Its structure includes a milling and turning box, with a servo three-axis milling unit main body located on the right side of the milling and turning box cavity, and a dental prosthesis tooling unit located on the left side of the milling and turning box cavity. The top of the dental prosthesis tooling unit is connected to a dust collection box main body via a suction hose. Multiple tooling tilting arm mechanisms are used on the dental prosthesis tooling unit.

When picking up and putting down materials, the milling and turning part will interfere with the space of the tooling fixture, increasing the difficulty of picking up and putting down materials. In addition, when picking up and putting down materials with the tooling fixture, the dentures can easily fall directly into the collection drawer by accident. Moreover, the collection drawer only has a simple collection function and does not have a suction and guiding function. The processing powder will still be scattered around in the processing box, and the dust will affect the normal use of various mechanisms in the processing box. In order to address the above shortcomings, the present invention proposes a denture milling and turning processing equipment and its working method. Summary of the Invention

[0006] A further improvement is that the milling box includes a box body, an arc-shaped sliding door is fitted on the arc-shaped surface on the left side of the box body, a double door is hinged to the right end of the front side of the box body, an exhaust vent is provided on the left side of the top surface of the box body, and a glass skylight is provided on the right end of the top surface of the box body.

[0007] A further improvement is that the tooling turntable includes a disc body, on which four flip openings are arranged in a cross shape, a motor mounting slot is connected to one side of each of the four flip openings, and a suction tube through-hole is provided on one side of the inner side of each of the four flip openings.

[0008] A further improvement is that the four tooling flipping arm mechanisms include swing arms, on which a servo motor for fixing in a motor mounting slot is drivenly connected, and a fixed clamping seat and a movable clamping seat mechanism for clamping dentures are symmetrically fitted in the opening at the tail of the swing arm, and an iron magnetic suction column is fitted through the middle of the swing arm.

[0009] A further improvement is that a tooling slot is provided in the middle of the tail of the swing arm, and a telescopic sleeve slot is provided on one side of the rear of the tooling slot. The movable clamping mechanism is composed of a telescopic device, a pressure sensor and a movable clamping body, and the fixed clamping body and the movable clamping body are arranged symmetrically.

[0010] A further improvement is that each of the magnetic stabilizing mechanisms includes an L-shaped crossbeam, a second electromagnetic chuck is provided in the middle of the top surface of the L-shaped crossbeam, and a dust collection nozzle is provided at the tail of the L-shaped crossbeam directly below the fixed clamp and the movable clamp body.

The suction tubes are connected to the dust collection nozzles by a suction hose passing through the corresponding suction tube openings. A rigid tube is connected to the center of the top surface of the disc box. A rotating movable joint and a fixed suction tube head are connected to the top surface of the rigid tube. The fixed suction tube head is fitted into the air extraction port.

[0012] Further improvements are made to the fact that the main body of the servo three-axis milling unit, the main body of the dust collection box, the control console, the first electromagnetic chuck, and the second electromagnetic chuck are all existing technologies, and their structures will not be described in detail here.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-9This invention provides a dental prosthesis milling and turning machine and its working method: its structure includes a milling and turning box 1, a servo three-axis milling unit body 2 is arranged on the right side of the cavity of the milling and turning box 1, a dental prosthesis tooling part 3 is arranged on the left side of the cavity of the milling and turning box 1, the top of the dental prosthesis tooling part 3 is connected to a dust collection box body 4 through a suction hose, a control console 5 is arranged in the middle of the front side of the milling and turning box 1, which is electrically connected to the servo three-axis milling unit body 2, the dental prosthesis tooling part 3, and the dust collection box body 4, the dental prosthesis tooling part 3 includes a tooling turntable 31, a servo rotator 32 is drivenly connected to the bottom surface of the tooling turntable 31, and four tooling tilting arm mechanisms 33 are arranged in a cross pattern on the tooling turntable 31. A magnetic stabilizing mechanism 34 is horizontally arranged on one side of the tooling turntable 31. A driven rotating suction tube group 35 is vertically arranged in the middle of the top surface of the tooling turntable 31, which corresponds to and is connected to the four tooling flipping arm mechanisms 33. The other end of the driven rotating suction tube group 35 is connected to the dust collection box body 4 through a suction hose. A first electromagnetic chuck 36 is vertically arranged on one side of the upper end of the four tooling flipping arm mechanisms 33. The servo rotator 32 drives the tooling turntable 31 to rotate 360º back and forth, and the servo rotation angle is 90º each time. When the tooling flipping arm mechanism 33 flips down horizontally, it is electromagnetically attracted and fixed to the magnetic stabilizing mechanism 34. When the tooling flipping arm mechanism 33 flips up vertically, it is electromagnetically attracted and fixed to the first electromagnetic chuck 36.

[0019] The milling and turning box 1 includes a box body 11. An arc-shaped sliding door 12 is fitted on the arc-shaped surface on the left side of the box body 11. A double door 13 is hinged to the right end of the front side of the box body 11. An exhaust vent 14 is provided on the left side of the top surface of the box body 11. A glass skylight 15 is provided on the right end of the top surface of the box body 11.

[0020] The tooling turntable 31 includes a disc body 311, on which four flip openings 312 are arranged in a cross shape. A motor mounting slot 313 is connected to one side of each of the four flip openings 312, and a suction tube through-hole 314 is provided on one side of the inner side of each of the four flip openings 312.

