Abstract
The invention relates to a self-locking nut, which comprises a common nut, an embedding nylon body, an embedding groove and an embedding nylon ring, wherein the embedding nylon body is positioned at the tail of the common nut; the embedding groove is formed in the embedding nylon body; the embedding nylon ring is deformed and embedded in the embedding groove; and axial deformation pressure is applied to the tail of the common nut, the tail is subjected to axial micro deformation, and the embedding nylon ring is deformed to achieve the self-locking effect. After the self-locking nut with the structure is adopted, a bolt can be repeatedly used, the locking force is more reliable, and the equipment manufacturing cost and resources are greatly saved.
Description
Technical field
The present invention relates to a kind of nut, particularly a kind of inserted self-locking nut.
Background technique
Aboard; All adopted hexagonal self-locking nut and bolt that equipment is connected on the body in the past; In complex operating environment; The hexagonal self-locking nut still maybe be because the locking torque disappearance; Lose the locking effect; The equipment of connection is come off from body, thereby cause the afunction of equipment, produce security incident.Therefore the coupling mechanism force and the reliability that improve self-locking nut become urgent problem.
Summary of the invention
Technical problem to be solved by this invention provides a kind of self-locking nut that improves the mechanized equipment connection reliability.
A kind of self-locking nut, this self-locking nut comprise plain nut, inlay nylon body, mosaic groove, inlay nylon ring; Inlay the afterbody that nylon body is positioned at plain nut, dug mosaic groove, inlay nylon ring and embed in the mosaic groove through the distortion back in the inside of inlaying nylon body; Afterbody at plain nut applies axial deformation pressure then, allows it produce axial micro-deformation, makes to inlay nylon ring generation deformation and reach oneself's locking.
Self-locking nut of the present invention is assemblied in the self-lock force that back distortion nylon ring produces on the bolt can be firmly locked on bolt with nut; Common loosening phenomenon when having avoided regular screw threads to connect; And, can also avoid other normal locking phenomenon that occurs in self-locking nut assembling back through the locking of distortion nylon ring.Bolt can be repeatedly used after the structure of employing self-locking nut of the present invention, has saved equipment manufacture cost and resource greatly.
Description of drawings
Fig. 1 is the structural representation of self-locking nut of the present invention;
Embodiment
Can find out that from Fig. 1 inserted self-locking nut involved in the present invention comprises: plain nut 1, inlay nylon body 2, mosaic groove 3, inlay nylon ring 4.
The present invention inlays nylon body 2 in plain nut 1 afterbody increase; Inlay nylon body 2 inner excavation mosaic grooves 3; Plain nut 1 shapes the back and is embedded in nylon ring 4 at mosaic groove 3; Inlaying nylon ring 4 could embed after being out of shape; After the embedding again the afterbody at plain nut 1 apply axial deformation pressure; Allow it produce axial micro-deformation, reach oneself's locking thereby allow it produce deformation like this.The width of mosaic groove 3 and the degree of depth are confirmed according to the size of inlaying nylon ring 4, inlay the size of nylon ring 4 and are then confirmed by the coupling mechanism force size of nut as required.
The present invention takes cheaply, and machining process carries out overall structure processing; Cut out the groove of inlaying nylon ring at inlaid body part endoporus place then; Groove dimensions is confirmed according to the coupling mechanism force size that test draws; When to be assembled nylon ring is inlaid into body, then inlaid body structure division afterbody is exerted pressure.After the assembling of the self-locking nut of other structure, tend to cause bolt not reuse, and the bolt among the present invention is repeatedly reusable because of after the self-locking distortion bolt being destroyed.The present invention is simple in structure, and processability is good, and product is safe and reliable, can be popularized and applied to various mechanical industries.
Claims (1)
1. a self-locking nut comprises plain nut (1), it is characterized in that: this self-locking nut also comprises to be inlayed nylon body (2), mosaic groove (3), inlays nylon ring (4); Saidly inlay the afterbody that nylon body (2) is positioned at plain nut (1), dug mosaic groove (3), inlay nylon ring (4) and embed in the mosaic groove (3) through the distortion back in the inside of inlaying nylon body (2); Afterbody at said plain nut (1) applies axial deformation pressure, allows it produce axial micro-deformation, makes to inlay nylon ring (4) generation deformation and reach oneself's locking.
