[0002] By installing a turning power head on the CNC lathe and controlling the speed ratio between the spindle and the turning power head through the system, turning processing can be achieved.

[0003] CN 209050174 U A turning and milling compound power head comprises a power head housing, a driving motor and a cutter disc shaft. The driving motor is fixed to the rear end of the power head housing. The cutter disc shaft is rotatably arranged in the power head housing, one end of which is connected to the output shaft of the driving motor and the other end extends out of the power head housing and is equipped with a flying cutter disc.

[0004] The turning power head of the CN 209050174 U technical solution is directly connected to the motor for transmission. The output torque of the turning power head is equal to the motor torque. The torque is small and the vibration resistance is poor, which leads to serious vibration marks on the part processing surface and short tool life, seriously affecting the turning performance of the lathe, and failing to achieve the advantage of high turning efficiency.

[0010] The number of teeth of the cutter shaft synchronous wheel is preferably greater than that of the motor shaft synchronous wheel, thereby achieving a reduction transmission and increasing the cutting torque of the cutter. A counterweight balance wheel is provided at one end of the cutter shaft of the power head to stabilize and balance the inertia and impact force of intermittent cutting, making the cutting more powerful and reducing vibration.

[0011] Preferably, the circumferential surface of the counterweight balance wheel is provided with 4 or more equiangularly distributed wrench sockets, and the dynamic balance of the counterweight balance wheel is adjusted by the depth of the wrench sockets. In addition, the wrench is inserted into the wrench socket to facilitate manual rotation of the cutter head.

[0012] The beneficial effect of the utility model is that the direct-connected motor is replaced by a synchronous belt, which increases the torque output of the motor, improves the cutting force, reduces intermittent cutting vibration, and thus improves the processing surface quality and tool life; the turning power can be used as a standardized module accessory for metal cutting machine tools, and can be used for lathe technical transformation or CNC lathe to increase the turning function.
