The automatic lifting column with the nested hollow lead screws comprises a lead screw assembly, the lead screw assembly comprises a plurality of lead screws which are coaxially nested, and the lead screws are movably provided with nuts; the hollow column assembly comprises a plurality of nested hollow columns, the nuts and the hollow columns are fixed one by one, the mutually nested hollow columns have mutual linear telescopic translation freedom degrees, and the linear telescopic direction of the hollow columns is parallel to the axis direction of the lead screw; the power transmission assembly drives the lead screw to rotate; each lead screw is provided with a hollow cavity for containing the corresponding inner adjacent lead screw, the inner wall of each hollow cavity is provided with a linear edge groove movably assembled with the corresponding inner adjacent lead screw, the linear edge grooves limit the mutual rotation freedom degree of the adjacent lead screws, and the lead screws have the mutual linear telescopic translation freedom degree in the axial direction under the guidance of the linear edge grooves. The lead screw assemblies which are telescopic in a nested mode and rotate synchronously are adopted, the overall linear telescopic translation amount is large, and the device can be applied to the fields of automatic lifting operation, robot mechanical arm extension and the like.
本发明公开了具备嵌套式中空丝杠的自动化升降柱,包括丝杠组件,包括若干根同轴嵌套的丝杠,丝杠活动装配有丝母;空心柱组件,包括若干根嵌套的空心柱,丝母与空心柱逐一固定,相互嵌套的空心柱具备相互的直线伸缩平移自由度,空心柱的直线伸缩方向与丝杠轴线方向平行;动力传输组件,驱动丝杠转动;丝杠具备容纳内部相邻丝杠的中空腔,中空腔的内壁具备与内部相邻丝杠活动装配的直线棱槽,直线棱槽限制相邻丝杠的相互的自转自由度,丝杠具备沿直线棱槽的导向而沿轴向的相互直线伸缩平移自由度。采用此发明采用嵌套伸缩却同步旋转的丝杠组件,整体直线伸缩平移量大,在自动化的升高作业、机器人机械臂延长等领域都能适用。