[0021] The four tooling flipping arm mechanisms 33 include a swing arm 331, on which a servo motor 332 is drivenly connected for fixing in the motor mounting slot 313. A fixed clamping seat 333 and a movable clamping seat mechanism 334 for clamping dentures are symmetrically fitted in the tail opening of the swing arm 331. An iron magnetic suction column 335 is through the middle of the swing arm 331.

[0022] The tail of the swing arm 331 has a tooling slot 3311 in the middle, and a telescopic sleeve slot 3312 is connected to the rear side of the tooling slot 3311. The movable clamping mechanism 334 is composed of a telescopic device 3341, a pressure sensor 3342 and a movable clamping body 3343. The fixed clamping body 333 and the movable clamping body 3343 are symmetrically arranged.

[0023] Each of the magnetic stabilizing mechanisms 34 includes an L-shaped crossbeam 341, a second electromagnetic chuck 342 is provided in the middle of the top surface of the L-shaped crossbeam 341, and a dust collection nozzle 343 is provided at the tail of the L-shaped crossbeam 341 directly below the fixed clamp 333 and the movable clamp body 3343.

[0024] The driven rotating suction tube assembly 35 includes a disc box 351, on which multiple suction tubes 352 are connected in a circular array. The suction tubes 352 and the dust collection nozzle 343 are connected by a suction hose passing through the corresponding suction tube opening 314. A rigid tube 353 is connected to the center of the top surface of the disc box 351. A rotating movable joint 354 and a fixed suction tube head 355 are connected to the top surface of the rigid tube 353. The fixed suction tube head 355 is fitted into the air extraction port 14.

[0025] Working principle: When clamping the denture, first open the arc-shaped sliding door 12. At this time, a tooling flipping arm mechanism 33 will rotate forward and then flip vertically through the tooling flipping arm mechanism 33. The first electromagnetic chuck 36 and the iron magnetic suction column 335 are then electromagnetically attracted, so that the fixed clamp 333 and the movable clamp mechanism 334 face upward and away from the dust collection nozzle 343. Then, the denture is clamped between the fixed clamp 333 and the movable clamp mechanism 334 for fixation. Then, the tooling flipping arm mechanism 33 flips horizontally, so that the iron magnetic suction column 335 and the second electromagnetic chuck 342 are re-established electromagnetic connection and fixed.

[0026] The 90º rotation of the tooling tilting arm mechanism 33 is achieved by the servo motor 332 driving the swing arm 331 to servo swing. The servo motor 332 only acts as a drive and does not provide strong stability for the swing arm 331 in the lateral and vertical directions. Therefore, the electromagnetic adsorption connection between the first electromagnetic chuck 36 and the iron magnetic column 335 can stabilize the vertical direction of the swing arm 331. In particular, the electromagnetic adsorption connection between the iron magnetic column 335 and the second electromagnetic chuck 342 is very important for strengthening the horizontal fixation of the swing arm 331, so that there will be no shaking problem when the tooling tilting arm mechanism 33 clamps the denture and performs milling on the main body 2 of the servo three-axis milling unit.

[0027] When the telescopic device 3341 on the movable clamping mechanism 334 drives the movable clamping body 3343 to cooperate with the fixed clamping seat 333 to clamp the denture, the pressure sensor 3342 assists in sensing the clamping strength, so that the clamping effect of the denture can be consistent each time, thereby improving the clamping effect of the tooling on the denture.

[0028] In addition, the tooling tilting arm mechanism 33 adopts vertical tilting for picking up and putting down materials. First, the upward angle makes it easier to operate, and second, it can be kept away from the dust collection nozzle 343 to prevent dentures from falling into the dust collection nozzle 343 and being sucked away.

[0029] Another dust collection nozzle 343 is designed to correspond to a tooling tilting arm mechanism 33, which can continuously vacuum each tooling tilting arm mechanism 33, so that the powder generated during machining in the milling box 1 will not fall onto each tooling tilting arm mechanism 33. Compared with the dust collection nozzle 343, which is fixedly mounted on the bottom of the milling part of the servo three-axis milling part body 2, the dust collection effect of important mechanisms is better.

[0030] The function of the driven rotating suction tube assembly 35 is that when the tooling turntable 31 reciprocates and rotates, the disc box 351 and the rigid tube 353 rotate accordingly, while the rotating movable joint 354 prevents the fixed suction tube head 355 from being driven to rotate together.

[0031] When a tooling tilting arm mechanism 33 rotates 90º to align with the servo three-axis milling unit body 2, the servo three-axis milling unit body 2 uses programmed positioning to perform milling operations on the dentures on the tooling tilting arm mechanism 33. The powder generated during milling is sucked away by the corresponding dust collection nozzle 343. After a new tooling tilting arm mechanism 33 rotates forward to the corresponding position, a new round of denture clamping and waiting begins.

[0032] During the milling and turning process, the dust collection box body 4 is activated, allowing powder to be sucked into the dust collection box body 4 through the connection of the dust collection nozzle 343, multiple suction hoses, suction pipe 352, disc box 351, rigid pipe 353, rotary joint 354, and fixed suction head 355.

[0033] During milling and turning, the glass sunroof 15 serves as an observation port for the machining status, while the double door 13 is used for changing tools in the main body 2 of the servo three-axis milling unit, and the arc-shaped sliding door 12 is used for loading and unloading materials after each tooling tilting arm mechanism 33 rotates forward.

[0034] Furthermore, the servo milling machining method of the main body 2 of the servo three-axis milling unit is existing technology, and will not be elaborated on here.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
