Description
Technical Field
[0001] The present invention belongs to the technical field of printing equipment, and in particular relates to a high-precision three-dimensional printing equipment and method. Background Art
[0002] In the manufacturing industry, traditional production and manufacturing methods often require complex mold design and manufacturing processes, with long cycles and high costs. In addition, it is difficult to achieve precise manufacturing for some parts with complex shapes and fine structures. The emergence of 3D printing technology allows manufacturers to quickly and flexibly produce customized parts, greatly shortening the product development cycle, reducing production costs, and improving production efficiency. In the aerospace field, many parts need to be lightweight, high-strength, and have complex internal structures. 3D printing technology can meet these special requirements, realize integrated manufacturing of parts, reduce the number of parts, and improve overall performance.
[0003] Most of the operating tables in existing equipment are not equipped with anti-collision components, so when a collision occurs, the print head nozzle may be deformed, blocked or even broken, making it impossible to extrude the printing material normally, affecting the printing quality. In severe cases, the device will be directly scrapped and cannot be used. At the same time, the drive device and connecting parts of the print head may also become loose or damaged due to the collision, resulting in a decrease in the movement accuracy of the print head and position deviation in subsequent printing. Summary of the invention
[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a high-precision three-dimensional printing device and method.
[0005] The technical solution adopted to solve the above technical problems is: a high-precision three-dimensional printing device, comprising a first profile, a second profile is fixedly connected to one side of the outer wall of the first profile, a first connecting plate is fixedly connected between the top of the first profile and the second profile, and an operation screen and a data box are fixedly connected to the top of the first connecting plate;
[0006] A Z-axis transmission assembly is installed on the top of the first profile, a fourth profile is fixedly connected to one side of the rear end of the second profile, a Y-axis transmission assembly is installed on the Z-axis transmission assembly, and an anti-collision operating table assembly is fixedly connected to the top of the Y-axis transmission assembly;
[0007] An X-axis transmission assembly is installed on the top of the Z-axis transmission assembly, a second fixed block is fixedly connected to the bottom of the X-axis transmission assembly, and a printing gun is installed on the bottom of the second fixed block.
[0008] Furthermore, the Z-axis transmission assembly includes a third profile fixedly connected to the top of the first profile, a first connecting piece fixedly connected to one side of the outer wall of the third profile, two first bolts threadedly connected between the third profile and the first connecting piece, a first motor is installed at the bottom of the first connecting piece, an adapter is installed at the output end of the first motor, a threaded rod is fixedly connected to the top of the inner wall of the adapter, two mounting plates are fixedly connected to one side of the outer wall of the third profile, a guide rod is fixedly connected between the inner walls of the two mounting plates, the threaded rod passes through the two mounting plates, a mounting block is slidably connected between the two guide rods and the outer walls of the threaded rod, and a fixing plate is fixedly connected to one side of the outer wall of the mounting block.
[0009] Through the above technical solution, the first motor is started first, so that the first motor drives the adapter to rotate, and then the adapter drives the threaded rod to rotate synchronously along the inner walls of the two bearings. At the same time, the threaded rod will also drive the mounting block to move up and down along the two guide rods, and then the mounting block drives the fixed plate to move synchronously.
[0010] Furthermore, bearings are fixedly connected to the two mounting plates, and the threaded rod passes through the centers of the two bearings.
[0011] Through the above technical solution, the friction force of rolling friction is small, which can effectively reduce the wear of the contact part between the threaded rod and the mounting plate, extend the service life of the threaded rod and the mounting plate, and reduce maintenance costs.
[0012] Furthermore, the Y-axis transmission assembly includes a T-shaped profile fixedly connected to one side of the outer wall of the first profile, the top of the T-shaped profile is fixedly connected to a first guide rail, the rear end of the T-shaped profile is fixedly connected to a second connecting piece, a second motor is installed on the inner side of the second connecting piece, the output end of the second motor is fixedly connected to a first driving wheel, a first rotating rod is fixedly connected to one side of the front end of the outer wall of the T-shaped profile, the outer wall of the first rotating rod is rotatably connected to a first driven wheel, a first transmission belt is installed between the first driving wheel and the inner wall of the first driven wheel, the outer wall of the first guide rail is slidably connected to a first slider, and one side of the outer wall of the first slider is fixedly connected to two first linkage parts.
[0013] Through the above technical solution, the second motor is first started so that the second motor drives the first driving wheel, and then the first driving wheel drives the first transmission belt to rotate. At the same time, due to the friction between the first driven wheel and the first transmission belt, the first driven wheel can move synchronously, and then the first transmission belt drives the two first linkage members to rotate synchronously, and then the two first linkage members drive the first slider to move back and forth.
[0014] Furthermore, the inner walls of the two first linkage members are tightly fitted to the surfaces corresponding to the first transmission belt, and two first bolts are threadedly connected between the two first linkage members.
[0015] Through the above technical solution, the power of the transmission belt can be efficiently transmitted to the first linkage member, thereby driving the first slider to move forward and backward, achieving stable and efficient power transmission and ensuring the normal operation of the Y-axis transmission assembly.

[0017] Through the above technical solution, when a collision occurs, the printing plate will be subjected to downward pressure, and then the printing plate will drive the support plate to move downward along the outer walls of multiple mounting pins. At the same time, multiple buffer springs will also be squeezed and deformed, thereby reducing the stress between collisions.
[0018] Furthermore, the second connecting plate and the supporting plate are parallel to each other, and the plurality of mounting pins and buffer springs are vertically arranged between the second connecting plate and the inner wall of the supporting plate.
