精密车床主轴计算机辅助设计

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

将普通车床主轴运动机构视为由四个轴组成,每个轴视为分别装有齿轮和轴承等零件的一个子结构的装配体,利用Pro/E分别建立各子结构的三维实体模型,通过对各子结构装配实现对整个车床主轴传动的三维建模,利用Pro/E软件的Mechanism模块对整个机构进行运动学分析和运动仿真。既保证了车床主轴传动的准确性,也大大提高了设计效率。利用该方法可以使得设计人员快速、直观的对普通车床主轴运动机构进行优化设计,降低机床的研发成本,提高机床的可靠性。

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 df these simple substructures are established 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.
