ABSTRACT:
The device, shown associated with a bore measuring machine, comprises two elements in engagement in the form of a bolt (20) and a nut (21) of reversible relative axial rotation and displacement. The bolt (20) is a threaded cylindrical sleeve mounted coaxial to the measurement rod (4) of the machine and with free rotation between two stops (9, 23) thereof, and the nut (21) is formed by an inner thread on the cylindrical body (1) of the machine. The force of friction developed by the relative bolt-nut rotation is adapted to yield to at least the pressure of the return spring (7) of the measurement rod and to constitute a brake for modulating the speed of the displacements in both directions of the measurement rod (4) in the body of the machine.
