Description

Technical Field

[0001] This utility model particularly relates to a multifunctional 3D printer linkage mechanism. Background Technology

[0002] In existing 3D printing technologies, the movement mechanism of the printing platform is a crucial factor affecting print quality and equipment stability. Traditional 3D printers typically employ a simple guide rail and slider structure to move the printing platform. While this structure can meet basic printing needs, it has several significant drawbacks in practical use. First, traditional printing platform movement mechanisms lack effective overload protection. When material buildup, print head collisions, or other unexpected events occur during printing, the printing platform may be subjected to excessive loads, leading to guide rail deformation, slider damage, or even displacement of the entire printing platform, thereby affecting printing accuracy or even damaging the equipment. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a multifunctional 3D printer linkage mechanism.

[0004] To solve the aforementioned technical problems, this utility model adopts the following technical solution:

[0005] A multifunctional 3D printer linkage mechanism includes a frame, a print head at the upper end of the frame, a movable printing platform below the print head, two sets of guide rails symmetrically arranged at the lower end of the frame, a square tube connected to each set of guide rails via a sliding block, a mounting base for mounting the printing platform on the square tube, a positioning post connected to the printing platform, one end of the positioning post passing through the mounting base and extending into the square tube and connected to a locking element, a driving inclined surface on the positioning post, an inclined surface transmission mechanism movably mounted on the square tube, and a position sensor connected to the outer wall of the square tube. When the printing platform is overloaded, the positioning post drives the driving inclined surface downward, pushes the inclined surface transmission mechanism to move laterally, and triggers the position sensor to issue an alarm signal.

[0006] Preferably, the inclined plane transmission mechanism includes a crossbar slidably disposed on the side wall of the square tube. One end of the crossbar is provided with a transmission inclined plane that matches the driving inclined plane, and the other end is provided with a trigger. When the driving inclined plane acts on the transmission inclined plane, the crossbar drives the trigger to move laterally to trigger the position sensor.

[0007] Preferably, a positioning ring is fixed on the crossbar, and a spring is wound around the crossbar between the inner wall of the square tube and the positioning ring. One end of the spring is connected to the positioning ring, and the other end is connected to the inner wall of the square tube.

[0008] Preferably, a connecting plate is slidably provided on the upper end of the frame, a print head is fixedly provided on the connecting plate, and a drive cylinder is connected to the connecting plate. The drive cylinder drives the connecting plate to move up and down along the frame to adjust the distance between the print head and the printing platform.

[0009] Preferably, the square tube is provided with a rubber ring, and the rubber ring has an opening for the positioning post to pass through.

[0010] Preferably, the locking element is a bolt.

[0011] The beneficial effects of this utility model are:

[0012] This invention can promptly detect and issue an alarm when the printing platform is overloaded. The inclined plane transmission mechanism converts the vertical overload pressure into lateral movement, triggering the position sensor to issue an alarm signal, reminding the operator to take measures, effectively preventing equipment damage, and improving the safety and service life of the equipment. In addition, the rubber ring not only provides cushioning and shock absorption for the positioning column, reducing vibration generated during the movement of the printing platform, but also further enhances the stability and reliability of the equipment. This multi-functional design combining overload protection and shock absorption allows this invention to adapt to various complex working conditions, ensuring that the equipment maintains efficient and stable operation in different printing tasks, significantly improving the overall performance and applicability of the 3D printer.

[0021] A multifunctional 3D printer linkage mechanism includes a frame 1, a print head 2 at the upper end of the frame 1, a movable print platform 3 below the print head 2, two sets of guide rails 4 symmetrically arranged at the lower end of the frame 1, a square tube 6 connected to each set of guide rails 4 via a sliding block 5, a mounting seat 60 for mounting the print platform 3 on the square tube 6, a positioning post 8 connected to the print platform 3, one end of the positioning post 8 passing through the mounting seat 60 and extending into the square tube 6 and connected to a locking member 9, a driving inclined surface 101 on the positioning post 8, an inclined surface transmission mechanism 11 movably arranged on the square tube 6, and a position sensor 12 connected to the outer wall of the square tube 6. When the print platform 3 is overloaded, the positioning post 8 drives the driving inclined surface 101 to move downward, pushes the inclined surface transmission mechanism 11 to move laterally, and triggers the position sensor 12 to issue an alarm signal.

[0022] Furthermore, the inclined plane transmission mechanism 11 includes a horizontal bar 111 slidably disposed on the side wall of the square tube 6. One end of the horizontal bar 111 is provided with a transmission inclined plane 112 that matches the driving inclined plane 101, and the other end is provided with a trigger 113. When the driving inclined plane 101 acts on the transmission inclined plane 112, the horizontal bar 111 drives the trigger 113 to move laterally to trigger the position sensor 12.

