexagon nut body 1 is provided with compressing pressure point 3, pressure point 3 is positioned at tapped hole 4 circumferentially, described pressure point 3 destroys the partial thread formation of tapped hole 4 opening, the shape of described pressure point 3 is triangle, the quantity of pressure point 3 is 2 ~ 4, tapped hole 4 place shaft axis is all equal with the perpendicular distance of each pressure point 3, the aperture at described pressure point 3 inwall place is less than the aperture of tapped hole 4, the lower surface of described flanged surface 2 is provided with anti-skidding groove 6, the sectional shape of described anti-skidding groove 6 is triangle, the outer rim of described flanged surface 2 is provided with rounding 7.
Utility model works process:
A kind of flanged surface self-locking nut of the utility model in the course of the work, distortion interference effect mainly through screw thread plays locking effect, wherein, hexagon nut body 1 and flanged surface 2 are integral type structure, the outer rim of flanged surface 2 is provided with rounding 7, the lower surface of flanged surface 2 is provided with anti-skidding groove 6, the sectional shape of described anti-skidding groove 6 is triangle, the setting of integral structure eliminates original pad, eliminate when being subject to vibrating, situation about loosening easily is produced between pad and nut, at the groove that the lower surface of flanged surface 2 has triangle anti-skidding, which increase the table area of contact of nut and workpiece, compare the combination that plain nut adds packing ring, more firmly and pulling force larger.Further, the upper surface of hexagon nut body 1 is provided with by punching equipment pressure point 3 compressing on the opposite side of hexagon nut body 1, the aperture at pressure point 3 inwall place is less than the aperture of tapped hole 4, pressure point 3 destroys the partial thread formation of tapped hole 4 opening, by the interference effect of pressure point 3 double thread, the effective torque part of its internal thread is suitably out of shape, thus increasing friction force prevents nut itself from getting loose, not reproducible use after nut screwing clamping, but there is strong, locking, the safe and reliable feature of locking property.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
