Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0033] Referring to the accompanying drawings Figures 1 to 6 The embodiment of the present application provides a false tooth carving machine, which comprises a carving machine body 10, a main shaft assembly 50 and a main shaft transmission mechanism installed in the carving machine body 10. It can be understood that the false tooth carving machine body 10 is provided with a transmission mechanism mounting cavity and a false tooth processing operation cavity. The main shaft transmission mechanism is installed in the transmission mechanism mounting cavity, and the lower end of the main shaft assembly 50 penetrates into the false tooth processing operation cavity through the transmission mechanism mounting cavity. In the working process of false tooth processing, the main shaft assembly 50 is driven by the main shaft transmission mechanism to displace in the X-axis direction, the Y-axis direction and the Z-axis direction respectively, so as to drive the carving cutter installed at the lower end of the main shaft assembly 50 to cut or polish the false tooth in the false tooth processing operation cavity.

[0034] The main shaft transmission mechanism comprises a first mounting seat 20, a first guide rail 21 and a first movable channel 22 are arranged on the first mounting seat 20, the first guide rail 21 is arranged along the X-axis direction; a second mounting seat 30, the second mounting seat 30 is slidably connected to the first guide rail 21, a second guide rail 31 and a second movable channel 32 are arranged on the second mounting seat 30, the second guide rail 31 is arranged along the Y-axis direction; a third mounting seat 40, the third mounting seat 40 is slidably connected to the second guide rail 31, a third movable channel 41 is arranged on the third mounting seat 40, the main shaft assembly 50 is connected to the third mounting seat 40 and penetrates through the third movable channel 41, the second movable channel 32 and the first movable channel 22 along the Z-axis direction; wherein, when the second mounting seat 30 slides along the first guide rail 21, the main shaft assembly 50 moves in the first movable channel 22 along the X-axis direction; when the third mounting seat 40 slides along the second guide rail 31, the main shaft assembly 50 moves in the first movable channel 22 and the second movable channel 32 along the Y-axis direction.

[0035] In the present embodiment, through the layered arrangement of the first mount 20, the second mount 30 and the third mount 40, the cooperation between the first mount 20 and the second mount 30 is responsible for the sliding of the main shaft in the X-axis direction, the cooperation between the third mount 40 and the second mount 30 is responsible for the sliding of the main shaft in the Y-axis direction, and by arranging the main shaft assembly 50 to pass through the first active channel 22, the second active channel 32 and the third active channel 41 to allow the movement of the main shaft assembly 50 in the Z-axis direction, the movement of the main shaft assembly 50 in each direction can be independently controlled and does not interfere with each other. When the second mount 30 slides in the X-axis direction along the first guide rail 21, the main shaft assembly 50 remains relatively fixed through the third mount 40 and the second active channel 32, but it moves in the first active channel 22 along the X-axis direction, which realizes the precise positioning of the main shaft assembly 50 in the X-axis direction. When the third mount 40 slides in the Y-axis direction along the second guide rail 31, the main shaft assembly 50 moves in the first active channel 22 and the second active channel 32 along the Y-axis direction, which realizes the precise positioning of the main shaft assembly 50 in the Y-axis direction. Further, the main shaft assembly 50 is slidably connected to the third mount 40 in the Z-axis direction, and then the main shaft assembly 50 moves upward or downward in the Z-axis direction through the third active channel 41, the second active channel 32 and the first active channel 22. It can be understood that in the present embodiment, through the layered arrangement of the first mount, the second mount and the third mount, and the sliding connection between them, the precise movement of the main shaft assembly in the three-dimensional space is realized, so that the mass distribution of the main shaft on the main shaft transmission mechanism is more uniform, the single direction bias is reduced, and the requirement for the strength of the guide rail is reduced. Due to the optimization of the mass distribution of the main shaft and the main shaft transmission mechanism, the first guide rail and the second guide rail in the denture carving machine of the present embodiment can adopt a smaller size guide rail, without relying on the traditional high-strength large guide rail, which not only reduces the volume and weight of the equipment, but also improves the portability and flexibility of the equipment, which is beneficial to the miniaturization design of the denture carving machine.

[0036] Optionally, the width of the first movable channel 22 along the X-axis direction is greater than the width of the second movable channel 32 along the X-axis direction, and the width of the second movable channel 32 along the Y-axis direction is greater than the width of the third movable channel 41 along the Y-axis direction. It can be understood that the width of the first movable channel 22 along the X-axis direction is greater than the width of the second movable channel 32 along the X-axis direction, mainly considering that as the first mounting seat 20, the second mounting seat 30, and the third mounting seat 40 are stacked from the bottom layer to the top layer, the mounting seat closer to the top layer (such as the third mounting seat 40) is limited by the boundary of the lower layer mounting seat (such as the second mounting seat 30), so the width of the movable channel thereof can be correspondingly reduced to further promote the miniaturization design of the denture carving machine. Similarly, the width of the second movable channel 32 along the Y-axis direction is greater than the width of the third movable channel 41 along the Y-axis direction, which is also for optimizing the space utilization, reducing unnecessary space waste, and making the entire transmission mechanism more compact.

