Abstract
Description
Technical Field
[0001] This invention relates to the field of grinding equipment technology, and more specifically to a precision grinding and processing equipment for dentures with adaptive occlusal pressure detection. Background Technology
[0002] Dental prosthesis fabrication is the process of creating artificial teeth to replace missing natural teeth using specialized techniques and processes, based on the patient's oral condition. Its purpose is to restore the patient's chewing function, speech ability, and facial aesthetics. Dental prosthesis fabrication is divided into custom-made complete dentures, custom-made fixed dentures, and custom-made removable partial dentures.
[0003] Chinese patent CN213439043U discloses a liquid environment polishing machine for dental prosthesis processing. Two sets of electric motors drive turbine blades to rotate the liquid inside the acceleration cylinders at high speed, generating sufficient centrifugal force. Because the two acceleration cylinders are truncated cones, the centrifugal force generated by both sets of cylinders acts on the main working cylinder and the auxiliary working cylinder. During use, abrasive media such as quartz sand are placed inside the hopper. Then, the threaded rod is rotated to bring the main and auxiliary working cylinders closer together and seal them. After the liquid fills both acceleration cylinders, it passes through the liquid level column. Under the action of centrifugal force, the quartz sand inside the hopper, along with the high-speed rotating water flow, irregularly washes the dental prosthesis. The surface smoothness of the dental prosthesis gradually increases under the action of the water flow. The operation is highly efficient, and the prosthesis can be directly removed and used after the operation is completed.
[0004] When using the aforementioned liquid environment polishing machine for denture processing, the dental ring blank to be processed needs to be placed on the grinding disc, pushed between a pair of rollers, and the motor is turned on to start the grinding disc for processing. The manual feeding operation by the worker is slow, which can easily lead to a decrease in production efficiency when large-scale processing is required. Furthermore, the equipment may cause problems when grinding the dental ring blank, and manual operation can easily cause worker injury, especially near the high-speed rotating grinding process.

[0014] In a preferred embodiment of the precision grinding and processing equipment for adaptive occlusal pressure detection of the denture described in this invention, a lead screw is fixedly connected to the upper surface of the bevel gear two. The end of the lead screw away from the bevel gear two is rotatably connected to the lifting frame. The lifting frame is fixedly installed at one end of the sliding rack two. The lifting frame is fixedly connected to one end of the material distribution plate. One end of the material distribution plate is screwed to the lead screw. A motor is connected to the end of the limiting rod away from the sliding rack two. The motor is fixedly installed in the placement box.
[0015] To achieve the above objectives, the present invention provides the following technical solution: a precision grinding and machining equipment for dentures with adaptive occlusal pressure detection, comprising the following steps: First, the toothed ring blanks are placed from the placement port between the stacking plates for stacking. The rotating rollers inside the grinding chamber rotate counterclockwise, causing the conveyor belts attached to the rollers at both ends to move. This moves the placement trays on the conveyor belts in an orderly manner within the grinding chamber. As the conveyor belt carries the placement trays along the inclined edge between the two drive sliders, it gradually pushes the drive sliders to both sides. At the same time, the driven gear on the lower surface of the placement tray engages with the drive rack on the support frame. The clockwise rotation of the driven gear drives the positioning and locking components on the placement trays to retract to the center position. As the drive sliders move to both sides, the intermittent feeding components inside the placement chamber operate, causing the moving plates on both sides and the drive sliders to move to both sides simultaneously, feeding a single toothed ring blank into the placement tray below.
[0016] The technical solution provided by this invention has the following advantages compared with the known prior art: 1. By placing the toothed ring blanks between the stacking plates, the blanks push the stacking plates on both sides to move to the sides, compressing the annular springs to adapt to different sizes of toothed ring blanks. Stacking the toothed ring blanks between the stacking plates can better adapt to different shapes and sizes, improve the stability and accuracy of clamping, and handle toothed blanks of various sizes, thereby improving production efficiency. By driving the placement trays on the conveyor belt to transport them in an orderly manner within the grinding chamber, the placement trays come into contact with the drive sliders on both sides, driving the intermittent feeding component to intermittently and individually drop the stacked toothed ring blanks into the placement trays. Through orderly conveying, waiting time can be reduced, ensuring continuous operation of the grinding equipment and improving overall production efficiency.
