[0002] Jade carving is a traditional and meticulous craft, widely used in ornaments, handicrafts, jewelry, and works of art. With technological advancements, modern jade carving machines have gradually incorporated CNC technology and automated control, greatly improving carving precision and production efficiency.

[0003] In existing technologies, the carving needles of some jade carving machines can only move along the X, Y, and Z axes in three axes, and the carving needles do not have additional rotation functions in the vertical direction. When facing complex carving needs, the limited rotation of the carving needles may result in insufficient precision in the carving process, especially when carving high-precision jade with complex curved surfaces, which is easily constrained by factors such as processing space and angle. Therefore, a dual-spindle four-axis linkage jade carving machine is designed to change the above-mentioned technical defects. Summary of the Invention

[0024] This specific embodiment is a dual-spindle four-axis linkage jade carving machine, and its structural schematic diagram is as follows: Figures 1-6 As shown, the engraving machine includes a U-shaped moving frame 1, with rectangular mounting bases 2 at both ends of the bottom of the U-shaped moving frame 1, and vertical lifting blocks 4 that can be raised and lowered at both ends of the U-shaped moving frame 1. A rotatable rectangular mounting block 5 is provided on one side of the vertical lifting block 4, and a longitudinal rotating box 6 is rotatably connected inside the rectangular mounting block 5. A longitudinal engraving needle 7 is provided on one side of the longitudinal rotating box 6, and a rotating mechanism for rotating the longitudinal rotating box 6 is provided between the vertical lifting block 4 and the rectangular mounting block 5.

[0025] A transverse hydraulic cylinder 3 is fixed inside the rectangular mounting base 2. The output end of the transverse hydraulic cylinder 3 is fixedly connected to the U-shaped movable frame 1, and the U-shaped movable frame 1 is slidably connected to the rectangular mounting base 2.

[0026] Here, the operation of the transverse hydraulic cylinder 3 enables the U-shaped moving frame 1 to slide laterally inside the rectangular mounting base 2, thereby enabling the longitudinal engraving needle 7 to move laterally.

[0027] A rectangular mounting plate 8 is fixed to the top of the U-shaped moving frame 1 on the side away from the rectangular mounting block 5. A first drive motor 9 is fixed to the output end of the rectangular mounting plate 8. A vertical threaded rod 10 is fixed to the output end of the first drive motor 9. The vertical threaded rod 10 passes through the interior of the vertical lifting block 4 and is threadedly connected to the vertical lifting block 4.

[0028] T-shaped sliders are fixed at both ends of the U-shaped moving frame 1. The vertical lifting block 4 has a T-shaped groove inside that matches the T-shaped slider. The U-shaped moving frame 1 and the vertical lifting block 4 are slidably connected by the T-shaped slider and the T-shaped groove. The T-shaped slider and the T-shaped groove allow the vertical lifting block 4 to slide vertically on the outside of the U-shaped moving frame 1, thereby allowing the longitudinal engraving needle 7 to move vertically.

[0029] Here, the operation of the first drive motor 9 enables the vertical threaded rod 10 to rotate. The rotation of the vertical threaded rod 10 enables the vertical lifting block 4 to slide vertically on the outside of the U-shaped moving frame 1, thereby enabling the vertical engraving needle 7 to rise and fall vertically, and enabling the position of the vertical engraving needle 7 to be vertically adjusted.

[0030] The rotating mechanism includes an L-shaped mounting plate 11. The top of the vertical lifting block 4 is fixed with an L-shaped mounting plate 11. A vertical hydraulic cylinder 12 is fixed inside the L-shaped mounting plate 11. The output end of the vertical hydraulic cylinder 12 is rotatably connected to an inclined rotating column 14. The bottom of the inclined rotating column 14 is rotatably connected to a longitudinal rotating plate 15. The end of the vertical lifting block 4 near the rectangular mounting block 5 is rotatably connected to a transverse rotating column 13 via a bearing. The transverse rotating column 13 is fixedly connected to the rectangular mounting block 5. The longitudinal rotating plate 15 is sleeved on the outside of the transverse rotating column 13 and fixedly connected to the transverse rotating column 13. One end of the longitudinal rotating plate 15 is rotatably connected to an inclined hydraulic cylinder 16. The output end of the longitudinal hydraulic cylinder 17 is rotatably connected to the longitudinal rotating box 6 via a pin.

