The invention discloses a pneumatic synchronous lifting structure. The structure is mainly composed of a rack, a lifting frame, a transverse pull rod, a synchronous shaft, a rocker arm, an expansion sleeve, air cylinders, an air cylinder support, a connecting rod, an insert bearing and the like. A multi-connecting-rod mechanism and the synchronous shaft are arranged, the multiple air cylinders drive one component to move at the same time, the multi-connecting-rod mechanism and the synchronous shaft are used for conducting forced synchronization on the actions of the multiple air cylinders, mechanism jamming caused by asynchronous actions of the multiple air cylinders can be avoided, the action is reliable, the structure is simple, and implementation is easy.
一种气动同步升降结构,其主要结构由机架、升降架、横拉杆、同步轴、摇臂、胀紧套、气缸、气缸支架、连杆、外球面轴承等组成。带有多连杆机构和同步轴,多个气缸同时带动一个部件运动,利用多连杆机构和同步轴将多个气缸的动作进行强制同步,可以避免多个气缸动作不同步带来的机构卡死,动作可靠,且结构简单,易于实现。
