Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis processing technology, and in particular to a dental prosthesis carving machine. Background Technology

[0002] Dentures are a restorative method that uses artificially made teeth to replace missing natural teeth. A dental prosthesis carving machine is a new type of carving machine specifically designed to create dentures according to user needs. The working principle of a dental prosthesis carving machine is based on digital scan data of the patient's oral cavity, which is then designed using computer software. The designed model is then transmitted to the carving machine for processing. Following the instructions of the design model, the carving machine uses high-speed rotating cutters to precisely carve and process the denture material, ultimately producing a customized denture that meets the patient's oral needs.

[0003] Most dental prosthesis carving machines on the market require the machine to be stopped and the door opened when the carving tool is damaged or needs to be replaced to complete the carving of dentures of different shapes or materials. The operator then has to manually remove the old tool and install the new one. This manual tool replacement process is cumbersome and time-consuming, reducing overall work efficiency.

[0054] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0055] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

Therefore, they should not be construed as limitations on this utility model.

[0057] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0058] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

The illustrative expressions of the above terms in this specification should not be construed as necessarily referring to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0061] Please see the appendix Figures 1 to 7 This utility model provides a dental prosthesis engraving machine, including: an engraving machine body 1, which has a spindle mechanism mounting cavity 11 and a dental prosthesis processing cavity 12, and a spindle movable groove 13 between the spindle mechanism mounting cavity 11 and the dental prosthesis processing cavity 12; a spindle drive mechanism and a spindle assembly 2 are provided in the spindle mechanism mounting cavity 11, the spindle drive mechanism drives the spindle assembly 2 to move, the spindle assembly 2 extends through the spindle movable groove 13 into the dental prosthesis processing cavity 12, and the spindle assembly 2 is used to install the engraving tool 402 and drive the engraving tool 402 to move; a positioning plate drive mechanism and a dental prosthesis positioning plate 3 are provided in the dental prosthesis processing cavity 12, the positioning plate drive mechanism drives the dental prosthesis positioning plate 3 to move, the dental prosthesis positioning plate 3 is used to place the dental prosthesis and drive the dental prosthesis to rotate, when the positioning plate drive mechanism is started, the positioning plate drive mechanism drives the dental prosthesis positioning plate 3 to rotate around a designated axis through a worm gear transmission mechanism.

[0062] Furthermore, the denture processing cavity 12 is also equipped with a tool magazine 4. The tool magazine 4 has several insertion holes 401 for inserting tools 402. The wall of the insertion hole 401 is at least partially made of elastic material. When the tool 402 is inserted into the insertion hole 401, the elastic material and the tool 402 are in an interference fit. Understandably, in the denture carving machine, the tool magazine 4 allows for quick tool replacement of the tool 402, avoiding the time wasted by frequent tool replacements during production, thereby improving production efficiency. Specifically, the tool magazine 4 can store various types of tools 402 to meet different processing needs. For example, in the denture carving process, tools 402 of different shapes, sizes, and materials may be needed to handle different carving tasks. The existence of the tool magazine 4 allows the dentist to quickly select the appropriate tool 402 as needed, thus ensuring processing quality.

[0063] In this embodiment, the elastic material can be a rubber-based material, such as styrene-butadiene rubber, cis-butadiene rubber, neoprene rubber, etc.; the elastic material can also be a thermoplastic elastomer material, such as SBS, SEBS, TPV, TPU, etc.; the elastic material can also be silicone. It should be noted that this is only a small list of elastic materials that can be used, and it does not limit the types of elastic materials that can be selected. In other embodiments, other elastic materials with the same elasticity as the aforementioned rubber, thermoplastic elastomer, and silicone materials can also be selected. The elastic material can cover the entire wall of the insert hole 401, or it can only cover a portion of the wall of the insert hole 401. When the cutter 402 is inserted into the insert hole 401, the cutter 402 will squeeze open the elastic material portion of the wall of the insert hole 401. Due to the elastic deformation capability and rebound force inherent in the elastic material itself, it will provide a reverse squeezing elastic force to the cutter 402, so that the cutter 402 is stably inserted into the insert hole 401. It should be emphasized that this embodiment utilizes the properties of the elastic material used to manufacture the tool magazine 4 to achieve the purpose of stably positioning the inserted tool 402, reducing the space that needs to be reserved in the tool magazine 4 for the mechanical clamping structure during the design stage, thereby reducing the overall design volume of the tool magazine 4, which is more in line with the requirements of modern dental prosthesis carving for efficient, compact and precision machining.

