Description

Technical Field

[0001] The utility model relates to the field of cutting, in particular to a tooth forming cutting knife. Background Art

[0002] Teeth are an important part of human chewing food, and they are also an indispensable part of a person's appearance. Therefore, when teeth are diseased or shifted, dentists are often needed to replace or correct them. When dentists correct teeth, a tooth-forming cutter is usually required for correction.

[0003] In order to save replacement materials, existing tooth shaping cutters often adopt a mode in which the cutting blade and the cutting knife are separated. After the cutting blade and the cutting knife are fixed by screws, they are inserted into a motor to drive rotation. The high-speed rotation of the cutting knife can remove the diseased part of the tooth and grind the distorted part.

[0004] In order to avoid splashing of tooth debris and control the temperature of the cutting blade during cutting, this type of tooth forming cutter is usually sprayed with professional coolant. In order to allow medical staff to concentrate on their work, the water spraying personnel usually work separately and synchronously with the cutting personnel. However, because the operation is performed in the oral cavity, it is difficult for the two to work synchronously during the operation. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the existing tooth forming cutting tool cannot be cooled by water spraying synchronously.

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is: a tooth forming cutting knife, comprising a cutting knife, the cutting surface of the cutting knife is provided with a plurality of cutting blades, the cutting surface of the cutting knife is provided with a fixing groove for fixing the cutting blades, the interior of the cutting knife is provided with a cooling device, and the opposite side of the cutting surface of the cutting knife is provided with a spindle center internal cooling device for driving the cutting knife.

[0007] As an improvement, the cooling device includes a cooling main hole passing through the cutting tool, cooling sub-holes distributed on the side wall of the fixing groove, and a nozzle located at the outlet side of the cooling sub-hole.

[0008] As an improvement, the nozzle is connected to the cooling sub-hole via waterproof glue.

[0009] As an improvement, the cutting blade is connected to the side wall of the fixing groove through a bolt structure, and the cutting blade is located below the cooling sub-hole.

[0010] As an improvement, a connecting prism is provided on the opposite side of the cutting surface of the cutting tool, a spiral bayonet for fixing the connecting prism is provided on the output side of the spindle center internal cooling device, and the main cooling hole passes through the connecting prism.

[0011] As an improvement, a water outlet corresponding to the cooling main hole is provided inside the spiral bayonet, and the cooling main hole is connected to the water outlet via a sealing ring.

[0012] Compared with the prior art, the utility model has the following advantages: the utility model delivers coolant to the cooling main hole through the water outlet at the output end of the spindle center internal cooling device, and the cooling main hole and the cooling sub-hole deliver cooling water to the side of the cutting blade. The cooling water is broken up into cooling water mist through the nozzle, so that it is evenly sprayed on the cutting blade, and the powder cut by the teeth is also flushed by the cooling water mist, so that it flows out, avoiding the powder from being inhaled into the respiratory tract.
