Description

Technical Field

[0001] The present invention relates to the technical field of denture processing machinery, in particular to a denture grinding machine and a grinding method thereof. Background Art

[0002] Dentures, also known as false teeth, are manufactured through a multi-step process. First, an impression material is used to create a negative mold in the mouth. This mold is then cast into a plaster model, which is then further cast into a wax model. This wax model is then used as a mold for the tray, and finally, the denture is made from the tray mold. It's worth noting that the tray molds created through casting often have a lot of burrs, so they are usually polished with a grinder to improve the quality of the finished denture.

[0003] Most grinders currently on the market operate by mechanical grinding, that is, relying on the high-speed rotation of the grinding tool to grind the denture material. However, given that dentures have different material properties and rich and diverse shape structures, this puts more stringent requirements on the adaptability of the grinder and the grinding effect.

[0004] In order to meet different grinding needs, existing denture grinding machines are generally equipped with grinding tools of different types and specifications. However, in actual use, the replacement and adjustment procedures of these grinding tools are extremely cumbersome and complicated, which not only consumes a lot of time, but may also affect the grinding accuracy due to improper operation. Moreover, during the grinding process, the high-speed friction between the grinding tool and the denture material can easily generate a large amount of heat. If this heat cannot be dissipated in time, it will have a negative impact on the grinding effect, such as causing defects such as thermal deformation and burn marks on the denture surface. At the same time, it will also change the original performance of the denture material, reducing its key indicators such as strength, toughness or wear resistance, thereby affecting the service life and wearing comfort of the denture. In addition, from the overall operational level, existing denture grinding machines generally have low grinding efficiency, making it difficult to complete high-quality grinding tasks in a short period of time, and its grinding accuracy is difficult to be stably and reliably guaranteed. Problems such as uneven grinding of the denture surface, local over-grinding or insufficient grinding are prone to occur, resulting in poor fit between the denture and the oral cavity, affecting the patient's usage experience. Summary of the Invention

A cylindrical grinding tool 154 is provided inside the storage box 151. The conical grinding tool 152, the spherical grinding tool 153 and the cylindrical grinding tool 154 are all equipped with mounting rods 155. A mounting hole 156 is provided inside the mounting seat 14. The conical grinding tool 152, the spherical grinding tool 153 and the cylindrical grinding tool 154 are installed inside the placement slot 157 in order from left to right. The control assembly 19 includes a force sensor 191, which is mounted on the base disc 2. A temperature sensor 192 is installed inside the disc 6. A high-definition camera 193 is installed on the mounting seat 14. An image recognition screen 194 is installed on the right side of the base 1. After completing the firm clamping and precise positioning of the denture, the controller 20 issues precise instructions to drive the motor 13 to start quickly and run stably. The motor 13 drives the mounting seat 14 to rotate at high speed and smoothly by virtue of its powerful power output. The mounting seat 14 can conveniently install various shapes and specifications of grinding tools through its unique internal mounting assembly 15 to meet the complex and changeable grinding requirements of the denture. The operator can flexibly select conical grinding tools 152, spherical grinding tools 153 or cylindrical grinding tools 154 from the carefully configured storage box 151 according to the specific denture material, shape and required grinding accuracy.

The carefully configured cooling assembly 17 in the cooling box 16 works synchronously with other components during the grinding operation to provide reliable cooling guarantee for the entire grinding process. The circulating pump 171 is like a strong heart, continuously extracting the coolant inside the cooling box 16 and accurately delivering it to the nozzle 173 through a soft and durable hose 172. The nozzle 173 sprays the coolant on the grinding area in the form of a uniform and fine spray, like a timely rain, which can quickly take away the large amount of heat generated during the grinding process, effectively preventing the denture from deformation, damage and other quality problems due to overheating, and ensuring that the physical and chemical properties of the denture are not affected. At the same time, the coolant can also wash away impurities such as debris and dust generated by grinding during the spraying process, keeping the grinding area clean and hygienic, creating a good working environment for the grinding operation, further improving the grinding quality and production efficiency of the denture, reducing surface defects and quality defects of the denture caused by residual impurities, and extending the service life and use effect of the denture.

