摘　　要：在传统的微型机械结构设计方法中,由于对微型机械构件的加工、切割精度低,导致设计的微型机械结构的品质不够高。为此,将变焦激光切割技术应用在微型机械结构设计中。通过分析长度尺寸对微型机械结构的影响,将变焦激光切割技术应用其中,通过自动调整激光切割器的焦距,使激光切割器找到合适的焦点位置,并提高激光振镜的扫描精度、调整聚焦光斑大小,以此提高微型机械结构的设计品质。通过对比实验,与其他3种传统的微型机械结构设计方法相比,实验结果表明,提出的利用变焦激光切割技术的微型机械结构设计方法的切割精度更高,切割效果更好。将变焦激光切割技术应用在微型机械结构设计中,能够明显提高微型机械结构的设计水平,提升微型机械结构的品质。In the traditional design method of micro-mechanical structure,due to the low machining and cutting accuracy of micro-mechanical components,the quality of micro-mechanical structure designed is not high enough.Therefore,the zoom laser cutting technology is applied in the design of micro-mechanical structure.By analyzing the influence of the length dimension on the micro-mechanical structure,the zoom laser cutting technology is applied.By automatically adjusting the focal length of the laser cutter,the laser cutter can find a suitable focus position.By improving the scanning precision of the laser galvanometer,and adjusting the spot size of focus,the design quality of the micro-mechanical structure is improved.Compared with other three traditional micro-mechanical structure design methods,the experimental results show that the proposed micro-mechanical structure design method using zoom laser cutting technology has higher cutting accuracy and better cutting effect.The application of zoom laser cutting technology in micro-mechanical structure design can obviously improve the design level of micro-mechanical structure and the quality of micro-mechanical structure.
