Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis carving technology, specifically a dental prosthesis forming device with a multi-axis linkage carving head. Background Technology

[0002] In the field of denture forming devices with multi-axis linkage carving heads, traditional denture carving devices are mostly single-axis or simple three-axis drive structures, lacking flexible angle adjustment components. They can only achieve basic linear movement and cannot accurately match the carving needs of complex anatomical morphology such as the crown surface and occlusal grooves of dentures. In addition, some devices have insufficient clamping stability for carving cutters, and cutter head deviation is prone to occur during processing, resulting in low denture forming accuracy and difficulty in adapting to customized restoration scenarios.

[0003] Furthermore, the low level of automation not only increases the intensity of manual operation but also makes it easy for human error to affect the processing accuracy. It also cannot efficiently connect different processes such as roughing and fine carving, making it difficult to meet the needs of mass production of personalized dentures. Most devices lack blank position detection and calibration functions, and blank placement deviations cannot be detected and corrected in time, resulting in inaccurate carving positioning, which in turn leads to denture processing dimensional deviations, affecting the restoration effect and making it difficult to meet the clinical demand for high-precision denture processing. Utility Model Content

[0004] The purpose of this invention is to solve the problems of traditional devices being mostly single-axis or simple three-axis driven, lacking flexible angle adjustment components, and having insufficient cutting head clamping stability, resulting in low forming accuracy. This invention provides a denture forming device with a multi-axis linkage engraving head.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A denture forming device with a multi-axis linkage carving head includes a frame base, a movable support at the top of the frame base, an x-axis moving component at the front top of the movable support, a lifting component slidably connected to the side wall of the x-axis moving component, a tool angle adjusting component at the front bottom of the lifting component, a tool clamping mechanism at the front end of the tool angle adjusting component, a denture position adjusting component at the top side of the frame base, a denture carving auxiliary mechanism slidably connected to the top side of the side wall of the denture position adjusting component, a vacuum cleaner at the top side of the denture carving auxiliary mechanism, and a control panel at the right side of the movable support.

[0007] Furthermore, the x-axis moving assembly includes a rotary motor and a lead screw. The rear end of the lifting assembly is slidably connected to the side wall of the lead screw. The output end of the rotary motor is connected to the left end of the lead screw. The rotary motor and the lead screw are located on the upper front side of the movable bracket. The rotary motor of the x-axis moving assembly is started through the control panel, and its output end drives the lead screw to rotate.

[0008] Furthermore, the lifting assembly includes a support frame, a second rotary motor, and a second lead screw. The tool angle adjustment assembly is located at the front of the bottom end of the support frame, and the second rotary motor is located at the top end of the support frame. The bottom output end of the second rotary motor is connected to the top end of the second lead screw. The bottom end of the second lead screw movably passes through the rear side of the support frame. When the second rotary motor of the lifting assembly is started, its bottom output end drives the second lead screw to rotate. The bottom end of the second lead screw passes through the rear side of the support frame, and when rotating, it drives the entire support frame to rise and fall vertically.

[0009] Furthermore, the tool angle adjustment assembly includes a tripod, a third rotary motor, and a fourth rotary motor. The two ends of the tripod are rotatably connected to the front bottom end of the lifting assembly via the third rotary motor. The front output end of the fourth rotary motor passes through the middle of the tripod and is connected to the rear end of the tool clamping mechanism. For the curved surface of the denture, the tool angle adjustment assembly is used to adjust the tool head posture.

[0010] Furthermore, the tool clamping mechanism includes a tool controller and a tool clamping assembly. The tool clamping assembly is movably disposed at the bottom end of the tool controller. The front end of the tool angle adjustment assembly is movably connected to the rear end of the tool clamping assembly. A suitable engraving tool head is selected and placed between clamping block one and clamping block two of the tool clamping assembly.

