Electrolysis-electrodeposition machining device and method for repairing SLM formed part

Abstract

The invention discloses an electrolysis-electrodeposition machining device for repairing an SLM formed part. The electrolysis-electrodeposition machining device comprises a first electromagnetic reversing control valve, a second electromagnetic reversing control valve, a small six-axis mechanical arm, a computer control system and a workbench. The working positions of the first electromagnetic reversing control valve and the second electromagnetic reversing control valve are each provided with four oil ports A, B, P and T. A nozzle is fixed to the front end of the small six-axis mechanical arm, and the tail of the nozzle is connected with the oil port B of the first electromagnetic reversing control valve through a liquid conveying pipeline. The oil ports T, P and A of the first electromagnetic reversing control valve are connected with a first solution tank, a second solution tank and a third solution tank through liquid conveying pipelines correspondingly, and the first solution tank, the second solution tank and the third solution tank are connected with the oil ports T, P and A of the second electromagnetic reversing control valve through liquid conveying pipelines correspondingly. Based on the device, the surface defects of the formed part are repaired, and jet electrolysis machining and jet electrodeposition machining are conducted on the surface of the formed part. Through the combination of the two machining modes, the surface quality of the SLM formed part is improved.
