Abstract
Sprayer copper sheathing extractor belongs to the engine service tool field, and include the screw tap, draw portion and uide bushing, screw tap one end be equipped with the rubber buffer, the portion of drawing establishes the other end at the screw tap, the screw tap is worn to establish in the axle center of uide bushing downtheholely. The rubber buffer can be for tip rubber tapered plug down. During the use, insert the copper sheathing with the screw tap in, the rubber buffer of screw tap tip setting this moment can seal the nozzle opening of sprayer to prevent that the piece that the operation in -process produced from getting into the engine, the rubber buffer plays the protective action. Revolve after that and twist the interior certain degree of depth of its screw in copper sheathing of screw tap messenger, then just can take out screw tap and copper sheathing together to lifting the portion of drawing. When using the copper sheathing of this patent in with engine injector and extracting, the operation intensity of labour reduce, and engine injector maintenance efficiency is being shown to be improved.
Description
Technical field
The utility model is related to engine maintenance field of tool, and in particular to be for by engine in maintenance process
The copper bush of fuel injector extractor that copper sheathing in fuel injector is extracted.
Background technology
Copper bush of fuel injector is a kind of copper cylinder being embedded on Diesel engine cylinder head, and its major function is to separate to start
The directly contact of coolant in machine fuel injector and cylinder head, for lowering the temperature and preventing water seepage.Therefore it is combined very between cylinder head
Closely, thus can increased difficulty to dismounting, because not appearing thereon, under do not connect tail, engine fuel injector copper sheathing is once occur
Fracture, needs to take out and changes.
Existing maintenance technique, is usually used Oil atomizer puller and takes out copper sheathing, but be not every time can smoothly success
Take out, especially copper bush of fuel injector fracture position is on the lower side, and Oil atomizer puller cannot take out at all, can only take dismounting engine air
The method of cylinder cap changes copper bush of fuel injector.So existing copper bush of fuel injector takes out technology has that poor reliability, efficiency is low, work
The big defect of intensity.
Utility model content
For current copper bush of fuel injector take out engineering reliability it is poor, efficiency is low, high labor intensive defect, the utility model
There is provided a kind of copper bush of fuel injector extractor.
The technical scheme in the invention for solving the technical problem is：
A kind of copper bush of fuel injector extractor, including screw tap, drawing portion and fairlead；Described screw tap one end is provided with rubber
Plug, the drawing portion is arranged on the other end of screw tap, and the screw tap is located in the axle center hole of fairlead.
When using, screw tap is located in the axle center hole of fairlead, and in lower end insertion copper sheathing, now screw tap end is arranged
Rubber stopper can seal up the nozzle opening of fuel injector, to prevent operation process in produce chip enter engine, rubber stopper is played
Protective action.Then screwing screw tap makes it screw in certain depth in copper sheathing, lift then up drawing portion just can by screw tap and
Copper sheathing takes out together.
Preferably, the rubber stopper is small end rubber tapered plug directed downwardly.
Preferably, the drawing portion includes guide rod and operation dish, and the end of the guide rod is provided with annular protrusion, the operation
Disk is sleeved on guide rod with movable connection method.
The beneficial effects of the utility model are：When using the art of this patent is extracted the copper sheathing in engine fuel injector, behaviour
Make labour intensity reduction, engine fuel injector maintenance efficiency is significantly improved.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1 rubber tapered plug, 2 screw taps, 3 fairleads, 4 drawing portions
Specific embodiment
Structure, ratio, size depicted in Figure of description etc., only to coordinate the content disclosed in specification, with
Understand and read for those skilled in the art, be not limited to the enforceable qualifications of the utility model, therefore do not have skill
Essential meaning in art, the modification of any structure, the change of proportionate relationship or the adjustment of size are not affecting the utility model institute
Under the effect that can be produced and the purpose to be reached, all should still fall what is covered in the technology contents disclosed in the utility model
In the range of.Meanwhile, in this specification it is cited such as " on ", D score, "front", "rear", " centre " term, be merely convenient to chat
That what is stated understands, and be not used to limit the enforceable scope of the utility model, and its relativeness is altered or modified, without substantive change
Under more technology contents, when being also considered as the enforceable category of the utility model.
As shown in figure 1, a kind of copper bush of fuel injector extractor, including screw tap 2, fairlead 3 and drawing portion 4.The one of screw tap 2
End is provided with rubber tapered plug 1, and for small end down, drawing portion 4 is arranged on the other end of screw tap 2 to rubber stopper, and screw tap 2 is located in fairlead
In 3 axle center hole.The drawing portion 4 includes guide rod and operation dish, one end connection screw tap 2 of guide rod, the other end end of guide rod
Annular protrusion is provided with, the operation dish is sleeved on guide rod with the movable connection method that can be moved axially along guide rod.By upwards
Rapid lifting operation dish makes it clash into guide rod acting inertial, and screw tap 2 and copper sheathing are integrally extracted.
When using, by the axle center hole of the incoming fairlead 3 of screw tap 2, in lower end insertion copper sheathing, now the end of screw tap 2 is arranged
Rubber tapered plug 1 can seal up the nozzle opening of fuel injector, to prevent operation process in the chip that produces enter engine, play anti-
Shield is acted on.Then screwing screw tap 2 makes its rotation attack certain depth in copper sheathing, and fairlead 3 forms guiding and prevents screw tap to screw tap 2
2 shift shooting copper sheathing process axis.Finally drawing portion 4 is assembled in the upper end of screw tap 2, drawing portion 4 will be upwards lifted
Operation dish, make operation dish to guide rod formed impact, just screw tap 2 and copper sheathing can together be taken out by impulse inertia.
In sum, when is extracted the copper sheathing in engine fuel injector using technology involved by the utility model, labor is operated
Fatigue resistance is reduced, and maintenance efficiency is significantly improved.So, the utility model effectively overcomes some reality of the prior art
Problem is so as to having very high value and use meaning.
Above-mentioned embodiment only illustrative principle of the present utility model and its effect are new not for this practicality is limited
Type.The utility model also has many aspects to be improved on the premise of without prejudice to overall thought, for being familiar with this technology
Personage all can carry out modifications and changes to above-described embodiment under without prejudice to spirit and the scope of the present utility model.Therefore,
Such as those of ordinary skill in the art is without departing from the spirit disclosed in the utility model and institute under technological thought
All equivalent modifications for completing or change, should be covered by claim of the present utility model.
