The terms “comprising,” “including,” and “having” enumerate the stated features, quantities, operations, components, elements, and / or combinations thereof, but do not exclude the presence or addition of one or more other features, quantities, operations, components, elements, and / or combinations thereof.

[0054] See Figure 1 , Figure 2 , Figure 3 and Figure 4 In one embodiment of this utility model application, a denture grinding machine is disclosed, comprising a processing chamber 10, a clamping spindle 20, a triaxial guide tube, a grinding spindle 40, a tool magazine 50, and a control main board (not shown in the drawings). The processing chamber 10 has an operation window 11 on its front side for placing the denture to be processed. By placing the denture into the processing chamber 10 and then closing the operation window 11, the processing chamber 10 can be kept closed during processing, thereby preventing dust or water vapor from spilling into the surrounding environment and maintaining a clean environment.

[0055] like Figure 2 , Figure 3 and Figure 4 As shown, the processing chamber 10 has an assembly port 12 at the top and an insertion hole 13 on the side wall; the clamping spindle 20 is connected to the processing chamber 10; the clamping spindle 20 passes through the insertion hole 13 into the processing chamber 10 to clamp the denture; the three-axis guide rail 30 is located in the processing chamber 10 and extends above the assembly port 12; the grinding spindle 40 is located on the three-axis guide rail 30; the grinding spindle 40 passes through the assembly port 12 and extends into the processing chamber 10.

[0056] The three-axis guide rail 30 disclosed in this embodiment can drive the grinding spindle 40 to move flexibly in three-dimensional space, and has high control precision over the position of the grinding head 60 in spatial coordinates, thereby enabling precise grinding of the dentures on the holding spindle 20 and improving processing accuracy.

[0057] like Figure 2 As shown, the tool magazine 50 is located in the machining chamber 10; the tool magazine 50 is provided with a plurality of grinding heads 60; the grinding heads 60 are detachably assembled with the grinding spindle 40; the control main board is located in the machining chamber 10; the control main board is electrically connected to the clamping spindle 20, the three-axis guide rail 30 and the grinding spindle 40; the three-axis guide rail 30 is used to drive the grinding spindle 40 to move back and forth between the tool magazine 50 and the clamping spindle 20.

[0058] The denture grinding machine disclosed in this embodiment fixes the denture in the processing chamber 10 by clamping the spindle 20 during the processing. The control motherboard disclosed in this embodiment includes, but is not limited to, a printed circuit board. According to the processing requirements, the control motherboard sends control signals to make the three-axis guide rail 30 drive the grinding spindle 40 to move flexibly. In addition, during the grinding process, the grinding spindle 40 can be moved to the tool magazine 50 at any time to replace the grinding head 60, which replaces the operation window 11 and the operation of replacing the grinding head 60 in the traditional processing process.

[0059] In summary, the denture grinding machine disclosed in this embodiment can automatically and in one go process the dentures into shape. During the processing, the processing chamber 10 is kept closed, resulting in high processing efficiency and a well-sealed processing environment, which helps to reduce dust or water mist overflow and avoid environmental pollution.

[0060] like Figure 3As shown, in another embodiment of this application, the clamping spindle 20 includes a connecting seat 21, a driving member 22, and a chuck 23. The connecting seat 21 is connected to the processing chamber 10. The connecting seat 21 has a central hole, which is directly opposite the insertion hole 13. The driving member 22 is located on the side of the connecting seat 21 away from the insertion hole 13. The output end of the driving member 22 passes through the central hole. The chuck 23 is inserted into the insertion hole 13. One side of the chuck 23 is connected to the output end of the driving member 22, and the other side is used to clamp the denture.

[0061] The clamping spindle 20 disclosed in this embodiment not only clamps and fixes the denture, but also drives the chuck 23 to rotate via the drive component 22 to adjust the angle of the denture and perform all-round grinding of the denture to meet complex denture processing needs. Specifically, the drive component 22 disclosed in this embodiment can be a stepper motor or a DC motor, etc. A sealing ring can be provided on the chuck 23 to contact the side wall of the insertion hole 13, so as to maintain the airtightness of the insertion hole 13, further increasing the sealing degree in the processing chamber 10 and reducing the leakage of dust and water mist.