[0017] 2. After the placement tray containing the toothed ring blank passes between the drive sliders, the drive rack no longer meshes with the driven gear. The taut folding spring will pull the limit slider along the directional slide under the reaction force, so that the three positioning blocks move out of the storage cover at the same time and abut against the inner ring wall of the toothed ring blank in the placement tray. This allows the toothed ring blank to be positioned and calibrated in the placement tray. Accurate positioning and calibration can ensure that the toothed ring blank is in the correct position, thereby improving the processing quality of the toothed ring blank and effectively preventing the toothed ring blank from accidentally falling off during the feeding process.
[0018] 3. The output end of the motor drives the first bevel gear on the limit rod to rotate, which in turn drives the second bevel gear to rotate the lead screw in the lifting frame. This drives the material distribution plate, which is screwed to the lead screw, to adjust the lifting height. The linkage rod at one end of the sliding rack drives the sliding shaft to slide in the adjusting groove, so that the interval between the material distribution plate and the moving plate is the same as the height of the toothed ring blank. Adjusting according to the size of the toothed ring blank can ensure that the feeding component is perfectly matched with the toothed ring blank, and can quickly adapt to toothed ring blanks of different sizes, reducing changeover time.
[0019] 4. By expanding the movable plate inside the placement box to both sides, the movable plate moves the sliding rack on one side. The movement of the sliding rack causes the meshing coordinating gear above to rotate. The rotation of the coordinating gear pushes the sliding rack to insert the material distribution plate into the chamfer of the toothed ring blank port, separating the stacked toothed ring blanks from the bottom toothed ring blank that is about to be unloaded. Intermittent unloading can effectively avoid collisions and damage caused by unloading multiple pieces at the same time, protecting the integrity of the toothed blanks. Single unloading can ensure more accurate positioning and placement of each toothed blank, improving the convenience of subsequent processing. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0024] The present invention will be further described below with reference to embodiments. Example 1
[0025] Reference Figures 1-5 , Figure 7This invention provides a precision grinding and machining device for dentures with adaptive occlusal pressure detection, comprising a grinding and machining chamber 100. The device is characterized by a positioning and feeding mechanism 200 within the grinding and machining chamber 100. The positioning and feeding mechanism 200 includes rotating rollers 201 rotatably connected to both sides of the inner wall of the grinding and machining chamber 100. Conveyor belts 202 are sleeved on the rotating rollers 201 at both ends of the grinding and machining chamber 100. Placement trays 203 are fixedly connected to the conveyor belts 202 at intervals. There is a gap between the two conveyor belts 202, which are connected by the spaced placement trays 203. The grinding and machining process... A support frame 204 is fixedly installed on one side of the inner wall of the tool box 100. A drive rack 205 is fixedly connected to the side of the support frame 204 away from the inner wall of the grinding tool box 100. The drive rack 205 is located on one side of the conveyor belt 202. A driven gear 206 is rotatably connected to the lower surface of the placement tray 203. The driven gear 206 is located in the gap between the two conveyor belts 202. A positioning and locking component is fixedly connected to the driven gear 206. The positioning and locking component is installed in the placement tray 203. The drive rack 205 and the driven gear 206 mesh together and can drive the positioning and locking component in the placement tray 203 to be retracted. An intermittent feeding mechanism 300 is fixedly installed at one end of the grinding chamber 100. The intermittent feeding mechanism 300 includes a placement box 301 fixedly installed on one side of the grinding chamber 100. A placement opening 302 is provided on the upper surface of the placement box 301. Annular springs 303 are fixedly installed on both sides of the inner wall of the placement box 301. A stacking plate 304 is fixedly installed at the end of the annular spring 303 away from the placement box 301. The stacking plate 304 is located below the placement opening 302. A toothed ring blank 305 is stacked between the stacking plates 304. The stacking plates 304 on both sides limit the stacking of the toothed ring blank 305 placed in the middle. An intermittent feeding assembly is provided inside the placement box 301. The intermittent feeding assembly is located within the toothed ring blank 305. Below 5, the intermittent feeding assembly includes a movable plate 306 slidably connected inside the placement box 301. A drive slider 307 is fixedly connected to the lower surface of the movable plate 306. The lower surfaces of the drive sliders 307 on both sides slide against the upper surface of the conveyor belt 202. The conveyor belt 202 drives the placement plate 203 to pass between the drive sliders 307, which will drive the toothed ring blank 305 to be fed from the movable plate 306. There are four rotating rollers 201, which are symmetrically installed on the inner wall of the grinding box 100. The middle part of the conveyor belt 202 is a hollow part. The two conveyor belts 202 are fixed together by the placement plate 203. The upper and lower ends of the toothed ring blank 305 are chamfered to facilitate subsequent intermittent feeding.
