摘要: 提出了侧向斜拉压电驱动供料器的新结构,其驱动源的安装角度为与水平夹角60°,与垂方向夹角12°,产生圆周和垂直两个自由度的驱动力,提高了供料器的供料性能。在分析其驱动结构和物料运动性能后,利用了Ansys软件对整机进行有限元分析,优化了驱动结构并获得了整机的共振频率。分析了驱动频率与给料速度的关系、驱动电压与给料速度的关系以及驱动输出频率与输出电流的关系。Abstract: This article has proposed a new structure of lateral tensile piezoelectric driving feeder, which is based on the research on advanced technology of foreign piezoelectric feeders. The installing angles of the feeder's driving source are 60 degrees with the horizontal and 12 degrees with the vertical, that has produced driving forces in two degrees of freedom-circumferential and vertical directions, and that improved the feeding performance of the feeder. After analyzing the driving structure and parts' movement performance, the finite element software Ansys is applied to analyze the whole machine, that, as a result, optimizing the driving structure and getting the whole machine's resonance frequency. According to the experimental study, we analyzed the relationships between the driving fre-quency and feeding speed, the driving voltage and feeding speed, and the driving output frequency and output cur-rent. Compared with the electromagnetic vibration feeders, the piezoelectric vibration feeders have improved the feeding performance greatly and their energy-saving effect is remarkable.
