Boring head for deep hole boring machine

The invention discloses a boring head for a deep hole boring machine, and belongs to the field of machining. The boring head comprises an installing sleeve, an installing shaft and an installing base.The installing base comprises a middle disc and two installing arms which are fixedly connected to the periphery wall of the middle disc. The two installing arms are perpendicular to the center axisof the middle disc, are parallel and are symmetrically arranged relative to the center axis of the middle disc. The installing sleeve and the installing shaft are fixedly connected to the side wall ofthe middle disc and located on the two reverse sides of the middle disc correspondingly, an installing hole is coaxially formed in the installing sleeve, and the installing hole and the installing shaft are coaxially arranged. By means of the boring head, high-precision boring of deep holes with the large hole diameter can be achieved. 本发明公开了种用于深孔镗床的镗头，属于机械加工领域。该镗头包括安装套、安装轴和安装座，安装座包括中间盘和两个安装臂，两个安装臂均固定连接在中间盘的外周壁上，两个安装臂均垂直于中
