Abstract:
An optoelectronic apparatus for at least one of dimension and shape checking of pieces with a plurality of substantially planar and mutually parallel surfaces, comprising:a base; a locking and referring system for a piece to be checked, a detector with an optoelectronic system for providing signals indicative of the dimensions of the piece to be checked; a rotary structure, one of said locking and referring system and optoelectronic system being coupled to the rotary structure, and a system for the longitudinal displacement, that is coupled to the base and defines a longitudinal axis, the rotary structure or the locking and referring system being fixed to the longitudinal displacement system for allowing longitudinal translation and reciprocal rotational displacements about the longitudinal axis between said piece and said optoelectronic system, the optoelectronic system providing said signals in the course of said reciprocal rotational displacements, wherein the locking and referring system is adapted for defining the arrangement of the piece, the latter having a complex tridimensional shape with wings defining said planar surfaces, in such a way so that said plurality of planar surfaces substantially lie on planes parallel to said longitudinal axis, the optoelectronic system being adapted to provide, in the course of said reciprocal rotational displacements, signals indicative of the position of the wings.
