Abstract
An apparatus for checking the diameter of crankpins () of a crankshaft in orbital motion about a geometrical axis in a numerical control machine tool includes a V-shaped reference device (), a measuring device () and a support device () fixed to the tool holding slide () that movably supports the reference device and the measuring device. A control device () for controlling automatic displacements of the apparatus towards and away from a checking condition, includes a programmable electric motor () and a transmission mechanism (). The programmable electric motor is programmed to define a start position in which the automatic displacement of the apparatus away from the checking condition can be stopped, for instance a rest position or an intermediate position between the rest position and the checking condition. The programmable electric motor is also programmed to define a displacement speed and a checking method includes steps for controlling the automatic displacements towards the checking condition.
