[0002] A denture is a false tooth inserted to restore functions such as chewing, aesthetics, and pronunciation after tooth loss or extraction. It is generally divided into removable dentures and fixed dentures, and various materials are used. Currently, the most common type is a denture made by casting the dental phosphate casting investment material to form the tooth shape and filling the inside with an alloy.

[0003] The patent with publication number CN219819235U discloses a denture grinding device. By arranging a telescopic cylinder, a telescopic rod, and a rubber fixing block on the end face of the device main body, the device can achieve a stable fixing effect. By arranging a connecting plate, fixing bolts, and a motor, the rotating shaft can obtain power. By arranging the rotating shaft, the rotational power of the motor can be transmitted to the telescopic cylinder and the telescopic rod. Through the above arrangements and processes, the telescopic cylinder, the telescopic rod, and the rubber fixing block can rotate under the drive of the motor when fixing the denture, enabling the fixed denture to achieve a multi-angle rotation effect, facilitating the operator to grind and improving the grinding efficiency. However, the following problems still exist in the actual use of this patent: Although this denture grinding device can achieve a stable fixing effect by arranging a telescopic cylinder, a telescopic rod, and a rubber fixing block on the end face of the device main body, since the denture is not in a flat state, it is impossible to accurately control the distance between the large grinding wheel and the denture during grinding, and it is impossible to maintain an appropriate force and correct angle, resulting in excessive grinding, causing the denture to deform or the surface to be damaged. At the same time, it is impossible to protect metal components (such as clasps and supports), and it is impossible to ensure the occlusal surface shape of artificial teeth during adjustment and grinding. Due to excessive grinding of cusps or fossae, the chewing efficiency is affected.

[0004] Therefore, a denture grinding and trimming device is proposed to solve the problems mentioned above. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: the denture grinding and trimming device, through the elastic force of the protective spring, can enable the protective bracket and the inclined protective bracket to support the denture grinding surface, thereby avoiding the phenomenon that the grinding force and angle are affected by slight shaking of the grinding head during denture grinding, causing excessive grinding and leading to denture deformation or surface damage. The user lies on the bottom of the operation box through a reclining chair and uses a reinforced rubber clamp to fix the head. The operator can manually operate the rubber sleeve to perform slight grinding and trimming on the denture, thereby improving the comfort of denture use. The specific contents are as follows: 1. By setting up the grinding and finishing mechanism, not only can the switching and adjusting motor drive the switching and adjusting disc and the fixed sleeve to rotate, which can not only achieve the angle adjustment of the grinding head, but also can switch different grinding heads according to the grinding needs of the denture, and at the same time can switch the cleaning brush to clean the dust generated by the grinding of the denture surface. By aligning the mounting blocks on both sides of the grinding connecting shaft with the vertical slots and inserting them into the inner part of the mounting sleeve, when the mounting block moves to the horizontal rotation groove, by horizontally rotating the grinding connecting shaft and driving the mounting block to horizontally rotate inside the horizontal rotation groove, the mounting block can cross the spring limit block, thus locking the mounting block, which is convenient for the quick installation and disassembly of the grinding connecting shaft and the grinding head. When grinding the denture, since the surface of the denture to be ground is not a flat surface, and at the same time the cusp and fossa of the denture need to be ground, it is necessary to precisely control the grinding head. Through the elastic force of the protective spring, the protective bracket and the inclined protective bracket can support the grinding surface of the denture, avoiding the phenomenon that during the grinding of the denture, due to the slight shaking of the grinding head, it affects the grinding force and angle, resulting in over-grinding and causing the deformation or surface damage of the denture. When it is necessary to polish the denture, by increasing the downward pressure, under the action of the inclined surface of the inclined protective bracket, the inclined protective bracket rises, and at the same time the polishing surface of the grinding head is exposed, so as to carry out the polishing after the denture is ground. Through the protective effect of the protective bracket and the inclined protective bracket, it can reduce the amplitude of the grinding head caused by improper operation during the grinding of the denture, thereby improving the stability of the denture grinding, enabling stable grinding and polishing of the denture, reducing the defective rate of the denture grinding. When grinding the denture, by using the suction force generated by the dust suction fan, the powder generated by the grinding is sucked into the dust suction box through the annular dust suction nozzle. Under the combined action of the first dust-proof net and the second dust-proof net, the dust generated by the polishing can be filtered. By opening the mounting cover, the first dust-proof net and the second dust-proof net can be cleaned. By using the telescopic effect of the telescopic protective cover, the dust can be better absorbed, improving the efficiency of dust absorption. By starting the rotating motor to drive the rotating worm to rotate, using the characteristic of the meshing connection between the rotating worm and the rotating worm gear, the second adjusting disc rotates, which is convenient for the angle adjustment of the grinding head. At the same time, start the second adjusting motor to drive the first adjusting screw rod to rotate, so that the adjusting thread sleeve drives the first electric telescopic rod to move, which can adjust the position of the grinding head. At the same time, the height of the grinding head can be adjusted through the first electric telescopic rod, which is convenient for the all-round grinding of the denture; 2. By setting up the fixed support mechanism, not only can the operator observe the grinding situation of the denture through the viewing window, but also the staff can insert their arms into the inner part of the operating rubber sleeve to perform manual operations. This enables manual grinding of complex parts of the denture, improving the grinding effect of the denture. Utilizing the sliding connection between the moving chute and the moving slider, the fixed plate can be moved out from the bottom of the operating box. When moving the fixed plate, the fixed plate descends under the action of the inclined section of the moving chute. At the same time, by rotating the lever, the installation rotating disc is driven to rotate. Utilizing the sliding connection between the clamping block and the spiral limiting bracket, the clamping block drives the clamping sliding sleeve and the clamping sliding frame to move relatively, facilitating the clamping and fixing of the denture. By rotating the first adjustment knob to drive the second adjustment screw rod to rotate, the relative position between the denture fixing blocks can be adjusted. This can not only clamp and fix a single denture but also clamp and fix a full set of dentures, facilitating the grinding of the denture. By rotating the second adjustment knob to drive the adjustment rotating rod and the bevel gear transmission assembly to rotate, the bevel gear transmission assembly drives the lifting screw rod to rotate. At the same time, the lifting thread sleeve drives the lifting rotating rod and the adjustment support plate to rotate. By rotating the support and the second electric telescopic rod, the movement of the reinforcement rubber clamp can be realized, which can reinforce both sides of the denture, improving the stability of denture grinding. At the same time, when the denture user needs to slightly grind the denture, the fixed plate can be moved away from the bottom of the operating box. The user lies on the bottom of the operating box through the reclining chair and uses the reinforcement rubber clamp to fix the head. The operator can perform manual operations through the operating rubber sleeve to slightly grind and trim the denture, improving the comfort of denture use. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0019] Please refer to Figures 1 - 3 , the present invention provides a technical solution: a denture grinding and trimming device, including a grinding and trimming mechanism 1, and a mounting top plate 120 installed on the top of the grinding and trimming mechanism 1. A fixed support mechanism 2 is arranged at the bottom of the grinding and trimming mechanism 1, and reinforcing brackets 223 are symmetrically arranged inside the fixed support mechanism 2.

