用于悬浮升降平台的五自由度铰链
摘要：
本发明属于连接结构设计，具体公开了一种用于悬浮升降平台的五自由度铰链。它包括圆盘形的上球碗和下球碗，在上球碗、下球碗的中心设有球孔，在球孔内设有球头；所述的下球碗的下方设有下止动板，所述的上球碗的上方设有上止动板。由上球碗、下球碗和球头组成的球面接头可提供三个自由度的转动，确保电动缸推杆的直线运动与平台升降部件直线运动存在偏转角度时可正常工作，不会发生卡死或迟滞现象；同时提供了垂直于电动缸直线运动的运动平面的两个自由度的运动，有效解决了电动缸推杆的直线运动与平台升降部件直线运动不重合的现象。
摘要（英）：

The invention belongs to a design on connecting structures, and concretely discloses a five-DOF (degree of freedoms) hinge for suspending a hoistable platform. The five-DOF hinge comprises a disc-shaped upper spheric bowl and a disc-shaped lower spheric bowl, wherein the centers of the upper spheric bowl and the lower spheric bowl are respectively provided with a spheric hole, and the inside of the spheric hole is provided with a spheric head; a lower check plate is arranged below the lower spheric bowl, and an upper check plate is arranged above the upper spheric bowl. A spherical joint consisting of the upper spheric bowl, the lower spheric bowl and the spheric head can provide a three-DOF rotation, thereby ensuring that the hinge can run normally and no jammed or lagging phenomenon occurs when a deflection angle exists between the linear motion of a push rod of an electric cylinder and the linear motion of a hoistable component of the platform; meanwhile, a two-DOF rotation of a motion plane perpendicular to the linear motion of the electric cylinder is provided, thereby effectively solving a phenomenon that the linear motion of a push rod of an electric cylinder is not coincided with the linear motion of the hoistable component of the platform.
