Abstract

The invention relates to a longitudinal-torsional composite piezoelectric vibration disc, a method and application, and belongs to the technical field of vibration disc study. The piezoelectric vibration disc comprises a piezoelectric ceramic pile, a slotted circular pipe and a mass block base. The piezoelectric ceramic pile serves as a shock excitation source, vibration is transmitted through theslotted circular pipe, and proper modality and frequency are found through simulation via adjustment on slotted circular pipe parameters and the finite element analysis. Meanwhile, ultrasonic vibration amplitude and power can be controlled by changing applied voltage so that the longitudinal-torsional composite piezoelectric vibration disc can be applicable to assembling of components different in mass. According to the longitudinal-torsional composite piezoelectric vibration disc, the method and the application, the output amplitude can be controlled by adjusting the output voltage, accordingly, the feeding speed can be adjusted, different amplitudes can be provided, the conveyed material mass range is wide, the power is large, and the vibration disc feeding yield is improved; and the longitudinal-torsional composite piezoelectric vibration disc is suitable for large-size material conveying, low in work frequency, high in treating capability and relatively low in power consumption.

Description

technical field [0001] The invention belongs to the technical field of vibrating disk research, and relates to a longitudinal-torsion composite piezoelectric vibration disk, a longitudinal-torsion composite piezoelectric vibration method and its application in a piezoelectric feeding device. Background technique [0002] The vibrating plate is a new type of vibrating machine evolved from the vibrating feeder at the beginning. It is the main component to solve the problem of automatic feeding of parts. Through vibration, the disordered workpieces are automatically and orderly arranged in order and accurately transported to the next process. The vibrating feeder replaces the tedious manual sorting, and can sort out unqualified workpieces to improve production efficiency; on some fully automated mechanical equipment, the vibrating plate can partially or completely replace manual work to achieve rapid production, accurate and stable automatic loading and unloading material and ...
