The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] Figures 1-3 The present invention provides an external protective door opening device, which includes a door frame 200 and a protective door body 100 located on the door frame 200. The external protective door opening device also includes a linear guide rail 300, a slider 400 and a rotating shaft 500. The slider 400 is located on the linear guide rail 300 and is slidably connected to the linear guide rail 300.

[0025] Specifically, the door frame 200 and the protective door body 100 are obtained by bending and welding.

[0026] The linear guide rail 300 includes a first upper spindle 301, a second upper spindle 302, and a lower spindle 303. The first upper spindle 301 and the second upper spindle 302 are at the same height and form an angle with each other. The first upper spindle 301 and the lower spindle 303 are parallel to each other. The arc-shaped door of this application adopts an upper arc structure, which achieves smooth operation without jamming or derailment, and avoids the technical difficulty of keeping the upper guide rail, lower guide rail, protective door body 100, and outer protective door frame 200 concentric when the original arc-shaped protective door adopts an upper and lower arc structure.

[0027] Specifically, the length of the second upper spindle 302 is less than the length of the first upper spindle 301.

[0028] In a preferred embodiment, the angle formed by the first upper spindle 301 and the second upper spindle 302 is an obtuse angle.

[0029] The slider 400 includes a first slider 401, a second slider 402 and a third slider 403. Specifically, the first slider 401 is located on the first upper spindle 301, the second slider 402 is located on the second upper spindle 302, and the third slider 403 is located on the lower spindle 303.

[0030] The rotating shaft 500 includes a first rotating shaft 501 and a second rotating shaft 502. One end of the first rotating shaft 501 is rotatably connected to the upper surface of one side of the protective door body 100, and the other end is slidably connected to the first upper spindle 301 through the first slider 401. One end of the second rotating shaft 502 is rotatably connected to the upper surface of the other side of the protective door body 100, and the other end is slidably connected to the second upper spindle 302 through the second slider 402.

[0031] The first rotating shaft 501 and the second rotating shaft 502 are on different sides. Specifically, for ease of description, as follows... Figure 1 , Figure 2 As shown, the first rotating shaft 501 is located on the inner side of the left side of the protective door body 100, and the second rotating shaft 502 is located on the outer side of the right side of the protective door body 100. This allows the protective door body 100 to open in an arc shape. This opening and closing mechanism allows for a large-size door opening within a limited space, facilitating the entry and exit of machine tools.

[0032] The rotating shaft 500 also includes a third rotating shaft 503. One end of the third rotating shaft 503 is rotatably connected to the lower surface of the protective door body 100, and the other end is slidably connected to the lower spindle 303 through the third slider 403.

[0033] Specifically, the number of 500 rotating shafts is equal to the number of 400 sliders.

[0034] The external protective door opening device also includes a mounting base 600, and the linear guide rail 300 is fixedly connected to the door frame 200 through the mounting base 600.

[0035] Specifically, there are multiple mounting bases 600, and the number of mounting bases 600 is twice the number of sliders 400.

[0036] The external protective door opening device also includes limit blocks 700, which are located at both ends of the linear guide rail 300 and fixedly connected to it. The limit blocks 700 restrict the movement range of the slider 400, preventing it from exceeding the predetermined stroke of the linear guide rail 300, thereby protecting the device from running too smoothly.

[0037] Specifically, the number of limit blocks 700 is equal to the number of mounting bases 600.

[0038] A machine tool, including an external protective door opening device.

[0039] In use, the external protective door opening device of this application forms an angle between the vertical planes where the first upper spindle 301 and the second upper spindle 302 are located. The slider 400 moves linearly along the three linear guide rails 300 and is driven by the rotating shaft 500 located between the protective door body 100 and the slider 400 to realize the arc opening and closing of the protective door body 100. This application discloses an external protective door opening device and machine tool. The door opening method combines a linear guide rail 300 with a rotating shaft 500, with both upper and lower parts connected by spindles to increase reliability. The first upper spindle 301 and the second upper spindle 302 are located at the same height and form an angle with each other. While the slider 400 moves linearly along the spindle, the arc opening and closing of the protective door body 100 is achieved. This allows for a large-size door opening within a limited space, facilitating the entry and exit of machine tools. The main structure is composed of a door frame 200, a protective door body 100, and standard parts. The door frame 200 and the protective door body 100 have simple structures and can be obtained by bending and welding, resulting in a simple process with a low error rate. This avoids the use of unnecessary molds and rolling equipment, thus reducing costs. The connection method of the upper and lower spindles effectively prevents the protective door body 100 from derailing. The user-friendly installation method reduces assembly errors, avoids installation mistakes by assembly personnel, and improves assembly efficiency.

[0040] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
