Description

Technical Field

[0001] The utility model relates to the technical field of porcelain fused to metal crown grinding, in particular to a trimming and grinding device for porcelain fused to metal crowns. Background Technique

[0002] Porcelain fused to metal crown is an ideal restoration. It first uses a ceramic base, and then a low-fusing porcelain powder similar to natural teeth is covered on its surface and sintered and fused in a vacuum high-temperature porcelain furnace. Therefore, it has high strength and the beauty of a porcelain full crown. Its characteristics are that it can restore the shape and function of the tooth body, has strong fracture resistance, a realistic color appearance, a smooth surface, strong wear resistance, and will not deform, and the color is stable.

[0003] In order to make the surface of the porcelain fused to metal crown smoother, remove possible rough or uneven parts, and improve the overall aesthetics, it is usually necessary to perform grinding treatment on it. In current dental clinics, doctors and technicians usually use handheld and desktop polishers to perform the grinding work for tooth whitening. However, this traditional operation method has many problems. First, because the handheld polisher is light in weight and lacks sufficient stability, it often causes instability of dental tools (such as drills and diamond discs), resulting in tool sliding or rotation, increasing the risk of tool breakage. Second, due to the structural limitations of the handheld polisher, it often cannot provide a large enough polishing force, which may not be sufficient for areas that require deep cleaning.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work belong to the scope of protection of the present utility model.

[0021] Please refer to Figures 1-4 As shown, a trimming and grinding device for porcelain teeth includes a bottom plate 1. A fixing frame 2 is fixed on the top of the bottom plate 1. A grinding member 3 for grinding porcelain teeth is arranged on the inner wall of the fixing frame 2. Here, it should be noted that the grinding member 3 is composed of a cylinder, a motor, a connecting plate and a sand disc, which is prior art and will not be elaborated here. Its function is to grind porcelain teeth with high strength. A fixing tube 4 is arranged above the bottom plate 1. A driving member 5 is arranged on the inner wall of the fixing tube 4. A push rod 6 is arranged on one side of the driving member 5. A mounting plate 7 is fixed on one side of the fixing frame 2. A fixing rod 8 installed horizontally is fixed on one side of the mounting plate 7. A spring 9 is sleeved on the outer side of the fixing rod 8. One end of the spring 9 is fixed with a clamping rod 10. By setting the fixing rod 8, it is convenient to limit the clamping rod 10. By setting the spring 9, it is convenient for the clamping rod 10 to rebound to its original position, and thus it is convenient to clamp and grind the next group of porcelain teeth. Two rollers 11 are rotatably arranged on the top of the clamping rod 10, and the rollers 11 are used in cooperation with the push rod 6. A clamping plate 12 for clamping porcelain teeth is installed on one side of the clamping rod 10.

[0022] A mounting frame 13 is arranged on one side of the clamping plate 12. A plurality of mounting bolts 14 are threadedly connected to the inner wall of the mounting frame 13. By setting the mounting frame 13 and the mounting bolts 14 in cooperation, it is convenient to install and replace the clamping plate 12.

[0023] Two limiting plates 15 are fixed on one side of the fixing frame 2, and the other end of the spring 9 is fixed to the side of the limiting plate 15. By setting the limiting plate 15, it is convenient to fix the spring 9.

[0024] A support plate 16 is fixed on the top of the bottom plate 1. A fixing ring 17 for improving the stability of the fixing tube 4 is fixed on the top of the support plate 16. By setting the support plate 16 and the fixing ring 17 in cooperation, it is convenient to install and fix the fixing tube 4.

[0025] A fixing shaft 18 for improving the stability of the two clamping rods 10 is rotatably arranged on the bottom plate 1, and the upper end of the fixing shaft 18 is rotatably connected to the inner wall of the fixing frame 2. By setting the fixing shaft 18, it is convenient to improve the stability of the two clamping rods 10.

[0026] The driving member 5 includes a crank 51 located on one side of the fixed tube 4. One end of the crank 51 is fixed with a threaded rod 52, and the outer side of the threaded rod 52 is threadedly connected to the inner wall of the fixed tube 4 and rotatably connected to one end of the push rod 6. By providing the crank 51, it is convenient to drive the threaded rod 52 to rotate. By providing the threaded rod 52, it is convenient to drive the push rod 6 to move.

[0027] Working principle: First, place the porcelain tooth into the clamping plate 12, and then rotate the driving member 5. The rotation of the driving member 5 drives the push rod 6 to move. The movement of the push rod 6 drives the roller 11 to move outwards. The outward movement of the roller 11 drives the two clamping rods 10 to move towards each other, and then drives the two clamping plates 12 to move towards each other to clamp and fix the porcelain tooth. Then, start the air cylinder and the motor in the grinding member 3. The start of the air cylinder drives the motor, the connecting plate and the grinding disc to move downwards. The rotation of the motor drives the connecting plate and the grinding disc to rotate. By providing the connecting plate, it is convenient to install the grinding disc. When the grinding disc moves to a suitable position, the porcelain tooth can be ground.
