Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a laser safety protection device for numerical control machine tools. Background Art

[0002] With the continuous development of the manufacturing industry, CNC machine tools are increasingly used in industrial production. CNC machine tools offer advantages such as high precision, high efficiency, and a high degree of automation, making them capable of meeting the processing needs of complex parts. However, CNC machine tools also pose certain safety risks during processing, especially those posed by laser processing. Lasers have high energy, high brightness, and high directivity. Without effective safety protection devices, laser processing on CNC machine tools can cause serious harm to operators and equipment. For example, lasers can cause burns to the eyes and skin, and can even cause safety accidents such as fires. Lasers can also damage key components of CNC machine tools, such as optical elements and sensors, affecting their normal operation.

[0003] For example, announcement number CN221289909U discloses a laser cutting machine with a protective structure, which relates to the field of laser cutting technology and includes a base machine tool. The lower end outer surface of the base machine tool is provided with a plurality of groups of fixedly connected base pillars, the right outer surface of the base machine tool is provided with a base electrical box door rotatably connected to the base machine tool, the upper end outer surface of the base machine tool is provided with a protective connecting plate fixedly connected to the base machine tool, the front end outer surface of the protective connecting plate is provided with a detachably connected controller, the front end outer surface of the controller is embedded with a detachably connected CNC panel, and the right side of the CNC panel is provided with a plurality of control buttons. The utility model discloses a laser cutting machine tool with a protective structure. The protective shell provided therein effectively blocks the reflected light formed by lens reflection and diffuse reflection, thereby preventing the laser from causing damage to the human body, especially the cornea and retina of the eye, causing damage to skin tissue, and resulting in a decline in overall function, thereby ensuring the labor safety of the staff. However, during use, due to the need for protection, it is impossible to observe the laser for operation, resulting in a certain deviation and inability to make timely adjustments. Moreover, when the laser is used to cut objects, gas and dust are generated, which not only have an unpleasant smell but also cause certain physical and mental health problems to the operator. Therefore, it is urgent to design a CNC machine tool laser safety protection device to solve the above problems. Utility Model Content

[0011] Preferably, the lifting mechanism includes a servo motor, which is installed at the top of the right trapezoidal slider, and a threaded rod is installed at the bottom end of the servo motor.
