Description

Technical Field

[0001] This invention relates to the field of denture polishing technology, specifically to a denture polishing and finishing device. Background Technology

[0002] Dentures are false teeth that are fitted to restore chewing, aesthetics, and speech functions after teeth have been lost or extracted. They are generally divided into removable dentures and fixed dentures. There are various materials used, but the most common type currently is a denture made by casting a tooth shape with dental phosphate casting embedding material and filling it with an alloy.

[0003] Publication No. CN219819235U discloses a denture grinding device. By setting a telescopic cylinder, a telescopic rod, and a rubber fixing block on the end face of the device body, the device can achieve a stable fixing effect. By setting a connecting plate, fixing bolts, and a motor, the rotating shaft can obtain power. The rotating shaft allows the motor's rotational power to be transmitted to the telescopic cylinder and telescopic rod. Through the above settings and process, the telescopic cylinder, telescopic rod, and rubber fixing block can rotate under the drive of the motor when fixing the denture, allowing the fixed denture to rotate at multiple angles, facilitating grinding and improving grinding efficiency. However, this patent still has the following problems in actual use:

[0004] Although this denture grinding device can achieve a stable fixation effect by setting a telescopic cylinder, telescopic rod, and rubber fixing block on the end face of the main body of the device, it is impossible to accurately control the distance between the large grinding wheel and the denture during grinding because the denture is not in a straight position. It is also impossible to maintain appropriate force and correct angle, resulting in over-grinding that causes denture deformation or surface damage. At the same time, it cannot protect metal components (such as clasps and rests), and the occlusal morphology of the artificial teeth cannot be guaranteed during grinding. Excessive grinding of cusps or pits and fissures affects chewing efficiency.

[0005] Therefore, a denture grinding and finishing device was proposed to solve the problems mentioned above. Summary of the Invention

[0021] Compared with the prior art, the beneficial effects of this invention are as follows: This denture grinding and finishing device, through the elastic force of the protective spring, can support the denture grinding surface with the protective bracket and the tilting protective frame, avoiding the phenomenon that the grinding head will wobble slightly during denture grinding, thus affecting the grinding force and angle, and causing over-grinding that leads to denture deformation or surface damage. The user lies on the bottom of the operating box in a reclining chair, and the head is fixed by the reinforced rubber clamp. The operator can manually operate the device through the operating rubber sleeve to perform minor grinding and finishing of the denture, improving the comfort of denture use. The specific details are as follows:

[0022] 1. By setting up a grinding and dressing mechanism, not only can the switching adjustment motor drive the switching adjustment disc and the fixed sleeve to rotate, but the angle of the grinding head can also be adjusted. Different grinding heads can be switched according to the grinding needs of the denture. Simultaneously, the cleaning brush can be switched to remove dust generated during grinding on 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 mounting sleeve, when the mounting blocks move to the horizontal rotation groove, the grinding connecting shaft is rotated horizontally, causing the mounting blocks to rotate horizontally within the horizontal rotation groove, allowing the mounting blocks to pass over the spring limit block, thereby locking the mounting blocks. For easy and quick installation and removal of the grinding connection shaft and grinding head, precise control of the grinding head is required when grinding dentures, as the surfaces to be ground are not flat and the cusps and fissures of the teeth need to be ground. The protective spring's elasticity supports the grinding surface of the denture, preventing slight wobbling of the grinding head that could affect the grinding force and angle, leading to over-grinding and denture deformation or surface damage. When polishing is required, increasing the downward pressure on the inclined surface of the inclined protective frame... Under the action of the inclined protective frame, the polishing surface of the grinding head is exposed, allowing for polishing after denture grinding. The protective bracket and inclined protective frame reduce the amplitude of the grinding head due to improper operation during denture grinding, thus improving the stability of denture grinding and enabling stable grinding and polishing, reducing the defect rate. During denture grinding, the suction force generated by the vacuum fan draws the grinding powder into the vacuum box through the ring-shaped suction nozzle. The first and second dust filters work together to filter the polishing dust. By opening... The mounting cover allows for cleaning of the first and second dust filters. The telescopic protective cover's telescopic action enhances dust absorption efficiency. Starting the rotating motor drives the rotating worm gear, and the meshing connection between the worm gear and the worm wheel causes the second adjusting disc to rotate, facilitating grinding head angle adjustment. Simultaneously, starting the second adjusting motor drives the first adjusting threaded rod, which in turn moves the first electric telescopic rod, adjusting the grinding head position. The first electric telescopic rod also allows for grinding head height adjustment, facilitating all-around grinding of the denture.

