Description

Technical Field

[0001] The utility model relates to the technical field of artificial tooth processing fixing frames, in particular to a fixing frame used for artificial tooth processing. Background Art

[0002] Dentures are artificial teeth devices used to replace missing teeth. When people lose one or more teeth, they can choose to use dentures to restore chewing function and aesthetics. Existing dentures are generally made of zirconia ceramic blocks carved and milled on dental engraving and milling machines. When using the engraving and milling machine to engrave and mill the zirconia ceramic block, it is necessary to use a fixing frame to fix the zirconia ceramic block to prevent the position of the zirconia ceramic block from moving, so as to facilitate the engraving and milling of the zirconia ceramic block by the engraving and milling machine. The general fixing frame includes a spindle, a connecting arm, a motor, a fixing clamp and a fixing block. When in use, the staff places the zirconia ceramic block in the fixing groove on the fixing clamp, and then uses bolts to tighten the fixing block and the fixing clamp to fix the zirconia ceramic block. The spindle, rotating motor, etc. can be used to realize multi-angle rotation of the zirconia ceramic block, thereby improving the efficiency of engraving and milling.

[0003] The patent with the current publication number CN219726835U discloses a clamping and positioning structure of a denture engraving and milling machine, including a positioning seat, a positioning assembly and a clamping body for clamping a zirconium disc, the positioning assembly is installed in the positioning seat, and the clamping body can be plugged and positioned in the positioning assembly; a vent is provided on the side wall of the positioning seat; the positioning assembly includes a seat body, a piston, a spring, a cover body and a steel ball, the piston, the cover body and the inner wall of the positioning seat together form an air cavity, and the air cavity is connected to the vent; the clamping body includes a fixture seat and a positioning rivet, a positioning rivet is fixed in the middle of the fixture seat, and an annular arc groove is provided on the side wall of the positioning rivet, the positioning rivet can pass through the insertion hole and extend into the stop hole, and the steel ball is stuck in the annular arc groove.

Since the existing zirconia ceramic block fixing frame cannot clean the dust, the dust may enter the joints of the fixing frame, affecting the rotation of the fixing frame, resulting in the fixing frame being unable to accurately adjust the position of the zirconia ceramic block, thereby reducing the quality of the denture product. The dust will also increase the wear and friction of the fixing frame during use, resulting in a reduced service life of the fixing frame. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] like Figures 1 to 5 As shown, a fixed frame for denture processing includes a rotating motor 1, a fixed shell 2 is fixedly connected to the surface of the rotating motor 1, a suction bin 3 is fixedly connected to the middle of the fixed shell 2, a suction assembly is connected inside the suction bin 3, the suction assembly includes two connecting frames 4, a rotating shaft 5 and a fan 6, the connecting frame 4 is fixedly connected to the inner wall of the suction bin 3, the rotating shaft 5 is rotatably connected to the middle of the connecting frame 4, the fan 6 is sleeved on the outer wall of the middle of the rotating shaft 5, the fan 6 is located between the two connecting frames 4, the inner wall of the fixed shell 2 is connected to a driving assembly, an air outlet 11 is opened at one end of the fixed shell 2, an air inlet 12 is opened at the other end of the fixed shell 2, and an air guide 13 is sleeved on the outer wall of the air outlet 11.

[0024] like Figure 1 As shown, a fixing frame for denture processing in the utility model is similar to the existing fixing frame structure for denture processing, such as the clamping and positioning structure of the denture engraving and milling machine disclosed in the patent with publication number CN219726835U. The main improvement of the utility model is that the fixing frame can clean the dust generated by the engraving and milling process, such as Figures 1 to 5As shown, when a fixing frame for denture processing in the utility model is in use, after the staff installs the zirconia ceramic block on the fixing frame, during the engraving and milling process of the engraving and milling machine, the driving component will drive the rotating shaft 5 and the fan 6 to rotate, and the fan 6 will inhale air from the air inlet 12 during the rotation process. After the air is accelerated by the fan 6, it will enter the air duct 13 from the air outlet 11, and then be sprayed to the surface of the zirconia ceramic block by the air duct 13, so as to blow away the dust generated during the engraving and milling process on the surface of the zirconia ceramic block, thereby preventing the dust from entering the joint of the fixing frame; the fixing shell 2 and the air suction bin 3 are welded and fixed, and the fixing shell 2 and the rotating motor 1 can be welded, bolted, bonded or other methods; the cross-sectional area of ​​the air suction bin 3 is larger than that of the fixing shell 2. Compared with placing the fan 6 in the fixing shell 2, the air suction bin 3 can increase the size of the fan 6, thereby improving the air suction capacity of the fan 6 and enhancing the blowing force on the dust; the connecting frame 4 can provide fixation for the rotating shaft 5 and the fan 6.