[0064] Furthermore, the tool magazine 4 includes a tool holder 41 and a tool inserting block 42. The tool inserting block 42 is disposed on the tool holder 41. The tool inserting hole 401 consists of a first inserting hole 421 formed on the tool inserting block 42 and a second inserting hole 411 formed on the tool holder 41. The first inserting hole 421 and the second inserting hole 411 are coaxial. Both the tool holder 41 and the tool inserting block 42 can be made of elastic material to ensure that the first inserting hole 421 and / or the second inserting hole 411 provide effective and stable positioning for the inserted tool 402.

[0065] In the first embodiment, the insert block 42 is made of an elastic material. When the cutter 402 is inserted into the insert hole 401, the first insertion hole 421 and the cutter 402 are in an interference fit. In this embodiment, the insert block 42 is made of an elastic material, while the insert holder 41 is made of another material. Therefore, when the cutter 402 is inserted into the insert hole 401, it will be subjected to the action of the elastic material in the first insertion hole 421, resulting in an interference fit with the first insertion hole 421. However, it will not be subjected to the action of the elastic material in the second insertion hole 411. It should be considered that the interference fit between the elastic material and the cutter 402 may be damaged during repeated insertion and removal of the cutter 402. Therefore, in this embodiment, only the insert block 42 is made of an elastic material, which facilitates later maintenance. When the insert block 42 is damaged, a new insert block 42 can be directly replaced and installed on the insert holder 41.

[0066] In the second embodiment, the insert holder 41 is made of an elastic material. When the cutter 402 is inserted into the insert hole 401, the second insert hole 411 and the cutter 402 are in an interference fit. In this embodiment, the insert holder 41 is made of an elastic material, while the insert block 42 is made of another material. Thus, when the cutter 402 is inserted into the insert hole 401, it is not affected by the elastic material in the first insert hole 421, but is affected by the elastic material in the second insert hole 411, resulting in an interference fit. It should be considered that the interference fit between the elastic material and the cutter 402 may be damaged during repeated insertion and removal of the cutter 402. Therefore, in this embodiment, only the insert holder 41 is made of an elastic material, which makes it easier for later maintenance. When the insert holder 41 is damaged, a new insert holder 41 can be directly replaced and assembled with the original insert block 42.

[0067] In the third embodiment, both the inserter base 41 and the inserter block 42 are made of elastic materials. When the cutter 402 is inserted into the inserter hole 401, both the first insertion hole 421 and the second insertion hole 411 are interference-fitted with the cutter 402. In this embodiment, the use of elastic materials for both the inserter base 41 and the inserter block 42 increases the contact area between the elastic material and the inserted cutter 402, thus enhancing the stability of the cutter 402 within the inserter hole 401.

[0068] Furthermore, the inserter base 41 is provided with a mounting groove 412 on the side facing the insertion of the cutter 402, and the second insertion hole 411 is opened from the bottom of the mounting groove 412 along the insertion direction of the cutter 402; the shape of the inserter block 42 matches the mounting groove 412, the inserter block 42 is embedded in the mounting groove 412, and the first insertion hole 421 on the inserter block 42 and the second insertion hole 411 on the inserter base 41 correspond one-to-one along the insertion direction of the cutter 402.

[0069] Furthermore, to enhance the stability of the insert block 42 mounted on the insert holder 41, the tool magazine 4 also includes a pressure plate 43 connected to the insert holder 41, with the insert block 42 clamped between the pressure plate 43 and the insert holder 41. The pressure plate 43 has a window 431, through which the insertion port of the first insertion hole 421 is exposed. Specifically, a first step portion 422 is provided on the side of the insert block 42 away from the insert holder 41, and a second step portion 432 is provided on the inner periphery of the window 431 facing the insert block 42. The second step portion 432 presses against the first step portion 422, thereby tightly pressing the insert block 42 between the pressure plate 43 and the insert holder 41, preventing displacement of the insert block 42 during use, and ensuring precise alignment of the first insertion hole 421 and the second insertion hole 411. Furthermore, the pressure plate 43 is detachably fixed to the inserter seat 41 by screws. When it is necessary to maintain the inserter block 42 and / or the inserter seat 41, the pressure plate 43 can be removed to take the inserter block 42 out of the mounting slot 412 of the inserter seat 41, which is convenient and quick.

