Description

Technical Field

[0001] The utility model relates to the technical field of 3D carving and polishing, in particular to a surface polishing device for 3D carving finished products. Background Art

[0002] 3D engraving technology, as the name implies, is the process of designing a three-dimensional model through three-dimensional modeling software, and then using a 3D printer or other engraving equipment to materialize the model. In recent years, with the popularization of 3D printing technology and the reduction of costs, 3D engraving has gradually moved from the professional field to the public eye, becoming a tool for many people to show their creativity. After 3D engraving, the finished product needs to be polished on the surface. Generally, when polishing a flat surface, a common polishing machine can be used directly for polishing. Some 3D engraving products need to polish more arc surfaces, and the different radius of some arc surfaces requires different polishing heads.

[0003] In the prior art, most of the devices for polishing the surface of 3D engraving products are handheld polishing devices, mainly because the finished products of 3D engravings are often in irregular shapes. Therefore, the use of handheld polishing devices is convenient for staff to operate. When polishing the curved surface area of ​​the 3D engraving, a certain number of polishing wheels need to be prepared for use during polishing. Therefore, when dealing with curved surface areas with different curvatures and radii, the polishing wheels need to be replaced frequently, which affects the polishing efficiency. In addition, when directly using a polishing wheel for flat polishing, it takes a long time to polish the curved surface, which further affects the polishing efficiency. Utility Model Content

[0026] In this embodiment, the polishing machine body 1 is handheld, the mounting plate 2 is used to mount the support rod 3, and the adjusting member 5 is used to adjust the distance between the sliding plate 6 and the fixed plate 4. When adjusting the distance, the retracting member 8 will retract and release the polishing cloth 7, and the polishing cloth 7 will be in a stretched state. At this time, the arc surface of the finished engraving is clamped between the fixed plate 4 and the sliding plate 6, and the polishing cloth 7 is made to fit the arc surface of the finished engraving and then the polishing liquid is poured on it. When the polishing cloth 7 fits the arc surface of the finished engraving, a certain force needs to be applied to further increase the contact area between the polishing cloth 7 and the finished engraving. Then, the polishing machine body 1 is started to drive the rotation of the mounting plate 2 and the support rod 3, and then the arc surface of the finished engraving is polished, so that the polishing cloth 7 is directly fitted to the arc surface and only needs to follow the arc surface path of the finished engraving to polish, thereby improving the polishing efficiency, and there is no need to replace the polishing wheel, and the distance can be directly adjusted.

[0027] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the adjusting member 5 includes an annular groove 9, which is opened on the side of the mounting plate 2 away from the polishing machine body 1, a magnetic ring 10 is fixedly installed in the annular groove 9, and an inner gear ring 11 is rotatably installed on the side of the magnetic ring 10.

[0028] In this embodiment, the annular groove 9 is embedded with a magnetic ring 10, so that the magnetic ring 10 limits the movement of the inner gear ring 11, thereby ensuring that the inner gear ring 11 will not be detached due to the driving of the polishing body 1, and facilitating positioning after adjusting the distance between the fixed disk 4 and the sliding disk 6.

[0029] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the mounting plate 2 is located on one side of the inner gear ring 11 and is rotatably mounted with two gear rods 12 , the ends of the two gear rods 12 are fixedly connected with threaded rods 13 , and the threaded rods 13 pass through the sliding plate 6 and are threadedly connected to the sliding plate 6 .

[0030] In this embodiment, when adjusting the spacing between the fixed disk 4 and the sliding disk 6, the inner gear ring 11 is rotated forcefully, so that the inner gear ring 11 drives the rotation of the two gear rods 12, and then drives the rotation of the two threaded rods 13. The sliding disk 6 is meshed with the threaded rods 13, and the synchronous rotation of the two threaded rods 13 drives the sliding disk 6 to slide, thereby achieving the effect of adjusting the spacing.

[0031] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the retractable member 8 includes a plurality of rectangular grooves 14, and the rectangular grooves 14 are opened on the inner peripheral wall of the sliding disk 6. A reeling rod 15 is rotatably installed between the two side walls of the rectangular groove 14. The polishing cloth 7 extends into the corresponding rectangular groove 14 and is wound around the reeling rod 15. A transmission member 16 is provided on the reeling rod 15.

[0032] In this embodiment, the rectangular groove 14 is used to install the winding rod 15, so that the excess part of the polishing cloth 7 is wound on the winding rod 15. As the sliding disk 6 moves, the winding rod 15 is driven to rotate through the transmission member 16, and then the polishing cloth 7 is wound or unwound, while ensuring that the polishing cloth 7 is in a straight state, which is convenient for polishing the engraved products with different curvatures or radii, thereby improving the polishing efficiency.

[0033] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the transmission member 16 includes two transmission gears 17, and the two transmission gears 17 are respectively fixedly mounted on the two ends of the winding rod 15. A transmission rod 18 is rotatably mounted in the rectangular groove 14 below the winding rod 15, and transmission tooth grooves 19 are formed on the outer peripheral walls at both ends of the transmission rod 18, and the transmission tooth grooves 19 are meshed with the corresponding transmission gears 17.

[0034] In this embodiment, when the adjusting member 5 drives the sliding disk 6 to move, it will drive the movement of the transmission rod 18, and then drive the rotation of the transmission gear 17 through the movement of the set transmission tooth groove 19. When the distance between the sliding disk 6 and the fixed disk 4 increases, the reel will be unwound, and when the distance between the two decreases, the reel will be reeled in, thereby ensuring that the arc surface position of different curvatures of the finished engraving product can be accurately polished.

[0035] In a further preferred embodiment of the present invention, Figure 1-3 As shown, a driving rack 20 is installed on the middle peripheral wall of the transmission rod 18, and a limiting tooth groove 21 is opened on the peripheral wall of the support rod 3 at the driving rack 20, and the driving rack 20 is meshed with the transmission tooth groove 19.

[0036] In this embodiment, the driving rack 20 is used to engage with the upper limit tooth groove 21 on the support rod 3. When the sliding disk 6 moves, the transmission rod 18 equipped with the driving rack 20 will be driven to rotate through the set limit tooth groove 21. When the transmission rod 18 rotates, the two transmission gears 17 will be driven to rotate through the set transmission tooth groove 19, thereby achieving the effect of winding up the polishing cloth 7 or unwinding the polishing cloth 7.