[0062] Specifically, the clamping spindle 20 disclosed in this embodiment can also be provided with a track at the rear end to advance or retract the clamping spindle 20, so as to cooperate with the grinding spindle 40 to perform more flexible processing operations.

[0063] like Figure 2 and Figure 3 As shown in another embodiment of this application, the dental prosthesis grinding machine includes a camera 70, which is disposed on the inner wall of the processing chamber 10 for photographing the dental prosthesis; and the camera 70 is electrically connected to the control main board. Since the processing chamber 10 is completely enclosed during processing, the internal processing situation cannot be directly observed with the naked eye. In this embodiment, by setting the camera 70 inside the processing chamber 10, the situation inside the processing chamber 10 is displayed through images, so that the operator can accurately judge the processing progress and effect, and then quickly adjust the processing parameters, further improving the control precision of the dental prosthesis processing.

[0064] For example Figure 2 and Figure 3 As shown, in another embodiment of this application, a gas channel is provided on the side wall of the processing chamber 10; the denture grinding machine includes an air purification component 80, which is connected to the processing chamber 10 and is used to connect to the gas channel.

[0065] After processing is completed, the processing chamber 10 disclosed in this embodiment still contains dust or water mist in the air. Therefore, an air purification component 80 is provided to filter the dust and water mist generated during processing to prevent pollution of the external environment. Specifically, the air purification component 80 includes a purification pipe connected to the outside of the processing chamber 10 and a filter block, such as activated carbon or filter cotton, installed inside the purification pipe to filter the gas flowing through the purification pipe.

[0066] like Figure 4 As shown, in another embodiment of this application, the processing chamber 10 includes a frame 14, a chamber 15, a cover 16, a bellows cover 17, and a mounting platform 18. The frame 14 is used to maintain stability, and the chamber 15 is mounted on the frame 14. The chamber 15 is hollow and can accommodate dentures for processing. Furthermore, the chamber 15 is tilted backward, so that water mist or dust generated during processing can accumulate at the rear of the chamber 15 due to gravity, facilitating collection and discharge. For example, in one embodiment of this application, a drain hole can be provided at the rear bottom of the chamber 15, and a collection box can be provided below the chamber 15, aligned with the drain hole, to collect dust or wastewater.

[0067] Specifically, the operation window 11, the assembly port 12, and the insertion hole 13 are all located on the cabin body 15; the cabin cover 16 is hinged to the cabin body 15 and is used to cover the operation window 11; furthermore, the edge of the cabin cover 16 is provided with a sealing strip. During processing, the cabin cover 16 is closed, and the sealing strip increases airtightness, keeping the cabin body 15 in a closed state and reducing the risk of powder or wastewater overflowing from the operation window 11.

[0068] Specifically, the bellows cover 17 is connected to the cabin 15 and covers the assembly port 12; the bellows cover 17 is used to fit the grinding spindle 40. Since the three-axis guide rail 30 will move the grinding spindle 40 during use, the grinding spindle 40 is actually constantly moving in the assembly port 12. By setting the bellows cover 17 on the grinding spindle 40, the flexibility, extensibility and good sealing of the bellows cover 17 can be taken into account both the flexibility of the movement of the grinding spindle 40 and the airtightness of the environment inside the cabin 15.

[0069] Specifically, the mounting platform 18 is located inside the housing 15 and is used to support the tool magazine 50. In this embodiment, the tool magazine 50 is also located inside the housing 15 to facilitate automatic tool changing, increasing flexibility and processing continuity. Placing the tool magazine 50 on the mounting platform 18, higher than the bottom surface of the housing 15, reduces dust or wastewater accumulation and minimizes contamination of the tool magazine 50. Preferably, the tool magazine 50 can be positioned on the mounting platform 18 so that the height of the grinding head 60 is the same as the height of the clamping spindle 20. This way, during tool changing operations, the grinding spindle 40 does not need to move up and down significantly; it only needs to move laterally after tool changing to re-engage with the denture, further increasing the speed of denture processing, reducing the difficulty of automation control, and improving processing accuracy.

[0070] Specifically, in this embodiment, the frame 14, the chamber 15, and the mounting platform 18 are integrally formed. High-hardness steel can be used for integral casting, ensuring structural stability of the chamber 15, frame 14, and mounting platform 18, eliminating the assembly process, and solving the problem of unavoidable contact gaps during assembly. During processing, there is no need to worry about dust or water mist leaking from the gaps; wastewater or dust can be completely collected, reducing contamination of the processing chamber 10 and extending the service life of the denture grinding machine; it also reduces pollution to the surrounding environment.

