Description

Technical Field

[0001] This utility model relates to the technical field of dental prosthesis processing equipment, specifically a rotary dental prosthesis milling machine tool changing device. Background Technology

[0002] Dental prosthesis milling refers to the technology of precision machining of dental restorations (such as dentures, crowns, and bridges) using computer numerical control (CNC) milling machines. It is a core part of digital oral restoration. The material is shaped by cutting with a high-speed rotating cutting tool (such as a diamond end mill), which is a subtractive manufacturing technology.

[0003] The "Automatic Tool Changer for a Denture Milling Machine" disclosed in application number "202420259685.0" "includes a top plate, a clamping tool holder, and a tool. The clamping tool holder is installed on the lower surface of the top plate. A tool changing mechanism for driving multiple sets of tools to be installed is installed on the lower surface of the top plate. A disassembly mechanism is provided on the side of the tool changing mechanism near the clamping tool holder. A limit mechanism is installed inside the disassembly mechanism. By activating the tool changing mechanism, the tool that is compatible with the clamping tool holder moves and engages with the tool inside the clamping tool holder. This allows the device to replace manual tool handling and install the tool inside the clamping tool holder, thereby shortening the time spent on tool replacement and improving the production efficiency of the device."

[0004] However, the above method still has the following drawbacks: the tool changing mechanism and the disassembly mechanism can change the tool, but the electric telescopic rod and slider of the tool changing mechanism need to be set horizontally, which takes up a lot of installation space. After the disassembly mechanism disassembles the tool, it is not convenient to put the disassembled tool into the storage box, making it difficult to repeat the tool changing activity.

This enables rotary tool changing, has a compact structure, does not occupy space, and can repeatedly perform tool changing activities.

[0026] In this embodiment, preferably, the rotary drive mechanism 5 includes an electromagnetic brake motor 501.

After the housing 7 rotates, the cooperation between the worm 502 and the worm wheel 503 and the electromagnetic braking of the electromagnetic brake motor 501 can achieve double self-locking of the horizontal support shaft 4, which is safe and reliable.

[0027] In this embodiment, preferably, the tool clamping mechanism 9 includes a servo motor 901, which is fixedly connected to the surface of the mounting base 10. The output shaft of the servo motor 901 is fixedly connected to a rotating shaft 903 via a coupling 902. One end of the rotating shaft 903 is fixedly provided with a chuck 904 for fixing the tool.

[0030] In use, firstly, the mounting plate 1 is fixed to the frame of the dental prosthesis milling machine through the mounting holes. The mounting plate 1 can provide support for the housing 7 through the horizontal support shaft 4. Then, the milling tool is clamped by the tool clamping mechanism 9. Then, the sliding support 3 is lifted by the hydraulic cylinder 2, causing the housing 7 to rise.
