铝合金薄壁件装夹变形分析和控制

Analysis and Control of Clamping Deformation of Aluminum Alloy Thin-Walled Parts

由于铝合金薄壁零件刚性差,在制造过程中受夹具夹紧力的影响,容易产生变形,从而导致零件的加工稳定性差,加工难度大,严重影响产品的加工质量。以自动变速箱油泵盖为研究对象,建立有限元计算模型,进行铝合金薄壁件静结构强度仿真分析,根据计算结果选择最优的装夹方式,优化夹具,为铝合金薄壁件的装夹方式优化提供了理论依据。

Due to the poor rigidity of aluminum alloy thin-walled parts,the parts are easily deformed by the clamping force of the fixture during the manufacturing process,which would lead to processing instability and difficulty of the parts,and seriously affects the quality of product processing.In this artitle,taking the automatic transmission oil pump cover as the research object,simulation analysis of the aluminum alloy thin-walled parts is conducted through establishing the finite element calculation model.According to the calculation results,the optimal clamping mode is selected,and the fixture is optimized so as to provide a theoretical basis for optimizing the clamping mode of the aluminum alloy thin-walled parts.
