Description

Technical Field

[0001] This utility model belongs to the field of root canal file tipping technology, and more specifically, it relates to an automatic root canal file tipping device. Background Technology

[0002] The tip shape of a root canal file directly affects its cutting ability. By sharpening the tip, the angle and sharpness of the cutting edge can be adjusted, enabling the root canal file to more efficiently remove infected dentin, pulp tissue, or blockages in the root canal after entering the root canal, reducing the number of repeated operations and shortening the treatment time. Existing automatic root canal file sharpening devices can only perform the entire process of positioning, clamping, grinding, and testing of one root canal file at a time, which greatly limits the output per unit time, prolongs the overall production cycle, and results in a slow processing speed. Therefore, an automatic root canal file sharpening device is proposed. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an automatic root canal file sharpening device that can process two root canal files simultaneously. This solves the problem mentioned in the background technology that the entire process of positioning, clamping, grinding, and inspecting only one root canal file at a time can be performed, which significantly limits the output per unit time and prolongs the overall production cycle.

[0021] Please see Figures 1 to 4This utility model provides a technical solution: an automatic tipping device for root canal files, including a base plate 1, a first support 2 and a second support 3 fixed on the top surface of the base plate 1, a transmission cylinder 4 rotatably connected to the inner side of the first support 2, a transmission rod 5 rotatably connected to the inner side of the transmission cylinder 4, a grinding wheel 6 coaxially fixed at one end of the transmission cylinder 4 and one end of the transmission rod 5, a first motor 7 fixed to one side of the first support 2, a first bevel gear 8 coaxially fixed to the output end of the first motor 7, a second bevel gear 9 and a third bevel gear 10 respectively meshing on both sides of the first bevel gear 8, a sliding groove 11 opened on one side of the second support 3, two sliding blocks 12 slidably connected inside the sliding groove 11, and a connecting groove opened inside each of the two sliding blocks 12, the two connecting grooves being... A pneumatic chuck 13 is rotatably connected to the second bracket 3. Two movable plates 14 are slidably connected to the other side of the second bracket 3. A second motor 15 is fixed to one side of the movable plate 14. A third motor 16 is also fixed to the other side of the second bracket 3. A bidirectional lead screw 17 is coaxially fixed to the output end of the third motor 16. The bidirectional lead screw 17 is threadedly connected to the two movable plates 14. The upper and lower positions of the two connecting grooves are staggered. The centers of the two connecting grooves correspond to the positions of the two grinding wheels 6. The center of the transmission cylinder 4 coincides with the center of the transmission rod 5. The inner side of the second bevel gear 9 is coaxially fixedly connected to one end of the transmission cylinder 4. The output end of the second motor 15 is coaxially fixedly connected to one end of the pneumatic chuck 13. The inner side of the third bevel gear 10 is coaxially fixedly connected to one end of the transmission rod 5. In use, the root canal file is inserted into the pneumatic chuck 13 and secured. Then, the third motor 16 drives the bidirectional lead screw 17 to rotate. The bidirectional lead screw 17 moves the two movable plates 14 towards the center, which in turn moves the two sliding blocks 12 and the two pneumatic chucks 13 towards the center. When the root canal file on the pneumatic chuck 13 contacts the grinding wheel 6, the second motor 15 is activated to rotate the pneumatic chuck 13 and the root canal file. During this process, because the two connecting grooves are staggered vertically, their centers correspond to the positions of the two grinding wheels 6, ensuring that the upper and lower root canal files correspond to the positions of the two grinding wheels 6. Finally, the first motor 15 is activated... Machine 7, the first motor 7 drives the first bevel gear 8 to rotate, the first bevel gear 8 drives the transmission cylinder 4 and the transmission rod 5 to rotate in opposite directions through the second bevel gear 9 and the third bevel gear 10 respectively. The transmission cylinder 4 and the transmission rod 5 drive the two grinding wheels 6 to rotate in opposite directions, so that the grinding wheels 6 rotate in the direction of the root canal file. Through the above process, two root canal files can be processed at the same time, which improves the output per unit time. At the same time, the structure is compact and occupies a small area. It solves the problem that the entire process of positioning, clamping, grinding and testing of only one root canal file at a time can be performed at a time, which greatly limits the output per unit time, prolongs the overall production cycle and slows down the processing speed.

[0022] The specific usage and function of this embodiment: When using this utility model, the root canal file is inserted into the pneumatic chuck 13 and fixed. Then, the third motor 16 drives the bidirectional lead screw 17 to rotate. The bidirectional lead screw 17 drives the two movable plates 14 to move towards the center. The movable plates 14 drive the two sliding blocks 12 and the two pneumatic chucks 13 to move towards the center. When the root canal file on the pneumatic chuck 13 contacts the grinding wheel 6, the second motor 15 is started to drive the pneumatic chuck 13 and the root canal file to rotate. During this process, since the upper and lower positions of the two connecting grooves are staggered, the centers of the two connecting grooves correspond to the positions of the two grinding wheels 6, so that the upper and lower root canal files correspond to the positions of the two grinding wheels 6. Finally, the first motor 7 is started, and the first motor 7 drives the first bevel gear 8 to rotate. The first bevel gear 8 drives the transmission cylinder 4 and the transmission rod 5 to rotate in opposite directions through the second bevel gear 9 and the third bevel gear 10, respectively. The transmission cylinder 4 and the transmission rod 5 drive the two grinding wheels 6 to rotate in opposite directions, so that the grinding wheels 6 rotate in the direction of the root canal file.