[0011] Furthermore, the tool clamping assembly includes a clamping block one, an electric push rod, an engraving head, and a clamping block two. The clamping block one and the clamping block two are movably connected and merged together by the electric push rod. The inner middle of the clamping block one and the clamping block two are movably clamped to the top of the outer side wall of the engraving head. The multi-axis assembly works together to move the tool clamping mechanism above the tool head replacement frame. The electric push rod retracts, and the clamping block one and the clamping block two release the old tool, which falls into the corresponding tool slot of the tool head replacement frame.

[0012] Furthermore, the denture position adjustment assembly includes a worktable support, a rotary motor five, and a lead screw three. The worktable support, the rotary motor five, and the lead screw three are all disposed on the top side of the frame base. The bottom side of the denture carving auxiliary mechanism is slidably connected to the top side of the worktable support, and the side wall of the lead screw three is rotatably connected to the bottom side of the denture carving auxiliary mechanism. The output end of the rotary motor five is connected to the rear end of the lead screw three. Since the bottom side of the denture carving auxiliary mechanism is rotatably connected to the side wall of the lead screw three and the top side is slidably connected to the top side of the worktable support, the rotation of the lead screw three is converted into linear movement of the denture carving auxiliary mechanism along the y-axis (horizontal longitudinal direction).

[0013] Furthermore, the denture carving auxiliary mechanism includes a denture clamping assembly and a tool replacement holder. The tool replacement holder is located at the rear end of the denture clamping assembly. A tool change command is sent through the control panel: the multi-axis assembly works together to move the tool clamping mechanism above the tool replacement holder, and the clamping block re-clamps the new tool to complete the tool change.

[0014] Furthermore, the denture clamping assembly includes a support body, an electric cylinder, a clamping platform, an elastic fitting pad, and a displacement sensor. The support body is disposed at both ends of the top side of the frame base. The outer end of the electric cylinder is disposed inside the inner end of the support body, and the inner end of the electric cylinder is fixedly connected to the outer side of the clamping platform. The elastic fitting pad is disposed inside the clamping platform, and the displacement sensor is disposed inside the elastic fitting pad. The electric cylinder inside the support body pushes the clamping platform to move inward until the elastic fitting pad inside the clamping platform completely fits the side wall of the blank—the elastic fitting pad can avoid hard contact damage to the blank.

[0015] Compared with the prior art, this utility model provides a denture forming device with a multi-axis linkage carving head, which has the following beneficial effects:

[0016] 1. This denture forming device with a multi-axis linkage carving head utilizes a multi-axis linkage structure consisting of an x-axis moving component, a lifting component, and a tool angle adjustment component. Combined with a tool clamping mechanism for stable clamping and precise control of the carving head, it can flexibly adapt to complex anatomical shapes of dentures. The linear movement of the x / y / z axes and the angular rotation of the A / C axes achieve multi-axis linkage. With the assistance of automated blank clamping, tool replacement, and dust cleaning, it can accurately adapt to the carving needs of complex denture shapes, balancing processing accuracy and ease of operation. It is suitable for mass production of personalized dentures or customized restoration processing scenarios.

[0017] 2. This denture forming device with a multi-axis linkage engraving head uses an electric cylinder to drive the clamping table in conjunction with an elastic fitting pad, which can stably clamp denture blanks of different sizes and avoid damage from hard contact. The internal displacement sensor can also detect the position of the blank in real time and provide feedback for calibration, further ensuring the accuracy of engraving positioning. The rear cutter head replacement frame facilitates the quick replacement of different types of engraving cutters, adapting to the needs of different processing stages such as roughing and fine engraving, and improving processing efficiency.

