Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis carving machine clamping technology, specifically a multi-functional clamping machine for dental prosthesis carving machines. Background Technology

[0002] Dentures, also known as false teeth, are made by carving disc ceramics using a dental prosthesis carving machine. Existing dental prosthesis carving machines have disc-shaped clamps. During the carving process, the clamps hold the disc ceramics in place to facilitate carving. After carving one disc ceramic, the worker needs to remove it and reinstall the next disc ceramic. However, in the existing technology, the clamps are fixed to the disc ceramics with bolts, which makes disassembly and assembly too strenuous. Therefore, we propose a multi-functional clamp for dental prosthesis carving machines. Utility Model Content

[0003] The purpose of this utility model is to provide a multi-functional fixture for a dental prosthesis carving machine to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional clamp for a dental prosthesis carving machine, comprising a connecting ring and a ceramic disc, wherein the outer wall of the ceramic disc is connected to a fixing ring, and the outer wall of the fixing ring is fitted and connected to the inner wall and top of the connecting ring, and a protruding ring is provided on the top of the fixing ring;

[0005] The connecting ring is provided with a rotating component, and the rotating component is provided with two driving components with the same structure.

[0006] Each drive component has two fixed blocks with the same structure, and the drive component is used to drive the two fixed blocks to move in opposite directions;

[0007] The bottom of each fixing block is attached to the fixing ring, and the fixing block is attached to the inner wall of the convex ring.

[0008] As a preferred embodiment of the multifunctional fixture for a dental prosthesis carving machine described in this utility model, the rotating component includes a bearing seat disposed on the top of a connecting ring, a rotating shaft rotatably connected to the bearing seat, a U-shaped connecting frame disposed on the rotating shaft, a micro motor disposed on the bearing seat, and the output shaft of the micro motor being connected to the rotating shaft.

[0009] As a preferred embodiment of the multifunctional fixture for a dental prosthesis carving machine described in this utility model, the driving component includes a fixed rod, on which a second micro motor is mounted, and a bidirectional lead screw is connected to the fixed rod via a bearing. The output shaft of the second micro motor is connected to the bidirectional lead screw, and sliders are screwed to both sides of the bidirectional lead screw. Slide grooves are provided on both sides of the bottom of the fixed rod, and the slide grooves on both sides are slidably connected to the sliders on both sides. The bottoms of the sliders on both sides are connected to the fixed blocks on both sides.

[0010] In a preferred embodiment of the multifunctional clamp for a dental prosthesis carving machine described in this utility model, the fixing rod is connected to the connecting frame.

[0011] As a preferred embodiment of the multifunctional clamp for a dental prosthesis carving machine described in this utility model, baffles are provided on the opposite sides of both sliders.

[0012] As a preferred embodiment of the multifunctional fixture for a dental prosthesis carving machine described in this utility model, the bottom of both side baffles is provided with sealing gaskets, and the bottom of the sealing gaskets on both sides respectively covers the sliding grooves on both sides.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By rotating the component, the fixing blocks can be driven to fit against the top of the fixing ring. Then, by driving the component, the two fixing blocks can move in opposite directions, so that all the fixing blocks around the ring fit against the inner wall of the convex ring, thus stably pressing the fixing ring. When disassembly is required, the fixing blocks can be removed by moving them away from the convex ring and the fixing ring one after the other. Compared with the existing technology that uses bolts to fix the ceramic disc, the disassembly and assembly efficiency is faster.

[0015] 2. By setting baffles and anti-slip pads, the rotation of the bidirectional lead screw is protected. When the slider moves, it can drive the baffles and anti-slip pads to move as well, which can work with the slider to block the groove and prevent the powder flying out during the ceramic disc engraving from entering the fixed rod through the groove and affecting the rotation of the bidirectional lead screw.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] As mentioned in the background section, this invention addresses the problem of laborious disassembly and assembly in existing technologies. It proposes a multi-functional clamp for a dental prosthesis carving machine.

