[0002] Dentures are what people often call "false teeth"; just like calling "false legs" and "false limbs" "artificial limbs", "dentures" means teeth that fulfill their "duties" for humans; in medicine, it is a general term for restorations made after partial or complete loss of upper and lower teeth; dentures are divided into removable and fixed; fixed dentures (commonly known as "fixed dentures") cannot be removed and put on by the patient themselves, while removable dentures (commonly known as "removable dentures") can be easily removed and put on by the patient.
[0003] Full dentures are a type of dentures, which need to be customized manually during production. Since full dentures have a certain curvature, both the outside and the inside of the dentures need to be polished during production to ensure the accuracy of the dentures. Existing full dentures are mostly polished by hand, which is not only dangerous but also inconvenient to adjust the polishing position during the polishing process. Therefore, improvements are needed. Utility Model Content

[0024] The first limiting assembly 2 includes a first hydraulic cylinder 22 fixed to one end of the positioning platform 10. The top side of the positioning platform 10 is provided with an opening, and a first limiting rod 21 is inserted into the opening. One end of the first limiting rod 21 is connected to the first hydraulic cylinder 22. The first hydraulic cylinder 22 of the device can push the first limiting rod 21 to slide forward and backward automatically.
[0025] The second limiting assembly 5 includes a second hydraulic cylinder 53 fixed inside the positioning platform 10, a through hole is opened on the top side of the positioning platform 10, a second limiting rod 51 is inserted inside the through hole, and the outer walls of the second limiting rod 51 and the first limiting rod 21 are provided with protective rubber 52, and the protective rubber 52 is fixedly connected to the second limiting rod 51 and the first limiting rod 21 by glue; this structure prevents the second limiting rod 51 and the first limiting rod 21 from causing damage to the full denture 4 to be polished when they contact with the full denture 4 to be polished by providing the protective rubber 52; one end of the second limiting rod 51 passes through the through hole and is connected to the second hydraulic cylinder 53, and the second limiting rod 51 and the first limiting rod 21 are respectively attached to the two ends of the full denture 4 to be polished; this device can realize the automatic realization of the second limiting rod 51 through the second hydraulic cylinder 53.
[0026] Working principle: When using the customized denture preparation grinding fixture, first start the second hydraulic cylinder 53 to push the second limiting rod 51, so that the second limiting rod 51 extends out from the inside of the positioning platform 10, and then place the outer wall of the full denture 4 to be polished against the second limiting rod 51.

When polishing to the position clamped by the first limit rod 21 and the second limit rod 51, the first limit rod 21 and the second limit rod 51 at this position can be reset and retracted. Because there are multiple groups of the first limit rod 21 and the second limit rod 51, resetting one group will not have a serious impact on the stability of the full denture 4 to be polished, thereby ensuring the processing efficiency.
