The invention relates to a ship shafting integral tail pipe alignment positioning structure and positioning method. An adjusting bracket and adjusting bolts are arranged at each of the front and rear ends of a ship shafting tail pipe; each adjusting bracket is L-shaped, and one end of the adjusting bracket is transversely welded and fixed onto one corresponding fixing base; two pairs of the adjusting bolts are respectively arranged at the front and rear ends, perpendicularly penetrate through two side surfaces of the respective adjusting brackets, and are respectively propped against the ship shafting tail pipe axially and radially, so as to adjust the axial and radial positions of the ship shafting tail pipe; after positioning is finished, an epoxy cushion block is cast between the ship shafting tail pipe and the fixing bases; the adjusting brackets are disassembled, the exposed parts of the adjusting bolts are cut off, and sealing treatment is performed; the fixing base at the front part of the ship shafting tail pipe is a bearing steel casting, and the fixing base at the rear part of the ship shafting tail pipe is a sternpost. Through adoption of the structure and method provided by the invention, alignment positioning is performed on the ship shafting tail pipe in a three-dimensional space, so as to greatly improve the mounting accuracy; the adjusting bolts are not in contact with an epoxy medium, and bubbles and the like are unlikely to generate on the contact surfaces, so that the quality of epoxy casting can be effectively improved.