[0026] Specifically, the toothed ring blank 305 is placed from the placement port 302 between the stacking plates 304 for stacking. The rotating rollers 201 inside the grinding chamber 100 rotate counterclockwise, causing the conveyor belts 202 fitted onto the rollers 201 to move. This moves the placement trays 203 on the conveyor belts 202, transporting them orderly within the grinding chamber 100. As the conveyor belts 202 carry the placement trays 203 along the inclined sides between the driving sliders 307, they gradually push the driving sliders 307 towards... Pushing from both sides, the driven gear 206 on the lower surface of the placement tray 203 engages with the drive rack 205 on the support frame 204. The clockwise rotation of the driven gear 206 drives the positioning and locking components on the placement tray 203 to retract to the center position. As the drive slider 307 moves to both sides, it drives the intermittent feeding component in the placement box 301 to operate, causing the moving plates 306 on both sides and the drive slider 307 to move to both sides simultaneously, feeding a single toothed ring blank 305 into the placement tray 203 below.
[0027] By placing the toothed ring blank 305 between the stacking plates 304, the toothed ring blank 305 pushes the stacking plates 304 on both sides to move to the sides, squeezing the annular spring 303 to adapt to toothed ring blanks 305 of different sizes. Stacking the toothed ring blanks 305 between the stacking plates 304 can better adapt to different shapes and sizes, improve the stability and accuracy of clamping, and handle toothed blanks of various sizes, thereby improving production efficiency. By driving the placement tray 203 on the conveyor belt 202 to transport the toothed ring blanks 305 in an orderly manner within the grinding chamber 100, the placement tray 203 contacts the drive sliders 307 on both sides, driving the intermittent feeding component to intermittently and individually drop the stacked toothed ring blanks 305 into the placement tray 203. Through orderly conveying, waiting time can be reduced, ensuring continuous operation of the grinding equipment and improving overall production efficiency. Example 2
[0028] Reference Figures 5-6 In the second embodiment of the present invention, a precision grinding and processing device for dentures with adaptive occlusal pressure detection is provided. The positioning and locking component includes a rotating seat 207 fixedly connected to the driven gear 206, a limiting ring 208 fixedly connected to the rotating seat 207, the rotating seat 207 being rotatably connected to the center of the placement plate 203, the limiting ring 208 being slidably connected inside the placement plate 203, a limiting groove 209 being formed around the placement plate 203, the bottom end of the rotating seat 207 being fixedly connected to the driven gear 206, and the limiting ring 208 being fixedly connected to the outer wall of the rotating seat 207.
[0029] A limiting ring 208 is slidably connected inside the limiting groove 209. A transmission rod 210 is rotatably connected to the upper surface of the rotating seat 207. There are three transmission rods 210. A positioning block 211 is rotatably connected to the end of the transmission rod 210 away from the rotating seat 207. A limiting slider 212 is fixedly connected to the lower surface of the positioning block 211. The shapes of the limiting ring 208 and the limiting groove 209 fit each other, so that the rotating seat 207 will not fall off at the center of the placement plate 203. There are three transmission rods 210, and the number of the connected positioning blocks 211 and limiting sliders 212 is also the same. One end of the transmission rod 210 is rotatably connected between the positioning block 211 and the limiting slider 212.
