[0002] A CNC engraving machine is a device that uses CNC technology to achieve precise engraving, and can perform high-precision processing on various materials according to a preset program; CNC engraving machines are mainly used for relief carving, flat carving, and hollow carving on materials such as wood, stone, advertising, glass, and metal (such as copper and aluminum). They also support the processing of various materials such as aluminum alloy, bakelite, jade, and plastic. The prior art CN202221736035.8 discloses a carving head moving adjustment device for a carving machine, including a base, a top seat above the base, an mounting plate slidably connected to the inner wall of the top seat, a connecting plate fixed to the bottom of the mounting plate, a first screw rotatably connected to the side wall of the connecting plate, a stepper motor that can drive the first screw to rotate on one side of the first screw, a transverse block threadedly connected to the outer side of the first screw, a rotating roller fixed to the side wall of the transverse block, a connecting block rotatably connected to the outer side of the rotating roller, a carving head installed at the bottom of the connecting block, a first connecting groove through the connecting block, a second connecting groove adapted to the first connecting groove when the carving head is vertically set, a third connecting groove adapted to the first connecting groove when the carving head is horizontally set, and a limiting block that can be inserted into the first connecting groove. However, in the use of existing technology, the head of the engraving machine can only move horizontally and vertically, that is, it can only complete the two-axis movement of the engraving machine and cannot drive the head to perform three-axis movement. In actual use, it cannot meet the needs of engraving more parts, reduces the processing flexibility of the head, has certain limitations, and has poor overall practicality. Therefore, this utility model proposes a head structure for a three-axis engraving machine to solve the above-mentioned problems of the existing technology. Utility Model Content

[0017] Please see Figure 1-4 The present invention provides an embodiment of a head structure for an engraving machine, including an X-axis slide plate 1, an X-axis motor 2 is provided on one side of the front end of the X-axis slide plate 1, the output shaft of the X-axis motor 2 is fixedly connected to an X-axis lead screw 3 through a coupling, an X-axis screw block 4 is threadedly connected to the X-axis lead screw 3, and the X-axis screw block 4 is fixedly connected to the X-axis slide plate 1. With this structural design, when the X-axis motor 2 is working, it can drive the X-axis lead screw 3 to rotate clockwise or counterclockwise through the output shaft and coupling. When the X-axis lead screw 3 rotates clockwise or counterclockwise, the X-axis screw block 4 connected to it can move along the X-axis lead screw 3. In this way, the movement of the X-axis screw block 3 can synchronously drive the X-axis slide plate 1 to move left and right, thereby achieving the effect of free movement of the machine head in the X-axis.

[0018] In order to improve the movement guidance of the X-axis slide plate 1 and maintain its linear displacement effect, several X-axis sliders 5 are fixedly installed on both sides of the lower surface of the X-axis slide plate 1. X-axis guide rails 6 are slidably connected to the X-axis sliders 5 on both sides. The X-axis guide rails 6 can be installed on the machine base of the engraving machine. Through the structural cooperation of the X-axis guide rails 6 and the X-axis sliders 5, a certain limiting sliding guidance effect can be provided for the left and right displacement of the X-axis slide plate 1, so that it can maintain the linear displacement effect and improve the displacement accuracy.

[0019] In this embodiment, in order to ensure the Y-axis movement effect of the machine head, a Y-axis slide plate 7 is provided above the X-axis slide plate 1, a Y-axis motor 8 is provided on one side of the Y-axis slide plate 7, the Y-axis motor 8 is fixedly installed on the X-axis slide plate 1, the output shaft of the Y-axis motor is connected to a Y-axis lead screw 9 through a coupling, a Y-axis screw block 10 is threaded on the outer surface of the Y-axis lead screw 9, and the Y-axis screw block 10 is fixedly connected to the Y-axis slide plate 7; This structure is the same as the X-axis drive principle described above. When the Y-axis motor 8 rotates clockwise or counterclockwise, it can synchronously drive the Y-axis lead screw 9 to rotate. When the Y-axis lead screw 9 rotates clockwise or counterclockwise, the Y-axis screw block 10 connected to it can move along the Y-axis lead screw 9. Thus, the movement of the Y-axis lead screw 9 can synchronously drive the Y-axis slide plate 7 to move back and forth, thereby achieving the effect of free movement of the machine head in the Y-axis direction. In order to ensure the guiding displacement of the Y-axis slide plate 7, Y-axis sliders 11 are fixedly installed on both sides of the lower surface of the Y-axis slide plate 7. Y-axis guide rails 12 are slidably connected inside the Y-axis sliders 11 on both sides. The Y-axis guide rails 12 are fixedly installed on the X-axis slide plate 1.

