【摘要】 采用压电双晶片振子,设计了一种惯性式压电振动送料器,分析了惯性式压电振动送料器的工作原理,建立了压电振子动力学模型,利用Matlab软件分析了振子长度和质量对冲击力与变形量的影响。对料盘中的物料进行了受力分析。制作了送料器样机,并对样机进行试验测试,得到了电压、振幅、频率与送料速度之间的关系曲线,结果表明该送料器在共振条件下具有良好的工作性能,随着电压的增加,振幅与送料速度呈线性增加。相比悬臂梁式压电振动送料器,该送料器具有更大的驱动能力和更小的空间结构。更多还原

【Abstract】 To meet the requirement of smooth convey for light,thin and small product in modern industrial,an inertial piezoelectric vibratory feeder was designed.Its working principle was analyzed and the dynamic model of bimorph vibrator was established.The effect of vibrator length,vibrator mass and impact force on deformation was analyzed in Matlab software.The force of parts in the hopper was analyzed.The prototype of inertial piezoelectric vibration feeder was developed and tested.The relationship among voltage,amplitude,frequency and feeding speed were obtained.The experimental results showed that the proposed vibratory feeder had good performance at resonance.The amplitude and feeding speed increased linearly with the increase of voltage.The proposed vibratory feeder had better driving ability and smaller space compared with the cantilever bimorph piezoelectric vibratory feeder,and had wide prospects.更多还原
