Description
Technical Field
The utility model relates to an automobile parts especially relates to a water pipe joint for engine.
Background
At the present stage, water outlet pipes used in an engine are usually single injection molding parts, the parts need to be connected after being divided into an upper shell and a lower shell due to the difficulty in mold stripping of a mold, the pressure of cooling liquid of 3bar inside the parts needs to be met by a water pipe joint, and the common connection mode of the upper shell and the lower shell has high leakage failure rate under a long-time high-pressure working condition and cannot meet the requirement.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the structural shortcoming of prior art, provide an engine water pipe joint, this engine water pipe joint realizes vibration friction welding through special structural design, satisfies the inside 3 bar's of water pipe joint coolant pressure force and does not leak.
In order to achieve the above object, an embodiment of the present invention provides a water pipe joint for engine, which is realized by the following technical scheme:
a water pipe joint for an engine is characterized in that: the water pipe joint is formed by buckling an upper pipe body and a lower pipe body to form a pipe body for liquid to flow; a cooling liquid inlet is formed at one end of the pipe body, a first fixed seat used for connecting an engine body is arranged around the cooling liquid inlet, and a radiator interface is formed at the other end of the pipe body; a second fixed seat is arranged around the radiator interface; the middle part of the lower pipe body is provided with a warm air interface and an engine oil pipeline interface; an engine cooling small circulation interface is arranged on the upper pipe body close to the cooling liquid inlet; the welding end face of the upper pipe body is provided with friction welding ribs along the length direction, the welding end face of the lower pipe body is provided with a flash tank matched with the friction welding ribs along the length direction, and the flash tank is internally provided with fusion welding ribs.
The width of the fusion welding rib does not exceed 1/2 of the width of the friction welding rib.
The width of the fusion welding rib is 1/2 of the width of the friction welding rib.
Compared with the prior art, the beneficial effects of the utility model are that:
vibration friction welding is realized through special structural design, and the requirement that the cooling liquid pressure of 3bar in the water pipe joint is not leaked is met.

Detailed Description
The invention will be described in further detail below with reference to the accompanying drawings so as to facilitate understanding by those skilled in the art:
referring to fig. 1-5, the present invention relates to a water pipe joint for an engine, which is formed by fastening an upper pipe body 1 and a lower pipe body 2 to form a pipe body for flowing liquid. One end of the tube forms a coolant inlet 3. Around the coolant inlet 3, the end of the tube is also provided with a first fixed seat 4 for connection to the engine block. The other end of the tube opposite the coolant inlet 3 forms a radiator connection 5. And surrounds the radiator port 5, and the end of the pipe body is provided with a second fixed seat 6 which can be used for connecting with a radiator. Screw holes are formed in the second fixing seat 6 and the first fixing seat 4.
The middle part of the lower pipe body 2 is provided with a warm air interface 21 and an engine oil pipeline interface 22. An engine cooling small circulation interface 11 is arranged on the upper pipe body 1 close to the cooling liquid inlet 3.
In addition, a friction welding rib 12 is arranged along the welding end face of the upper pipe body 1 along the length direction thereof, a flash groove 23 matched with the friction welding rib 12 is arranged along the length direction of the welding end face of the lower pipe body 2, and a fusion welding rib 24 is arranged in the flash groove 23. The width of the fusion-welded rib 24 does not exceed 1/2 of the width of the friction-welded rib 12. Thereby realizing the sealing connection of the two by means of vibration friction welding. Preferably, the width of the fusion-welded rib 24 is 1/2 the width of the friction-welded rib 12.
The advantages are that: vibration friction welding is realized through special structural design, and the requirement that the cooling liquid pressure of 3bar in the water pipe joint is not leaked is met.
The above embodiments are intended to illustrate the present invention and the embodiments in detail, but it can be understood by those skilled in the art that the above embodiments of the present invention are only one of the preferred embodiments of the present invention, and for space limitation, all embodiments can not be listed here one by one, and any implementation that can embody the technical solution of the present invention is within the protection scope of the present invention.
