数控铣削中心设计——主传动系统设计

CNC milling center design-main drive system designAbstractThe main drive system of CNC milling center is the power system of the mainmovement of CNC milling center.This paper mainly Outlines the main drive system design ofCNC milling center,including the spindle activation,termination,direction and speedselection.This design mainly USES SolidWorks for 3d modeling design,preliminarily selectsthe appropriate motor and bearing,designs the main shaft body and the corresponding sealingdevice,tool clamping and chip blowing device and the spindle quasi-stop device,graduallydesigns each part,finally carries on the assembly.Use the equivalent diameter method to check the drive shaft and analyze the stressthrough simulation,and then analyzed the final data to formulate improvement plans forstructural optimization.Key words:CNC milling center;Mechanical structure design;Finite element analysis;Maindrive system