[0070] Furthermore, the spindle drive mechanism includes at least one of a first spindle drive mechanism, a second spindle drive mechanism, and a third spindle drive mechanism; wherein, the first spindle drive mechanism is used to drive the spindle assembly to move in a first direction; the second spindle drive mechanism is used to drive the spindle assembly to move in a second direction; and the third spindle drive mechanism is used to drive the spindle assembly to move in a third direction; the first direction, the second direction, and the third direction are different from each other. Preferably, the first direction, the second direction, and the third direction are the X-axis direction, the Y-axis direction, and the Z-axis direction, respectively. It can be understood that the spindle assembly 2 in the denture engraving machine is a component used to carry the engraving cutter, and the spindle drive mechanism is used to drive the spindle assembly 2 to move in the horizontal or vertical direction, so as to control the engraving cutter carried by the spindle assembly 2 to perform complex engraving actions on the denture.

[0071] Specifically, please refer to Figures 8 to 13 The first spindle drive mechanism includes a first mounting base 216, and a first spindle motor 21, a first lead screw and slider assembly, and a first synchronous pulley assembly mounted on the first mounting base 216. The output shaft of the first spindle motor 21 is connected to the drive end of the first lead screw and slider assembly via the first synchronous pulley assembly. The first spindle motor 21 and the first lead screw and slider assembly are located on the same side of the first synchronous pulley assembly. In this embodiment, since the output shaft of the first spindle motor and the drive end of the first lead screw and slider assembly are connected via the first synchronous pulley assembly, it is not necessary to reserve space for installing the first spindle motor on one side of the drive end of the first lead screw and slider assembly. Correspondingly, in a dental prosthesis engraving machine, the length direction of the first lead screw and slider assembly can be the front-back direction, the left-right direction, or the vertical direction of the dental prosthesis engraving machine. Therefore, the setting of this embodiment can effectively reduce the thickness of the spindle mechanism mounting cavity 11 in the front-back direction, the width in the left-right direction, or the height in the vertical direction.

[0072] Specifically, the first lead screw and slider assembly includes a first lead screw 211, the first synchronous belt pulley assembly includes a first driving pulley 212, a first driven pulley 213 and a first synchronous belt 214, the first spindle motor 21 and the first lead screw 211 are both connected to the first mounting base 216, the output shaft of the first spindle motor 21 is connected to the first driving pulley 212, one end of the first lead screw 211 is connected to the first driven pulley 213, the first synchronous belt 214 is wound around the first driving pulley 212 and the first driven pulley 213, the first driving pulley 212, the first driven pulley 213 and the first synchronous belt 214 are located in the same vertical plane, and the first spindle motor 21 and the first lead screw 211 are located on the same side of the first driving pulley 212 and the first driven pulley 213.

[0073] Optionally, the spindle mechanism mounting cavity 11 is provided with a first slide rail 217 and a first slide plate 218. The first slide rail 217 is arranged along the axial direction of the first lead screw 211, and the first slide plate 218 is slidably connected to the first slide rail 217. A first transmission nut 215 is screwed onto the first lead screw 211, and the first slide plate 218 is fixed to the first transmission nut 215. The spindle assembly 2 is mounted on the first slide plate 218 and moves synchronously with the first slide plate 218. When the first spindle motor 21 starts, the first lead screw 211 rotates, causing the first transmission nut 215 to move. The first transmission nut 215 causes the first slide plate 218 to move along the axial direction of the first lead screw 211 on the first slide rail 217, and then the first slide plate 218 causes the spindle assembly 2 to move along the axial direction of the first lead screw 211. Specifically, the axial direction of the first lead screw 211 is the X-axis direction, which corresponds to the length direction of the dental prosthesis engraving machine. Preferably, the first spindle motor 21 is located vertically above the first lead screw 211. It is understood that mounting the first spindle motor 21 vertically above the first lead screw 211 makes full use of the height space within the dental prosthesis carving machine. Generally, the height space required for the transmission mechanism (i.e., the third spindle motor 23 and the third lead screw 231 mentioned later) used to drive the spindle assembly 2 to move vertically in the dental prosthesis carving machine is higher than the height space required for the first lead screw 211 and the first spindle motor 21. Mounting the first spindle motor 21 above the first lead screw 211 fully utilizes this height difference and makes full use of the existing height space within the dental prosthesis carving machine.

