Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of denture processing, in particular to a cutting device for 3D printed dentures. BACKGROUND

[0002] 3D printing is usually realized by using a digital technology material printer, and is often used in mold manufacturing, industrial design and other fields to manufacture models, and is gradually used for direct manufacturing of some products. The denture printed by using 3D technology has a high degree of fit with the repaired tooth and gum position, and has been widely applied by denture manufacturing enterprises. At present, after the denture is manufactured by metal 3D printing, the root of the denture is fixed on a base plate which is integrally formed with the denture.

[0003] In the related art, the cutting device includes a placing platform, a fixing clamp and a cutting device. The processing personnel places the base plate on the placing platform, the fixing clamp clamps the base plate, and then the cutting device starts to cut the denture fixed on the base plate to separate the denture from the base plate. Since the connection between the denture and the base plate is usually an irregular arc surface, the cutting position of the denture is polished after the denture is separated from the base plate.

[0004] In view of the above related art, the inventors believe that the following defects exist: Since the connection between the denture and the base plate is usually an irregular arc surface, when the cutting device is working, the denture is more likely to be tilted and fallen during the separation process, which is easy to cause the cutting device to cut the denture itself, causing damage to the denture product, and even causing the product to be scrapped.

[0044] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0045] This application discloses a cutting device for 3D printed dentures, such as... Figure 1 As shown, the assembly includes a processing platform 1, a feeding component 2, a first clamping component 4, a second clamping component 5, a drive component 3, and a cutting component 9. The feeding component 2 is used for feeding materials, the first clamping component 4 is used to clamp and fix the substrate 8, the second clamping component 5 is used to clamp and fix the denture, and the drive component 3 is used to drive the first clamping component 4 and the second clamping component 5 to move closer to or further away from each other. After the first clamping component 4 and the second clamping component 5 are in place, the cutting component 9 starts to cut the denture. After cutting, the drive component 3 drives the first clamping component 4 and the second clamping component 5 to move further away from each other, thereby separating the substrate 8 from the denture.

[0046] like Figure 1 As shown, a loading groove 13 is provided on the circumferential direction of the processing platform 1. The loading assembly 2 includes a loading block 21, which has a built-in drive source (not shown in the figure). A loading magnetic block one is fixedly connected to the loading block 21, and a loading magnetic block two is fixedly connected to the circumferential surface of the substrate 8. The processing platform 1 is provided with a loading area 11 and a cutting processing area 12, which are located at both ends of the processing platform 1 along the same diameter direction. The processing personnel place the substrate 8 on the loading block 21 through the loading area 11, so that the loading magnetic block two and the loading magnetic block one attract each other. Through magnetic attraction, the connection between the loading block 21, the substrate 8, and the denture is realized, which facilitates the subsequent movement of the loading block 21 carrying the substrate 8 and the denture to the corresponding cutting processing area 12.

[0047] like Figure 2As shown, the drive assembly 3 includes a drive shaft 31, a take-up reel 32, and a drive rope 321. The drive shaft 31 is rotatably connected to the processing platform 1, and its axis is parallel to the diameter of the connecting line between the loading area 11 and the cutting area 12. The take-up reel 32 is fixedly connected to one end of the drive shaft 31 near the loading area 11, and a coil spring is fixedly connected to the take-up reel 32. One end of the drive rope 321 is connected to the take-up reel 32 via the coil spring, and the other end of the drive rope 321 is fixedly connected to a pull buckle 33. A drive movement groove 17 is provided inside the processing platform 1, and the drive movement groove 17 communicates with the loading groove 13. A first fixed magnetic block is fixedly connected to the groove wall of the drive movement groove 17 located below the loading area 11, and a second fixed magnetic block is fixedly connected to the pull buckle 33. In the initial state, the second fixed magnetic block and the first fixed magnetic block attract each other, temporarily fixing the pull buckle 33, and the relative position between them and the groove wall of the drive movement groove 17 is stable. A pull hook 22 is fixedly connected to the feeding block 21, and the end of the pull hook 22 away from the feeding block 21 extends into the drive moving groove 17. When the feeding block 21 moves along the feeding groove 13 to the feeding position 11, the pull hook 22 and the pull buckle 33 engage with each other. As the feeding block 21 continues to move along the feeding groove 13, the pull hook 22 drives the pull buckle 33 to move along the drive moving groove 17. The pull buckle 33 drives the drive rope to unwind and drives the drive shaft 31 to rotate.