[0025] By arranging a fan 6 in the air suction bin 3 and an air duct 13 on the air outlet 11, the air duct 13 cooperates with the fan 6 so that the air duct 13 can spray a high-speed airflow to the surface of the zirconia ceramic block, and the high-speed airflow is used to carry away the dust on the surface of the zirconia ceramic block, thereby reducing the risk of dust entering the fixed frame, increasing the service life of the fixed frame, and improving the accuracy of the fixed frame in adjusting the position of the zirconia ceramic block, thereby improving the product quality of the denture.

[0026] like Figure 3 and Figure 4 As shown, the driving assembly includes a driven wheel 7, a driving wheel 8, a driving motor 9 and a fixed block 10. The driven wheel 7 is fixedly connected to one end of the rotating shaft 5 close to the air inlet 12, the fixed block 10 is fixedly connected to the bottom surface of the inner wall of the fixed shell 2, the driving motor 9 is fixedly connected to the fixed block 10, the driving wheel 8 is fixedly connected to the output end of the driving motor 9, and the driving wheel 8 is meshed with the driven wheel 7.

[0027] Specifically, the driving motor 9 will drive the driving wheel 8 to rotate, the driving wheel 8 will drive the driven wheel 7 to rotate, and the driven wheel 7 will then drive the rotating shaft 5 and the fan 6 to rotate, thereby realizing the air suction capability; the flowing air will take away the heat of the driving motor 9, thereby improving the stability of the driving motor 9 during operation and increasing the service life of the driving motor 9.

[0028] like Figure 3 and Figure 5 As shown, a cloth bag 15 is fixedly connected to the air inlet 12 .

[0029] Specifically, the cloth bag 15 can filter the air entering the air inlet 12 to prevent dust from entering the fixed shell 2 and the air suction bin 3, thereby reducing the wear and friction of the fan 6 and the drive motor 9 and increasing the service life of the fan 6 and the drive motor 9.

[0030] like Figure 5 As shown, a support frame 16 is slidably connected inside the cloth bag 15 , and a connecting plate 17 is fixedly connected to one side of the support frame 16 .

[0031] Specifically, the support frame 16 can shape the cloth bag 15 so that the inner wall of the cloth bag 15 is not easily folded, and the air is in full contact with the surface of the cloth bag 15, thereby improving the stability and practicality of the cloth bag 15.

[0032] like Figure 5 As shown, a connection groove 18 is opened on one side of the fixed shell 2, and a magnetic block 19 is fixedly connected in the connection groove 18, and the position of the magnetic block 19 corresponds to that of the connection plate 17.

[0033] Specifically, the connecting plate 17 is made of iron material, and the connecting plate 17 is adsorbed by the magnetic block 19, which can provide fixation for the support frame 16 and the cloth bag 15; when the cloth bag 15 has been used for a long time, the staff can separate the connecting plate 17 from the magnetic block 19, pull out the support frame 16, and then remove the cloth bag 15 to replace and clean the cloth bag 15. This arrangement facilitates the staff to replace and clean the cloth bag 15, improves the stability of the support frame 16, and ensures that the support frame 16 and the cloth bag 15 are located in the center of the fixed shell 2.

[0034] like Figure 1 and Figure 2 As shown, the air guide pipe 13 is a universal tube.

[0035] Specifically, the air duct 13 provided in the universal tube can facilitate the staff to adjust the position of the air duct 13 and accurately clean different positions on the surface of the zirconia ceramic block, thereby improving the dust cleaning effect and improving the practicality and applicability of the air duct 13.

[0036] like Figure 1 and Figure 2 As shown, one end of the air guide tube 13 is fixedly connected to a nozzle 14 , and the diameter of the nozzle 14 is smaller than the diameter of the air guide tube 13 .

[0037] Specifically, the nozzle 14 can pressurize the air in the air duct 13 to increase the impact force of the air in the air duct 13, thereby further improving the cleaning effect of the dust on the surface of the zirconia ceramic block. The small diameter of the nozzle 14 helps to generate a more concentrated jet airflow, making the cleaning process more efficient.

[0038] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention.
