Patent ID: 7760367

Claim:
An optoelectronic apparatus for checking position and/or shape of a mechanical piece with at least one substantially planar surface, the apparatus comprising: a base, a locking and reference system adapted to define and fix the position of said at least one substantially planar surface of the piece to be checked with respect to a reference plane, detecting devices with an optoelectronic system for providing signals indicative of the position of said at least one substantially planar surface of the piece to be checked, a rotation system with a substantially C-shaped support carrying the optoelectronic system and enabling swinging displacements of the optoelectronic system about a longitudinal axis of rotation, the C-shaped support having free ends adapted to perform said swinging displacements, the optoelectronic system comprising an emitter and a receiver coupled to said free ends of the substantially C-shaped support, a processing unit adapted for receiving said signals of the optoelectronic system and providing information relating to the position and/or the shape of said at least one substantially planar surface of the piece to be checked, and a transversal translation system defining a translation axis, transversal with respect to said longitudinal axis of rotation, and enabling translation displacements along said translation axis between the optoelectronic system and the piece to be checked, between different mutual transversal positions at a same transversal section plane.
