Abstract
The invention relates to the technical field of nuts, in particular to a locknut. The locknut comprises a nut body, and the nut body has the standard size; a certain pressure is exerted to the interior of the nut body within one small range or multiple spaced small ranges of one end of the nut body to form a central protrusion of a thread towards the nut body within the corresponding small range; and a production method of the locknut comprises the process steps of firstly, material section, secondly, cold heading or hot forging, thirdly, turning, fourthly tapping, fifthly, extrusion or stamping, sixthly, heat treatment, and seventhly surface treatment. According to the locknut, through deformation within the small range of one end of the nut, tight fit of the nut and a bolt is achieved, conditions of falling and loosening are not prone to happening, and the use performance of the nut is improved.
Description
Technical field
The present invention relates to nut technical field, especially a kind of stop nut and production method thereof.
Background technology
The most general nut is all standard component, its with bolt engagement process in need to utilize elastomeric element increase both it
Between pressure, and then promote the extruding force between screw thread and screw thread and realize fastening between the two, situation about not loosening.
Summary of the invention
The invention aims to solve the deficiency of above-mentioned technology and a kind of stop nut and production method thereof are provided, its
Can effectively realize the steady pressure produced when nut self coordinates with bolt so that nut can be firmly fixed on bolt,
It is not susceptible to loosen.
In order to achieve the above object, the stop nut designed by the present invention, it includes nut body, described nut body
For standard size；The multiple little scope at some or the interval of wherein one end of nut body is executed inside nut body
The screw thread adding certain pressure and formed in this little scope protrudes to the center of nut body.
Technique scheme, applies certain pressure, in the range of causing this in the little scope of one end of threaded body
Screw thread inside threaded body is inwardly projecting, and causes and be smaller than remaining between the screw thread in the diametric(al) in this region
The spacing between screw thread in region.And in use, when nut body coordinates with screw rod, when the little scope of this after pressurized
Interior screw thread and the threaded engagement on screw rod, owing to there is deformation in this little scope, then can make between the screw thread in this region
Cooperation time the stable extruding force that produces so that coordinate firmly between the two, closely, be not susceptible to situation about loosening.
The deflection of the screw thread in above-mentioned little scope is less than or equal to the 20% of thread height.As preferably, its deflection is
The 5-15% of thread height.
The nut body outer surface applying pressure one end is provided with an arc groove or is arranged at intervals with ringwise
Multiple arc grooves, the thickness of the region inner nut body of described arc groove is less than the thickness of the nut body in remaining region
Degree；Execute stressed little range areas to be then positioned at inside corresponding arc groove.The design of this structure can effectively make to apply
The sidewall of the nut body in the little scope of pressure is relatively thin, thus only occurs in this little scope in applying press process
Deformation, does not results in whole nut body and changes in circularity, and then can ensure the normal usage energy of nut body.
It is provided with in the conical surface, and the region at conical surface place at the nut body outer surface being provided with arc groove one end, spiral shell
The thickness of female body end is minimum；Described arc groove is partially or fully positioned at the regional extent at conical surface place.This conical surface
The design of structure, can preferably realize offering arc groove in the appearance of nut body, conveniently be processed it, it is possible to decrease add
Work cost, and do not affect serviceability.
The quantity of described arc groove is six, and each arc groove is arranged at six of nut body outer surface
End corresponding to plane.
Little scope in wherein one or two or three arc grooves of six arc grooves applies pressure and causes
Deformation.
The production method of a kind of stop nut, processing step is: 1. selection；2. cold-heading or forge hot；3. turning；4. tapping；
5. extruding or punching press；6. heat treatment；7. surface processes.
Stop nut obtained by the present invention and production method thereof, it is reality by the deformation in the little scope of nut one end
Existing closely cooperating between nut and bolt, is not susceptible to the situation coming off, loosening, improves the serviceability of nut.
