The purpose of the invention is to replace the manual targeting coordinates longitudinal members segments-dimensional form with precious by positioning dots. This is achieved by motorized positioning device comprising a frame (1) with displaceable in the vertical direction and rotatably in the horizontal plane of the mounted attachment (2), at the upper end with a horizontally oriented rotatable plate (3) from which the of column brackets (4) pivotally mounted cradle (5) to which are fastened the top wall extending arms (6), wherein the stored pivoting arm (7) for receiving longitudinal members spaced segment-shaped path. The stand (1) is fixed to the cross table, formed by the lower and upper cross slide (8, 9) Drive (81, 91). The cradle (5) and the arm (7) are provided with actuators (51, 71) for controlling the rocking motion. Actuators (11, 51, 71, 81, 91) are formed by electric motors and / or hydraulic motors, and are preferably connected to the control system controlled by a computer program. |
