Abstract: A quick-change mechanism and tool changing method for realizing variable diameter turning by machine tools. The quick-change mechanism enables a turning tool 10 of a CNC machine tool to move along a U-axis direction and rotate around the axis of a spindle. Therefore, a workpiece to be machined is subjected to variable diameter turning by active motion of the turning tool 10 without rotational motion of the workpiece, thus realizing machining of a conical surface. The tool changing method is implemented by the motion coordination among variable diameter turning tool head units, the power seat unit, the spindle mounting unit, a variable diameter turning tool head grasping mechanism, a variable diameter turning tool head unit storing bank and a power seat unit storing plate is realized.