[0020] In this embodiment, in order to ensure the vertical lifting of the Z-axis of the machine head, a Z-axis motor 13 is fixedly installed on the Y-axis slide plate 7. The output shaft of the Z-axis motor 13 is connected to a Z-axis lead screw 19 through a coupling. A Z-axis screw block 14 is threaded onto the Z-axis lead screw 19. A Z-axis slide plate 15 is fixedly installed on one side of the outer wall of the Z-axis screw block 14. Z-axis guide rails 16 are fixedly installed on both sides of the back of the Z-axis slide plate 15. Z-axis slider 17 is slidably connected to the upper limit of the Z-axis guide rail 16. Z-axis slider 17 is fixedly installed on the Y-axis slide plate 7. In this structural design, the Z-axis motor 13 can rotate clockwise or counterclockwise. When the Z-axis motor 13 rotates clockwise or counterclockwise, it can synchronously drive the Z-axis lead screw 19 to rotate. When the Z-axis lead screw 19 rotates clockwise or counterclockwise, the Z-axis screw block 14 connected to it can move up and down along the Z-axis lead screw. In this way, the movement of the Z-axis screw block 14 can synchronously drive the Z-axis slide plate 15 to move up and down, thereby providing displacement conditions for the machine head to move up and down in the Z-axis direction.

[0021] In this embodiment, in order to ensure the normal processing of the engraving machine, a processing head 18 is fixedly installed on the outer wall of the front side of the Z-axis slide plate 15. The engraving tool can be installed through the processing head 18 to ensure normal CNC processing effect.

[0022] Working principle: When the machine head structure of this utility model is in use, the machine head assembly can be installed on a suitable engraving machine, thereby ensuring the normal use of the machine head. The processing machine head 18 set by this utility model can ensure the normal processing effect. This utility model is equipped with an X-axis motor 2. When the X-axis motor 2 is working, it can drive the X-axis lead screw 3 to rotate clockwise or counterclockwise through the output shaft and coupling. When the X-axis lead screw 3 rotates clockwise or counterclockwise, the X-axis screw block 4 connected to it can move along the X-axis lead screw 3. In this way, the movement of the X-axis screw block 3 can synchronously drive the X-axis slide plate 1 to move left and right, thereby achieving the effect of free movement of the machine head in the X-axis. Meanwhile, when the Y-axis motor 8 rotates clockwise or counterclockwise, it can synchronously drive the Y-axis lead screw 9 to rotate. When the Y-axis lead screw 9 rotates clockwise or counterclockwise, the Y-axis screw block 10 connected to it can move along the Y-axis lead screw 9. Thus, the movement of the Y-axis lead screw 9 can synchronously drive the Y-axis slide plate 7 to move back and forth, thereby achieving the effect of free movement of the machine head in the Y-axis direction. The Z-axis motor 13 can rotate clockwise or counterclockwise. When the Z-axis motor 13 rotates in both directions, it can synchronously drive the Z-axis lead screw 19 to rotate. When the Z-axis lead screw 19 rotates in both directions, the Z-axis screw block 14 connected to it can move up and down along the Z-axis lead screw. The movement of the Z-axis screw block 14 can synchronously drive the Z-axis slide plate 15 to move up and down, thus providing displacement conditions for the machine head to move up and down in the Z-axis direction.

[0023] In summary, the machining head 18 of this utility model can move along the X, Y, and Z axes respectively under the driving action of the aforementioned X-axis, Y-axis, and Z-axis drive structures. This gives the engraving machine head of this utility model a multi-axis movement effect with three-axis movement, enabling it to complete three-axis movement. Furthermore, the three-axis drive structures of the machining head 18 are independent of each other. Therefore, in actual use, its single-axis operation can drive the machining head 1 to perform single-axis movement, or it can perform coordinated linkage of two or three axes. (Three-axis linkage requires three sets of drive motors connected to the CNC control system of the engraving machine to achieve three-axis coordinated operation. This is a mature and publicly available technical solution in the field of CNC technology, and will not be elaborated further in this specification.) Thus, it achieves the three-axis linkage effect of the machine head. Because the three-axis drive structures are independent of each other, single-axis movement or multi-axis linkage can be performed according to the actual processing conditions. In actual processing, this effectively improves the processing flexibility of the machine head, has better three-axis linkage characteristics, and is more practical overall. It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