[0023] 2. By setting up a fixed support mechanism, operators can easily observe the denture grinding process through a viewing window. Simultaneously, workers can extend their arms into the operating rubber sleeve for manual operation, enabling manual grinding of complex areas of the denture and improving the grinding effect. Utilizing the sliding connection between the moving slide and the moving slider, the fixing plate can be moved out from the bottom of the operating box. During the movement of the fixing plate, the inclined section of the moving slide lowers the fixing plate. Simultaneously, rotating the lever drives the installation rotating disk to rotate. The sliding connection between the clamping block and the spiral limiting bracket allows the clamping block to move relative to the clamping sliding sleeve and clamping sliding frame, facilitating the clamping and fixing of the denture. Rotating the first adjustment knob drives the second adjustment threaded rod to adjust the spacing between the denture fixing blocks. The relative positioning mechanism can clamp and fix not only individual dentures but also complete dentures, facilitating denture polishing. Rotating the second adjustment knob drives the adjustment lever and bevel gear transmission assembly, which in turn drives the lifting threaded rod. Simultaneously, the lifting threaded sleeve drives the lifting lever and adjustment support plate. Rotating the support and the second electric telescopic rod allows the movement of the reinforcing rubber clamp, reinforcing both sides of the denture and improving the stability of denture polishing. When the user needs minor polishing, the fixing plate can be removed from the bottom of the control box. The user can lie on the bottom of the control box in a reclining chair, with their head secured by the reinforcing rubber clamp. The operator can then manually polish and adjust the denture using the operating rubber sleeve, enhancing user comfort. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-3 The present invention provides a technical solution: a denture grinding and finishing device, including a grinding and finishing mechanism 1 and a mounting top plate 120 installed on the top of the grinding and finishing mechanism 1. A fixed support mechanism 2 is provided at the bottom of the grinding and finishing mechanism 1, and a reinforcing bracket 223 is symmetrically arranged inside the fixed support mechanism 2. The grinding and finishing mechanism 1 includes a switching adjustment bracket 101. A switching adjustment motor 102 is fixedly installed on one side of the switching adjustment bracket 101. A switching adjustment disk 103 is fixedly connected to the output end of the switching adjustment motor 102. A fixed support plate 103 is fixedly installed around the switching adjustment disk 103. A fixed sleeve 104 is provided, in which a grinding motor 105 is fixedly installed. The output end of the grinding motor 105 is fixedly connected to a first fixed plate 106, which is rotatably connected to the fixed sleeve 104. Mounting springs 107 are fixedly installed around the bottom of the first fixed plate 106. A mounting sleeve 108 is fixedly installed at the bottom of the mounting springs 107. Vertical slots 109 are symmetrically formed inside the mounting sleeve 108, and horizontal rotation grooves 110 are symmetrically formed in the middle of the mounting sleeve 108. The two horizontal rotation grooves 110 are located at the center of the sleeve. A spring-loaded limit block 111 is fixedly installed in the part. Two horizontal rotating slots 110 are slidably connected to mounting blocks 112. A grinding connecting shaft 113 is fixedly installed between the two mounting blocks 112. A second fixing plate 114 is fixedly installed on the outer side of the grinding connecting shaft 113. A grinding head 115 is fixedly installed at the bottom of the grinding connecting shaft 113. The switching adjustment motor 102 drives the switching adjustment plate 103 and the fixing sleeve 104 to rotate, which not only allows for angle adjustment of the grinding head 115 but also allows for switching between different grinding heads 115 according to the grinding needs of the denture. The cleaning brush can be switched to clean the dust generated during the grinding of the denture surface. By aligning the mounting blocks 112 on both sides of the grinding connecting shaft 113 with the vertical slot 109 and inserting them into the mounting sleeve 108, when the mounting blocks 112 move to the horizontal rotation groove 110, the grinding connecting shaft 113 is rotated horizontally, causing the mounting blocks 112 to rotate horizontally inside the horizontal rotation groove 110, so that the mounting blocks 112 pass over the spring limit block 111, thereby locking the mounting blocks 112, which facilitates the quick installation and removal of the grinding connecting shaft 113 and the grinding head 115.

