Abstract
The invention discloses a method for preventing a lock bolt from loosening and a lock bolt assembly. According to the invention, at least one key slot is made on the thread section of a bolt, and a key block is inserted into the key slot, then the bolt is screwed into a nut, thread teeth on the nut are used for extruding the key block to be deformed, a thread in closely matched with the nut is extruded on the key block, and then the thread of the nut can be tightly matched with the thread extruded on the key block to generate a locking force, so as to achieve the aim of preventing the lock bolt from loosening. The method for preventing the lock bolt from loosening and the lock bolt assembly not only have the advantages of being reliable in self-locking, good in strength and light in weight, but also has the advantages of being low in requirements on heat treatment, easy to product, low in production cost, convenient to use and the like.
Description
Technical field
the present invention relates to a kind of method and lock bolt assembly parts that prevents that lock bolt is loosening, belong to the self-locking screw technical field.
Background technique
common bolt does not generally all have auto-lock function, is used in general occasion and can satisfies usage requirement basically.But be used in the bigger occasion of some vibrations, because vibration can cause bolt looseness.So, must use a kind of shockproof lock bolt in some special occasions.Lock bolt in the market is a lot, and structure also has nothing in common with each other.But these lock bolt ubiquities and are made trouble, cost of production problem of higher, but also some exists the not so good problem of intensity, so its using effect is very not desirable.
Summary of the invention
the objective of the invention is to; Provide a kind of reliable lock, intensity good, in light weight, to heat treated less demanding and make easily, cost of production is low prevents method and the lock bolt assembly parts that lock bolt is loosening, to overcome the deficiency of existing technology.
technological scheme of the present invention is achieved in that a kind of loosening method of lock bolt that prevents of the present invention is; On the thread section of bolt, produce earlier at least one keyway; And in keyway, insert the key piece; Then bolt is screwed in nut, the key piece is carried out extrusion-deformation, on the key piece, squeeze out and the friction tight screw thread of nut through the thread on the nut; The screw thread that is squeezed out on screw thread and the key piece of nut closely is combined together and produces coupling mechanism force, thereby reach the purpose that prevents that lock bolt is loosening.
above-mentioned key piece is for adopting nylon material or adopting hardness to be made less than the metallic material of nut material hardness.
according to of the present invention a kind of lock bolt assembly parts that said method makes up are: this lock bolt assembly parts comprises bolt, on the thread section of bolt, is provided with at least one keyway, is provided with the key piece in the keyway.
In
aforesaid lock bolt assembly parts, the length direction direct-axis of said keyway is provided with.
In
aforesaid lock bolt assembly parts, the bottom shape of said keyway is arc, trapezoidal or stepped shape.
In
aforesaid lock bolt assembly parts, the bottom shape of said key piece is corresponding with the bottom shape of keyway.
In
aforesaid lock bolt assembly parts, said key piece is nylon or the hardness Steel Work less than bolt.
are owing to adopted technique scheme; The present invention only need mill out at least one keyway at the thread section of bolt; And in keyway, insert the key piece, when bolt is screwed in nut, utilize the thread on the nut that the key piece is carried out extrusion-deformation; On the key piece, squeeze out and the friction tight screw thread of nut, make the screw thread of nut cooperate the generation coupling mechanism force with the thread biting locking of key piece; Reach the function of self-locking, thereby can prevent to produce between lock bolt and the nut in use loosening reliably, effectively.So the present invention compared with prior art, the present invention has not only that self-locking is reliable, intensity good, lightweight advantage, but also has advantage such as heat treated less demanding, easy making, cost of production be low, easy to use.
Description of drawings
Fig. 1 is a lock bolt assembling unit structure schematic representation of the present invention;
Fig. 2 is the structural representation of lock bolt assembly parts of the present invention when being connected with nut.
Be labeled as among
figure: 1-bolt, 2-thread section, 3-keyway, 4-key piece, 5-nut.
Embodiment
are further described the present invention below in conjunction with accompanying drawing and embodiment, but not as the foundation to the present invention's restriction.
embodiment: a kind of method that prevents that lock bolt from becoming flexible of the present invention is improved on existing screw bolt and nut connection basis and is formed; This method is on the thread section of existing bolt, to produce earlier 1～4 keyway; And in each keyway, all inserting a key piece, the key piece can adopt nylon material or adopt hardness to be made less than the metallic material of nut material hardness; Then bolt is screwed in the nut that matches with it and use; Through the thread on the nut key piece is carried out extrusion-deformation; On the key piece, squeeze out and the friction tight screw thread of nut; The screw thread that is squeezed out on screw thread and the key piece of nut closely is combined together and produces coupling mechanism force, thereby reach the purpose that prevents that lock bolt is loosening.
according to of the present invention a kind of lock bolt assembly parts that said method makes up are: the structural representation of this lock bolt assembly parts is as shown in Figure 1; Comprise existing bolt 1; On the thread section 2 of bolt 1, be provided with at least one keyway 3, be provided with key piece 4 in the keyway 3; The length direction direct-axis of its keyway 3 is provided with; Can the bottom shape of keyway 3 be made as the shape of arc, trapezoidal or stepped shape, the bottom shape with key piece 4 is made into corresponding with the bottom shape of keyway 3 simultaneously; Key piece 4 can adopt nylon material or hardness to make less than the steel of bolt 1 hardness.
are faced locking principle of the present invention and method for using down and are further described.
are as shown in Figure 2, add man-hour carrying out bolt, only need mill out at least one keyway 3 at the thread section 2 of bolt 1, and keyway 3 in insertion key piece 4.When bolt 1 is screwed in nut 5, utilize the thread on the nut 5 that key piece 4 is carried out extrusion-deformation, on key piece 4, squeeze out and nut 5 friction tight screw threads, make the screw thread of nut 5 cooperate the generation coupling mechanism force with the thread biting locking of key piece 4; Reach the function of self-locking, it is reliable that the present invention has self-locking, and intensity is good, and is in light weight, to heat treated less demanding, makes the characteristics that cost of production is low easily.
