Technical Field
[0001] This utility model relates to the field of auxiliary device technology, and in particular to an auxiliary device for denture manufacturing based on 3D printing. Background Technology
[0002] Dentures are what people commonly call false teeth. Just like prosthetic legs and limbs are called prosthetics, dentures refer to teeth that fulfill human needs. In medicine, they are a general term for restorations made after partial or complete loss of upper and lower jaw teeth. Dentures are divided into two types: removable and fixed. Fixed dentures cannot be removed by the patient, while removable dentures can be easily removed by the patient.
[0003] While traditional dental prosthesis manufacturing auxiliary devices have solved the problems of low efficiency and difficulty in preliminary shaping of manual grinding, they have obvious shortcomings. They cannot flexibly adapt to workpieces of different heights, require frequent changes of fixtures or adjustments to the entire device, are cumbersome to operate, and mostly operate on a single grinding component, making it difficult to process different positions of the workpiece at the same time, resulting in low efficiency and poor grinding uniformity. Utility Model Content
[0004] The purpose of this utility model is to provide a dental prosthesis manufacturing auxiliary device based on 3D printing. Through the cooperation of the lifting electric telescopic cylinder and the lifting electric telescopic rod, the connecting frame and the grinding component can be adjusted up and down to adapt to the grinding needs of workpieces of different heights. The limiting slide rod can stabilize the lifting trajectory of the connecting frame and avoid grinding sway. The grinding motor drives the grinding rotating roller and grinding pulley to rotate through the grinding rotating column. With the cooperation of symmetrical grinding pulleys, different positions of the workpiece can be processed at the same time, improving grinding efficiency and uniformity.
[0005] To achieve the above objectives, a 3D-printed dental prosthesis manufacturing auxiliary device is provided, comprising: a work platform and a clamping assembly. A mounting frame is fixedly connected to the upper surface of the work platform. Lifting electric telescopic cylinders are fixedly connected to both the left and right sides of the upper surface of the mounting frame.

The work platform and mounting frame provide stable support, the lifting system allows for flexible height adjustment, the limiting slide rods ensure stability, and the dual grinding motors drive symmetrical pulleys, enabling simultaneous processing of multiple positions, thus improving efficiency and uniformity.
[0006] According to the aforementioned 3D-printed dental prosthesis manufacturing auxiliary device, the lifting electric telescopic cylinder extends to the inner surface of the mounting frame, and the lifting electric telescopic rod is located on two limiting slide rods. The concealed design of the lifting cylinder reduces external interference, and the double limiting slide rods clamp the telescopic rod from the left and right, making the lifting and lowering more stable and improving the stability and safety of the polishing process.
[0007] According to the aforementioned 3D-printed dental prosthesis manufacturing auxiliary device, the limiting slide rod extends to the upper surface of the mounting frame, and the number of the limiting slide rods corresponds to the number of clamping electric telescopic cylinders.

The number of slide rods corresponds to the number of clamping cylinders, ensuring symmetrical force distribution and improving the overall structural coordination and operational reliability.
[0008] According to the aforementioned 3D-printed dental prosthesis manufacturing auxiliary device, the grinding rotating column extends to the inner surface of the connecting frame, and the grinding rotating rollers are symmetrically arranged on the front and rear sides of the inner surface of the connecting frame. The built-in rotating column has high transmission efficiency, and the symmetrical roller layout ensures uniform force on the grinding belt, reduces vibration, improves processing consistency, and extends the service life of the equipment.
[0009] According to the aforementioned 3D-printed dental prosthesis manufacturing auxiliary device, the grinding pulleys are symmetrically arranged between two grinding rotating rollers. The symmetrical pulleys simultaneously contact both sides of the workpiece, allowing for simultaneous grinding of different positions, shortening processing time, and improving surface treatment uniformity and finished product quality.
[0010] According to the aforementioned 3D-printed denture manufacturing auxiliary device, the clamping assembly is located on the inner surface of the mounting frame. An adjusting motor and a clamping electric telescopic cylinder are fixedly connected to the left and right sides of the inner surface of the mounting frame, respectively.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.
