Abstract
Disclosed is a coaxiality detecting tool composed of a hexagon flange nut, a measuring column and a detection sleeve. When the coaxiality detecting tool is used, a cone of the measuring column is matched with a cone hole of a detected workpiece, the hexagon flange nut is matched with a threaded column of the measuring column, and the measuring column is fixed on the workpiece; an inner hole of the detection sleeve is matched with a detection column, the conical surface of the detection sleeve is in contact with the orifice of a ΦE hole in the workpiece, whether the whole conical surface is in uniform contact with the orifice of the ΦE hole is observed, and if in uniform contact, the detected coaxiality is qualified, otherwise, the detected coaxiality is unqualified.
