Abstract
An angular divider device is described for worktables, toolholder turrets or the like, in which the number of positions of the subdivision is not predetermined and can be of any desired value, even of very small order such as 1.degree. or even less, without the necessity of positions constrained by mechanical arresting devices such as slots and associated latches, the exactness of the position achieved being determined by the coupling of basic fixed and movable crown gear wheels. The disengagement, the rotation and the succeeding engagement of the movable part, the worktable or toolholder turret, is achieved by the application between the movable part, the fixed part and the movement means, respectively of a brake and of a coupling or clutch which provide alternatively for blocking the movable part in rotation to the fixed part during the phases of disengagement and engagement and for connecting said movable part with the movement means during the rotation phase until the position predetermined by the programme is reached, such position being controlled by a measuring device operating by impulses or the like rotationally connected with said movable part.
