Abstract: A device (1) for measuring a valve seat formed in a piece has an elongate shape and defines a longitudinal axis (A), and includes: a slide (9), slidingly coupled to a guide (11) for translating in a scanning direction (B) inclined to the longitudinal axis; a sensor (10), mounted on the slide for measuring a parameter relating to a profile of the seat; a processing unit connected to the sensor; a rotary actuator (13) defining a longitudinal rotation axis substantially parallel to the longitudinal axis of the device; and a transmission assembly interposed between the rotary actuator and the slide for transforming a rotary motion about a longitudinal rotation axis in a reciprocating linear motion of the slide along the scanning direction.

Abstract: A modular system (1) for checking a valve seat and its associated valve guide in cylinder heads of internal combustion engines comprises a guide and support assembly (10), movable in three directions, which carries one or more electronic gauges (11) and a precentering pin (14) to guide the insertion of the gauge in the valve seat and its associated valve guide, and a tilting table (3) for loading and locating a cylinder head (4). Thanks to the particular structure of a support mechanism (12) connected to the guide and support assembly, the gauge is able to self-position on the valve seat to be checked and to disengage in a checking condition from the guide and support assembly at least in one of the three directions. The tilting table can be adjusted depending on the dimensions and layout of the cylinder head to be checked and includes a swing system (6) to set the tilt of the table as a function of the inclination of the valve seat and its associated valve guide to be checked.
