| 为了提高射流电解加工小孔的效率及质量，提出了一种压电超声波换能器配合锥形电解液腔室的装置，将超声波引入电解液中，对射流电解加工存在的缺陷进行弥补。搭建了超声辅助射流电解加工装置，分析了其加工原理。对模型进行了声场仿真和射流电解加工仿真，初步验证了超声辅助效果。实验验证了超声波对射流电解加工的加工速率、小孔形状的辅助效果，结果表明：在多组NaNO3电解液浓度、液压泵转速条件下，1.5 min内超声波对射流电解加工的加工速率可提高9%-15%；同时超声波对射流电解加工的过切现象有所改善。 |

| In order to improve the machining efficiency and quality of small holes, and make up some defects of the electrochemical jet machining, an ultrasonic assisted electrochemical jet machining device including the piezoelectric transducer and the conical cavit is proposed. The ultrasonic-assisted electrochemical jet machining device is built, and its machining principle is analyzed. The sound field simulation and electrochemical jet machining simulation are carried out, and the ultrasonic assisted effect is preliminarily verified. The experiment results verify the assisted effect of ultrasonic wave on the machining rate and shape of small hole of the electrochemical jet machining. The results show that under the conditions of multiple groups of NaNO3 electrolyte concentration and hydraulic pump speed, the machining rate of ultrasonic assisted electrochemical jet machining can be increased by 9%-15% within 1.5 min. At the same time, ultrasonic wave improves the overcutting phenomenon of electrochemical jet machining. |