[0030] The placement tray 203 has a directional groove 213, and the limiting slider 212 is slidably connected in the directional groove 213. The upper surface of the limiting slider 212 is slidably connected to the lower surface of the transmission rod 210. A folding spring piece 214 is fixedly installed at one end of the limiting slider 212. A storage cover 215 is fixedly installed on the upper surface of the placement tray 203. The transmission rod 210 can drive the positioning block 211 to move in the storage cover 215. There are also three directional grooves 213. The positioning block 211 is limited by the limiting slider 212 and the directional groove 213. The folding spring piece 214 is installed at the top of the limiting slider 212. The storage cover 215 has a through groove corresponding to the position of the transmission rod 210, so that the positioning block 211 can smoothly enter the storage cover 215.
[0031] Specifically, when the driven gear 206 on the lower surface of the placement tray 203 is driven by the conveyor belt 202 to engage with the drive rack 205 on the support frame 204, the driven gear 206 will drive the rotating seat 207 to rotate clockwise at the center of the placement tray 203. The limiting ring 208 on the rotating seat 207 will slide in the limiting groove 209. At the same time, the rotation will drive the transmission rod 210 on the upper surface of the rotating seat 207 to pull the limiting slider 212 outside the storage cover 215 to slide in the directional groove 213. When the limiting slider 212 slides along the directional groove 213 into the storage cover 215, it will pull the folding spring piece 214 on one side of the limiting slider 212 to a taut state, so that the positioning block 211 above the limiting slider 212 will be retracted into the storage cover 215. At the same time, the placement tray 203 will move completely to the center of the drive slider 307. The intermittent feeding assembly lowers the toothed ring blank 305 into the placement tray 203. After the conveyor belt 202 drives the placement tray 203 containing the toothed ring blank 305 through the drive slider 307, the drive rack 205 no longer meshes with the driven gear 206. The taut folding spring 214, under the reaction force, pulls the limiting slider 212 to slide along the directional slide groove 213, causing the three positioning blocks 211 to move out of the storage cover 215 at the same time, and simultaneously abut against the inner ring wall of the toothed ring blank 305 in the placement tray 203, so that the position of the toothed ring blank 305 in the placement tray 203 is positioned and calibrated, and the toothed ring blank 305 in the placement tray 203 is limited. The toothed ring blank 305 is transported to the grinding chamber in the grinding processing box 100 by the conveyor belt 202, and the toothed ring blank 305 on the placement tray 203 is processed by the grinding equipment. Example 3
[0032] Reference Figures 7-10 In the third embodiment of the present invention, a precision grinding and processing device for dentures with adaptive occlusal pressure detection is provided. The intermittent feeding component further includes a sliding rack 308 fixedly connected to one side of the moving plate 306. The lower surface of the sliding rack 308 is slidably connected to the inner wall of the placement box 301. A coordinating gear 309 is meshed above the sliding rack 308. A sliding rack 310 is meshed on the side of the coordinating gear 309 away from the sliding rack 308. The coordinating gear 309 is rotatably connected in the placement box 301, and the sliding rack 310 is slidably connected in the placement box 301.
[0033] A material distribution plate 311 is provided on the sliding rack 310. A toothed ring blank 305 is slidably connected to the material distribution plate 311. A linkage rod 312 is rotatably connected to the left end of the sliding rack 310. One side of the linkage rod 312 is slidably connected to the inner wall of the placement box 301. A sliding shaft 313 is fixedly connected to the end of the linkage rod 312 away from the sliding rack 310. The shape of the material distribution plate 311 is an extended T-shape, with one end inclined. The thickness of the base below the material distribution plate 311 is the same as that of the sliding rack 310.
