Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis processing technology, specifically to a dental prosthesis fixing mechanism for dental prosthesis processing. Background Technology

[0002] Dental prosthesis fabrication is the process of creating artificial teeth to replace missing natural teeth based on the patient's oral condition using professional techniques and processes. Its purpose is to restore the patient's chewing function, speech ability, and facial aesthetics. Dental prosthesis fabrication is divided into custom-made complete denture fabrication, custom-made fixed denture fabrication, and custom-made removable partial denture fabrication.

[0003] The existing utility model application CN215535205U discloses a denture fixing frame for denture processing. Using the above technical solution, a support plate is connected to a mounting base via a fixable ball joint. The support plate is equipped with a stop block and an arc-shaped block for clamping the denture. The denture can be fixed to the support plate, and the support plate can rotate around the mounting base to easily change the denture processing angle and facilitate adjustment. However, the above technical solution only allows changing the denture processing angle through the support plate. When the position of the denture needs to be adjusted, it needs to be removed and then fixed again, which is cumbersome and complex, easily leading to a reduction in denture processing efficiency.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention provides a denture fixing mechanism for denture processing, which has the following beneficial effects:

[0015] 1. The denture fixing mechanism for denture processing uses two electric telescopic rods installed on the inner wall of the fixing frame to drive the sliding plate and the fixing platform above to move linearly, thereby realizing the front and back position adjustment of the denture during processing. This eliminates the need to remove the denture and re-fix it, simplifying the operation process and solving the problem of low processing efficiency caused by cumbersome position adjustment in the existing technology.

[0016] 2. The denture fixing mechanism for denture processing uses a stepper motor installed in the fixing table. Through the meshing transmission of the first bevel gear and two second bevel gears, it can drive two sets of lead screws to rotate synchronously. This causes the movable block on the lead screw to move the movable plate. Together with the fixing plate and the limiting plate, it can accurately clamp and fix dentures of different sizes, avoiding the impact of denture wobbling on accuracy during processing. At the same time, the adjustment process is smooth and controllable, improving the versatility and stability of the fixing mechanism. Attached Figure Description

[0024] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a denture fixing mechanism for denture processing.

[0025] Please see Figure 1-6 This utility model discloses a denture fixing mechanism for denture processing, comprising a fixing frame 1. Two electric telescopic rods 10 are fixedly connected to the inner wall of the fixing frame 1. The telescopic ends of the two electric telescopic rods 10 are jointly fixedly connected to a sliding plate 9. A first bearing 8 is fixedly connected to the inner wall of the sliding plate 9. Four support feet 6 are fixedly connected to the bottom surface of the fixing frame 1. Two fixing rings 22 are fixedly connected to the outer surface of each set of support feet 6. The top of each set of fixing rings 22 is fixedly connected to the bottom surface of the fixing frame 1. The support feet 6 can provide stable support for the entire device, and the fixing rings 22 can reinforce the support feet 6 and the fixing frame 1, thereby enhancing the stability of the device.

[0026] A rotating rod 12 is fixedly connected to the inner ring of the first bearing 8. A fixed platform 2 is fixedly connected to the top of the rotating rod 12. A stepper motor 15 is fixedly connected to the inner wall of the fixed platform 2. A first bevel gear 20 is fixedly connected to the outer surface of the output end of the stepper motor 15. A protective seat 11 is fixedly connected to the outer surface of each electric telescopic rod 10. The left side of each protective seat 11 is fixedly connected to the inner wall of the fixed frame 1. The protective seat 11 can protect the electric telescopic rod 10 and prevent it from being damaged by the outside during use.

[0027] Two second bevel gears 21 mesh with the outer surface of the first bevel gear 20. Four support plates 16 are fixedly connected to the inner wall of the fixed platform 2. Two second bearings 18 are fixedly connected to the inner wall of each set of support plates 16. One end of one set of second bearings 18 that is close to each other is fixedly connected to the ends of the two second bevel gears 21 that are far from each other. A reinforcing plate 13 is fixedly connected to the outer surface of the rotating rod 12. The upper surface of the reinforcing plate 13 is fixedly connected to the bottom surface of the fixed platform 2. The reinforcing plate 13 can fix the rotating rod 12 and the fixed platform 2 to prevent them from shaking during use.

[0028] Each set of second bearings 18 has a lead screw 19 fixedly connected to its inner ring. The bottom surface of the sliding plate 9 is fixedly connected to a drive motor 7. The output end of the drive motor 7 is fixedly connected to the bottom end of the rotating rod 12. The inner wall of the reinforcing plate 13 is threaded with four limiting bolts 14. The outer surface of each set of limiting bolts 14 is threadedly connected to the inner wall of the fixed platform 2. The limiting bolts 14 can restrict the position of the reinforcing plate 13 and prevent it from shifting or becoming unstable during use.

[0029] The upper surface of the fixed platform 2 is fixedly connected to a limit plate 4 and two fixed plates 3. The outer surface of each lead screw 19 is threaded with a movable block 17. The upper surface of each movable block 17 is fixedly connected to a movable plate 5. The outer surface of the drive motor 7 is fixedly connected to a protective box 23. The upper surface of the protective box 23 is fixedly connected to the bottom surface of the sliding plate 9. The protective box 23 can protect the drive motor 7 and prevent it from being interfered with by external dust and impurities during use.

[0030] The working principle of this utility model is as follows: First, the denture to be processed is placed on the fixed table 2, with one side of it adhering to the limiting plate 4 and the other side close to the fixed plate 3. The stepper motor 15 is started, and its output end drives the first bevel gear 20 to rotate. Through the meshing transmission with the two second bevel gears 21, the two lead screws 19 are driven to rotate synchronously. The second bearing 18 reduces the friction when the lead screw 19 rotates. The rotation of the lead screw 19 drives the movable block 17 to move along the axial direction of the lead screw 19, thereby pushing the movable plate 5 closer to the fixed plate 3 until the movable plate 5 and the fixed plate 3 cooperate to clamp the denture and complete the fixation. When it is necessary to adjust the front and back processing position of the denture, the two electric telescopic rods 10 are controlled to extend and retract synchronously. Their telescopic ends drive the sliding plate 9 to move in a straight line, thereby driving the rotating rod 12 above the sliding plate 9, the fixed table 2 and the fixed denture to move back and forth until the target position is reached. There is no need to remove the denture and fix it again.

[0031] When it is necessary to adjust the denture processing angle, the drive motor 7 is started, and its output end drives the rotating rod 12 to rotate around the first bearing 8, thereby driving the fixed table 2 and the denture as a whole to rotate. The reinforcing plate 13 ensures that the fixed table 2 and the rotating rod 12 are stably connected during the rotation until the required angle is adjusted to meet the needs of different processing surfaces.

[0032] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model.
