Automatic tool changing device of engraving machine and tool changing method of automatic tool changing device

Abstract

The invention discloses an automatic tool changing device of an engraving machine and a tool changing method of the automatic tool changing device. The automatic tool changing device comprises a six-axis mechanical arm and a tool magazine, wherein the six-axis mechanical arm is provided with a main shaft, and the tool magazine comprises a support, a plurality of tool stations capable of storing tools and at least one tool disassembling station capable of disassembling the tools on the main shaft; the tool stations and the tool disassembling station are all arranged on the support, and if no tool is arranged on the main shaft, the six-axis mechanical arm drives the main shaft to move to the corresponding tool station for tool installation; and if the tool is arranged on the main shaft, the six-axis mechanical arm drives the main shaft to move to the tool disassembling station for tool disassembling operation and then move to the corresponding tool station for tool installation. The automatic tool changing device has the advantages that through the combination of the six-axis mechanical arm and the tool magazine, automatic tool changing operation can be carried out, the tedious manual control link is omitted, and the automatic machining efficiency is improved.

Description

technical field [0001] The invention relates to an automatic tool changing device and a tool changing method of an engraving machine. Background technique [0002] As an art, stone carving is the perfect combination of stone and carving art, and has a long history. The development of stone carvings records the development of world civilization, shows exquisite folk skills, and is a kind of historical and cultural inheritance. In addition, stone carvings also have high economic value, and the value of processed stone carvings may be hundreds or even thousands of times higher than that of original stones. In recent years, with the improvement of living standards, more and more stone products are used in garden and architectural decoration industries. People's demand for stone carving products has increased unprecedentedly. The market's requirements for the type, shape and precision of special-shaped stone products are also increasing. Higher and higher. [0003] Stone carvi...

AI Technical Summary

Problems solved by technology

[0005] However, in the process of stone carving, the six-axis robotic arm needs to use different tools for different processing stages, and frequently replace the tools. The existing six-axis stone carving robot needs to manually take out the tool from the tool library, and then Adjust the six-axis robotic arm to a certain position and then manually switch the air valve for tool replacement. Failure to realize the linkage between the tool magazine and the six-axis robotic arm is not conducive to the automated production process
