关于电液集成块的使用,在本刊1988年第一期中已有说明。本文只对用CPU电路来控制电液集成块液压系统进行讨论。我们用电液集成块改造了一台由上海仪表枫床厂生产的CG6125液压车床。此种型号车床的拖板,直接由油缸推动小刀架作纵向运动;液压马达通过蜗轮蜗杆传动,使小刀架作横向运动。我们折除了原来手动操作的液压阀,用电液集成块组成的液压系统取代之。并自行设计和组装出与之相配套的微处理器控制电路(即CPU电路),来控制该液压系统的动作。使一台手动操作的液压车床,变成一台由电脑控制的数控车床。该电液
On the use of electro-hydraulic manifold, in the first issue of 1988 has been described. This article discusses the use of CPU circuitry to control electrohydraulic manifold hydraulic systems. We converted a CG6125 hydraulic lathe manufactured by Shanghai Instrument Feng Bed Co., Ltd with electro-hydraulic manifold. This type of lathe drag plate, directly by the cylinder to promote the vertical movement of the knife holder; hydraulic motor worm gear drive, so that the knife holder for lateral movement. We cut off the original manual operation of the hydraulic valve, hydraulic system composed of electro-hydraulic manifold replaced. And design and assemble their own microprocessor control circuit (ie, CPU circuit) to control the operation of the hydraulic system. Turn a manually operated hydraulic lathe into a computer controlled CNC lathe. The electro-hydraulic
