摘要
光纤研磨机采用具有公转、自转复合的转台运动机构实现光纤端面的均匀研磨性能,适用于大批量生产光纤连接器件。在光纤端面高精度、高效率研磨抛光过程中,应使研磨盘具有合理的运动轨迹及恒定的压力保持,为实现这一目的,本论文针对研发的光纤研磨机进行了控制电路及气动加压系统设计。采用变频调速器对主运动电机转速实现无级调整,低成本条件下,采用继电器控制电路和气动系统完成加工过程中的压力控制。对所完成的设计经FluidSIM软件仿真及实验验证证明设计合理可靠,可实现所需功能要求,这对研磨机的开发及实际应用提供了保证。

Abstract
Fiber muller is used in the mass product of fiber linkers which has the uniformity rubbing character to the fiber flank with the revolution and rotation turret. When the fiber optics flank is rubbed and polished subtly and efficiently, we should make the rubbing dish own reasonable sport track and keep the stable pressure, in order to realize this target, this thesis aims at design the electric circuit control and pneumatic pressurization system of fiber optics muller. Adopts frequency changed machine to realize no class adjustment to the turning speed of the major electrical engineering, and in the condition of low cost adopts electric appliances to control electric circuit and the pneumatic system to plish the pressure control in the process of the processing. The finished design was certificated by the FluidSIM software really imitate and the experiment, which is verified reasonably and credibility, the design can realize the requested function, which offers the assurance for the development and actual application of the muller.
