Detailed implementation mode

[0028] The present invention will be further described below with reference to the accompanying drawings.

[0029] As Figure 1 shown, the present invention is a 3D dual-mode printing integrated device, including a mud pushing mechanism, a mud extrusion mechanism, a finishing mechanism and a five-axis linkage mechanism; the mud pushing mechanism is located at the top of the device and is connected to the mud extrusion mechanism. Both the mud extrusion mechanism and the finishing mechanism can move freely in the Y-axis direction, and the five-axis linkage mechanism realizes precise movement in the X-axis, Z-axis and polar coordinate directions.

[0030] As Figure 2 and Figure 3As shown in the figure, the mud pushing mechanism includes a first stepping motor 1a, a coupling 2, a smooth shaft bracket 3, a smooth shaft slider 4, a push rod reinforcement layer 5, a smooth shaft 6, a syringe fixing part 7, a wide-mouth dispensing syringe 8, a mud conveying hose 9, a rubber piston 10, a push rod 11, a first flange nut 28a, and a first lead screw 37a. Four smooth shafts 6 are arranged between two smooth shaft brackets 3, and a smooth shaft slider 4 is arranged on the smooth shaft 6, and the smooth shaft slider 4 can slide on the smooth shaft 6. The output end of the first stepping motor 1a passes through the center of one of the smooth shaft brackets 3 and is connected to the first lead screw 37a through the coupling 2. A syringe fixing part 7 is connected to the other smooth shaft bracket 3. One end of the wide-mouth dispensing syringe 8 is connected to the syringe fixing part 7, and the other end of the wide-mouth dispensing syringe 8 is connected to the mud conveying hose 9. The first flange nut 28a is fixed on the smooth shaft bracket 3, and a rotational movement is formed between the first lead screw 37a and the first flange nut 28a. The end of the first lead screw 37a is connected to the push rod 11. A push rod reinforcement layer 5 is arranged outside the push rod 11. The first stepping motor 1a, the coupling 2, the first flange nut 28a, the lead screw 37a, the smooth shaft slider 4, and the smooth shaft 6 cooperate to make the push rod 11 perform a reciprocating movement inside the wide-mouth dispensing syringe 8. A rubber piston 10 is installed at the head of the push rod 11, and the rubber piston 10 pushes the mud in the wide-mouth dispensing syringe 8, so that the mud is compressed. Then, the mud is stably extruded by the mud conveying hose 9 to the mud extrusion mechanism, and the mud is pushed into the mud extrusion mechanism. The mud pushing mechanism uses the syringe fixing part 7 to fix the wide-mouth dispensing syringe 8, preventing the uneven amount of mud pushed out by the wide-mouth dispensing syringe 8 caused by the vibration generated when the first stepping motor 1a drives the push rod 11 to move, and reducing the printing quality.

[0031] As Figure 4 and Figure 5As shown in the figure, the mud extrusion mechanism includes a second stepping motor 1b, a third stepping motor 1c, a first synchronous pulley 12a, an X-axis guide rail bracket 13, a limit switch bracket 14, a mud extrusion machine bracket 15, a self-tapping screw coupling 16, a quick-connect fitting air pipe nut 17, a mud delivery pipe connector 18, a mud extrusion head 19, a universal ball 20, a POM large wheel 21, a first synchronous belt 22a, a self-tapping screw 23, a third synchronous pulley 40a, a first limit switch 43a, a second limit switch 43b, and an X-axis guide rail 45a. The mud delivery pipe 9 is connected to the mud extrusion mechanism. The mud delivery pipe 9 is connected to the mud delivery pipe connector 18 through the quick-connect fitting air pipe nut 17. The mud delivery pipe connector 18 is connected to the mud extrusion head 19, forming a chamber for accommodating and conveying the mud. Inside the mud extrusion head 19, there is a self-tapping screw 23. The self-tapping screw 23 is connected to the third stepping motor 1c through the self-tapping screw coupling 16. The third stepping motor 1c is connected to the mud extrusion machine bracket 15 through four copper columns. The third stepping motor 1c drives the self-tapping screw coupling 16 to rotate, and the self-tapping screw coupling 16 drives the self-tapping screw 23 to rotate. Driven by this process, the mud is extruded along the thread of the self-tapping screw 23 to the mud extrusion head 19, realizing the extrusion of the mud.

[0032] The mud extrusion machine bracket 15 can slide on the X-axis guide rail 45a. The X-axis guide rail 45a is arranged on the X-axis guide rail bracket 13. The mud extrusion machine bracket 15 is driven to move by the second stepping motor 1b through the first synchronous pulley 12a, the third synchronous pulley 40a, and the first synchronous belt 22a. On one side of the X-axis guide rail 45a close to the X-axis guide rail bracket 13, there is a first limit switch 43a. The first limit switch 43a is installed on the limit switch bracket 14 and is used to limit the sliding range of the mud extrusion machine bracket 15. One end of the X-axis guide rail bracket 13 is movably connected to the longitudinal aluminum profile 36b of the present utility model through the universal ball 20, and the other end moves up and down on the longitudinal aluminum profile 36b through the three POM large wheels 21 of the X-axis guide rail bracket 13. The second limit switch 43b is arranged on the X-axis guide rail bracket 13 and is used to limit the moving position of the X-axis guide rail bracket 13 on the longitudinal aluminum profile 36b.

