Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to an anti-blocking type wastewater circulation filtering device for numerical control machine tools. Background Art

[0002] CNC machine tools are short for digitally controlled machine tools. They are automated machine tools equipped with a program control system that can operate and process parts according to a pre-programmed program. When CNC machine tools are performing high-gloss processing, the friction between the workpiece and the tool will generate a lot of heat. In order to avoid the heat causing deformation of the workpiece and affecting the accuracy and processing efficiency, cutting fluid circulation is required to cool and lubricate the workpiece and the tool.

[0003] In the existing CNC machine tool filtering device, the cutting tools on the CNC machine tools will generate high temperatures during long-term processing, so cutting fluid is needed to cool the cutting tools. The debris generated by the cutting tools during processing and the cutting fluid fall on the workbench and mix with each other. If they are not separated, the cutting fluid can easily become unusable.

[0004] In the patent document with publication number CN216461783U3, a filtering device for cutting fluid of a CNC machine tool and the CNC machine tool thereof are disclosed. The cutting fluid in the container box is discharged to the milling cutter below through the mouth of the front end of the telescopic tube. Two brushes will move the debris on the slide plate to the opposite direction. At this time, all the debris will slide onto the filter net, and the used cutting fluid will leak from the filter net into the collection box below. At this time, the debris and the cutting fluid will be separated by the filter net, and the cutting fluid can be used again after being filtered, which not only saves the money for buying cutting fluid but also concentrates the debris and is convenient for cleaning.

[0005] However, the cutting fluid filtering device of the CNC machine tool and the CNC machine tool thereof adopt direct filtration, which has a slow filtration speed and only uses one filtration, which may lead to problems such as reduced work efficiency and poor filtration effect. Therefore, it is necessary to propose a CNC machine tool anti-blocking wastewater circulation filtration equipment. Utility Model Content

The working waste water of the CNC machine tool in the filter box 102 will be thrown out from the inside of the filter box 102 under the action of the centrifugal force generated after the rotation of the filter box 102, thereby entering the filter box 101 and completing the preliminary filtration.
