Technical field
The present invention relates to the installing area of cylinder cap fuel injector copper sheathing, more particularly to a kind of cylinder cap fuel injector copper sheathing it is pre-
Auxiliary mould is installed.
Background technology
Existing conventional engines cylinder cap fuel injector copper sheathing assembly method is that direct labor can't see installation annular groove
In the case of, O-ring seal is directly expressed to installation annular groove with feel, copper bush of fuel injector is then taken cylinder from packing case
Above lid mounting hole of oil sprayer, then from raceway mobile cylinder lid to forcing press press mounting copper directly below.Due to sealing ring stress
Inequality, error plus mounting ring groove processing, the O-ring seal installed by hand wave state may occur, can not ensure close
Seal is installed in place.When copper sheathing is manually placed on mounting hole, the pre-determined bit for not carrying out copper sheathing is installed, and press fitting process easily goes out
Existing copper sheathing beat, press damage copper sheathing, or even trimming sealing ring partially.
The characteristics of original engine cylinder cap copper bush of fuel injector installation method is the outer Zhang Gong's dress of no O-ring seal and copper sheathing
Auxiliary positioning, pre-tightening apparatus are pre-installed, copper sheathing sealing leak, gas leakage hidden danger of quality be present, because sealing ring trimming causes cylinder cap
Repair rate is high, and production efficiency is low, and manufacturing cost occupies high.
The information for being disclosed in the background section is merely intended to understanding of the increase to the general background of the present invention, without answering
It has been the prior art well known to persons skilled in the art when being considered as recognizing or implying the information structure in any form.
The content of the invention
It is an object of the invention to provide a kind of pre-installation backman of simple and reasonable cylinder cap fuel injector copper sheathing
Copper sheathing can be pushed into sealed step and carry out pretension positioning by dress, the pre-installation auxiliary mould, so as to reduce or eliminate pressure damage partially
The probability of copper sheathing, manufacturing cost is reduced, exclude hidden danger of quality, improve production efficiency.
To achieve the above object, the invention provides a kind of pre-installation auxiliary mould of cylinder cap fuel injector copper sheathing, including：
Handle, it is laterally set, and middle part offers mounting hole；Connection component, it includes studs and is separately positioned on the double end spiral shell
The locking nut at post both ends, one end of the studs are connected with the mounting hole of the handle, and should by the connection component
The locking nut locking at end；Depth defining flange, it offers screwed hole, for the another of the studs with the connection component
One end connects, and is locked by the locking nut at the connection component end；Mounting hole guide-localization section, limited positioned at the depth
The bottom of position flange, for being adapted to the positioning circumference on cylinder cap mounting hole top；And front end pressure head, led positioned at the mounting hole
To the bottom of positioning section, for directly being contacted with copper sheathing bottom surface, on the inside of the cylindrical importing sealing ring of copper sheathing sealing position.
Preferably, in above-mentioned technical proposal, handle is tubulose.
Preferably, in above-mentioned technical proposal, the diameter of depth defining flange is more than cylinder cap mounting hole.
Preferably, in above-mentioned technical proposal, front end pressure head is multi-diameter shaft
Compared with prior art, the present invention has the advantages that：Copper sheathing can be pushed into by the pre-installation auxiliary mould
Sealed step carries out pretension positioning, so as to reduce or eliminate the probability of pressure damage copper sheathing partially, reduces manufacturing cost, it is hidden to exclude quality
Suffer from, improve production efficiency.

Embodiment
Below in conjunction with the accompanying drawings, the embodiment of the present invention is described in detail, it is to be understood that the guarantor of the present invention
Shield scope is not limited by embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members
Part or other parts.
As shown in Figure 1 to Figure 3, according to the pre-installation backman of the cylinder cap fuel injector copper sheathing of the specific embodiment of the invention
Copper sheathing sealing position is completed before mechanical press mounting copper sheathing and is bumped into sealing ring inner circle, it is specifically included：Handle 1, connection component
2nd, depth defining flange 3, mounting hole guide-localization section 4 and front end pressure head 5.Wherein, handle 1 is limited by connection component 2 and depth
Position flange 3 connect, mounting hole guide-localization section 4 is located at the lower section of depth defining flange 3, for the same spindle guide of cylinder cap mounting hole
To；Front end pressure head 5 directly contacts with copper sheathing bottom surface, and being touched with arm power makes in the cylindrical importing sealing ring of copper sheathing sealing position
Side, acted on so as to play the pre-installation of copper sheathing, then copper sheathing is pressed onto mounting hole bottom by punching machine, complete the close of copper sheathing
Envelope, close-fitting installation, so as to reduce or eliminate the pressure probability of damage copper sheathing and trimming sealing ring partially, manufacturing cost is reduced, excludes matter
Hidden danger is measured, improves production efficiency.
Specifically, handle 1 is tubulose, is laterally set, middle part offers mounting hole, for one end with connection component 2
Connection, for touching by hand on the inside of the cylindrical importing sealing ring for making copper sheathing sealing position, so as to play the effect of the pre-installation of copper sheathing.