[0023] Furthermore, a positioning ring 114 is fixed on the crossbar 111, and a spring 115 is wound around the crossbar 111 between the inner wall of the square tube 6 and the positioning ring 114. One end of the spring 115 is connected to the positioning ring 114, and the other end is connected to the inner wall of the square tube 6.

[0024] Furthermore, a connecting plate 7 is slidably provided on the upper end of the frame 1, a print head 2 is fixedly provided on the connecting plate 7, and a drive cylinder is connected to the connecting plate 7. The drive cylinder drives the connecting plate 7 to move up and down along the frame 1 to adjust the distance between the print head 2 and the printing platform 3.

[0025] Furthermore, the square tube 6 is provided with a rubber ring 13, and the rubber ring 13 has an opening 131 for the positioning post 8 to pass through.

[0026] Furthermore, the locking element 9 is a bolt.

[0027] The working principle of this utility model is as follows:

[0028] A positioning post 8 is installed at the bottom of the printing platform 3. One end of the positioning post 8 passes through the mounting base 60 and extends into the square tube 6, and is locked in place by bolts to ensure a stable connection between the printing platform 3 and the square tube 6. Two sets of guide rails 4 are symmetrically installed at the lower end of the frame 1. The guide rails 4 are linear guide rails to ensure the smoothness and accuracy of the movement of the printing platform 3. The sliding block 5 is slidably installed on the guide rail 4 and fixedly connected to the square tube 6, allowing the square tube 6 to slide smoothly along the guide rail 4. The focus of this application is on the inclined plane transmission mechanism 11, whose working principle is as follows:

[0029] A groove is made on the side wall of the square tube 6, and the crossbar 111 is slidably installed in the groove. One end of the crossbar 111 is machined into a transmission inclined surface 112 that matches the drive inclined surface 101, and the other end is equipped with a trigger element 113, such as a metal contact or a magnet. A positioning ring 114 is installed on the crossbar 111, and a spring 115 is wound around the crossbar 111 between the positioning ring 114 and the inner side wall of the square tube 6. One end of the spring 115 is connected to the positioning ring 114, and the other end is fixed to the inner side wall of the square tube 6. A position sensor 12 is installed on the outer wall of the square tube 6. The position sensor 12 can be implemented by a proximity switch or a photoelectric sensor, and its sensing end corresponds to the trigger element 113. When the crossbar 111 moves laterally, the trigger element 113 triggers the position sensor 12, and the position sensor 12 emits an alarm signal. When the printing platform 3 is overloaded, the positioning column 8 is subjected to downward pressure, which drives the drive inclined surface 101 to move downward. The driving inclined plane 101 contacts and interacts with the transmission inclined plane 112, pushing the crossbar 111 to move laterally. As the crossbar 111 moves, the trigger 113 activates the position sensor 12, which then issues an alarm signal to alert the operator to take timely measures to prevent equipment damage. Subsequently, the spring 115 returns to its original deformation, and the positioning ring 114 drives the crossbar 111 back to its original position.

[0030] Based on the above technical solution, this application installs a rubber ring 13 on the square tube 6, and opens an opening 131 on the rubber ring 13 for the positioning post 8 to pass through. The size of the opening 131 is slightly larger than the diameter of the positioning post 8 to ensure that the positioning post 8 can pass through the rubber ring 13 smoothly. At the same time, the rubber ring 13 can buffer and dampen the positioning post 8, reducing the vibration generated by the printing platform 3 during movement.

[0031] As an example 1, the locking member 9 can be implemented by bolts, which are threadedly connected to the positioning post 8 to firmly fix the positioning post 8 inside the square tube 6, ensuring that the printing platform 3 will not loosen during movement.

[0032] Based on the above technical solution, the frame 1 is made of high-strength aluminum alloy to ensure the stability and durability of the overall structure. The print head 2 is fixedly mounted on the connecting plate 7, which can be slidably mounted on the upper end of the frame 1 via a slide rail and slider structure. A drive cylinder is mounted on the top of the frame 1, and its piston rod is connected to the connecting plate 7. By controlling the extension and retraction of the drive cylinder, the print head 2 can move up and down along the frame 1, thereby adjusting the distance between the print head 2 and the printing platform 3.

[0033] This invention can promptly detect and issue an alarm when the printing platform is overloaded. The inclined plane transmission mechanism converts the vertical overload pressure into lateral movement, triggering the position sensor to issue an alarm signal, reminding the operator to take measures, effectively preventing equipment damage, and improving the safety and service life of the equipment. In addition, the rubber ring not only provides cushioning and shock absorption for the positioning column, reducing vibration generated during the movement of the printing platform, but also further enhances the stability and reliability of the equipment. This multi-functional design combining overload protection and shock absorption allows this invention to adapt to various complex working conditions, ensuring that the equipment maintains efficient and stable operation in different printing tasks, significantly improving the overall performance and applicability of the 3D printer.

Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
