Description

Technical Field

[0001] This utility model relates to the field of leveling components, specifically a leveling component for a 3D printer. Background Technology

[0002] 3D printing, a type of rapid prototyping technology, is a technique that uses digital model files as a basis and employs powdered metals or plastics and other bondable materials to construct objects layer by layer. In actual 3D printing operations, the flatness of the printing platform directly affects the quality of the printed sample. If any abnormalities in the platform's flatness are found, the platform's levelness needs to be adjusted promptly.

[0003] Existing printing platforms have adjustment supports at each of their four corners. When the platform is not level, each of these supports needs to be adjusted individually. The adjustment method involves loosening bolts on the supports, which raises and lowers the bolts to adjust the platform's level. Since multiple bolts need to be adjusted one by one, the process is quite cumbersome. Therefore, we propose a 3D printer leveling component. Utility Model Content

[0004] This invention provides a 3D printer leveling component that allows the support platform to rotate in any direction with the second support axis as the support point, facilitating leveling and solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A 3D printer leveling component is designed, including a second support shaft. Multiple first support shafts are arranged in a ring around the second support shaft and are parallel to it. The top of the first support shaft and the second support shaft are provided with omnidirectional ball heads. The top of the omnidirectional ball heads are respectively installed below the support platform. Each first support shaft is movably placed inside a support tube. A fastening device is provided on the support tube to adjust the first support shaft to a preset height. The sides of the support tube are respectively connected to the mounting plate through support legs, and the bottom of the second support shaft is installed on the mounting plate.

[0006] Preferably, a support frame is installed at the bottom of the support platform, a cross is provided in the middle of the support frame, the second support axis is located at the center of the cross, and the first support axis is distributed at the four corners of the support frame.

[0007] Preferably, the mounting plate is a frame structure, with a strip seat installed in the middle of the frame structure, and the bottom of the second support shaft is connected to the strip seat.

[0008] Preferably, the bottom of the second support shaft and the support leg are respectively equipped with connecting seats, and the connecting seats are detachably connected to the four corners of the strip seat and the mounting plate.

[0009] Preferably, the positioning device includes an annular groove at the top of the support tube, and the support tube at the annular groove has at least one tightening port passing through its central axis. A quick-release tube clamp is provided in the annular groove to tighten the tightening port.

[0011] Preferably, a level is provided on the surface of the support platform, and the level is embedded in the surface of the support platform.

[0012] Compared with the prior art, this utility model requires that each first support shaft be loosened before leveling the support platform, so that each first support shaft can move freely up and down. The operator can then hold the support platform to make adjustments, allowing the support platform to rotate in any direction with the second support shaft as the support point. Once the support platform is level, each first support shaft can be fixed. The operation is simple and convenient. Attached Figure Description

[0020] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Reference Figures 1 to 5 This utility model provides a technical solution: a 3D printer leveling component, including a support platform 1, a support frame 2 installed at the bottom of the support platform 1, and a cross 10 provided in the middle of the support frame 2. Both the support frame 2 and the cross 10 are connected to the support platform 1, serving to strengthen the structural strength of the support platform 1 and prevent deformation during use. A mounting plate 7 is provided below the support platform 1. The mounting plate 7 has a frame structure, and a strip seat 3 is installed in the middle of the frame structure. In actual use, the mounting plate 7 is simply fastened to the printer with bolts.

[0022] This application also includes a second support shaft 11 disposed below the support platform 1, with multiple parallel first support shafts arranged in a ring around the second support shaft 11, such as... Figure 2 and Figure 3 As shown, a spherical head 13 is provided at the top of both the first support shaft 8 and the second support shaft 11. The top of the spherical head 13 is installed below the support platform 1. Specifically, the second support shaft 11 is located at the center of the cross 10, while the first support shaft 8 is distributed at the four corners of the support frame 2. The bottom of the second support shaft 11 is connected to the strip seat 3. During installation, the spherical head 13 at the top of the second support shaft 11 is connected to the center of the cross 10, and the spherical head 13 at the top of the first support shaft 8 is connected to the four corners of the support frame 2.

[0023] In this application, as Figure 2 and Figure 3 As shown, each first support shaft 8 is movably placed inside the support tube 4, and the sides of the support tube 4 are connected to the mounting plate 7 via support legs 6, and the bottom of the second support shaft 11 is mounted on the mounting plate 7.

[0024] Based on the above embodiments, the number of first support shafts 8 can be four. When the first support shafts 8 are not fixed, the entire leveling assembly works as follows: the support platform 1 can rotate in any direction with the second support shaft 11 as the support point, that is, by holding the edge of the support platform 1, it can be rotated around the top of the second support shaft 11.

[0025] A level 9 is provided on the surface of the support platform 1. The level 9 is two mutually perpendicular cylindrical spirit levels or circular spirit levels. The level 9 is located at the corner of the support platform 1 and is embedded in the surface of the support platform 1, so that the top of the support platform 1 and the level 9 are flush. When the support platform 1 is rotated, the level 9 can be observed to determine whether the entire support platform 1 is level, which can provide a reference for leveling the support platform 1.

[0026] Based on the above embodiments, the specific leveling process is as follows: Figure 5 As shown, when the support platform 1 tilts to one side, simply loosen each of the first support shafts 8 to prevent any of the first support shafts 8 from getting stuck. Then, the operator can hold the support platform 1 and adjust it. Once the support platform 1 is level, the first support shafts 8 can be fixed, and the support platform 1 will be leveled.

[0027] Therefore, the support tube 4 is equipped with a fastening device that can adjust the first support shaft 8 to a preset height, such as... Figure 4 As shown, the positioning device includes an annular groove 14 at the top of the support tube 4. The support tube 4 at the annular groove 14 has at least one tightening port 15 passing through its central axis. A quick-release tube clamp 12 is provided in the annular groove 14 to tighten the tightening port 15. When the quick-release tube clamp 12 is closed, it can drive the support tube 4 at the tightening port 15 to retract inward, thereby clamping the first support shaft 8. When the quick-release tube clamp 12 is released, the shape of the support tube 4 at the tightening port 15 returns to its original shape due to elastic potential energy, and the first support shaft 8 can move. The first support shaft 8 is fixed by the quick-release tube clamp 12, which is convenient for disassembly and fastening.

[0028] However, in this application, the positioning device can also be a locking bolt threaded onto the support tube 4. Tightening the locking bolt can abut against the first support shaft 8, which can also fix the first support shaft 8.

[0029] Based on the above embodiments, further optimization can be made. In order to facilitate the disassembly of the second support shaft 11 and the support leg 6, a connecting seat 5 is installed at the bottom of the second support shaft 11 and the support leg 6 respectively. The connecting seat 5 is detachably connected to the four corners of the strip seat 3 and the mounting plate 7 respectively, and each connecting seat 5 is fastened by bolts.

[0030] Based on the above embodiments, it should be further explained that the top edge of the real-world omnidirectional ball head 13 is provided with a flange, which can be fixed with bolts during installation.

[0031] Based on the above embodiments, it should be further explained that, as Figure 2As shown, during the actual leveling process, one of the four first support shafts 8 is fixed, and the other three are also fixed. Therefore, in actual operation, after the level of the support platform is adjusted, one of the first support shafts 8 can be fixed first, and then the other three first support shafts 8 can be driven.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