[0074] Furthermore, the second spindle drive mechanism includes a second spindle motor 22, a second lead screw 221, a second driving wheel, a second driven wheel, and a second synchronous belt. The output shaft of the second spindle motor 22 is connected to the second driving wheel, one end of the second lead screw 221 is connected to the second driven wheel, and the second synchronous belt is wound around the second driving wheel and the second driven wheel. The second driving wheel, the second driven wheel, and the second synchronous belt are located in the same vertical plane, and the second spindle motor 22 and the second lead screw 221 are located on the same side of the second driving wheel and the second driven wheel.

[0075] Optionally, a second mounting base is provided on the first slide plate 218, and the second spindle motor 22 and the second lead screw 221 are both mounted on the second mounting base. Optionally, a second slide rail 222 and a second slide plate 223 are also provided on the first slide plate 218. The second slide rail 222 is arranged along the axial direction of the second lead screw 221, and the second slide plate 223 is slidably connected to the second slide rail 222. A second transmission nut is screwed onto the second lead screw 221, and the second slide plate 223 is fixed to the second transmission nut. The spindle assembly 2 is mounted on the second slide plate 223 and moves synchronously with the second slide plate 223. When the second spindle motor 22 is started, the second lead screw 221 rotates, causing the second transmission nut to move. The second transmission nut causes the second slide plate 223 to move along the axial direction of the second lead screw 221 on the second slide rail 222, and then the second slide plate 223 causes the spindle assembly 2 to move along the axial direction of the second lead screw 221. Optionally, the axis of the second lead screw 221 is the Y-axis direction, which corresponds to the width direction of the dental prosthesis carving machine.

[0076] Alternatively, in another embodiment, the transmission connection between the second spindle motor 22 and the second lead screw 221 can be achieved without using the second driving wheel, the second driven wheel, and the second synchronous belt described above. Instead, the second lead screw 221 can be directly coaxially connected to the output shaft of the second spindle motor 22. This is because the area of ​​the first sliding plate 218 must be smaller than the bottom cavity wall area of ​​the spindle mechanism mounting cavity 11. Only in this way can the first sliding plate 218 slide in the spindle mechanism mounting cavity 11. Thus, the second lead screw 221 located on the first sliding plate 218 can effectively utilize the space difference between the first sliding plate 218 and the side wall of the spindle mechanism mounting cavity 11 to install the second spindle motor 22, so that the output shaft of the second spindle motor 22 is directly coaxially connected to the second lead screw 221. However, it should be explained that there is not enough clearance to install the second spindle motor 22 in all scenarios. Therefore, users can choose to install the second spindle motor 22 coaxially on the second lead screw 221, or use the second driving wheel, the second driven wheel, and the second synchronous belt to install the second spindle motor 22 on the side of the second lead screw 221.

[0077] For further details, please refer to Figures 11 to 13 The third spindle drive mechanism includes a third spindle motor 23, a third lead screw 231, a third drive wheel 232, a third driven wheel 233, and a third synchronous belt 234. The output shaft of the third spindle motor 23 is connected to the third drive wheel 232, the upper end of the third lead screw 231 is connected to the third driven wheel 233, and the third synchronous belt 234 is wound around the third drive wheel 232 and the third driven wheel 233. The third drive wheel 232, the third driven wheel 233, and the third synchronous belt 234 are located in the same horizontal plane, and the third spindle motor 23 and the third lead screw 231 are located on the same side of the third drive wheel 232 and the third driven wheel 233.

[0078] Optionally, a third mounting base 236 is provided on the second slide plate 223. The third spindle motor 23 and the third lead screw 231 are both mounted on the third mounting base 236. A third transmission nut 235 is screwed onto the third lead screw 231. The spindle assembly 2 is fixed to the third transmission nut 235. The axial direction of the third lead screw 231 is the Z-axis direction. The axial directions of the first lead screw 211, the second lead screw 221, and the third lead screw 231 together constitute the XYZ axis system for the movement of the spindle assembly 2. When the third spindle motor 23 starts, the rotation of the third lead screw 231 causes the third transmission nut 235 to move, and the third transmission nut 235 causes the spindle assembly 2 to move along the axial direction of the third lead screw 231. Preferably, the output shaft of the third spindle motor 23 faces upward. Since the output shaft of the third spindle motor 23 and the upper end of the third lead screw 231 are both vertically upward and are connected by transmission through the third driving wheel 232, the third driven wheel 233 and the third synchronous belt 234, there is no need to reserve space for installing the third spindle motor 23 in the height direction of the third lead screw 231, which effectively reduces the height of the denture engraving machine.

