Step one, part thickness and installing hole aperture are processed according to aviation spherical bearing thickness, outside dimension, install
At aperture, upper and lower two ends, hole, chamfer dimesion is processed according to difference size on the upper side；Installing hole small-gap suture by aviation spherical bearing Yu part
Cooperation fits together；
Step 2, lower mold tire 1 is fixed on forcing press platform；Upper mold tire 2 taper shank part is installed to principal axis of pressing machine
Upper fixing；
Step 3, mandrel 3 one end are fixed in the center positioning hole of lower mold tire 1, and mandrel 3 passes the bearing equipped with part,
The center positioning hole of upper mold tire 2 and the other end matched in clearance of mandrel 3, mandrel 3, lower mold tire 1 and upper mold tire 2 are coaxial；Two mould tires
Flange sword match with the V-groove of the outer ring both ends of the surface of bearing and contact；
Step 4, being uniformly downwardly applied to pressure extrusion upper mold tire by principal axis of pressing machine, flange sword outer surface makes outside V-groove
There is plastic deformation flange in surface, fits tightly fixing with the chamfering of inner bore of part；Until pressure loading stops after reaching setting value
Only pressure；
After step 5, bearing stamping flange have assembled, the ultimate value of bearing load is to aviation spherical bearing as requested
Axially two sides is detected respectively, it is ensured that bearing does not occur relative movement under ordinance load with part, and bearing rotary is normally
It is believed that realize flange assembling.
Beneficial effect: the assembly tool simple in construction of the present invention, easy to operate, usual pressure lathe can be achieved with zero
Part and the punching press flange assembly work of aviation spherical bearing, do not use special equipment, and assembly yield is high, to aviation spherical bearing
And piece surface destructiveness is little, reliable in quality, good looking appearance.

Detailed description of the invention
For making the purpose of the present invention, content and advantage clearer, the detailed description of the invention of the present invention is made the most in detail
Thin description.
As it is shown in figure 1, the present invention provides the assembly tool of a kind of aviation spherical bearing, mainly by lower mold tire 1, upper mold tire 2
Form with mandrel 3, with the revolving body of positioning shaft hole centered by lower mold tire 1 and upper mold tire 2；The diameter of mandrel 3 and spherical bearing
Diameter of bore, the centralized positioning shaft hole diameter of upper and lower mould tire match, the lower end of mandrel 3 and lower mold tire 1 interference fit, core
The upper end of axle 3 and upper mold tire 2 matched in clearance, as in figure 2 it is shown, the relative one end of two mould tires is symmetrically arranged with the flange of special angle
Sword, matches with the notch (V-groove) of the outer ring both ends of the surface of bearing and contacts；In notch on flange sword inner surface and bearing outer ring
Fitting completely in surface, the angle of flange sword is more than the angle of V-groove, the inner surface of flange sword not contact bearing inner ring.This mandrel
Act primarily as location and guide effect；The external diameter of bearing 5 coordinates assembling with the installing hole small-gap suture of part 4.
As it is shown on figure 3, the assembly method of a kind of aviation spherical bearing, it is characterised in that comprise the following steps:
1) part 4 thickness and installing hole aperture are joined according to Js6 and tolerance range according to aviation spherical bearing thickness, outside dimension
Closing processing, at aperture, installing hole upper and lower two ends, chamfer dimesion is processed according to difference size on the upper side, then by aviation spherical bearing and zero
The installing hole small-gap suture cooperation of part 4 fits together；
2) lower mold tire 1 it is installed on forcing press platform and fixes；Upper mold tire 2 taper shank part is installed to principal axis of pressing machine
Upper fixing；
3) mandrel 3 one end is fixed in the center positioning hole of lower mold tire 1, interference fit, and the bearing equipped with part passes core
The other end matched in clearance of axle 3, the center positioning hole of upper mold tire 2 and mandrel 3, it is ensured that mandrel 3, lower mold tire 1 and upper mold tire 2 are same
Axle；One end that two mould tires are relative is symmetrically arranged with the flange sword of special angle, with the notch (V-groove) of the outer ring both ends of the surface of bearing
Match contact；Flange sword inner surface is fitted completely with the notch inner surface on bearing outer ring, and the angle of flange sword is more than notch
Angle；
4) setting requires force value, is uniformly downwardly applied to pressure by press machine tool main shaft and carries out flange, by extruding
Mould tire, flange sword outer surface makes notch outer surface generation plastic deformation flange, fits tightly fixing with the chamfering of inner bore of part.Turn over
The inner surface of limit sword not contact bearing inner ring.Until pressure loading stops pressure after reaching setting value, should slowly apply during pressure
Thrust, must not use impulsive force.
5) after bearing stamping flange has assembled, the ultimate value of bearing load axial to aviation spherical bearing two as requested
Face is detected respectively, it is ensured that bearing does not occur relative movement with part 4 under ordinance load, bearing rotary normally i.e. it is believed that
Realize flange assembly work.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For Yuan, on the premise of without departing from the technology of the present invention principle, it is also possible to make some improvement and deformation, these improve and deformation
Also should be regarded as protection scope of the present invention.