[0031] Here, the operation of the vertical hydraulic cylinder 12, through the setting of the oblique rotating column 14, enables the longitudinal rotating plate 15 to drive the transverse rotating column 13 to rotate. The rotation of the transverse rotating column 13 causes the rectangular mounting block 5 to rotate, thereby enabling the longitudinal engraving needle 7 to rotate around the transverse rotating column 13. Through the operation of the oblique hydraulic cylinder 16, the longitudinal rotating box 6 can rotate around the connection between the longitudinal rotating box 6 and the rectangular mounting block 5, thereby enabling the longitudinal engraving needle 7 to rotate.

[0032] A longitudinal hydraulic cylinder 17 is fixed inside the longitudinal rotating box 6. A longitudinal sliding plate 18 is fixed to the output end of the longitudinal hydraulic cylinder 17. A second drive motor 19 is bolted to one end of the longitudinal sliding plate 18. The output end of the second drive motor 19 is fixedly connected to the longitudinal engraving needle 7.

[0033] The interior of the longitudinal rotating box 6 is provided with a longitudinal sliding groove. The longitudinal rotating box 6 and the longitudinal sliding plate 18 are slidably connected through the longitudinal sliding groove. The longitudinal sliding groove allows the longitudinal sliding plate 18 to slide longitudinally inside the longitudinal rotating box 6.

[0034] Here, the operation of the longitudinal hydraulic cylinder 17 enables the longitudinal sliding plate 18 to move inside the longitudinal rotating box 6, thereby enabling the longitudinal carving needle 7 to move longitudinally. The operation of the second drive motor 19 enables the longitudinal carving needle 7 to rotate, so that the longitudinal carving needle 7 can process the jade.

[0035] With free movement of three axes and rotation of two axes, the longitudinal engraving needle 7 can perform precise engraving at more complex angles, avoiding the engraving errors caused by the limited angle of traditional engraving machines. This greatly improves the detail and precision of the engraving and allows for more flexible angle adjustment, which is key to improving the precision and complexity of jade carving and enhancing the applicability of the engraving machine in different carving scenarios.

[0036] Working principle: When using the engraving machine of this technical solution, the operation of the transverse hydraulic cylinder 3 enables the U-shaped moving frame 1 to slide laterally inside the rectangular mounting base 2, thereby enabling the longitudinal engraving needle 7 to move laterally.

[0037] The operation of the first drive motor 9 enables the vertical threaded rod 10 to rotate. The rotation of the vertical threaded rod 10 enables the vertical lifting block 4 to slide vertically on the outside of the U-shaped moving frame 1, thereby enabling the vertical engraving needle 7 to rise and fall vertically, and the position of the vertical engraving needle 7 to be vertically adjusted.

[0038] The operation of the vertical hydraulic cylinder 12, through the setting of the inclined rotating column 14, enables the longitudinal rotating plate 15 to drive the transverse rotating column 13 to rotate. The rotation of the transverse rotating column 13 causes the rectangular mounting block 5 to rotate, thereby enabling the longitudinal engraving needle 7 to rotate around the transverse rotating column 13. Through the operation of the inclined hydraulic cylinder 16, the longitudinal rotating box 6 can rotate around the connection between the longitudinal rotating box 6 and the rectangular mounting block 5, thereby enabling the longitudinal engraving needle 7 to rotate.

[0039] The operation of the longitudinal hydraulic cylinder 17 enables the longitudinal sliding plate 18 to move inside the longitudinal rotating box 6, thereby enabling the longitudinal carving needle 7 to move longitudinally. The operation of the second drive motor 19 enables the longitudinal carving needle 7 to rotate, so that the longitudinal carving needle 7 can process the jade.

[0040] All technical features in this embodiment can be freely combined according to actual needs.

[0041] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
