[0002] As people's material and spiritual living standards continue to improve, people have higher and higher requirements for stone decoration effects. In addition to simple stone slab flat surface decoration, there is also an increasing demand for exquisite three-dimensional carved stone products. Stone engraving machines are widely favored by stone processing plants as equipment that can replace manual automated production, and the demand for stone engraving machines in the industry is also increasing.

[0003] At present, in the process of stone carving, the loading and unloading of stone is mostly done manually, which is time-consuming, labor-intensive and labor-intensive. The table of the machine tool is equipped with auxiliary T-slots. The stone is fixed by a pressure plate fixed in the T-slot and pressed against the stone. Because it is pressed against the stone, the four directions of the stone need to be pressed against the pressure plate to prevent it from moving. Because the pressure plate is tightened manually, the workers have to operate it for a long time, the labor cost is high, the fixing of the stone is not uniform, and improper operation will cause waste of stone. In the process of stone carving, the starting point is found by manually operating the machine tool to find the coordinate point, which has low precision and takes a long time, resulting in labor waste.
