| 针对目前传统钻床钻削微孔存在的局限性，基于超声振动钻削基本理论，课题组设计了一套超声轴向振动钻削装置，用于对微孔进行钻削加工。并基于ANSYS软件运用有限元法对超声振动装置的核心微孔部件变幅杆进行动力学特性仿真研究，得到变幅杆的固有频率和振型以及在变幅杆达到共振时的自由端振幅，从而获得变幅杆的振幅放大系数等参数，设计了高振幅放大比变幅杆。该超声振动钻削装置可直接安装在摇臂钻床主轴上进行微孔的钻削加工，并得到高质量的微孔。该设计有效解决了传统钻削的不足。 |

| Aiming at the defects existing in the traditional drilling machine in drilling micro holes, and based on the principle of vibration drilling, a set of ultrasonic axial vibration drilling device was designed, which could be used for vibration drilling of micro holes. The FEM software ANSYS was used in the simulation of the the horn's dynamic characteristics. The natural frequency and vibration mode of the horn were calculated and achieved the amplitude of the free end of the horn in the resonance state, and the amplitude amplification ratio and the other parameters were obtained. A high amplitude amplification horn was designed. The ultrasonic vibration drilling device could be directly installed in the radial drilling machine spindle for the micro hole drilling process, and the high quality of the micro hole was gotten. This design overcomes the shortcomings of traditional drilling. |
