A LARGE SCREEN COORDINATING EQUIPMENT WITH SIX DEGREES OF FREEDOM

摘要

The invention discloses a large-sized display screen coordinating device in six degrees of freedom. It comprises three identical mechanical arms disposed equidistantly and parallelly to one another. In each mechanical arm, a column (2) pivoting kinematic pair that can pivot about axis Y is provided respectively at the top and bottom ends of the vertically provided support column; one end of a tension arm (5) is provided on a side face of the vertical support column via a tension arm pivoting kinematic pair (4); a first pivoted arm (9) is fitted and connected to the free end of the tension arm via a first pivoting kinematic pair (8); a second pivoted arm (11) is fitted and connected to the free end of the first pivoted arm via a second pivoting kinematic pair (10); a third pivoted arm (14) is fitted and connected to the free end of the second pivoted arm via a third pivoting kinematic pair (12); and the third pivoted arm is fitted and connected to a display screen via a display screen pivoting kinematic pair (13).
