摘　　要：激光切割机工作台的升降装置为液压系统控制加机械机构导向,实现板材的送料动作。但是原液压系统为调速阀控制,在实际操作中存在调节困难,不易实现平稳动作的问题。本文针对此问题,提出了解决方法。The traditional lifting device for working table of the laser cutting machine has been controlled by hydraulic system and guided by mechanical part, which can realize the feeding process of the sheet metal. But the hydraulic system has been controlled by speed control valve, which makes the adjustment difficult in stable movement. The solution has been put forward in the text.
