Description

Technical Field

[0001] The utility model relates to the technical field of hardness detection, in particular to a hardness detection device for denture processing. Background Art

[0002] Dentures are artificial devices used to replace missing teeth. They can be divided into removable dentures such as full dentures, partial dentures and fixed dentures such as bridges and crowns. Their function is to restore chewing function. Dentures can replace missing natural teeth and help patients chew food, thereby ensuring nutritional intake and improving appearance. Missing teeth can affect facial beauty. Dentures can restore the appearance of teeth, make patients more confident, and maintain normal oral functions: they help maintain the normal structure and function of the oral cavity, such as pronunciation and swallowing. In the field of dentures, hardness testing is an important step to ensure the quality and durability of denture materials. Hardness testing devices can help evaluate the mechanical properties of denture materials such as resins, metals or ceramics. During the denture manufacturing process, hardness testing helps to ensure the strength and wear resistance of the materials, ensuring that the dentures are durable and not easily worn when used in the mouth. The hardness standards of different materials may be different, so it is crucial to choose appropriate testing methods and equipment;

[0003] Traditional denture hardness testing devices usually consist of an indenter or indentation tool and a sample support platform. The indenter directly contacts the test sample to form an indentation for testing the denture, and the sample support platform is used to place the denture for testing.

[0004] However, the traditional denture hardness testing device has a simple structure, consisting only of an indenter and a support table. When testing dentures, it is unable to effectively clamp and fix dentures of different sizes. As a result, during the testing process, when the denture is squeezed by the indenter, it is easy to be displaced. Therefore, a hardness testing device for denture processing is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1-Figure 3 The present invention provides an embodiment of a hardness testing device for denture processing, comprising a support base 1, a support frame 2 fixedly connected to the top of the support base 1 for supporting the testing device, a motor 3 fixedly connected to the bottom of the support frame 2, a disc 7 fixedly connected to the output end of the motor 3, the disc 7 is driven to rotate by the rotation of the motor 3, the disc 7 is rotatably connected to the top of the support frame 2, a sliding groove 18 is opened inside the disc 7, the sliding groove 18 is used to limit the rotation of the disc 7, a slide rail 4 is fixedly connected to the top of the support frame 2, a sliding block 5 is slidably connected to the top of the slide rail 4, the sliding block 5 slides on the slide rail 4, a soft clamping block 6 is fixedly connected to one side of the sliding block 5, a fixed column 19 is fixedly connected to the bottom of the sliding block 5, the fixed column 19 is slidably connected to the inside of the sliding groove 18, the fixed column 19 is driven to slide along the inside of the sliding groove 18 by the rotation of the disc 7, a detection component is provided on the top of the support base 1, the detection component is used to detect the hardness of the denture, and the detection head 9 is driven by the output end of the cylinder 10 to press the denture on the worktable downward, and the hardness quality of the denture is detected by a certain pressure.

[0025] Specifically, in the process of hardness testing of dentures, first, the output end of the motor 3 drives the upper disc 7 by rotation, and the sliding groove 18 inside the disc 7 provides a trajectory for the movement of the fixed column 19. The fixed column 19 fits tightly in the sliding groove 18, and moves along the movement of the sliding groove 18. The movement of the fixed column 19 directly drives the soft clamp 6 above. The soft clamp 6 is designed to clamp the denture to ensure the stability of the sample during the testing process. As the soft clamp 6 moves, the sliding block 5 also moves on the slide rail 4, so that the entire clamping structure can accurately adjust the position to accommodate dentures of different sizes. Through this series of movements, the four soft clamps 6 can work synchronously to apply uniform extrusion force to the denture, thereby effectively clamping the sample. This design not only improves the flexibility and convenience of operation, but also ensures that the denture can be kept in the best testing position during hardness testing, thereby improving the accuracy and repeatability of the measurement. The denture is tested for its hardness and quality through a certain pressure.

