Technical Field

[0002] In the field of dental restoration, the quality and performance of dental abutment screws are crucial to the overall restoration effect. Abutment screws need to withstand a certain amount of torque during use, and the accuracy of their torque value directly affects the stability of the abutment and the long-term success rate of dental restorations. Therefore, accurately measuring the torque of dental abutment screws is one of the key links to ensure the quality of dental restorations. With the continuous development of dental technology, higher requirements are placed on the accuracy, efficiency, and degree of automation of abutment screw torque testing. Traditional testing methods can no longer meet the large-scale, rapid, and accurate testing needs of modern dental restorations. An automatic torque testing device specifically for dental abutment screws is needed to improve testing efficiency and quality and ensure the smooth progress of dental restoration work.

[0003] Existing dental abutment screw torque testing usually relies on manual operation. The operator uses tools such as manual torque wrenches to test the screws one by one to ensure the installation quality and safety of the dental abutment screws. However, this manual operation is not only inefficient, but also due to the influence of human factors, such as differences in operator force control and different operating proficiency, the test results will be less accurate and stable. There will be different fluctuations in each test result, and it is impossible to ensure that accurate torque measurement can be performed on each screw. In addition, when manually testing the torque of dental abutment screws, it is difficult to ensure that the position and angle of each test are consistent for screws of different lengths, which will lead to large deviations in the torque test results. For this reason, an automatic torque meter for dental abutment screws is proposed to solve the above problems. Utility Model Content

[0029] 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.

[0030] Reference Figure 1 and Figure 2 , the utility model provides an embodiment: an automatic torque meter for dental abutment screws, comprising a base 1, a support frame 2 fixedly connected to the top of the base 1, the support frame 2 is used to support the entire device, ensure the stability of the equipment during operation and avoid shaking, a guide column 3 fixedly connected to the top of the base 1, to ensure the smooth sliding of the test component, the base 1 is electrically connected to a control switch 13, the control switch 13 is used to start and stop the torque test process, the support frame 2 is internally rotatably connected to a threaded column 4, the top of the threaded column 4 is fixedly connected to a handwheel 5, which can provide sufficient operating torque, making it convenient for the operator to adjust the position of the threaded column 4 as needed, ensuring that it can adapt to torque tests on screws of different sizes, a test component is provided on the outer wall of the guide column 3, the test component is used to test the torque of the screw, a fixing component is provided on the top of the base 1, and the fixing component is used to fix the screw;

[0031] The test assembly includes a support seat 6 and a test rod 7. The support seat 6 is slidably connected to the outer wall of the guide column 3 to ensure that the support seat 6 can move stably on the guide column 3. The test rod 7 is rotatably connected to the inside of the support seat 6. A keyway is used between the test rod 7 and the support seat 6 so that the test rod 7 can move up and down with the support seat 6 while also rotating inside it. The support seat 6 is threadedly connected to the outer wall of the threaded column 4 so that the longitudinal position of the support seat 6 can be controlled by rotating the position of the threaded column 4, thereby ensuring that the test rod 7 always remains stable during the test process. Contact force, a test head 8 is provided at the bottom end of the test rod 7 to ensure that it can accurately contact the screw and transmit torque data. A fixing seat 9 is fixedly connected to one side of the support frame 2, and a motor 10 is fixedly connected to the top of the fixing seat 9. The output end of the motor 10 is fixedly connected to a rotating column 11, and a connecting block 12 is fixedly connected to the outer wall of the rotating column 11. The test rod 7 is slidably connected to the outer wall of the rotating column 11 and the connecting block 12. The connecting block 12 is connected to the test rod 7 to ensure that when the rotating column 11 rotates, the test rod 7 also rotates, thereby testing the torque of the screw during rotation.

[0032] Specifically, when using the torque meter to test the dental abutment screw, first, the screw to be tested needs to be placed between the fixing block 15 and the clamping block 16 for firm clamping. Next, the operator turns the handwheel 5 to drive the threaded column 4 to rotate. The threaded column 4 converts the rotational motion into linear displacement through the threaded fit between the support seat 6. The movement of the support seat 6 is closely related to the rotation of the threaded column 4. When the support seat 6 is subjected to force and moves, it drives the test rod 7 connected to the support seat 6 to move linearly along the guide rail. The test rod 7 ensures the transmission and stability of the motion by closely fitting with the keyway inside the support seat 6. The bottom end of the test rod 7 is in contact with the support seat 6. The test head 8 is connected. At this time, when the test rod 7 is subjected to the transmission of force, the test head 8 at its bottom end will contact the screw to be tested. At this time, the motor 10 drives the rotating column 11 and the connecting block 12 through the transmission of its output end. The rotating column 11 and the connecting block 12 are connected to the rotating column 11, forming a force amplification and transmission structure. When the rotating column 11 is subjected to force, the connecting block 12 will rotate accordingly, thereby driving the test rod 7 connected to the outer wall to rotate. The rotation of the test rod 7 directly affects the torque applied to the screw by the test head 8, and then the torque data of the screw is detected through a series of sensor systems, thereby achieving the effect of automatically testing screws of different lengths.

