Electrochemical polishing device for inner surface of long and thin pipeline

Abstract

The invention provides an electrochemical polishing device for the inner surface of a long and thin pipeline and belongs to the field of precise non-traditional machining. The structure of the electrochemical polishing device comprises a control terminal module, a power supply system, a monitoring module and a processing main body, wherein the control terminal module has a function of displaying each current environmental parameter of the device; a monitoring system comprises the monitoring module for monitoring each environmental parameter. The electrochemical polishing device disclosed by the invention adopts a tool electrode with a spiral slot structure; during polishing, the tool electrode performs axial linear reciprocating movement and rotary motion to realize full controllable perturbation of a fluid inside the pipeline and take away air bubbles and processing precipitates generated during processing, so that electrolytic reaction on the inner surface of the long and thin pipeline is performed uniformly; a vacuum pump is used for sucking out electrolyte from the bottom end of the pipeline so as to prevent ejection of the electrolyte during processing; the electrolyte is fully purified by an electrolyte circulating filtration system, so the service life of the electrolyte is prolonged; the temperature of the electrolyte can be regulated and controlled in real time by an electrolyte heating system, so that the polishing effect is improved.
