Embodiment
During carrying out the press fitting of cylinder body oil injection nozzle on assembly line, since certain factors cause oil injection nozzle press fitting not conform to
Lattice.When needing to take out oil injection nozzle from cylinder body, because not having specific purpose tool, Workers only use locking pliers toward out
It pulls out.
In addition, in Automobile Service work, it is often necessary to remove the atomizer of engine, but existing atomizer removing method
It is by force to be pulled out atomizer with crowbar, not only inconvenient, low efficiency, but also engine is easily damaged in operation
Other positions.
Because space is narrow, locking pliers is big, and bad when firmly extracting upwards firmly conventional method is relatively difficult, consumption
When effort.Sometimes firmly uneven because rolling in withdrawal process, causing oil injection nozzle to fracture in cylinder body can not take out, most
Rear-bank rotor housing can only scrap processing.
For these reasons, the utility model provides a kind of atomizer extractor 200.
Referring to FIG. 1, Fig. 1 shows the specific structure of the atomizer extractor 200 provided in embodiment.The atomizer takes
Device 200 includes ontology 210, collet 220, movable mandril 230 and rotation mandril 240 out.
Wherein, referring to figure 2., ontology 210 is the hollow type structure extended along preset direction, and has opposite first end
211 and second end 212.
Referring to figure 3. and Fig. 4, collet 220 are arranged in first end 211, and collet 220 includes the inner space with ontology 210
The opening 221 of connection, is provided with the movable jaw 222 being slidably matched with opening 221 at opening 221, and movable jaw 222 is used for
Clamp atomizer.
Movable mandril 230 is protruded into ontology 210 by second end 212, and movable mandril 230 is used for living with the inner wall of ontology 210
Dynamic cooperation, and movable jaw 222 is pushed to slide relative to opening 221 to clamp atomizer.
Rotation mandril 240 is connect with the inner thread of second end 212, and rotation mandril 240 protrudes into ontology 210 and movable top
Bar 230 against.
The atomizer extractor 200 includes ontology 210, collet 220, movable mandril 230 and rotation mandril 240.Wherein, originally
Body 210 has opposite first end 211 and second end 212, and first end 211 is provided with movable jaw 222, in second end
212 are provided with rotation mandril 240.In addition, ontology 210 is the hollow type structure extended along preset direction, in the inside of ontology 210
Be additionally provided with movable mandril 230 in space, the both ends of movable mandril 230 respectively with movable jaw 222 and rotation 240 phase of mandril
Against.Since rotation mandril 240 is connect with the inner thread of ontology 210, therefore low bar is rotated by rotation, rotation is enabled to push up
Bar 240 is mobile in the inner space of ontology 210, and protrudes into or stretch out relatively ontology 210.It is protruded into when rotation mandril 240 is opposite
When ontology 210, it will drive movable mandril 230 and moved in ontology 210, and push movable jaw 222 sliding relative to opening 221
Dynamic, when movable jaw 222 is slided relative to opening 221, movable jaw 222 can clamp atomizer.
Further, in the present embodiment, it is located at one end outside ontology 210 equipped with snap ring 241, card in rotation mandril 240
Ring 241 is used to cooperate with drawbench.It is easy for cooperating with drawbench by 241 mother of the snap ring, raising takes by drawbench
Stability during atomizer out.
In addition, in moving process of the rotation mandril 240 relative to the inner space of ontology 210, to make movable mandril
230 with rotation 240 abutment end of mandril to neutrality, enable the contact direction of movable mandril 230 and rotation mandril 240
It is parallel with the axis of ontology 210, thus rotation mandril 240 and movable mandril 230 against one end setting tapered portion 242,
Movable mandril 230 is equipped with the cone tank for cooperating with tapered portion 242 close to one end of rotation mandril 240.
For the ease of clamping atomizer, while the stability of clamping is improved, therefore movable jaw 222 includes the first clamping jaw and the
Two clamping jaws, and in order to enable in clamping process atomizer uniform force, therefore the first clamping jaw and the second clamping jaw are relative to opening
The axisymmetrical setting of mouth 221.
Outside it, after the clamping of movable jaw 222 is completed in order to prevent, when taking out fuel injector by drawbench, in the first folder
Pawl and the second clamping jaw are slided on the contact surface of atomizer, therefore are respectively provided on the inner peripheral surface of the first clamping jaw and the second clamping jaw
There is latch, the frictional force between the first clamping jaw and the second clamping jaw and the contact surface of atomizer can be increased by latch, increase makes
Stability.
Further time, it should be noted that be so that movable jaw 222 is during mobile relative to opening 221 the
Interval between one clamping jaw and the second clamping jaw can change, so that movable jaw 222 can be completed to clamp and loosen
State is provided with the tapered surface for cooperating with movable jaw 222 at opening 221, passes through movable jaw 222 and opening 221
The tapered surface at place matches, and can be moved by movable jaw 222 relative to opening 221, to the first clamping jaw and the second clamping jaw
Between interval be adjusted.
In addition, for the installation convenient for collet 220 and movable jaw 222, collet 220 is threadedly coupled with ontology 210.
Further, in the present embodiment, rotation mandril 240 includes stud and the nut being threadedly engaged with stud, spiral shell
One end of column is connect with the inner thread of ontology 210, and nut is located at the other end of stud.
Outside it, in the other embodiments of the utility model, for this can also to be arranged in drawbench cooperation snap ring 241
The outer peripheral surface of body 210.
Based on above-mentioned atomizer extractor 200, the invention also discloses a kind of atomizer withdrawing device, including it is upper
The atomizer extractor 200 stated, and for driving clamping to have the atomizer extractor 200 of atomizer mobile relative to engine
Drawbench.
The working principle of the atomizer extractor 200 is：
The atomizer extractor 200 includes ontology 210, collet 220, movable mandril 230 and rotation mandril 240.Wherein, originally
Body 210 has opposite first end 211 and second end 212, and first end 211 is provided with movable jaw 222, in second end
212 are provided with rotation mandril 240.In addition, ontology 210 is the hollow type structure extended along preset direction, in the inside of ontology 210
Be additionally provided with movable mandril 230 in space, the both ends of movable mandril 230 respectively with movable jaw 222 and rotation 240 phase of mandril
Against.
Since rotation mandril 240 is connect with the inner thread of ontology 210, therefore low bar is rotated by rotation and enables to rotate
Mandril 240 is mobile in the inner space of ontology 210, and protrudes into or stretch out relatively ontology 210.
When rotation mandril 240 is opposite protrudes into ontology 210, it will drive movable mandril 230 and moved in ontology 210, and push away
Dynamic movable jaw 222 is slided relative to opening 221, when movable jaw 222 is slided relative to opening 221,222 energy of movable jaw
Enough clamp atomizer.
When movable jaw 222 is clamped in outside atomizer, by the cooperation of drawbench and snap ring 241, machine oil can be sprayed
Mouth is extracted out of cylinder body.
The atomizer extractor 200 is easy to use, easy to operate and can cooperate with drawbench as a result, easily will
Oil injection nozzle is extracted out of cylinder body, reduces labor intensity of workers.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
