Abstract
The utility model provides a seat circle of fixed self -locking nut, a serial communication port, including support (1) and spacing area (2), open at the support center has the through -hole, the left and right sides is equipped with baffle (1 -1) respectively on the support, it has partial ring channel (1 -2) to open on the baffle, spacing area is placed in partial ring channel and is connected two baffles, the front end in spacing area space between the baffle forms blend stop (2 -1), the rear end in spacing area space between the baffle forms separation blade (2 -2), the self -locking nut can be followed the separation blade position and slideeed in between the baffle, the baffle removes about preventing the self -locking nut, blend stop and separation blade cooperation prevent the self -locking nut back -and -forth movement and reciprocate.
Description
Technical field
This patent belongs to aviation mechanical connection standard piece field, is mainly applicable to the basic union piece that aircaft configuration connects.
Background technique
Seat ring is applicable to the connection of air line basic structure, has detachable performance good, easy for installation, and mounting type is by fixing structurally with the interference of structure hole.Seat ring and self-locking nut support the use the number of openings that can reduce on aircaft configuration, substantially increase the fatigue life of structure.Self-locking nut is step-like, bottom with two auricles, see accompanying drawing 1.A lot of position does not allow structurally riveter nail aboard, to avoid having an impact to the fatigue strength life-span of this structure, the use of existing aircraft major part is the supporting plate self-lock nut of fixed structure, and nut is integrated by being riveted on housing construction, then realizes connecting with bolt fixed sandwich.Seat ring is fixed in structural beams by interference fit, is then snapped on seat ring by the spacing band on seat ring by supporting nut.
Summary of the invention
The purpose of this utility model is for requiring in aircraft link that quality of fit is high, thickness of interlayer large, having the structure changed and require, connect for one side, and during solution plate nut uses, installation requirement is high, changes the problem of difficulty.Thus the requirement improving maintainability performance under the prerequisite meeting anatomical connectivity, reduce mounting process to a certain extent.This seat ring and matching nut can be widely used in aircaft configuration and be connected, and are especially applicable in the connection of large gauge fastening piece.By seat ring and nut being supported the use the object meeting nut and change and conveniently install, meet the needs that aircraft fastening piece connects operation and maintenance.
A kind of seat ring of fixing self-locking nut, it is characterized in that, comprise bearing (1) and spacing band (2), bearing center has through hole, on bearing, the left and right sides is respectively equipped with baffle plate (1-1), baffle plate has part circular groove (1-2), spacing band to be placed in part circular groove and to connect two baffle plates, the front end in spacing band space between baffle plate forms blend stop (2-1), the rear end in spacing band space between baffle plate forms catch (2-2), self-locking nut can slip between baffle plate from catch position, baffle plate prevents self-locking nut from moving left and right, blend stop and catch cooperation prevent self-locking nut from moving forward and backward and moving up and down.
Bearing (1) part is on the one hand for being fixed to linkage structure, the matching used nut with this seat ring is blocked on the other hand by spacing band, the free movement controlling supporting self-locking nut ensures that basal body of nut can not from bracket from pulling away in installation process simultaneously, ensure the position of self-locking nut in installation process, the opening direction of bearing take into account bearing to be connected on the impact that matching nut is installed after in structure, thus realize supporting accessible dismounting.
Further, spacing band has elasticity.
The utility model is by adjustment mounting type, make self-locking nut self-adapting adjusted positions supporting with it, substantially increase the efficiency and assembly quality that are threaded, reduce because the impact changed and bring structure safeguarded by self-locking nut, be applicable to highi degree of accuracy, heavy parting mechanism and more being threaded of maintenance times, effectively can solve during existing nut is installed the problem that the maintainability existed is poor, install difficulty.Higher to the requirement of installing space in aircaft configuration, limit the means of operation and maintenance, change self-locking nut is serious problems on the impact that housing construction causes simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of self-locking nut;
Fig. 2 the utility model structural representation;
Fig. 3 the utility model using state schematic diagram.
Embodiment
Seat ring is made up of (see Fig. 2 and Fig. 3) spacing band and bearing two-part, bearing center has through hole, on bearing, the left and right sides is respectively equipped with baffle plate 1-1, baffle plate has part circular groove 1-2, spacing band to be placed in part circular groove and to connect two baffle plates, the front end in spacing band space between baffle plate forms blend stop 2-1, and the rear end in spacing band space between baffle plate forms catch 2-2, and self-locking nut can slip between baffle plate from catch position.
Be installed to by spacing band on the part circular groove 1-2 of bearing 1 in installation process, bearing 1 is fixed in structure by interference fit.Supporting self-locking nut is according to the direction of spacing band opening, namely catch position slides between the baffle plate 1-1 of bearing, catch 2-2 is firmly forced to deform, resiled by catch 2-2 after catch 2-2, matching nut is fixed on bearing by blend stop 2-1 and catch 2-2, during installation, support has the free movement of 0.5mm for regulating the axial position with bolt.Unloading process is that matching nut is released bearing 1, and matching nut is skidded off from bearing 1 opening direction, by forcing spacing band to be out of shape, skidding off bearing 1, taking out used nut.Then according to the method for mounting nuts, new nut being slipped over spacing band is installed on support, realizes the replacing of nut.
Claims (2)
1. the seat ring of a fixing self-locking nut, it is characterized in that, comprise bearing (1) and spacing band (2), bearing center has through hole, on bearing, the left and right sides is respectively equipped with baffle plate (1-1), baffle plate has part circular groove (1-2), spacing band to be placed in part circular groove and to connect two baffle plates, the front end in spacing band space between baffle plate forms blend stop (2-1), the rear end in spacing band space between baffle plate forms catch (2-2), self-locking nut can slip between baffle plate from catch position, baffle plate prevents self-locking nut from moving left and right, blend stop and catch cooperation prevent self-locking nut from moving forward and backward and moving up and down.
2. the seat ring of fixing self-locking nut according to claim 1, is characterized in that, spacing band (2) has elasticity.
