成都科技大学于1981年4月28日至29日,召开了该校研制的开关型闭环数控通用机械手的技术评议会。参加会议的有四川省科委、省机械局、省高教局、成都市科委以及有关高等院校、科研所、工厂等18个单位40名代表。会议期间,代表们听取了方案介绍,观看了机械手按编制的程序主动夹着墨笔写“中”字等动作表演,进行了定位精度测试。与会代表经过讨论认为:该机械手采用闭环简易数控电磁换向开关阀,实现
Chengdu University of Technology on April 28, 1981 to 29, held the school developed a closed-loop CNC closed-end CNC mechanical manipulator technical council. There were 40 representatives from 18 units including Sichuan Science and Technology Commission, Provincial Bureau of Machinery, Provincial Bureau of Higher Education, Chengdu Science and Technology Commission, and relevant institutions of higher learning, research institutes and factories. During the meeting, delegates listened to the introduction of the program and watched the robots perform the performance tests of “Zhong” with the ink pen in their own hands. After discussion, the delegates considered that the manipulator adopts closed-loop simple numerical control electromagnetic reversing on-off valve to realize
