Description

Technical Field

[0001] This utility model relates to the field of dental prosthesis processing technology, and in particular to a clamp for dental prosthesis carving. Background Technology

[0002] Dentures, commonly known as "false teeth," are similar to how "prosthetic legs" or "prosthetic limbs" are called "prosthetics." The term "denture" refers to teeth that fulfill their "duty" for humans. Dentures are divided into two types: removable and fixed. Fixed dentures (commonly known as "fixed false teeth") cannot be removed by the patient, while removable dentures (commonly known as "removable dentures") can be easily removed and worn by the patient. Removable dentures are suitable for cases where most teeth are missing and few teeth remain. Fixed dentures utilize the healthy teeth on either side of the missing teeth for support, fixing the denture in the mouth. They are suitable for cases where a few teeth are missing, intermittent edentulism occurs, and the remaining teeth are in good health. During the manufacturing process, clamps are used to hold the workpiece in place during carving.

[0003] A search revealed a Chinese patent (authorization announcement number CN219113885U) disclosing a fixture for dental prosthesis carving. The fixture includes a base with a docking groove in the middle. A positioning sleeve is fixedly installed within the groove. A clamping mechanism is fixedly installed at the upper end of the positioning sleeve. The clamping mechanism includes a mounting bracket, a mounting base, a first clamping frame, a movable slide, a second clamping frame, and an adjusting screw. An exhaust mechanism is fixedly installed at the bottom of the positioning sleeve. This exhaust mechanism includes a drive motor, a docking bracket, fan blades, a docking base, and an exhaust duct. The docking base is fixedly installed at the bottom of the positioning sleeve. This patented technology allows the second clamping frame to move inwards after rotating the adjusting screw, thus clamping the workpiece. Simultaneously, the drive motor can be activated during carving, causing the fan blades to rotate at high speed. This high-speed rotation creates a negative pressure at the bottom of the positioning sleeve, adsorbing dust generated during carving and preventing dust from scattering.

[0004] However, the above-mentioned device still has some drawbacks in actual use. The most obvious one is that in the process of denture processing, the denture is clamped by a clamp, and the processing of the second denture can only be carried out after the first denture is processed and disassembled. This not only increases the working time of clamping and disassembling the denture, but also makes it impossible to process multiple dentures at the same time, resulting in slow carving efficiency. Utility Model Content

[0005] In view of the above-mentioned problems existing in the prior art, the main purpose of this utility model is to provide a clamp for dental prosthesis processing and carving.

[0006] The technical solution of this utility model is as follows: a fixture for dental prosthesis processing and carving includes a base, with brackets fixedly connected to both ends of the top of the base, a square strip rotatably installed between the two brackets, and square frames fixedly connected at equal intervals to the outer side of the square strip. Fixture bodies are fixedly connected at equal intervals to the side of the square frames away from the square strip, and a limiting groove is formed inside the fixture body. Fixed blocks are slidably connected to both ends of the limiting groove, and clamping members are fixedly connected to the top of the fixed blocks. A pushing block is provided inside the fixture body and between the two fixed blocks.

[0007] By adopting the above technical solution, the purpose of clamping dentures of different sizes can be achieved by pushing the block down and using a high-strength spring. During the processing of a row of dentures, dentures that have not yet been loaded can be clamped and loaded, while dentures that have been processed can be disassembled and unloaded. This reduces the working time for clamping and disassembling dentures and allows for the simultaneous carving of multiple dentures.

[0008] In a preferred embodiment, the top of the base is provided with an adjustment assembly, which includes a servo motor fixedly mounted on one side of one of the brackets. The output shaft of the servo motor is fixedly connected to a drive gear, and a driven gear is rotatably mounted on the outer side of one of the brackets. The driven gear meshes with the drive gear.

[0009] By adopting the above technical solution, the rotation of the servo motor can drive the drive gear to rotate, which in turn drives the driven gear to rotate, thereby adjusting the direction of the square bar.

