[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 、 Figure 2 and Figure 3, An embodiment provided by the present utility model: A positioning device for fixed denture production, including a base 1. A L-shaped plate 3 is fixedly connected to the top of the base 1. A working box 4 is fixedly connected to the top of the L-shaped plate 3. A first groove 5 is provided on the front side of the working box 4. Threaded rods 6 are rotatably connected to both the left and right sides of the first groove 5. The adjacent ends of the two threaded rods 6 penetrate through the first groove 5 and are threadedly connected to a moving block 7. An expansion rod 8 is fixedly connected to the front side of the two moving blocks 7. The front ends of the two expansion rods 8 are fixedly connected to an extension plate 9. Fixed rods 10 are fixedly connected to the front sides of the tops of the two extension plates 9. A fixed ring 11 is fixedly connected to the outer wall of the fixed rod 10. A fixing plate 12 is fixedly connected to the top of the working box 4. A second groove 13 is provided on the front side of the fixing plate 12. Springs 14 are fixedly connected to both the left and right sides inside the second groove 13. The front ends of the two springs 14 are fixedly connected to the same limiting plate 15. A dust suction mechanism 2 is provided on the left side of the base 1, and the dust suction mechanism 2 is used for dust suction;

[0032] Specifically, by rotating the threaded rod 6, the moving block 7 is displaced, driving the extension plate 9 and the fixed rod 10 to move accordingly. According to the actual situation of the denture, the fixed rod 10 is adjusted accordingly. At the same time, the switch 16 is activated to make the expansion rod 8 perform a contraction operation, and the denture is clamped in cooperation with the fixed rod 10 and the limiting plate 15. The spring 14 will retract due to being squeezed, effectively preventing damage to the denture caused by excessive clamping force. The clamping device can be directly adjusted, which can improve work efficiency.

[0033] Refer to Figure 2 and Figure 3 , The dust suction mechanism 2 includes a U-shaped frame 201. The U-shaped frame 201 is fixedly connected to the left side of the L-shaped plate 3. A dust suction head 202 is slidably connected to the U-shaped frame 201. A dust suction pipe 203 is connected to the bottom of the dust suction head 202. A dust storage groove 204 is provided on the front side of the top of the base 1. An air inlet 205 is provided on the left side of the dust storage groove 204. A vacuum cleaner 206 is fixedly connected to the left side of the base 1. The output end of the vacuum cleaner 206 penetrates through the air inlet 205, and the input end of the vacuum cleaner 206 is connected to one end of the dust suction pipe 203;

[0034] Specifically, a certain amount of debris will be generated after grinding. Some of the debris will fall into the dust storage groove 204, and there is still some debris that may be scattered in other areas of the equipment. At this time, first remove the dust suction head 202 from the U-shaped frame 201, and at the same time operate the switch 16 to start the vacuum cleaner 206. The vacuum cleaner 206 will effectively suck the debris scattered on the equipment through the dust suction pipe 203 and the dust suction head 202, and introduce the debris into the dust storage groove 204 through the air inlet 205, facilitating the staff to clean the debris.

[0035] Refer to Figure 1 and Figure 2, a switch 16 is fixedly connected to the left side of the L-shaped plate 3. The switch 16 is electrically connected to the telescopic rod 8 and the vacuum cleaner 206 respectively. A protective cover 17 is arranged outside the switch 16. The front end of the right side of the protective cover 17 is rotatably connected to the left side of the L-shaped plate 3. Support feet 18 are fixedly connected to the four corners of the bottom of the base 1, and rubber pads 19 are fixedly connected to the bottoms of the support feet 18;

[0036] Specifically, the switch 16 can freely control the operation of the telescopic rod 8 and the vacuum cleaner 206. The protective cover 17 can prevent the switch 16 from being accidentally touched. The support feet 18 and the rubber pads 19 can make the base 1 more stable.

[0037] Refer to Figure 3 and Figure 4 , chutes 20 are respectively arranged on the upper and lower sides inside the first groove 5. Sliders 21 are fixedly connected to the upper and lower sides of the two moving blocks 7. Multiple sliders 21 slide inside the corresponding chutes 20 respectively. Soft pads 22 are fixedly connected to the outer walls of the two fixed rings 11. Rubber strips 23 are equidistantly fixedly connected to the outer walls of the soft pads 22. A second groove 13 is arranged on the front side of the fixing plate 12. The size of the second groove 13 is the same as that of the limiting plate 15;

[0038] Specifically, the chutes 20 and the sliders 21 can make the movement of the moving blocks 7 more stable. The rubber strips 23 can increase the friction force. The same size of the second groove 13 and the limiting plate 15 can make the limiting plate 15 more stable.

[0039] Working principle: When using the positioning device for fixed denture production, the denture needs to be placed on the front side of the limiting plate 15 first. At this time, rotate the threaded rod 6 to make the moving block 7 move, drive the extension plate 9 and the fixed rod 10 to move, and adjust the fixed rod 10 according to the denture. At the same time, turn on the switch 16 to make the telescopic rod 8 work and contract, so that the fixed rod 10 and the limiting plate 15 clamp the denture;

[0040] And after grinding, debris will be generated. Part of the debris will fall into the dust storage groove 204, and some debris will fall to other positions of the equipment. At this time, remove the suction head 202 from the U-shaped frame 201, and at the same time turn on the switch 16 to make the vacuum cleaner 206 work. The debris is sucked through the suction pipe 203 and the suction head 202 and enters the dust storage groove 204 through the dust inlet 205.

[0041] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