[0027] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1:

[0029] like Figure 1 and Figure 2 As shown, a denture forming device with a multi-axis linkage carving head includes a frame base 1, a movable support 2 on the top of the frame base 1, and an x-axis moving component 3 on the front side of the top of the movable support 2. The x-axis moving component 3 includes a rotary motor 31 and a lead screw 32. The rear end of a lifting component 4 is slidably connected to the side wall of the lead screw 32. The output end of the rotary motor 31 is connected to the left end of the lead screw 32. The rotary motor 31 and the lead screw 32 are located on the upper front side of the movable support 2. The rotary motor 31 of the x-axis moving component 3 is started by the control panel 10, and its output end drives the lead screw 32 to rotate. Since the rear end of the lifting component 4 is slidably connected to the side wall of the lead screw 32, the rotation of the lead screw 32 is converted into linear movement of the lifting component 4 along the x-axis direction, thereby driving the tool angle adjustment component 5 and the tool clamping mechanism 6 to move synchronously.

[0030] like Figure 4As shown, a lifting assembly 4 is slidably connected to the side wall of the x-axis moving assembly 3. The lifting assembly 4 includes a support frame 41, a second rotary motor 42, and a second lead screw 43. The tool angle adjustment assembly 5 is located at the bottom front side of the support frame 41. The second rotary motor 42 is located at the top side of the support frame 41. The bottom output end of the second rotary motor 42 is connected to the top end of the second lead screw 43. The bottom end of the second lead screw 43 extends through the rear side of the support frame 41. When the second rotary motor 42 of the lifting assembly 4 is started, its bottom output end drives the second lead screw 43 to rotate. The bottom end of the second lead screw 43 extends through the rear side of the support frame 41, and when rotating, it drives the entire support frame 41 to rise and fall in the vertical direction.

[0031] like Figure 5 As shown, a tool angle adjustment component 5 is provided on the front side of the bottom end of the lifting assembly 4. The tool angle adjustment component 5 includes a tripod 51, a rotary motor 52, and a rotary motor 53. The two ends of the tripod 51 are rotatably connected to the bottom front end of the lifting assembly 4 through the rotary motor 52. The front output end of the rotary motor 53 passes through the middle of the tripod 51 and is connected to the rear end of the tool clamping mechanism 6. When the rotary motor 52 is started, its output end drives the tripod 51 to rotate around the horizontal axis (A-axis) of the bottom front end of the lifting assembly 4, thereby realizing the pitch angle adjustment of the engraving tool head 623. When the rotary motor 53 is started, its front output end drives the tool clamping mechanism 6 to rotate around the vertical axis (C-axis) of the middle part of the tripod 51.

[0032] like Figure 5 and Figure 6 As shown, a tool clamping mechanism 6 is provided at the front end of the tool angle adjustment component 5. The tool clamping mechanism 6 includes a tool controller 61 and a tool clamping component 62. The tool clamping component 62 is movably disposed at the bottom end of the tool controller 61. The front end of the tool angle adjustment component 5 and the rear end of the tool clamping component 62 are movably connected. The tool clamping component 62 includes a clamping block 1 621, an electric push rod 622, an engraving head 623, and a clamping block 2 624. The clamping block 1 621 and the clamping block 2 624 are movably connected and merged together through the electric push rod 622. The inner middle of the clamping block 1 621 and the clamping block 2 624 are movably clamped on the top of the outer wall of the engraving head 623. When it is necessary to switch tools, a tool change command is sent through the control panel 10: the multi-axis component works together to move the tool clamping mechanism 6 above the tool head replacement frame 82, the electric push rod 622 retracts, and the clamping block 1 621 and the clamping block 2 624 release the old tool.

[0033] like Figure 3As shown, a denture position adjustment assembly 7 is provided on the top side of the frame base 1. The denture position adjustment assembly 7 includes a worktable support 71, a rotary motor 72, and a lead screw 73. The worktable support 71, the rotary motor 72, and the lead screw 73 are all located on the top side of the frame base 1. The bottom side of the denture carving auxiliary mechanism 8 is slidably connected to the top side of the worktable support 71. The output end of the rotary motor 72 is connected to the rear end of the lead screw 73. While the carving cutter head is being adjusted, the rotary motor 72 of the denture position adjustment assembly 7 is started, and its output end drives the lead screw 73 to rotate. Since the bottom side of the denture carving auxiliary mechanism 8 is rotatably connected to the side wall of the lead screw 73 and the top side is slidably connected to the top side of the worktable support 71, the rotation of the lead screw 73 is converted into a linear movement of the denture carving auxiliary mechanism 8 along the y-axis (horizontal longitudinal direction).

