Description

Technical Field

[0001] This utility model relates to the field of automatic tool magazine doors, and in particular to an automatic tool magazine door for an intelligent machining center. Background Technology

[0002] The automatic tool magazine door separates the machining area from the tool magazine area, preventing chips and cutting fluid from splashing into the tool magazine. When closed, it effectively prevents dust and moisture from entering the tool magazine, protecting the tools and the internal structure of the tool magazine. It also prevents operators from accidentally touching the tool magazine during machining and prevents personnel from coming into contact with moving parts when changing tools, reducing the risk of safety accidents.

[0003] Existing automatic tool magazine doors are installed on a door track on the machining center, and then the automatic tool magazine door is installed inside the door track. The door is opened and closed by pushing an electric push rod to slide the door inside the door track. When the electric push rod pushes the door to close, the door usually comes into direct contact with the door frame as it moves. Prolonged direct contact and collision can cause damage to the door. Therefore, we propose an automatic tool magazine door for intelligent machining centers. Utility Model Content

[0004] The main purpose of this invention is to provide an automatic door for the tool magazine of an intelligent machining center, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An automatic tool magazine door for an intelligent machining center includes a tool magazine box, a protective door on the front of the tool magazine box, a movable component on the protective door that can control the sliding of the protective door along the extension direction of the tool magazine box, and a buffer component on the back of the tool magazine box that can buffer the closing of the protective door.

[0007] Preferably, the moving component includes a limiting frame fixedly installed on the back of the protective door, and the inside of the tool magazine box has two horizontal limiting holes, with the limiting frame slidably connected inside the limiting holes.

[0008] Preferably, as an automatic tool magazine door of an intelligent machining center according to this utility model, the limiting frame has a threaded rod internally connected to it, one end of which is fixedly connected to a servo motor. The threaded rod is installed inside the positioning seat through a bearing, and the positioning seat is fixedly installed on the back of the tool magazine box.

[0009] Preferably, as an automatic door for the tool magazine of an intelligent machining center according to the present invention, the buffer assembly includes a bracket fixedly installed on the back of the tool magazine box, and a guide column is slidably connected inside the bracket.

[0010] Preferably, as an automatic tool magazine door of an intelligent machining center according to this utility model, one end of the guide column is fixedly connected to a push plate, the push plate is connected to the bracket by a support spring, and the end of the guide column away from the push plate is fixedly connected to a stop.

[0011] Preferably, as an automatic tool magazine door of an intelligent machining center according to this utility model, the upper and lower surfaces of the protective door are both fixedly connected with inclined frames.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The automatic tool magazine door of this intelligent machining center is designed with a coordinated arrangement of the tool magazine box, protective door, limit frame, limit hole, threaded rod, servo motor, bracket, guide column, push plate, support spring, and stop. When the protective door is closed, the operator starts the servo motor, causing it to rotate forward. This controls the threaded rod to rotate, allowing the limit frame to slide within the limit hole, resulting in smoother door movement. The protective door effectively blocks the opening of the tool magazine box, protecting the tools inside. When the protective door closes, the limit frame first contacts the push plate, compressing the support spring and causing the limit frame to slowly contact the inner wall of the limit hole. This effectively prevents the limit frame from directly impacting the limit hole, reducing the risk of collisions. Furthermore, the protective door is positioned in front of the tool magazine box, eliminating the need for it to slide inside the door frame, further preventing collisions and extending its service life.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] like Figure 1-5 As shown, an automatic tool magazine door for an intelligent machining center includes a tool magazine box 1, which is installed inside the machining center. Inside the tool magazine box 1 is a tool holder for storing tools, rotatably connected to the inside of the tool magazine box 1. The tool holder is driven by a drive motor, allowing it to rotate inside the tool magazine box 1, thereby rotating the tool to be replaced to the opening of the tool magazine box 1 for easy tool changing. A protective door 2 is provided on the front of the tool magazine box 1, and a moving component is provided on the protective door 2 to control its sliding along the extension direction of the tool magazine box 1. A buffer component is provided on the back of the tool magazine box 1 to buffer the closing of the protective door 2.

[0023] In practical use, through the coordinated arrangement of the tool magazine box 1, protective door 2, limit frame 3, limit hole 4, threaded rod 5, servo motor 6, bracket 8, guide post 9, push plate 10, support spring 11, and stop frame 12, when the protective door 2 is closed, the operator starts the servo motor 6 to make it rotate forward, which controls the threaded rod 5 to rotate, causing the limit frame 3 to slide inside the limit hole 4, making the movement of the protective door 2 more stable. The protective door 2 can then block the opening of the tool magazine box 1, protecting the tools inside. When the protective door 2 is closed, the limit frame 3 can first contact the push plate 10, compressing the support spring 11, so that the limit frame 3 slowly contacts the inner wall of the limit hole 4, effectively preventing the limit frame 3 from directly impacting the limit hole 4, reducing the impact of the limit frame 3. Furthermore, the protective door 2 is located in front of the tool magazine box 1, eliminating the need for the protective door 2 to slide inside the door frame, effectively preventing collisions with the protective door 2 and extending its service life.

[0024] In this embodiment, the moving component includes a limiting frame 3 fixedly installed on the back of the protective door 2. Both ends of the limiting frame 3 are fixedly connected to the protective door 2. The inside of the tool magazine box 1 is provided with two horizontal limiting holes 4. The limiting frame 3 can slide along the opening direction of the limiting holes 4. The limiting frame 3 is slidably connected inside the limiting holes 4. The inside of the limiting frame 3 is threadedly connected with a threaded rod 5. One end of the threaded rod 5 is fixedly connected to a servo motor 6. The threaded rod 5 is installed inside the positioning seat 7 through a bearing. The positioning seat 7 is fixedly installed on the back of the tool magazine box 1.

[0025] In practical use, driven by the servo motor 6, the threaded rod 5 can be rotated, causing the limit frame 3 to slide inside the limit hole 4, which can control the movement of the protective door 2, thereby realizing the closing and opening of the protective door 2.

[0026] In this embodiment, the buffer assembly includes a bracket 8 fixedly installed on the back of the tool magazine box 1. A guide post 9 is slidably connected inside the bracket 8. A push plate 10 is fixedly connected to one end of the guide post 9. The push plate 10 and the bracket 8 are connected by a support spring 11. Before the support spring 11 is subjected to the pressure of the limiting frame 3, the support spring 11 is in a supporting state. A stop frame 12 is fixedly connected to the end of the guide post 9 away from the push plate 10. When the support spring 11 is reset, the stop frame 12 can limit the guide post 9 to prevent the guide post 9 from detaching from the inside of the bracket 8.

[0027] In practical use, the buffer component is designed so that when the protective door 2 is closed, the limit bracket 3 will first contact the push plate 10 and compress the support spring 11, which can play a buffering role when the protective door 2 is closed.

[0028] In this embodiment, inclined frames 13 are fixedly connected to both the upper and lower surfaces of the protective door 2.

[0029] In practical use, the inclined frame 13 is designed so that when processing debris falls onto the protective door 2, the debris will roll off the inclined frame 13, preventing it from accumulating on the top of the protective door 2.

[0030] Working principle: When the protective door 2 is closed, the staff starts the servo motor 6 to make the servo motor 6 rotate forward, which can control the threaded rod 5 to rotate, so that the limit frame 3 slides inside the limit hole 4. The limit frame 3 can first contact the push plate 10 to compress the support spring 11, so that the limit frame 3 slowly contacts the inner wall of the limit hole 4, which can effectively prevent the limit frame 3 from directly impacting the limit hole 4 and reduce the impact of the limit frame 3.
