Abstract
The invention discloses a seal type spill-proof plastic oil injection rail of an automobile engine. The seal type spill-proof plastic oil injection rail comprises an oil rail body (1). One end of the oil rail body (1) is an oil inlet end (2), and the opposite end of the oil rail body (1) is a sealing end (3). An installation support (4) is arranged on the side wall of the oil rail body (1). A plurality of oil nozzles (5) are evenly arranged on the oil rail body (1) in the axial direction. The seal type spill-proof plastic oil injection rail is characterized in that the sealing end (3) comprises a welding plug (31), a space bush (32) and a sealing ring (33), the spacer bush (32) is arranged on the inner wall of a pipeline of the oil rail body (1), the sealing ring (33) is arranged between the inner wall of the pipeline of the oil rail body (1) and the spacer bush (32), and the welding plug (31) is fixedly connected with the sealing end (32) of the oil rail body (1) through friction welding. The seal type spill-proof plastic oil injection rail effectively solves the problems that in the production process of an existing oil injection rail, overflowed welding materials are left in an inner cavity of the oil rail and are hard to clean, so that normal working of automobiles is influenced.
Description
Technical field
The present invention relates to technical field of automobile engine, be specifically related to the anti-flash plastics of a kind of motor car engine sealed type oil spout rail.
Background technique
The effect of oil rail is storage fuel oil, suppresses the pressure surge due to high pressure fuel supply pump and oil sprayer oil spout generation simultaneously, guarantees that system pressure is stable.High pressure oil rail is that each cylinder is jointly all, its sign that is common rail system.At present, enterprise is in the rail process that produces oil, the sealed end of oil rail adopts the mode of plug sealing to seal conventionally, because oily rail exists certain pressure in the course of the work, plug should not pass through screw thread, or bonding mode is fixed, conventionally adopt the mode of friction welding that welding plug and the sealing of oily rail are fixed, in friction welding process, in oil rail, in cavity, can enter some fricative weld flash, these weld flash are owing to being high temperature friction generation, falling into interior cavity process is easily bonded together with interior cavity, be difficult to remove, these flashes are in later stage oil spout rail working procedure, can enter motor or other oil ducts, thereby affect the normal operation of automobile.
Summary of the invention
The technical problem to be solved in the present invention is to provide the anti-flash plastics of a kind of motor car engine oil spout rail, the present invention efficiently solves existing oil spout rail in process of production, in oil rail, in cavity, leave over weld flash, weld flash is difficult to cleaning, thereby affects the problem of automobile normal operation.
The present invention is achieved through the following technical solutions:
The anti-flash plastics of a kind of motor car engine sealed type oil spout rail, comprise oily rail body (1), oil rail body (1) one end is oil inlet end (2), opposite end is sealed end (3), on sidewall, be provided with mounting bracket (4), oil rail body (1) is evenly provided with a plurality of oil nozzles (5) vertically, it is characterized in that: described sealed end (3) comprises welding plug (31), spacer (32), seal ring (33), described spacer (32) is arranged at oily rail body (1) inner-walls of duct, between oil rail body (1) inner-walls of duct and spacer (32), be provided with seal ring (33), welding plug (31) is fixedly connected with the sealed end (3) of oily rail body (1) by friction welding.
The further Technological improvement plan of the present invention is:
Described spacer (32) is made for plastic materials, and seal ring (33) is made for rubber material, is that interference fit is connected with oily rail body (1) inner-walls of duct.
The present invention compared with prior art, has obvious advantage,
One, the present invention has increased spacer in the interior cavity of original oily rail body, thereby guarantees that welding plug is in friction welding process, and weld flash can not fall in the interior cavity of oily rail, thereby guarantees the turbidity test in oil duct, guarantees the normal operation of automobile;
Two, between the present invention's oil rail inner-walls of duct and spacer, be provided with seal ring, improved the sealability of oily rail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention includes oily rail body 1, oil rail body 1 one end is oil inlet end 2, opposite end is sealed end 3, on sidewall, be provided with mounting bracket 4, oil rail body 1 is evenly provided with a plurality of oil nozzles 5 vertically, described sealed end 3 comprises welding plug 31, spacer 32, seal ring 33, described spacer 32 is arranged at oily rail body 1 inner-walls of duct, between oil rail body 1 inner-walls of duct and spacer 32, be provided with seal ring 33, welding plug 31 is fixedly connected with the sealed end 3 of oily rail body 1 by friction welding, described spacer 32 is made for plastic materials, seal ring 33 is made for rubber material, be that interference fit is connected with oily rail body 1 inner-walls of duct, in process of production, first spacer 32 is installed on to the sealed end 3 of oily rail body 1, below spacer 32, with the joint of oily rail body 1, seal ring 33 is set simultaneously, then oily rail body 1 is being carried out to friction welding with welding plug 31.
The present invention has reached foregoing invention object in sum.
