The invention discloses a two-degree-of-freedom and rotational
motion control platform for stage performance, and relates to the technical field of aluminum bar rolling. The device comprises a supporting table, a lamplight
assembly is fixedly connected to the position, close to one side, of the top end of the supporting table, an inner groove is formed in the position, close to the center, of the interior of the supporting table, a control
assembly is arranged at the position, located in the inner groove, of the top end of the supporting table, the lamplight
assembly comprises two base columns, and the bottom ends of the base columns are fixedly connected with the top end of the supporting table; a top plate is fixedly connected between the top ends of the two base columns, flash lamps are symmetrically and fixedly connected to the positions, close to the two sides, of the bottom end of the top plate, toothed plates are symmetrically and fixedly connected to the centers of the two side ends of the inner groove, and the control assembly comprises a supporting plate. According to the lifting device for the stage, a motor is operated, then under the mutual cooperation of a transmission shaft, two sets of second synchronous wheels, a second synchronous belt, two lead screws, a top column and a mounting box, a supporting plate and a control assembly below the supporting plate are driven to ascend, and then lifting operation of the whole stage can be achieved.
