[0002] A five-axis machining center, also known as a five-axis linkage machining center, is a high-tech, high-precision machining center specifically designed for machining complex curved surfaces. This type of machining center system has a significant impact on a country's aerospace, military, scientific research, precision instruments, high-precision medical equipment, and other industries. The five-axis linkage CNC machining center system is the only means of machining impellers, blades, marine propellers, heavy-duty generator rotors, steam turbine rotors, large diesel engine crankshafts, and more. Currently, the tool magazines used in five-axis machining centers are all externally mounted. After tool changing, the removed tool directly enters the tool magazine. Debris and other debris attached to the tool's surface can enter the gaps in the tool magazine, causing the tool to jam when entering or leaving the magazine. This leads to tool retrieval failure, affecting tool changing quality and efficiency, and easily causing tool jamming, thus impacting the machining center's working efficiency. Utility Model Content

[0019] Please see Figures 1-4The present invention provides the following technical solution: it includes a tool magazine body 1 and several tool holders 11. Two support frames 2 are symmetrically arranged on one side of the tool magazine body 1. An electric telescopic rod 21 is installed on one side of the support frame 2. A connecting frame 22 is provided at one end of the electric telescopic rod 21. The connecting frame 22 is slidably connected to the support frame 2. A rotating plate 3 is rotatably connected to one end of the support frame 2. A cleaning brush head 31 is detachably connected to one side of the rotating plate 3. A receiving box 4 is provided below the tool magazine body 1. An inner box 41 is detachably connected to the inner cavity of the receiving box 4. Limiting plates 42 are fixedly connected to both ends of the top of the receiving box 4.

[0020] In this embodiment: the tool magazine body 1 and several tool holders 11 in this novel invention have the main function of a tool magazine. Two support frames 2 are symmetrically arranged on one side of the tool magazine body 1. An electric telescopic rod 21 is installed on one side of each support frame 2. A connecting frame 22 is provided at one end of each electric telescopic rod 21, and the connecting frame 22 is slidably connected to the support frame 2. The support frame 2, the electric telescopic rod 21, and the connecting frame 22 form a structure that supports and drives the cleaning structure. A rotating plate 3 is rotatably connected to one end of each support frame 2. A cleaning brush head 31 is detachably connected to one side of the rotating plate 3. The rotating plate 3 and the cleaning brush head 31 form a structure for cleaning the tool heads. The cleaning assembly includes a receiving box 4 located below the tool magazine body 1. An inner box 41 is detachably connected to the inner cavity of the receiving box 4, and limit plates 42 are fixedly connected to both ends of the top of the receiving box 4. The receiving box 4, the inner box 41, and the limit plates 42 form a device for collecting debris cleaned from the tool head. When changing tool heads in the machining center, several tool holders 11 in the tool magazine body 1 rotate via a drive device, moving the tool head to be replaced to the discharge port position. A gripping device swaps the position of the finished tool head with the newly replaced tool head. After the swap, the tool holder 11 rotates back to its original position. Before the work is completed, one end of the cutter head passes between the two cleaning brush heads 31. At this time, the electric telescopic rod 21 drives the connecting frame 22 to move, shortening the distance between the two cleaning brush heads 31, so that the two cleaning brush heads 31 abut against the sides of the cutter head. In this invention, the rotating plate 3 is equipped with a self-rotating component, which drives the rotating plate 3 and the cleaning brush heads 31 to rotate at high speed at one end of the connecting frame 22, thereby cleaning the cutter head after work and removing the debris from its surface. The debris is collected by the receiving box 4. The inner box 41 is removed for cleaning at regular intervals. After the cutter head is cleaned, The electric telescopic rod 21 drives the connecting frame 22 to slide and reset, increasing the distance between the two cleaning brush heads 31. This prevents the movement of the tool head from being obstructed during tool changing, allowing it to pass smoothly between the two cleaning brush heads 31. As a result, this invention can clean the tool head after machining when changing the tool head, preventing workpiece debris attached to its surface from entering the tool holder 11 and getting stuck in the gaps. This would affect the smoothness of tool loading and unloading during tool changing, causing jamming and preventing the machining center from working properly. After cleaning the debris attached to the tool head surface, it is centrally processed to avoid the problem of debris entering the tool magazine body 1 and being difficult to clean.

[0021] A connecting block 23 is fixedly connected to one side of the connecting frame 22, and a connecting groove 231 is provided on one side of the support frame 2. The connecting frame 22 is slidably connected to the support frame 2 through the connecting block 23 and the connecting groove 231. By setting the connecting block 23 and the connecting groove 231, the connecting frame 22 and the support frame 2 are connected. Under the drive of the electric telescopic rod 21, the connecting frame 22 is driven to slide smoothly on one side of the support frame 2.

[0022] The top of the receiving box 4 is set with an open structure, and the receiving box 4 is fixedly connected to the support frame 2 through a mounting bracket; the receiving box 4 is connected to the support frame 2 to fix the support frame 2 and make it stably receive materials.

[0023] An opening 43 is provided on one side of the limiting plate 42, and the opening 43 is located at the center of one side of the limiting plate 42. The opening 43 on one side of the limiting plate 42 facilitates the blade to pass through the limiting plate 42 and enter between the two cleaning brush heads 31. At the same time, the limiting plate 42 can block the debris being cleaned, allowing the debris to fall into the inner cavity of the inner box 41.

[0024] The inner box 41 is slidably connected to the inner cavity of the receiving box 4. One end of the receiving box 4 is provided with a through groove, the length and width of which are equal to the width and height of the inner box 41. The inner box 41 is detachably connected to the inner cavity of the receiving box 4 for easy removal and cleaning.

[0025] The rotating plate 3 is configured as a circular structure, and the two cleaning brush heads 31 are arranged opposite each other. The receiving box 4 is located directly below the two rotating plates 3. The rotating plate 3 drives the cleaning brush heads 31 to rotate, and cleans the blades after the operation is completed.

[0026] Both support frames 2 are inclined, and one end of each support frame 2 is fixedly connected to the outer shell of the tool magazine body 1. The two support frames 2 are arranged opposite to each other. The support frames 2 install and support the components of the drive rotating plate 3, so that they are connected to the tool magazine body 1.

[0027] The working principle and usage process of this utility model are as follows: When changing the cutting head in a machining center, several tool holders 11 in the tool magazine body 1 are rotated by a drive device, causing the cutting head to be replaced to move to the discharge port position. A gripping device then swaps the position of the finished cutting head with the newly replaced cutting head. After the swap, before the tool holder 11 rotates back to its original position, one end of the finished cutting head passes between two cleaning brush heads 31. At this time, the electric telescopic rod 21 drives the connecting frame 22 to move, shortening the distance between the two cleaning brush heads 31, thereby allowing the two cleaning brush heads 31 to contact the cutting head. With the two sides of the head abutting each other, the rotating plate 3 in this invention is equipped with a self-rotating component, which drives the rotating plate 3 and the cleaning brush head 31 to rotate at high speed at one end of the connecting frame 22, thereby cleaning the working blade head and removing the debris from its surface. The debris is collected by the receiving box 4. The inner box 41 is taken out for cleaning every once in a while. After the blade head is cleaned, the electric telescopic rod 21 drives the connecting frame 22 to slide back to its original position, which increases the distance between the two cleaning brush heads 31, so as to avoid the movement of the blade head being hindered when changing blades, and allow it to pass smoothly between the two cleaning brush heads 31.