[0024] Reference Figure 1-4 This utility model discloses a 3D-printed dental prosthesis manufacturing auxiliary device, comprising: a working platform 1 and a clamping assembly. A mounting frame 3 is fixedly connected to the upper surface of the working platform 1, providing stable support for the entire device. The mounting frame 3 serves as the mounting base for various functional components, enabling the subsequent lifting, grinding, and clamping mechanisms to work collaboratively. Lifting electric telescopic cylinders 10 are fixedly connected to both the left and right sides of the upper surface of the mounting frame 3. The lifting electric telescopic cylinders 10 provide driving force for the lifting system, and their telescopic movements drive the entire grinding mechanism up and down, adjusting the grinding position. A lifting electric telescopic rod 11 is fixedly connected to the output end of the lifting electric telescopic cylinder 10, transmitting the power of the lifting electric telescopic cylinder 10 to a connecting frame 13, enabling the grinding assembly to rise and fall precisely and smoothly. A connecting frame 13 is fixedly connected to the lower surface of the lifting electric telescopic rod 11, serving as the mounting carrier for the grinding motor 14 and the grinding rotating column 15, converting the lifting power into the overall displacement of the grinding mechanism. The upper surface of the connecting frame 13 has two... Limiting slide rods 12 are fixedly connected to both sides of the connecting frame 13, passing through the mounting frame 3. These limiting slide rods 12 provide guidance and stability for the lifting and lowering of the connecting frame 13, preventing swaying during grinding. Grinding motors 14 are fixedly connected to both the front and rear sides of the side wall of the connecting frame 13. The grinding motors 14 provide the power source for the grinding system, driving the grinding rotating column 15 to rotate the grinding rotating roller 16 and grinding pulley 17. The output end of the grinding motor 14 is fixedly connected to the grinding rotating column 15, which transmits the rotational motion of the grinding motor 14 to the grinding roller 16. The grinding roller 16 is equipped with a pressure sensor inside, which enables the grinding pulley 17 to obtain the required speed and torque. The grinding roller 16 is fixedly connected to the outer surface of the grinding rotating column 15. The grinding roller 16 serves as a support structure for the grinding pulley 17, ensuring that the grinding belt maintains appropriate tension and position during operation. The grinding pulley 17 is rolledly connected to the outer surface of the grinding roller 16. The grinding pulley 17 directly contacts the surface of the denture, and the grinding process of the denture is achieved through its rolling, thus completing the required surface treatment.
[0025] The lifting electric telescopic cylinder 10 extends to the inner surface of the mounting frame 3. This structural design allows the lifting system to directly act on the grinding mechanism inside the mounting frame 3, reducing the power transmission path and improving the response speed. The lifting electric telescopic rod 11 is located on two limiting slide rods 12, which are symmetrically distributed on both sides of the lifting electric telescopic rod 11, forming a stable triangular support structure to ensure smooth and reliable lifting. The limiting slide rods 12 extend to the upper surface of the mounting frame 3. This arrangement of the limiting slide rods 12 increases the guide stroke and improves the stability of the connecting frame 13 during large-range lifting. The number of limiting slide rods 12 corresponds to the number of clamping electric telescopic cylinders 7. This correspondence ensures the matching of the grinding mechanism and the clamping mechanism in terms of quantity and position. To facilitate the uniform application of grinding force, the grinding rotating column 15 extends to the inner surface of the connecting frame 13. This design allows the grinding rotating column 15 to directly drive the grinding rotating roller 16 located inside the connecting frame 13, reducing transmission losses. The grinding rotating rollers 16 are symmetrically arranged on the front and rear sides of the inner surface of the connecting frame 13. The symmetrical arrangement of the grinding rotating rollers 16 ensures that the grinding pulley 17 is subjected to uniform force, improving the stability and consistency of the grinding process. The grinding pulley 17 is symmetrically arranged between the two grinding rotating rollers 16. This layout allows the grinding belt to evenly contact the denture surface, achieving a comprehensive and thorough grinding effect. The clamping assembly is located on the inner surface of the mounting frame 3. The clamping