[0001] This invention relates to the field of milling machine structure technology, and in particular to a high-precision five-axis linkage dental prosthesis milling machine. Background Technology

[0002] Dental prostheses (artificial teeth) are an important component of the field of oral prosthetics, widely used for functional reconstruction and aesthetic restoration of patients with tooth defects or missing teeth. With the increasing aging population and growing awareness of oral health, the demand for personalized, high-precision, and efficient denture manufacturing is increasing. Currently, denture manufacturing methods mainly include traditional hand casting, CAD / CAM digital cutting, and 3D printing. Among these, CAD / CAM-based CNC milling technology has become the mainstream method for denture manufacturing due to its advantages such as high processing precision, wide material adaptability, and good surface quality.

[0003] In CNC milling and engraving equipment, five-axis linkage machining technology is widely used in the manufacture of complex structural components such as dentures, crowns, bridges, and implant abutments because it can continuously process workpieces from multiple angles and on complex curved surfaces in a single setup. Compared to traditional three-axis or four-axis equipment, five-axis linkage milling and engraving machines have better tool accessibility and surface adaptation capabilities, which can significantly improve the morphological accuracy and surface finish of dentures.

[0004] Traditional five-axis linkage engraving and milling equipment mostly uses dust collection devices for dust prevention. When the dust collection screen is worn out, the bolts need to be removed and replaced, which is inconvenient to use. Summary of the Invention

[0005] The purpose of this invention is to provide a high-precision five-axis linkage dental engraving and milling equipment, which aims to solve the problem that the dust collection screen of traditional engraving and milling equipment needs to be disassembled and replaced after dust collection, which is inconvenient to use.

[0006] To achieve the above objectives, the present invention provides a high-precision five-axis linkage dental prosthesis carving and milling equipment, including a five-axis carving and milling machine and a water-cooled dustproof assembly. The water-cooled dustproof assembly includes a water tank, a drain pipe, a spray gun, a guide channel, a filter tank, and a drain pipe. The water tank is fixedly connected to the five-axis carving and milling machine and is located on one side of the machine. The drain pipe is connected to the water tank and is located on one side of the tank. The spray gun is detachably connected to the drain pipe and is located on the side of the drain pipe away from the water tank. The guide channel is fixedly connected to the five-axis carving and milling machine and is located at the bottom of the machine. The filter tank is slidably connected to the guide channel and penetrates the channel. The drain pipe is connected to the guide channel and is located at the bottom of the channel.

[0007] The drainage pipe includes a liquid pump and a guide pipe. The liquid pump is fixedly installed on the outside of the water storage tank. The guide pipe is connected to the liquid pump and the spray gun, and is located between the spray gun and the liquid pump.

[0008] The spray gun includes a spray gun body and a connector. The connector is connected to the guide pipe and is located on the side of the guide pipe away from the liquid pump. The spray gun body is fixedly connected to the connector and is located on the side of the connector away from the guide pipe.

[0009] The filter tank includes a sliding groove, a filter screen, and a sealing ring. The sliding groove is slidably connected to and passes through the flow guide groove. The filter screen is fixedly disposed at the bottom of the sliding groove, and the sealing ring is fixedly disposed on the outside of the sliding groove.

[0010] The filter tank further includes a rotating head and a pressure strip. The rotating head is rotatably connected to the flow guide channel and is located outside the flow guide channel. The pressure strip is fixedly connected to the rotating head and is located on the rotating head.

The sensor-activated water replenishment module is located inside the tank body.

[0012] The sensing water replenishment module includes a water level sensing unit and a water replenishment on / off unit. The water level sensing unit is used to sense the water level inside the water tank in real time and transmit the sensed data to the water replenishment switch unit. The water replenishment interruption unit determines whether to interrupt the water inlet pipe of the water tank body to replenish water based on the sensing data.