[0033] Reference Figure 1 、 Figure 3 and Figure 4 The fixing component includes a support platform 14 and a fixing block 15. The bottom of the support platform 14 is fixedly connected to the top of the base 1, and the bottom of the fixing block 15 is fixedly connected to the inside of the support platform 14 to ensure the overall stability of the equipment. A clamping block 16 is slidably connected to the inside of the support platform 14, and the clamping block 16 is engaged with the fixing block 15. A support shaft 17 is fixedly connected to the top of the support platform 14, and a protrusion 18 is rotatably connected to the outer wall of the support shaft 17. One side of the protrusion 18 is protruding and eccentrically connected to the support shaft 17. A handle 19 is fixedly connected to one side of the protrusion 18, which is convenient for the user to quickly rotate the protrusion 18 when needed, thereby adjusting the working position of the equipment. A support column 20 is slidably connected to the inside of the fixing block 15 and the clamping block 16.

[0034] Specifically, during the process of screw fixing, the screw to be fixed is first placed between the fixing block 15 and the clamping block 16. At this time, by turning the handle 19, the eccentrically connected protrusion 18 on the outer wall of the support shaft 17 is driven to rotate. The eccentric design between the support shaft 17 and the protrusion 18 enables the protrusion 18 to apply a certain driving force to the clamping block 16 on one side when rotating. Due to the special shape of the protrusion 18, when it rotates, it will produce a certain longitudinal movement along the outer wall of the support shaft 17, thereby pushing the clamping block 16 to slide along the internal slide rail of the support platform 14. As the clamping block 16 slides forward, the clamping block 16 gradually engages with the two sides of the fixing block 15. This process effectively fixes the screw and prevents it from loosening or sliding. It ensures that the screw will not be displaced when subjected to external force, thereby achieving an efficient and reliable fixing effect.

[0035] Reference Figure 3 and Figure 4 The outer wall of the support column 20 is provided with a spring 21, and the two ends of the spring 21 are respectively fixedly connected to the fixed block 15 and the clamping block 16. The design of the spring 21 enables the clamping block 16 to quickly return to its original position after the test is completed. A sliding column 22 is fixedly connected to one side of the fixed block 15, and a through hole 23 is opened inside the clamping block 16. The sliding column 22 is slidably connected inside the through hole 23.

[0036] Specifically, during the sliding process of the clamping block 16, one side thereof will also come into contact with the spring 21 and exert an extruding force on the spring 21. Due to the compressive nature of the spring 21, it will gradually shrink as the clamping block 16 moves, thereby increasing the tightness of the fixation. When the screw is fixed, the user only needs to turn the handle 19 to turn the protrusion 18 back to its original position. Due to the eccentric connection between the support shaft 17 and the protrusion 18, the pushing force on the clamping block 16 will be released when it is turned back to its original position, causing the clamping block 16 to release the extruding force, so that the elastic force of the spring 21 begins to take effect, and the rebound effect of the spring 21 will push the clamping block 16 to reset, releasing the clamping force of the clamping block 16 on the fixing block 15, so that the screw can be easily removed, which not only improves work efficiency, but also makes it more convenient to fix screws of different sizes. The user does not need to frequently adjust the fixing device and can quickly adapt to screws of different specifications.

[0037] Working principle: When using the torque meter to test the dental base screw, first place the screw between the fixing block 15 and the clamping block 16 to fix it, and then turn the handwheel 5 so that it is subjected to force to drive the threaded column 4 to rotate inside the support seat 6. Through the threaded relationship between the threaded column 4 and the support seat 6, the support seat 6 is forced to move, and at the same time, the support seat 6 will be forced to drive the test rod 7 connected to the keyway inside to move. The test rod 7 is forced to drive the test head 8 at the bottom to press against the screw. At this time, the output end of the motor 10 drives the rotating column 11 and the connecting block 12 to rotate. The rotating column 11 and the connecting block 12 are forced to drive the test rod 7 connected to the outer wall to rotate, so that the test rod 7 drives the test head 8 to perform torque testing on the screw, thereby achieving the effect of automatically testing screws of different lengths. When the screw is fixed, after the screw is placed between the fixing block 15 and the clamping block 16, the handle 19 is turned so that the force drives the protrusion 18 to rotate on the outer wall of the support shaft 17. Since the support shaft 17 and the protrusion 18 are eccentrically connected, and the shape of the protrusion 18 makes the protrusion 18 push the clamping block 16 on one side to slide inside the support platform 14 when it rotates. The clamping block 16 will gradually fit into the outer wall of the fixing block 15 during the sliding process, thereby fixing the screw therebetween. At the same time, the clamping block 16 will squeeze the spring 21 during the movement, causing it to contract. When the test is completed, it is only necessary to turn the protrusion 18 back to its original position. At this time, the spring 21 unloads the force and rebounds, thereby pushing the clamping block 16 to reset, so that the screw can be quickly taken out, thereby achieving the effect of quickly and effectively fixing screws of different sizes.
