Technical Field

[0001] The utility model relates to the field of denture processing devices, in particular to a brushless grinding device for denture processing. Background Art

[0002] In medicine, dentures are a general term for restorations made after partial or complete tooth loss in the upper and lower teeth. Dentures are divided into two types: removable and fixed. Fixed dentures cannot be taken on and off by the patient themselves, while removable dentures can be taken on and off conveniently by the patient. Dentures include crowns, removable dentures, etc. As an important part of the field of oral implant technology, they were generally manufactured through steps such as denture molding, molding, grinding and polishing in the early days. With the continuous improvement of technology, emerging technologies such as 3D printing have been able to be applied to denture processing. However, no matter what method is used to manufacture the denture, it is necessary to use a grinding device to grind and polish it before it is finally implanted in the patient's mouth.

[0003] A grinding device that uses a brushless motor as a power source is called a brushless grinding device. Compared with traditional brushed motors, it has the advantages of long life, high efficiency, low maintenance cost, low noise, and high speed.

[0004] Since a large amount of dust and debris are generated when the denture is polished, the existing brushless polishing device can only polish the denture, but is not convenient for collecting and processing the dust and debris, and is in urgent need of improvement. Utility Model Content

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 3As shown, a brushless grinding device for denture processing includes an operating table 1 and a grinder. The operating table 1 has a hollow structure inside, and a storage groove and a fixing groove are provided on the top surface. The size of the storage groove is adapted to the size of the grinder. A plurality of through holes connected to the inside of the operating table 1 are provided on the side of the fixing groove, and a filter plate 2 is installed inside the operating table 1 between the storage groove and the fixing groove. An opening is provided on the rear end surface of the operating table 1, and a discharge port is provided on the side. There are two openings, and a protective net 5 is installed at the opening. A fan 3 is installed at the opening inside the operating table 1, and a sealing plate 4 is installed at the discharge port.

[0022] Grinding work is performed right above the fixed groove. When the fan 3 is working, air flow is transported to the outside of the operating table 1, so that the air above the fixed groove enters the inside of the operating table 1 through the through hole. The dust and some debris generated during grinding follow the air flow into the inside of the operating table 1 and are retained in the inside of the operating table 1 under the action of the filter plate 2. The sealing plate 4 is opened to discharge the filtered debris; some large particles of debris generated during grinding will fall onto the fixed groove. When grinding is completed, the debris can be pushed into the inside of the operating table 1 through the through hole using a tool.

[0023] like Figure 1 , Figure 4 and Figure 5 As shown, the grinder includes a shell 6, a brushless motor 7 is installed inside the shell 6, the output shaft of the brushless motor 7 is detachably connected to a grinding head 9 through a positioning column 8, the positioning column 8 is fixedly installed on the output shaft of the brushless motor 7, a connecting rod 10 is fixedly connected to one end of the grinding head 9, the connecting rod 10 is movably connected to the positioning column 8, the connecting rod 10 is a square rod, the positioning column 8 is a cylinder, and a socket matched with the connecting rod 10 is opened in the middle, the end of the connecting rod 10 is magnetized, and an iron block 11 is fixedly connected to the inner bottom surface of the socket, a battery 12 and a circuit board 13 are installed on one side of the brushless motor 7 inside the shell 6, and a power button 14 is provided on the side of the shell 6, and a charging interface is provided at the end.

[0024] The brushless motor 7 drives the connecting rod 10 and the grinding head 9 to rotate through the positioning column 8, so that the denture can be polished. By magnetizing the end of the connecting rod 10 and cooperating with the iron block 11, the grinding head 9 can be prevented from falling off, and the grinding head 9 can be pulled outward and the connecting rod 10 is separated from the positioning column 8, so that the grinding head 9 can be removed and replaced. The connecting rod 10 is a square rod to prevent the connecting rod 10 and the positioning column 8 from rotating relative to each other.

[0025] During specific use, the fan 3 is turned on, and the denture is polished just above the fixed groove. Some debris generated during polishing will fall directly into the fixed groove, and some debris and dust follow the downward airflow above the fixed groove into the interior of the operating table, and are retained inside the operating table 1 under the action of the filter plate 2. After polishing is completed, a tool is used to push the debris into the interior of the operating table 1 through the through hole, and the sealing plate 4 is opened to discharge the dust and debris inside the operating table 1.
