The invention provides a liquid rocket storage tank thin-wall end socket cold machining trepanning tool and method.The liquid rocket storage tank thin-wall end socket cold machining trepanning tool comprises an annular plate, arc-shaped supporting rib plates which are evenly arranged in the circumferential direction are fixed to the top end of the annular plate, and the outer edge contours of the arc-shaped supporting rib plates are attached to the inner wall of a storage tank thin-wall end socket to be clamped; the top center parts of the arc-shaped supporting rib plates are fixedly connected through a top plate. The tool can be used for effectively positioning and supporting the thin-wall end socket of the liquid rocket storage tank, so that the accuracy of the hole opening position of the end socket of the rocket storage tank and the precision requirement of the hole are ensured, the mounting position of each connecting pipe is controlled within the tolerance range, various static, dynamic and thermal load
