某总装车间重载吊具柔性提升方案研究

Research on Flexible Lifting Scheme for Heavy Load Spreader in an Assembly Workshop

某总装车间导入的新车型与原车型的车身工艺孔位置差异较大,现有吊具无法满足生产需求。为此,提出了一种更换吊具支点和后托臂实现2种平台车型共线生产的方案。该方案大幅降低了吊具的改造工作量和对相关设备的影响,缩短了吊具改造周期,降低了新车型融入的成本。基于ANSYS仿真平台分析改造后的吊具在静态工况和动态工况下的刚度、强度,对吊具样件进行在线空载运行测试和带车装配测试。结果表明:改造后的吊具能够满足2种平台车型共线生产需求。

Due to the significant difference in the position of the body pivot holes between the new model produced in an assembly workshop and the original one,the existing spreader can’t meet the production needs.Therefore,a solution is proposed to achieve co-production of 2 platform vehicle models by replacing the lifting fulcrum and rear support arm.This solution greatly reduces the modification workload of spreader and the impact on related equipment,shortens the spreader modification cycle,and reduces the cost in integrating new vehicle models.Based on the ANSYS simulation platform,the stiffness and strength analysis of the modified spreader under static and dynamic working conditions are carried out.Online no-load operation testing and vehicle assembly testing are carried out on the spreader samples.The results show that the modified spreader can meet the co-production needs of this dual platform models.