[0038] Please see Figures 3-6The bottom of the second fixed plate 114 is rotatably connected to the first rotating plate 116. Protective springs 117 are fixedly installed around the bottom of the first rotating plate 116. A protective bracket 118 is fixedly installed at the bottom of the protective springs 117. An inclined protective bracket 119 is fixedly installed at the bottom of the protective bracket 118. A dust collection box 121 is fixedly installed on the top of the mounting plate 120. A mounting cover 122 is threadedly connected to the top of the dust collection box 121. A dust collection fan 123 is fixedly installed on the top of the mounting cover 122. A first dustproof net 124 is fixedly installed at the bottom of the mounting cover 122. A second dustproof net 125 is fixedly installed inside the mounting cover 122 near the first dustproof net 124. A dust collection tray 126 is placed inside the bottom of the dust collection box 121. A first connecting pipe 127 is symmetrically installed on both sides of the denture. A second connecting pipe 128 is fixedly installed at the ends of the two first connecting pipes 127. An annular suction nozzle 129 is fixedly installed between the two second connecting pipes 128. A telescopic protective cover 130 is fixedly installed inside the annular suction nozzle 129. The telescopic protective cover 130 is fixedly installed on the top of the switching adjustment bracket 101. A third fixing plate 131 is fixedly installed at the bottom center of the mounting top plate 120. When grinding the denture, since the surface to be ground is not flat, and the cusps and pits of the denture need to be ground, the grinding head 115 needs to be precisely controlled. Through the elastic force of the protective spring 117, the protective bracket 118 and the tilting protective bracket 119 can be adjusted to support the denture. The grinding surface is supported to prevent slight wobbling of the grinding head 115 during denture grinding, which could affect the grinding force and angle, causing over-grinding and resulting in denture deformation or surface damage. When polishing is required, increasing the downward pressure, under the action of the inclined protective frame 119, causes the inclined protective frame 119 to rise, exposing the polishing surface of the grinding head 115 for polishing. The protective bracket 118 and the inclined protective frame 119 reduce the amplitude of the grinding head 115 due to improper operation during denture grinding, thereby improving the stability of denture grinding. This ensures stable grinding and polishing of the denture, reducing the defect rate. The suction force generated by the vacuum fan 123 draws polishing powder into the dust collection box 121 through the annular suction nozzle 129. The first dust filter 124 and the second dust filter 125 work together to filter the polishing dust. The first dust filter 124 and the second dust filter 125 can be cleaned by opening the mounting cover 122. The telescopic protective cover 130 further enhances dust absorption efficiency. While existing technologies use motors to adjust the angle and height of the polishing equipment, some wobbling occurs during movement. Since the polishing surface of dentures has a significant curvature, even slight changes in amplitude can affect the surface polishing of the denture.This can affect the final result of denture preparation.

[0039] Please see Figures 6-7 A rotating bracket 132 is fixedly installed on one side of the bottom of the third fixed plate 131. A rotating motor 133 is fixedly installed on the outside of the rotating bracket 132. A rotating worm gear 134 is fixedly connected to the output end of the rotating motor 133.

A first electric motor is fixedly installed at the bottom of the adjusting threaded sleeve 139. The first electric telescopic rod 140 is fixedly installed on the top of the telescopic protective cover 130. By starting the rotating motor 133, the rotating worm gear 134 is driven to rotate. Utilizing the meshing connection between the rotating worm gear 134 and the rotating worm wheel 135, the second adjusting disc 136 is rotated, which facilitates the angle adjustment of the grinding head 115. At the same time, starting the second adjusting motor 137 drives the first adjusting threaded rod 138 to rotate, which causes the adjusting threaded sleeve 139 to move the first electric telescopic rod 140, thereby adjusting the position of the grinding head 115. The height of the grinding head 115 can also be adjusted through the first electric telescopic rod 140, which facilitates all-round grinding of the denture.

At the same time, the operator can extend their arm into the operating rubber sleeve 204 to perform manual operation, which can be used for complex parts of the denture. Manual polishing is performed to improve the polishing effect of the denture.

A rotating support 231 is fixedly installed at the center of one side of the adjusting support plate 230. A second electric telescopic rod 232 is rotatably connected to the outer side of the rotating support 231. A reinforcing bracket is fixedly installed at the end of the second electric telescopic rod 232. The rubber clamp 233, by rotating the first adjusting knob 221, drives the second adjusting threaded rod 220 to rotate, thereby adjusting the relative position between the denture fixing blocks 222. This allows for clamping and fixing not only a single denture but also complete dentures, facilitating denture grinding. Rotating the second adjusting knob 224 drives the adjusting rotating rod 225 and the bevel gear transmission assembly 226 to rotate, which in turn drives the lifting threaded rod 227 to rotate. Simultaneously, the lifting threaded sleeve 228 drives the lifting rotating rod 229 and the adjusting support plate 230. The rotation of the support 231 and the second electric telescopic rod 232 allows the movement of the reinforcing rubber clamp 233, which can reinforce both sides of the denture and improve the stability of the denture grinding. At the same time, when the denture user needs to perform light grinding on the denture, the fixing plate 208 can be removed from the bottom of the operation box 202. The user can lie on the bottom of the operation box 202 in a reclining chair and use the reinforcing rubber clamp 233 to fix the head. The operator can manually operate the operation through the operating rubber sleeve 204 to perform light grinding and trimming on the denture, improving the comfort of denture use.