[0010] In a preferred embodiment, the rotation shaft of the driven gear passes through the bracket and is fixedly connected to the central axis of the square bar, and the clamping members are all slidably connected to the top end of the clamp body.

[0011] By adopting the above technical solution, the rotation of the driven gear can drive the square bar to rotate.

[0012] In a preferred embodiment, the fixture body is provided with a limiting component inside. The limiting component includes a fixing groove formed inside the fixture body and located on both sides of the limiting groove. A limiting rod is fixedly connected inside each fixing groove. A slider is slidably connected to the outside of each limiting rod. A high-strength spring is sleeved on the outside of each limiting rod and on the side of the slider.

[0013] By adopting the above technical solution, the combined use of the slider and the limiting rod can limit the movement of the fixed block and make the fixed block more stable during the movement.

[0014] In a preferred embodiment, the two sliders are respectively fixedly connected to both sides of the fixed block, and electric telescopic rods are fixedly installed at equal intervals on the inner wall of the frame. The piston rod of the electric telescopic rod passes through the inside of the frame and is fixedly connected to the corresponding push block.

[0015] By adopting the above technical solution, the piston rod of the electric telescopic rod can be extended and retracted to drive the push block to move up and down.

[0016] In a preferred embodiment, both the fixed block and the pushing block have mutually cooperating inclined surfaces on their adjacent sides.

[0017] By adopting the above technical solution and setting the inclined surface, the fixed block and the pushing block can fit more tightly.

[0018] In one preferred embodiment, a controller is fixedly mounted on the outer side of one of the brackets, and a rubber layer is fixedly connected to the adjacent sides of both clamping members.

[0019] By adopting the above technical solution and adding a rubber layer, the stability of denture clamping can be improved.

[0020] In a preferred embodiment, both the servo motor and the electric telescopic rod are electrically connected to the controller.

[0021] By adopting the above technical solution, the servo motor and electric telescopic pole can be started and stopped by the controller.

[0022] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0023] 1. In this utility model, when it is necessary to process dentures, by pushing the block upward, the two fixed blocks above it can be pushed open, which in turn will cause the two clamping parts to open, so as to facilitate the placement of dentures between the two clamping parts. Then, by pushing the block downward, and using the high-strength spring, dentures of different sizes can be clamped. During the processing of a row of dentures, dentures that have not been loaded can be clamped and loaded, and dentures that have been processed can be disassembled and unloaded, thereby reducing the working time of clamping and disassembling dentures, and multiple dentures can be carved at the same time, thereby improving work efficiency.

[0024] 2. In this utility model, when the first row of dentures is completed and the second row of dentures needs to be processed, the rotation of the servo motor can drive the drive gear to rotate, which in turn drives the driven gear to rotate, thereby adjusting the direction of the square strips to speed up the overall processing efficiency of the dentures.

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0031] Reference Figure 1-4 A dental prosthesis carving jig includes a base 1, with brackets 2 fixedly connected to both ends of the top of the base 1. A square strip 3 is rotatably mounted between the two brackets 2. Square frames 4 are fixedly connected at equal intervals to the outer sides of the square strip 3. A jig body 9 is fixedly connected at equal intervals to the side of the square frame 4 away from the square strip 3. A limiting groove 11 is formed inside each jig body 9. A fixing block 12 is slidably connected to both ends of the limiting groove 11. A clamping member 10 is fixedly connected to the top of each fixing block 12. A pushing block 13 is provided inside the jig body 9 and between the two fixing blocks 12. When it is necessary to carve the dental prosthesis... During processing, by pushing block 13 upward, the two fixed blocks 12 above it can be pushed open, which in turn will cause the two clamping parts 10 to open, so that the denture can be placed between the two clamping parts 10. Then, by pushing block 13 downward, the high-strength spring 18 can be used to clamp dentures of different sizes. During the processing of a row of dentures, unloaded dentures can be clamped and loaded, and processed dentures can be disassembled and unloaded, thereby reducing the working time of clamping and disassembling dentures, and multiple dentures can be carved at the same time, thereby improving work efficiency.

