Automatic lathe for machining cylindrical workpiece

The invention relates to an automatic lathe for machining a cylindrical workpiece. The technical problems that in the prior art, when a cylindrical workpiece machining lathe carries out machining work, no automatic feeding function is achieved, the large batch machining work efficiency is low, direct driving of an oil cylinder is adopted during spindle part feeding in the prior art, rigidity for workpiece locating is poor, vibration is likely to happen during machining, and the machining precision is influenced are mainly solved. According to the automatic lathe, the technical scheme of additionally arranging an automatic feeding mechanism and a locating core shaft is adopted, the problems are solved well, and the automatic lathe can be used for industrial production of the utomatic lathefor machining the cylindrical workpiece. 本发明涉及种用于圆柱形工件加工的自动车床，主要解决现有技术中存在的圆柱形工件加工车床在加工作业时，不具备自动上料功能，对于大批量的加工作业而言显得效率低下，且现有技术中主轴部分进给采用油缸直接驱动，对于定位工件的刚性不好，加工时易振动，影响加工精度的技术问题，本发明通过采用增加自动上料机构和定位芯轴的技术方案，较好的解决了该问题，可用于圆柱形工件加工自动车床的工业生