[0048] like Figure 3 and 4 As shown, the first clamping assembly 4 includes a first clamping block 41 and a clamping plate 42. A first threaded section 311 is integrally formed on one end of the drive shaft 31 near the cutting area 12. A first support frame 14 is fixedly connected to the side of the processing platform 1 facing the first threaded section 311. The first clamping block 41 is threadedly connected to the first threaded section 311 and slides along the first support frame 14. Two clamping plates 42 are provided, slidably connected to the first clamping block 41, and the sliding direction of the clamping plates 42 is perpendicular to the sliding direction of the first clamping block 41. The two clamping plates 42 move synchronously closer to or further away from each other. The first clamping block 41 has a built-in drive source (not shown in the figure) for driving the movement of the clamping plates 42.

[0049] like Figure 1 and 4As shown, the second clamping assembly 5 includes a second clamping block 51, an inner support ring 52, and an outer abutment ring 53. A second threaded section 312 is integrally formed on the drive shaft 31, and the threads of the first threaded section 311 and the second threaded section 312 have opposite directions. A second support frame 15 is fixedly connected to the processing platform 1 on the side opposite to the first support frame 14. The second clamping block 51 is threadedly connected to the second threaded section 312 and slides along the second support frame 15. The inner support ring 52 and the outer abutment ring 53 are fixedly connected to the second clamping block 51, and their relative positions are stable. Both the inner support ring 52 and the outer abutment ring 53 are made of rubber, and a clamping space 531 is formed between them. The clamping space 531 is for placing the denture, and the inner support ring 52 and the outer abutment ring 53 clamp the denture.

[0050] like Figure 5 and 6 As shown, it also includes a limiting component 7, which includes a wedge 71 and a support spring 72. A transition section 18 is provided on the worktable, located in the middle between the loading section 11 and the cutting section 12. A limiting groove 75 is formed on one side wall of the drive moving groove 17. The wedge 71 is slidably connected to the transition section 18 and located on the groove wall of the drive moving groove 17. One end of the support spring 72 is fixedly connected to the wedge 71, and the other end of the support spring 72 away from the wedge 71 is fixedly connected to the bottom of the limiting groove 75. A limiting space 76 is left between the groove wall of the limiting groove 75 and the wedge 71, and the limiting space 76 is used for the pull buckle 33 to engage.

[0051] like Figure 6 As shown, when the loading block 21 moves along the loading groove 13 to the loading point 11, the pull hook 22 engages with the pull buckle 33. The operator places the substrate 8 on the loading block 21, and the loading block 21 continues to move along the loading groove 13, simultaneously carrying the pull buckle 33 along the drive moving groove 17. During the movement, the pull buckle 33 drives the drive shaft 31 to rotate, and the rotation of the drive shaft 31 enables the first clamping block 41 and the second clamping block 51 to move away from each other synchronously. When the loading block 21 moves to the transition point 18, the pull buckle 33 abuts against the wedge surface of the wedge block 71 under the action of the pull hook 22, and presses against the support spring 72. Subsequently, the pull buckle 33 enters the limiting space 76, and the wedge block 71 returns to its original position under the elastic force of the support spring 72. The limiting space 76 limits the pull buckle 33.

[0052] like Figure 2As shown, to facilitate the separation of the pull hook 22 from the pull latch 33, the pull hook 22 includes a connecting rod 221 and a hooking rod 222. One end of the connecting rod 221 is fixedly connected to the loading block 21, and the hooking rod 222 is hinged to the end of the connecting rod 221 away from the loading block 21. When the pull latch 33 is stopped, the loading block 21 continues to move. Driven by the loading block 21, the hooking rod 222 rotates relative to the connecting rod 221 and separates from the pull latch 33. At this time, the drive rope 321 is stationary, the drive shaft 31 also stops rotating, and the first clamping block 41 and the second clamping block 51 move into place. The loading block 21 continues to carry the substrate 8 until it reaches the cutting processing area 12.

[0053] like Figure 6 As shown, the limiting assembly 7 also includes a connecting rod 73 and a protrusion (not shown in the figure). The connecting rod 73 is rotatably connected to the processing platform 1. One end of the connecting rod 73 is fixedly connected to the wedge block 71, and the other end is fixedly connected to the protrusion. The protrusion is located at the cutting processing area 12 and extends into the loading groove 13. When the loading block 21 moves to the cutting processing area 12, it presses against the protrusion. The protrusion drives the connecting rod 73 to rotate, and the connecting rod 73 drives the wedge block 71 to move into the limiting groove 75, making room for the pull buckle 33 to move back. After the limiting is released, under the action of the coil spring, the pull buckle 33 automatically moves back along the drive moving groove 17 and drives the drive shaft 31 to rotate in the opposite direction.