[0032] Reference Figure 2 The top of the base 1 is equipped with an adjustment component, which includes a servo motor 7 fixedly installed on one side of one of the brackets 2. The output shaft of the servo motor 7 is fixedly connected to a drive gear 8. A driven gear 6 is rotatably installed on the outer side of one of the brackets 2. The driven gear 6 meshes with the drive gear 8. When the first row of dentures is completed and the second row of dentures needs to be processed, the rotation of the servo motor 7 can drive the drive gear 8 to rotate, thereby driving the driven gear 6 to rotate, and thus adjusting the direction of the square bar 3 to speed up the overall processing efficiency of the dentures.

[0033] Reference Figure 3 The rotating shaft of the driven gear 6 passes through the bracket 2 and is fixedly connected to the central axis of the square bar 3. The clamping parts 10 are all slidably connected to the top of the clamp body 9. The rotation of the driven gear 6 can drive the square bar 3 to rotate.

[0034] Reference Figure 4 The clamp body 9 is equipped with a limiting component inside. The limiting component includes a fixing groove 15 on both sides of the limiting groove 11 inside the clamp body 9. A limiting rod 17 is fixedly connected inside the fixing groove 15. A slider 16 is slidably connected to the outside of the limiting rod 17. A high-strength spring 18 is sleeved on the outside of the limiting rod 17 and on one side of the slider 16. Through the cooperation of the slider 16 and the limiting rod 17, the movement of the fixing block 12 can be limited to a certain extent. At the same time, the fixing block 12 can be made more stable during the movement. The use of the high-strength spring 18 can push the two clamping parts 10 for clamping by its elastic force.

[0035] Reference Figure 3 Two sliders 16 are fixedly connected to the two sides of the fixed block 12 respectively. Electric telescopic rods 14 are fixedly installed at equal intervals on the inner wall of the frame 4. The piston rod of the electric telescopic rod 14 passes through the inside of the frame 4 and is fixedly connected to the corresponding push block 13. By extending and retracting the piston rod of the electric telescopic rod 14, the push block 13 can be driven to move up and down, thereby achieving the purpose of clamping and releasing the denture.

[0036] Reference Figure 3 Both the fixed block 12 and the pushing block 13 have mutually cooperating inclined surfaces on their adjacent sides. The inclined surfaces make the fixed block 12 and the pushing block 13 fit more tightly.

[0037] Reference Figure 3 One of the brackets 2 has a controller 5 fixedly installed on its outer side, and the two clamping parts 10 are fixedly connected to a rubber layer on their adjacent sides. The rubber layer can improve the stability of the denture clamping.

[0038] Reference Figure 1 The servo motor 7 and the electric telescopic rod 14 are both electrically connected to the controller 5, and the controller 5 can control the servo motor 7 and the electric telescopic rod 14 to start and stop.

[0039] Working principle: First, when it is necessary to process the denture, the electric telescopic rod 14 in one of the boxes 4 can be activated by the controller 5. The piston rod of the electric telescopic rod 14 extends, which can drive the push block 13 to move upward, thereby pushing the two fixed blocks 12 above it to unfold, which in turn will drive the two clamping parts 10 to open, so as to facilitate the placement of the denture between the two clamping parts 10. Then, the push block 13 is controlled to move downward, and the high-strength spring 18 can be used to achieve the purpose of clamping dentures of different sizes.

[0040] Then, the first row of dentures is carved. During the processing of the first row of dentures, the unloaded dentures can be clamped and loaded, and the finished dentures can be disassembled and unloaded. This reduces the working time of clamping and disassembling dentures, and allows multiple dentures to be carved at the same time, thereby improving work efficiency.

[0041] The combined use of slider 16 and limit rod 17 can limit the movement of fixed block 12, making fixed block 12 more stable during movement. The inclined surface design also makes fixed block 12 fit more tightly with push block 13.
