[0016] S2: When the bottom end of the top fixing mechanism contacts the top of the denture, the downward pressing mechanism will continue to drive the top fixing mechanism to move downward, so as to facilitate fixing the top of the denture through the top fixing mechanism. Since the top heights of the dentures are different, when one of the pressing blocks contacts the high part of the denture, as the top fixing mechanism moves downward, one of the pressing blocks will move upward under the action of the denture, and when the pressing block moves upward, it will drive one end of the swing plate to deflect upward, and the other end of the swing plate will drive the other pressing block to move downward, so that the other pressing block acts on the lower part of the denture, so that the top of the denture can be squeezed and fixed through the cooperation between the two pressing blocks;

At this time, the second gear will move the second rack to one side through meshing when rotating, and the second rack will push the splint to move to one side of the denture when moving. At this time, the protective pad will be fixed to the side of the denture under the action of the splint, so as to facilitate the fixing and limiting treatment of the side of the denture by the splint and the protective pad;

[0018] S4: After processing is completed, the denture can be removed from the fixed frame.

[0019] The beneficial effects of the present invention are:

[0020] 1. The present invention provides a downward pressing mechanism and a top fixing mechanism. When the denture is processed and fixed, the denture is placed on the support seat. After the placement is completed, the downward pressing mechanism is started, and the downward pressing mechanism drives the top fixing mechanism to move downward. When the bottom end of the top fixing mechanism contacts the top of the denture, the downward pressing mechanism continues to drive the top fixing mechanism to move downward, so that the top of the denture can be fixed by the top fixing mechanism. Due to the difference in the top height of the denture, when one of the pressing blocks contacts the high part of the denture, the top fixing mechanism When the structure moves downward, one of the pressing blocks will move upward under the action of the denture, and the pressing block will drive one end of the swing plate to deflect upward when moving upward, while the other end of the swing plate will drive the other pressing block to move downward, so that the other pressing block acts on the lower part of the denture, so that the top of the denture can be squeezed and fixed through the cooperation between the two pressing blocks, so as to prevent the top height of the denture from being different due to the irregular shape of the denture, thereby preventing the fixing effect of the denture from being poor, causing the denture to shake under the action of external force during processing, thereby causing deviation in the processing of the denture;

[0021] 2. The present invention provides a top fixing mechanism and a side limiting mechanism. When the top of the denture is fixed by the top fixing mechanism, the support seat will move downward under the action of pressure. At this time, the first gear will drive the rotating rod to rotate under the meshing action of the first rack, and the second gear will rotate synchronously with the rotating rod. At this time, the second gear will mesh with the second rack when rotating, and the second rack will push the splint to move to one side of the denture when moving. At this time, the protective pad will be fixed to the side of the denture under the action of the splint, so that it is convenient to fix and limit the side of the denture by the splint and the protective pad, so as to improve the processing effect of the denture and prevent the side of the denture from being offset due to external force during processing, thereby resulting in poor fixing effect of the denture, and then affecting the processing of the denture. The cooperation between the top fixing mechanism and the side limiting mechanism can effectively improve the stability of the denture fixation, thereby facilitating improving the processing effect of the denture.
