Description

Aviation ears plate nut and processing method thereof
Technical field
The present invention relates to a kind of aviation special part, particularly to a kind of aviation ears plate nut and processing method thereof.
Background technology
Ears plate nut is a kind of securing member used in military project and aviation field, and its material is rustless steel, and processing is logical Mode frequently with cold pier molding.It mainly includes main body and is located at main body both sides supporting plate integrated with main body, main Offering threaded mounting hole on body, on two supporting plates, symmetry is provided with installing hole.Owing to this securing member applies to more special ring In border, to its hardness, required higher by force intensity and antioxidation degree.But traditional ears plate nut is through for a long time After using, it is easily subject to the corrosion of external agency, time simultaneously by excessive load, is susceptible to deformation.
Summary of the invention
The deficiency existed for prior art, the invention provides a kind of anti-deformation, improves by force intensity, anticorrosion, hard Spend high aviation ears plate nut and method is put in processing.
For achieving the above object, the technical scheme is that a kind of aviation ears plate nut, include master Body and be located at main body both sides supporting plate integrated with main body, main body offers threaded mounting hole, symmetrical on two supporting plates It is provided with installing hole, it is characterised in that: it is connected by arcuation joint face between described supporting plate and main body, supporting plate and the appearance of main body On face, plating is provided with nickel dam respectively, and supporting plate is evenly equipped with some convexes on the end face relative to the other end being connected one end with main body Rise.
Using technique scheme, be connected by arcuation joint face between supporting plate with main body, in use, supporting plate is subject to To external pressure can pass to main body through arcuation joint face, thus reduce the external force extruding to supporting plate, can prevent supporting plate from existing During use occur deformation, improve supporting plate by force intensity;The setting of nickel dam can prevent main body and supporting plate from being aoxidized, with And prevent external agency from it is caused corrosion, the service life of main body and supporting plate can be extended;On supporting plate, the setting of positioning convex can Do not have displacement after making supporting plate when mounted and installing, thus ensure that aviation ears plate nut implements the firm of locking Property.
The present invention is further arranged to: the cross section of positioning convex is tapered.
Use technique scheme, good positioning effect is so set, does not haves slip.
The present invention is further set to: the inwall of the threaded mounting hole of main body is provided with anti-inversion organization, this anti-reversing Mechanism includes the arcuation groove being opened on threaded mounting hole inwall, in being gradually reduced between one end and the other end of this arcuation groove Formula is arranged, and is provided with locking steel ball in arcuation groove.
Use technique scheme, so arrange and the helical member being connected with main body can be made will not to go out after implementing locking with main body Situation about now reversing and get loose, improves steadiness.
A kind of processing method of aviation ears plate nut, it is characterised in that: step is as follows, a, by special cold pier mould Tool processes the preliminary shaped article with main body and supporting plate;B, will open in the main body of shaped article preliminary in step a and supporting plate If through hole, and through hole is carried out tapping process;C, by step b completes threaded mounting hole processing preliminary shaped article quench Fire;D, by step c completes quenching preliminary shaped article carry out surface process;E, surface treated just one-step forming is produced The outer surface nickel coating of product.
Wherein, the surface in step d is processed as surface roughness process so that it is surface roughness Ra≤0.3.
Use technique scheme, in the course of processing, preliminary shaped article is implemented quenching, improves aviation ears with this The hardness of plate nut, can prevent aviation ears plate nut from deformation in use occur;The process of surface roughness can Make the degree of adhesion between nickel dam and aviation ears plate nut be improved, enable stable plated of nickel dam to be located at aviation ears On plate nut, thus preferably play antioxidation and etch-proof effect.
The invention will be further described below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
A kind of aviation ears plate nut as shown in Figure 1, include main body 1 and be located at main body 1 both sides and with main body one Body formed supporting plate 2, main body 1 offers threaded mounting hole 11, and on two supporting plates 2, symmetry is provided with installing hole 21, supporting plate 2 and master Being connected by arcuation joint face 3 between body 1, on the outer surface of supporting plate 2 and main body 1, plating is provided with nickel dam 4 respectively, supporting plate 2 relative to Some positioning convex 22 it are evenly equipped with on the end face of the other end being connected one end with main body 1.In such scheme, supporting plate 2 and main body 1 it Between be connected by arcuation joint face 3, in use, the external pressure that supporting plate 2 is subject to can pass to through arcuation joint face 3 Main body 1, thus reduce the external force extruding to supporting plate 2, can prevent supporting plate 2 from deformation in use occurring, improve supporting plate 2 By force intensity;The setting of nickel dam 4 can prevent main body 1 and supporting plate 2 from being aoxidized, and prevents external agency from it is caused corrosion, Main body 1 and the service life of supporting plate 2 can be extended;On supporting plate 2, the setting of positioning convex 22 can make supporting plate 2 when mounted and install After do not have a displacement, thus ensure that aviation ears plate nut implements the steadiness of locking.
In embodiments of the present invention, in order to keep more entering one after making supporting plate 2 when mounted and installing and between attached body Fixing of step, the cross section of positioning convex 22 is tapered.Certainly, it should be noted that positioning convex 22 also can arcuation or triangle Shape, is all feasible.
In order to make the helical member being connected with main body 1 not have reversing and situation about getting loose after implementing locking with main body 1, carry High-stability.The inwall of the threaded mounting hole 11 of main body 1 is provided with anti-inversion organization 5, and this anti-inversion organization 5 includes and is opened in Arcuation groove 51 on threaded mounting hole 11 inwall, in being gradually reduced formula setting between one end and the other end of this arcuation groove 51, and Locking steel ball 52 it is provided with in arcuation groove 51.
The processing method that the invention provides a kind of aviation ears plate nut, step is as follows, a, by special cold pier Mould processes the preliminary shaped article with main body 1 and supporting plate 2;B, by the main body 1 of shaped article preliminary in step a and supporting plate Offer through hole on 2, and through hole is carried out tapping process;C, will step b complete threaded mounting hole processing preliminary shaped article Quench;D, by step c completes quenching preliminary shaped article carry out surface process;E, to surface treated tentatively The outer surface nickel coating of shaped article.Wherein, the surface in step d is processed as surface roughness process so that it is surface roughness Ra≤0.3.In the course of processing, preliminary shaped article is implemented quenching, improves the hardness of aviation ears plate nut with this, can Prevent aviation ears plate nut from deformation in use occurring;The process of surface roughness can make nickel dam and aviation ears torr Degree of adhesion between crab bolt is improved, and enables stable plated of nickel dam to be located on aviation ears plate nut, thus more Good plays antioxidation and etch-proof effect.
