Description

Technical Field

[0001] This utility model relates to the field of 3D printing equipment technology, specifically a gantry-type 3D printing equipment for manufacturing composite material components. Background Technology

[0002] In high-end manufacturing sectors such as aerospace, shipbuilding, and automotive, the increasing demands for high strength, lightweight, and complex molding of components have led to a continuous increase in the application of composite materials in component manufacturing, thanks to their superior mechanical properties, weight reduction effects, and design adaptability. However, traditional manufacturing methods for composite materials have significant limitations, making it difficult to meet the current industry's demands for efficient, high-precision, and low-cost production: manual lay-up methods rely on manual operation, resulting in low production efficiency and component quality that is greatly affected by the operator's skill, making consistency difficult to guarantee; compression molding requires customized molds, which are costly and only suitable for relatively simple components, unable to achieve integrated molding of complex and irregular structures; and filament winding is limited to axisymmetric components, with a narrow range of applications, making it difficult to meet the diverse component manufacturing needs.

[0003] Gantry 3D printing equipment has become an important technology direction for the manufacturing of large composite material components due to its advantages such as strong motion stability, large working space and high printing accuracy. However, in actual application, after the composite material component is 3D printed, the printed component needs to be removed from the printing table and transferred to a dedicated milling machine or other trimming device. Then, milling cutters and other tools are used to cut and trim the excess material on the surface of the component, the printed support structure, and the parts with dimensional deviations caused by the printing process in order to finally obtain a component that meets the design accuracy requirements. This process results in low production efficiency, high risk of secondary positioning error, and increased equipment investment and site costs.

[0004] In view of the above, this application is hereby submitted. Utility Model Content

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-7 This utility model provides a technical solution: a gantry 3D printing device for manufacturing composite material components, including a printing X-axis travel track 1, a gantry X-axis travel track 2 and a feeding assembly. A printing platform 38 is slidably installed on the printing X-axis travel track 1, a gantry truss 3 is slidably installed on the gantry X-axis travel track 2, the gantry truss 3 spans above the printing platform 38, a Y-axis slide rail 4 extending along its length direction is installed on the side wall of the gantry truss 3, a Y-axis rack 5 parallel to the Y-axis slide rail 4 is installed on the side wall of the gantry truss 3, and a printing assembly and a cutting assembly are also installed on the gantry truss 3;

[0027] The printing assembly includes a Y-axis first slide block 6 that is slidably mounted on a Y-axis slide rail 4, a Z-axis first slide column 7 that is slidably mounted on the Y-axis first slide block 6, a rotary connecting disk 28 that is mounted at the bottom end of the Z-axis first slide column 7, and a printing extrusion device 29 that is mounted on the rotary connecting disk 28.

[0028] The cutting assembly includes a second Y-axis slide block 31 slidably mounted on a Y-axis slide rail 4, a second Z-axis slide column 32 slidably mounted on the second Y-axis slide block 31, a universal end mill head 30 mounted at the bottom end of the second Z-axis slide column 32, a Y-axis motor 33 mounted on the second Y-axis slide block 31, and a Y-axis gear 35 that meshes with the Y-axis rack 5 mounted at the drive end of the Y-axis motor 33.

[0029] Specifically, this equipment uses X, Y, and Z axis motion as its core to construct an integrated printing and cutting operation system:

[0030] X-axis movement: The printing platform 38 slides along the two sets of printing X-axis travel tracks 1 in the X-axis direction to adjust the X-axis position of the printing substrate; the gantry truss 3 slides along the two sets of gantry X-axis travel tracks 2 in the X-axis direction, driving the printing component and the cutting component to complete the X-axis displacement synchronously, and the gantry truss 3 is straddling above the printing platform 38 to ensure that the operation covers the entire printing area.

[0031] Y-axis movement: The first Y-axis slide 6 of the printing component and the second Y-axis slide 31 of the cutting component are both slidably mounted on the Y-axis slide rail 4. The cutting component drives the Y-axis gear 35 to mesh with the Y-axis rack 5 through the Y-axis motor 33, so as to achieve precise Y-axis positioning of the second Y-axis slide 31. Similarly, the printing component can complete the Y-axis movement through the matching drive structure.

