Description

Technical Field

[0001] The utility model belongs to the technical field of artificial teeth processing, and particularly relates to a cutting device for artificial teeth processing. Background Art

[0002] Dentures, also known as false teeth, are artificial teeth used to replace teeth that are naturally lost due to disease, trauma, age and other factors. They are designed to restore the patient's chewing function, maintain facial shape and improve pronunciation. Dentures can be divided into different types such as full dentures and partial dentures (such as removable dentures and fixed dentures). The materials used to make them include metals, ceramics, resins, and high polymers. Modern denture processing usually uses precise digital design and advanced manufacturing technologies, such as CAD / CAM (computer-aided design and computer-aided manufacturing), to ensure the accuracy, comfort, and aesthetics of the dentures. Cutting devices for denture processing refer to professional equipment used for fine cutting, trimming, and grinding of denture materials during the denture manufacturing process. Such devices usually include high-precision cutting tools (such as high-speed rotating diamond grinding wheels, carbide tool heads, etc.), precise motion control systems, and stable operating platforms. They can perform precise contour cutting, internal channel excavation, surface polishing, and other process treatments on denture substrates such as ceramic blocks and resin blocks according to pre-set design data to form customized dentures that ultimately meet the patient's oral condition and aesthetic needs. In some existing cutting devices for denture processing, the cutting angle of the cutting knife is fixed and the adaptability is limited.

[0003] For example, the utility model with announcement number CN216417370U discloses a cutting device for denture processing, in which a cutting blade is fixedly connected to one side of a first rotating rod. In the present patent scheme, the cutting angle of the cutting blade is fixed. The cutting blade with a fixed angle may not be able to flexibly cope with denture materials of different shapes, sizes and materials, especially those with complex three-dimensional geometric structures or special surface requirements. For certain specific processing paths or parts, the fixed cutting blade angle may not be the optimal cutting posture, which may cause accelerated tool wear, increased cutting force, and extended processing time, thereby affecting the overall production efficiency. Utility Model Content

[0004] In view of this, the utility model aims to address the deficiencies of the prior art and provides a cutting device for denture processing. The cutting knife angle can be adjusted. The cutting angle of the tool can be accurately set and adjusted according to the specific requirements of the denture design and the material properties, ensuring that the tool is always in the most suitable cutting state to adapt to diverse processing needs.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a cutting device for denture processing, comprising a processing table, a slide rail is arranged at the upper end of the processing table, a frame is arranged for sliding inside the slide rail, a screw rod 1 is arranged for rotation inside the slide rail, the frame is threadedly connected to the screw rod 1, a slider is arranged for sliding inside the frame, a screw rod 2 is arranged for rotation inside the frame, the slider is threadedly connected to the screw rod 2, an electric push rod 1 is arranged at the left end of the slider, a rotating plate is arranged on the telescopic end of the electric push rod 1, a motor 3 is rotatably connected to the inside of the rotating plate through a rotating shaft, a cutting knife is arranged on the output shaft of the motor 3 through a coupling, an electric drive unit 1 for driving the screw rod 1 to rotate is arranged on the rear side of the slide rail, and an electric drive unit 2 for driving the screw rod 2 to rotate is arranged on the upper end of the frame.

[0007] As a further improvement of the utility model, a support plate is arranged at the upper end of the processing table, and a chip suction pipe is arranged inside the support plate.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] First, the denture to be cut is placed between two clamping plates, and then the second electric push rod is controlled to operate, so that the telescopic end drives the clamping plates on both sides to move closer together to fix dentures of different sizes.

[0010] Secondly, by controlling the operation of motor three, the output shaft drives the cutting knife to rotate, and then by controlling the operation of electric push rod one, the telescopic end operates to move the cutting knife to the position where cutting is required. Then, by controlling the operation of motor one, the output shaft rotates to drive screw one to rotate, so that the cutting knife on the frame can move to achieve front and back cutting of the denture.

[0011] Thirdly, by turning on the third operation of the electric push rod, the telescopic end drives the rack plate to move, so that the gear meshing with it rotates to drive the third motor on the rotating shaft to rotate, so as to realize the angle adjustment of the cutting knife to adapt to different cutting angles. The cutting knife angle can be adjusted. According to the specific requirements of the denture design and the material properties, the cutting angle of the tool can be accurately set and adjusted to ensure that the tool is always in the most suitable cutting state to adapt to diverse processing needs.

[0012] Fourthly, by connecting the chip suction pipe to an external dust suction mechanism, the waste chips generated during the denture processing and cutting can be sucked away and collected, making the working environment cleaner. BRIEF DESCRIPTION OF THE DRAWINGS
