The invention provides a roller bed pneumatic lifting device and a lifting control method thereof. The device is installed on a fixed base and comprises a pneumatic lifting mechanism and an anti-falling supporting mechanism. The pneumatic lifting mechanism comprises a jacking air cylinder, a guide mechanism and a synchronizing mechanism, the jacking air cylinder drives the roller bed fixing bracket to ascend and descend, and the guide mechanism and the synchronizing mechanism guarantee that the roller bed fixing bracket moves stably and accurately. And when the pneumatic lifting device has an accident, the anti-falling supporting mechanism can support the roller bed fixing bracket to prevent the roller bed from falling. The roller bed lifting device is simple and compact in structure, stable in operation, convenient to maintain and overhaul and suitable for a welding station needing roller bed lifting, and positioning of a vehicle body is achieved through falling of the roller bed.
本发明提供了一种辊床气动升降装置及其升降控制方法;安装在固定底座上,包括气动升降机构和防跌支撑机构。气动升降机构包括顶升气缸、导向机构和同步机构,顶升气缸带动辊床固定托架升降,导向机构和同步机构保证辊床固定托架平稳、准确地运动。防跌支撑机构在气动升降装置出现意外时,能够托住辊床固定托架,防止辊床跌落。本发明结构简单、紧凑,运行稳定,维护和检修方便,适用于需要辊床升降的焊装工位,通过辊床的降落,实现车身的定位。
