A calibration device for dynamometric tools including a sliding mechanical structure associated with a frame of a test bench, which allows to impart a force and a controlled rotation in such a torque tool, said tool having its clamping tool engaged in a brake placed on the bench. The mechanical structure includes a pair of longitudinal bars which can be connected to the bench, on which at least one guide is mounted transversely, on this guide there is a support which slides in the transverse direction and is provided with a constraint for the tool body, so that the tool is pivoted on the brake with its tool head and can rotate to simulate a tightening of the brake F when the support is moved along this guide.

Calibration device for dynamometric tools

A device for measuring the preloading of a screw during a screwing operation including a container body in which a support is inserted, inside which there is a leadscrew into which such screw is screwed by a tightening tool, at the bottom of such support and connected thereto a transducer being arranged, capable of measuring the traction generated on itself as a result of the compression created by the screwing of the screw into the leadscrew.
