Description

Technical Field

[0001] The utility model relates to the technical field of machine tool processing, in particular to a fixing fixture for an engraving machine. Background Art

[0002] First of all, from the processing principle, the engraving machine is a combination of drilling and milling. The engraving machine has a variety of data input modes according to the needs. Computer engraving machines are divided into laser engraving and mechanical engraving. Both types are divided into high-power and low-power. Because the application range of engraving machines is very wide, it is necessary to understand the most suitable application range of various engraving machines.

[0003] With the development of the times, many machines have replaced the original handicrafts, reducing the tediousness and working hours of manual labor and improving the production efficiency of products. The most common one is the engraving industry. The original manual engraving is not fine enough, and the working hours are long and the labor cost is very expensive. However, although the existing engraving machines have replaced manual engraving and improved production efficiency, due to the different volumes and gravity of the engravings, manual work is required to fix the engravings when fixing them, which is time-consuming and labor-intensive. At the same time, the existing engraving machines usually fix the engravings on a platform. When the engravings need to be rotated for engraving, manpower is required to flip the engravings and re-carve them, and the flipping and fixing process is time-consuming and labor-intensive.
