偏心长轴的加工,一般是装夹在两顶针之间进行车削,加工时必须在工件两个端面上,根据偏心距e的要求,分别钻出四个中心孔,然后顶住中心孔进行车削。为了提高工效和质量,我们自制了图示加工偏心长轴的夹具,收到了较好的经济效果。夹具使用前,首先按图纸要求加工偏心外圆,用顶中心孔的方法加工,然后,把夹具安装在车床主轴上,调整中心架,将己 Eccentric long axis machining is usually carried between the two pins for turning, machining must be on both ends of the workpiece, according to the requirements of eccentricity e were drilled four center holes, and then withstand the center hole for turning . In order to improve ergonomics and quality, we made a self-made tooling eccentric long axis fixture, received a good economic results. Fixture before use, first according to the requirements of the drawings processing eccentric cylindrical, top center hole method of processing, and then, the fixture installed in the lathe spindle, adjust the center frame, will have
