An apparatus for checking the diameter of crankpins (18) of a crankshaft (34) in the course of the machining in a grinding machine comprises a first arm (9) rotating with respect to a support (5) arranged on the grinding-wheel slide (1) of the grinding machine, a second arm (12) rotating with respect to the first, a reference device (20) carried by the second arm and a measuring device (16, 17, 40-45) associated with a reference device. A guide device (21), fixed to the reference device (20), enables the apparatus to engage a crankpin, in the course of the orbital motion of the crankpin, and limit the displacements of the first arm and those of the second arm when a control device (28-30) displaces the apparatus to a rest position.
A device for monitoring the diameter of a cylindrical piece in orbital motion about an axis during a grinding thereof by an edge of a rotatable disk-shaped tool mounted on a carriage, said carriage being movable in a transverse direction relative to said axis and said device having a measurement head coupled to a support, said support being provided with a member for contacting the periphery of said piece and being movably mounted relative to a frame in order to follow the orbital motion of said cylindrical piece wherein said frame is secured to said carriage.
An apparatus for checking the diameter of a crankpin in orbital motion about a geometrical axis during a grinding thereof by a grinding wheel mounted on a grinding-wheel slide, said grinding-wheel slide being movable in a transverse direction relative to said geometrical axis and said apparatus having a measurement device coupled to a coupling element of a support device, said coupling element carrying a reference device for contacting the periphery of said crankpin and being movably mounted relative to a support element in order to follow the orbital motion of said crankpin, wherein said support element is secured to said grinding-wheel slide.