[0079] For further details, please refer to 18 to Figure 20 The spindle mechanism mounting cavity 11 has a first slide rail 217 and a first movable channel 131 on its bottom wall. The first slide rail 217 is arranged along the X-axis. The spindle mechanism mounting cavity 11 also has a first sliding plate 218, which is slidably connected to the first slide rail 217. The first sliding plate 218 has a second slide rail 222 and a second movable channel 132, which is arranged along the Y-axis. The spindle mechanism mounting cavity 11 also has a second sliding plate 223, which is slidably connected to the second slide rail 222. The second sliding plate 223 has a third movable channel 133. The spindle assembly 2 is arranged along the Z-axis. The main shaft movable groove 13 is slidably connected to the second slide plate 223 and passes through the third movable channel 133, the second movable channel 132, and the first movable channel 131 along the Z-axis. The first movable channel 131, the second movable channel 132, and the third movable channel 133 form the main shaft movable groove 13. When the first slide plate 218 slides along the first slide rail 217, the first slide plate 218 drives the main shaft assembly 2 to move along the X-axis in the first movable channel 131. When the second slide plate 223 slides along the second slide rail 222, the second slide plate 223 drives the main shaft assembly 2 to move along the Y-axis in the second movable channel 132 and the first movable channel 131.

[0080] In this embodiment, through the layered arrangement of the bottom cavity wall of the spindle mechanism mounting cavity 11, the first sliding plate 218, and the second sliding plate 223, the first slide rail 217 on the bottom cavity wall of the spindle mechanism mounting cavity 11 and the first sliding plate 218 are responsible for the sliding of the spindle assembly 2 in the X-axis direction (i.e., the width direction of the denture carving machine). The second sliding plate 223 and the second slide rail 222 on the first sliding plate 218 are responsible for the sliding of the spindle assembly 2 in the Y-axis direction (i.e., the length direction of the denture carving machine). The sliding engagement component between the spindle assembly 2 and the second sliding plate 223 is responsible for the sliding of the spindle assembly 2 in the Z-axis direction (i.e., the height direction of the denture carving machine). This allows the movement of the spindle assembly 2 in each direction to be independently controlled without interference. It is understood that in this embodiment, the precise movement of the spindle assembly 2 in three-dimensional space is achieved through the layered arrangement of the bottom cavity wall of the spindle mechanism mounting cavity 11, the first slide plate 218 and the second slide plate 223, and the sliding connection between them. This makes the mass distribution of the spindle assembly 2 on the first slide plate 218 and the second slide plate 223 more uniform, reduces the bias in one direction, and thus reduces the requirements for the strength of the slide rail. Due to the optimization of the mass distribution of the spindle assembly 2, the first slide rail 217 and the second guide rail in the dental prosthesis engraving machine of this embodiment can use smaller guide rails instead of relying on traditional high-strength large guide rails. This not only reduces the size and weight of the equipment, but also improves the portability and flexibility of the equipment, which is conducive to the miniaturization design of the dental prosthesis engraving machine.

[0081] Optionally, the width of the first movable channel 131 along the X-axis is greater than the width of the second movable channel 132 along the X-axis, and the width of the second movable channel 132 along the Y-axis is greater than the width of the third movable channel 133 along the Y-axis. It can be understood that the greater width of the first movable channel 131 along the X-axis is primarily due to the fact that as the bottom wall of the spindle mechanism mounting cavity 11, the first slide plate 218, and the second slide plate 223 are stacked from bottom to top, the movement range of objects closer to the top layer is limited by the boundary of the lower layer. Therefore, the width of its movable channel can be reduced accordingly to further promote the miniaturization design of the dental prosthesis engraving machine. Similarly, the greater width of the second movable channel 132 along the Y-axis is also to optimize space utilization, reduce unnecessary space waste, and make the entire transmission mechanism more compact.

