Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0027] like Figures 1-5 As shown, a dental prosthesis carving clamp according to one embodiment of the present invention includes a body mechanism 1, an adjustment mechanism 2, and a clamping mechanism 3. The body mechanism 1 includes a base 11 and a mounting plate 12 fixedly connected to the base 11; the adjustment mechanism 2 includes an angle adjustment component and a translation adjustment component. The angle adjustment component includes an arc-shaped slide rail 21 formed on the arc-shaped corner of the mounting plate 12 and a first slider 22 slidably connected within the arc-shaped slide rail 21. The translation adjustment component includes a first mounting block 26 fixedly connected to the outer wall of the first slider 22 and a second mounting block 210 slidably connected to the first mounting block 26, the first mounting block 26 and the second mounting block 210 being arranged perpendicular to each other; the clamping mechanism 3 includes a third mounting block 31 slidably connected to the second mounting block 210, a pair of clamping plates 34 slidably connected to the third mounting block 31, and a clamping adjustment component. The clamping adjustment component is used to drive the pair of clamping plates 34 to clamp and fix the dental prosthesis.

[0028] When using this dental prosthesis carving fixture, the dental prosthesis model is first placed between a pair of clamping plates 34. The spacing between the clamping plates 34 is adjusted using the clamping adjustment component to stably clamp and fix the dental prosthesis model. Then, according to the carving requirements, the angle and position of the fixed dental prosthesis are adjusted sequentially or simultaneously. When the dental prosthesis needs angle adjustment, the first slider 22 is slid within the arc-shaped slide rail 21, and the angle of the first slider 22 is adjusted by the guide of the arc-shaped slide rail 21. This, in turn, drives the first mounting block 26, the second mounting block 210, and the third mounting block 31 to adjust their angles simultaneously, thereby achieving the adjustment of the dental prosthesis angle. When the dental prosthesis needs position adjustment, the second mounting block 210 is slid on the first mounting block 26, and the third mounting block 31 is slid on the second mounting block 210, to achieve translation of the dental prosthesis in the XY direction. Once the adjustments are complete, the technician can begin carving the model in its optimal position. After completing the operation at one angle, the next adjustment can be made quickly without disassembling the model, greatly improving work efficiency and processing quality.

[0029] Preferably, the angle of the arc-shaped slide rail 21 on the arc-shaped corner of the mounting plate 12 is set so that the first slider 22 can rotate from 0 to 90 degrees within the arc-shaped slide rail 21, so as to realize the angle adjustment of the arc-shaped slide rail 21 from horizontal to vertical direction.

[0030] like Figure 4 and Figure 5 As shown, the angle adjustment assembly also includes a limiting component, which includes an arc-shaped guide rail 23 located on the front sidewall of the mounting plate 12 at the position of the arc-shaped slide rail 21 and along the arc-shaped surface of the arc-shaped slide rail 21, and a locking screw 24 fixedly connected to the front sidewall of the first slider 22.

[0031] like Figure 4 and Figure 5As shown, the end of the locking screw 24 furthest from the first slider 22 passes through the arc-shaped guide rail 23 and is positioned on the outside of the arc-shaped guide rail 23. A wing nut 25 is threadedly connected to the end of the locking screw 24 positioned on the outside of the arc-shaped guide rail 23. The wing nut 25 abuts against the front sidewall of the mounting plate 12, and an anti-slip layer is provided on the side of the wing nut 25 that abuts against the mounting plate 12. When the first slider 22 slides within the arc-shaped guide rail 21, it can drive the locking screw 24 to slide within the arc-shaped guide rail 23. After the first slider 22 completes the angle adjustment required for denture carving, the wing nut 25 is tightened against the mounting plate 12 by rotation. This tightening of the wing nut 25 restricts the sliding of the first slider 22 within the arc-shaped guide rail 21, ensuring that the position of the first slider 22 is fixed after denture angle adjustment, preventing movement during denture carving after angle adjustment. Meanwhile, when the first slider 22 rotates, the wing nut 25 only needs to be loosened, making the locking and loosening operation of the first slider 22 convenient.

[0032] like Figure 4 and Figure 5 As shown, the translation component also includes a first linear slide rail 27 extending along the length of the first mounting block 26, a second slider 28 slidably connected within the first linear slide rail 27, and a first lead screw 29 extending through and rotatably mounted along the length of the first mounting block 26.