Vertical slots 109 are symmetrically opened inside the mounting sleeve 108. Horizontal rotation slots 110 are symmetrically opened in the middle of the mounting sleeve 108. Spring limit blocks 111 are fixedly installed in the middle of the two horizontal rotation slots 110. Mounting blocks 112 are slidably connected inside the two horizontal rotation slots 110. A grinding connection shaft 113 is fixedly installed between the two mounting blocks 112. A second fixed disk 114 is fixedly installed on the outer side of the grinding connection shaft 113. A grinding head 115 is fixedly installed at the bottom of the grinding connection shaft 113. By driving the switching and adjusting disk 103 and the fixed sleeve 104 to rotate with the switching and adjusting motor 102, not only can the angle adjustment of the grinding head 115 be realized, but also different grinding heads 115 can be switched according to the grinding needs of the denture. At the same time, a cleaning brush can be switched to clean the dust generated by the grinding of the denture surface. By aligning the mounting blocks 112 on both sides of the grinding connection shaft 113 with the vertical slots 109 and inserting them into the mounting sleeve 108, when the mounting block 112 moves to the horizontal rotation slot 110, by horizontally rotating the grinding connection shaft 113 and driving the mounting block 112 to horizontally rotate inside the horizontal rotation slot 110, the mounting block 112 can cross the spring limit block 111, thereby locking the mounting block 112, which is convenient for the quick installation and disassembly of the grinding connection shaft 113 and the grinding head 115.

[0020] Please refer to Figures 3 - 6, a first rotating disk 116 is rotatably connected to the bottom of the second fixed disk 114. Four sides around the bottom of the first rotating disk 116 are fixedly installed with protective springs 117. The bottom of the protective springs 117 is fixedly installed with a protective bracket 118. The bottom of the protective bracket 118 is fixedly installed with an inclined protective frame 119. The top of the installation top plate 120 is fixedly installed with a dust suction box 121. The top of the dust suction box 121 is threadedly connected with an installation cover 122.

