Background technique
Aircraft gun is one of composition of aircraft weapon system, because of the advantages that its fire accuracy is high, firing rate is high, and ammunition quantity is big,
It is widely assemblied on fighter plane, attack plane, bomber and armed helicopter, to complete air to air and Air-to-Ground Warfare.
Usually there are three types of forms for the installation of aircraft gun aboard: inside fixed installation, plug-in gun pod and flexible turret
Installation, wherein plug-in gun pod is because be suspended on external fuselage, by aerodynamic loading, itself weight in aircraft flight
The powerful recoil that is also easy to produce when amount, flight overload and shooting, suffered load condition is complicated and load is larger, thus to body
Connection proposes higher requirement.
Summary of the invention
Technical problem solved by the invention is to provide a kind of aircraft gun pod seat structure, to solve above-mentioned background
Disadvantage in technology.
Technical problem solved by the invention is realized using following technical scheme:
A kind of aircraft gun pod seat structure, including aircraft gun pedestal, wherein aircraft gun pedestal passes through fastener and body knot
Structure mechanical connection, the load that gun pod transmits is diffused on aircraft load-carrying member, and indentation has bushing inside aircraft gun pedestal, is served as a contrast
Set top is provided with for the internal screw thread and external screw thread for connecting with nut with blocking connection, blocking for prevent bushing because
Institute is loaded excessive and causes to deform, and then falls off from aircraft gun pedestal, and nut is for bearing longitudinal loading；And bushing top and boat
By cylindrical surface clearance fit, bushing lower part is bonded with aircraft gun pedestal by circular conical surface gun platform body.
In the present invention, it is provided with locating slot on aircraft gun pedestal, and is provided with and determines on bushing corresponding with this locating slot
Position pin hole, the positioning pin for fixing aircraft gun pedestal and bushing are inserted into locating slot and dowel hole.
In the present invention, insurance hole is had on nut and aircraft gun pedestal, it is locking using fuse.
In the present invention, the cylindrical surface on bushing top is provided with boss, for bushing to be pressed into aircraft gun pedestal.
In the present invention, first bushing is pressed into aircraft gun pedestal when assembling, after being pressed into bushing, by the dowel hole of bushing
Be aligned with the locating slot of aircraft gun pedestal, be inserted into positioning pin, the internal screw thread for being screwed into bushing will blocked, after nut is screwed into bushing
External screw thread, and by the insurance hole of fuse insertion nut and aircraft gun pedestal, assembled assembly parts are finally being passed through into fastening
Part is connect with housing construction.
The utility model has the advantages that the present invention arranges plug-in gun pod support in body, provided for plug-in gun pod a kind of logical
It with, reliable connection, while can be used for the connection of other store Combinations of aircraft, effectively improve the plug-in interchangeability of aircraft, expand and fly
The purposes of machine, to improve the utilization rate of aircraft.

Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, tie below
Conjunction is specifically illustrating, and the present invention is further explained.
Referring to a kind of aircraft gun pod seat structure of FIG. 1 to FIG. 5, including aircraft gun pedestal 1, bushing 2, nut 3, blocking
4 and positioning pin 5, aircraft gun pedestal 1 is mechanically connected by bolt and rivet and housing construction, the load for transmitting gun pod
It is diffused on aircraft load-carrying member, bushing 2 is pressed into inside aircraft gun pedestal 1, and 2 lower part of bushing and aircraft gun pedestal 1 pass through circular cone face paste
It closes, for bearing course load and transverse load, 2 top of bushing and aircraft gun pedestal 1 pass through cylindrical surface clearance fit, and in bushing
2 tops are provided with internal screw thread and external screw thread, and internal screw thread is connect with blocking 4, prevent from causing bushing 2 to become because institute is loaded excessive
Shape, so that bushing 2 be caused to fall off from aircraft gun pedestal 1, external screw thread is connect with nut 3, for bearing longitudinal loading.Positioning pin 5 is inserted
In the dowel hole for entering bushing 2, for positioning bushing 2, prevent bushing 2 from rotating；It is provided on nut 3 and aircraft gun pedestal 1 simultaneously
Insurance hole, it is locking using fuse.
In the present embodiment, first bushing 2 is pressed into aircraft gun pedestal 1 when assembling, in order to guarantee installation accuracy, such as Fig. 1, figure
Shown in 2, significant dimensions at 3 are shared on aircraft gun pedestal 1 and bushing 2, the cooperation including cylindrical surface requires, the cooperation of circular conical surface requires
And surface roughness requirements；After being pressed into bushing 2, dowel hole on bushing 2 is aligned with locating slot on aircraft gun pedestal 1, is inserted into
Positioning pin 5 will block 4 internal screw threads for being screwed into bushing 2, after nut 3 is screwed into the external screw thread of bushing 2, nut 3 and aircraft gun pedestal
Insurance hole is provided on 1, it is locking by fuse；Institute's complexity loaded when recoil is big when because of aircraft gun transmitting and flight, therefore this
All part materials select 30CrMnSiA material to be made in embodiment；Assembled assembly parts are finally being passed through into fastener
