Detailed Description

Referring to fig. 1 to 2, the present invention discloses a main pipe 100 for an oil rail, which includes a first module 13, a second module 23 assembled to the first module 13, a third module 33 assembled to the second module 23, and a fourth module 43 assembled to the third module 33. An oil inlet 5 is fixed at the end of the outer side of the first module 13, and a sensor interface 6 is fixed at the end of the outer side of the fourth module 43. The sensor interface 6 is used to connect a pressure sensor (not shown) to detect the fuel pressure in the main pipe 100 for the fuel rail. A first oil cup 11 used for connecting an oil injector is fixed on the first module 13, a second oil cup 21 used for connecting the oil injector is fixed on the second module 23, a third oil cup 31 used for connecting the oil injector is fixed on the third module 33, and a fourth oil cup 41 used for connecting the oil injector is fixed on the fourth module 41. The use of the modularized main pipe member for the oil rail instead of the conventional integrated main pipe member for the oil rail can achieve cost reduction and simplification of the process flow. Meanwhile, the length of the main pipe 100 for the oil rail may also be changed as needed. Replacement may also be performed when a certain module of the main pipe 100 for the oil rail is damaged. The module of the main pipe 100 for the oil rail is designed in a shape, so that the manufacturing cost can be reduced and the assembly complexity can be reduced. It is also possible to design the modules of the main pipe 100 for the oil rail in two shapes, for example, the first module 13 and the third module 33 are the same in shape, and the second module 23 and the fourth module 43 are the same in shape. The module of the main pipe 100 for the oil rail can be designed into more shapes according to actual requirements so as to be assembled into main pipes for oil rails with different lengths.

The first block 13, the second block 23, the third block 33 and the fourth block 43 may be forged to increase the pressure resistance of the main tubular for the oil rail. Each module is formed by forging followed by machining.

Referring to fig. 3 to 5, in the assembly, the first welding material 12 is assembled between the first module 13 and the second module 23, the second welding material 22 is assembled between the second module 23 and the third module 33, and the third welding material 32 is assembled between the third module 33 and the fourth module 43. Since the connection relationship between the first module 13, the second module 23, the third module 33, and the fourth module 43 and the shape of each module are the same, only the connection relationship between the first module 13 and the second module 23 and the shape of the second module 23 will be described later for the sake of simplicity.

The first module 13 is provided with a first mounting hole 132, the second module 23 is provided with a first mounting portion 232 extending into the first mounting hole 132, and the first mounting portion 232 is fixed to the first module 13 by welding. The first mounting hole 132 is in clearance fit with the first mounting portion 232, and the first welding material 12 is melted and filled into the clearance between the first mounting hole 132 and the first mounting portion 232 by capillary action to achieve welding fixation. The gap between the first mounting hole 132 and the first mounting portion 232 is the gap between the side surface 133 of the first mounting hole 132 and the side surface 2321 of the first mounting portion 232.

The first welding material 12 is located between the front end surface of the first mounting portion 232 and the bottom surface of the first mounting hole 132, and the first welding material 12 is attached to the side surface of the first mounting hole 132. The assembled main pipe for the oil rail is put into a brazing furnace, the first welding material 12 is melted at a high temperature, and the melted first welding material 12 flows into the gap between the first mounting portion 232 and the first mounting hole 132 by capillary action, thereby fixing the first module 13 and the second module 23 together. The welding material flowing between the first mounting portion 232 and the first mounting hole 132 forms the welding layer 14. The second module 23 is provided with a through hole 233 through which fuel flows, a main body 231, and a mounting hole 234. For convenience of assembly, the first mounting portion 232 and the first mounting hole 132 are both cylindrical.

In order to preposition the first module 13 and the second module 23, a fixing portion 15 is provided outside a joint of the first module 13 and the second module 23. The fixing portion 15 may be formed by welding.

As further shown in fig. 6, the outer surface of the first mounting portion 232 is provided with a first recess 235, and the first mounting hole 132 is provided with a second recess 134 that mates with the first recess 235. The first solder material 12 is disposed within the aperture formed by the first recess 235 and the second recess 134. This arrangement allows the first module 13 and the second module 23 to be pre-positioned, and also allows the melted welding material to remain between the first mounting portion 232 and the first mounting hole 132 as much as possible.

It will be apparent to those skilled in the art that various modifications and variations can be made to the above-described exemplary embodiments of the present invention without departing from the spirit and scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