The telescopic protective cover 130 is fixedly installed on the top of the switching and adjusting bracket 101. The bottom center position of the installation top plate 120 is fixedly installed with a third fixed disk 131. When grinding dentures, since the surface to be ground of the denture is not a flat surface and the cusps and fissures of the denture need to be ground, precise control of the grinding head 115 is required. Through the elastic force of the protective spring 117, the protective bracket 118 and the inclined protective frame 119 can support the grinding surface of the denture, avoiding the phenomenon that when grinding the denture, due to slight shaking of the grinding head 115, it affects the grinding force and angle, resulting in over-grinding and causing deformation or surface damage of the denture. When polishing the denture, by increasing the downward pressure, under the action of the inclined surface of the inclined protective frame 119, the inclined protective frame 119 rises, and at the same time, the polishing surface of the grinding head 115 is exposed, so as to perform the polishing after denture grinding. Through the protective effect of the protective bracket 118 and the inclined protective frame 119, it can reduce the amplitude of the grinding head 115 caused by improper operation during denture grinding, thereby improving the stability of denture grinding, enabling stable grinding and polishing of dentures, reducing the defective rate of denture grinding. When grinding dentures, using the suction force generated by the dust suction fan 123, the powder generated by grinding is sucked into the dust suction box 121 through the annular dust suction nozzle 129. Under the combined action of the first dust-proof net 124 and the second dust-proof net 125, the dust generated by polishing can be filtered. By opening the installation cover 122, the first dust-proof net 124 and the second dust-proof net 125 can be cleaned. Utilizing the telescopic function of the telescopic protective cover 130, it can better absorb the dust and improve the dust absorption efficiency. In the prior art, although the angle and height of the grinding equipment are adjusted by a motor, there will be a certain amount of shaking during the movement of the grinding equipment. Since the arc of the denture grinding surface is relatively large, the weak amplitude change will still have a certain impact on the surface grinding of the denture.Thus, it affects the effect of denture grinding.

By starting the rotating motor 133 to drive the rotation of the rotating worm 134, using the meshing connection between the rotating worm 134 and the rotating worm gear 135, the second adjusting disc 136 is rotated to facilitate the angle adjustment of the grinding head 115. At the same time, start the second adjusting motor 137 to drive the rotation of the first adjusting screw rod 138, so that the adjusting thread sleeve 139 drives the first electric telescopic rod 140 to move, which can adjust the position of the grinding head 115.

A second electric telescopic rod 232 is rotatably connected to the outer side of the rotating support 231. A reinforcing rubber clamp 233 is fixedly installed at the end of the second electric telescopic rod 232. By rotating the first adjusting knob 221 to drive the second adjusting screw rod 220 to rotate, the relative positions between the denture fixing blocks 222 can be adjusted. It can not only clamp and fix a single denture, but also clamp and fix a complete denture, facilitating the grinding of the denture. By rotating the second adjusting knob 224 to drive the adjusting rotating rod 225 and the bevel gear transmission components 226 to rotate, the bevel gear transmission components 226 drive the lifting screw rods 227 to rotate. At the same time, the lifting screw sleeves 228 drive the lifting rotating rods 229 and the adjusting support plate 230 to rotate. The movement of the reinforcing rubber clamp 233 can be realized through the rotating support 231 and the second electric telescopic rod 223, which can reinforce both sides of the denture and improve the stability of denture grinding. At the same time, when the denture user needs to slightly grind the denture, the fixing plate 208 can be removed from the bottom of the operation box 202. The user lies on the bottom of the operation box 202 through the reclining chair and uses the reinforcing rubber clamp 233 to fix the head. The operator can manually operate through the operation rubber sleeve 204 to slightly grind and trim the denture, improving the comfort of denture use.

