An apparatus for checking the integrity of tools includes an optoelectronic system ( 7 ) with a laser beam ( 21 ), a base ( 6 ) movable along a longitudinal direction (X) for enabling displacements between tool and optoelectronic system and a device for checking the mutual position including, for example, a transducer ( 9,10 ). A sensor ( 22 ) of the optoelectronic system detects the interruption of the beam and, on the basis of the transducer signal at said interruption and on the comparison with a known value, the integrity of the tool is determined. A coupling mechanism ( 24 ) of the optoelectronic system coupled at the base enables oscillations of the former along a transversal reference surface, that define a sensitive delimited area ( 33 ). The oscillations are controlled by means of a motor ( 26 ) and interruptions of the beam are detected and signalled by the sensor the moment that the end of the tool interferes with the sensitive delimited area. |
