Abstract
The utility model discloses a kind of new oil rail, including oil pipe, fuel inlet fitting and copper ring, fuel inlet fitting is equipped with fuel feed hole, fuel feed hole is stepped hole, the first hole section and copper ring cooperation really up to the mark positioned at fuel feed hole one end, and, second hole section adjacent with the first hole section forms axial limiting to copper ring；After soldering, copper ring melts, and R arc is formed at its inner wall.The utility model sets copper ring by interior in fuel feed hole, so that it melts in brazing process and forms arcuation on inner wall, is brazed not full technical problem to solve.
Description
Technical field
The utility model relates to oily rail technical field, in particular to a kind of new oil rail with fuller R arc.
Background technique
Oily rail includes supervisor and fuel inlet fitting, and fuel inlet fitting is equipped with fuel feed hole, and fuel inlet fitting is connected to by its fuel feed hole
The inside of supervisor.In assembling process, the junction of fuel inlet fitting and supervisor can smear copper cream, but copper cream is embedded in state when soldering
Difference, soldering is not full, is unable to satisfy the requirement of R arc 0.3.
Utility model content
The purpose of this utility model is to provide a kind of new oil rails, solve fuel inlet fitting and the junction soldering of supervisor
Not full technical problem afterwards.
To solve the above-mentioned problems, the technical solution of the utility model is:
A kind of new oil rail, including oil pipe and fuel inlet fitting, the fuel inlet fitting are equipped with fuel feed hole, further include copper ring；
The fuel feed hole is stepped hole, is interference fitted positioned at first hole section of fuel feed hole one end and the copper ring, and, with described first
The second adjacent hole section of hole section forms axial limiting to copper ring；After soldering, the copper ring melts, and R arc is formed at its inner wall.
Preferably, after soldering, the maximum inner diameter of the copper ring is equal to the internal diameter of second hole section.
Preferably, the copper ring, the first hole section and the coaxial arrangement of the second hole section.
Compared with the existing technology, the beneficial effects of the utility model are:
A kind of new oil rail of the utility model, has installed copper ring, copper in brazing process additional between the second hole section and oil pipe
Ring melts to a certain extent, and internal ring wall is deformed and forms arcuation, is brazed not full technical problem to solve,
Meet the requirement of R arc 0.3.
Detailed description of the invention
Fig. 1 is a kind of schematic diagram of new oil rail of the utility model.
Wherein, 1, oil pipe, 2, fuel inlet fitting, 201, fuel feed hole, 201-1, the first hole section, 201-2, the second hole section, 3, copper
Ring, 301, R arc, 4, copper cream.
Specific embodiment
It is described in detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, a kind of new oil rail, including oil pipe 1, fuel inlet fitting 2 and copper ring 3, fuel inlet fitting 2 be equipped with into
Oilhole 201, fuel feed hole 201 are stepped hole, the first hole section 201-1 and the cooperation really up to the mark of copper ring 3 positioned at 201 one end of fuel feed hole, and,
The second hole section 201-2 adjacent with the first hole section 201-1 forms axial limiting to copper ring 3；After soldering, copper ring 3 melts, and in it
R arc 301 is formed at wall.
Specifically: several fuel inlet fittings 2 are disposed on oil pipe 1, each fuel inlet fitting 2 passes through its corresponding fuel feed hole
201 are connected to oil pipe 1, and a copper ring 3 is equipped in each fuel feed hole 201.Fuel feed hole 201 is stepped hole, straight according to each section
Diameter is divided into several hole sections, wherein being the first hole section 201-1 near oil pipe 1, adjacent with the first hole section 201-1 is second
Hole section 201-2.Copper ring 3 is compressed the first hole section using press-fit approach when assembly by the first hole section 201-1 and the cooperation really up to the mark of copper ring 3
In 201-1.The internal diameter of second hole section 201-2 is less than the first hole section 201-1, and therefore, the second hole section 201-2 forms one to copper ring 3
Road axial limiting, in brazing process, copper ring 3 melts, and the second hole section 201-2 effectively prevents 3 Deformation Flow of copper ring to the second hole
In section 201-2.In brazing process, copper ring 3 melts to a certain extent, and internal ring wall is deformed and is formed as shown in Figure 1
Arcuation, to meet the requirement that R arc 301 reaches 0.3.
The utility model sets copper ring 3 by interior in fuel feed hole 201, so that it melts in brazing process and on inner wall
Arcuation is formed, is brazed not full technical problem to solve.
In one embodiment, after soldering, the maximum inner diameter of copper ring 3 is equal to the internal diameter of the second hole section 201-2.Come in detail
Say: the second hole section 201-2 of the application is equivalent to the hole section for being connected to oil pipe 1 in the prior art, and the application is in the second segmental arc and oil
Copper ring 3 is installed between pipe 1 additional, it is therefore preferable that the maximum inner diameter of the copper ring 3 is equal to the internal diameter of the second hole section 201-2, to guarantee oil
Best using effect is presented in rail.
In one embodiment, copper ring 3, the first hole section 201-1 and the second hole section 201-2 coaxial arrangement, to guarantee copper
Variation of the ring 3 in soldering and subsequent process has controllability.
Oil rail finished product provided by the utility model is as shown in Figure 1, copper ring 3 is connected with copper cream 4, so that oily rail has very
Good plumpness.
Disclosed above is only some embodiments of the application, and however, this application is not limited to this, any this field
Technical staff can think variation, should all fall in the protection domain of the application.
