[0002] The tool magazine door is an important part of a machining center, responsible for protecting the inside of the tool magazine during the tool change process, preventing foreign objects from entering the tool magazine, and ensuring the rapid, accurate replacement of tools. The design of the tool magazine door not only needs to consider the reliability and durability of the mechanical structure, but also the flexibility and intelligence of the control system to meet the requirements of different machining tasks.

[0003] However, in the prior art, the opening and closing structure design of the tool magazine door is relatively simple, usually relying on a single cylinder to directly drive the opening and closing. This simplified design will cause multiple problems in actual use. For example, the tool magazine door is prone to shaking or jamming during the opening and closing process. This unstable opening and closing movement not only affects the stability and reliability of the tool magazine door, but also may cause excessive wear or damage to mechanical components, increasing the risk of mechanical failures. In addition, the shaking and jamming phenomena will also have an adverse impact on the tools inside the tool magazine, which may cause the position deviation or damage of the tools, thereby affecting the machining accuracy and efficiency of the machining center. Therefore, improvements are needed. Summary of the Utility Model

[0023] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0024] Please refer to Figures 1 - 5 The utility model proposes a tool magazine door structure for a machining center, including a fixed frame 1, a tool magazine door body 2, and a driving mechanism 3. The surface of the fixed frame 1 is slidably connected with the tool magazine door body 2. The tool magazine door body 2 is made of austenitic stainless steel, has excellent corrosion resistance and high strength, can be used for a long time in a harsh working environment, and ensures the durability and stability of the tool magazine door body 2. A slideway is installed on the inner side of the fixed frame 1. The slideway can be a ball slideway or a linear slideway. Such a sliding connection method can ensure the stability and smoothness of the tool magazine door body 2 when opening and closing. The ball slideway can reduce friction and improve sliding efficiency, while the linear slideway provides higher guiding accuracy and bearing capacity, and prolongs the service life of the slideway. The driving mechanism 3 is installed on the back of the fixed frame 1. The back of the fixed frame 1 is fixedly installed with a mounting bracket 4. The mounting bracket 4 is arranged at an equal distance on the back of the fixed frame 1. The mounting bracket 4 can be fixed by riveting or welding. Riveting can provide good connection strength and seismic resistance, while welding ensures the overall rigidity and stability of the bracket.

[0025] The driving mechanism 3 includes a mounting frame 301, a cylinder 302, a push shaft 303, a rack 304, a gear 305, a side frame 306, and a top frame 307. The mounting frame 301 is fixedly installed on the back of the fixed frame 1. The mounting frame 301 can be fixed by bolt connection or welding. Bolt connection is convenient for disassembly and maintenance, while welding ensures the stability and precision of the mounting frame 301. The surface of the mounting frame 301 is fixedly installed with a cylinder 302. The cylinder 302 can be made of aluminum alloy or stainless steel. Aluminum alloy has a light weight and corrosion resistance, while stainless steel has higher strength and wear resistance, ensuring the long-term stable operation of the cylinder 302. The output end of the cylinder 302 is installed with a push shaft 303. The push shaft 303 can be connected by key connection or threaded connection to ensure the tight connection and stable transmission between the push shaft 303 and the cylinder 302. Key connection provides reliable torque transmission, and threaded connection is convenient for installation and adjustment. The inner wall of the mounting frame 301 is slidably connected with a rack 304. The rack 304 can be made of high-strength alloy steel or wear-resistant cast iron. High-strength alloy steel has excellent mechanical properties and wear resistance, while wear-resistant cast iron can maintain stable performance under high loads. The inner wall of the mounting frame 301 is rotatably connected with a gear 305. The gear 305 meshes with the rack 304. The gear 305 can be made of high-precision alloy steel or nickel-chromium alloy. High-precision alloy steel ensures the transmission precision and wear resistance of the gear 305, while nickel-chromium alloy has excellent corrosion resistance and high-temperature stability.

[0026] The push shaft 303 is fixedly connected to the rack 304. The surface of the gear 305 is fixedly installed with a side frame 306. One end of the side frame 306 is rotatably connected with a top frame 307. The top frame 307 is rotatably connected to the tool magazine door body 2. The top frame 307 can be made of high-strength aluminum alloy or engineering plastic. High-strength aluminum alloy provides excellent strength and corrosion resistance, while engineering plastic has a light weight and good impact resistance, ensuring the stability and reliability of the top frame 307 during the opening and closing process. The number of the gears 305, side frames 306, and top frames 307 is two groups. The two groups of gears 305, side frames 306, and top frames 307 are symmetrically distributed on both sides of the mounting frame 301. Such a symmetrical distribution can balance the force, ensuring that the tool magazine door body 2 does not shift or shake during the opening and closing process, and improving the overall operation stability.

[0027] In this embodiment, when opening the tool magazine door body 2, it is only necessary to drive the push shaft 303 to move downward through the air cylinder 302. Subsequently, the push shaft 303 can drive the rack 304 to slide within the mounting bracket 301. Then, the rack 304 can drive the gear 305 meshing with it to rotate clockwise. Subsequently, the gear 305 drives the side frame 306 to rotate clockwise, and the side frame 306 then drives the top frame 307 to unfold. During the unfolding process of the top frame 307, it can drive the tool magazine door body 2 to move upward. At this time, the tool magazine door body 2 can be opened. When closing the tool magazine door body 2, it is only necessary to drive the push shaft 303 to move upward through the air cylinder 302 to fold the top frame 307, so that the tool magazine door body 2 slides downward and is received under the fixed frame 1. The present utility model can realize the opening and closing operations of the tool magazine door by driving the push shaft 303 to move up and down through the air cylinder 302, which simplifies the operation process, reduces the operation steps, improves the convenience and efficiency of the operation. At the same time, the two top frames 307 push the tool magazine door body 2 to open and close, which can improve the opening and closing stability of the tool magazine door body 2 and avoid shaking when the tool magazine door body 2 opens and closes. The meshing transmission between the rack 304 and the gear 305 ensures the smoothness and reliability during the opening and closing process of the tool magazine door, reduces the possibility of mechanical failures, and extends the service life of the equipment. The rapid opening and closing design of the tool magazine door makes the tool change process faster, reduces the downtime, improves the production efficiency and productivity of the machining center, and meets the requirements of high-efficiency production.

[0028] Certainly, the present utility model can also have many other embodiments. Based on this embodiment, other embodiments obtained by those of ordinary skill in the art without any creative work belong to the scope protected by the present utility model.
