Turning tool feeding structure of underfloor wheel lathe

The utility model relates to the technical field of mechanical cutting, and discloses a turning tool feeding structure of an underfloor wheel lathe, which comprises a mounting seat, a servo motor fixedly connected to the mounting seat, a ball screw rotationally connected to the mounting seat, a tool apron fixedly connected with a nut of the ball screw, and a tool fixedly connected to the tool apron, an output shaft of the servo motor and a lead screw of the ball screw are coaxially and fixedly connected with synchronous wheels, the two synchronous wheels are in transmission connection through a synchronous belt, and the device further comprises a limiting piece used for conducting circumferential limiting on a nut on the ball screw. According to the turning tool feeding structure, the requirements for the servo motor and the ball screw are reduced when the turning tool feeding structure is produced, and then the difficulty of producing the turning tool feeding structure is reduced. 本申请涉及机械切削的技术领域公开了一种不落轮车床的车刀