[0033] As Figure 6 and Figure 8As shown in the figure, the finishing mechanism is arranged parallel to the mud extrusion mechanism on the structural aluminum profile of the present utility model, and its structure is similar to that of the mud extrusion mechanism. It includes the fourth stepping motor 1d, POM large wheel 21, second synchronous belt 22b, horizontal aluminum profile bracket 24, brushless motor 25, brushless motor bracket 26, synchronous wheel bracket 27, second flange nut 28b, grinding bit 29 and horizontal aluminum profile 36a. The output end of the brushless motor 25 is connected to the grinding bit 29. The brushless motor 25 is installed on the brushless motor bracket 26, and the brushless motor bracket 26 can slide on the horizontal aluminum profile 36a driven by the fourth stepping motor 1d, synchronous wheels and the second synchronous belt 22b. Both ends of the horizontal aluminum profile 36a are arranged on the horizontal aluminum profile bracket 24. The structure of the horizontal aluminum profile bracket 24 is the same as that of the X-axis guide rail bracket 13, and three POM large wheels 21 are also provided for moving up and down on the longitudinal aluminum profile 36b in the present utility model. Similar to the mud extrusion mechanism, the synchronous wheels in the finishing mechanism are fixed by the synchronous wheel bracket 27 arranged on the horizontal aluminum profile bracket 24. In addition, second flange nuts 28b are provided on both the horizontal aluminum profile bracket 24 and the X-axis guide rail bracket 13, and are respectively driven by two second lead screws 37b to move up and down on the longitudinal aluminum profile 36b. The second lead screw 37b is connected to the fifth stepping motor 1e through the second lead screw coupling 38b. In the mud extrusion mechanism, the up and down movement of the X-axis guide rail bracket 13 on the Z-axis is realized by Figure 9 the ninth stepping motor 1i in

[0034] As Figures 7 to 9 shown in the figure, the five-axis linkage mechanism is arranged directly below the mud extrusion mechanism, and includes the sixth stepping motor 1f, seventh stepping motor 1g, eighth stepping motor 1h, ninth stepping motor 1i, second synchronous wheel 12b, third synchronous belt 22c, fourth synchronous belt 22d, fifth synchronous wheel 30, mud printing turntable 31, inner bracket 32 of the mud printing turntable, outer bracket 33 of the mud printing turntable, bearing base turntable 34, stepping motor bracket 35, bottom aluminum profile 36c, mud printing turntable base 39, fourth synchronous wheel 40b, base leveling hand-tightening nut 41, printer base 42, third limit switch 43c, printing turntable base leveling spring 44 and Y-axis guide rail 45b.

[0035] The seventh stepping motor 1g is set on the stepping motor bracket 35, and the stepping motor bracket 35 is installed on the side of the outer bracket 33 of the mud printing turntable. The seventh stepping motor 1g drives the fifth synchronous pulley 30 to rotate through the third synchronous belt 22c, and the fifth synchronous pulley 30 drives the inner bracket 32 of the mud printing turntable inside the outer bracket 33 of the mud printing turntable to rotate. A sixth stepping motor 1f, a bearing base turntable 34 and a mud printing turntable 31 are installed on the inner bracket 32 of the mud printing turntable. The mud printing turntable 31 is installed on the bearing base turntable 34 and is driven by the sixth stepping motor 1f to rotate. The 3D printed product realizes multi-directional movement under the movement of the mud printing turntable 31 and is controlled by a precision control system to ensure that the 3D printed product can be finely repaired at multiple angles and in multiple directions after printing. The fine repair operation cooperates with the grinding bit 29 controlled by the fine repair mechanism to adjust the spatial position of the grinding bit 29. Through the five-axis linkage mechanism, the grinding bit 29 is in close contact with the surface of the 3D printed product, and the grinding bit 29 cuts and wears the surface of the 3D printed product during high-speed rotation. Through continuous cutting and wearing actions, the surface of the product is further smoothed and flattened, significantly improving the manufacturing precision and quality of the final product. The fine repair process not only optimizes the appearance of the product but also enhances its functionality, fully demonstrating the technical advantages of the present utility model in the field of precision manufacturing.

[0036] The outer bracket 33 of the mud printing turntable is fixed on the base 39 of the mud printing turntable. The base 39 of the mud printing turntable is a double-layer structure. Between the two layers of the base 39 of the mud printing turntable at its four corners, there are printing turntable base leveling springs 44, and the balance of the base 39 of the mud printing turntable can be manually fine-tuned through the base leveling hand-tightening nut 41. The base 39 of the mud printing turntable can slide on the Y-axis guide rail 45b and is driven by the eighth stepping motor 1h to drive the second synchronous pulley 12b, the fourth synchronous pulley 40b and the fourth synchronous belt 22d. Similarly, a third limit switch 43c is also provided on the Y-axis guide rail 45b to limit the sliding position of the base 39 of the mud printing turntable. The Y-axis guide rail 45b, the eighth stepping motor 1h and the ninth stepping motor 1i are all set on the bottom aluminum profile 36c, and its bottom is supported by the printer base 42.

[0037] The five degrees of freedom of the five-axis linkage mechanism are provided by Figure 7 the sixth stepping motor 1f and the seventh stepping motor 1g used to control the polar coordinates in Figure 8 the fourth stepping motor 1d used to control the X-axis and the fifth stepping motor 1e used to control the Z-axis in Figure 9It consists of the eighth stepper motor 1h that controls the Y-axis. The above five stepper motors are linked to achieve five-degree-of-freedom 3D printing. The second stepper motor 1b and the eighth stepper motor 1h, in cooperation with the mud pushing mechanism and the mud extrusion mechanism, form a single-layer printed pattern on the printing platform plane composed of the X-axis and the Y-axis through the natural curing of the mud. After completing a single-layer printing, the ninth stepper motor 1i controls the mud extrusion mechanism to lift by a height required for a single-layer printing on the Z-axis. At the same time, the mud in the mud pushing mechanism refills this space and repeats the above printing steps. Through multiple single-layer printings as described above, a 3D printed product is finally formed.
