Description

Technical Field

[0001] This utility model relates to the field of 3D printing equipment technology, specifically to a post-processing device for optimizing the internal structure of 3D printed objects. Background Technology

[0002] The post-processing of the internal structure optimization of 3D printed objects includes steps such as removing internal powder, heat treatment, and stress relief. Among these, internal deburring and polishing are key steps. Internal burrs are removed by precise cutting, and then polished with tools such as sandpaper to ensure that the final quality of the printed parts meets expectations.

[0003] A search revealed that in existing technologies, the cutting tools used for post-processing optimization of the internal structure of 3D printed objects are often designed as fixed or integrated pieces. This means that once the cutting tool is damaged or needs to be replaced to accommodate 3D printed objects of different sizes, users typically have to directly replace it with a different cutting tool to meet their needs. This is not only complex to operate but also increases maintenance costs and time. Furthermore, the extension length of the cutting tool in existing technologies is often fixed. When dealing with 3D printed objects of different depths and shapes, it is often necessary to replace the cutting tool with one of the same size but a different length to trim the internal structure. Therefore, this paper provides a post-processing device for optimizing the internal structure of 3D printed objects to solve the above problems. Utility Model Content

[0022] To make the above-mentioned contents, objectives, and beneficial effects of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] It should be noted that, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] Reference Figures 1 to 5 In this embodiment of the present invention, a post-processing device for optimizing the internal structure of a 3D printed object includes: a handheld grip 1, with a slider hole 2 and a pull rope hole 3 on the side of the handheld grip 1; multiple sets of positioning grooves 4 evenly distributed on the side of the handheld grip 1; an upper connecting hole 5 penetrating to its internal cavity on the top of the handheld grip 1; an inner fixing block 6 disposed in the inner cavity of the handheld grip 1; an upper positioning circular groove 7 disposed above the inner fixing block 6; a spring groove 8 disposed inside the upper positioning circular groove 7; a top column convex groove 9 disposed on the side of the inner fixing block 6; a first spring 10 fixedly connected to the inside of the spring groove 8; an arc-shaped groove block 11 fixedly connected above the first spring 10; a second spring 12 fixedly connected to the inside of the top column convex groove 9; a movable top column 13 fixedly connected to the other end of the second spring 12; a pull rope 14 fixedly connected to the other end of the movable top column 13; and a positioning slider 15 fixedly connected to the side of the inner fixing block 6. Two sets of top block convex grooves 16 are provided on the inner side of the slider 15. A convex top block 17 is provided on the inner side of the top block convex groove 16. A third spring 18 is sleeved on the outer side of the convex top block 17. A connecting block 19 is fixedly connected to the short radius cylinder of the convex top block 17 through the narrow opening of the top block convex groove 16. A cutting blade 20 is provided above the hand grip 1. A connecting block 21 is fixedly connected below the cutting blade 20. A positioning hole 22 is provided on the side of the connecting block 21. When the connecting block 21 is inserted into the spring groove 8, it will push the arc groove block 11 to move, thereby compressing the first spring 10. At the same time, the movable top column 13 slides along the arc surface of the arc groove block 11 under the action of the second spring 12 until the second spring 12 is reset. The movable top column 13 slides into the positioning hole 22 and fixes the cutting blade 20. When the cutting blade 20 needs to be removed, pull the pull rope 14 to make the movable top column 13 slide out of the positioning hole 22, and the cutting blade 20 can be easily removed.

[0025] The narrow opening of the top column convex groove 9 is connected to the spring groove 8, ensuring that the movable top column 13 can move freely in the spring groove 8, and can slide along the arc surface of the arc groove block 11 to realize the fixing and release of the cutting tool 20.

