Description
Technical field
The invention belongs to mechanical maintenance tool in use, relates generally to the special electric-controlled fuel injector tight cap of oil nozzle Special ejector of card.
Background technology
As the upgrading of China's diesel engine emissions regulations is perfect, domestic diesel engine uses electronic control injection technology to meet one after another
It is required that the HEUI Medium pressure common rail systems of wherein Ka Te companies are exactly a kind of important technology path.At present, it is domestic there is no producer also
Press common-rail injector in production HEUI, country's maintenance is all import diesel engine, installation be all import card spy HEUI
System, wherein the special fixture of needs is decomposed in the dismounting for blocking special electric-controlled fuel injector, complicated, manufacturing cost is high.Block special oil spout
The difficult point of device dismounting is its tight cap of oil nozzle.Due to being cylinder, therefore can not be dismantled using ordinary casing.Currently, domestic dimension
Repair market and clamped using simple board-like clamping tool or pipe wrench and block special atomizer, its axial direction, radial positioning are unreliable, such
Instrument easily causes the deformation of tight cap of oil nozzle, or even damage.
The content of the invention
The purpose of the invention is aiming at the above-mentioned problems of the prior art, with reference to the reality of China's market in repair service
Demand, R ＆ D design is a kind of to block special electric-controlled fuel injector tight cap of oil nozzle Special ejector, reaches simple in construction, cheap, uses
Simple and convenient, the purpose for avoiding causing tight cap of oil nozzle damage.
What the purpose of the invention was realized in：In telescopic positioning with being coordinated on dismounting body exterior by screw thread
The installation and adjustment set being axially movable, outside the adjusting set on negative camber shape round buss is fixedly mounted with by trip bolt, in institute
State telescopic positioning and four locking pins are installed with inserting radially movable in dismounting main body, four lockings pin is located at
In curved round buss barrel chamber, suit compression spring is nailed in the stop pin, one end of the compression spring with it is telescopic fixed
Position coordinates with dismounting body contact, and the other end of compression spring nails on axially position, the outer end of the locking pin in stop pin
The negative camber of face and negative camber shape round buss is in be engaged, and so far forms and blocks special electric-controlled fuel injector tight cap of oil nozzle special dismounting
Device.
The specific purpose tool that the invention is a kind of special electric-controlled fuel injector tight cap of oil nozzle dismounting of card or installation exercise uses, tool
Have simple in construction, manufacturing cost is cheap, using operation simple and convenient, dismounting is reliable, efficiency high, to tight cap of oil nozzle not damaged, suitable
With scope it is wide the characteristics of, the tight cap of oil nozzle of the special electric-controlled fuel injector of card of various models can be dismounted.
Brief description of the drawings
Fig. 1 is the special electric-controlled fuel injector tight cap of oil nozzle Special ejector general structure schematic diagram of card；
Fig. 2 is Fig. 1 top view；
Fig. 3 is A-A profiles in Fig. 1.
Piece number explanation in figure：
1st, it is telescopic positioning with dismounting main body, 2, adjusting set, 3, trip bolt, 4, lock pin, 5, compression spring, 6, it is interior
Curved round buss, 7, the special fuel injector tight cap of oil nozzle of card.
Embodiment
The invention embodiment is described in detail below in conjunction with the accompanying drawings.It is tight that one kind blocks special electric-controlled fuel injector oil nozzle
Cap Special ejector, the installation and adjustment set being axially movable is coordinated by screw thread on outside main body 1 with dismantling in telescopic positioning
2, outside the adjusting set 2 on negative camber shape round buss 6 is fixedly mounted with by trip bolt 3, in the telescopic positioning and dismounting
Four locking pins 4 are installed in radially movable inserting in main body 1, and four lockings pin 4 is located at curved round buss 6
Intracavitary, compression spring 5, one end of the compression spring 5 and telescopic positioning and dismounting main body are set with the locking pin 4
1 is engaged, the other end of compression spring 5 axially position on locking pin 4, the outer face of the locking pin 4 and introversion
The negative camber of face shape round buss 6 is in be engaged.
When being dismantled to the special electric-controlled fuel injector tight cap of oil nozzle of card, block special one end of fuel injector tight cap of oil nozzle 7 and configure upward, will
It is overall reliable fixed to block special fuel injector, in telescopic positioning with rotating adjusting set 2 in dismounting main body 1, and drives negative camber shape to justify
Sleeve 6 moves downwards relative to telescopic positioning with dismantling main body 1, under the thrust of compression spring 5, when locking in pin 4
After end part is retracted to telescopic positioning and dismantled in the jack of main body 1, this Special ejector is integrally covered and fits over the special fuel injector of card
The outside of tight cap of oil nozzle 7 is upper axially, radial positioning, then in telescopic positioning with rotating adjusting set 2 in dismounting main body 1, and drives
The relative sleeve formula of negative camber shape round buss 6 positions to be moved upward with dismounting main body 1, in the negative camber of interior curved round buss 6
Under thrust, locking pin 4 is moved radially, and its inner end part is stretched out from telescopic positioning with dismantling in the jack of main body 1, with this
Synchronous, both circumferentially the positioning of rotary regulating sleeve cartridge type is with dismantling main body 1, until locking pin 4 is inserted in the special fuel injector oil nozzle of card
After in the corresponding aperture of tight cap 7, adjusting set 2 is screwed, rotates this Special ejector with spanner class instrument, in the case where locking pin 4 acts on,
The special fuel injector tight cap of oil nozzle 7 of card is unscrewed from the special fuel injector of card and pulled down, is fulfiled assignment.It is identical with demounting procedure during assembling, only
Rotation direction is opposite when can screw card special fuel injector tight cap of oil nozzle 7.