[0013] This invention discloses a high-precision five-axis linkage dental prosthesis carving and milling machine. The five-axis carving and milling machine is used for carving and milling dental prostheses. During the carving and milling process, a water-cooled dust-proof assembly sprays water onto the carving area to remove dust. Specifically, the water tank stores clean water / cutting fluid. The liquid is transported to the spray gun through the guide pipe, and the spray gun then sprays the liquid towards the carving area for dust removal. Wastewater falls into the guide channel below the spray gun due to gravity, and the guide channel quickly directs the wastewater to the filter tank. The filter tank filters out the dust, and the filtered wastewater passes through the filter tank into the drain pipe and is discharged. This equipment adopts a sliding filter tank + water-cooled wet dust collection structure, eliminating the need for bolt fastening. The filter tank and the guide channel are in sliding contact, with no fasteners. Cleaning and replacement can be done simply by pulling the filter tank, completely eliminating the need to remove bolts.

Detailed Implementation

[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0021] Please see Figures 1 to 4 This invention provides a high-precision five-axis linkage dental prosthesis carving and milling equipment, including a five-axis carving and milling machine 1 and a water-cooled dustproof assembly. The water-cooled dustproof assembly includes a water tank, a drain pipe, a spray gun, a guide channel 2, a filter tank, and a drain pipe 3. The water tank is fixedly connected to the five-axis carving and milling machine 1 and is located on one side of the machine. The drain pipe is connected to the water tank and is located on one side of the tank. The spray gun is detachably connected to the drain pipe and is located on the side of the pipe away from the water tank. The guide channel 2 is fixedly connected to the five-axis carving and milling machine 1 and is located at the bottom of the machine. The filter tank is slidably connected to the guide channel 2 and penetrates the channel. The drain pipe 3 is connected to the guide channel 2 and is located at the bottom of the channel.

[0022] In this embodiment, the five-axis engraving and milling machine 1 is used for engraving and milling dentures. During the denture engraving and milling process, water is sprayed onto the engraving and milling area of ​​the denture through the water-cooled dust-proof assembly. Specifically, the water tank is composed of a water tank body 13, which stores clean water / cutting fluid. The liquid is transported to the spray gun through the guide pipe, and the spray gun then sprays the liquid toward the engraving and milling area of ​​the denture for dust prevention. The wastewater falls into the guide trough 2 below the spray gun due to gravity, and the guide trough 2 then quickly guides the wastewater to the filter tank. After passing through the filter tank... The filtered wastewater passes through the filter tank and enters the drain pipe 3, from where it is discharged. This equipment adopts a sliding filter tank + water flow wet dust collection structure that eliminates the need for bolt fastening. The filter tank and the guide channel 2 are in sliding fit without fasteners. Daily dust cleaning and filter screen replacement can be completed by simply pulling out the filter tank, completely eliminating the tedious operation of disassembling and tightening bolts. This greatly improves the convenience of equipment maintenance and solves the problem of inconvenience caused by the need to disassemble bolts and replace the dust screen after it has been collected in traditional engraving and milling equipment.

[0023] Furthermore, the drainage pipe includes a liquid pump 4 and a guide pipe 5. The liquid pump 4 is fixedly installed on the outside of the water storage tank. The guide pipe 5 is connected to the liquid pump 4 and the spray gun, and is located between the spray gun and the liquid pump 4.

[0024] In this embodiment, the liquid pump 4 is fixedly installed on the outer wall of the water tank body 13, without occupying the internal water storage space of the water tank body 13, and at the same time facilitating the later inspection and maintenance of the equipment. The water inlet of the liquid pump 4 is connected to the inside of the water tank body 13, and can draw clean water or cutting fluid stored in the water tank body 13. The water outlet is connected to the guide pipe 5. The liquid pump 4 provides a stable water supply pressure, and continuously and quantitatively delivers the liquid into the guide pipe 5. The guide pipe 5 adopts a corrosion-resistant hose structure, which can be flexibly arranged according to the processing point of the five-axis engraving and milling machine 1, and accurately connects to the spray gun to ensure smooth liquid delivery and avoid water delivery jamming and leakage problems.

[0025] Furthermore, the spray gun includes a spray gun body 6 and a connector 7. The connector 7 is connected to the guide pipe 5 and is located on the side of the guide pipe 5 away from the liquid pump 4. The spray gun body 6 is fixedly connected to the connector 7 and is located on the side of the connector 7 away from the guide pipe.

