Parallel satellite antenna posture adjustment device

The utility model provides a parallel satellite antenna posture adjustment device, adopts a no -coupling two to rotate parallel mechanism, including allocating the platform, move the platform and connecting three branch's motion chains that allocate the platform and move the platform. Wherein article one branch motion chain contains four pairs, removes vicely and the fourth universal joint for first revolute pair, second universal joint, third from allocating the platform in proper order to moving arranging of platform. Second branch motion chain contains three pair, arranges in proper order to what move the platform that the second removes vicely and the third universal joint for first arc removes vicely from allocating the platform. Third strip branch motion chain includes the revolute pair that two axis intersected vertically. The antenna is installed on moving the platform through the bolt, two solitary control antenna's of servo motor difference the angle of elevation and azimuthto the realization is adj
