Device for the inspecting a threaded element and corresponding inspection method

A dimensional measurement device for a threaded element 1, said device comprising a framework, the framework comprising a first laser line sensor having a first optical measurement direction and a second laser line sensor having a second optical measurement direction, said second optical measurement direction forming a non-zero angle A with the first optical measurement direction in a plane containing the first optical measurement direction, the first laser line sensor and the second laser line sensor being movably mounted on the framework and having at least one measurement path permitting the acquisition of geometric data of the threaded element, said path passing through a calibration gauge and being able to pass through a portion of the threaded element, the device comprising an encoder arranged to determine a position of the first laser line sensor and a position of the second laser line sensor along a main axis (x), and an electronic unit arranged to construct a first partial profile from the first laser line sensor and a second partial profile from the second laser line sensor, the electronic unit being arranged to construct a complete profile from the first partial profile and the second partial profile in dependence on the respective positions of the first laser line sensor and of the second laser line sensor and in dependence on at least one measurement carried out on the calibration gauge.