[0026] In this embodiment, the connector 7 is used for docking the spray gun body 6 and the guide tube 5, facilitating the later maintenance and replacement of the spray gun body 6. The spray gun body 6 is directly facing the dental prosthesis processing area of ​​the five-axis engraving and milling machine 1, precisely covering the engraving and milling cutting points, ensuring that dust settles immediately, and simultaneously cooling and lubricating the high-speed machining tools and dental prosthesis blanks, reducing machining wear and workpiece thermal deformation, and improving the dental prosthesis processing accuracy.

[0027] Furthermore, the filter tank includes a sliding groove 8, a filter screen 9, and a sealing ring 10. The sliding groove 8 is slidably connected to the guide groove 2 and passes through the guide groove 2. The filter screen 9 is fixedly disposed at the bottom of the sliding groove 8, and the sealing ring 10 is fixedly disposed on the outside of the sliding groove 8. The filter tank also includes a rotating head 11 and a pressure strip 12. The rotating head 11 is rotatably connected to the guide groove 2 and is located on the outside of the guide groove 2. The pressure strip 12 is fixedly connected to the rotating head 11 and is located on the rotating head 11.

[0028] In this embodiment, the sliding groove 8 precisely engages with the inner side of the guide groove 2, enabling pull-out sliding assembly and disassembly without fastener limitations, facilitating convenient operation. The filter screen 9 uses high-density microporous filter material, effectively intercepting solid impurities such as denture dust, metal shavings, and grinding residue in the wastewater, achieving solid-liquid separation and preventing impurities from entering the drain pipe 3 and causing blockage. The sealing ring 10 covers the outer wall of the sliding groove 8. After the sliding groove 8 is fully pushed into the guide groove 2, it fills the gap between the sliding groove 8 and the guide groove 2, preventing dust-laden wastewater from leaking through the gap and ensuring that all wastewater is filtered by the filter screen 9. The rotating head 11 and the pressure strip 12 form a limiting auxiliary structure. During normal operation, the rotating head 11 drives the pressure strip 12 to rotate to the outside of the sliding groove 8, pressing and limiting the sliding groove 8 to prevent the filter tank from shifting or falling off due to equipment vibration. When it is necessary to clean impurities, simply rotate the rotating head 11 to drive the pressure strip 12 out of the limiting state, and the sliding groove 8 can be pulled directly, which takes into account both operational stability and maintenance convenience.

[0029] Furthermore, the water tank includes a tank body 13 and a sensing water replenishment module 14. The tank body 13 is fixedly connected to the five-axis CNC engraving machine 1 and is located on one side of the five-axis CNC engraving machine 1. The sensing water replenishment module 14 is disposed inside the tank body 13. The sensing water replenishment module 14 includes a water level sensing unit 15 and a water replenishment interruption unit 16. The water level sensing unit 15 is used to sense the water level in the tank body 13 in real time and transmit the sensed data to the water replenishment interruption unit 16. The water replenishment interruption unit 16 determines whether to interrupt the water inlet pipe of the tank body 13 to replenish water based on the sensed data.

[0030] In this embodiment, the water tank body 13 is a sealed water storage structure used to store clean water or cutting fluid required for spray dust removal, providing a continuous water supply for the water-based dust suppression system. The sensing water replenishment module 14 realizes automated monitoring and water replenishment control of the water tank level, eliminating the need for manual real-time monitoring. The water level sensing unit 15 can collect real-time water level data inside the water tank body 13, accurately identify high and low water level thresholds, and transmit real-time sensing electrical signals to the water replenishment interruption unit 16. When the water level sensing unit 15 detects that the water level inside the water tank body 13 is lower than a set minimum threshold, the water replenishment interruption unit 16 automatically opens the water inlet pipe to initiate automatic water replenishment; when the water level rises to a set maximum threshold, the water replenishment interruption unit 16 automatically cuts off the water replenishment path, stopping water replenishment. This structure can maintain the water level inside the water tank body 13 within the standard operating range, avoiding water supply interruption and dust removal failure due to excessively low water levels, or overflow problems due to excessively high water levels.

[0031] The above-disclosed embodiments are merely preferred embodiments of a high-precision five-axis linkage dental prosthesis milling device of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
