Abstract
Spiral Vibrating Feeder is a kind of common equipment in Machining Automation. Traditional theoretical analysis of spiral vibrating feeder is based on the dynamic model of vertical vibration, which can not really reflect the working condition of the system. On the basis of explaining the working principle of the spiral vibration feeder system, a three-degree-of-freedom vibration mechanics model of the system is established. The theoretical formulas of the amplitude-frequency characteristics of the system are deduced and analyzed, and Taking PEF120A feeding system as an example, the amplitude-frequency characteristics of the system are analyzed comprehensively. The experiments prove that the re-established system model is closer to the actual situation, which will lay a good theoretical foundation for the design of vibrating feeder for conveying precision components.
