Abstract

The utility model discloses a spherical high-locking nut, comprising a high-locking nut with internal thread, wherein a convex spherical surface is arranged on one end of the high-locking nut, a spherical washer is arranged on the convex spherical surface of the high-locking nut, a concave spherical surface is arranged on the spherical washer in fit with the convex spherical surface of the high-locking nut; neck breaking groove on the outside surface of the high-locking nut. A slotting and locking structure on the high-locking nut and the spherical washer are used and a certain twisting momentis applied on the twisting area of the high-locking nut to twist off the neck breaking groove of the nut, thus pre-tightening force is generated and the nut is connected with a sandwich plate by spherical washer adjustment. The spherical high-locking nut is quickly assembled and the reliability of the assembled nut is good and the loosening prevention function is very good. The spherical high-locking nut has advantages of simple structure, easy production and good use effect.

Description

A kind of sphere Closely locking nut
Technical field
The utility model relates to a kind of sphere Closely locking nut, belongs to nut technical field in the fastening piece.
Background technique
At present, some of aircraft interlayer are local because interlayer itself has gradient, adjust angle when needing assembling, avoid that bolts and nuts can not vertically connect on the inclined-plane.Can not satisfy the requirement of this assembly structure with the Closely locking nut of conventional structure, though and traveling self-locking nut can be adjusted angle, assembling speed is slow, assembly precision requires high, and maintenance is inconvenient, and anti-loosening property and load performance are good inadequately, volume is bigger, and has increased the weight of aircraft assembling.Therefore, nut of the prior art still can not satisfy the needs of use
The model utility content
The purpose of this utility model is: providing a kind of can carry out the rapid adjustment assembling on less than 7 ° inclined-plane and have reliable and stable tightness and good fatigue resistance and the sphere Closely locking nut that volume is little, weight is lighter at aircraft interlayer gradient α, to overcome the deficiencies in the prior art.
The utility model is achieved in that the utility model is to improve to form on the existing Closely locking nut basis that is provided with internal thread, promptly the end at Closely locking nut is provided with protruding sphere, and on the position of the protruding sphere of Closely locking nut, be provided with a spherical washer, on spherical washer, be provided with the concave spherical surface that matches with the protruding sphere of Closely locking nut.
On the outer side surface of above-mentioned Closely locking nut, be provided with cut-off neck slot.
The both sides of cut-off neck slot also are respectively equipped with locking mechanism and twist into two parts structure on the outer side surface of above-mentioned Closely locking nut.
The internal thread of above-mentioned Closely locking nut is the self-locking type fine thread of bottom made in U.S.A band circular arc.
Above-mentioned Closely locking nut and spherical washer are the stainless steel material structure.
Owing to adopted technique scheme, the utility model can be installed on interlayer inclination α is less than or equal to 7 ° inclined-plane, when high locked bolts being passed spherical washer and enters the threaded portion of Closely locking nut, apply rational twisting moment (this moment, twisting moment was determined by the cut-off neck slot size) by the twisting structure of twisting into two parts partly to Closely locking nut cut-off neck slot one end, cut-off neck slot is twisted into two parts, be that Closely locking nut just obtains corresponding pretightening force when cut-off neck slot is twisted into two parts, Closely locking nut is in this rotary course, its protruding land portions is partly passed through being connected of high locked bolts with the concave spherical surface of spherical washer, spherical washer is just adjusted to Closely locking nut and high locked bolts on the direction connected vertically this moment, because the locking mechanism that the screw thread of Closely locking nut has has stoped the mutual rotation of bolts and nuts.Therefore the utility model compared with prior art, the utility model not only has can realize the fast advantage of assembling, but also have simple in structure, easy production, easy for installation, volume is little, reliability in light weight, after installing is high and have advantages such as good fatigue resistance and locking effect.Simultaneously, the utility model has solved the aircraft interlayer and has had the problem that gradient is difficult to install.

Accompanying drawing 3 is a spherical washer structural representation of the present utility model;
Structural representation when accompanying drawing 4 is installed and used for the utility model.
Embodiment
Embodiment of the present utility model: as Fig. 1, Fig. 2, shown in Figure 3, the utility model is made up of Closely locking nut 1 that is provided with internal thread 5 and spherical washer 2, during making, produce protruding sphere 4 simultaneously at an end of Closely locking nut 1, and on the position of the protruding sphere 4 of Closely locking nut 1, be provided with a spherical washer 2, the one side of spherical washer 2 is made into the plane, on the another side of spherical washer 2, produce the concave spherical surface 8 that matches with the protruding sphere 4 of Closely locking nut 1, Closely locking nut 1 and spherical washer 2 can adopt conventional metallic material to make, but when using on the aircraft, preferably adopt stainless steel material to make; On the outer side surface of Closely locking nut 1, make a circle cut-off neck slot 3 then, and the both sides of cut-off neck slot 3 are produced locking mechanism 6 respectively and are twisted into two parts structure 7 on the outer side surface of Closely locking nut 1; The internal thread 5 of Closely locking nut 1 is made into the self-locking type fine thread of bottom made in U.S.A band circular arc.
When using the utility model, in assembling, to pack in the sandwich plate 10 with the high locked bolts 9 that Closely locking nut 1 of the present utility model is used, spherical washer 2 is penetrated high locked bolts 9 to be contacted with sandwich plate 10, Closely locking nut 1 is screwed on the high locked bolts 9, apply certain twisting moment by special tool and twisting into two parts on the structure 7, thereby cut-off neck slot 3 is twisted into two parts, this moment, protruding sphere 4 parts of Closely locking nut 1 were connected with spherical washer 2 adjustment.
The environment that Closely locking nut 1 uses has determined Closely locking nut 1 that pretightening force and coupling mechanism force preferably will be arranged, and pretightening force is to be determined by the moment of twisting into two parts of twisting into two parts groove 3, if Closely locking nut 1 twist into two parts groove 3 to twist into two parts moment too small, the pretightening force that produces just can not make Closely locking nut 1 and spherical washer 2 or sandwich plate 10 be connected firmly, if Closely locking nut 1 twist into two parts groove 3 to twist into two parts moment excessive, during the pretightening force that produces can make Closely locking nut 1 and spherical washer 2 is connected sandwich plate 10 is applied excessive pressure, make sandwich plate 10 be in stress for a long time and be out of shape.The locking torque of Closely locking nut 1 produces by internal thread 5 region deformations, the size of locking torque has determined the locking property and the vibration resistance of nut, and excessive locking torque also can cause damage to the screw thread of high locked bolts 9, have only distortion could guarantee the mechanical property requirement, and then satisfy the clamping needs by effective control internal thread 5 zones.