[0034] The left end of the material distribution plate 311 is provided with an adjustment groove 314. The sliding shaft 313 at one end of the linkage rod 312 is slidably connected in the adjustment groove 314. The end of the sliding rack 310 away from the linkage rod 312 is provided with a storage groove 315. There are two linkage rods 312 on one sliding rack 310. The other end of the linkage rod 312 is slidably connected to the material distribution plate 311.
[0035] A limiting rod 316 is slidably connected inside the storage slot 315. A bevel gear 317 is provided on the limiting rod 316. A bevel gear 318 meshes above the bevel gear 317. The bevel gear 317 is rotatably connected to one end of the sliding rack 310. Grooves are provided on both sides of the limiting rod 316. Protrusions are fixedly connected to both sides of the central hole of the bevel gear 317. When the limiting rod 316 rotates, the bevel gear 317 can be driven to rotate simultaneously through the cooperation of the grooves and protrusions. When the sliding rack 310 moves, the limiting rod 316 can slide through the central hole of the bevel gear 317.
[0036] A lead screw 319 is fixedly connected to the upper surface of the second bevel gear 318. The end of the lead screw 319 away from the second bevel gear 318 is rotatably connected to the lifting frame 320. The lifting frame 320 is fixedly installed at one end of the second sliding rack 310. The lifting frame 320 is fixedly connected to one end of the material distribution plate 311. One end of the material distribution plate 311 is screwed to the lead screw 319. A motor 321 is connected to the end of the limiting rod 316 away from the second sliding rack 310. The motor 321 is fixedly installed in the placement box 301.
[0037] Specifically, the output of motor 321 drives the bevel gear 317 on the limit rod 316 to rotate, causing the meshing bevel gear 318 to drive the lead screw 319 to rotate within the lifting frame 320. This causes the material distribution plate 311, which is screwed to the lead screw 319, to adjust its lifting height. The linkage rod 312 at one end of the sliding rack 310 drives the sliding shaft 313 to slide within the adjusting groove 314, making the gap between the material distribution plate 311 and the moving plate 306 the same as the height of the toothed ring blank 305. When the rotating roller 201 drives the placement plate 203 on the conveyor belt 202 to pass between the two driving sliders 307, the placement plate 203 will move along the inclined side of the driving slider 307, thus moving the driving slider 307. As the slider 307 is gradually pushed to both sides, it will cause the moving plate 306 inside the placement box 301 to expand to both sides. As the moving plate 306 moves, it will also cause the sliding rack 308 on one side to move together. The movement of the sliding rack 308 will cause the meshing coordination gear 309 above to rotate. The rotation of the coordination gear 309 will push the sliding rack 310 to drive the material distribution plate 311 to insert into the chamfer of the end of the toothed ring blank 305, separating the stacked toothed ring blank 305 from the bottom toothed ring blank 305 that is about to be unloaded. The toothed ring blank 305 located between the material distribution plate 311 and the moving plate 306 completes a single intermittent unloading when the moving plate 306 expands to both sides.

[0038] Reference Figures 1-5 , Figure 7 This is the fourth embodiment of the present invention, which provides a precision grinding and machining equipment for dentures with adaptive occlusal pressure detection, comprising: First, the tooth ring blanks 305 are placed from the placement opening 302 between the stacking plates 304 for stacking. The rotating rollers 201 inside the grinding chamber 100 rotate counterclockwise, causing the conveyor belts 202 attached to the rollers 201 to move. This moves the placement trays 203 on the conveyor belts 202, transporting them orderly within the grinding chamber 100. As the conveyor belts 202 carry the placement trays 203 along the inclined sides between the drive sliders 307, they gradually push the drive sliders 307 towards the sides... The side push, and at the same time, the driven gear 206 on the lower surface of the placement plate 203 will contact and mesh with the drive rack 205 on the support frame 204. The clockwise rotation of the driven gear 206 drives the positioning and locking component on the placement plate 203 to retract to the middle position. While the drive slider 307 moves to both sides, it will drive the intermittent feeding component in the placement box 301 to operate, so that the moving plates 306 on both sides and the drive slider 307 move to both sides at the same time, feeding a single tooth ring blank 305 into the placement plate 203 below.
