Abstract

The invention relates to main pipe press-fitting equipment for an automobile engine. The main pipe press-fitting equipment for the automobile engine comprises a bottom board, a main pipe positioning device installed in the middle of the bottom board, an inner sleeve positioning device arranged below the main pipe positioning device, upper sleeve positioning block devices, lower sleeve positioning block devices and pushing devices, wherein the upper sleeve positioning block devices, the lower sleeve positioning block devices and the pushing devices are symmetrically arranged on the two sides of the main pipe positioning device. Compared with the prior art, the stability is good, and torsion or generation of gaps between threads of an inner sleeve and an upper sleeve as well as between the threads of the inner sleeve and a lower sleeve is avoided.

Description

technical field [0001] The invention relates to an automobile engine tooling equipment, in particular to a main pipe press-fitting equipment for an automobile engine. Background technique [0002] At present, in the EA888Gen3 (automobile engine) high-pressure fuel pipe, the upper, inner, and lower sleeves of the main tube are press-fitted. After pressing, there is an uneven fit between the main tube and the upper and lower sleeves, resulting in an increase in the leakage rate of the product after brazing. In addition Also have the problem of loading difficulty to cause production efficiency to be low. [0003] The Chinese patent application number 03134653.7 discloses the fuel rail, the main pipe for the fuel rail and its manufacturing method, which can prevent cracks at the connecting part of the main pipe and the branch pipe in the fuel rail (common rail), and can be applied to the fuel rail from low pressure to high pressure. Wider range of pressures, not only for gasoli...
