Description
Technical field
The utility model relates to a kind of assembly that is fastenedly connected, and particularly relates to a kind of barrel-shaped floating self-locking nut connection part.
Background technique
In airplane parts design, some influences the plug-in of the tired key component of aircraft flight safety or the setting of casing position, and generally all requiring provides plug-in connection at these tired key positions.Especially the high-temperature and high-stress zone that influences fatigue life is adopted the structural fatigue design criterion not allow and is threaded, and plain nut performance under the high-temperature and high-stress condition is difficult to guarantee, aircraft is existed not have the potential safety hazard of fixing a number.If then there is problems such as being difficult to the sealing installation in hanging joint outside the design of casing position.If adopt the outer hanging joint of traditional shoulder shaft type, problem such as maintainability is poor, can't install and remove again, and weight is big assembly precision requirement height then can appear.In civilian industry, bigger in order to solve thickness, connection between the supporting member, the most frequently used method is exactly that bolton connects, and is though such link is simple in structure, reliable and stable, but link for needs dismounting and maintenance, its deficiency is the dismounting trouble, safeguards inconvenience, and inefficiency.
Summary of the invention
The purpose of this utility model is, a kind of barrel-shaped floating self-locking nut connection part is provided.To improve the anti-fatigue performance of housing construction, solve the problem that the monolateral casing of aircraft has the sealing of store mounting point and alleviates structure weight, overcome the prior art above shortcomings.The utility model can reduce the manufacture difficulty of carrying junctor member, again can weight reduction, and the safety reliability height, easy to maintenance.
The technical solution of the utility model: a kind of barrel-shaped floating self-locking nut connection part, comprise nut seat, nut seat is provided with self-locking nut, and nut seat is connected with the self-locking nut via pins.
In the aforementioned barrel-shaped floating self-locking nut connection part, described self-locking nut comprises nut body and screw boss, and nut body is provided with the nut pin-and-hole; The screw boss is provided with tapped through hole; The opening of tapped through hole is provided with 1～4 closing in.
In the aforementioned barrel-shaped floating self-locking nut connection part, described nut body is that concave circular arc is connected with the joint of screw boss.
In the aforementioned barrel-shaped floating self-locking nut connection part, described nut body be shaped as the two tangent plane bodies of cylindrical body along the parallel axes direction; Two relative sides of two tangent plane bodies are respectively flat side and arc side; Be respectively equipped with a nut pin-and-hole on two flat sides.
In the aforementioned barrel-shaped floating self-locking nut connection part, the diagonal angle setting on two flat sides of described two nut pin-and-holes.
In the aforementioned barrel-shaped floating self-locking nut connection part, described nut seat be shaped as and form self-locking nut with the cylindrical body of diameter uniplanar body along the parallel axes direction; The tangent plane of uniplanar body be provided with self-locking nut on the corresponding through hole of tapped through hole; The two ends of uniplanar body are provided with baffle plate, and baffle plate is provided with and the corresponding seat pin of nut pin-and-hole hole, and the aperture in seat pin hole is less than the aperture of nut pin-and-hole, and equal the diameter of pin.
In the aforementioned barrel-shaped floating self-locking nut connection part, described baffle plate is provided with U-groove bevel.
In the aforementioned barrel-shaped floating self-locking nut connection part, the clearance distance between described two baffle plates is greater than the distance between the flat side on the self-locking nut.
In the aforementioned barrel-shaped floating self-locking nut connection part, the distance of the center of described self-locking nut upper cap nut pin-and-hole to self-locking nut bottom plane is less than the distance in center to the tangent plane of nut seat seat of honour pin-and-hole.
In the aforementioned barrel-shaped floating self-locking nut connection part, the tubular that is shaped as coil sheet 2～4 circle formation of described pin.
Compared with prior art, self-locking nut of the present utility model can have on the tangent plane of nut seat and a certain amount ofly floats or move about.The cylndrical surface of nut seat is identical with self-locking nut two cambered surface diameters, during assembling, because the distance of center to the self-locking nut bottom plane of self-locking nut upper cap nut pin-and-hole is less than the center of the nut seat seat of honour pin-and-hole distance to the tangent plane platform.Make the center of circle between self-locking nut two cambered surfaces can make progress translation one segment distance so that can float, therefore self-locking nut of the present utility model can insert the band of position that should assemble quickly and easily, and this zone is a high stress areas; Because the spacing on the nut seat between two baffle plates is greater than the distance between two planes on the self-locking nut.The nut pin bore dia that adds the seat pin boring ratio self-locking nut on the nut seat is little, and the pin external diameter is identical with the seat pin hole on the nut seat, the promptly solid alternative plate nut that moves about.1～4 closing on the boss on the self-locking nut realizes auto-lock function.On nut seat, open the quality that U-groove bevel can alleviate whole assembly.Pin selects for use light sheet to be rolled into circle, plays the function of elastic cylindrical pin, and is for convenience detach when replacing assembly, also can alleviate the quality of whole assembly simultaneously.The utility model is selected the surface treatment of the light metal material and the high temperature high voltage resistant of high temperature high voltage resistant for use, selects for use common material to be applied to the normal temperature zone, selects for use some nonmetallic material to make also can be applied to some nonmetallic software to be fastenedly connected.The utility model has improved the anti-fatigue performance of connection part owing to taked above technological scheme, has solved the problem that the monolateral casing of aircraft has the sealing of store mounting point and alleviates structure weight, overcomes the deficiency that prior art exists.The utility model can reduce the manufacture difficulty of carrying junctor member, again can weight reduction, and the safety reliability height, easy to maintenance.
