Description

Technical Field

[0002] Removable dentures, also known as removable partial dentures, are restorations provided to patients who have lost part or all of their upper or lower teeth. They need to have sufficient strength and stability to ensure comfort and functionality in daily use. During the production and processing of removable dentures, ensuring their strength and durability is crucial. Through testing with detection devices, it is possible to screen out those dentures that perform well in tensile strength, thereby extending their service life in the patient's mouth and reducing the need for frequent replacement and the associated costs.

[0003] The removable denture to be tested is firmly mounted on the test platform through a specific fixing fixture, and a gradually increasing tensile force is applied by the loading system. While the tensile force is being applied, the measurement system starts working. The measurement system usually includes sensors, such as force sensors and displacement sensors. The force sensor is used to accurately measure the applied tensile force value, and the displacement sensor is used to monitor the displacement or deformation of the denture under the action of the tensile force. These measurement data will be collected in real time and transmitted to the data processing system. The data processing system analyzes and processes the collected data and draws a curve showing the relationship between the tensile force and the displacement or deformation. By analyzing these curves, the tensile performance of the removable denture can be evaluated.

[0026] The denture model 12 can be fixed on the top of the placement table 3 through the fixing component to prevent the denture model 12 from being displaced during the process of testing the tensile performance of the denture model 12, which will affect the detection effect. The driving component can drive the gear 2 18 and the rotating shaft 17 to rotate, thereby driving the clamping component and the tension component to rotate, so as to adjust the direction of the clamping component and the tension component so that any tooth in the denture model 12 can be subjected to tensile testing. The tooth to be tested can be clamped by the clamping component, and the tension component can apply tension to the tooth clamped by the clamping component.

[0027] Reference Figure 1 、 Figure 2 and Figure 3 The fixed component includes a movable plate 6, the top of the movable plate 6 is fixedly connected to the output ends of the two electric telescopic rods 7, a connecting groove 8 is opened in the middle of the movable plate 6, a vacuum pump 9 is fixedly connected to the middle of the top of the movable plate 6, and the output end of the vacuum pump 9 is fixedly connected to a vacuum tube 10, which is located at the top end of the connecting groove 8.

[0028] Since the top of the movable plate 6 is fixedly connected to the output end of the electric telescopic rod 7, starting the electric telescopic rod 7 to extend the electric telescopic rod 7 will drive the movable plate 6 to move downward. When the bottom end of the suction cup 11 is in close contact with the top of the denture model 12, the vacuum pump 9 is started to enable the vacuum tube 10 to extract the air inside the communicating groove 8 and the air between the suction cup 11 and the denture model 12, thereby fixing the denture model 12 on the top of the placement table 3, preventing the denture model 12 from being displaced during the process of testing the tensile performance of the denture model 12, thereby affecting the detection effect.

[0030] By starting the driver 23, the bidirectional screw 24 is driven to rotate, so that the slider 25 moves simultaneously inside the bidirectional screw 24 on the same side toward the center direction of the fixed plate 21, thereby clamping the teeth. Since the sleeve 19 is fixedly connected to the rotating shaft 17, when the rotating shaft 17 rotates, the sleeve 19, the telescopic block 20 and the fixed plate 21 will be driven to rotate at the same time. When the fixed plate 21 is subjected to tension, the telescopic block 20 will be driven to stretch.

