Abstract
The invention relates to an anti-loosening method for the connection of a hexagon nut and a bolt, which relates to a fastener. The anti-loosening method comprises the following steps: firstly, evenlyforming a transverse slot on the nut in the height direction and the position which is far away from the end surface by 2-3 thread pitches along an angle of the nut at an interval, leading the depth of the slot to achieve the root part of a thread, then matching the nut with the bolt and screwing, using an iron wedge for cutting in from the transverse slot, and leading the part above the slot to cock upwards. The anti-loosening method can not only solve the problem that the connection of the nut and the bolt is loosed, but also improve the connection strength of the fastener. The anti-loosening method has the advantages of balanced loading of the nut, convenient installation and disassembly, simple and easy operation, good practicality and the like.
Description
Technical field
The present invention relates to fastening piece, the connecting means of particularly a kind of hexagon nut and bolt.
Background technique
Hexagon nut is common fastening piece, all is widely used in fields such as aviation, metallurgy, transportation, mines.Because nut is when being connected with bolt, screw pair leaves the gap, therefore, when its under heavily loaded, large impact operating mode, when particularly bearing oscillation exchange load, the fastening effect of plain nut tends to weaken, inefficacy finally causes being threaded.Nut and bolted anti-loose method adopt modes such as improving pretightening force, destruction screw pair usually.Wherein, improve the method for pretightening force (as adding elastic washer), because the influences such as load, vibration, temperature variation that are hit, pretightening force is difficult to stablize, and makes bolt and nut produce relative movement, thereby can cause thread failure; And come locking method by the permanent destruction screw pair, shortcoming such as have then that reusability is poor, installing/dismounting inconvenience, stand under load are inhomogeneous.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, a kind of hexagon nut and bolted anti-loose method are provided, not only solve nut and bolted loosening problem, and improved the join strength of bolt and nut.
Technical solution of the present invention is:
A kind of hexagon nut and bolted anti-loose method, it is characterized in that: at first with nut its short transverse, apart from 2～3 pitch positions of end face, along the nut angle every a uniform transverse groove crack of offering, the groove crack degree of depth is to thread root, then described nut is cooperated with bolt tighten after, cut from the transverse groove crack with the iron wedge, make the groove crack be upturned with top.
The present invention compared with prior art has following advantage and beneficial effect:
Anti-loose method of the present invention is taked to destroy screw pair and is realized, the equilibrium of nut stand under load the unbalance loading situation can not occur; Since not permanent damage, therefore, installation, convenient disassembly, and simple to operate, easy row, practicability is good.
Description of drawings
Fig. 1 is a kind of structural representation (plan view) of lock nut;
Fig. 2 is the plan view of Fig. 1;
Fig. 3 is the schematic representation of a kind of hexagon nut and bolted anti-loose method.
Embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, 2, 3, a kind of hexagon nut and bolted anti-loose method, at first with hexagon nut 1 its short transverse, apart from 2～3 pitch positions of end face, along nut exterior angle 1-1 every uniform three a roads transverse groove crack 1-2 that offers, the groove crack degree of depth is to thread root, then described nut 1 is cooperated with bolt 2 tighten after, cut from the 1-2 of transverse groove crack with iron wedge 3, make the groove crack be upturned with top 1-3.Because local pitch changes, the gap of having eliminated screw pair 4, therefore, nut and bolt can be regarded an integral body as, have not only solved nut and bolted locking problem, and have improved the rigidity of fastening piece.
During dismounting, nut top 1-3 is smash flat downwards, make it recover thread pitch, promptly detachable.
Claims (1)
1, a kind of hexagon nut and bolted anti-loose method, it is characterized in that: at first with nut (1) its short transverse, apart from 2～3 pitch positions of end face, along nut exterior angle (1-1) every a uniform transverse groove crack (1-2) of offering, the groove crack degree of depth is to thread root, then described nut (1) is cooperated with bolt (2) tighten after, cut from transverse groove crack (1-2) with iron wedge (3), make the groove crack be upturned with top (1-3).
