Abstract

The invention discloses a cylindrical engraving machine, which solves the technical problem that engraving heads of an existing engraving machine have unclear location and low engraving precision, and the like. An X-directional driving device is arranged between a plurality of engraving heads and portal cranes, a Y-directional driving device with two synchronous sides is arranged between a left upright column, a right upright column and a bed body, the engraving heads realize a Z-directional motion; a work-piece is driven by a U-shaft driving device to automatically rotate, a control system controls the engraving heads to locate in the X direction, the Y direction and the Z direction; an engraving motor automatically rotates to implement an engraving operation. As the X direction adopts a gear rack transmission mode, and the location is precise, the Y direction adopts a two-side synchronous driving mode, so the location precision is further improved. A plurality of three-jaw chucks are synchronously rotated, work-pieces are fixed on the three-jaw chucks, the circumferential location of the work-pieces are accurate, two ends of the work-pieces are respectively fixed by a top core and a centre of the chucks, and thus the work-pieces cannot generate a displacement deviation in an axial direction; during processing, the work-pieces are firmly fixed, so a higher load can be supported by the work-pieces.
