The features such as injection pressure height, fast response time, high component technological precision.As in common-rail injector key, core component
High-speed electromagnetic valve is determined because of the features such as its structure size is small, the grade of tolerance and technological parameter requirement are high, dynamic displacement is minimum
Its associated components is one of difficult point and key point of assembly work in common-rail injector assembling, and assembling quality finally influences to produce
The quality and working performance of product.
Utility model content
The purpose of this utility model is to provide a kind of attaching/detaching apparatus for high pressure common rail injector high-speed electromagnetic valve,
It reduces the assembly difficulty of control assembly in high-speed electromagnetic valve by the device, ensure that the assembling quality of associated component is corresponding
Assembly work become efficient and simple.
In order to achieve the above object, the utility model is achieved through the following technical solutions：A kind of attaching/detaching apparatus, for high pressure
The assembling of common-rail injector solenoid valve control component includes cylindrical structural part, and a pair of of short axle is arranged on the cylindrical parts
One end；The cylindrical structural part offers a pair of of auxiliary pin hole, and the opening of the auxiliary pin hole described in a pair is arranged on institute
The same end for a pair of of the short axle stated；The cylindrical structural part, which also extends through, opens up a mesoporous.
The solenoid valve control component includes a locking cap；The locking cap is equipped with the first symmetrical holes and second symmetrically
Hole.
The short axle corresponding inserted is in the first symmetrical holes of locking cap；Second symmetrical holes of the locking cap and institute
The auxiliary pin hole stated is connected.
The auxiliary pin hole and short axle is evenly distributed in an end section of cylindrical parts.
The other end of the cylindrical structural part is polygonized structure.
The utility model has the following advantages compared with prior art：
1st, one end of attaching/detaching apparatus, which is set to polygonized structure, makes spanner be more easy to clamp, make high-speed electromagnetic valve locking cap that can be more easy to
Locking.
2nd, the short axle side Design assistant pin hole of attaching/detaching apparatus uses auxiliary pin in assembling process.On the one hand, auxiliary pin point
The torque that a part of short axle is born is carried on a shoulder pole, and then increases the durability of dismantling device；On the other hand, the position of related features essence of pin hole is aided in
Degree can be lower than short axle and influence using effect, so ensures that using reducing difficulty of processing under conditions of function.
3rd, on the one hand the design of the central hole structure of attaching/detaching apparatus is avoided and may interfered as caused by control bar assembly；It is another
Aspect is convenient for the position relationship between the adjustment ring in observation assembling process, control bar assembly and locking cap.
Description of the drawings
Fig. 1 is a kind of overall structure diagram of attaching/detaching apparatus of the utility model；
Fig. 2 is a kind of attaching/detaching apparatus use state reference chart of this practicality.
Specific embodiment
Below in conjunction with attached drawing, by the way that a preferable specific embodiment is described in detail, the utility model is done and is further explained
It states.
As shown in Figure 1, a kind of attaching/detaching apparatus, cylinder is included for the assembling of high pressure common rail injector solenoid valve control component
Shape structural member, a pair of of short axle 11 are arranged on one end of the cylindrical parts；Cylindrical structural part offers a pair of of auxiliary pin
Hole 12, the opening of the auxiliary pin hole 12 described in a pair are arranged on the same end of a pair of of short axle 11；Cylindrical structural part also extends through out
An if mesoporous 13.As shown in Fig. 2, solenoid valve control component includes a locking cap 2；Locking cap 2 is equipped with the first symmetrical holes and second
Symmetrical holes.11 corresponding inserted of short axle is in the first symmetrical holes of locking cap 2；Second symmetrical holes of locking cap 2 and auxiliary pin hole 12
It is connected.In the present embodiment, auxiliary pin hole 12 is evenly distributed with short axle 11 in an end section of cylindrical parts.It is cylindrical
The other end of structural member is polygonized structure.
It is illustrated in figure 2 a kind of dress of the attaching/detaching apparatus of the utility model for high pressure common rail injector solenoid valve control component
Fit over the principle with high-speed electromagnetic valve installation during actual industrial operation is used：
Control-rod 4 is pressed in positioning sleeve 8 by holding screw 3 in the utility model, composition control bar assembly 6, at a high speed
The moving component of solenoid valve forms connection relation therewith by the screw thread of 8 end of positioning sleeve, when high-speed electromagnetic valve or so opens and closes
During movement, control bar assembly 6 also moves with it, and then realizes fuel-displaced control of the control-rod 4 to fuel injector oil outlet；Locking cap 2
Adjustment ring 7 is pressed in tappet 5.During utility model works, two short axles 11 of attaching/detaching apparatus 1 are inserted into locking cap first
In 2 hole, meanwhile, in one or two pin of two loadings aided in pin holes 12 optionally of attaching/detaching apparatus 1, pulled using torsion
Locking cap 2 by twisting polygon forming head is pressed on by adjusting ring 7 on tappet 5, is so allowed for by setting tightening torque by hand
Locking cap 2 and the gap width of control bar assembly meet the /V requirement of design, but also control bar assembly 6 is with high-speed electromagnetic valve
Its amount of movement is in scope of design during side-to-side movement, so ensure high-speed electromagnetic valve work by design performance, common-rail injector by
Design distributive value and timing working.
The advantages of the utility model is following three points：
1st, the polygonized structure of attaching/detaching apparatus makes spanner be more easy to clamp, high-speed electromagnetic valve locking cap is made reliably to lock.

The torque that a part of short axle is born is carried on a shoulder pole, and then increases the durability of dismantling device；On the other hand, the position of related features essence of pin hole is aided in
Degree can be lower than short axle and influence using effect, so ensures that using reducing difficulty of processing under conditions of function.
3rd, on the one hand the design of attaching/detaching apparatus central hole structure is avoided and may interfered as caused by control bar assembly；The opposing party
Face is convenient for the position relationship in observation assembling process between adjustment ring, control bar assembly, locking cap.
Although the content of the utility model is discussed in detail by above preferred embodiment, but it should be appreciated that on
The description stated is not considered as the limitation to the utility model.After those skilled in the art have read the above, for
A variety of modifications and substitutions of the utility model all will be apparent.Therefore, the scope of protection of the utility model should be by appended
Claim limit.
