Abstract
The utility model discloses a ratchet wedge face lock nut, including first nut, second nut and screw rod, its characterized in that: first nut, the equal threaded connection of second nut in screw rod, first nut bottom is equipped with align to grid's first connection tooth, second nut top align to grid has the second connection tooth with first connection tooth matched with. This practicality has following advantage: 1. the cold stamping batch processing is carried out by adopting the stamping die, so that the manufacturing cost is low; 2. the locking modes of a spring washer, a locking pad, a locking pin, a stop pad and the like of a conventional bolt are eliminated, and the operation is simple; 3. the ratchet wedge surface locking nut can realize permanent locking of the connecting piece, never becomes loose and ensures reliable connection.
Description
Technical Field
The utility model relates to a mechanical design and manufacturing technical field specifically indicate a ratchet wedge face lock nut.
Background
The locking mode of the nut is various, and especially in the working condition occasion involving vibration, the locking mode is very important for fastening the bolt on the machine member. Due to vibration, the nut can slowly rotate, so that the screw becomes loose, or the nut becomes loose due to the fact that the screw deforms due to frequent vibration. The prior spring washer is easy to fatigue failure, and is difficult to ensure the loosening and falling of the nut, namely the bolt fastener is loosened in the occasion of long-term rest or vibration. Brings serious hidden troubles to equipment and components thereof, especially in the fields of rail transit, engineering machinery, automobile engineering and the like.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome above technical problem, provide a ratchet wedge face lock nut.
In order to solve the technical problem, the utility model provides a technical scheme is a ratchet wedge face lock nut, including first nut, second nut and screw rod, its characterized in that: first nut, the equal threaded connection of second nut in screw rod, first nut bottom is equipped with align to grid's first connection tooth, second nut top align to grid has the second connection tooth with first connection tooth matched with.
Preferably, the first nut is meshed with the second connecting teeth on the second nut through the first connecting teeth.
Preferably, the first connecting teeth and the second connecting teeth are both ratchet teeth with wedge-shaped surfaces.
Preferably, the first nut, the second nut and the screw are all made by a stamping die through cold stamping.
Compared with the prior art, the utility model have following advantage: 1. the cold stamping batch processing is carried out by adopting the stamping die, so that the manufacturing cost is low; 2. the locking modes of a spring washer, a locking pad, a locking pin, a stop pad and the like of a conventional bolt are eliminated, and the operation is simple; 3. the ratchet wedge surface locking nut can realize permanent locking of the connecting piece, never becomes loose and ensures reliable connection.

As shown in the figure: 1. the first nut, 2, the second nut, 3, the first connecting workpiece, 4, the second connecting workpiece, 5, the screw rod, 6, the first connecting tooth, 7 and the second connecting tooth.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
With the attached drawings, the ratchet wedge surface locking nut comprises a first nut 1, a second nut 2 and a screw rod 5, and is characterized in that: first nut 1, the equal threaded connection of second nut 2 are in screw rod 5, 1 bottom of first nut is equipped with align to grid's first connection tooth 6, 2 top align to grid of second nut has the second connection tooth 7 with first connection tooth 6 matched with.
The first nut 1 is meshed with the second connecting teeth 7 on the second nut 2 through the first connecting teeth 6.
The first connecting teeth 6 and the second connecting teeth 7 are both ratchet teeth with wedge-shaped surfaces.
The first nut 1, the second nut 2 and the screw 5 are all manufactured by a stamping die through cold stamping processing.
The utility model is usually used for loosening the connecting pieces in practical use, as shown in fig. 1, in order to fix the first connecting piece and the second connecting piece together and ensure that the first connecting piece and the second connecting piece are not loosened, the screw rod is sequentially penetrated through the first connecting piece and the second connecting piece, and then the second nut is screwed on the screw rod, because the tooth point of the second connecting tooth on the second nut is upward, the non-ratchet tooth surface of the second connecting tooth is contacted with the first connecting piece, tightening the second nut to 90% of the pre-tightening force, tightening the first nut to the screw rod again, because the tooth tip of the first connecting tooth on the first nut faces downwards, the first nut is screwed to 100 percent of the pretightening force, engaging with the second coupling teeth of the second nut, pressing the second nut by tightening the first nut, the tooth shapes of the second nut and the first nut can be locked with each other, so that the nut can be prevented from loosening. Because the wedge-shaped tooth form angle meets the interlocking requirement, under the working condition, even if the vibration is intensified, when the screw rod is extended and deformed, the two nuts generate dislocation due to deformation clearance teeth, the compensation is carried out, and the locking is continued; the interlocking can be perfectly realized without vibration static working conditions, and the locking is never loosened; the friction between the nuts will always be present.
The present invention and the embodiments thereof have been described above, but the description is not limited thereto, and the embodiment shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should understand that they should not be limited to the embodiments described above, and that they can design the similar structure and embodiments without departing from the spirit of the invention.
