图 为课题组设计和构建的具有自主知识产权的电化学微增材制造系统示意图。该系统可以实现内孔类和杆类零件的自动化电电沉积再制造，包括镀镀液供给分配装置、外圆专用镀笔、内孔专用镀笔和支架。待再制造工件安装在工件定位销处，根据工件的形状和尺寸设计镀槽，镀笔插入镀槽中，镀笔的刷板紧贴工件作摩擦运动，在电沉积过程中，工件为阴极，镀笔为阳极，采用新设计的装置可以制备出组织致密、表面平整光亮的镀层。该装置通过更换镀笔和工件，可以实现内孔类零件和外圆类零件的再制造。电机、电源、供液泵等通过数控设备控制，易于实现自动化操作。另外，安装凸轮轴可以把旋转运动变为直线运动，实现平面零件的再制造。

Figure shows the schematic diagram of the electrochemical micro-additive manufacturing system with independent intellectual property designed and built by the group. The system can realize automated electrodeposition remanufacturing of bore and rod parts, including a plating solution supply and distribution device, a special plating pen for external circles, a special plating pen for internal holes and a holder. The workpiece to be remanufactured is mounted at the workpiece positioning pin, the plating tank is designed according to the shape and size of the workpiece, the plating pen is inserted into the plating tank, the brush plate of the plating pen is pressed against the workpiece for frictional movement, the workpiece is the cathode and the plating pen is the anode during the electrodeposition process, and the newly designed device can produce a dense, smooth and bright plating layer. By replacing the plating pen and workpiece, the device can realize the remanufacture of bore parts and external round parts. The motor, power supply, and liquid supply pump are controlled by CNC equipment, making it easy to automate the operation. In addition, the installation of camshaft can change the rotary motion into linear motion and realize the remanufacture of flat parts.
