The invention relates to a shaft gear composite
processing machine tool which comprise a tool body, a column, a rotary working platform, a hob feeding mechanism, a supporting frame feeding mechanism and a rotary knife
tower feeding mechanism, wherein the column, the rotary working platform, the hob feeding mechanism, the supporting frame feeding mechanism and the rotary knife
tower feeding mechanism are fixed on the tool body. The rotary working platform is fixed on the top surface of the tool body, and the hob feeding mechanism, the supporting frame feeding mechanism and the rotary knife
tower feeding mechanism are horizontally and sequentially arranged on one side of the column close to the rotary working platform and matched with the column in the vertical direction in sliding mode. A workpiece is clamped once, turning,
hobbing, milling, chamfering, burring, drilling and the like are performed on gears of different sizes through rotation of the working platform, switch of different
processing knives, horizontal and longitudinal feeding and rotation of angles.
Switching time of the workpiece between different
machine tools is saved,
processing efficiency is improved, and processing precision of parts is guaranteed to the maximum limit.
