The invention vertical application number 202111567246.3 provides an integral type assembly positioning tool which has the advantages that the assembly positioning of all external parts on a cylinder can be completed at one time, but the tool is only suitable for being used on a small-diameter shell, and the problem of inconvenient disassembly can occur after the tool is used for a large-diameter shell.
