[0002] Dentures are a type of dental prosthesis used to replace missing teeth. Dentures are made of materials such as resin, zirconium oxide, and metal.

[0003] In the process of using zirconia cakes to process dentures, the zirconia cake is first placed in a CNC milling machine and clamped and positioned using a fixture.

[0018] Compared with the prior art, the present invention provides a fully automatic denture processing device, which has the following beneficial effects:

[0019] 1. The fully automatic denture processing device, according to actual usage, when replacing zirconia cakes of different diameters and thicknesses for processing, only needs to place the zirconia cake between the two arc-shaped clamping plates, and use the convex column to perform preliminary placement and positioning, push the zirconia cake to move, drive the first movable column to move together, the connecting block moves with the first movable column, and the rack column moves with the connecting block, thereby driving the second gear to rotate, and then driving the first gear to rotate, and adjusting the arc-shaped clamping plate to clamp the zirconia cake, which can adapt to clamping zirconia cakes of different diameters, multiple second movable columns are in contact with the zirconia cake, and relative sliding occurs between the second movable column and the second circular hole, and the third spring is stretched, and the fixed block cooperates with the adjusting column to drive the arc-shaped clamping block to clamp the zirconia cake, and the elastic force and elasticity of the third spring can be used to clamp and position zirconia cakes of different thicknesses, without adjusting or replacing the fixture, which can shorten the equipment downtime and thus improve the denture processing efficiency.

[0020] 2. In the fully automatic denture processing device, each time the tool is replaced, relative sliding occurs between the first slider and the first electric slide rail, the tool is aligned with the placement hole on the surface of the lifting block, driving the lifting block to move downward, the first spring is compressed, relative movement occurs between the fixed rod and the fixed sleeve, relative movement occurs between the protrusion and the spiral groove, and then the rotating sleeve is driven to rotate, and the cleaning brush cleans the tool surface to avoid affecting the next milling process. That is, each time the tool is replaced, the tool can be cleaned in time to remove the attached zirconium oxide powder and other residues to ensure that the tool remains sharp. A clean tool can reduce the error generated during the cutting process, thereby improving the processing accuracy and ensuring that the size and shape of the denture meet the design requirements.

[0021] 3. In the fully automatic denture processing device, during the process of clamping the zirconia cake, the first movable column and the rectangular block move together, the trapezoidal block can first contact the inclined block, and relative movement occurs between the trapezoidal block and the inclined block, and the trapezoidal block moves in the direction of compressing the fourth spring, and then the trapezoidal block is placed between the inclined block and the adjusting block. When the zirconia cake is clamped, the trapezoidal block can be in close contact with the surface of the inclined block. After the denture processing is completed, the zirconia cake is pushed to move in the direction close to the U-shaped plate, the trapezoidal block contacts the first inclined groove on the surface of the adjusting block and generates relative movement, and then closely contacts the surface of the second inclined groove; under the action of the second spring and the fourth spring elastic force, the trapezoidal block and the adjusting block move together in the direction close to the inclined block. After the adjusting block contacts the inclined block, the trapezoidal block can again generate relative sliding between the adjusting block, and then contact the inclined block and generate relative sliding, and then separate from the inclined block, which is convenient for the unloading of the processed zirconia cake, speeds up the transfer and processing speed of the zirconia cake, and further improves the processing efficiency.

The trapezoidal block 625 and the inclined block 626 move relative to each other. Then, the trapezoidal block 625 separates from the inclined block 626. Under the elastic force of the fourth spring 623, the trapezoidal block 625 can contact the surface of the U-shaped plate 3. At this time, the trapezoidal block 625 is between the inclined block 626 and the adjusting block 627.

[0049] See also Figure 6 , the initial state of the fourth spring 623 is a compressed state;

[0050] It should be noted that the reaction force generated by the compression of the fourth spring 623 acts on the upper end of the cylinder 624, so that the trapezoidal block 625 can be in close contact with the surface of the U-shaped plate 3 during the adjustment and movement, and can be in close contact with the surfaces of the inclined block 626, the first inclined groove 6211 and the second inclined groove 6212.