[0033] like Figure 4 and Figure 5 As shown, the first lead screw 29 is threaded through to the second slider 28, and the second mounting block 210 is fixedly connected to the second slider 28 on the side wall of one end of the outer side of the first linear slide rail 27. When the first lead screw 29 is rotated, the second slider 28 can be driven to move linearly along the first linear slide rail 27, so that the second mounting block 210 can be moved linearly through the second slider 28.

[0034] like Figure 4 and Figure 5 As shown, the translation component also includes a second linear slide rail 211 extending along the length of the second mounting block 210, a third slider 212 slidably connected within the second linear slide rail 211, and a second lead screw 213 extending through and rotatably mounted along the length of the second mounting block 210.

[0035] like Figure 4 and Figure 5 As shown, the second lead screw 213 is threaded through to the third slider 212, and the third mounting block 31 is fixedly connected to the side wall of the third slider 212, which is located on the outer side of the first linear slide rail 27. When the second lead screw 213 is rotated, the third slider 212 can be driven to move linearly on the second linear slide rail 211, so that the third mounting block 31 can be driven to move linearly through the third slider 212.

[0036] like Figure 4 and Figure 5 As shown, the clamping and adjusting assembly includes a third linear slide rail 32 extending along the length of the third mounting block 31, a pair of fourth sliders 33 slidably connected within the third linear slide rail 32, and a bidirectional lead screw 36 extending through and rotatably mounted along the length of the third mounting block 31.

[0037] like Figure 4 and Figure 5 As shown, a pair of fourth sliders 33 are threaded onto the positive and negative threads of the bidirectional lead screw 36, respectively. A pair of clamps 34 are fixedly connected to the sidewalls of the pair of fourth sliders 33 located on the outer side of the third linear slide rail 32. Protective pads 35 are provided on the opposite sidewalls of the pair of clamps 34. When the bidirectional lead screw 36 is rotated, the positive and negative threads of the bidirectional lead screw 36 drive the pair of fourth sliders 33 to move closer to or further away from each other within the third linear slide rail 32, so that the pair of clamps 34 can move closer to or further away from each other, thereby clamping and releasing the denture through the pair of clamps 34. At the same time, the clamps 34 can be installed in a detachable manner, so that the clamps 34 can be replaced according to the structure of the denture model, so as to better fit the denture model and achieve efficient and stable clamping of the denture model. The protective pads 35 are made of flexible anti-slip material, so that the protective pads can improve the stability of the denture clamping while avoiding damage to the denture surface, and can also buffer the force during denture carving.

[0038] Preferably, the rotation of the first lead screw 29 drives the second slider 28 to move, thereby moving the second mounting block 210; the rotation of the second lead screw 213 drives the third slider 212 to move, thereby moving the third mounting block 31; and the rotation of the bidirectional lead screw 36 drives a pair of fourth sliders 33 to move, thereby moving a pair of clamping plates 34. This enables rapid clamping of the denture and translation of the denture in the XY direction. The threaded drive allows for precise adjustment of the translation distance without the need for additional limiting components, resulting in a simple structure and good practicality of the device.

[0039] In use, the denture model is first placed between a pair of clamps 34. Rotating the bidirectional lead screw 36 drives a pair of fourth sliders 33 closer together, adjusting the distance between the clamps 34. This provides stable clamping and fixing of the denture model. Then, according to the carving requirements, the angle and position of the fixed, carved denture are adjusted sequentially or simultaneously. When the denture requires angle adjustment, loosening the wing nut 25 pushes the first slider 22 to slide within the arc-shaped slide rail 21. The arc-shaped slide rail 21 guides the adjustment of the first slider 22's angle, which in turn drives the first mounting block 26, the second mounting block 210, and the third mounting block 31 to adjust their angles simultaneously, thus achieving denture angle adjustment. After angle adjustment, tightening the wing nut 25 restricts the sliding of the first slider 22, ensuring denture stability. When the denture needs position adjustment, rotating the first lead screw 29 drives the second slider 28 to move, which in turn moves the second mounting block 210. The second mounting block 210 then moves the denture fixed to the third mounting block 31 and clamp 34, causing translation. Rotating the second lead screw 213 drives the third slider 212 to move, which in turn moves the denture fixed to the third mounting block 31 and clamp 34, causing translation. This allows for translation of the denture in the X and Y directions by rotating the first lead screw 29 and the second lead screw 213 respectively. After adjustment, the technician can then perform carving on the model in its optimal position. After completing one angle, the next adjustment can be made quickly without disassembling the model, greatly improving work efficiency and processing quality.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of this disclosure is defined by the appended claims rather than the foregoing description.
