超大型薄壁主轴件加工技术研究

摘要

The major machining difficulties for a super-large-sized thin-wall hydraulic spindle part were analyzed , focusing on its clamping mode , clamping deformation model analysis and processing flow .Then the processing scheme was proposed .In this scheme , central blocks on both ends and one clamping chuck and two core clampers method were used to process the spindle ;after the process-ing was completed , the spindle was repaired by using one clamping chuck and two support clamping method .By using the scheme , the processing of the spindle is successfully completed and the accuracy requirements are guaranteed .It provides reference for processing similar large-sized thin-wall spindle parts .%通过分析超大型薄壁类水电主轴件的主要加工难点,对工件装夹方式、 装夹变形模型分析、 加工工艺流程等进行详细研究,提出薄壁水电主轴件的加工方案.该方案采用两端配中心堵、 一夹两顶的装夹方式对工件进行车序加工,加工完毕后再使用一夹两托方式装夹工件进行修复,成功完成水电主轴工件的加工,满足产品精度要求,为同类超大型薄壁主轴零件加工提供了参考.
