Frock is filled, which makes its even circumferential be close to mounting groove, so as to reduce or eliminate pressure damage copper sheathing partially
With the probability of trimming sealing ring, manufacture cost is reduced, excludes hidden danger of quality, improves production efficiency.
To achieve the above object, the utility model provides a kind of mounting tool of cylinder cap fuel injector copper sheathing sealing ring,
Including：Handle, it is laterally set, and middle part offers mounting hole；Connection component, it includes studs and is separately positioned on this pair
The locking nut at header stud both ends, one end of the studs are connected with the mounting hole of the handle, and pass through the connection group
The locking nut locking at the part end；Depth defining flange, it offers threaded hole, for the studs with the connection component
Other end connection, and locked by the locking nut at the connection component end；Mounting hole guide-localization section, positioned at the depth
The lower part of defining flange is spent, for being adapted to the positioning circumference on cylinder cap mounting hole top；And a circle section outside sealing ring, positioned at institute
The lower part of mounting hole guide-localization section is stated, is uniformly pressed into it in mounting groove for being set with O-ring seal.
Preferably, in above-mentioned technical proposal, the lower part of a circle section is additionally provided with guiding cone outside sealing ring.
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, a circle section and handle are made using nylon outside guiding cone, sealing ring.
Compared with prior art, the utility model has the advantages that：The mounting tool crush seal circle makes its circle
Week is uniformly close to mounting groove, so as to reduce or eliminate the pressure probability of damage copper sheathing and trimming sealing ring partially, reduces manufacture cost, row
Except hidden danger of quality, production efficiency is improved.

Embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality
New protection domain and from the limitation of 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 peace of the cylinder cap fuel injector copper sheathing sealing ring of the utility model embodiment
Dress frock specifically includes：Circle section 3, guiding cone 4, connection component 5 and installation outside handle 1, depth defining flange 2, sealing ring
Hole guide-localization section 6.Wherein, a circle section 3 is used to be set with O-ring seal 7 outside sealing ring, and O-ring seal 7 passes through guiding cone 4
A circle section 3 is inserted in outside sealing ring, mounting hole guide-localization section 6 is driven on cylinder cap mounting hole top by handmade rotary handle 1
Circle rotation is positioned, O-ring seal 7 can be uniformly pressed into mounting groove, so as to reduce or eliminate pressure damage copper sheathing partially and cut
The probability of side sealing ring, reduces manufacture cost, excludes hidden danger of quality, improve production efficiency.
Specifically, handle 1 is laterally set, and middle part offers mounting hole, for being connected with one end of connection component 5, is used
Mounting hole guide-localization section 6 is driven in the positioning circle rotation on cylinder cap mounting hole top in handmade rotary.
