[0002] A numerical control machine tool is short for a numerically controlled machine tool, which is an automated machine tool equipped with a program control system. The control system can logically process a program with control codes or other symbolic instructions, decode it, represent it in coded numbers, input it into the numerical control device through an information carrier, and after arithmetic processing, the numerical control device sends out various control signals to control the actions of the machine tool, and automatically processes parts according to the shape and size required by the drawing. With the continuous progress and development of modern economic technology, in the process of using a numerical control machine tool, an auxiliary instrument is often used, that is, an isolation door for a numerical control machine tool, which not only confines the generated waste materials and the like inside the machine tool, but also enables the staff to be in a safe working environment.

[0003] The patent with the patent number CN212420570U in the prior art introduces an isolation door for a numerical control machine tool, belonging to the technical field of numerical control machine tools, including a numerical control machine tool, one side of the numerical control machine tool is hinged with a door body, and an observation window is clamped inside the door body. Four rubber columns are fixed around one end of the outer wall of the observation window by bolts, and a plurality of first springs are installed around one end of the outer wall of the observation window by bolts, and the first springs are evenly located between every two rubber columns. One end of the rubber column is installed with a transparent acrylic plate by bolts. In the utility model, a sound insulation board is installed at one end of the outer wall of the door body, and the sound insulation board intercepts the noise generated inside the numerical control machine tool. The elastic block has excellent high tension, high tensile force, toughness and anti-aging properties. The elastic block intercepts the splashing waste materials to avoid the splashing waste materials directly contacting the door body. The elastic block and the second spring buffer the impact force of the splashing waste materials on the door body. The layer-by-layer protection of the elastic block and the sound insulation board further avoids the damage of the isolation door.

[0004] However, the patents in the prior art have the following several disadvantages:

[0005] (1) When the patents in the prior art are in use, the isolation door cannot be fixed, and the isolation door may slide during the operation of the machine tool.

[0006] (2) When the patents in the prior art are in use, the rotation speed of the cutter inside the machine tool is very fast, and it is easy to cause the coolant for cooling the cutter to splash onto the observation window, which affects the line of sight when the staff observes through the observation window. If the machining situation is not observed carefully, the machining quality may not be guaranteed. And because the isolation door is closed, it is very difficult to clean the inner side of the observation window, resulting in the staff stopping the machining to ensure the production quality, reducing the work efficiency.
