Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, and more specifically to a numerical control machine tool with a dustproof structure. Background Art

[0002] CNC machine tool is the abbreviation of digital control machine tool. It is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, express them in coded numbers, input them into the CNC device through information carriers, and after calculation and processing, the CNC device sends out various control signals to control the movement of the machine tool and automatically process parts according to the shape and size required by the drawing.

[0003] The current CNC machining center with a dustproof structure, for example, the "A CNC machining center with a dustproof structure" proposed in patent application number CN202322018500.5, includes a machine tool body, a dustproof net fixedly installed on the side wall of the machine tool body, and guide components are provided on the side walls of the machine tool body on both sides of the dustproof net. A sliding frame is slidably arranged between the two sets of guide components, and a brush is provided on the sliding frame. The brush is fixedly connected to a brush head on the side of the brush close to the dustproof net, and the brush head contacts the surface of the dustproof net. A traction component is fixedly installed on the side wall of the machine tool body above the dustproof net; in the utility model, the traction component is used to drive the sliding frame to move upward in the vertical direction, and the sliding frame can descend under the action of gravity, so that the brush head of the brush contacts the dustproof net, so as to achieve the purpose of cleaning, avoid clogging of the dustproof net, and cause heat dissipation of the internal equipment of the machine tool body, and the dustproof net structure can effectively prevent metal waste from entering the interior of the machine tool body to avoid damage to the equipment.

[0004] Existing CNC machining centers with dustproof structures can clean the filter surface and prevent clogging by brushing the outer surface of the filter. However, in actual use, when the CNC machine tool processes parts, the metal scraps generated will splash inside the CNC machine tool and easily get clogged on the other side of the filter. It is not easy to clean the other end face of the filter or collect the scraps, which affects the use effect. Therefore, there is an urgent need to improve the technology of the CNC machining center with dustproof structure to improve this equipment. Utility Model Content

The cylindrical gear is meshed with the toothed disc to make the cylindrical gear itself rotate, and the rotation of the cylindrical gear can drive the electromagnetic rod to rotate, and the electromagnetic rod can generate a certain suction force on metal waste after being energized.
