Whether step S32, observation common rail bonnet move to 14 center of boss；
Step S33 is back to step S32 if observation result is yes, if observation result is no, closes motor 13, into
Enter next step.
In embodiments of the present invention, it executes with step S12 before step S1 is executed and also needs to execute detecting step, inspection later
Surveying step includes：
Common rail bonnet is placed in fumarole 16 by step S13, is injected gasoline from common rail bonnet oil outlet, is used detection bar
Common rail bonnet oil outlet is withstood in 18 bottoms, opens jet switch 17, observe common rail bonnet oil outlet whether oil spout；
Step S14, into repair step, if it is judged that being no, terminates repair if observation result is yes.
The present invention operation principle be：When using the common rail bonnet maintenance unit, common rail bonnet is placed on fumarole 16
It is interior, to common rail bonnet oil outlet at inject gasoline, withstand common rail bonnet oil outlet with 18 bottom of detection bar, open jet switch
17, gas pours into fumarole 16, since 18 bottom of detection bar matches with common rail bonnet oil outlet, if common rail bonnet oil outlet
There is abrasion at place, then oil outlet cannot be fully sealed, and under the influence of air pressure, is able to observe that gasoline sprays together with gas,
Illustrate there is abrasion at oil outlet, and at oil outlet wear it is more serious, gasoline spray the phenomenon that it is more apparent；There to be the common rail of abrasion
Bonnet takes out, and is placed on microscope after cleaning wiping, observes common rail bonnet oil outlet wear condition, determine cutting depth；It will
Common rail valve cap head end surface is contacted with boss 14, and due to being equipped with magnet in boss 14, common rail bonnet is pull-in on boss 14, this
When open 13 reversal switch of motor, so that motor 13 is inverted, due at common rail bonnet oil outlet in conical surface shape, when common rail bonnet
When not completing positioning, milling cutter 8 constantly contacts the oil outlet conical surface in rotation process, drives common rail bonnet constantly into boss 14
The heart moves, and when common rail bonnet no longer moves, position fixing process is completed, and motor 13 is common rail in order to prevent using the purpose of reversion
Bonnet milling cutter 8 in position fixing process wears the oil outlet conical surface, influences to repair；After the completion of position fixing process, motor 13 is closed, opens and drives
Dynamic device 9, mandril 15 move right under the action of driving force, complete the fixation to common rail bonnet；Synchronizing wheel 10 is slided to the right
Dynamic, since synchronizing wheel 10 and milling cutter 8 are fixed by jackscrew, milling cutter 8 and then slides to the right, opens motor 13 and rotates forward switch, makes motor
13 rotate forward, and prepare to common rail bonnet trial cut；The vernier knob of rotating electron micrometer, milling cutter 8 delay under the drive of micrometric screw
Slowly it moves downward, when feeling that the resistance of rotary fine adjustment knob becomes larger suddenly, illustrates that 8 point of a knife of milling cutter is contacted with common rail bonnet,
Stop rotating vernier knob, and electronic microcalliper is returned to zero, and milling reference plane determines, trial cut process terminates；Continue rotating electron thousand
The vernier knob of ruler, milling cutter 8 is divided to start milling work, observe electronic microcalliper registration, the registration of electronic microcalliper is at this time
The distance that milling cutter 8 is advanced to the left from milling reference plane, when electronic microcalliper registration is equal to cutting depth, fine tuning rotation of stopping rotating
Button closes motor 13, closes driving device 9, and mandril 15 is moved downward to original position, removes common rail bonnet and in common rail bonnet
Milling clast is cleared up, and is then repaired to common rail bonnet with filler material；The common rail for completing repair is placed again into jet
It is detected in hole 16, repeats the above steps if detection is unqualified, until common rail bonnet detects qualified, end repair.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
From the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended power
