Description

Technical Field

[0001] The utility model relates to the technical field of denture processing equipment, in particular to a denture grinding device. Background Art

[0002] Grinding equipment is required in the production of dentures. Existing denture grinding devices, such as patent CN220783347U, discloses a denture grinding equipment. When positioning and installing the denture, the grinding equipment drives two clamping blocks to move relative to each other through a threaded rod, thereby clamping and fixing the denture. However, the following problems exist when using the equipment: when tightening the threaded rod, the clamping block on the threaded rod will also rotate with the threaded rod, and in the process of fixing the denture, the two clamping blocks will also fit with the side surfaces of the denture. Therefore, when the clamping block rotates, friction will be generated between the side surfaces of the denture, which increases the difficulty of moving the clamping block and is not conducive to the effective clamping of the denture. On the other hand, due to the rectangular shape of the clamping block, the contact surface between the clamping block and the denture is not tight when the user positions the denture, which makes the denture easy to loosen and fall off when being polished. Therefore, it is not convenient to stably position and clamp the denture during use, reducing the convenience of use. Utility Model Content

[0003] The purpose of the utility model is to provide a denture grinding device, which has the advantages of good fixing effect during denture grinding and is not easy to loosen. When grinding multiple end faces, the denture does not need to be manually disassembled and reassembled, and the denture grinding end faces can be adjusted, thereby improving the denture grinding efficiency.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a denture polishing device includes a workbench, the upper end surface of the workbench is provided with a mounting seat and two clamping assemblies symmetrically arranged on both sides of the mounting seat, the upper end of the mounting seat is provided with a placement groove for placing the denture, the clamping assembly includes a first telescopic cylinder and an arc-shaped clamping block, the first telescopic cylinder is installed on the mounting seat, the arc-shaped clamping block is installed on the telescopic shaft of the first telescopic cylinder, and the arc-shaped clamping block is located above the placement groove, and a rubber layer is provided on the opposite arc-shaped end surfaces of the two arc-shaped clamping blocks.

[0005] Furthermore, the mounting seat is cylindrical and includes a lower fixed part and an upper rotating part. The lower end of the fixed part is connected to the upper end surface of the workbench. A connecting shaft is provided at the axis center of the rotating part. The connecting shaft is inserted into the upper end surface of the fixed part and is rotatably connected through a bearing. The workbench is also provided with a steering assembly, which cooperates with the rotating part.

[0006] Furthermore, the steering assembly includes a second telescopic cylinder, which is installed on the upper end surface of the workbench. A transmission rack is provided on the telescopic shaft of the second telescopic cylinder, and a transmission gear is provided on the outer wall of the rotating part, which is adapted to mesh with the transmission rack.

[0007] Furthermore, a "7"-shaped support plate is vertically installed on the upper end surface of the workbench, and a guide rail is provided on the lower end surface of the horizontal side of the support plate. The guide rail is slidably connected to a sliding seat for installing the third telescopic cylinder.

[0008] Furthermore, a driving motor is installed on the side of the vertical side of the support plate, and the driving shaft of the driving motor is connected to a screw rod. The other end of the screw rod passes through the vertical side of the support plate and the sliding seat in sequence, and is rotatably connected to the horizontal side of the support plate, and the screw rod is threadedly adapted to the sliding seat.

[0012] When the two arc-shaped clamping blocks clamp the two sides of the denture, the curvature of the arc-shaped end faces can be adapted to the side faces of the denture as much as possible, which can improve the fitting rate between the clamping blocks and the side faces of the denture. At the same time, a rubber layer is arranged on the arc-shaped end faces. When the denture is clamped, the rubber layer will squeeze the side faces of the denture. Since the rubber material has a certain elasticity, the rubber layer will also produce a certain deformation, so that it can better fit the irregular side faces of the denture. After the rubber layer is deformed, it will also produce a rebound force, so that the rubber layer can further press the denture to ensure the stability of the denture during polishing. In addition, the arc-shaped clamping block realizes its horizontal movement through the extension and contraction of the first telescopic cylinder. No friction will be generated between the clamping block and the denture when it moves, which facilitates the movement of the arc-shaped clamping block and improves the convenience of use.

