Difference in height with the second buckle is 2.5mm.
As an improvement of the present invention, the assembling assembly further includes elastic slice, and the elastic slice is from the card on built-in part
Buckle structure is inserted in.
As an improvement of the present invention, the assembling assembly further includes multilayer cover, and the multilayer cover is welded on fuel tank
Outside.
As an improvement of the present invention, the groove structure of 2.5mm is provided on the fuel tank.
As an improvement of the present invention, wing structure, the setting of the wing symmetrical configuration are provided on the elastic slice
In the two sides of elastic slice.
A kind of assembly method applied to the built-in part assembling assembly on fuel tank, the described method comprises the following steps: 1) bullet
Piece is inserted in from the buckle structure on built-in part；Elastic slice and inner wall of oil tank have the amount of interference of 3.2mm, in stress after assembling
State prevents built-in part Z-direction play；
2) built-in part and elastic slice are protruded into fuel tank internal from oil pump mouth together by worker, and fuel tank is assembled to from open-celled structure
On；
3) positioning pin is placed in the buckle structure of built-in part upper end, is interference fitted with buckle structure, prevents from buckling
Standard is to fuel tank after-contraction；
4) outside weldings multilayer end cap 1；
5) on fuel tank design 2.5mm groove structure, on built-in part buckle structure first buckle and second buckle
Difference in height e is corresponding；Assemble mistake proofing；
6) there is the label on arrow mark and oil tank body corresponding on built-in part, assemble mistake proofing.
Compared with the existing technology, advantages of the present invention is as follows: 1) the technical solution overall construction design is compact, ingenious, should
Fuel tank built-in part is mounted on fuel tank by scheme by the way of being mounted directly, and is solved due to the bad bring welding of welding procedure
Poor quality, and welding mounting means installation quality it is not high the problems such as, which avoids fuel-steam and passes through weldering
The problem of place of connecing is leaked, 2) program is without using expensive tooling devices such as bonding machines, and the assembly parts structure
Simply, design cost is greatly reduced, the problem of built-in part is moved up and down and fallen off is avoided after assembly；3) program fuel tank sheet
The shaping speed of body is also accelerated, and the time for installing fuel tank built-in part is short, conveniently, and fuel tank shortens on the entire production time, mentions
High production efficiency；4) cost is relatively low for entire technical solution, promotes and applies convenient for further.
