The invention provides a curved shell plate middle assemblage positioning method, which comprises the following steps of: firstly, providing a sectional jig frame, and determining a shell plate datum line half-width value and a deck datum line half-width value according to a sectional lower opening theoretical half-width value of the sectional jig frame, the width of a lower opening T row and a lower opening reverse deformation amount; then, a deck datum line is surveyed in the deck assembly, and a deck half-width position line perpendicular to the rib position line is surveyed on each gear of rib position line; then, an outer plate datum line correspondingly consistent with the deck datum line is surveyed on an assembly in the outer plate, and the half-width position of the outer plate is surveyed on the rib plate; next, the deck middle assemblage is adjusted to be horizontal to the assembling position. And then the outer plate datum line and the deck datum line are adjusted to be aligned at the end points in the same direction. And finally, the outer plate is adjusted until the marked half-width position of the outer plate is located on the normal line of the assembly in the deck, and the normal line passes through the intersection point of the half-width position line of the deck and the rib position line. The assembling and positioning method in the curved outer plate can be automatically completed at a time, and time, manpower and material resources are saved.

    本发明提供一种曲型外板中组立定位方法,首先提供分段胎架,根据分段胎架的分段下口理论半宽值、下口T排的宽度及下口反变形量,确定外板基准线半宽值及甲板基准线半宽值。然后在甲板中组立上勘划甲板基准线并在每档肋位线上勘划垂直于肋位线的甲板半宽位置线。接下来在外板中组立上勘划与甲板基准线对应一致的外板基准线,并在肋板上勘划外板半宽位置。下一步调整甲板中组立至装配位置水平。然后调整外板基准线与甲板基准线至同一方向的端点对齐。最后调整外板,直至标记的外板半宽位置位于甲板中组立的法向线,法向线经过甲板半宽位置线和肋位线的交点。本发明所述的曲型外板中组立定位方法可以一次性自主完成,节省时间以及人力物力。
