Patent ID: 6952884

Claim:
An apparatus for checking dimensional and geometrical features of a pin, rotating about a geometrical axis of rotation, comprising a Vee-shaped device that defines rest and reference surfaces adapted for cooperating with the pin to be checked, a measuring device, coupled to the Vee-shaped device and including a feeler for contacting the surface of the pin to be checked and performing linear displacements along a measurement direction laying between said rest and reference surfaces of the Vee-shaped device, and a support device for supporting the Vee-shaped device and the measuring device, the support device including a stationary support element, and a coupling mechanism with coupling elements coupled in a movable way to the stationary support element, carrying the Vee-shaped device and allowing displacements of the Vee-shaped device with respect to the stationary support element, wherein said coupling mechanism further includes constraining elements adapted for constraining said displacements of the Vee-shaped device to substantially plain translation displacements.
