介绍了装载机驱动桥主减速器壳体组件车削工艺的改进和工装设计方法。依据具体的加工能力,选择合适的工艺方案,对现有的普通卧式车床进行简单改造,配置专用的工装夹具,扩大了其加工能力。工装夹具投入使用后,满足使用要求,可以高效、高质量地完成工件的加工。 The improvement of the turning process and the tooling design method for the main reducer housing assembly of the drive axle are introduced. According to the specific processing capacity, select the appropriate process options, the existing horizontal lathe simple transformation, configuration of special fixture, expanding its processing capacity. After the fixture is put into use, to meet the requirements, the workpiece can be processed efficiently and with high quality.
