| 中文摘要: |
| 针对现有外圆磨床夹头不能调心易导致过定位和自动化水平不高的问题，将调心卡爪应用到外圆磨床夹头上，设计出一种能自动调整
卡爪回转中心的新型夹头。夹头由电机驱动，可实现自动夹紧工件、带动工件回转和自动松开工件等多重功能。基于虚拟样机技术完成夹头的仿真分析，将Creo
软件中建立的夹头模型导入ADAMS软件，结合夹头的受力情况，分别对夹头与工件同心转动和偏心转动2种情况下夹头夹紧和松开工件的过程进行仿真。仿真结
果表明2种情况下夹头均能快速地夹紧工件，稳定地带动工件绕顶尖回转轴线转动和快速地松开工件。文中夹头能保证工件回转轴线与顶尖回转轴线重合，提高
了外圆磨夹头的定心精度和自动化水平。 |

| In view of the problem that the existing external cylindrical grinder chuck cannot be adjusted, which will lead to over positioning and the low
automation level. A new kind of chuck which can automatically adjust the rotary center was designed by applying the self aligning jaw to the chuck of external cylindrical grinder. The
chuck was driven by motor, thus the functions such as workpiece clamping, releasing and turning can be realized. Based on the virtual prototype technology to complete the simulation
analysis of the chuck, the model of chuck established in Creo software was imported into the ADAMS software. Combined with the force of the chuck, the process of clamping and
releasing the workpiece under the condition of concentric rotation and eccentric rotation of the chuck and the workpiece was simulated respectively. The results show that in both cases, the
chuck can quickly clamp the workpiece, stably move the workpiece around the top rotation axis and quickly release the workpiece. It can be assured that the rotation axis of workpiece
coincides with that of the center and the centering accuracy and automation level of the external cylindrical grinder chuck can be improved. |