[0071] Moreover, since the housing 15 is directly molded without any assembly gaps, it can be used for both dry and wet cutting scenarios, increasing the application range of the denture grinding machine and meeting more processing needs.

[0072] In addition, molding multiple components into one piece can improve manufacturing efficiency, reduce production costs, facilitate structural integration and optimization, and make it easier to manufacture products that are small in size, high in precision, and can be flexibly applied in clinical settings.

[0073] For example Figure 4 As shown, in another embodiment of this application, a support plane 141 is inclinedly arranged on the frame 14, and the inclination angle of the support plane 141 is the same as the inclination angle of the cabin 15. In this embodiment, a three-axis guide rail 30 is arranged on the support plane 141, and the support plane 141 is inclined at the same angle as the cabin 15, so as to arrange the guide rail according to the shape of the space inside the cabin 15, so as to establish a spatial coordinate system applicable to the space inside the cabin 15.

[0074] Specifically, such as Figure 3 and Figure 5As shown, the three-axis guide rail 30 includes an x-axis slide rail 31, an x-axis slider 32, and an x-axis motor 33. The x-axis slide rail 31 is disposed on the support plane 141, and the x-axis slider 32 is slidably disposed on the x-axis slide rail 31. The x-axis motor 33 is disposed at the end of the x-axis slide rail 31 and is connected to the x-axis slider 32 in a transmission connection.

[0075] The three-axis guide rail 30 also includes a z-axis slide rail 34, a z-axis slider 35, and a z-axis motor 36. The z-axis slide rail 34 is connected to the x-axis slider 32, and the top of the z-axis slide rail 34 is higher than the assembly port 12. The z-axis slider 35 is slidably disposed on the z-axis slide rail 34. The z-axis motor 36 is disposed at the end of the z-axis slide rail 34 and is connected to the z-axis slider 35 in a transmission connection.

[0076] The three-axis guide rail 30 also includes a Y-axis slide rail 37, a Y-axis slider 38, and a Y-axis motor 39. The Y-axis slide rail 37 is connected to the Z-axis slider 35, and one end of the Y-axis slide rail 37 extends directly above the assembly port 12. The Y-axis slider 38 is slidably disposed on the Y-axis slide rail 37. The Y-axis motor 39 is disposed at the end of the Y-axis slide rail 37 and is connected to the Y-axis slider 38 in a transmission manner. The grinding spindle 40 is connected to the Y-axis slider 38.

[0077] Furthermore, the x-axis slide 31 extends along the width direction of the cabin 15; the y-axis slide 37 extends along the depth direction of the cabin 15; and the z-axis slide 34 extends along the height direction of the cabin 15.

[0078] In this embodiment, the three-axis guide rail 30, by establishing slides extending along the x, y, and z axes in the spatial coordinate system, can precisely control the spatial position of the grinding spindle 40. The x-axis motor 33, y-axis motor 39, and z-axis motor 36 disclosed in this embodiment can be selected according to the required power, for example, using stepper motors, DC motors, etc. Preferably, the x-axis motor 33, y-axis motor 39, and z-axis motor 36 are of the same type and model to optimize manufacturing costs and facilitate assembly and production.

[0079] Specifically, in this embodiment, the x-axis motor 33, y-axis motor 39 and z-axis motor 36 are all electrically connected to the control motherboard via wires. The control motherboard precisely controls the positions of the x-axis slider 32, y-axis slider 38 and z-axis slider 35, thereby determining the position of the grinding spindle 40 and achieving the effects of tool changing and precise grinding.

[0080] Specifically, as another embodiment of this application, the installation platform 18 is disclosed located on the side of the housing 15 opposite to the insertion hole 13. In this embodiment, a clamping spindle 20 is inserted into the insertion hole 13. The installation platform 18 is positioned away from the insertion hole 13 to avoid the clamping spindle 20, thus rationally distributing the tool magazine 50 and the clamping spindle 20. Furthermore, since the denture is fixed to the clamping spindle 20, during processing, there is often a lot of dust or water mist around the clamping spindle 20. By positioning the tool magazine 50 away from the clamping spindle 20, dust accumulation and water mist pollution can be reduced.