[0082] Furthermore, two first slide rails 217 are provided on the bottom wall of the spindle mechanism mounting cavity 11, and a first movable channel 131 is opened between the two first slide rails 217. The center of gravity of the first assembly composed of the first slide plate 218, the second slide plate 223, and the spindle assembly 2 is located above the first movable channel 131 between the two first slide rails 217. Two second slide rails 222 are provided on the first slide plate 218, and a second movable channel 132 is opened between the two second slide rails 222. The center of gravity of the second assembly composed of the second slide plate 223 and the spindle assembly 2 is located above the second movable channel 132 between the two second slide rails 222. It can be understood that designing the center of gravity of the first assembly between the two first slide rails 217 can ensure that the first assembly can maintain good stability when moving in the X-axis direction, reducing shaking and errors. The first slide rails 217 can bear the weight more evenly, reducing wear and deformation caused by uneven weight distribution. Therefore, the width of the first slide rail 217 in this embodiment can be appropriately reduced compared to traditional high-strength large guide rails. By designing the center of gravity of the second assembly between the two second slide rails 222, it can be ensured that the second assembly can maintain good stability when moving in the Y-axis direction, reducing swaying and errors. The second slide rails 222 can bear the weight more evenly, reducing wear and deformation caused by uneven weight distribution. Therefore, the width of the second slide rails 222 in this embodiment can be appropriately reduced compared to traditional high-strength large guide rails.

[0083] For further information, please refer to [link / reference]. Figures 11 to 13 The spindle assembly 2 includes a spindle 202 and a spindle clamp 201. The spindle 202 is mounted vertically on the spindle clamp 201. The spindle clamp 201 and the second slide plate 223 are slidably connected along the Z-axis by a sliding engagement assembly. The sliding engagement assembly includes a third lead screw 231, a vertical guide rail 2011, and a vertical slider 2232. The vertical slider 2232 is slidably connected to the vertical guide rail 2011. A third transmission nut 235 is provided on the third lead screw 231. The spindle clamp 201... The vertical guide rail 2011 is fixedly connected to the third transmission nut 235 and is arranged vertically on the outside of the main shaft clamp 201. The vertical slider 2232 is arranged on the second slide plate 223. Two vertical guide rails 2011 are provided, and two rows of vertical sliders 2232 are correspondingly arranged. The central axis of the main shaft 202 is located on the vertical symmetry plane of the two rows of vertical sliders 2232, and the line connecting the central axis of the main shaft 202 and the third lead screw 231 is perpendicular to the vertical symmetry plane of the two rows of vertical sliders 2232. Preferably, in this embodiment, the main shaft 202 is an airless main shaft 202, eliminating the need for the user to add an air source generator.

[0084] In this embodiment, the sliding engagement component provides a stable vertical sliding surface and rotation limit for the spindle clamp 201. The vertical sliding surface is responsible for providing relative sliding between the spindle clamp 201 and the second slide plate 223, while the rotation limit is used to restrict the rotation of the spindle clamp 201, ensuring relative rotation between the third lead screw 231 and the third transmission nut 235. Thus, when the third lead screw 231 rotates, the third transmission nut 235 can drive the spindle clamp 201 to move in the vertical direction. At the same time, the sliding engagement component maintains the stability and accuracy of the spindle clamp 201, effectively reducing vibration and deviation during the lifting process. Furthermore, the arrangement of two vertical guide rails 2011 and two columns of vertical sliders 2232 can distribute the load during the lifting process, making the stress on each component more uniform, thereby improving the overall load-bearing capacity. In addition, the cooperation between the two vertical guide rails 2011 and the two columns of vertical sliders 2232 can ensure that the movement trajectory of the main shaft assembly 2 during the lifting process is more stable and straight, reducing errors caused by deviations in the movement trajectory. During operation, when the third lead screw 231 starts to rotate, the third transmission nut 235 drives the main shaft clamp 201 and the main shaft 202 to move in the vertical direction. The two columns of vertical sliders 2232 slide on the two vertical guide rails 2011 respectively, providing stable support and guidance for the main shaft clamp 201. During the lifting process, the close cooperation between the two vertical guide rails 2011 and the two columns of vertical sliders 2232 ensures the stability and accuracy of the main shaft assembly 2, avoiding shaking and deviation. At the same time, multiple support points distribute the stress during the lifting process, reducing the wear and fatigue of individual components. Optionally, each column of vertical sliders 2232 may be provided with one or more, and in this embodiment, each column of vertical sliders 2232 is provided with two. Furthermore, since the central axis of the main shaft 202 is located on the vertical symmetry plane of the two columns of vertical sliders 2232, it can be ensured that the main shaft 202 moves along a precise straight trajectory during lifting. Simultaneously, since the line connecting the central axis of the main shaft 202 and the third lead screw 231 is perpendicular to the vertical symmetry plane of the two columns of vertical sliders 2232, vibration and noise during lifting can be further reduced.

