[0002] After making the shape of the inner crown of the metal porcelain denture, it is necessary to check whether there are small tumors on the inner and outer surfaces of the crown, and remove them with a small grinding head, take out the teeth adjacent to the trial mold, smear the trial mold with printing oil, gently try the casting on the mold and then take it out, check the imprint on the casting, and use a tungsten carbide steel drill bit to gently grind and trim the imprint part. This process requires repeated trial wear and grinding until the inner crown is fully in place, the casting can be smoothly and completely in place on the mold without warping, and the inner crown has a smooth surface.
[0003] However, the above-mentioned inner crown processing method is cumbersome and is generally handled manually. Due to the small shape of the denture itself, it is difficult to operate manually, making it difficult to ensure the production quality of the denture, resulting in low production efficiency. To this end, we proposed a high-precision inner crown processing device for preparing metal porcelain dentures. Utility Model Content
[0004] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

The inner crown processing device is easy to operate, does not require manual grinding of the inner crown, reduces the difficulty of manual processing, makes the production quality of dentures more stable, and improves production efficiency.
[0006] Furthermore, the fixing mechanism includes a turntable fixedly connected to the output end of the reduction motor, the turntable is a hollow structure, the bottom surface of the turntable is rotatably connected to the top surface of the operating table, the left side of the inner wall of the turntable is rotatably connected with a bidirectional screw rod, the right end of the bidirectional screw rod extends to the right side of the turntable, the left and right sides of the bidirectional screw rod wall are threadedly connected with moving blocks, the left and right sides of the top surface of the turntable are provided with sliding openings, the top surfaces of the two moving blocks are respectively extended to the top surface of the turntable through corresponding sliding openings, the top surfaces of the two moving blocks are fixedly connected with connecting rods, and the upper ends of the two connecting rods are fixedly connected with clamping blocks.
[0007] Furthermore, the right end of the bidirectional screw rod is fixedly connected with a torsion bar.
[0008] Furthermore, the surface of the twister is provided with a plurality of anti-slip grooves.
[0009] Furthermore, a protective block is fixedly connected to the center of the top surface of the turntable, and the material of the protective block is sponge.
[0010] Furthermore, the top surface of the protection block is concave.
[0011] Furthermore, the surfaces and inner walls of the two clamping blocks are provided with friction increasing blocks, and the material of the friction increasing blocks is rubber.
[0012] The beneficial effects of the utility model are as follows:
[0013] 1. During the use of the utility model, when it is necessary to process the outer surface of the inner crown, the distance between the two clamping blocks is adjusted by twisting the bidirectional screw rod so that the two clamping blocks can extend into the inner crown, the inner crown is inserted into the two clamping blocks, and the twisting blocks are rotated in the opposite direction so that the clamping blocks clamp the inner crown. At this time, the outer surface of the inner crown is exposed without any foreign matter blocking it. After the small nodules and marks on the outer surface of the inner crown are identified by the identification sensor, the mechanical arm is started to move the grinding ball and the reduction motor is coordinated to rotate the inner crown. The grinding ball is moved to the place with the small nodules and marks, and the grinding motor is started to rotate the grinding ball to process it. When it is necessary to process the inner surface of the inner crown When performing processing, after adjusting the distance between the two clamping blocks, the inner crown is turned upside down and inserted between the two clamping blocks, so that the clamping blocks clamp the inner crown. At this time, the inner surface of the inner crown is exposed, without any foreign matter blocking it. After the recognition sensor identifies the nodules and marks on the inner surface of the inner crown, the mechanical arm is started to move the grinding ball and the reduction motor is coordinated to rotate the inner crown. The grinding ball is moved to the place with the nodules and marks, and the grinding motor is started to rotate the grinding ball to process it.

[0014] 2. The turning knob facilitates the rotation of the bidirectional screw rod, which helps to make the internal crown processing device more convenient to use. The anti-slip pattern increases the friction between the turning knob and the hand, which helps to rotate the bidirectional screw rod.
[0015] 3. When the inner crown processing device processes the inner surface of the inner crown, the bottom of the inner crown can be attached to the protective block to prevent the inner crown from sinking and directly contacting the turntable during processing, thereby causing wear. The friction increasing block helps to increase the friction between the clamping block and the inner crown to ensure the clamping fixation of the inner crown. BRIEF DESCRIPTION OF THE DRAWINGS