[0013] When the two end faces of the denture that are not clamped by the arc clamp are polished, the arc clamp can be slightly loosened to the denture. At this time, the denture is vertically located in the placement slot. Then start the second telescopic cylinder to move the transmission rack on it horizontally and drive the rotating part to rotate through the transmission gear, so that the denture can rotate and make the polished end faces of the denture face the arc clamp. Then start the first telescopic cylinder to allow the arc clamp to clamp the denture again and stabilize it. Therefore, when polishing multiple end faces of the denture, the device can adjust the polished end faces of the denture without manually disassembling and reassembling the denture, thereby improving the efficiency of denture polishing.

[0023] A denture polishing device comprises a workbench 1, the upper end surface of the workbench 1 is provided with a mounting seat 2 and two clamping assemblies symmetrically arranged on both sides of the mounting seat 2, the upper end of the mounting seat 2 is provided with a placement groove 3 for placing the denture, the clamping assembly comprises a first telescopic cylinder 4 and an arc-shaped clamping block 5, the first telescopic cylinder 4 is installed on the mounting seat 2, the arc-shaped clamping block 5 is installed on the telescopic axis of the first telescopic cylinder 4, and the arc-shaped clamping block 5 is located above the placement groove 3, and rubber layers 6 are provided on the opposite arc-shaped end surfaces of the two arc-shaped clamping blocks 5.

[0024] The workbench 1 is a metal tabletop, which can ensure the safety and stability during the denture grinding process; the placement groove 3 is a rectangular groove, and its length and width are slightly larger than the length and width of the lower part of the denture. When the lower part of the denture is placed in the placement groove 3, the rectangular placement groove 3 can prevent the denture from rotating in the placement groove 3, and initially realize the vertical and stable installation of the denture in the placement groove 3.

[0025] When the two arc-shaped clamping blocks 5 clamp the two sides of the denture, the curvature of the arc-shaped end faces can be adapted to the side faces of the denture as much as possible, which can improve the fitting rate between the clamping blocks 5 and the side faces of the denture. At the same time, a rubber layer 6 is arranged on the arc-shaped end faces. When the denture is clamped, the rubber layer 6 will squeeze the side faces of the denture. Since the rubber material has a certain elasticity, the rubber layer 6 will also produce a certain deformation, so that it can better fit the irregular side faces of the denture. After the rubber layer 6 is deformed, it will also produce a rebound force, so that the rubber layer can further press the denture to ensure the stability of the denture during polishing. In addition, the arc-shaped clamping block 5 realizes its horizontal movement through the extension and contraction of the first telescopic cylinder 4. No friction will be generated between it and the denture when it moves, which facilitates the movement of the arc-shaped clamping block 5 and improves the convenience of use.

[0026] Specifically, in this embodiment, the mounting seat 2 is cylindrical and includes a lower fixed portion 201 and an upper rotating portion 202. The lower end of the fixed portion 201 is connected to the upper end surface of the workbench 1. A connecting shaft is provided at the axis of the rotating portion 202. The connecting shaft is inserted into the upper end surface of the fixed portion 201 and is rotatably connected through a bearing 11. The workbench 1 is also provided with a steering assembly, which cooperates with the rotating portion 202.

[0027] The steering assembly includes a second telescopic cylinder 8, which is mounted on the upper end surface of the workbench 1. A transmission rack 9 is provided on the telescopic shaft of the second telescopic cylinder 8. A transmission gear 10 is provided on the outer wall of the rotating part 202. The transmission gear 10 is adapted to mesh with the transmission rack 9.