[0028] A method for grinding a denture grinding machine: first, place the denture on the clamping assembly 7 in the disc 6, and rotate the turntable 71 to drive the screw 72 to rotate. Since the screw 72 is threadedly connected to the disc 6, the screw 72 will push the connecting block 74 to move. The clamping block 75 on the connecting block 74 slides under the guidance of the guide groove 76 and cooperates with the stop block 73 to clamp the denture. The insertion rod 51 in the connecting disc 4 is inserted into different sockets 52 to adjust the relative position of the connecting disc 4 and the base 3, thereby changing the position of the disc 6 and the denture, and controlling The controller 20 controls the motor 13 to start, and the motor 13 drives the mounting seat 14 to rotate. Different grinding tools can be installed on the mounting seat 14 through the mounting assembly 15; the operator can select a conical grinding tool 152, a spherical grinding tool 153 or a cylindrical grinding tool 154 from the storage box 151, and screw its mounting rod 155 into the mounting hole 156 of the mounting seat 14 to meet different grinding requirements; during the grinding process, the force sensor 191 on the base plate 2 can sense the grinding force, and the temperature sensor 192 in the disc 6 can monitor the temperature of the grinding tool. The high-definition camera 193 on the mounting seat 14 captures the grinding situation and transmits it to the image recognition screen 194 on the right side of the base 1, facilitating real-time monitoring and adjustment by the operator. The sliding assembly 10 in the connecting seat 9 can adjust the height position of the grinding seat 21. Rotating the turntable 101 drives the rotating rod 102 to rotate, and the gear 103 on the rotating rod 102 engages with the rack 104 on the support rod 8, so that the connecting seat 9 drives the rotating seat 11 to slide on the support rod 8; the rotational connection between the rotating seat 11 and the rotating block 12, and the rotational connection between the rotating block 12 and the grinding seat 21, allow the grinding seat 21 to rotate flexibly in multiple directions, thereby achieving grinding of different angles and positions of the denture. The cooling assembly 17 in the cooling box 16 works synchronously during grinding. The circulating pump 171 transports the coolant in the cooling box 16 to the nozzle 173 through the hose 172. The nozzle 173 sprays the coolant on the grinding area to cool the denture, prevent damage due to overheating, and remove impurities such as debris generated by grinding, thereby ensuring a clean grinding environment and high-quality dentures.

[0029] Working principle: When using this device, first place the denture on the clamping assembly 7 in the disc 6, and drive the screw 72 to rotate by rotating the turntable 71. Since the screw 72 is threadedly connected to the disc 6, the screw 72 will push the connecting block 74 to move.

During the grinding process, the force sensor 191 on the base plate 2 can sense the grinding force, and the temperature sensor 192 in the disc 6 can monitor the temperature of the base plate 2. The temperature is measured, and the high-definition camera 193 on the mounting seat 14 captures the grinding situation and transmits it to the image recognition screen 194 on the right side of the base 1, which is convenient for the operator to monitor and adjust in real time. The sliding assembly 10 in the connecting seat 9 can adjust the height position of the grinding seat 21. Rotating the turntable 101 drives the rotating rod 102 to rotate, and the gear 103 on the rotating rod 102 engages with the rack 104 on the support rod 8, so that the connecting seat 9 drives the rotating seat 11 to slide on the support rod 8. The rotational connection between the rotating seat 11 and the rotating block 12 and the rotational connection between the rotating block 12 and the grinding seat 21 allow the grinding seat 21 to rotate flexibly in multiple directions, thereby realizing grinding of different angles and positions of the denture. The cooling assembly 17 in the cooling box 16 works synchronously during grinding. The circulating pump 171 transports the coolant in the cooling box 16 to the nozzle 173 through the hose 172.

Since the screw (72) is threadedly connected to the disc (6), the screw (72) will push the connecting block (74) to move. The clamping block (75) on the connecting block (74) slides under the guidance of the guide groove (76) and cooperates with the block (73) to clamp the denture. The insertion rod (51) in the connecting disc (4) is inserted into different jacks (52) to adjust the relative position of the connecting disc (4) and the base (3), thereby changing the position of the disc (6) and the denture. The controller (20 ) controls the motor (13) to start, and the motor (13) drives the mounting seat (14) to rotate. Different grinding tools can be installed on the mounting seat (14) through the mounting assembly (15); the operator can select a conical grinding tool (152), a spherical grinding tool (153) or a cylindrical grinding tool (154) from the storage box (151), and screw its mounting rod (155) into the mounting hole (156) of the mounting seat (14) to meet different grinding requirements; during the grinding process, the force sensor (191) on the base disc (2) can sense the grinding force, and the temperature sensor (192) in the disc (6) can sense the grinding force. The temperature is monitored, and the high-definition camera (193) on the mounting seat (14) takes a picture of the grinding situation and transmits it to the image recognition screen (194) on the right side of the base (1), so that the operator can monitor and adjust it in real time. The sliding assembly (10) in the connecting seat (9) can adjust the height position of the grinding seat (21). The rotating disk (101) drives the rotating rod (102) to rotate, and the gear (103) on the rotating rod (102) engages with the rack (104) on the support rod (8), so that the connecting seat (9) drives the rotating seat (11) to slide on the support rod (8); the rotating seat (11) and the rotating block (12) The rotational connection of the rotating block (12) and the rotational connection of the grinding seat (21) enable the grinding seat (21) to be flexibly rotated in multiple directions, thereby realizing grinding of different angles and positions of the denture. The cooling assembly (17) in the cooling box (16) works synchronously during grinding. The circulating pump (171) transports the coolant in the cooling box (16) to the nozzle (173) through the hose (172). The nozzle (173) sprays the coolant on the grinding area to play a cooling role, prevent the denture from being damaged due to overheating, and take away impurities such as debris generated by grinding, thereby ensuring a clean grinding environment and the quality of the denture.