[0085] Specifically, a vertical block 2231 is provided on the second slide plate 223, and a vertical slider 2232 is provided on the side of the vertical block 2231 facing the main shaft clamp 201.

[0086] For further details, please refer to Figure 3 and Figures 13 to 17The denture processing cavity 12 is provided with a first mounting frame 31, a first worm gear 312, and a first worm wheel 313. The positioning plate driving mechanism includes a first positioning plate motor 311. The denture positioning plate 3 is mounted on the first mounting frame 31, and a first rotating shaft 314 is provided at the center of the denture positioning plate 3. The axis of the first rotating shaft 314 is perpendicular to the axis of the output shaft of the first positioning plate motor 311. The first worm gear 312 is coaxially connected to the output shaft of the first positioning plate motor 311, and the first worm wheel 313 is coaxially connected to the first rotating shaft 314. The first helical teeth on the first worm gear 312 mesh with the first gear teeth on the first worm wheel 313. When the first positioning plate motor 311 is started, the output shaft of the first positioning plate motor 311 drives the first worm gear 312 to rotate, the first worm gear 312 drives the first worm wheel 313 to rotate, the first worm wheel 313 drives the first rotating shaft 314 to rotate, and the first rotating shaft 314 drives the denture positioning plate 3 to rotate around the first rotating shaft 314. Specifically, the first rotation axis 314 is set along the Y-axis direction.

[0087] In this embodiment, unlike the prior art where the output shaft of the motor is coaxially connected to the plate that needs to be rotated, the axial direction of the first rotating shaft 314 in this embodiment is perpendicular to the axial direction of the output shaft of the first positioning plate motor 311. The first rotating shaft 314 and the output shaft of the first positioning plate motor 311 are connected by a first worm gear 313 and a first worm 312, which effectively reduces the space occupied by the first positioning plate motor 311 in the axial direction of the first rotating shaft 314, which is beneficial to the miniaturization design of the dental prosthesis carving machine.

[0088] Furthermore, the cavity wall of the denture processing cavity 12 is connected to a second mounting bracket 32, a second worm gear 322, a second worm wheel 323, and a second rotating shaft 324. The positioning plate drive mechanism also includes a second positioning plate motor 321. The first mounting bracket 31 is connected to one end of the second rotating shaft 324. The axial direction of the second rotating shaft 324 is perpendicular to the axial direction of the output shaft of the second positioning plate motor 321. The second worm gear 322 is coaxially connected to the output shaft of the second positioning plate motor 321, and the second worm wheel 323 is coaxially connected to the second rotating shaft 324. A second spiral is provided on the second worm gear 322. The teeth mesh with the second gear teeth on the second worm gear 323. When the second positioning plate motor 321 is started, the output shaft of the second positioning plate motor 321 drives the second worm 322 to rotate, the second worm 322 drives the second worm gear 323 to rotate, the second worm gear 323 drives the second rotating shaft 324 to rotate, and the second rotating shaft 324 drives the first mounting bracket 31 to rotate around the second rotating shaft 324. The axial direction of the first rotating shaft 314 and the axial direction of the second rotating shaft 324 are both horizontal, and the central axis of the first rotating shaft 314 is perpendicular to and intersects the central axis of the second rotating shaft 324. Specifically, the second rotating shaft 324 is set along the X-axis direction.

[0089] In this embodiment, the axial direction of the second rotating shaft 324 is perpendicular to the axial direction of the output shaft of the second positioning plate motor 321, and the second rotating shaft 324 and the output shaft of the second positioning plate motor 321 are connected by a second worm gear 323 and a second worm 322. This effectively reduces the space occupied by the second positioning plate motor 321 in the axial direction of the second rotating shaft 324, which is beneficial to the miniaturization design of the denture carving machine. Specifically, when the second positioning plate motor 321 is started, the output shaft of the second positioning plate motor 321 transmits power to the second rotating shaft 324 through the second worm gear 323 and the second worm 322, so that the second rotating shaft 324 rotates around its own central axis. The first mounting bracket 31 connected to the second rotating shaft 324 will also rotate with the second rotating shaft 324, thereby driving the denture positioning plate 3 mounted on it to rotate together.

