Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis processing technology, specifically a multi-scale structural trimming and positioning device for nano-ceramic dentures. Background Technology

[0002] Nano-porcelain dentures are dental restorations made from nanoscale materials. A multi-scale structural adjustment and positioning device for nano-porcelain dentures is a specialized device used to clamp and position the denture during processing or restoration. Existing positioning devices allow for grinding of the denture after it has been fixed in place. However, when grinding other surfaces after one surface is finished, the positioning mechanism must be released, the denture flipped over, and then fixed again before grinding can continue. This frequent fixing and unfixing of the positioning mechanism reduces processing efficiency. The positioning mechanism for denture processing, as described in announcement number CN221436026U, controls the rotation of the clamping mechanism through a snap-fit ​​mechanism. After fixing the denture, the processing surface can be changed without releasing the clamp, reducing time spent on the positioning mechanism and improving processing efficiency.

[0003] While the aforementioned technology can modify the processing surface of dentures without removing the fixation, it has the problem of not being able to clean up the dust generated during denture processing. The denture grinding, polishing, and plaster model trimming processes generate a large amount of ceramic powder, resin powder, and metal oxide dust. If not cleaned for a long time, the dust concentration will exceed the limit. Long-term inhalation of this dust can damage the lungs of workers, and the dust can also obstruct vision, making it impossible to control the amount of trimming. Utility Model Content

[0004] The purpose of this invention is to provide a multi-scale structural adjustment and positioning device for nano-ceramic dentures, in order to solve the problem mentioned in the background art that the positioning devices currently on the market cannot clean the dust generated during denture processing after clamping and positioning the denture.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-scale structural adjustment and positioning device for nano-ceramic dentures, comprising a processing table, a first support plate fixedly connected to one end of the top of the processing table, a drive motor installed in the upper middle part of the first support plate, a rotating fan provided at the output end of the drive motor, second support plates provided at both ends of the top of the processing table, a rotating shaft rotatably connected between the two second support plates, an air guide plate fixedly connected to the outer surface of the rotating shaft, a gear provided at one end of the rotating shaft, a rack slidably connected inside one of the second support plates and meshing with the gear, a drive assembly for moving the rack on the second support plate, a dust suction assembly for absorbing dust on the top of the processing table, and a positioning assembly for clamping and positioning the denture on the top of the processing table.

[0006] Preferably, the drive assembly includes two fixed plates respectively disposed at both ends of a second support plate, and a reciprocating screw threaded inside a rack is rotatably connected between the two fixed plates. One end of the reciprocating screw is connected to a rotating column, and one end of the rotating column and one end of the rotating fan are connected by a first synchronous belt.

[0007] Preferably, the dust collection assembly includes a dust collection fan installed at the bottom of the processing table, a dust filter bag at the output end of the dust collection fan, a flexible hose at the input end of the dust collection fan, a dust collection pipe at the end of the flexible hose away from the dust collection fan, and a dust collection hood at the end of the dust collection pipe away from the flexible hose.

[0008] Preferably, the top of the processing table is provided with a third support plate at both ends. The upper part of each of the two third support plates is rotatably connected with a rotating rod, and one end of each rotating rod is connected to both sides of the dust suction pipe. The end of one rotating rod away from the dust suction pipe is connected to one end of the rotating shaft through a second synchronous belt.

[0009] Preferably, the positioning component includes a fixed ring disposed on the top of the processing table, and a movable ring is slidably connected to the top of the processing table. The fixed ring and the movable ring are both connected to clamping rings by springs on the sides of each other.

[0010] Preferably, both ends of the fixed ring and the movable ring are provided with connecting plates, and a locking screw is rotatably connected inside the connecting plate located on one side of the fixed ring, and the locking screw is threadedly connected inside the connecting plate on one side of the movable ring.

[0011] Preferably, a limiting rod is provided inside the connecting plate on the other side of the fixed ring, and the limiting rod is slidably connected inside the connecting plate on the other side of the moving ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] The rotating fan, driven by a motor, blows away the dust generated during denture processing. The directional airflow generated by the fan can blow away suspended dust in real time, preventing it from adhering to the denture surface, mold, or processing tools, ensuring a clear view and reducing finishing errors caused by dust obstruction.

[0014] The drive components are designed to drive the rotating shaft and the air intake plate to swing, allowing the air to be directed to different positions of the denture. Dentures have complex structures such as depressions and gaps, and it is difficult to blow away dust in dead corners with a fixed air direction. The swinging of the air intake plate can adjust the air delivery angle and direct the airflow to different areas, avoiding dust residue in micro-pits and ensuring the cleanliness of the entire surface.

[0015] The dust-collecting components effectively absorb dust floating in the air and on the surface of the processing table, preventing suspended dust from flying or adhering to the surface of dentures, and also reducing the probability of workers inhaling it. Attached Figure Description

Detailed Implementation

[0023] 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.

[0024] This utility model provides the following technical solution: a multi-scale structural adjustment and positioning device for nano-ceramic dentures.

