Description
Technical field
The present invention relates to stop nut technical fields, in particular to a kind of stop nut and its manufacturing method.
Background technology
Nut is widely used in the ground such as various mechanical equipments, life furniture, electric appliance as a kind of common component of machine
Side.Nut is usually used in combination with screw, bolt or screw rod and fixes various parts.It takes regular exercise or shakes for some
Mechanical equipment, such as railway, usage time grow, and common nut is susceptible to loosening or even falls off, so as to cause machine
Failure or damage even cause great safety accident.
In order to avoid the above situation occurs, stop nut comes into being.It is existing loosen nut have it is following several：(1) most
It is simply superimposed using two nuts, plays anti-loosing effect；(2) nut and lock washer are applied in combination, such spiral shell
Around female jagged, these notches are both that the impetus of tightening tool and lock washer bayonet are caught in place；(3) it slots
Nut does not do other processing after fluting, and principle, which is it, can be converted to frictional force expansive force between bolt and slot nut
To reach self-locking effect.
There is following disadvantages for existing stop nut：(1) self-lock force is small, big for vibration amplitude, the operating mode of time length
When, there is failure may；(2) reusing anti-loosing effect reduces obviously；(3) existing slotted stop nut groove width is in 1-3
Times screw pitch, nut body once collide with it is also possible to random tooth occurs and can not tighten.
Invention content
For the above-mentioned prior art the problem of, a kind of stop nut of present invention offer and its manufacturing method, wait for spiral shell
After bolt is tightened, occur plastic deformation nut cut bolt thread can be answered at slot elastic deformation generate pressing force, to reach
To nut loosening is prevented, achieve the effect that self-locking.
To achieve the above object, the present invention provides the following technical solutions：
A kind of stop nut, including nut body and the threaded hole set on nut body center, described nut body one end
Equipped with a cylinder, the threaded hole runs through nut body and cylinder, and the cylinder is along the circumferential direction equipped with and cuts slot, described
It cuts slot and plastic deformation has occurred to nut body direction along cylinder axis.
Further, the well width that cuts is 0.5-1 screw pitch.
Further, the slot length that cuts is more than half of circumference.
Further, the slot that cuts is 2, and the opening direction that slot is cut described in 2 is opposite.
Further, the plastic deformation for cutting slot generation is to cut slot to be pressed.
In addition, the present invention also provides a kind of manufacturing methods such as above-mentioned stop nut, including：
Nut body shape is processed, and nut body one end is equipped with a cylinder；
Threaded hole is processed in nut body and center；
At least one is processed on the cylinder cuts slot；
To cutting slot pier pressure, make to cut slot in an axial direction to the generation plastic deformation of nut body direction.
Beneficial effects of the present invention are as follows：
1, due to having carried out pier pressure to cutting slot, make to cut slot and produce plastic deformation, therefore, antidetonation strong to the pressing force of spiral
It has excellent performance, is particularly suitable for railway, automobile and other industries；
2, it is no more than a screw pitch since it cuts well width, therefore which obviate random dental phenomenons.And it is repeatable to utilize 5-6
It is secondary.
Description of the drawings
Fig. 1 be the present invention do not press before stop nut structural schematic diagram；
Fig. 2 is the stop nut structural schematic diagram after the pressing of the present invention.
In figure：1-nut body, 2-cylinders, 21-cut slot, 22-pressing seams.
Specific implementation mode
It is right with reference to the attached drawing of the present invention in order to make those skilled in the art more fully understand technical scheme of the present invention
Technical scheme of the present invention carries out clear, complete description, and based on the embodiment in the application, those of ordinary skill in the art exist
The other similar embodiments obtained under the premise of not making creative work, shall fall within the protection scope of the present application.
Embodiment one：
As depicted in figs. 1 and 2, a kind of stop nut, including nut body 1 and the threaded hole set on nut body center,
1 one end of the nut body is equipped with a cylinder 2, and the threaded hole runs through nut body 1 and cylinder 2,2 edge of the cylinder
Circumferencial direction cuts slot 21 equipped with 2, and 21 width of slot that cuts is 0.5-1 screw pitch, and the present embodiment is preferably 0.5 screw pitch, is cut
21 length of slot is more than half of circumference, and the opening direction that slot 21 is cut described in 2 is opposite.It is described to cut slot 21 along cylinder 2 axially to spiral shell
Pier pressure is passed through in 1 direction of maternal body, and plastic deformation has occurred, and the plastic deformation for cutting the generation of slot 21 is to cut slot 21 to be pressed,
2 surface of cylinder forms two pressing seams 22.
In addition, the present invention also provides a kind of manufacturing methods such as above-mentioned stop nut, including：
1 shape of nut body is processed, and 1 one end of nut body is equipped with a cylinder 2；
Threaded hole is processed in nut body 1 and 2 center of cylinder；
2 are processed on cylinder 2 cuts slot 21；
To cutting 21 pier pressure of slot, make to cut slot 21 in an axial direction to the generation plastic deformation of 1 direction of nut body.
In use, when bolt is up rotated arrival pressing seam 22 by bottom along nut body 1, since screw pitch reduces,
It needs bolt could to be rotated by pressing at seam 22 with strong external force, under the action of strong external force, the circle that is connected with nut body 1
Cylinder 2 will generate bolt the reaction force of one same intensity, be compressed to bolt.After bolt is tightened, nut
Two cut bolt thread can all be answered at slot 21 elastic deformation generate pressing force achieve the effect that self-locking to prevent nut loosening.
It is no more than a screw pitch since it cuts well width, therefore which obviate random dental phenomenons.
Contrast test：
Be provided only with 2 and cut slot, not to cut slot carry out pier pressure stop nut as a control group, the embodiment of the present invention one