[0031] Reference Figure 2 、 Figure 4 and Figure 5The tension component includes a fixed plate 28, a limiting groove 29 is provided in the middle of the top of the fixed plate 28, the bottom end of the limiting plate 27 is slidably connected to the limiting groove 29, the rear end of the fixed plate 28 is fixedly connected with a fixed block 37, the middle of the fixed block 37 is fixedly connected to the outer bottom end of the rotating shaft 17, the front end and left and right sides of the fixed plate 28 are provided with a through groove 1 30 on both sides of the limiting groove 29, the interior of the fixed plate 28 is provided with a movable groove 31 on the side away from the through groove 1 30, the top and left sides of the fixed plate 28 are fixedly connected with a driver 2 32, and the output of the two drivers 2 32 The output ends are fixedly connected with connecting shaft 2 33, and the bottom ends of connecting shaft 2 33 are fixedly connected with gear 34 inside the movable groove 31 on the same side, and the opposite end of gear 34 is meshed with rack 35 inside the through groove 1 30 on the same side, and the opposite ends of rack 35 are fixedly connected to the left and right sides of limit plate 2 27 respectively, and rack 35 is slidably connected to through groove 1 30 on the same side. Column blocks 36 are fixedly connected to the front and rear sides of the bottom end of fixed plate 2 28, and an annular groove 1 38 and an annular groove 2 39 are provided at the top of the base 1, and the two column blocks 36 are slidably connected to the annular groove 1 38 and the annular groove 2 39 respectively.

[0032] By starting driver 2 32 at the same time, the connecting shaft 2 33 and gear 3 34 on the same side can be driven to rotate, and the two gears 34 rotate in opposite directions, thereby driving the two racks 35 to move synchronously inside the through groove 1 30 on the same side, thereby driving the limit plate 2 27 to slide inside the limit groove 29. Since the limit plate 27 is fixed to the fixed plate 1 21, the limit plate 27 moves outward, which will drive the fixed plate 1 21 to move outward, causing the telescopic block 20 to stretch, and drive the two splints 26 to move outward at the same time, pulling the teeth clamped by the splints 26 in the vertical direction of the teeth, and the fixed block 37 is fixed to the rotating shaft 17. When the rotating shaft 17 rotates, it will drive the fixed block 37 and the fixed plate 2 28 to rotate synchronously. When the fixed plate 28 rotates, it will drive the two column blocks 36 to slide inside the annular groove 1 38 and the annular groove 2 39 respectively.

[0033] Reference Figure 1 and Figure 2 The driving assembly includes a support block 13 and a motor 14. The rear ends of the support block 13 and the motor 14 are fixedly connected to the front end of the support plate 2. The output end of the motor 14 is fixedly connected to a connecting shaft 15. The outer side of the connecting shaft 15 is fixedly connected to a gear 16. The bottom end of the connecting shaft 15 is rotatably connected to the top end of the support block 13, and the outer end of the gear 16 is meshed with the outer end of the gear 2 18.

[0034] The starting motor 14 drives the connecting shaft 15 and the gear 1 16 to rotate. Since the gear 1 16 is meshed with the gear 2 18 , the rotation of the gear 1 16 drives the gear 2 18 to rotate in the opposite direction.

[0035] Working principle: by placing the support block 13 on the top front side of the placement table 3, and the teeth on the denture model 12 are located on the front side of the placement table 3, and the bottom of the teeth are located below the bottom end of the placement table 3, then start the electric telescopic rod 7 to drive the movable plate 6 to move downward, when the bottom of the suction cup 11 is in close contact with the top of the denture model 12, start the vacuum pump 9 to make the vacuum tube 10 extract the air between the connecting groove 8, the suction cup 11 and the denture model 12, thereby fixing the denture model 12, and then start the motor 14 to rotate the gear 16 to drive the gear 2 18 and the rotating shaft 17 to reverse, and move the splint 26 to the required position. At the tooth to be tested, start driver 1 23 to drive the bidirectional screw 24 to rotate, so that the opposite side of the splint 26 clamps the tooth, and then start driver 2 32 at the same time to make the two connecting shafts 2 33 rotate in opposite directions, driving the rack 35 to move forward. The rack 35 is connected to the limit plate 2 27, and the top of the limit plate 27 is fixedly connected to the bottom of the fixed plate 1 21. Therefore, when the rack 35 moves, it will synchronously drive the limit plate 2 27 and the fixed plate 1 21 to move, thereby applying tension to the tooth. The tension value is tested by various sensors and transmitted to the data processing system to evaluate the tensile performance of the denture model 12.
