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.

[0044] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0045] like Figure 1-5 As shown, an automatic safety door for a machining center 1 includes a left door leaf 2 and a right door leaf 3 disposed in the operation window 11 of the machining center 1. The machining center 1 is provided with a door leaf receiving area 12 on the left side of the operation window 11.

[0046] The left door leaf 2 and the right door leaf 3 are staggered and arranged in a staggered manner. Above the left door leaf 2 and the right door leaf 3 and the operation window 11, there is a bracket 4 extending to the door leaf receiving area 12, and below it is a lower guide mechanism 5.

[0047] The bracket 4 is equipped with a drive device, which includes a left door drive assembly 6 and a right door drive assembly 7. The left door drive assembly 6 is located in front of the right door drive assembly 7.

[0048] The left door drive assembly 6 includes a left door guide mechanism 61 and a left door driver 62 connected to the bracket 4. The left door 2 is slidably connected to the bracket 4 through the left door guide mechanism 61.

[0049] The right door drive assembly 7 includes a right door guide mechanism 71 and a right door drive driver 72 connected to the bracket 4. The right door 3 is slidably connected to the bracket 4 through the right door guide mechanism 71.

[0050] The bracket 4 is also equipped with a left door leaf positioning detection mechanism 8 and a right door leaf positioning detection mechanism 9.

[0051] It also includes a control module (not shown in the figure) that is electrically connected to the left door leaf position detection mechanism 8, the right door leaf position detection mechanism 9, the right door leaf driver 72 and the left door leaf driver 62.

[0052] In this embodiment, when the door is opened, under the control of the control module, the right door driver 72 is first controlled to drive the right door 3 to move towards the door storage area. After a set time, the left door driver 62 is then controlled to drive the left door 2 to move towards the door storage area (the right door 3 moves first, and the left door 2 moves later). When the left door positioning detection mechanism 8 and the right door positioning detection mechanism 9 are triggered in sequence, it indicates that the right door 3 and the left door 2 are fully open and have reached the set position. When the door is closed, the right door driver 72 is first controlled to drive the right door 3 to move towards the operation window 11. After a set time, the left door driver 62 is then controlled to drive the left door 2 to move towards the operation window 11 (the right door 3 moves first, and the left door 2 moves later). When the left door positioning detection mechanism 8 and the right door positioning detection mechanism 9 are triggered in sequence, it indicates that the right door 3 and the left door 2 are fully closed and have reached the set position.

[0053] With the above structure, the opening and closing of the door panels are automatically controlled, preventing them from colliding with each other and avoiding malfunctions or damage caused by collisions. This ensures stable and reliable operation and extends the service life of the doors.

[0054] Furthermore, such as Figure 1 , 2As shown in Figures 3, 4, and 5, in order to achieve independent driving of the right door leaf 3 and the left door leaf 2 to slide, both the right door leaf guide mechanism 71 and the left door leaf guide mechanism 61 include a slide rail 20 and at least two pulley assemblies 30.

[0055] The slide rail 20 is fixedly connected to the bracket 4, and the pulley assembly 30 is slidably connected to the slide rail 20 without separation.

[0056] The drive end of the left door driver 62 is connected to the left door 2 via the pulley assembly 30;

[0057] The drive end of the right door drive 72 is connected to the right door 3 via the pulley assembly 30.

[0058] Furthermore, such as Figure 3 As shown, in order to prevent the door leaf from tilting, improve the stability of the sliding connection, and ensure that the right door leaf 3 and the left door leaf 2 slide smoothly and steadily, the pulley assembly 30 includes a pulley mounting plate 301, at least two upper pulleys 302 and at least two lower pulleys 303.

[0059] The drive end of the right door driver 72 is connected to the right door 3 via a pulley mounting plate 301, and the drive end of the left door driver 62 is connected to the left door 2 via a pulley mounting plate 301.

[0060] The upper pulley 302 and the lower pulley 303 are slidably connected to the upper and lower surfaces of the slide rail 20, respectively, and the upper pulley 302 and the lower pulley 303 are rotatably mounted on the pulley mounting plate 301.

[0061] Furthermore, such as Figure 3 As shown, in order to improve load performance and transmission stability, as well as extend service life in dusty environments, both the upper pulley 302 and the lower pulley 303 are V-shaped pulleys.

[0062] Furthermore, such as Figure 1 , 2 As shown in Figure 4, the right door leaf driver 72 is a slide cylinder, and the slide of the slide cylinder is connected to the pulley mounting plate 301; the left door leaf driver 62 is a guide rod cylinder, and the driving end of the guide rod cylinder is connected to the pulley mounting plate 301.

[0063] In this embodiment, since the right door 3 has to pass through the left door 2 and the door storage area when it opens or closes, while the left door 2 only needs to pass through the door storage area when it opens or closes, the travel distance of the right door 3 is longer than that of the left door 2. Therefore, the guide rod cylinder cannot be used to drive the opening or closing of the right door 3, thus achieving a reasonable and reliable drive design.

[0064] Furthermore, such as Figure 1As shown, in order to accurately control the opening or closing of the left door 2 and the right door 3 and avoid overtravel and impact, the left door position detection mechanism 8 includes a first opening position sensor 81 and a first closing position sensor 82 connected to the bracket 4.

[0065] The first open position sensor 81 and the first closed position sensor 82 are located at the two ends of the slide cylinder, respectively;

[0066] The right door leaf positioning detection mechanism 9 includes a second open positioning sensor 91 and a second closed positioning sensor 92 connected to the bracket 4.

[0067] In this embodiment, during the sliding cylinder driving process, the first open position sensor 81 or the first close position sensor 82 controls the sliding cylinder to stop running by contacting the sliding table, and the same applies to the guide rod cylinder; thereby achieving precise control of the door opening or closing position; specifically, an electrical signal is sent to the control module, and then the control module controls the opening and closing of the solenoid valve to control the start and stop of the sliding cylinder.

[0068] Furthermore, such as Figure 1 , 3 As shown, in order to automatically unlock when the door is opened and automatically lock when it is closed, thereby improving security, an electronic lock 10 electrically connected to the control module is provided between the right door 3 and the machining center 1.

[0069] Furthermore, in order to observe the situation inside the processing center 1 when the doors are closed, observation windows 40 are provided on both the left door 2 and the right door 3.

[0070] Furthermore, such as Figure 4 , 5 As shown, in order to improve the overall stability of the door movement; furthermore, the lower guide mechanism includes a first lower guide bar 51, a second lower guide bar 52, a first deep groove ball bearing 53, and a second deep groove ball bearing 54;

[0071] The first lower guide bar 51 is connected to the machining center, and the first lower guide bar 51 extends from one end of the operation window 11 to the door storage area 12;

[0072] The second lower guide bar 52 is connected to the lower end of the left door leaf 2, and guide grooves are provided in the second lower guide bar 52 and the first lower guide bar 51;

[0073] The first deep groove ball bearing 53 is rotatably connected to the lower end of the right door leaf 3 through the first connector 50. There are two first deep groove ball bearings 53, one of which is slidably connected to the guide groove of the first lower guide bar 51, and the other is slidably connected to the guide groove of the second lower guide bar 52.

[0074] The second deep groove ball bearing 54 is rotatably connected to the lower end of the left door leaf 2 via the second connector 60. There are multiple second deep groove ball bearings 54, which are slidably connected to the guide groove of the first lower guide bar 51.

[0075] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model patent.