assembly is installed inside the mounting frame 3 and maintains an appropriate distance from the grinding mechanism to facilitate stability during the grinding process. The mounting bracket 3 has an adjusting motor 4 and a clamping electric telescopic cylinder 7 fixedly connected to its left and right sides on the inner surface of the denture. The adjusting motor 4 and the clamping electric telescopic cylinder 7 apply clamping force to the denture from both sides, forming a stable clamping system. The output end of the adjusting motor 4 is fixedly connected to an adjusting rotating column 5, which transmits the power of the adjusting motor 4 to the clamping abutment block 6, realizing fine adjustment of the denture position. One end of the adjusting rotating column 5 is fixedly connected to the clamping abutment block 6, which directly contacts the denture. The precise positioning of the denture is achieved by driving the adjusting motor 4. The output end of the clamping electric telescopic cylinder 7 is fixedly connected to a clamping electric telescopic rod 8, which transmits the power of the clamping electric telescopic cylinder 7 to the abutment rotating seat 9, realizing clamping. The force adjustment is achieved by fixing a contact rotating seat 9 to one end of the clamping electric telescopic rod 8. The contact rotating seat 9 cooperates with the clamping contact block 6 to clamp the denture from the other side, forming a stable clamping structure. The positions of the contact rotating seat 9 and the clamping contact block 6 are parallel, which ensures that the clamping force is evenly distributed on both sides of the denture, avoiding damage to the denture during clamping. The connecting frame 13 is located between the adjusting motor 4 and the clamping electric telescopic cylinder 7. This positional relationship allows the grinding mechanism to accurately align with the clamped denture, ensuring accurate grinding position. The upper surface of the work platform 1 is symmetrically connected to the controller 2. The controller 2 serves as the control core of the entire device, receiving input signals and controlling the coordinated operation of each actuator. The controller 2 is located in front of the mounting frame 3.Front-mounted installation facilitates monitoring and operation by personnel, while avoiding interference with other components and improving operational convenience.
[0026] Working Principle: First, place the entire device on a stable working surface to ensure the stability of the working platform 1. Use controller 2 to check the proper connection and power supply of each motor, sensor, and telescopic cylinder. Place the denture blank in the clamping position within the mounting frame 3, ensuring one end is close to the clamping contact block 6 and the other end is aligned with the contact rotating seat 9. Secure the clamping by activating the electric telescopic cylinder 7 via controller 2, which drives the electric telescopic rod 8 to extend forward, ensuring close contact between the contact rotating seat 9 and the side of the blank. Simultaneously, adjust motor 4 to drive the adjusting rotating column 5, which in turn finely adjusts the position of the clamping contact block 6, clamping the blank from the other side to ensure a firm and even clamping. Adjust the grinding mechanism position by activating the lifting electric telescopic cylinder 10 via controller 2, which drives the lifting electric telescopic rod 11 to move the connecting frame 13 up and down along the limiting slide rod 12, bringing the grinding pulley 17 close to the grinding area on the blank surface. The grinding operation begins with the grinding motor 14 activated. Power is transmitted to the grinding roller 16 via the grinding rotating column 15. The pressure sensor inside the grinding roller 16 facilitates grinding control of the denture workpiece, causing the grinding pulley 17, which is fitted between the two rollers, to rotate at high speed and grind the surface of the workpiece. During the grinding process, the controller 2 can adjust the extension and retraction of the lifting electric telescopic cylinder 10 in real time to change the grinding position. The motor 4 can also be controlled to fine-tune the angle of the workpiece to meet the grinding requirements of different curved surfaces. After the grinding is completed and unloaded, the grinding motor 14 is turned off, and the lifting electric telescopic cylinder 10 is operated to raise the grinding mechanism back to its initial position. Then, the controller 2 controls the clamping electric telescopic cylinder 7 to retract, releasing the contact rotating seat 9, and removing the finished denture. The grinding debris on the grinding pulley 17 is cleaned and maintained, and all connections are checked for looseness to ensure that the device is in good condition before the next use.