[0032] Z-axis and operation execution: The first slide column 7 of the Z-axis slides along the first slide block 6 of the Y-axis, and the rotating connecting disk 28 at its bottom end drives the printing extrusion device 29 to rotate, realizing multi-directional printing operation; the second slide column 32 of the Z-axis slides along the second slide block 31 of the Y-axis, driving the universal milling cutter head 30 to move up and down to complete the cutting and trimming operation.

[0033] As a technical optimization of this utility model, a Z-axis first motor 8 is installed on the Y-axis first slide block 6, a Z-axis first rack 9 extending along its length is installed on the side wall of the Z-axis first slide column 7, a Z-axis first gear 10 meshing with the Z-axis first rack 9 is installed on the drive end of the Z-axis first motor 8, a Z-axis second motor 34 is installed on the Y-axis second slide block 31, a Z-axis second rack 37 extending along its length is installed on the side wall of the Z-axis second slide column 32, and a Z-axis second gear 36 meshing with the Z-axis second rack 37 is installed on the drive end of the Z-axis second motor 34.

[0034] Specifically, the Z-axis drive of the printing component: the Z-axis first motor 8 is fixed to the Y-axis first slide block 6, and the Z-axis first gear 10 at its drive end meshes with the Z-axis first rack 9 on the side wall of the Z-axis first slide column 7. Through gear and rack transmission, the Z-axis first slide column 7 is driven to move linearly up and down along the Y-axis first slide block 6, so as to precisely adjust the Z-axis height of the printing extrusion device 29.

[0035] Z-axis drive of the cutting assembly: The second Z-axis motor 34 is fixed to the second Y-axis slide 31. The second Z-axis gear 36 at its drive end meshes with the second Z-axis rack 37 on the side wall of the second Z-axis slide column 32, thereby achieving precise Z-axis displacement of the universal end mill head 30.

[0036] As a technical optimization of this utility model, both the printing X-axis travel track 1 and the gantry X-axis travel track 2 are provided in two sets. The two sets of printing X-axis travel tracks 1 and gantry X-axis travel tracks 2 are arranged in parallel and symmetrically, and the two sets of printing X-axis travel tracks 1 are located between the two sets of gantry X-axis travel tracks 2.

[0037] Specifically, two sets of printing X-axis travel tracks 1 and gantry X-axis travel tracks 2 are provided, and they are arranged in a parallel and symmetrical manner. The two sets of printing X-axis travel tracks 1 are located between the two sets of gantry X-axis travel tracks 2.

[0038] Two sets of X-axis travel tracks 1 provide symmetrical support for the printing platform 38, ensuring that the printing platform 38 is subjected to uniform force when sliding along the X-axis, and avoiding tilting or shaking caused by single-sided track support.

[0039] Two sets of gantry X-axis traveling tracks 2 provide double-sided support for the gantry truss 3, improving the load-bearing capacity and movement stability of the gantry truss 3. In particular, when the gantry truss 3 drives the printing component, cutting component and feeding component to move as a whole, it can effectively distribute the load.

[0040] As a technical optimization of this utility model, the feeding assembly includes a material tank 11 installed on the gantry truss 3 for feeding printing materials to the printing extrusion device 29. A bracket 17 and a hopper 21 are installed at the end of the sliding path of the gantry truss 3. A cylinder 18 is installed at the top of the bracket 17. A feeding pipe 19 is installed at the telescopic end of the cylinder 18. One end of the feeding pipe 19 is connected to a feeding male head 20, and the other end extends into the hopper 21 and is connected to a first vacuum feeder 27. A feeding pipe 23 is installed on the material tank 11. The end of the feeding pipe 23 away from the material tank 11 is connected to a feeding female head 24 that cooperates with the feeding male head 20. The feeding female head 24 has a conical structure. The feeding male head 20 and the feeding female head 24 are adapted to each other. A plurality of sealing rings 25 are installed on the inner wall of the feeding female head 24 at intervals.

