    • A motorized leveling stage capable of adjusting the angular position of a work piece relative to a reference plane includes an upper stage, a lower stage, and a hinge coupling corresponding edges of the two stages together for relative pivotal movement of the stages. A first spring pivotally biases the upper and lower stages toward each other about the axis of the hinge. A slide is disposed for sliding movement on an upper surface of the lower stage in a direction generally perpendicular to the hinge axis. The slide includes an upper surface defining an inclined plane disposed in sliding abutment with a lower surface of the upper stage such that movement of the slide toward and away from the hinge respectively raises and lowers the upper stage relative to the lower stage. A motorized drive assembly is operable to control movement of the slide relative to the hinge.
    • 能够调节工件相对于参考平面的角位置的电动调平台包括上段,下段以及将两级的对应边缘联接在一起的铰链,用于阶段的相对枢转运动。 第一弹簧围绕铰链的轴线彼此朝向彼此枢转地偏压上层和下层。 设置滑块,用于在大致垂直于铰链轴线的方向上在下层的上表面上滑动运动。 滑动件包括限定倾斜平面的上表面,该倾斜平面设置成与上部台阶的下表面滑动邻接,使得滑动件朝向和远离铰链的运动分别升高并降低上部相对于下部平台。 电动驱动组件可操作以控制滑架相对于铰链的运动。