[0025] Example 1: To address the problem that existing positioning devices cannot clean the dust generated during denture processing after clamping and positioning the denture, the following solution is disclosed: a processing table 1, with a first support plate 2 fixedly connected to one end of the top of the processing table 1, a drive motor installed in the upper middle part of the first support plate 2, and a rotary fan 3 (e.g., ...) at the output end of the drive motor. Figures 1-4 As shown), the top of the processing table 1 is provided with second support plates 4 at both ends, and a rotating shaft 5 is rotatably connected between the two second support plates 4 (as shown). Figures 4-6 As shown), a fan plate 6 is fixedly connected to the outer surface of the rotating shaft 5 to guide the airflow. A gear 10 is provided at one end of the rotating shaft 5, and a rack 9 (as shown) is slidably connected inside a second support plate 4 and meshes with the gear 10. Figure 6 As shown), the second support plate 4 is equipped with a drive assembly for moving the rack 9, and the top of the processing table 1 is equipped with a dust-collecting assembly for absorbing dust. The drive assembly includes two fixed plates respectively disposed at both ends of a second support plate 4, and a reciprocating screw 8 threaded inside the rack 9 is rotatably connected between the two fixed plates. One end of the reciprocating screw 8 is connected to a rotating column, and one end of the rotating column and one end of the rotary fan 3 are connected by a first synchronous belt (e.g., ...). Figure 1 , Figure 3 , Figure 4 and Figure 6 (As shown), the dust collection assembly includes a dust collection fan 11 installed at the bottom of the processing table 1. The output end of the dust collection fan 11 is equipped with a dust filter bag 12 for filtering dust. The input end of the dust collection fan 11 is equipped with a flexible hose 13. The end of the flexible hose 13 away from the dust collection fan 11 is connected to a dust collection pipe 14. The end of the dust collection pipe 14 away from the flexible hose 13 is equipped with a dust collection hood 15. Third support plates 16 are also provided at both ends of the top of the processing table 1. Rotating rods 17 are rotatably connected to the upper parts of both third support plates 16. One end of each rotating rod 17 is connected to both sides of the dust collection pipe 14, and the end of one rotating rod 17 away from the dust collection pipe 14 is connected to one end of the rotating shaft 5 via a second synchronous belt (e.g., ...). Figures 1-3 (As shown).

[0026] The denture to be processed is placed on top of the processing table 1. The operator then trims it. During trimming, the drive motor can be activated to rotate the rotary fan 3, which then generates a directional airflow directed towards the processing area (e.g., ...). Figures 1-4 As shown), the dust generated during polishing and finishing is removed from the denture surface, and some of the suspended dust is blown onto the surface of the processing table 1 or into the air. Then, the vacuum fan 11 is turned on, which draws the dust into the dust bag 12 through the vacuum hood 15 and the vacuum pipe 14 (as shown). Figure 2 and Figure 3 As shown), when the rotary fan 3 rotates, it also drives the rotating column to rotate under the action of the first synchronous belt, which in turn drives the reciprocating screw 8 to rotate, thereby causing the rack 9 to slide back and forth inside the second support plate 4. Subsequently, under the action of the gear 10, it drives the rotating shaft 5 to rotate back and forth, which in turn drives the air guide plate 6 to rotate back and forth. Then the air guide plate 6 adjusts the airflow guidance angle to ensure that the airflow can cover the complex structure of the denture and avoid dust residue in dead corners. When the rotating shaft 5 rotates, it also drives the rotating rod 17 to rotate under the action of the second synchronous belt (as shown). Figures 1-3 As shown in the figure, this causes the suction pipe 14 and the suction hood 15 to swing back and forth, thereby increasing the suction range and improving the suction effect.

[0027] Example 2: Unlike Example 1, the positioning component can clamp and position the denture. It is disclosed that: the top of the processing table 1 is also provided with a positioning component for clamping and positioning the denture. The positioning component includes a fixing ring 18 (e.g., a retaining ring 18) disposed on the top of the processing table 1. Figures 1-3 As shown), a movable ring 7 is slidably connected to the top of the processing table 1. Clamping rings 19 are connected to the sides of the fixed ring 18 and the movable ring 7 near each other via springs, used to clamp the denture. Connecting plates 20 are provided at both ends of the fixed ring 18 and the movable ring 7. Locking screws (such as...) are rotatably connected inside the connecting plate 20 located on the side of the fixed ring 18. Figures 1-3 As shown), the locking screw is threadedly connected to the inside of the connecting plate 20 on one side of the moving ring 7, and a limiting rod is provided inside the connecting plate 20 on the other side of the fixed ring 18, and the limiting rod is slidably connected to the inside of the connecting plate 20 on the other side of the moving ring 7.

[0028] After placing the denture between the two clamping rings 19, the locking screw can be turned, which, under the action of the limiting rod, causes the moving ring 7 to move (e.g., Figures 1-3 As shown), and gradually approach the fixing ring 18, then the clamping ring 19 first contacts the surface of the denture, and continuing to tighten the locking screw will compress the spring, using the elastic force of the spring to apply a flexible clamping force to the denture, thereby adapting to dentures of different sizes.

[0029] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.
