Technical Field

[0001] The present invention relates to the technical field of engraving machines, in particular to an engraving machine tool with high stability. Background Art

[0002] From the processing principle, engraving is a combination of drilling and milling. The material is physically cut by rotating tools (such as milling cutters and carving knives). The milling engraving machine is a CNC equipment that physically cuts the material through a rotating milling cutter to achieve engraving, cutting, hollowing and other processing. It is a typical type of mechanical engraving machine.

[0003] A Chinese patent discloses a highly stable engraving machine tool, with publication number CN214873898U, comprising a bed and a support frame, wherein a support plate is fixedly mounted on the top of the bed, and anti-slip grooves are evenly distributed on the top of the support plate, an adjustment seat is fixedly mounted on the bottom of the support frame, and a first motor is fixedly mounted on one side of the support frame, a first threaded rod is rotatably mounted on the output end of the first motor, and a mounting seat is rotatably mounted on the first threaded rod, and a carving knife is fixedly mounted on the bottom of the mounting seat. This solution is provided with a first motor and a first threaded rod, and a second motor and a second threaded rod, which can be moved horizontally and vertically when the engraving machine is in use, thereby facilitating the engraving operation of the engraving machine and improving the practicality of the engraving machine, and a vacuum cleaner is provided in conjunction with a bellows and a suction nozzle, which can extract and absorb dust generated when the engraving machine is in use, thereby increasing the functionality of the engraving machine, making the engraving machine more convenient to use and expanding the scope of application.

[0004] However, there are still some disadvantages: the device uses a vacuum cleaner to suck the milling waste into the vacuum cleaner, but when cleaning the waste inside the vacuum cleaner, it is usually necessary to turn off the vacuum cleaner motor and stop the vacuuming, which affects the engraving efficiency. To this end, we have proposed a high-stability engraving machine tool to solve this problem. Summary of the Invention