[0026] Reference Figure 4The detection component includes a cylinder 10 and a detection head 9 for detecting the hardness of the denture. The cylinder 10 is fixedly connected to the top of the support base 1, and the detection head 9 is fixedly connected to the output end of the cylinder 10. The top of the support base 1 is slidably connected with a protective cover 1 8 and a protective cover 2 23. A protective effect is achieved by closing the protective cover 1 8 and the protective cover 23. The outer wall of the protective cover 1 8 is fixedly connected with a pad 22, and one side of the pad 22 is fixedly connected with a sliding frame 13. A spring 14 is provided inside the sliding frame 13. The sliding frame 13 is slidably connected with a sliding column 11. The outer wall of the sliding column 11 is slidably connected with a card rod 12. One end of the spring 14 is fixedly connected On the outer wall of the clamping rod 12, the other end of the spring 14 is fixedly connected to the bottom of the sliding frame 13, and the outer wall of the protective cover 23 is fixedly connected with a pad 21, and the self-locking structure installed on the outer wall of the protective cover 8 and the protective cover 23 is used to achieve the locking effect. The protective cover 23 and the protective cover 18 are both provided with a circular groove 17 to form a space for the detection head 9 to move. One side of the pad 21 is rotatably connected to the limit rod 16, and a spring 2 15 is provided at the bottom of the limit rod 16. The side wall of the pad 21 is fixedly connected to the support block 20, and the bottom end of the spring 2 15 is fixedly connected to the top of the support block 20, and the spring elasticity is used to achieve the effect of quick release and clamping.

[0027] Specifically, when conducting hardness testing, protective cover 1 8 and protective cover 2 23 first move synchronously toward the middle of the workbench to ensure a safe closure when in contact. During this process, the clamping rod 12 on the side of protective cover 1 8 touches the limit rod 16 of protective cover 2 23, causing the limit rod 16 to rotate due to the force. The rotation of the limit rod 16 squeezes the spring 2 15 at the bottom, causing it to shrink. When the two protective covers are completely closed, the unloading force of the spring 2 15 rebounds, pushing the limit rod 16 to rotate and lock it to the outer wall of the clamping rod 12, ensuring that the clamping rod 12 is safely buckled on the limit rod 16. After the test is completed, by pressing the limit rod 16 at the top of the spring 2 15, the clamping rod 12 connected after release is automatically pulled back into the sliding frame 13 under the action of the rebound force of the spring 1 14, so that the two protective covers are opened.

[0028] Working principle: When processing the denture and testing its hardness, first, the upper disc 7 is driven to rotate by rotating the output end of the motor 3. Since a sliding groove 18 is provided inside the disc 7, the sliding groove 18 drives the fixed column 19 fitted therewith to move along the inside of the sliding groove 18. The movement of the fixed column 19 drives the upper soft clamp 6 to move. Then the soft clamp 6 drives the sliding block 5 to move on the slide rail 4, so that the four soft clamps 6 move synchronously to achieve the extrusion and clamping of the denture. When the hardness of the processed denture is tested, first, the protective cover 1 8 and the protective cover 2 23 are moved synchronously to the middle of the workbench until the protective cover 1 8 and the protective cover 2 23 are closed. In this process, the clamping rod 12 on one side of the protective cover 1 8 will contact the limit rod 16 of the protective cover 2 23, so that the limit rod 16 is forced to rotate, and the limit rod 16 will rotate on the bottom when rotating. When the cam 12 is fully closed, the spring 15 unloads the force and rebounds, thereby pushing the limit rod 16 to rotate and engage with the outer wall of the card rod 12 to lock it, so that the card rod 12 is locked on the limit rod 16. By releasing the pressed limit rod 16 and utilizing the force of the released spring 15, the limit rod 16 is engaged with the card rod 12 to achieve self-locking of the protective cover 8 and the protective cover 23, thereby improving the safety of the hardness test. After the hardness test is completed, by pressing the limit rod 16 connected to the top of the spring 2 15, the card rod 12 engaged with it is pulled back to the inside of the sliding frame 13 by the rebound force of the spring 14, so that the card rod 12 is separated from the limit rod 16 and unlocked, thereby opening the protective cover 8 and the protective cover 23.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
