Engraving machine capable of achieving stable clamping of different thicknesses and detecting parallelism

The invention discloses an engraving machine capable of achieving stable clamping of different thicknesses and detecting parallelism. The engraving machine comprises an engraving machine body, whereina working cavity penetrating front and back is formed inside the engraving machine body, a first function box capable of freely moving through numerical control is arranged on the upper wall inside the working cavity, an engraving tool used for engraving is clamped at the lower end of the first function box, and a second function box is fixedly connected to the lower side of the excircle end faceof the first function box. According to the engraving machine, stable clamping is carried out by adapting to the thickness of engraving plates, and parallelism detection of the engraving plates is carried out before work is started, so that the engraving precision of the machine is higher, the effect of blowing first and then sucking is carried out in the engraving process of the machine, and engraving chippings are compl
