[0002] Dentures are artificial teeth that replace missing natural teeth. Dentures need to be fixed during the processing process. The dentures are fixed with a fixed bracket for operation and processing. However, the existing denture processing denture fixed brackets still have certain defects, such as:

[0003] The "denture fixing bracket for denture processing" with application number CN202321185144.X cannot be turned over after the denture is fixed during use, and can only be processed on one side of the denture. When the other side of the denture needs to be processed, the denture can only be re-clamped and fixed, which not only increases the operation process, but also reduces the efficiency of denture processing, and has limitations in use;

[0004] In view of this, an in-depth study was conducted on the above-mentioned problem, and a denture processing denture fixing bracket with a flip limiting function was proposed. Summary of the invention

[0005] The object of the present invention is to provide a denture processing and denture fixing bracket with a flipping and limiting function, so as to solve the problem of the reciprocating flipping of the existing denture processing and denture fixing bracket proposed in the above background technology.

[0028] 1. Start the first motor to rotate the bidirectional screw rod, so that the two mounting plates move toward each other, so that the mounting shaft and the clamping plate move inward, and then the denture placed on the top surface of the bearing plate is clamped and fixed. At this time, the denture can be operated and processed;

[0029] 2.

After the round rod rotates and hits the straight rod, it will push the straight rod and the driven broken gear to deflect, ensuring that the driving broken gear will mesh with the driven broken gear, thereby driving the driven broken gear and the hollow tube to rotate. When the driving broken gear rotates and separates from the driven broken gear, the limit block will rotate to match the limit groove, limit the driven broken gear and the hollow tube, and realize that the driven broken gear and the hollow tube rotate 180° during the process of the driving broken gear rotating one circle, and at the same time the bearing plate moves upward to the initial position;

[0053] Working principle: When in use, the artificial tooth to be processed is placed on the top surface of the bearing plate 7, and the first motor 11 is started to rotate the bidirectional screw rod 12, so that the two mounting plates 3 threadedly connected with the bidirectional screw rod 12 move toward each other, so that the mounting plate 3 drives the mounting shaft 4 and the clamping plate 5 to move synchronously, and then the artificial tooth is clamped and fixed by the two clamping plates 5, so that the artificial tooth can be processed;

[0054] When the denture needs to be turned over, the second motor 13 is started to rotate the rotating shaft 6, and the reciprocating screw 15 is rotated through the action of the bevel gear set 14, so that the moving plate 17 drives the sliding rod 18 and the bearing plate 7 to reciprocate, and the bearing plate 7 will move downward first;

[0055] At the same time, when the rotating shaft 6 rotates, it drives the active pulley 19 to rotate, and the driven pulley 21 drives the rotating rod 9 to rotate through the action of the belt 20. The rotating rod 9 drives the active broken gear 22 to rotate, and the round rod 24 will rotate synchronously with the active broken gear 22. The rotating round rod 24 will contact the straight rod 27. At the same time, the limiting block 23 rotating with the active broken gear 22 will be separated from the limiting groove 26, so that the round rod 24 pushes the straight rod 27 and the driven broken gear 25 to produce a certain deflection, ensuring that the rotating active broken gear 22 will mesh with the driven broken gear 25, so that the driven broken gear 25 is driven to rotate. The rotation of the driven broken gear 25 drives the hollow tube 10 to rotate synchronously, and drives the installation shaft 4, the clamping plate 5 and the fixed artificial tooth to rotate through the setting of the connecting slider 28 and the connecting slot 29. At this time, the bearing plate 7 moves downward to leave enough space for the rotation of the artificial tooth.

[0056] When the active broken gear 22 rotates to separate from the driven broken gear 25, the driven broken gear 25, the hollow tube 10, the mounting shaft 4 and the clamping plate 5 are rotated 180°, thereby realizing the flipping of the denture. When the active broken gear 22 is separated from the driven broken gear 25, the limit block 23 will rotate to coincide with the limit groove 26, so that the driven broken gear 25 is limited, thereby ensuring the limitation of the hollow tube 10, the mounting shaft 4, the clamping plate 5 and the denture. At the same time, during the flipping of the denture, the bearing plate 7 will move upward. When the active broken gear 22 rotates one circle, the bearing plate 7 completes a reciprocating movement stroke and is placed in the initial position for subsequent processing.
