The invention provides an integrated vertical 3D multifunctional numerical control carving machine, wherein the integrated vertical 3D multifunctional numerical control carving machine integrates the functions of cylinder surface carving, 3D carving, planar carving and the like, and is high in carving precision and working efficiency. A left stand column and a right stand column are connected to a machine tool body through a left guide rail and a right guide rail respectively. A Y-direction drive device is also arranged among the left stand column, the right stand column and the machine tool body. A gantry is arranged above the left stand column and the right stand column. A plurality of U-shaped shaft clamping devices and a chuck drive device for driving the U-shaped shaft clamping devices to rotate are arranged at the position, below the gantry, of the machine tool body. The gantry is movably provided with a movable base through an X-direction vertical guide rail and an X-direction horizontal guide rail. A carving head fixing board is movably arranged on the movable base through a left base guide rail and a right base guide rail. A Z-direction drive device is arranged between the movable base and the carving head fixing board. The carving head fixing board is provided with a plurality of carving heads matched with a tailstock. The integrated vertical 3D multifunctional numerical control carving machine further comprises an X-direction drive device connected with the movable base.