[0054] The drive shaft 31 rotates, driving the first clamping block 41 and the second clamping block 51 to move closer to each other synchronously. When the first clamping block 41 and the second clamping block 51 are in place, the inner support ring 52 and the outer abutment ring 53 clamp the denture. The clamping plate 42 is located on both sides of the substrate 8, which facilitates the synchronous clamping of the substrate 8 and the denture.

[0055] like Figure 4 As shown, it also includes an auxiliary component 6, which includes an air pump 61, an inner support bladder 62, and an outer abutment bladder 63. The air pump 61 is fixedly connected to the second support frame 15. The inner support bladder 62 is fixedly connected to the side of the inner support ring 52 opposite to the outer abutment ring 53. The outer abutment bladder 63 is fixedly connected to the side of the outer abutment ring 53 opposite to the inner support ring 52. The air pump 61, the inner support bladder 62, and the outer abutment bladder 63 are connected. When the first clamping block 41 and the second clamping block 51 are moved into place, the air pump 61 is activated. The air pump 61 simultaneously pressurizes and inflates the inner support bladder 62 and the outer abutment bladder 63, so that the inner support bladder 62 further supports the inner support ring 52, and the outer abutment bladder 63 further presses against the outer abutment ring 53, which helps to improve the stability of the denture clamping. At the same time as the air pump 61 is activated, the two clamping plates 42 move closer to each other and clamp and fix the base plate 8, which helps to improve the stability of the relative position between the denture and the base plate 8 during the cutting process of the cutting part 9. It also facilitates the separation of the loading block 21 from the substrate 8, and the loading block 21 can continue to move along the loading groove 13.

[0056] like Figure 1 As shown, while the loading block 21 continues to move, the cutting component 9 completes the cutting and separation of the substrate 8 and the denture. When the loading block 21 moves to the loading position 11, the pulling hook 22 engages with the pulling buckle 33 again. The loading block 21 drives the pulling buckle 33 to move, driving the drive shaft 31 to rotate, realizing the movement of the first clamping block 41 and the second clamping block 51 away from each other, thereby achieving the separation of the cut denture from the substrate 8. After the first clamping block 41 and the second clamping block 51 move into position, the inner support bladder 62 and the outer abutment bladder 63 contract, releasing the pressure on the inner support ring 52 and the outer abutment ring 53, making it easier for the denture to be removed from the clamping space 531. To improve the smoothness of denture removal from the clamping space 531, a push plate 54 is fixedly connected to the second support frame 15. When the second clamping block 51 moves away from the cutting piece 9 and into position, the push plate 54 pushes the denture, further separating the denture from the inner support ring 52 and the outer abutment ring 53. For easy collection, a receiving box 16 is provided below both the first support frame 14 and the second support frame 15. This process is repeated to achieve the cutting and separation between the substrate 8 and the denture, and to improve the stability of the relative position between the denture and the substrate 8 in the process.

[0057] The implementation principle of a cutting device for 3D printed dentures according to an embodiment of this application is as follows:

[0058] When the loading block 21 moves along the loading trough 13 to the loading point 11, the pull hook 22 and the pull buckle 33 engage with each other. As the loading block 21 continues to move along the loading trough 13, the pull hook 22 drives the pull buckle 33 to move along the drive moving groove 17. The pull buckle 33 drives the drive rope to unwind and rotates the drive shaft 31. The rotation of the drive shaft 31 enables the first clamping block 41 and the second clamping block 51 to move away from each other synchronously. When the loading block 21 moves to the transition point 18, the pull buckle 33 is restricted from moving.

[0059] When the loading block 21 moves to the cutting area 12, it presses against the protruding block. The protruding block drives the connecting rod 73 to rotate, and the connecting rod 73 drives the wedge block 71 to move into the limiting groove 75, thus releasing the locking buckle 33. The drive shaft 31 rotates, causing the first clamping block 41 and the second clamping block 51 to move synchronously closer to each other, clamping the substrate 8 and the denture. This ensures that the relative position between the substrate 8 and the denture remains stable during the cutting process of the cutting part 9, reducing the probability of denture displacement, minimizing the possibility of cutting damage to the denture itself, and improving the processing quality of the cutting process.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
