Description
Technical field
The present invention relates to a kind of method that rotates when nut is fastening and riveting axle self-locking nut of belt material plate of preventing, belong to fastening piece interconnection technique field.
Background technique
At present; bolt of the prior art is when being screwed into nut; nut usually can rotate; in order to prevent that nut from rotating; after must nut being blocked with instruments such as another spanners; bolt could be tightened; this method that prevents that nut from rotating is very inconvenient for some special occasion; particularly in aviation; in the equipment fields such as space flight; with the flange type part when being fastenedly connected matrix; existing attaching nut is just very inconvenient with the method that prevents the nut rotation; and in the process of using; because the vibration that use occasion produced; effects such as impact, its nut also are easy to occur loosening; therefore phenomenons such as fatigue fracture can not satisfy the needs of use.
Summary of the invention
The objective of the invention is to, provide a kind of easy to use and have vibration proof, an anti-fatigue effect prevent the method that rotates when nut is fastening and the riveting axle self-locking nut of belt material plate, to overcome the deficiencies in the prior art.
The present invention is achieved in that a kind of method that rotates when nut is fastening that prevents of the present invention is: fix two nuts on a liner plate at least, the liner plate that then this is fixed with nut is arranged on the back side of the matrix of bolt, bolt hole on the matrix is alignd with the nut bore on the liner plate, then all bolts are all passed the bolt hole on the matrix respectively and be connected with nut thread on the liner plate respectively, can prevent that when bolt is tightened nut from rotating like this.
In said method, when being fixed on nut on the liner plate, earlier the shape fabricating of nut is become the cylindrical shape of step type, and on the periphery of the maximum outside diameter of nut, produce double wedge, on liner plate, also produce simultaneously corresponding step hole, nut is pressed in the step hole of liner plate then, the double wedge on the nut is embedded in the liner plate, nut can be fixed on the liner plate like this.
The riveting axle self-locking nut that is used for a kind of belt material plate of the inventive method is: be made up of liner plate and nut, on liner plate, be provided with at least two step holes, and a nut is installed in each step hole one, the profile of each nut is and the corresponding step shape shaft of step hole, and the step axle of nut is by the less positioning and guiding axle of point diameter, tooth axle that diameter is bigger and diameter are formed less than the closing in deformed shaft of tooth axle, on the tooth axle, be provided with double wedge, the aperture of the step hole of positioning and guiding axle and liner plate is for movingly or transition fit, the outside diameter of tooth axle is greater than the big bore dia of the step hole of liner plate, and the double wedge of tooth axle embeds in the macropore inwall of step hole into.
The profile of above-mentioned liner plate is a rectangle, is provided with through hole and opening at the middle part of liner plate.
The internal thread of above-mentioned nut is the MJ screw thread.
The tapped hole shape at the closing in deformed shaft place of above-mentioned nut and sectional shape thereof are the elliptical shape after pushing.
The material of above-mentioned liner plate is the aluminum alloy plate materials of 2A12-T4; The material of nut is the GH2132 high-temperature alloy material.
Owing to adopted technique scheme, nut of the present invention has adopted the step cylindrical form, and a circle double wedge is arranged in step cylinder outside, its internal thread adopts the MJ strengthened thread, when nut is pressed into liner plate, on nut, be provided with the positioning and guiding axle that plays location and leading role, the double wedge of nut embeds in the inwall of liner plate step macropore, this nut of the present invention and liner plate linkage structure, nut rotates in the time of can not only preventing effectively that bolt is screwed into, and can also play in work is used and reduce vibration, prevent loosening and strengthen the effect of antifatigue.Because aviation requires to have fatigue resistance with bolt, and MJ screw thread fatigue resistance is than regular screw threads height, little because of part of the present invention again, wall approaches, the cylindrical place closes up to subdue from the front and can make part deformation and change the closing in size, influence coupling mechanism force, for this reason, nut of the present invention all adopts the MJ internal thread, cooperate with corresponding outside thread, can reach the requirement of coupling mechanism force.Therefore, the present invention compared with prior art, the present invention not only has advantage easy to use, but also has bolts and nuts vibration proof and the effective advantage of antifatigue when connect using.The important connection flange type fastening piece locking, anti-rotation that the present invention is particularly suitable for equipment fields such as Aeronautics and Astronautics connects use.
