Description

Technical Field

[0001] This utility model belongs to the field of 3D printer component technology, and in particular relates to a lifting structure for a 3D printer forming platform. Background Technology

[0002] The 3D printer's forming platform is the core component that supports the printed model during the 3D printing process. Located at the bottom of the printer or in the working area, it is directly opposite the nozzle (extruder) or laser / beam (such as SLA, DLP technology). Its main function is to provide a stable support surface for the printed model and ensure that each layer of material (such as plastic filaments, resin, or metal powder) can be precisely deposited to ultimately form a complete three-dimensional object.

[0003] Existing 3D printer molding platform lifting structures move the molding platform up and down, allowing it to be moved out of the printing cavity so that operators can remove the printed model. However, the existing lifting structure cannot be quickly disassembled from the molding platform, causing inconvenience for maintenance and replacement of both. To solve these problems, it is necessary to design a new 3D printer molding platform lifting structure. Summary of the Invention

[0004] This invention provides a lifting structure for a 3D printer molding platform to solve the aforementioned problems in the prior art.

[0005] This utility model is implemented as follows: a lifting structure for a 3D printer forming platform includes a mounting base, which is connected to an external printer by screws. A forming platform is provided on the upper end of the mounting base, and a ring platform is rotatably mounted on the forming platform. A groove is fixedly installed at one end of the bottom of the forming platform.

[0006] The mounting base has a movable seat at its upper end, and a driving mechanism is provided on the mounting base. The driving mechanism is used to drive the movable seat to move horizontally. The movable seat has an insert plate at its upper end, which is inserted into the groove. Vertical rods pass through both ends of the insert plate. The lower ends of the vertical rods are fixedly connected to the movable seat. The insert plate slides up and down along the vertical rods. A first servo motor is fixedly installed on the movable seat. A drive shaft is fixedly installed on the output shaft end of the first servo motor. A lead screw is fixedly installed on the upper end of the drive shaft. The lead screw is threadedly connected to the insert plate and passes through the insert plate.

[0007] As a preferred embodiment, the drive mechanism includes two spaced-apart guide rods that pass through the mounting base and are slidably mounted on it. One end of each guide rod is fixedly connected to a movable seat. A hydraulic rod is fixedly mounted on the mounting base, and the output end of the hydraulic rod is fixedly connected to the movable seat.

[0008] As a preferred embodiment, both the hydraulic rod and the first servo motor are controlled by an external controller.

[0009] As a preferred embodiment, a limiting plate is fixedly installed on the upper end of the drive shaft. The limiting plate is ring-shaped, and a ring-shaped buffer pad is fixedly connected to the limiting plate.

[0010] As a preferred embodiment, a limit block is fixedly installed at the upper end of the lead screw.

[0011] As a preferred embodiment, a second servo motor is fixedly mounted on the mounting base, and a bushing is fixedly mounted on the output end of the second servo motor. A spline groove is formed inside the bushing, and a connecting shaft is inserted into the bushing. The connecting shaft is provided with a spline, and the connecting shaft is splinedly connected to the bushing. An annular ring is fixedly mounted at the center of the bottom of the annular platform. A spline groove is formed inside the annular ring, and the upper end of the connecting shaft is inserted into the annular ring and the two are splinedly connected.

[0012] As a preferred embodiment, the lower end of the bushing is provided with a pressure balance hole.

[0013] Compared with related technologies, the lifting structure of the 3D printer forming platform provided by this utility model has the following beneficial effects: The hydraulic rod drives the movable seat to move horizontally, which in turn moves the insert plate on the movable seat horizontally to achieve insertion or removal of the plate into the groove at the bottom of the forming platform. This design allows for quick assembly and disassembly between the lifting structure and the forming platform. When the equipment malfunctions or parts need to be replaced, maintenance personnel can quickly separate the two and repair or replace the corresponding parts individually, greatly shortening maintenance time and improving the maintainability of the equipment.

[0014] A ring-shaped limiting plate fixedly mounted on the upper end of the drive shaft sets the limit position for the downward movement of the insertion plate. This prevents the insertion plate from disengaging from the lead screw, and the limiting block also prevents the insertion plate from detaching from the upper end of the lead screw. This ensures the normal movement of the insertion plate and the entire lifting structure. The ring-shaped buffer pad absorbs and disperses this impact force, reducing rigid collisions between components, extending the service life of the equipment, and reducing noise caused by collisions.

The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] A preferred embodiment of the lifting structure of the 3D printer molding platform provided by this utility model is, for example... Figures 1 to 4 As shown: A lifting structure for a 3D printer's forming platform includes a mounting base 1, which is connected to an external printer by screws. A forming platform 2 is mounted on the upper end of the mounting base 1, and a ring-shaped stage 3 is rotatably mounted on the forming platform 2. A groove 4 is fixedly mounted on one end of the bottom of the forming platform 2. The forming platform 2 and the ring-shaped stage 3 are located within a forming cavity 111, where printing takes place. After printing is complete, the lifting structure lowers the forming platform 2 and the ring-shaped stage 3, removing them from the forming cavity 111.

