The invention relates to a movable testing turntable, in particular to a three-axle turntable capable of moving in all directions. The three-axle turntable comprises a turntable body and a moving platform rotationally connected with the turntable body. The turntable body comprises a rotating rod, a middle ring and an outer ring. The moving platform comprises a base, a plurality of support rods and universal wheels. The outer ring is rotationally mounted on the base. The support rods are evenly distributed on the base circumferentially. The universal wheels are connected to the support rods respectively. Horizontal front-back and left-right translational degrees of freedom are achieved by the aid of the universal wheels. The middle ring is rotationally mounted in the outer ring. The rotating rod serving as a carrier of a to-be-tested object is rotationally mounted in the middle ring. Three rotational degrees of freedom are achieved by rotating the rotating rod relative to the middle ring, rotating the middle ring relative to the outer ring and rotating the outer ring relative to the base. The three-axle turntable has the advantages that driving elements are not needed, the three-axle turntable is simple, convenient and practical in structure, and five degrees of freedom are achieved and can be selected according to testing conditions; the universal wheels at the bottom can be replaced according to needs to facilitate use of the turntable.
