Design of Loading and Unloading Control System for Reaming and Honing of Sliding Bearings

Loading and unloading control system for reaming and honing of sliding bearings mainly consists of loading unit, conveying unit and unloading unit, and has the functions of material identification, workpiece alignment, mechanical arm conveying and material unloading. This paper analyzes pneumatic control principle in detail and designs a control system based on Mitsubishi PLC. Thereinto, linear movement of mechanical arm and workpiece revolution & alignment are just implemented by servo system. It's indicated that this system is in reliable operation and conforms to production requirement after online debugging and application on the production line.
