Abstract
The utility model provides a self-locking nut without a lug supporting board. The self-locking nut without the lug supporting board is a hollow cylinder with the two ends opened, an inner cavity of the cylinder is a stepped hole, the inner diameter of the middle section of the cylinder is greater than that of the two ends of the cylinder, one end of the cylinder is an oval end face, the oval end face and the outer wall of the cylinder are in transition through a circular cone, and an inner thread is arranged on the wall of the inner cavity of the other end of the cylinder. The self-locking nut without the lug supporting board simplifies the structure of a nut with a lug supporting board, and eliminates a traditional rivet connection mode. The self-locking nut without the lug supporting board is convenient to install, and improves the fatigue strength of the assembly portion of a connection piece. The self-locking nut without the lug supporting board not only improves the installation speed and the reliability and is suitable for interlayers with different materials and sizes, but also is light in weight and compact in designed structure, the production cost is reduced and products can be replaced quickly.
Description
Technical field
The present invention relates to a kind of Novel fastening and connect the self-locking nut structure, can replace traditional ear supporting plate self-locking connecting means that has, belong to sheet material interconnection technique field.
Background technique
At present, when aircraft needs sheet material to connect, generally adopt the mode that has the ear supporting plate self-lock nut to connect, when adopting the method to connect, need to bore 3 mounting holes, one is bolt through-hole, and other 2 is the installation fixed hole that the ear plate nut is arranged, needing will have the ear supporting plate to be connected with interlayer by rivet, and the ear plate nut is fixed on aircraft structure.The tool kind that this means of fixation not only needs when mounted is more, and inconvenience is installed, and requires great effort consuming time.In addition, the risk that the existence of rivet hole has brought aircraft structure to crack causes structural member to produce tired.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of earless supporting plate self-lock nut, compact structure, lightweight, easily install, can replace traditional ear plate nut that has, to satisfy the requirement that on aircraft, interlayer is fastenedly connected, improve installation rate and reliability, alleviate aircraft weight, enlarge the using scope of product, be fit to the use of the link of different size, different materials.
The technical solution adopted for the present invention to solve the technical problems is: described earless supporting plate self-lock nut is the hollow circular cylinder of both ends open, and cylindrical inner chamber is step hole, and the stage casing internal diameter is greater than the internal diameter at two ends; Cylindrical body one end is oval end face, by the circular cone transition, has internal thread on the internal chamber wall of the other end between end face and cylindrical body outer wall.
Described cylindrical body outer wall is Step Shaft, has the external diameter of internal thread one end less than the other end.
Described cylindrical cavity has chamfering at the two ends that have internal thread one end and large diameter section.
The large diameter section in described internal thread and cylindrical body stage casing is not joined.
Described internal thread adopts screw thread to close up and realizes screw thread self-locking.
The invention has the beneficial effects as follows: the present invention has simplified ear plate nut structure, and unique structural design has been cancelled traditional rivet Placement.The present invention is easy for installation, improves the fatigue strength at link assembling position.Use of the present invention has not only improved installation rate and reliability, is applicable to the interlayer of different materials and size, and the present invention is lightweight, and project organization is compact, has reduced cost of production, the product fast changeable.

Embodiment
The present invention is further described below in conjunction with drawings and Examples.
As shown in Figure 1, earless supporting plate self-lock nut of the present invention is the hollow circular cylinder of both ends open, and cylindrical inner chamber is step hole, and the stage casing internal diameter is greater than the internal diameter at two ends, as texturing zone 2; Cylindrical body one end is oval end face, by the circular cone transition, consists of oval capitiform 1 between end face and cylindrical body outer wall, has internal thread on the internal chamber wall of the other end, as locking screw 3.
Described cylindrical body outer wall is Step Shaft, has the external diameter of internal thread one end less than the other end.
Described cylindrical cavity has chamfering at the two ends that have internal thread one end and large diameter section.
The large diameter section in described internal thread and cylindrical body stage casing is not joined.
Described internal thread adopts screw thread to close up and realizes screw thread self-locking.
As shown in Figure 2, earless supporting plate self-lock nut of the present invention can also be the hollow circular cylinder of an end opening, and cylindrical inner chamber is step hole, and the stage casing internal diameter is greater than the internal diameter at two ends, as texturing zone 2; Cylindrical body opening one end is oval end face, by the circular cone transition, consists of oval capitiform 1 between end face and cylindrical body outer wall, has internal thread on the internal chamber wall of sealing one end, as locking screw 3.
Comprise the following steps when as shown in Figure 3, the present invention uses:
[1] through hole is installed in processing on link 4 and interlayer 5;
[2] through hole of link 4 carried out spot-facing;
[3] draw rifle to tighten up the plug insertion;
[4] utilize the fixing piece that earless plate nut 6 is enclosed within (nut tack is towards drawing rifle) on plug;
[5] plug is screwed into the self-locking area (nut screws in 3 buttons half at least) of helical thread portion;
[6] adjust the position of top cover;
[7] with the locking nut locking top cover position of drawing on rifle;
[8] nut is inserted in mounting hole;
[9] plug is screwed out from nut, namely install.
The whole earless structural design that adopts of self-locking nut of the present invention, the nut head is ellipsoidal structure, this structure can play spacing effect to a certain extent, the nut bottom is the worm structure for locking, two ends connect by middle texturing zone, the texturing zone intracavity diameter is greater than the diameter of other position inner chamber of nut, the compressed distortion in texturing zone during staking.The present invention has simplified ear plate nut structure, and unique structural design has been cancelled traditional rivet Placement.Easy for installation, improve the fatigue strength at link assembling position.
