Then the operator removes the engraving embryo, and then puts the embryo to be engraved into the three-jaw chuck 71, and then controls the three-jaw chuck 71 to clamp the embryo. Since multiple groups of three-jaw chucks 71 are provided, multiple groups of engraving knives 63 can simultaneously engrave multiple groups of embryos, thereby improving the engraving efficiency. During the installation of the embryo, the electric lifting rod 42 is controlled to press the height of the pressing plate 5 down close to the top area of ​​the embryo, and then the operator rotates the rotating wheel 52, and the rotating wheel 52 rotates and drives the pressing rod 53 to rotate. The pressing rod 53 rotates and descends inside the sleeve 51, and the bottom of the pressing rod 53 drives the turntable 531 to rotate and descend continuously, and then rotates and presses the top of the embryo, thereby further ensuring the stability of the embryo during the engraving process.

[0043] A parts installation unit is arranged on the top of the engraving table 4 and is used for storing and installing the workpiece to be engraved.

As the reciprocating frame 2 moves vertically, the guide block 22 installed on the reciprocating frame 2 moves vertically on the guide rod 123 through the guide hole 23, thereby ensuring the stability of the reciprocating frame 2 during the vertical movement.

[0049] Embodiment 2:

[0050] Based on the first embodiment, in this embodiment, if the tool cannot rotate during the engraving process, but the embryo can rotate under the action of the electric turntable 7, the engraving angle of the engraving tool 63 will be limited, resulting in poor engraving efficiency of the embryo. Therefore, an engraving unit is provided in this embodiment, and the engraving unit can drive the engraving tool 63 to rotate synchronously with the embryo, thereby improving the engraving efficiency of the embryo;

[0051] An engraving unit is provided on one side of the reciprocating frame 2, and the engraving unit includes a mounting plate 6, which is mounted on one side of the reciprocating frame 2, on which a rotating shaft 64 is rotatably mounted, and an engraving frame 61 is mounted on an adjacent rotating shaft 64, and a motor frame 65 is mounted on one side of one mounting plate 6, in which a forward and reverse motor 66 is mounted, and the rotating end of the forward and reverse motor 66 is fixed to one end of a rotating shaft 64.

[0053] In this embodiment, when the engraving embryo has been engraved, the operator can drive the electric lifting rod 42 to lift the height of the pressing plate 5, and then release the three-jaw chuck 71. The operator then takes down the engraving embryo, and then puts the embryo to be engraved into the three-jaw chuck 71, and then controls the three-jaw chuck 71 to clamp the embryo. Since multiple groups of three-jaw chucks 71 are provided, multiple groups of engraving knives 63 can simultaneously engrave multiple groups of embryos, thereby improving the engraving efficiency. During the installation of the embryo, the electric lifting rod 42 is controlled to press the height of the pressing plate 5 down close to the top area of ​​the embryo. Then the operator rotates the rotating wheel 52, and the rotating wheel 52 rotates and drives the pressing rod 53 to rotate. The pressing rod 53 rotates and descends inside the sleeve 51, and the bottom of the pressing rod 53 drives the turntable 531 to rotate and descend continuously, and then rotates and presses the top of the embryo, thereby further ensuring the stability of the embryo during the engraving process.

[0055] An X-axis guide rail 3 and a Y-axis guide rail 15 are placed above the base. The X-axis guide rail 3 moves left and right. The X-axis guide rail 3 can move left and right. With the movement of the X-axis guide rail 3, the engraving table 4 can be driven to move left and right. The Z-axis guide rail 121 can drive the reciprocating frame 2 to move vertically up and down, thereby adjusting the vertical distance of the engraving knife 63.

The forward and reverse motor 66 drives the rotating shaft 64 to rotate, and then the rotating shaft 64 drives the engraving frame 61 and the engraving knife 63 to rotate and engrave. The electric turntable 7 drives the three-claw chuck 71 to rotate the embryo, thereby forming a five-axis synchronous motion to improve the stability during processing. When the engraved embryo has been engraved, the operator can drive the electric lifting rod 42, thereby lifting the pressure plate 5, and then releasing the three-jaw chuck 71. The operator then removes the engraving embryo, and then replaces the embryo to be engraved and puts it into the three-jaw chuck 71, and then controls the three-jaw chuck 71 to clamp the embryo. Since multiple sets of three-jaw chucks 71 are provided, multiple sets of engraving knives 63 can simultaneously engrave multiple sets of embryos, thereby improving the engraving efficiency. During the installation of the embryo, the electric lifting rod 42 is controlled to press the pressure plate 5 down to the top area of ​​the embryo, and then the operator rotates the rotating wheel 52, and the rotating wheel 52 rotates and drives the pressure rod 53 to rotate. The pressure rod 53 rotates and descends inside the sleeve 51, and the bottom of the pressure rod 53 drives the turntable 531 to continuously rotate and descend, and then rotates and presses the top of the embryo, thereby further ensuring the stability of the embryo during the engraving process.
