Computer-aided Design of the Lathe Spindle Based on Pro-E

It is assumed that the lathe spindle movement mechanism is composed of 4-axis.Each axis is considered as a sub-structure of the assembly separately equipped with gears and bearings and other parts.3-D entity model of these simple substructures are es tablished respectively using Pro-Engineer,all simple substructures are assembled to a 3-D entity model of the lathe spindle drive.The entire structure kinetic and simulation is studied by using mechanism module in the Pro-E,not only to ensure the accuracy of the lathe spindle drive,but also to greatly improve the efficiency of the design.Using the above method,the lathe spindle designers can optimize the kinematic mechanism in shaping machine rapidly and intiutively,to reduce the costs of research and innovation and improve machine reliability.