[0022] Example 1

[0023] Reference Figures 1 to 3 A multi-functional clamp for a dental prosthesis carving machine includes a connecting ring 1 and a ceramic disc 2. The connecting ring 1 is used to connect to the carving machine. When the carving machine is carving, it drives the connecting ring 1 to adjust the angle to facilitate carving. The outer wall of the ceramic disc 2 is connected to a fixing ring 3. The outer wall of the fixing ring 3 is in close contact with the inner wall and top of the connecting ring 1. In the prior art, screws are generally set on the top of the fixing ring 3, but this requires the screws to be removed during disassembly. In order to improve the disassembly and assembly efficiency, a protruding ring 4 is set on the top of the fixing ring 3.

[0024] A rotating component is provided on the connecting ring 1, and two identical driving components are provided on the rotating component;

[0025] Each drive component is equipped with two fixed blocks 5 with the same structure, and the drive component is used to drive the two fixed blocks 5 to move in opposite directions;

[0026] The bottom of the fixing block 5 is attached to the fixing ring 3, and the fixing block 5 is attached to the inner wall of the convex ring 4, so that the fixing block 5 not only presses the fixing ring 3, but also limits the convex ring 4, thereby fixing the ceramic disc 2.

[0027] The rotating assembly includes a bearing seat 8 disposed on the top of the connecting ring 1, a rotating shaft 7 rotatably connected to the bearing seat 8, a U-shaped connecting frame 6 disposed on the rotating shaft 7, a micro motor 9 disposed on the bearing seat 8, the output shaft of the micro motor 9 being connected to the rotating shaft 7, the micro motor 9 being powered and controlled by existing technology, which can drive the rotating shaft 7 to rotate, causing the connecting frame 6 to rotate accordingly.

[0028] The drive assembly includes a fixed rod 10, on which a micro motor 11 is mounted. A bidirectional lead screw 12 is connected to the fixed rod 10 via bearings. The output shaft of the micro motor 11 is connected to the bidirectional lead screw 12. Slider blocks 13 are screwed onto both sides of the bidirectional lead screw 12. Slide grooves 14 are provided on both sides of the bottom of the fixed rod 10. The slide grooves 14 on both sides are slidably connected to the sliders 13 on both sides. The bottom of the sliders 13 on both sides is connected to the fixed blocks 5 on both sides. The micro motor 11 drives the bidirectional lead screw 12 to rotate, causing the sliders 13 on both sides to move under the guidance of the slide grooves 14.

[0029] The fixed rod 10 is connected to the connecting frame 6, so that the fixed rod 10 can be rotated by rotating the connecting frame 6.

[0030] Example 2

[0031] Reference Figures 1 to 3 To prevent ceramic powder from entering the fixed rod 10 through the slide groove 14 during engraving and affecting the rotation of the bidirectional lead screw 12, baffles 15 are provided on opposite sides of the sliders 13 on both sides. Sealing gaskets are provided at the bottom of the baffles 15 on both sides. The bottom of the sealing gaskets on both sides covers the slide grooves 14 on both sides, thereby improving the sealing effect. When the sliders 13 move, they can drive the baffles 15 and the sealing gaskets to move synchronously. Thus, after the fixed block 5 is adjusted to a new position, the slide grooves 14 are blocked by the sliders 13 and the sealing gaskets, respectively, preventing powder from entering the fixed rod 10 and protecting the bidirectional lead screw 12 to rotate stably.

[0032] The rest of the structure is the same as in Example 1.

[0033] Insert the fixing ring 3 with the ceramic disc 2 into the connecting ring 1, then rotate the connecting bracket 6 so that the fixing block 5 fits against the top of the fixing ring 3. Then, drive the fixing block 5 to move laterally through the slider 13 so that all the fixing blocks 5 on all sides abut against the inner ring of the convex ring 4. Thus, the fixing ring 3 and the convex ring 4 can be fixed at the same time, so that the ceramic disc 2 can be installed on the connecting ring 1. When disassembling, let the fixing block 5 leave the convex ring 4 first, and then rotate it 90 degrees to leave the fixing ring 3 to release the fixing of the ceramic disc 2.

[0034] The fixing rod 10 and fixing block 5 mentioned in the text are not located directly above the ceramic disc 2, and do not affect the engraving of the ceramic disc 2 by the engraving drill bit above.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
