Description

Technical Field

[0001] This utility model belongs to the technical field of dental prosthesis processing equipment, specifically relating to an internal grinding machine for producing dental prostheses. Background Technology

[0002] Dentures are false teeth that are fitted to restore chewing, aesthetics, and speech functions after teeth have been removed or extracted. After the dentures are cast, burrs often remain, so they need to be removed and finished with a micro-grinding machine to make the surface of the dentures smooth and flat, making it easier for patients to wear them.

[0003] A search revealed a Chinese utility model patent application with patent publication number CN222430318U, which discloses an internal grinding machine for producing dentures. The machine includes a processing mechanism, a bottom mechanism, and a top mechanism. The bottom mechanism is located at the bottom of the processing mechanism, and the top mechanism is located on the front of the bottom mechanism. The processing mechanism includes a fixed base, and a double-headed motor is snapped into the top of the fixed base. A fixing ring is threaded to the output end of the double-headed motor, and a processing cutter is threaded to the inner wall of the fixing ring. The double-headed motor, snapped into the fixed base, works in conjunction with a fixing plate on the front of the fixed base to limit the rotation of the top of the double-headed motor. A spring and a product limiting ring inside the fixing frame can limit and fix the product to be processed. After rotation, the limiting shell can be fixed to the surface of the double-headed motor.

[0004] Regarding the aforementioned technologies, the springs and product limiting rings inside the fixing frame of the internal grinding head during the grinding process are not convenient for adjusting the limiting position according to the shape of the denture, which can easily damage the denture and has poor applicability. Therefore, there is an urgent need to design an internal grinding machine for denture production to solve these problems. Utility Model Content

[0033] Working principle: In use, firstly, start the drive motor 204 to rotate clockwise, driving the lead screw 203 to rotate, which in turn drives the first moving table 205 to move relative to it, and simultaneously drives the push plate 312 to move. Place the denture to be internally ground into the elastic telescopic fixing groove 306. Then, start the drive motor 204 to rotate counterclockwise, driving the lead screw 203 to rotate, which in turn drives the first moving table 205 to move towards each other, and drives the push plate 312 to move. Stop when the push plate 312 contacts the support 307. Start the first electric telescopic rod 310 to move the telescopic table 309, the turntable 311 and the push plate 312, and push the cylinder 303 fixedly installed below the first moving support 304 and the second moving support 305 to slide in the waist-shaped groove 302, which will drive the elastic telescopic rod. The denture to be internally ground is moved within the fixed slot 306. Once it reaches the appropriate position, it stops and is fixed in place by the positioning nut 3031. Simultaneously, the infrared positioning device 313 positions the clamped denture. The double doors are closed, and the second electric telescopic rod 403 is activated to drive the stepper motor 404 and the grinding execution component to move longitudinally. At the same time, the stepper motor 404 is activated to drive the grinding execution component to rotate and grind the fixed denture. The dust collector 410 is activated to remove the dust generated by the denture during grinding. The dust enters the dust collection box 408 and the cleaning water 409 for cleaning. After a period of cleaning, the cleaning water 409 is drained through the inlet and outlet pipes 411. The dust collection box 408 is slid out from the cleaning box 407 for cleaning, thus completing the internal grinding of the denture.
