In view of the above-mentioned defect of prior art, the locking assembled nut of controllable pressure type that the utility model provides a kind of tapered cup nut to open groove, greatly to improve the anticreep performance of nut and to reduce the fatigue strength of bolt.
The locking assembled nut of controllable pressure type that the utility model provides, comprise mother nut and attaching nut, the mother nut structure that is formed in one, comprise hexagon nut and tapered cup nut, wherein tapered cup nut has first end and the second less end of diameter that diameter is larger, first end and hexagon nut are integrated to link together, and the internal thread of attaching nut and the outside thread of tapered cup nut match, and make attaching nut be screwed into tapered cup nut.The main shaft of hexagon nut and tapered cup nut is identical, eliminates the eccentricity issues of tapered cup nut, can simplify actual processing technology.In order to improve anti-loosening property, open uniformly multiple grooves at tapered cup nut along the direction of self length, in the time that attaching nut is screwed into tapered cup nut, can make the tapered wall of tapered cup nut be extruded inward like this, screw thread stress distribution is even, and bolt is formed to a kind of radial pressure uniformly.
Preferably, tapered cup nut outside thread be standard thread.
Preferably, tapered cup nut outside thread must firm screw thread for executing.
Preferably, tapered cup nut is opened 4 grooves uniformly along major axes orientation, and 4 grooves are about main shaft symmetry.
Preferably, the width of groove is 0-3mm.
Preferably, the width of groove is 0.5-1.5mm.
In preferred embodiment of the present utility model, adopt mother nut, attaching nut, bolt and pad etc. to form a fastener, mother nut comprises hexagon nut and tapered cup nut, to be that first end is one-body molded with the larger end of diameter of tapered cup nut be connected hexagon nut, the main shaft of hexagon nut and tapered cup nut coincides, tapered cup nut is opened 4 grooves uniformly along major axes orientation, and 4 grooves are about main shaft symmetry.Pad is inserted in bolt from the screw rod of bolt, is then inserted in mother nut with the bolt of pad from hexagon nut one side of mother nut, and last attaching nut is screwed into the tapered cup nut of mother nut, and whole element is fastened.
The locking assembled nut of controllable pressure type that the utility model provides, eliminate the eccentricity issues of hexagon nut and tapered cup nut, make its axis overlapping, and tapered cup nut is at the multiple grooves of opening along self length direction symmetry, simplified processing process so greatly, and in improving anti-loosening property, screw thread stress distribution is even, can not affect the fatigue strength of bolt.
Below with reference to accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is described further, to understand fully the purpose of this utility model, feature and effect.

Embodiment
The locking assembled nut of controllable pressure type of preferred embodiment of the present utility model is made up of mother nut and attaching nut.
As shown in Figure 1, be the mother nut 100 of the locking assembled nut of controllable pressure type of this preferred embodiment.The structure that is formed in one, comprises hexagon nut 110 and tapered cup nut 120.Tapered cup nut 120 comprises first end 121 and the second end 122, and the inner diameter of first end 121 is greater than the inner diameter of the second end 122.Wherein first end 121 is connected with hexagon nut 110, and its inner diameter is greater than the inner diameter of hexagon nut 110.And hexagon nut 110 overlaps with the longitudinal axis of tapered cup nut 120, be that main shaft is consistent, there is not eccentricity issues, simplified processing process greatly, in order to improve the anti-loosening property of nut, open uniformly multiple grooves at tapered cup nut 120 along major axes orientation, the number of groove is decided by concrete nut, can be 2,3 or multiple.The width of groove is also to arrange according to the size of concrete nut, and the width of general groove can be 0-3mm, is more preferably 0.5-1.5mm.In the time of nut lockk bolt, the stress distribution of double thread is even like this, can not affect the fatigue strength of bolt.In the present embodiment, as shown in Figure 1, tapered cup nut 120 is opened 4 grooves 123 along major axes orientation, and the width of each groove 123 is 1mm.Tapered cup nut 120 is provided with internal thread and outside thread, and internal thread and bolt match, and outside thread and attaching nut match.In the present embodiment, the outside thread of tapered cup nut 120 adopts that execute must firm screw thread, to improve the anti-loosening property of nut combinations.In practical operation, the outside thread of tapered cup nut 120 also can adopt any thread pattern that can improve nut combinations anti-loosening property.
Fig. 2 is attaching nut 200, its inner diameter is less than the first end 121 of tapered cup nut 120 in Fig. 1, be greater than the second end 122 of tapered cup nut 120, in the time that attaching nut 200 is screwed into tapered cup nut 120 by the second end 122 of tapered cup nut 120, the internal thread of attaching nut 200 coordinates with the outside thread of tapered cup nut 120, close to the first end 121 of tapered cup nut 120 gradually, the tapered wall of tapered cup nut 120 is inwardly pushed, bolt is formed to a kind of radial pressure uniformly, whole assembly is more and more fastening, until adjust to the fastening degree that user needs.Because the radial pressure in this process, bolt being produced is even, in the anti-loosening property that improves nut combinations, do not affect the fatigue strength of bolt,
Fig. 3 and Fig. 4 are respectively the locking assembled nut of controllable pressure type of the utility model preferred embodiment and be connected schematic diagram and its exploded view of bolt, comprise mother nut 100, attaching nut 200, pad 300, bolt 400.Mother nut 100 comprises hexagon nut 110 and tapered cup nut 120, and pad 300 is circular ring metal thin slice.First, pad 300 is inserted in to bolt 400 from the screw rod of bolt 400, then, the bolt with pad 300 400 is inserted to mother nut 100 from hexagon nut 110 1 sides of mother nut 200; Last attaching nut 200 is screwed into the tapered cup nut 120 of mother nut 100.Pad 300 is arranged between bolt 400 and mother nut 100, has increased load area, played sealing and fastening effect.And, in the time that attaching nut 200 is screwed into tapered cup nut 120, can cause the tapered wall of tapered cup nut 120 to the screw extruding of bolt 400, bolt is formed to uniform radial pressure, do not affect the fatigue strength of bolt and the anti-loosening property of raising assembled nut.
The locking assembled nut of controllable pressure type that the utility model proposes, when having that preparation process is simple, anti-loosing effect good and coordinating with bolt, screw thread stress distribution is even, does not affect the features such as bolt fatigue strength.
More than describe preferred embodiment of the present utility model in detail.The ordinary skill that should be appreciated that related domain just can be made many modifications and variations according to design of the present utility model without creative work.Therefore, all technician in the art comply with design of the present utility model on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment, all should be in by the determined protection domain of claims.
