Description

Technical Field

[0001] The present application relates to the field of denture processing equipment, and in particular to a plaster model positioning drilling device. Background Art

[0002] During the denture fabrication process, a model of the patient's teeth and periodontal tissue is typically obtained and then cast into a plaster model. This plaster model includes both the periodontal and dental models. However, since cast plaster models often have burrs and dimensional deviations, they require further polishing and correction to ensure accurate tooth dimensions.

[0003] In order to facilitate fine grinding of teeth, the tooth model is usually set to be movable so that the tooth model can be removed from the periodontal model. After the tooth model is polished, it needs to be reinstalled on the periodontal model. Therefore, in order to ensure the installation accuracy and position, it is necessary to install positioning posts on the tooth model in advance. Through these positioning posts, the tooth model can be accurately positioned and installed.

[0004] Currently, the positioning posts used are typically made of metal, and require mounting holes to be drilled into the bottom of the dental model to facilitate the alignment of the posts with the holes. However, drilling these holes poses challenges such as low positioning accuracy and prone to deviations in the drill position, severely impacting the quality and efficiency of denture fabrication.

[0031] The following is combined with Figure 1-2 This application is described in further detail.

[0032] The present embodiment discloses a gypsum model positioning and drilling device, comprising a base 1, a lifting platform 2 that can move up and down, a drill bit 3 and a locator 4. Specifically, a guide column 21 is provided on the lifting platform 2, and the guide column 21 is plugged into the guide hole on the base 1, so that the lifting platform 2 can move up and down stably. The drill bit 3 is fixed on the base 1, and the base 1 has a built-in drive motor to drive the drill bit 3 to rotate. A through hole is provided on the lifting platform 2, and when the lifting platform 2 descends, the drill bit 3 can pass through the through hole and extend above the lifting platform 2. The locator 4 is arranged above the lifting platform 2 through a support arm 11, and has an indicating component, which is located directly above the drill bit 3 and is used to accurately indicate the drilling position.

[0033] In this embodiment, the indicating component is specifically a laser pointer, which can emit a laser point to accurately indicate the drilling position, and the drilling position is directly below the position of the laser point, so that the staff can easily judge the accuracy of the drilling.

[0034] To use the system, first place the plaster model on the lifting platform 2 and use the laser pointer to determine the drilling location. Then, activate the drill bit 3, lowering the lifting platform 2 so that the drill bit 3 can drill the plaster model. The laser pointer continuously indicates the drilling location to ensure accurate drilling. Once drilling is complete, the lifting platform 2 rises, allowing the drill bit 3 to be removed from the hole and the plaster model to be removed.

[0035] In this embodiment, the indicating component uses a telescopic rod instead of a laser pointer. The telescopic rod is set vertically and accurately indicates the drilling position through physical contact.

[0036] Furthermore, the lifting platform 2 has an annular groove 22 formed around the through hole. This groove collects dust generated during the drilling process, maintaining a clean working environment. Furthermore, the base 1 has a dust collection hole 23 formed within the annular groove 22 and extending to the bottom of the lifting platform 2.

[0037] In this embodiment, the gypsum model positioning and drilling device also includes a vacuum cleaner, which is connected to the dust collection hole 23 via a pipe. During the drilling process, the vacuum cleaner can suck away dust collected in the annular groove 22, maintaining a clean working environment. Furthermore, the presence of the vacuum cleaner reduces the operator's exposure to dust, protecting their health.

[0038] When in use, the vacuum cleaner is started to suck away the dust in the annular groove 22 through the pipe. The suction force of the vacuum cleaner can be adjusted as needed to adapt to different working environments and requirements. The use of the vacuum cleaner not only keeps the working environment clean, but also improves work efficiency and product quality.

[0039] An elastic support member 24 is provided on the base 1, and the lifting platform 2 is connected to the base 1 via the elastic support member 24. The elastic support member 24 can be an elastic element such as a spring, and the lifting platform 2 can be operated to descend by manually pressing it, and can also be automatically raised.

[0040] This application further incorporates a height-limiting rod 12. This rod 12 is vertically mounted on the base 1 and threaded thereto. A limiter is provided on the rod 12, which abuts against the top of the lift platform 2, ensuring that the lift platform 2 can move up and down within a predetermined range. This design enhances the safety and stability of the device.

[0041] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