[0020] The upper end of the mounting base 1 is provided with a movable base 5. The mounting base 1 is provided with a drive mechanism, which is used to drive the movable base 5 to move horizontally. The upper end of the movable base 5 is provided with a plate 6, which is inserted into the slot 4. Vertical rods 7 pass through both ends of the plate 6. The lower end of the vertical rods 7 is fixedly connected to the movable base 5. The plate 6 slides up and down along the vertical rods 7. A first servo motor 8 is fixedly installed on the movable base 5. A drive shaft 9 is fixedly installed on the output shaft end of the first servo motor 8. A lead screw 10 is fixedly installed on the upper end of the drive shaft 9. The lead screw 10 is threadedly connected to the plate 6 and passes through the plate 6.

[0021] The drive mechanism includes two spaced-apart guide rods 11, which pass through the mounting base 1 and are slidably mounted on it. One end of each guide rod 11 is fixedly connected to a movable seat 5. A hydraulic rod 12 is fixedly mounted on the mounting base 1, and its output end is fixedly connected to the movable seat 5. Both the hydraulic rod 12 and the first servo motor 8 are controlled by an external controller.

[0022] In this embodiment, the hydraulic rod 12 in the drive mechanism operates under the control of an external controller, and the extension and retraction of its output end causes the movable seat 5 to move horizontally. Because the guide rod 11 passes through the mounting base 1 and is slidably mounted on the mounting base 1, and one end of the guide rod 11 is fixedly connected to the movable seat 5, the movable seat 5 can move horizontally smoothly along the guide rod 11 under the drive of the hydraulic rod 12.

[0023] When the movable seat 5 moves horizontally, it will drive the insert plate 6 to move horizontally, thereby allowing the insert plate 6 to be inserted into or removed from the groove 4. When the insert plate 6 is inserted into the groove 4, a connection is established between the lifting structure and the forming platform 2; when the insert plate 6 is removed from the groove 4, the two separate, facilitating the maintenance and replacement of the lifting structure and the forming platform 2.

[0024] The hydraulic rod 12 drives the movable seat 5 to move horizontally, causing the insert plate 6 on the movable seat 5 to move horizontally and be removed from the groove 4, thereby separating the insert plate 6 and the groove 4, realizing the disassembly of the lifting structure and the forming platform 2, and enabling the lifting structure and the forming platform 2 to be repaired and replaced.

[0025] Under the control of an external controller, the output shaft of the first servo motor 8 drives the drive shaft 9 to rotate, which in turn causes the lead screw 10, which is fixedly mounted on the upper end of the drive shaft 9, to rotate. When the lead screw 10 rotates, due to the thread action, the insert plate 6 moves up and down along the vertical rod 7. Since the insert plate 6 is inserted into the slot 4 and connected to the forming platform 2, the up and down movement of the insert plate 6 will cause the forming platform 2 to move up and down together, so that the forming platform 2 can be moved out of the printing cavity, so that the operator can take out the printed model on the forming platform, or move the forming platform back into the printing cavity for the next printing.

[0026] In a further preferred embodiment of this utility model: A limit plate 13 is fixedly installed on the upper end of the drive shaft 9. The limit plate 13 is ring-shaped, and a ring-shaped buffer pad 14 is fixedly connected to the limit plate 13. A limit block 15 is fixedly installed on the upper end of the lead screw 10.

[0027] An annular limiting plate 13, fixedly mounted on the upper end of the drive shaft 9, sets the limit position for the downward movement of the insertion plate 6. This prevents the insertion plate 6 from disengaging from the lead screw 10, while the limiting block 15 prevents the insertion plate 6 from detaching from the upper end of the lead screw 10. This ensures the normal movement of the insertion plate 6 and the entire lifting structure.

[0028] When the insert plate 6 moves downwards and contacts the limiting plate 13, the impact force generated by the movement may damage the insert plate 6, the limiting plate 13, and related connecting parts. The annular buffer pad 14 can absorb and disperse this impact force, reduce rigid collisions between components, extend the service life of the equipment, and reduce noise caused by the collision.

[0029] A second servo motor 16 is fixedly mounted on the mounting base 1. A bushing 17 is fixedly mounted on the output end of the second servo motor 16. A spline groove is formed inside the bushing 17, and a connecting shaft 18 is inserted into the bushing 17. The connecting shaft 18 has a spline and is splinedly connected to the bushing 17. An annular ring 19 is fixedly mounted at the center of the bottom of the annular platform 3. The annular ring 19 has a spline groove, and the upper end of the connecting shaft 18 is inserted into the annular ring 19 and splinedly connected to it. A pressure balancing hole 20 is formed at the lower end of the bushing 17. The pressure balancing hole 20 is used to balance the internal pressure of the bushing 17 with the external pressure.

[0030] The second servo motor 16 drives the bushing 17 to rotate, which in turn drives the connecting shaft 18 to rotate. The connecting shaft 18 then drives the annular stage 3 to rotate via the ring 19. The second servo motor 16 drives the annular stage 3 to rotate, causing the printed material on it to rotate, thereby adjusting the display direction of the printed material. The upper end of the connecting shaft 18 is detachable from the annular stage 19.
