东风4型交-直流电传动内燃机车的硅整流元件上有多种电镀零件,如铜压块、散热器铜头等要镀银,散热片等要镀镍,弹簧端板等又要镀锌。过去,人工操作,效率低,质量也不稳定。大连机车车辆工厂硅元件工人,针对这一薄弱环节,建成了电镀自动线。整条电镀线由电源、镀槽、机械手、自动上下装置及电气控制系统等组成。机械手为可行走的圆柱坐标式,有升降、回转、前后行走三个自由度,液压驱动。装有工件的挂具或滚镀桶由机械手完成放入 Dongfeng 4 AC-DC diesel locomotive rectifier components have a variety of electroplating parts, such as copper briquettes, copper and other heat sinks to be silver-plated, heat sinks and other nickel to be plated, the spring end plate and then galvanized. In the past, manual operation was inefficient and the quality was not stable. Dalian locomotive and rolling stock factory silicon component workers, for this weakness, built an automatic plating line. The entire plating line by the power, plating tank, manipulator, automatic up and down devices and electrical control systems and other components. Manipulator is walkable cylindric coordinate system, with lifting, turning, three degrees of freedom before and after walking, hydraulic drive. With the workpiece hanging or barrel barrel finished by the robot into