[0028] The fixing part 201 can be fixedly installed on the workbench 1 by welding, and the placement groove 3 is opened on the upper end surface of the rotating part 202. The rotating part 202 can realize 360° rotation around the axis. When the two end surfaces of the denture that are not clamped by the arc clamping block 5 are polished, the arc clamping block 5 can be slightly loosened from the denture. At this time, the denture is vertically located in the placement groove 3, and then the second telescopic cylinder 8 is started to allow the transmission rack 9 on it to move horizontally, and the rotating part 202 is driven to rotate through the transmission gear 10, so that the denture can rotate and the end surface of the denture that has been polished is facing the arc clamping plate 5, and then the first telescopic cylinder 4 is started to allow the arc clamping plate 5 to clamp the denture again for stability. Therefore, when the device is grinding multiple end surfaces of the denture, the denture can be adjusted without manually disassembling and reassembling the denture, thereby improving the efficiency of denture grinding.

[0029] It should be noted that when grinding the denture, the self-locking of the second telescopic cylinder 8 and the cooperation of the transmission rack 9 and the transmission gear 10 can prevent the rotating part 202 from rotating during grinding, thereby ensuring the stability of the denture during grinding.

[0030] Specifically, in this embodiment, a "7"-shaped support plate 12 is vertically installed on the upper end surface of the workbench 1, and a guide rail is provided on the lower end surface of the horizontal side of the support plate 12. The guide rail is slidably connected to a sliding seat 14 for installing a third telescopic cylinder 13. The third telescopic cylinder 13 is vertically telescopic, and the telescopic shaft of the third telescopic cylinder 13 is connected to a grinding motor 17, and a grinding head 18 is installed on the output shaft of the grinding motor 17.

[0031] The vertical side of the support plate 12 is fixedly mounted on the upper end surface of the workbench 1 by welding to ensure the overall stability of the support plate 12. The sliding seat 14 can slide left and right along the length direction of the horizontal side of the support plate 12, and then the horizontal direction of the grinding motor 17 and the grinding head 18 can be adjusted, so that the grinding head 18 can better adapt to the end surface of the grinding denture. The specific moving method is as follows: a driving motor 15 is installed on the side of the vertical side of the support plate 12, and the driving shaft of the driving motor 15 is connected with a screw 16. The other end of the screw 16 passes through the vertical side of the support plate 12 and the sliding seat 14 in turn, and is rotatably connected to the horizontal side of the support plate 12 through the bearing 11, and the screw 16 is threadedly adapted to the sliding seat 14. A guide rail is installed on the horizontal side of the support plate 12, and the sliding seat 14 is slidably mounted on the guide rail. The sliding direction of the sliding seat 14 is perpendicular to the connecting line direction of the two arc-shaped clamping blocks 5. The horizontal movement of the sliding seat 14 can be achieved by the positive and negative rotation of the driving motor 15 and the screw 16. The height of the grinding head 18 can be controlled by extending and retracting the third telescopic cylinder 13, and thus the grinding depth of the denture can be controlled.

[0032] Four supporting legs 7 are installed on the lower end surface of the workbench 1 , and the supporting legs 7 ensure the overall stability of the workbench 1 .

[0033] The working principle of this utility model:

[0034] When polishing the denture, first place the denture vertically into the placement slot 3, then start the first telescopic cylinder 4, let the arc-shaped clamp block clamp the left and right sides of the denture, and then adjust the position of the polishing head 18 by driving the motor 15, for example, let it face the front end face of the denture. After the polishing of the front end face of the denture is completed, adjust the height of the polishing head 18 by the third telescopic cylinder 13, and then move the polishing head 18 to the top of the denture to polish its upper end face, and then move it to face the rear end face of the denture. When the polishing of the front and rear end faces and the upper end face of the denture is completed, slightly loosen the arc-shaped clamp block 5, and rotate the rotating part 202 by the second telescopic cylinder 8, and rotate the left and right end faces of the denture to face the polishing head 18, thereby completing the polishing of the left and right end faces of the denture.