[0042] Working principle: Before using this denture grinding and finishing device, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 11As shown, firstly, the viewing window 203 allows the operator to easily observe the polishing process of the denture. Simultaneously, the operator can extend their arm into the operating rubber sleeve 204 for manual operation, enabling manual polishing of complex areas of the denture and improving the polishing effect. Utilizing the sliding connection between the movable slide 205 and the movable slider 206, the fixing plate 208 can be moved out from the bottom of the operating box 202. Simultaneously, the fixing plate 208 descends under the action of the inclined section of the movable slide 205. At the same time, rotating the lever 215 drives the mounting rotating disk 214 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 relative to each other, facilitating the clamping and fixing of the denture. Rotating the first adjusting knob 221 drives the second adjusting threaded rod 220 to rotate, adjusting the distance between the denture fixing blocks 222. The relative position allows for clamping and fixing not only individual dentures but also complete dentures, facilitating denture polishing. Rotating the second adjustment knob 224 drives the adjustment rotating rod 225 and the bevel gear transmission assembly 226 to rotate, which in turn drives the lifting threaded rod 227. Simultaneously, the lifting threaded sleeve 228 drives the lifting rotating rod 229 and the adjustment support plate 230 to rotate. Rotating the support 231 and the second electric telescopic rod 232 allows the movement of the reinforcing rubber clamp 233, reinforcing both sides of the denture and improving the stability of denture polishing. When the denture user needs minor polishing, the fixing plate 208 can be removed from the bottom of the operating box 202. The user can lie on the bottom of the operating box 202 in a reclining chair, securing their head with the reinforcing rubber clamp 233. The operator can then manually polish and adjust the denture using the operating rubber sleeve 204, improving the comfort of denture use.

[0043] Secondly, by using the switching adjustment motor 102 to drive the switching adjustment disc 103 and the fixed sleeve 104 to rotate, not only can the angle of the grinding head 115 be adjusted, but different grinding heads 115 can also be switched according to the grinding needs of the denture. Simultaneously, the cleaning brush can be switched to clean the dust generated during grinding on the denture surface. By aligning the mounting blocks 112 on both sides of the grinding connecting shaft 113 with the vertical slot 109 and inserting them into the mounting sleeve 108, when the mounting blocks 112 move to the horizontal rotation groove 110, the grinding connecting shaft 113 is rotated horizontally, causing the mounting blocks 112 to rotate horizontally within the horizontal rotation groove 110. This allows the mounting blocks 112 to pass over the spring limit block 111, thereby locking the mounting blocks 112 and facilitating the movement of the grinding connecting shaft 113 and the grinding head. The quick installation and removal of the grinding head 115 is crucial during denture grinding. Since the surface to be ground is not flat, and the cusps and fissures of the denture need to be ground, precise control of the grinding head 115 is required. The elastic force of the protective spring 117 allows the protective bracket 118 and the tilting protective bracket 119 to support the denture grinding surface, preventing slight shaking of the grinding head 115 during denture grinding. This avoids affecting the grinding force and angle, causing over-grinding that could lead to denture deformation or surface damage. When polishing is required, increasing the downward pressure causes the tilting protective bracket 119 to rise under the action of its tilted surface, exposing the polishing surface of the grinding head 115 for post-grinding polishing.

[0044] The protective bracket 118 and the tilting protective bracket 119 reduce the amplitude of the grinding head 115 due to improper operation during denture grinding, thereby improving the stability of denture grinding. This allows for stable grinding and polishing of the denture, reducing the defect rate. During denture grinding, the suction force generated by the vacuum fan 123 draws the grinding powder into the vacuum box 121 through the annular suction nozzle 129. The first dust filter 124 and the second dust filter 125 work together to filter the polishing dust. The first dust filter 124 and the second dust filter 125 can be cleaned by opening the mounting cover 122. The telescopic protective cover 130 can better absorb dust and improve the efficiency of dust absorption. By starting the rotating motor 133, the rotating worm 134 is driven to rotate. Utilizing the meshing connection between the rotating worm 134 and the rotating worm wheel 135, the second adjusting plate 136 is rotated, which facilitates the angle adjustment of the grinding head 115. At the same time, starting the second adjusting motor 137 drives the first adjusting threaded rod 138 to rotate, which causes the adjusting threaded sleeve 139 to move the first electric telescopic rod 140, which can adjust the position of the grinding head 115. At the same time, the height of the grinding head 115 can be adjusted through the first electric telescopic rod 140, which facilitates all-round grinding of the denture.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
