Embodiment Construction
[0039] Such as image 3 As shown, the manufacturing method of the glued fuel tank of the present invention includes the following steps:
[0040] Material preparation step 21
[0041] Such as Figure 4 As shown, in the material preparation step 21, materials are selected, such as SPCEN steel plates, to form upper and lower box units 31, 32 and connecting pipes 33.
[0042] The upper case unit 31 has an upper case 311, an oil inlet 312 formed on the upper case 311, an outer flange 313 protruding from the upper case 311 around the periphery of the oil inlet 312, and a hollow annular oil pump fixing seat 314 .
[0043] Such as Figure 4 , Figure 6 As shown, the upper box body 311 includes a stepped mounting surface 315, an upright portion 310 and a flat portion 310' forming an outer periphery.
[0044] The stepped mounting surface 315 defines a mounting opening 317 that gradually widens outward.
[0045] The upright portion 310 and the plane portion 310' are connected to each other ...
