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.

A device for measuring a valve seat in a workpiece, wherein the device is elongate along a longitudinal axis and comprises:
- a slide and a guide, the slide being slidaby coupled to the guide for translating in a scanning direction inclined with respect to said longitudinal axis;
- a sensor mounted on the slide and configured to measure a parameter relative to a profile of the valve seat;
- a processing unit connected to the sensor;
- a rotary actuator, defining a longitudinal rotation axis, kinematically connected to the slide for moving the slide along the guide;
- wherein said longitudinal rotation axis of the rotary actuator is substantially parallel to the longitudinal axis of the device and in that the device comprises a transmission assembly interposed between the rotary actuator and the slide, so as to transform a rotary motion about said longitudinal rotation axis of the rotary actuator into a reciprocating linear motion of the slide along the scanning direction.
A method for measuring a valve seat in a workpiece, the valve seat defining a seat axis, comprising the following steps:
- preparing a device elongate along a longitudinal axis and having a sensor configured to measure a parameter relative to a profile of the valve seat and a processing unit for receiving data detected by the sensor;
- positioning the device alongside the seat with the longitudinal axis aligned to the seat axis;
- moving the sensor mounted on a slide by translation in a scanning direction inclined with respect to the longitudinal axis of the device;
- wherein said movement of the sensor comprises the following steps:
- causing a rotary motion of a first transmission element about a longitudinal rotation axis that is parallel to said longitudinal axis by means of a rotary actuator;
- transforming said rotary motion of the first transmission element into a reciprocating linear motion of the slide along the scanning direction.
