Novel facing head mechanism

The utility model discloses a novel facing head mechanism. The novel facing head mechanism comprises a supporting frame, a main shaft, a rotary body, a slide carriage, a ball screw pair, a transmission shaft, a tool apron, a first power device and a second power device. The main shaft is fixedly installed on the supporting frame through a bearing. The left end of the main shaft is fixedly connected with the rotary body. The main shaft is in transmission connection with the first power device. The slide carriage is connected to the left end face of the rotary body through a rectangular guide rail in a slidable mode. The tool apron is fixedly installed on the slide carriage. The two ends of a lead screw of the ball screw pair are fixedly installed on the slide carriage. The transmission shaft is fixedly installed on the rotary body through a bearing, installed on the lead screw of the ball screw pair in a rotatable and sleeving mode, and fixedly connected with a nut of the ball screw pair. The lead screw is perpendicular to the main shaft. The second power device is in transmission connection with the transmission shaft. The novel facing head mechanism can realize radial feeding when the main shaft rotates, and the machining efficiency and machining quality of parts are improved.
