However, during workpiece machining, debris will splash out. After the debris splashes onto the surface of the transparent plate, scratches will be generated. After a long time, the transparent plate will become unclear. Therefore, the transparent plate needs to be replaced regularly, resulting in a high use cost of the protection device. Content of the Utility Model

After a long time, the transparent plate will become unclear. Therefore, the transparent plate needs to be replaced regularly, resulting in a high use cost of the protection device, and to propose a protection device for a numerical control machine tool.

[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0023] Embodiment 1, as Figures 1 - 5 shown, the present utility model provides a protective device for a numerically controlled machine tool, including a protective door 1 and a cover plate 10. Two notches are opened on the outer surface of the protective door 1. A rotary joint pipe 5 is fixedly connected to the inner surface of the notch. A reflecting mirror 6 is fixedly connected to the inner top of the rotary joint pipe 5. A first inclined pipe 7 is fixedly connected to one end face of the rotary joint pipe 5. A second inclined pipe 8 is fixedly connected to the other end of the rotary joint pipe 5. A side frame 3 is fixedly connected to the front surface of the protective door 1. An observation mirror 4 is fixedly connected to the top of the side frame 3. A handle 2 is fixedly connected to the front surface of the protective door 1. The cross section of the rotary joint pipe 5 is arranged in a V shape. The first inclined pipe 7 is located at the rear side of the protective door 1. The first inclined pipe 7 and the second inclined pipe 8 are equal in length. The first inclined pipe 7 and the second inclined pipe 8 have the same inclination angle. The side frame 3 is located below the second inclined pipe 8. The observation mirror 4 is matched with the position of the second inclined pipe 8.

[0024] The overall effect achieved by the entire Embodiment 1 is that when the protective device for the numerically controlled machine tool is in use, when machining a workpiece inside the numerically controlled machine tool, the protective door 1 is closed so that the numerically controlled machine tool is in a closed state, avoiding the chips generated during machining from splashing out and hurting the staff. After the protective door 1 is closed, in order to monitor the machining situation inside the numerically controlled machine tool in real time, through the combined use of the rotary joint pipe 5, the first inclined pipe 7, the second inclined pipe 8, the reflecting mirror 6 and the observation mirror 4, the principle of specular reflection can be used to observe the machining situation of the workpiece inside the numerically controlled machine tool from the outside of the protective door 1. When observing, the staff directly observes the observation mirror 4 from the outside position of the numerically controlled machine tool, referring to Figure 4As shown, since the inclination angles of the first inclined tube 7 and the second inclined tube 8 are fixed, the principle that the angle of incidence of light is equal to the angle of reflection is utilized, and the image of the workpiece inside the CNC machine tool enters the eyes of the operator through the continuous reflection of the reflector 6 and the observation mirror 4. At this time, the operator can directly view the machining situation of the workpiece inside the CNC machine tool from the position of the observation mirror 4. At this time, the first inclined tube 7 is in a downward inclined state inside the CNC machine tool. The first inclined tube 7 and the second inclined tube 8 cooperate to form an inverted V-shaped fold angle. When the debris splashes into the inner wall of the first inclined tube 7, it will be blocked. Therefore, the debris generated during the machining of the workpiece cannot pass through the first inclined tube 7 to the outside after splashing, and the operator can directly observe the machining situation of the workpiece with the protective door 1 closed. Compared with the existing observation method of installing a transparent plate, it is not easily damaged, has a longer service life, and effectively reduces the use cost.

[0025] Embodiment 2, as Figures 1 - 5 shown, clamping blocks 9 are symmetrically and fixedly connected to the outer surface of the second inclined tube 8 located on the upper side. The cover plate 10 is matched with the position of the second inclined tube 8. A supplementary light 11 is fixedly connected to the outer surface of the cover plate 10. Clasps 12 are symmetrically and fixedly connected to the outer surface of the cover plate 10. The clasps 12 are provided in a matching manner with the clamping blocks 9. The supplementary light 11 is located inside the second inclined tube 8.

[0026] The overall effect achieved by the entire Embodiment 2 is that through the arrangement of a set of adapter pipes 5 on the upper side and the installation of the cover plate 10, after the supplementary light 11 installed on the surface of the cover plate 10 is turned on, the light source generated by it can enter the inside of the CNC machine tool through the refraction of the upper reflector 6, so as to supplement light for the inside of the CNC machine tool on the outside, making the observation picture of the observation mirror 4 clearer.

[0027] Working principle: When the protective device of the CNC machine tool is in use, after the protective door 1 is closed, in order to monitor the machining situation inside the CNC machine tool in real time, through the combined use of the adapter pipe 5, the first inclined pipe 7, the second inclined pipe 8, the reflector 6 and the observation mirror 4, the principle of specular reflection can be utilized to observe the machining situation of the workpiece inside the CNC machine tool from the outside of the protective door 1. At this time, the operator can directly view the machining situation of the workpiece inside the CNC machine tool from the position of the observation mirror 4. At this time, the first inclined pipe 7 is in a downward inclined state inside the CNC machine tool. The first inclined pipe 7 and the second inclined pipe 8 cooperate to form an inverted V-shaped corner. When the debris splashes into the inner wall of the first inclined pipe 7, it will be blocked. Therefore, the debris generated when the workpiece is machined cannot pass through the first inclined pipe 7 to the outside, and the operator can directly observe the machining situation of the workpiece with the protective door 1 closed. Compared with the existing observation method of installing a transparent plate, it is not easily damaged, has a longer service life, and effectively reduces the use cost. Through the setting of a group of adapter pipes 5 on the upper side and the installation cover plate 10, after the supplementary light lamp 11 is turned on, the light source generated by it can enter the inside of the CNC machine tool through the refraction of the upper reflector 6, so that the inside of the CNC machine tool can be supplemented with light on the outside, making the observation picture of the observation mirror 4 clearer.

[0028] The above are only the preferred embodiments of the present invention, and do not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
