| 目的 研究薄壁环形机械包装件装夹变形问题，针对此类薄壁环形包装件加工过程中存在的极易变形问题，以求优化环形包装件装夹方案，避免零件弹塑性变形，从而避免组合件报废。方法 利用有限元分析法，基于ANSYS对薄壁环形包装件进行研究，结合“载荷增量法”，设计铣削预紧力施加方案，研究预紧力载荷对包装过程中零件铣削变形的影响规律。结果 仿真结果显示，粗加工筋壁位置处施加预紧力，精加工型槽处施加压紧力，结合限力矩扳手施加预紧力可有效减少薄壁支撑环变形量。结论 试验研究结论表明，使用限力矩扳手将预紧力控制在有效范围内，作用点位置在筋壁处可有效避免薄壁件薄壁支撑环变形，从而提高环形包装件产品质量。 |

| The work aims to study the clamping deformation of thin-walled annular mechanical packaging parts, in order to optimize the clamping scheme of annular packaging parts to avoid elastic-plastic deformation of the parts during the machining process of such thin-walled annular packaging parts, thus avoiding the scrapping of the assembled parts. The finite element analysis method was used to investigate the behavior of thin-walled annular packaging parts based on ANSYS. Additionally, combined with the "load increment method", a milling preload application scheme was designed to examine the impact of preload on the milling deformation of the parts during the packaging process. The simulation results demonstrated that applying preload force to the roughing bar wall position, employing compression force in the finishing groove, and combining preload force with a torque-limiting wrench effectively minimized the deformation of the thin-walled support ring. The experimental study suggests that employing a torque-limiting wrench to regulate the preload force within the appropriate range, with the action point positioned at the bar wall, can effectively prevent deformation of the thin-walled support ring. In turn, this enhances the product quality of the annular packaging parts. |
