The invention discloses a self-adaptive pre-tightening mechanism applied to sleeve unfolding. The self-adaptive pre-tightening mechanism comprises an upper pre-tightening mechanism and a lower pre-tightening mechanism. The self-adaptive mechanism is in transmission with the upper pre-tightening mechanism and the lower pre-tightening mechanism respectively; the input end of the self-adaptive mechanism is in sliding connection with the output end of the power assembly; the output ends of the upper pre-tightening mechanism and the lower pre-tightening mechanism are each provided with a driving assembly, and the power assembly drives the upper pre-tightening mechanism and the lower pre-tightening mechanism through the self-adaption mechanism so as to drive the corresponding driving assemblies to make contact with the inner surface of the sleeve. According to the self-adaptive pre-tightening mechanism, a single power source is used for achieving variable-diameter self-adaption of multiple pre-tightening mechanisms, the upper driving assembly and the lower driving assembly can make contact with the inner surface of a sleeve in any form at the same time, the effective relieving force of the driving assemblies is greatly improved, meanwhile, the structure is simplified, reliability is improved, the scale of a control system is reduced, and cost is reduced; and in cooperation with a differential driving device, reducing pre-tightening and unfolding driving are achieved under the condition that only two motor assemblies are used.
本发明公开了一种应用于套筒展开的自适应预紧机构,包括上预紧机构和下预紧机构;与上预紧机构和下预紧机构分别传动的自适应机构;以及动力组件,自适应机构的输入端与动力组件的输出端滑动连接;上预紧机构和下预紧机构的输出端分别安装驱动组件,动力组件通过自适应机构分别驱动上预紧机构和下预紧机构以驱使对应的驱动组件与套筒内表面接触。本发明的自适应预紧机构使用单动力源实现多预紧机构的变径自适应,可以实现上下驱动组件与任意形式的套筒内表面同时接触,在大幅提高驱动组件有效解除力的同时,简化了结构,提高了可靠性,降低了控制系统规模,降低了成本,配合差速驱动装置,在只使用两台电机组件的情况下实现变径预紧和展开驱动。
