Above-mentioned drawing robs 5 with the cavity that can accommodate extruding plug 2, has and drives extruding 2 guide end 21 of plug to drawing rifle 5
The mobile driving device in inside, there is top cap to install interface 51, have plug and apical axis installation interface 52.
The installation method of novel interference bush is as follows：When installing bushing 1, the bushing that bushing 1 is first put into clearance fit is pacified
Hole is filled, 2 guide end 21 of plug will be squeezed and pass through bushing 1,2 guide end 21 of extruding plug is mounted on to draw and rob on 5, in bushing 1 and draws
Installation top cap 3 is additionally provided between robbing 5；Start and rifle 5 is drawn so that squeeze 2 working end 22 of plug passes through from 1 inner wall of bushing, utilizes
Bushing 1 is fixed on bushing mounting holes by higher and suitable interference volume.
Method for dismounting is as follows：When dismantling bushing 1, dismounting 6 guide end 61 of apical axis is first passed through into bushing 1, dismounting apical axis 6
Guide end 61 is mounted on to draw and rob on 5, and dismounting top cap 7 is additionally provided between bushing 1 and drawing rob 5；Start and draw rifle 5 so that dismounting is used
6 working end 62 of apical axis is released by bushing 1 from bushing mounting holes.
The present invention can effectively reduce bushing installation difficulty and set-up time, improve bushing installation quality and precision, prevent from serving as a contrast
Set is deviate from from crossing point holes, preferably protects key structure；Bushing damage need replacing when, reduce dismounting difficulty, reduce or
It eliminates hole wall to scratch, squeezes plug during to bushing coining, it is opposing stationary between bushing and bushing mounting holes, without position
It moves, the damage that bushing generates bushing mounting holes is minimum, has the mode of displacement relative to tradition, has great effect.Together
When, on the one hand the installation method of novel interference bush realizes hole edge buttressing effect by interference fit, reduce stress amplitude, another
Aspect obtains hole edge plastic deformation by using suitable interference volume, reduces stress level, and the anti-tired of structure is improved in terms of two
Labor quality.