[0034] Example 2:

[0035] like Figure 3 , Figure 7 and Figure 8 As shown, a denture carving auxiliary mechanism 8 is slidably connected to the top side of the side wall of the denture position adjustment component 7. The side wall of the lead screw 73 is rotatably connected to the bottom side of the denture carving auxiliary mechanism 8. The denture carving auxiliary mechanism 8 includes a denture clamping component 81 and a cutter replacement holder 82. The cutter replacement holder 82 is located at the rear end of the denture clamping component 81. The denture clamping component 81 includes a support body 811, an electric cylinder 812, a clamping platform 813, an elastic fitting pad 814, and a displacement sensor 815. The support body 811 is located at both ends of the top side of the frame base 1. The outer end of the electric cylinder 812 is located inside the inner end of the support body 811. The inner end of the electric cylinder 812 is fixedly connected to the outer side of the clamping platform 813. The fitting pad 814 is located inside the clamping stage 813, and the displacement sensor 815 is located inside the elastic fitting pad 814. The denture blank to be processed is placed between the clamping stages 813 of the denture carving auxiliary mechanism 8. The denture clamping assembly 81 is activated through the control panel 10: the electric cylinder 812 inside the support body 811 pushes the clamping stage 813 to move inward until the elastic fitting pad 814 inside the clamping stage 813 is completely in contact with the side wall of the blank. The elastic fitting pad 814 can avoid hard contact damage to the blank. At the same time, the displacement sensor 815 detects the position of the blank in real time and feeds the data back to the control panel 10 to automatically calibrate the initial alignment relationship between the center point of the blank and the carving head 623.

[0036] like Figure 1 As shown, a vacuum cleaner 9 is installed on the top side of the dental prosthesis carving auxiliary mechanism 8, and a control panel 10 is installed on the right side of the movable bracket 2. The vacuum cleaner 9 uses negative pressure to adsorb ceramic chips and resin dust generated during the carving process, ensuring that dust does not accumulate on the surface of the blank or at the carving head.

[0037] Working principle: such as Figures 1-8As shown, the precise clamping and positioning of the denture blank is as follows: First, the denture blank to be processed is placed between the clamping tables 813 of the denture carving auxiliary mechanism 8. The denture clamping assembly 81 is started through the control panel 10: the electric cylinder 812 inside the support body 811 pushes the clamping table 813 to move inward until the elastic contact pad 814 inside the clamping table 813 is completely in contact with the side wall of the blank. The elastic contact pad 814 can avoid hard contact damage to the blank. At the same time, the displacement sensor 815 detects the position of the blank in real time and feeds the data back to the control panel 10. The initial alignment relationship between the center point of the blank and the carving head 623 is automatically calibrated to ensure that the blank is in the reference position within the carving range.

[0038] Installation of the engraving cutter head 623: According to the denture processing requirements, select the appropriate engraving cutter head 623 and place it between clamping block 1 621 and clamping block 2 624 of the tool clamping assembly 62; send a command through the control panel 10 to start the electric push rod 622, which pushes clamping block 1 621 and clamping block 2 624 to move towards each other until the inner sides of the two clamp the top sidewall of the engraving cutter head 623 tightly; then the tool controller 61 initializes the engraving parameters to prepare for engraving;

[0039] Multi-axis linkage positioning stage: The device achieves multi-dimensional precise alignment between the carving cutter head 623 and the denture blank through the coordinated action of the x-axis moving component 3, the lifting component 4, the cutter angle adjustment component 5, and the denture position adjustment component 7, adapting to the carving needs of different parts of the denture.

