The invention relates to the technical field of measuring tools and particularly relates to an inner conical surface measuring device. The inner conical surface measuring device comprises a main body,a first reference ruler and a second reference ruler. The first reference ruler and the second reference ruler are connected with two ends of the main body, and a distance between the first referenceruler and the second reference ruler can be changed. The first reference ruler and the second reference ruler can extend into an inner cavity of a floating seal seat from a large-diameter end of thefloating seal seat at the same time, the extending distances of the first reference ruler and the second reference ruler extending into the floating seal seat are the same, and a connecting line between an abutting point of the first reference ruler and an abutting point of the second reference ruler penetrates through a circle center of a section circle. The first reference ruler and the second reference ruler change the s
