目前,我国还有许多工业企业仍在大量使用二、三十年前制造的老设备,这些老设备自动化程度低,机械结构复杂,故障率高,维修困难,加工精度低,产品质量难以保证,工人劳动强度大。由于种种原因,不可能在短期内淘汰这些老设备,而用机电一体化技术来改造老设备,则是一条经济高效的可行之路。在此就机电一体化改造中常用的主要元件的特点及选用作些介 At present, there are still many industrial enterprises in our country that still make heavy use of old equipment manufactured two or three decades ago. These old equipment have low degree of automation, complicated mechanical structure, high failure rate, difficult maintenance, low processing precision, difficult product quality assurance, Workers work hard. Due to various reasons, it is impossible to eliminate these old equipment in a short period of time, and to use electromechanical integration technology to transform old equipment is a viable and cost-effective way. In this mechatronic transformation of the main components commonly used in the characteristics and selection as a medium