[0024] Working principle: Before using this denture grinding and trimming device, it is necessary to first check the overall situation of the device to determine that it can work normally. According to Figure 1 - Figure 11As shown in the figure, first, the visual window 203 facilitates the operator to observe the grinding condition of the denture. At the same time, the staff can extend their arm into the operation rubber sleeve 204 to perform manual operations, enabling manual grinding of the complex parts of the denture and improving the grinding effect of the denture. Utilizing the sliding connection between the moving chute 205 and the moving slider 206, the fixed plate 208 can be moved out from the bottom of the operation box 202. Meanwhile, when moving the fixed plate 208, the fixed plate 208 descends under the action of the inclined section of the moving chute 205. At the same time, by rotating the lever 215, the mounting rotating disc 214 is driven to rotate. Utilizing the sliding connection between the clamping block 218 and the spiral limiting bracket 213, the clamping block 218 drives the clamping sliding sleeve 217 and the clamping sliding frame 219 to move relatively, facilitating the clamping and fixing of the denture. By rotating the first adjustment knob 221 to drive the second adjustment threaded rod 220 to rotate, the relative position between the denture fixing blocks 222 can be adjusted, enabling not only the clamping and fixing of a single denture but also the clamping and fixing of a complete denture, facilitating the grinding of the denture. By rotating the second adjustment knob 224 to drive the adjustment rotating rod 225 and the bevel gear transmission assembly 226 to rotate, the bevel gear transmission assembly 226 drives the lifting threaded rod 227 to rotate. At the same time, the lifting threaded sleeve 228 drives the lifting rotating rod 229 and the adjustment support plate 230 to rotate. By rotating the support 231 and the second electric telescopic rod 232, the movement of the reinforcing rubber clip 233 can be realized, enabling the reinforcement of both sides of the denture and improving the stability of denture grinding. At the same time, when the denture user needs to slightly grind the denture, the fixed plate 208 can be moved away from the bottom of the operation box 202. The user lies on the bottom of the operation box 202 through the reclining chair and uses the reinforcing rubber clip 233 to fix the head. The operator can perform manual operations through the operation rubber sleeve 204 to slightly grind and trim the denture, improving the comfort of denture use.

[0025] Secondly, the switching and adjusting motor 102 is used to drive the switching and adjusting disc 103 and the fixed sleeve 104 to rotate, which can not only realize the angle adjustment of the grinding head 115, but also switch different grinding heads 115 according to the grinding needs of the denture. At the same time, the cleaning brush can be switched to clean the dust generated by the grinding of the denture surface. By aligning the mounting blocks 112 on both sides of the grinding connecting shaft 113 with the vertical slots 109 and inserting them into the inside of the mounting sleeve 108, when the mounting block 112 moves to the horizontal rotation groove 110, the grinding connecting shaft 113 is horizontally rotated to drive the mounting block 112 to horizontally rotate inside the horizontal rotation groove 110, so that the mounting block 112 crosses the spring limit block 111, thereby locking the mounting block 112, which is convenient for the quick installation and disassembly of the grinding connecting shaft 113 and the grinding head 115. When grinding the denture, since the surface of the denture to be ground is not a flat surface and the cusp and fossa of the denture need to be ground, accurate control of the grinding head 115 is required. Through the elastic force of the protective spring 117, the protective bracket 118 and the inclined protective frame 119 can support the grinding surface of the denture, avoiding the phenomenon that the slight shaking of the grinding head 115 during the denture grinding affects the grinding force and angle, resulting in over-grinding and causing the deformation or surface damage of the denture. When the denture needs to be polished, by increasing the downward pressure, under the action of the inclined surface of the inclined protective frame 119, the inclined protective frame 119 rises, and at the same time, the polishing surface of the grinding head 115 is exposed, so as to perform the polishing after the denture grinding.

[0026] Through the protective effects of the protective bracket 118 and the inclined protective frame 119, the amplitude of the grinding head 115 caused by improper operation during denture grinding can be reduced, thereby improving the stability of denture grinding, enabling stable grinding and polishing of the denture, and reducing the defective rate of denture grinding. When grinding the denture, the suction force generated by the dust suction fan 123 is used to suck the powder generated by grinding into the dust suction box 121 through the annular dust suction nozzle 129. Under the combined action of the first dust-proof net 124 and the second dust-proof net 125, the dust generated by polishing can be filtered. By opening the mounting cover 122, the first dust-proof net 124 and the second dust-proof net 125 can be cleaned. Utilizing the telescopic function of the telescopic protective cover 130 can better absorb the dust and improve the dust absorption efficiency. By starting the rotating motor 133 to drive the rotating worm 134 to rotate, and using the meshing connection characteristic between the rotating worm 134 and the rotating worm gear 135, the second adjusting disc 136 is rotated, which is convenient for adjusting the angle of the grinding head 115. At the same time, starting the second adjusting motor 137 to drive the first adjusting screw rod 138 to rotate, so that the adjusting thread sleeve 139 drives the first electric telescopic rod 140 to move, the position of the grinding head 115 can be adjusted, and at the same time, the height of the grinding head 115 can be adjusted through the first electric telescopic rod 140, which is convenient for the all-round grinding of the denture.