[0026] When the second spring 12 contracts naturally without external force, the rounded front end of the movable top column 13 abuts against the lowest point of the arc groove of the arc groove block 11. The pull rope 14 extends out to the outside of the hand grip 1 through the pull rope hole 3, making it convenient for the user to pull the pull rope 14 to release the cutting blade 20, thus improving the ease of operation. The positioning slider 15 extends out to the outside of the hand grip 1 through the slider hole 2. The user can adjust the position of the inner fixing block 6 by pushing the positioning slider 15, thereby adjusting the length of the cutting blade 20.

[0027] The long-radius cylinder of the convex top block 17 is adapted to the positioning groove 4, and the short-radius cylinder of the convex top block 17 is adapted to the narrow opening of the top block convex groove 16. This design can ensure that the convex top block 17 can stably fix the position of the inner fixing block 6 when it is inserted into the positioning groove 4, and allow the convex top block 17 to move freely in the top block convex groove 16.

[0028] When the third spring 18 is naturally extended without external force, the long-radius cylinder of the convex top block 17 extends out of the top block convex groove 16 and inserts into the positioning groove 4. When the connecting block 19 is pulled, the third spring 18 can be compressed, so that the convex top block 17 is completely retracted into the top block convex groove 16. When the third spring 18 is in a naturally extended state, the long-radius cylinder of the convex top block 17 will extend out of the top block convex groove 16 and insert into the positioning groove 4, thereby fixing the position of the inner fixing block 6. When it is necessary to adjust the position of the inner fixing block 6, the connecting block 19 can be pulled to compress the third spring 18 and completely retract the convex top block 17 into the top block convex groove 16. At this time, the positioning slider 15 can be pushed to adjust the position of the inner fixing block 6.

[0029] The connecting block 21 is adapted to the spring groove 8, and the positioning hole 22 is adapted to the movable top post 13. The adaptation of the connecting block 21 to the spring groove 8 can ensure that the cutting blade 20 can be stably inserted and fixed on the hand grip 1; while the adaptation of the positioning hole 22 to the movable top post 13 can realize the fixing and release of the cutting blade 20.

[0030] The working principle of this utility model is as follows: When it is necessary to fix the cutting blade 20, the user only needs to align the connecting block 21 below the cutting blade 20 with the upper connecting hole 5 above the hand grip 1 and slowly insert it. After the connecting block 21 enters the spring groove 8, it will push the arc-shaped groove block 11 to move downward, thereby compressing the first spring 10. At the same time, the movable top post 13 slides along the arc surface of the arc-shaped groove block 11 under the action of the second spring 12. As the arc-shaped groove block 11 descends, the movable top post 13 will slide along the arc surface of the arc-shaped groove block 11 and gradually approach the positioning hole 22. At this time, the second spring 12 is continuously stretched. When the connecting block 21 is fully inserted into the spring groove 8, the second spring 12 returns to its original position, pushing the movable top post 13 to slide into the positioning hole 22, thereby fixing the cutting blade 20 on the hand grip 1.

[0031] If the length of the cutting blade 20 needs to be adjusted, the user first pulls the connecting block 19 to compress the third spring 18, and the convex top block 17 is fully retracted into the convex groove 16 of the top block, thereby releasing the fixation of the inner fixing block 6. Then, the user pushes the positioning slider 15 and slides it through the slider hole 2 on the outside of the hand grip 1, causing the inner fixing block 6 and the cutting blade 20 to move up and down together. When the cutting blade 20 extends to the required length, the connecting block 19 is released, and the positioning slider 15 is moved back and forth slightly until the third spring 18 is reset. The convex top block 17 is pushed out of the convex groove 16 of the top block and inserted into the corresponding positioning groove 4, thereby re-fixing the position of the inner fixing block 6.

[0032] When it is necessary to disassemble or replace the cutting blade 20 of different sizes and models, the user pulls the pull rope 14 that extends to the outside of the hand grip 1, so that the movable top post 13 slides out of the positioning hole 22. As the movable top post 13 slides out, the connecting block 21 under the cutting blade 20 loses its fixation, and the user can easily remove the cutting blade 20 from the hand grip 1.

[0033] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