[0041] Specifically, the material tank 11 on the gantry truss 3 is equipped with a heating and dehumidification module, enabling the material tank 11 to store and dry materials. At the end of the path of the gantry truss 3, a support 17 and a hopper 21 are set. The cylinder 18 at the top of the support 17 pushes the feeding pipe 19, so that the feeding male head 20 of the feeding pipe 19 connects with the feeding female head 24 of the feeding pipe 23 of the material tank 11. The first vacuum feeder 27 transports the material in the hopper 21 to the material tank 11 through the feeding pipe 19. During operation, when the material in the material tank 11 is insufficient, the equipment automatically triggers the feeding process: the gantry truss 3 moves to the support 17, the cylinder 18 drives the feeding male head 20 to seal and connect with the feeding female head 24, the first vacuum feeder 27 starts to achieve negative pressure feeding, and the sealing ring 25 ensures that there is no material leakage at the connection point, thus completing the automatic replenishment.

[0042] As a technical optimization of this utility model, the material tank 11 is provided with a stirring shaft inside, which can rotate around its own axis. The top surface of the material tank 11 is equipped with a stirring motor 22 that drives the stirring shaft to rotate. The bottom surface of the material tank 11 is equipped with a material conveying tank path that connects to the printing extrusion device 29. A second vacuum feeder 26 is installed on the material conveying tank path.

[0043] Specifically, the stirring motor 22 drives the stirring shaft to rotate continuously, uniformly stirring the composite material in the material tank 11 to prevent the material from clumping due to static standing and to accelerate the drying efficiency of the material; during the printing stage, the second vacuum feeder 26 is started to stably transport the uniformly stirred material to the printing extrusion device 29 through the conveying tank path, ensuring that the density and flowability of the extruded material are consistent.

[0044] As a technical optimization of this utility model, it also includes an electrical cabinet 12, an operating table 13, a water chiller 14, a compressed air storage tank 15, and an air compressor 16, which are set on the bottom surface to assist 3D printing.

[0045] Specifically, during operation, the electrical cabinet 12 provides power control and signal transmission for the various motors of the equipment, including the Y-axis motor 7, Z-axis motor 31, stirring motor 22, the first vacuum feeder 27, the second vacuum feeder 26, and the actuators; the control panel 13 is used to set printing / trimming parameters, monitor the equipment's operating status, and perform manual operation; the water chiller 14 provides cooling for the high-temperature melting of materials in the printing extrusion device 29 and the material tank 11 to prevent the materials from deteriorating at high temperatures; the air compressor 16 generates compressed air, which is stored in the compressed air storage tank 15, providing power for the driving of the cylinder 18 and the cleaning of waste materials during the trimming of the universal milling head 30.

[0046] In this gantry-type 3D printing equipment used for manufacturing composite material components, the core structures form a cohesive whole system:

[0047] The printing platform consists of a printing X-axis travel track 1, and the work panel can slide along its length to provide a horizontal movement reference for component printing. The printing X-axis travel track 1 is parallel to the gantry X-axis travel track 2 on both sides. The gantry truss 3 spans above the printing platform and is slidably installed on the gantry X-axis travel track 2. It can move along the length of the track to achieve a wide range of movement coverage of the equipment in the X-axis direction.

[0048] Two sets of position adjustment components are installed on the crossbeam of the gantry truss 3. Each set moves along the Y-axis direction of the crossbeam length by sliding the Y-axis slide rail 4 and the Y-axis slide block 5. The limit seat 8 on the Y-axis slide block 5 is equipped with a Z-axis slide rail 9. The Z-axis motor 31 drives the second gear to mesh with the Z-axis rack 10, which drives the Z-axis slide rail 9 to move along the Z-axis direction of the crossbeam height, providing precise three-dimensional position adjustment for the actuator. A rotating connecting plate 28 is installed at the bottom of the Z-axis slide rail 9 of one set of position adjustment components. The printing extrusion device 29 is fixed through the rotating connecting plate 28 and can adjust the printing angle with the rotating connecting plate 28. A universal milling cutter head 30 is directly installed at the bottom of the Z-axis slide rail 9 of the other set of position adjustment components to realize the trimming function.

