Description
Technical field
The utility model is related to engine component field, more specifically, it relates to a kind of engine water outlet lid bend pipe
Assembly.
Background technology
Outflow cover for water and bend pipe are all to start always component part, in order to improve the leakproofness of the assembling of bend pipe and outflow cover for water,
Bend pipe and outflow cover for water are integrally castings, and wherein sebific duct, which is inserted in bend pipe, realizes draining, but the bend pipe surface that die casting comes out is more thick
Rough, sebific duct is inserted in rear easy leak, and engine performance is caused to decline, while bend pipe has bending structure and tube wall is relatively thin, pressure
Casting process is difficult to demould, and improves manufacture difficulty.
Utility model content
To go out in view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of engines convenient for manufacture
Water cover bend pipe assembly reduces manufacture cost, while also avoids the problem that leak.
To achieve the above object, the utility model provides following technical solution：
A kind of engine water outlet lid bend pipe assembly, including outflow cover for water and several bend pipes, the outflow cover for water is used and is cast into
Type, the outflow cover for water is equipped with to be included and the matched press-in of mounting hole with the corresponding mounting hole of several bend pipes, the bend pipe
End and with gum cover is matched is inserted in end；The outer diameter tolerance at the press-in end is+0~0.02mm, and the press-in end circularity is
0.01mm；The hole tolerance of the mounting hole is -0.01~0.02mm；The press-in end coats fluid sealant and forms sealant, and
And in press-in mounting hole.
The utility model is further set：Lateral wall at press-in end is equipped with the spacing ring of radial protrusion, when bend pipe is pressed into
After mounting hole, the end face of the spacing ring and mounting hole is inconsistent.
The utility model is further set：The sealing ring for also being provided with radial protrusion is held being inserted in, described be inserted in is held by close
Seal ring is matched with gum cover.
The utility model advantageous effect：Wherein outflow cover for water and bend pipe separate independent manufacture, effectively simplify outflow cover for water structure, just
In water outlet die cast, while bend pipe may be used machining, convenient for manufacture, while also improve the precision on bend pipe surface,
So that the problem of after being inserted in leak will not occur for sebific duct, while the outer diameter tolerance for being pressed into end is allowed to be+0~0.02mm, it is described
Press-in end circularity is 0.01mm；The hole tolerance of the mounting hole is -0.01~0.02mm, then coats fluid sealant at press-in end
Form sealant, and be pressed into mounting hole, the sealed connection of bend pipe and outflow cover for water can be effectively ensured, overcome traditional bend pipe and
The integrally manufactured technology prejudice of outflow cover for water reduces manufacture difficulty, while also avoids the problem that bend pipe coordinates easy leak with gum cover.

Specific embodiment
With reference to attached drawing 1 to Fig. 3, to the utility model, a kind of engine water outlet lid bend pipe assembly embodiment is done further in detail
Explanation.
A kind of engine water outlet lid bend pipe assembly, including outflow cover for water 1 and several bend pipes 2, the outflow cover for water 1 uses die casting
Molding, the outflow cover for water 1 is equipped with to be included matching with mounting hole 11 with several 2 corresponding mounting holes 11 of bend pipe, the bend pipe 2
The press-in end 21 of conjunction and with gum cover is matched is inserted in end 22；The outer diameter tolerance at the press-in end 21 is+0~0.02mm, institute
It is 0.01mm to state press-in 21 circularity of end, and the hole tolerance of the mounting hole 11 is -0.01~0.02mm, can ensure to be pressed into this way
End 21 is interference fit with mounting hole 11；The press-in end 21 coats fluid sealant and forms sealant, and be pressed into mounting hole 11,
So that press-in end 21 securely rests within mounting hole 11, while also function to sealing function.
Wherein outflow cover for water 1 and bend pipe 2 separate independent manufacture, effectively simplify 1 structure of outflow cover for water, convenient for being discharged die cast,
Bend pipe 2 may be used machining simultaneously, convenient for manufacture, while also improve the precision on 2 surface of bend pipe so that after sebific duct is inserted in
The problem of leak will not occur, while the outer diameter tolerance for being pressed into end 21 is allowed to be+0~0.02mm, press-in 21 circularity of end
For 0.01mm；The hole tolerance of the mounting hole 11 be -0.01~0.02mm, then press-in end 21 coat fluid sealant formed it is close
Sealing, and be pressed into mounting hole 11, the sealed connection of bend pipe 2 and outflow cover for water 1 can be effectively ensured, to replace traditional bend pipe 2
The integrally manufactured technical solution with outflow cover for water 1, simple manufacture difficulty, while bend pipe 2 is also avoided to coordinate easy leak with gum cover
Problem.
Lateral wall at press-in end 21 is equipped with the spacing ring 211 of radial protrusion, described after bend pipe 2 is pressed into mounting hole 11
Spacing ring 211 and the end face of mounting hole 11 are inconsistent, it is possible to prevente effectively from the excessively press-in mounting hole 11 of press-in end 21, convenient for peace
Dress, while 22 sealing rings for also being provided with radial protrusion are held being inserted in, the end 22 of being inserted in is matched by sealing ring with gum cover, is made
It obtains gum cover and flexible deformation occurs, it is made to be pressed on always and is inserted in end 22, improves the leakproofness of bend pipe 2 and gum cover.
The above is only the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, all technical solutions belonged under the utility model thinking belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, several improvement under the premise of the utility model principle is not departed from and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