[0037] Optionally, the volume of the second mounting seat 30 is smaller than the first mounting seat 20, and the volume of the third mounting seat 40 is smaller than the second mounting seat 30. It can be understood that the volume of the second mounting seat 30 is smaller than the first mounting seat 20, mainly considering that the first mounting seat 20 as the bottom support needs to bear the weight of the entire transmission mechanism and provide a stable sliding foundation, so its volume and weight are relatively large, while the second mounting seat 30 only needs to provide Y-axis direction movement on the basis of the first mounting seat 20, so its volume and weight can be correspondingly reduced. The volume of the third mounting seat 40 is smaller than the second mounting seat 30, because the third mounting seat 40 only needs to bear the weight of the spindle assembly 50 on the basis of the second mounting seat 30, so its volume can be further reduced. The gradual reduction of the volume of the first mounting seat 20, the second mounting seat 30, and the third mounting seat 40 makes the mass distribution of the entire transmission mechanism more uniform, which is beneficial to reducing the width of the first guide rail 21, the second guide rail 31, and the third guide rail, and helps the miniaturization design of the denture carving machine.

[0038] Specifically, the first mounting seat 20 is provided with two first guide rails 21, and the first movable channel 22 is opened between the two first guide rails 21. It can be understood that the design of the first movable channel 22 ensures that the spindle assembly 50 does not interfere with the first mounting seat 20 or other structures during movement, and the first movable channel 22 is opened between the two first guide rails 21, effectively utilizing the space and avoiding unnecessary space waste. During the action, as the second mounting seat 30 slides along the two first guide rails 21 in the X-axis direction, the spindle assembly 50 moves in the first movable channel 22 along the X-axis direction through the third mounting seat 40 and the second movable channel 32, and the two first guide rails 21 provide stable support and guidance for the second mounting seat 30, ensuring the movement precision and stability of the spindle assembly 50 in the X-axis direction.

[0039] Further, the center of gravity of the first assembly composed of the second mounting seat 30, the third mounting seat 40 and the spindle assembly 50 is located between the two first guide rails 21. It needs to be explained that in mechanics, the position of the center of gravity of an object has an important influence on its stability. When the center of gravity of an object is located near the geometric center of the support surface, the object is more likely to remain stable when subjected to external forces. Therefore, in the embodiment, the center of gravity of the first assembly is designed to be between the two first guide rails 21, which can ensure that the first assembly can maintain good stability when moving in the X-axis direction, reduce shaking and errors, and the first guide rails 21 can bear the weight more evenly, reducing wear and deformation caused by uneven weight distribution. Therefore, the first guide rails 21 in the embodiment can be appropriately reduced in width compared to traditional high-strength large guide rails.

[0040] Specifically, the second mounting seat 30 is provided with two second guide rails 31, and the second movable channel 32 is formed between the two second guide rails 31. It can be understood that the second movable channel 32 is formed between the two second guide rails 31, which ensures that the third mounting seat 40 does not interfere with the second mounting seat 30 or other structures when moving the spindle assembly 50 in the Y-axis direction, while maintaining the compactness of the structure.

[0041] Further, the center of gravity of the second assembly composed of the third mounting seat 40 and the spindle assembly 50 is located between the two second guide rails 31. In the embodiment, the center of gravity of the second assembly is designed to be between the two second guide rails 31, which can ensure that the second assembly can maintain good stability when moving in the Y-axis direction, reduce shaking and errors, and the second guide rails 31 can bear the weight more evenly, reducing wear and deformation caused by uneven weight distribution. Therefore, the second guide rails 31 in the embodiment can be appropriately reduced in width compared to traditional high-strength large guide rails.

[0042] Further, the second movable channel 32 is formed in the middle of the second mounting seat 30.

[0043] Further, the third movable channel 41 is formed in the middle of the third mounting seat 40.

[0044] Further, the first screw block assembly includes a first driving member, a first screw rod and a first transmission nut. The first screw rod is arranged along the X-axis direction. The output shaft of the first driving member is transmissionally connected to the first screw rod. The first transmission nut is screwed to the first screw rod. The second mounting seat 30 is connected to the first transmission nut. When the first driving member is started, it drives the first screw rod to rotate, and in turn drives the first transmission nut to move linearly along the first screw rod, i.e., the X-axis direction. The first transmission nut drives the second mounting seat 30 and the components mounted thereon to move in the X-axis direction.

[0045] Further, the second screw rod and sliding block assembly further comprises a second driving element, a second screw rod and a second transmission nut, the second screw rod is arranged along the Y axis direction, the output shaft of the second driving element is in transmission connection with the second screw rod, the second transmission nut is screwed on the second screw rod, and the third mounting base 40 is connected to the second transmission nut.

[0046] Further, the third screw rod and sliding block assembly further comprises a third driving element, a third screw rod and a third transmission nut, the third screw rod is arranged along the Z axis direction, the output shaft of the third driving element is in transmission connection with the third screw rod, the third transmission nut is screwed on the third screw rod, and the main shaft assembly 50 is connected to the third transmission nut.

[0047] In an embodiment, the main shaft transmission mechanism is installed in the transmission mechanism installation cavity of the false tooth carving machine, the first screw rod and sliding block assembly is arranged on the first mounting base 20 and is used for driving the second mounting base 30 to slide along the first guide rail 21, the second screw rod and sliding block assembly is arranged on the second mounting base 30 and is used for driving the third mounting base 40 to slide along the second guide rail 31, and the third screw rod and sliding block assembly is arranged on the third mounting base 40 and is used for driving the main shaft assembly 50 to ascend and descend along the Z axis direction in the third movable channel 41, the second movable channel 32 and the first movable channel 22.

[0048] The above is only used for further illustrating the technical content of the present application by means of embodiments, so as to make the reader more easily understand, but does not represent that the embodiments of the present application are limited to this, any technical extension or re-creation made according to the present application is also protected by the present application.
