分析了数控转塔冲床X-Y工作台的结构设计和传动方式,应用ANSYS软件对数控转塔冲床X-Y工作台的关键零部件进行有限元分析与计算。通过对支架的静力学分析可知,支架的最大位移量为0.0551 mm,在传动过程中对系统的影响可忽略不计,达到设计要求的精度。根据滚珠丝杠的模态分析可知,滚珠丝杠的工作频率远低于其固有频率范围,故滚珠丝杠不会发生共振现象。通过对底座横梁受力情况进行瞬态分析,得出横梁的最大位移符合工作要求。 The structure design and transmission mode of X-Y table of CNC turret punch press are analyzed. The key components of X-Y table of CNC turret punch press are analyzed and calculated by ANSYS software. According to the static analysis of the bracket, the maximum displacement of the bracket is 0.0551 mm. The influence on the system in the transmission process is negligible, and the precision required by the design is reached. According to the modal analysis of the ball screw we can see that the operating frequency of the ball screw is much lower than its natural frequency range, so the ball screw resonance will not occur. Through the transient analysis of the force of the base beam, it is concluded that the maximum displacement of the beam meets the working requirements.