[0040] X-axis (horizontal) position adjustment: Start the rotary motor 31 of the X-axis moving component 3 through the control panel 10, and its output end drives the lead screw 32 to rotate; Since the rear end of the lifting component 4 is slidably connected to the side wall of the lead screw 32, the rotation of the lead screw 32 is converted into the linear movement of the lifting component 4 along the X-axis direction, thereby driving the tool angle adjustment component 5 and the tool clamping mechanism 6 to move synchronously, and determining the initial carving position of the carving head 623 in the horizontal direction;

[0041] Z-axis (vertical direction) height adjustment: Start the rotary motor 42 of the lifting assembly 4, and its bottom output end drives the lead screw 43 to rotate; the bottom end of the lead screw 43 passes through the rear side of the support frame 41, and when rotating, it drives the support frame 41 to rise and fall in the vertical direction, thereby adjusting the vertical height of the engraving cutter head 623.

[0042] Carving cutter head angle (A / C axis) adjustment: For the curved surface of the denture, the cutter head posture needs to be adjusted by the cutter head angle adjustment component 5: Start the rotary motor 3 52, its output end drives the tripod 51 to rotate around the horizontal axis (A axis) at the bottom front of the lifting component 4, so as to realize the pitch angle adjustment of the carving cutter head 623; Start the rotary motor 4 53, its front output end drives the cutter clamping mechanism 6 to rotate around the vertical axis (C axis) in the middle of the tripod 51, so that the cutter head can cut into the blank from any circumferential angle and avoid carving dead angles;

[0043] Denture blank (y-axis) position matching: While the carving cutter head is being adjusted, the rotary motor 72 of the denture position adjustment component 7 is started, and its output end drives the lead screw 73 to rotate; since the bottom side of the denture carving auxiliary mechanism 8 is rotatably connected to the side wall of the lead screw 73 and the top side is slidably connected to the top side of the worktable support 71, the rotation of the lead screw 73 is converted into linear movement of the denture carving auxiliary mechanism 8 along the y-axis (horizontal longitudinal direction), which drives the blank to be precisely fed towards the carving cutter head. Combined with the x / z axis movement and angle adjustment of the cutter head, a multi-axis linkage alignment of "cutter head-blank" is formed.

[0044] Multi-axis collaborative engraving trajectory execution: After the engraving cutter head and the blank are precisely aligned, the denture CAD design model is imported through the control panel 10, and the engraving program is started: the tool controller 61 drives the engraving cutter head 623 to rotate at the preset speed, and at the same time, each axis drive component moves in coordination according to the design trajectory - the x-axis movement component 3 controls the horizontal movement of the cutter head, the lifting component 4 controls the vertical depth of the cutter head, the tool angle adjustment component 5 adjusts the cutter head angle in real time, and the denture position adjustment component 7 cooperates with the feeding blank. The four links work together synchronously to gradually engrave the blank into the target shape of the denture.

[0045] During the engraving process, the displacement sensor 815 continuously monitors the position of the blank. If there is a slight shift due to factors such as vibration, the data will be fed back to the control panel 10 in real time. The system will automatically fine-tune the position of each axis, correct the engraving trajectory, and avoid the accumulation of processing errors.

[0046] Automatic replacement of engraving cutter head 623: When it is necessary to change tools, a tool change command is sent through the control panel 10: the multi-axis assembly works together to move the tool clamping mechanism 6 above the tool head replacement frame 82, the electric push rod 622 retracts, clamping block one 621 and clamping block two 624 release the old tool, and the old tool falls into the corresponding tool slot of the tool head replacement frame 82; then the engraving head is moved to the tool slot where the new tool is located, the clamping blocks re-clamp the new tool, and the tool change is completed;

[0047] Real-time cleaning of carving dust: The vacuum cleaner 9 uses negative pressure to adsorb ceramic chips and resin dust generated during the carving process, ensuring that dust does not accumulate on the surface of the blank or at the carving tip.
