Tool changing device for rotary denture engraving and milling machine

Abstract

The invention discloses a rotation type tool changer for a false tooth engraving and milling machine. The rotation type tool changer comprises a Z-axis feeding device, an X-axis feeding device and a rotary tool apron, wherein the Z-axis feeding device comprises a Z-axis motor, a Z-axis screw and a Z-axis support frame, the Z-axis screw is mounted on the Z-axis support frame, and is driven by the Z-axis motor, a mounting board is matched on the Z-axis screw by threads, a spindle motor and a spindle are mounted on the mounting board, one end of the spindle is connected with the spindle motor, a tool clamping base is mounted on the other end of the spindle, the X-axis feeding device comprises an X-axis motor, an X-axis support frame and an X-axis screw, the Z-axis support frame is matched on the X-axis screw by threads, the X-axis screw is mounted in the X-axis support frame, the X-axis motor drives the X-axis screw to rotate, the rotary tool apron is positioned on one side of the X-axis support frame, and the tool clamping base can move to be right above the rotary tool apron. The rotation type tool changer has the beneficial effect of being high in degree of automation, tool changing efficiency and tool changing accuracy.

Description

technical field [0001] The invention relates to a denture engraving device, in particular to a tool changing device for a rotary denture engraving and milling machine. Background technique [0002] Teeth are also called "tooth". Highly calcified tissue with a certain shape has the functions of chewing, helping pronunciation and maintaining facial shape. There are two sets of teeth in a person's life: deciduous teeth and permanent teeth. The permanent teeth are the second set of teeth of a person, with a total of 32. The deciduous teeth begin to fall off gradually from around the age of 6, and the permanent teeth begin to erupt to replace the deciduous teeth, and the permanent teeth are the last set of teeth of a person. It will lead to difficulty in chewing food and inaccurate pronunciation. When the teeth are damaged, the teeth need to be repaired in time, so dentures appear, and the existing denture processing is mainly divided into manual engraving and numerical control...

AI Technical Summary

Problems solved by technology

When the teeth are damaged, the teeth need to be repaired in time, so dentures appear, and the existing denture processing is mainly divided into manual engraving and numerical control engraving, while in numerical control engraving, the engraving knife needs to be replaced, usually manually. The efficiency of manual replacement is low, and after each replacement, it is necessary to re-set the knife, resulting in low efficiency of denture engraving
