In order to achieve the hydrocylindertube brush plating automation control, the hydrocylindertube brush plating experimental platform was designed, at the same time, the platform was made possible to provide for study those brush plating optimal parameters. Linefeed and rotation motion of platingpens were driven by two motors respectively. The relative movement velocity of the platingpen with workpiece was adjusted by controlling the motors in a certain range. Meanwhile, a platingpen force application device was devised to adjust and measure the relative pressure of the platingpen with workpiece. Finally, the plating solution circulation control system was designed to achieve plating solution flow controllable and recyclable. Experimental platform is straightforward in operation, stable, very practical and with characteristic of high level of automation, which provides the possibility for the study on repairing process parameters of the hydrocylindertube brush plating.
