Technical Field

[0001] The utility model relates to the technical field of numerically controlled machine tools, in particular to an oil mist liquefaction circulation component and a numerically controlled machine tool. Background Art

[0002] During the machining process of machine tools, especially CNC machine tools, a large amount of oil mist will be generated. Generally, an exhaust hole is set on the machine tool, and a filter element is set on the exhaust hole. The generated oil mist is filtered and discharged outside the machine tool through the filter element.

[0003] However, to discharge oil mist in this way, the filter element needs to be replaced frequently, and the filtration part must not be thorough, or the filter element is not replaced for a long time, the oil mist will be discharged outside the machine tool. Since general processing is done indoors, the oil mist cannot be discharged from the room in time, which can easily cause the wall to be contaminated and yellow over time, making it difficult to clean and even affecting the health of the staff. In addition, the oil mist discharged from the machine tool cannot be recycled, which is not environmentally friendly and increases costs.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an oil mist liquefaction circulation component and a CNC machine tool are proposed. Utility Model Content

[0009] Furthermore, the casing is connected to the liquefaction component through a connecting pipe, and the liquefaction component includes an outer tube, a cooling circulation pump and an inlet and outlet liquid pipe. The cooling circulation pump is fixed to the outer wall of the outer tube, and the cooling circulation pump is connected to the inner cavity of the outer tube through the inlet and outlet liquid pipe.

[0010] Furthermore, the liquefaction assembly also includes an air inlet chamber and a connecting flange. The air inlet chamber is fixed to the top of the outer cylinder, and the air inlet chamber is connected to the end of the connecting pipe away from the casing through the connecting flange.

The liquefaction component 2 includes an outer cylinder 201, a cooling circulation pump 202 and an inlet and outlet liquid pipe 203.