[0081] like Figure 6 As shown in another embodiment of this application, the tool magazine 50 includes a base 51, a tool setter 52, a tool holder 53, and a latch 54. The base 51 has a fixed platform 511 on one side and a tool changing slot 512 on the other side. The tool changing slot 512 has an insertion port on the side facing away from the fixed platform 511. The tool setter 52 is located on the fixed platform 511. The tool holder 53 is inserted into the tool changing slot 512 through the insertion port. The tool holder 53 has a plurality of slots 531 arranged in an array for inserting the grinding head 60. The latch 54 is hinged to the base 51 and located on the side of the insertion port. The latch 54 can rotate to the insertion port to abut against the tool holder 53.

[0082] The tool magazine 50 disclosed in this embodiment can be manufactured independently, and the base 51 is fixed to the inner wall of the machining chamber 10 by welding, bonding or other methods. A tool setter 52 is set on the fixed table 511. The position of the tool setter 52 is relatively fixed with the tool holder 53 and with each slot 531 on the tool holder 53. Therefore, each time a tool is changed, it is only necessary to first move the grinding spindle 40 to align with the tool setter 52 via the three-axis guide rail 30, and then move it to the slot 531 to accurately assemble or disassemble the grinding head 60.

[0083] Specifically, in this embodiment, the side of the tool changing slot 512 forms an insertion port, so the tool holder 53 is detachably connected to the base 51 and fixed or released by the buckle 54. When processing different dentures, different tool holders 53 can be selectively assembled to fix different types and sizes of grinding heads 60 in the processing chamber 10 to achieve the following effects:

[0084] According to the processing requirements, the grinding heads 60 are placed on the tool holder 53 in a certain order and fixed in the processing chamber 10. During the processing, according to the order of use of the grinding heads 60, the corresponding grinding heads 60 are assembled onto the grinding spindle 40 in sequence to process the final shape of the denture in one go, improving processing efficiency and eliminating the need to open the processing chamber 10 midway.

[0085] Specifically, as another embodiment of this application, a grinding method is disclosed, applied to any of the above-described denture grinding machines; wherein, the grinding method includes:

[0086] Step S10: Place the denture to be processed into the processing chamber 10 and fix it on the clamping spindle 20;

[0087] Step S20: Start the three-axis guide rail 30, move the grinding spindle 40 to the tool magazine 50, and assemble the grinding head 60 onto the grinding spindle 40;

[0088] Step S30: Move the grinding spindle 40 toward the clamping spindle 20 until the grinding cutter head 60 contacts the denture;

[0089] Step S40: Start the grinding spindle 40 and drive the grinding cutter head 60 to grind the denture.

[0090] The denture grinding machine disclosed in this embodiment can process fully automatically and has high processing efficiency. After the denture to be processed is placed into the processing chamber 10, the appropriate grinding head 60 is assembled onto the grinding spindle 40, and the processing can be completed in one go. The processing chamber 10 does not need to be opened in the middle, which can maintain the closed environment inside the processing chamber 10 and reduce the leakage of dust or water mist.

[0091] Specifically, as another embodiment of this application, after disclosing step S40, the following is also included:

[0092] Step S40: Pause the grinding spindle 40;

[0093] Step S50: Start the three-axis guide rail 30, move the grinding spindle 40 to the tool magazine 50, and replace the grinding head 60;

[0094] Step S60: Move the grinding spindle 40 toward the clamping spindle 20 until the grinding head 60 contacts the denture again;

[0095] Step S70: Start the grinding spindle 40 to perform secondary grinding on the denture.

[0096] The grinding method disclosed in this embodiment is applicable to denture manufacturing processes with multiple processing steps. When a single grinding head 60 is insufficient to fully shape the denture during processing, the grinding spindle 40 can be paused, moved to the tool magazine 50, and the grinding head 60 replaced before proceeding to the second stage of processing. Even if three processing steps are required, the above steps can be repeated, replacing the grinding head 60 on the grinding spindle 40 once more. Therefore, the flexibility of the denture grinding machine is improved, and the final shape of the denture is ensured to be produced in one pass, maintaining a closed environment within the processing chamber 10 during the processing.