[0049] The gantry truss 3 is equipped with a material tank 11 for storing printing materials; the bottom surface is equipped with an electrical cabinet 12, an operating table 13, a water chiller 14, a compressed air storage tank 15 and an air compressor 16, which respectively provide power control, operation interaction, equipment cooling and compressed air supply.

[0050] The overall working principle is as follows:

[0051] When the material in the hopper 11 is insufficient, the gantry truss 3 slides along the X-axis travel track 2 of the gantry to the support 17 at the end of its path; the cylinder 18 at the top of the support 17 is activated, and its telescopic end pushes the feeding pipe 19 to move, so that the feeding male head 20 at one end of the feeding pipe 19 connects with the feeding female head 24 at the end of the feeding pipe 23 of the hopper 11; the first vacuum feeder 27 is activated, and the composite material in the hopper 21 is transported to the hopper 11 through the feeding pipe 23 via the feeding pipe 23 through the feeding pipe 23 and the matching structure of the feeding pipe 19, the feeding male head 20 and the feeding female head 24; the stirring motor 22 on the top surface of the hopper 11 drives the internal stirring shaft to rotate, so as to uniformly stir the material, avoid the material from clumping, and accelerate the drying efficiency of the material; at the same time, the printing parameters are set through the operating table 13, and the electrical cabinet 12 controls the Y-axis motor 7, Z-axis motor 31, etc. to perform initialization and debugging to ensure that the motion accuracy of the gantry truss 3, the position adjustment component and the execution component meets the requirements.

[0052] After printing begins, the work panel moves along the X-axis travel track 1 along a preset path, while the gantry truss 3 adjusts its position synchronously along the X-axis travel track 2 to achieve wide coverage in the X-axis direction; the Y-axis motor 7 drives the first gear to mesh with the Y-axis rack 6, driving the Y-axis slide 5 to move along the Y-axis slide rail 4, adjusting the position of the printing extrusion device 29 in the Y-axis direction; the Z-axis motor 31 drives the second gear to mesh with the Z-axis rack 10, driving the Z-axis slide rail 9 to move along the height direction, controlling the printing layer height of the printing extrusion device 29; the rotating connecting plate 28 can adjust the printing angle of the printing extrusion device 29 according to the complex structural requirements of the component, realizing the forming of complex irregular structures;

[0053] The second vacuum feeder 26 is started, and the uniformly stirred material in the material tank 11 is conveyed to the printing extrusion device 29 through the bottom conveying tank path. The printing extrusion device 29 extrudes the material according to preset parameters and accumulates it layer by layer on the working panel to form the preliminary shape of the composite material component. During the process, the water cooler 14 provides cooling for the printing extrusion device 29 to prevent the heat of the printing extrusion device 29 from being conducted upward, to prevent the servo system of the printing extrusion device 29 from failing, and to ensure printing quality.

[0054] Once a layer or the entire component has been printed, there is no need to disassemble or transfer the component. The system can be switched to trimming mode directly via the control panel 13. The control cabinet 12 controls the gantry truss 3 to move along the gantry X-axis travel track 2, while simultaneously adjusting another set of position adjustment components: the Y-axis motor 7 drives the corresponding Y-axis slide 5 to move along the Y-axis slide rail 4, and the Z-axis motor 31 drives the corresponding Z-axis slide rail 9 to move the universal milling cutter head 30 precisely to the position where the component needs trimming. The universal milling cutter head 30 is activated according to the trimming requirements. It can achieve multi-directional angle adjustment and, in conjunction with the X-axis movement of the gantry truss 3 and the Y-axis and Z-axis movements of the position adjustment components, performs cutting trimming on the surface and local structure of the component. During the process, the compressed air storage tank 15 and the air compressor 16 provide compressed air to promptly clean up the waste generated during trimming, preventing the waste from affecting the trimming accuracy and the surface quality of the component. The compressed air can also provide a power source for loading.