[0090] Specifically, the first mounting bracket 31 includes a first plate 315 and a second plate 316 that are perpendicular to each other. The first plate 315 and the second plate 316 are combined in an "L" shape. The center of the first plate 315 is connected to the second rotating shaft 324. The denture positioning plate 3, the first positioning plate motor 311, the first worm gear 313, and the first worm 312 are all mounted on the second plate 316. In this embodiment, the first positioning plate motor 311 is used to drive the denture positioning plate 3 to rotate, and the second positioning plate motor 321 is used to drive the first mounting bracket 31 to rotate. Furthermore, the central axis of the first rotating shaft 314 is perpendicular to the second plate 316 and parallel to the first plate 315, and the central axis of the second rotating shaft 324 is perpendicular to the first plate 315 and parallel to the second plate 316. Thus, the vertical arrangement of the first rotating shaft 314 and the second rotating shaft 324 makes the entire transmission system more compact in space, maximizing the use of space and reducing the overall size of the denture carving machine, which is beneficial for miniaturization of the machine.

[0091] Preferably, the first positioning plate motor 311 is mounted on the first mounting bracket 31 on the side near the second mounting bracket 32, and the second positioning plate motor 321 is mounted on the second mounting bracket 32 ​​on the side near the first mounting bracket 31. Under the premise that the first positioning plate motor 311 occupies less space in the axial direction of the first rotating shaft 314 and the second positioning plate motor 321 occupies less space in the axial direction of the second rotating shaft 324, the mounting layout of the first positioning plate motor 311 and the second positioning plate motor 321 being close to each other further reduces the overall mounting space of the positioning plate drive mechanism and the worm gear transmission mechanism in the denture processing cavity 12, which is more conducive to the miniaturization design of the denture carving machine.

[0092] Specifically, the central axis of the first rotation axis 314 and the central axis of the second rotation axis 324 are set along the X-axis and Y-axis directions, respectively.

[0093] For further details, please refer to Figure 3 and Figure 10 The denture processing cavity 12 has at least one air blowing hole 121 and at least one dust suction hole 122 on its cavity wall. The air blowing hole 121 is used to connect to an external air blowing device and guide airflow into the denture processing cavity 12. The dust suction hole 122 is used to connect to an external air suction device and guide airflow out of the denture processing cavity 12. The denture processing cavity 12 includes a top space and a bottom space. The air blowing hole 121 is located in the top space, and the dust suction hole 122 is located in the bottom space. Optionally, the air blowing hole 121 is connected to an external air blowing device through an air blowing pipe 123, and the dust suction hole 122 is connected to an external air suction device through a dust suction pipe 124. It is understandable that during the carving process, dust particles tend to sink to the bottom of the denture processing cavity 12 due to gravity. In this embodiment, by setting a dust suction hole 122 in the bottom space of the denture processing cavity 12, these deposited dust particles can be sucked away more effectively. By setting the air blowing hole 121 in the top space of the denture processing cavity 12, the positive pressure airflow blows away the dust particles suspended at a higher position and guides them to flow downwards, eventually entering the dust suction hole 122 and being sucked away. This helps to form an airflow circulation from top to bottom in the denture processing cavity 12, improving the efficiency and comprehensiveness of dust removal.

[0094] Optionally, in this embodiment, the blowing hole 121 and the suction hole 122 are opened on the same side wall of the denture processing cavity 12, so that the airflow blown out by the blowing hole 121 and the suction airflow formed by the suction hole 122 can form a larger range of airflow circulation in the internal space of the denture processing cavity 12, and more effectively make the powder and debris in the denture processing cavity 12 discharged with the airflow circulation.

[0095] Furthermore, the denture processing cavity 12 also includes a central space located between the top space and the bottom space, where the tool magazine 4 and the denture positioning plate 3 of the denture carving machine are both located. It is understood that the tool magazine 4 and the denture positioning plate 3 serve as a storage device for carving tools and a support device for dentures, respectively. During the denture carving process, they inevitably accumulate a lot of dust. In this embodiment, by placing the air blower 121 in the upper space of the carving assembly, the airflow from the air blower 121 can disperse and carry away the dust located on the tool magazine 4 and the denture positioning plate 14. Subsequently, this airflow carrying dust is discharged through the dust suction hole 122 under the guidance of gravity, the cavity wall of the denture processing cavity 12, and the suction of the dust suction hole 122. This reduces the wear and blockage of the tools and denture positioning plate 3 by dust, extending the service life of the machine.

[0096] Optionally, to minimize the design size of the dental prosthesis carving machine, the outer wall of the carving machine body 1 in this embodiment can be recessed inward to house the control circuit board. Preferably, the dental prosthesis carving machine in this embodiment has a built-in power supply box, eliminating the need for an external power distribution box.

[0097] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
