ABSTRACT:
An apparatus for measuring taper on mechanical workpieces having a tapered surface, including first and second reference bodies for cooperating with the tapered surface along relevant circumferences of different diameters, a measuring transducer for providing indications responsive to the position of the first and second reference bodies, a support for the first and second reference bodies and first and second connectors connecting the first and second reference bodies, respectively, to the support. The first and second reference bodies define a first revolutionary surface and a second revolutionary surface, the revolutionary surfaces being coaxial between each other and adapted to be arranged tangent to the tapered surface and passing, respectively, through a relevant circumference of the tapered surface. The first and second connectors permit mutual displacement of the first and second reference bodies along the axis of the revolution surfaces and further mutual displacements substantially parallel to a plane perpendicular to said axis.