[0019] Through the above technical solution, it can be ensured that when subjected to external force impact, the pressure transmitted to the pallet by the printing plate is evenly distributed on the entire pallet. At the same time, the vertical setting can more effectively convert the kinetic energy generated by the impact into the elastic potential energy of the buffer spring, thereby significantly reducing the stress between impacts and improving the anti-collision effect.
[0020] Furthermore, the X-axis transmission assembly includes a fifth profile fixedly connected between the third profile and the top of the fourth profile, a third connecting piece is fixedly connected to the top of one side of the outer wall of the third profile, a third motor is installed on the inner wall of the third connecting piece, a second driving wheel is fixedly connected to the output end of the third motor, a first fixed block is fixedly connected to the top of one side of the outer wall of the fourth profile, a second rotating rod is fixedly connected to the rear end of the first fixed block, a second driven wheel is rotatably connected to the outer wall of the second rotating rod, a second transmission belt is arranged between the outer walls of the second driving wheel and the second driven wheel, a second guide rail is fixedly connected to the bottom of the fifth profile, a second slider is slidably connected to the outer wall of the second guide rail, two second linkage members are fixedly connected to the rear end of the second slider, and two second bolts are threadedly connected between the two second linkage members.
[0021] Through the above technical solution, the third motor is first started, so that the third motor drives the corresponding second driving wheel to rotate. At the same time, the second driving wheel also drives the second transmission belt to rotate synchronously. Since the second transmission belt generates friction on the outer wall of the second driven wheel while rotating, the second driven wheel will rotate along the outer wall of the second rotating rod. Then the second transmission belt will also drive the two second linkage members to move synchronously, and then the two second linkage members will drive the second slider to move synchronously, and then the second slider will also drive the second fixed block and the print gun to move synchronously.
[0022] A method for using a high-precision three-dimensional printing device comprises the following specific steps:
[0023] Step 1: First, start the first motor, so that the first motor drives the adapter to rotate, and then the adapter drives the threaded rod to rotate synchronously along the inner walls of the two bearings. At the same time, the threaded rod also drives the mounting block to move up and down along the two guide rods, and then the mounting block drives the fixing plate to move synchronously;
[0024] Step 2: Start the second motor, so that the second motor drives the first driving wheel, and then the first driving wheel drives the first transmission belt to rotate. At the same time, due to the friction between the first driven wheel and the first transmission belt, the first driven wheel can move synchronously, and then the first transmission belt drives the two first linkage members to rotate synchronously, and then the two first linkage members drive the first slider to move forward and backward;
[0025] Step 3: Start the third motor, so that the third motor drives the corresponding second driving wheel to rotate. At the same time, the second driving wheel also drives the second transmission belt to rotate synchronously. Since the second transmission belt generates friction on the outer wall of the second driven wheel while rotating, the second driven wheel will rotate along the outer wall of the second rotating rod. Then the second transmission belt will also drive the two second linkage members to move synchronously. Then the two second linkage members will drive the second slider to move synchronously. Then the second slider will also drive the second fixed block and the print gun to move synchronously.
[0026] Step 4: When a collision occurs, the print plate will be subjected to downward pressure, and then the print plate will drive the pallet to move downward along the outer walls of multiple mounting pins. At the same time, multiple buffer springs will also be squeezed and deformed, thereby reducing the stress between collisions.
[0027] The beneficial effects of the present invention are as follows: (1) The present invention can absorb most of the impact force at the moment of collision by setting an anti-collision operating table assembly, effectively reduce the damage to components such as the print head, screw, guide rail, etc., extend the service life of the equipment, and reduce the maintenance cost and equipment downtime caused by hardware damage; (2) The present invention sets a Z-axis transmission assembly, a Y-axis transmission assembly and an X-axis transmission assembly. The X-, Y- and Z-axis transmission assemblies are respectively responsible for the movement of the equipment in three mutually perpendicular directions. They work together to construct a complete three-dimensional space, which enables the print head to move freely in the three-dimensional space, so that objects of various complex shapes and structures can be printed.

9. A method for using a high-precision three-dimensional printing device according to any one of claims 1 to 8, characterized in that: The specific steps include: Step 1: First, start the first motor (604), so that the first motor (604) drives the adapter (605) to rotate, and then the adapter (605) drives the threaded rod (606) to rotate synchronously along the inner walls of the two bearings. At the same time, the threaded rod (606) also drives the mounting block (609) to move up and down along the two guide rods (608), and then the mounting block (609) drives the fixing plate (6010) to move synchronously. Step 2: Start the second motor (804), so that the second motor (804) drives the first driving wheel (805), and then the first driving wheel (805) drives the first transmission belt (808) to rotate. At the same time, due to the friction between the first driven wheel (807) and the first transmission belt (808), the first driven wheel (807) can move synchronously, and then the first transmission belt (808) drives the two first linkage members (8010) to rotate synchronously, and then the two first linkage members (8010) drive the first slider (809) to move forward and backward; Step 3: Start the third motor (1003), so that the third motor (1003) drives the corresponding second driving wheel (1004) to rotate. At the same time, the second driving wheel (1004) also drives the second transmission belt (1008) to rotate synchronously. Since the second transmission belt (1008) generates friction on the outer wall of the second driven wheel (1007) while rotating, the second driven wheel (1007) will rotate along the outer wall of the second rotating rod (1006). Then the second transmission belt (1008) will also drive the two second linkage members (1011) to move synchronously. Then the two second linkage members (1011) will drive the second slider (1010) to move synchronously. Then the second slider (1010) will also drive the second fixed block (11) and the printing gun (12) to move synchronously. Step 4: When a collision occurs, the printing plate (905) will be subjected to downward pressure, and then the printing plate (905) will drive the support plate (903) to move downward along the outer wall of the multiple mounting pins (902). At the same time, the multiple buffer springs (904) will also be squeezed and deformed, thereby reducing the stress between collisions.
