[0028] See also Figure 1-5 A tool magazine shield for a numerically controlled machine tool comprises a shield body 1, a cleaning mechanism 3 and an auxiliary mechanism 4. A tool magazine cavity 2 is provided inside the shield body 1.

[0029] The cleaning mechanism 3 includes a mounting groove 301 provided on the inner wall of the tool magazine chamber 2 , a servo motor 302 fixedly connected to the inner wall of the mounting groove 301 , and a flat gear 303 fixedly connected to the output shaft end of the servo motor 302 .

[0030] When the servo motor 302 is started, it drives the plane gear 303 to rotate.

[0031] The inside of the installation slot 301 is provided with a vent 309, which is located above the servo motor 302. The vent 309 can facilitate the circulation of air inside and outside the installation slot 301, avoid overheating of the servo motor 302, and help extend the service life of the device.

[0032] A disc-type tool magazine body 5 is installed on the inner wall of the tool magazine cavity 2. The disc-type tool magazine body 5 is an existing device and is not an innovative part of the present application, so it will not be described in detail.

[0033] The inner wall of the tool magazine chamber 2 is provided with a discharge port 310 , which is located below the disc tool magazine body 5 . The discharge port 310 can be provided to conveniently discharge the debris and waste liquid inside the tool magazine chamber 2 to the outside.

[0034] Two fixing rings 304 are fixedly connected to the inner wall of the tool magazine chamber 2 , and a rotatable gear ring 305 is installed between the two fixing rings 304 .

[0035] The gear ring 305 is installed between the two fixing rings 304 . The gear ring 305 can rotate between the two fixing rings 304 , but will not fall off from between the two fixing rings 304 .

[0036] The gear ring 305 meshes with the plane gear 303 , and the inner wall of the gear ring 305 is fixedly connected with uniformly distributed cleaning rods 306 , and the outer surface of each cleaning rod 306 is fixedly connected with uniformly distributed first cleaning brushes 307 and second cleaning brushes 308 .

[0037] The positions of the cleaning rod 306, the first cleaning brush 307 and the second cleaning brush 308 are arranged as follows: Figure 5 shown.

[0038] When the servo motor 302 starts to drive the flat gear 303 to rotate, it will drive the gear ring 305 meshing with the flat gear 303 to rotate. When the gear ring 305 rotates, it will drive the cleaning rod 306 to rotate. When the cleaning rod 306 rotates, it can drive the first cleaning brush 307 and the second cleaning brush 308 fixedly connected to its surface to rotate.

[0039] The first cleaning brush 307 is matched with the inner wall of the tool magazine cavity 2 , and the second cleaning brush 308 is matched with the disc tool magazine body 5 .

[0040] When the first cleaning brush 307 rotates, the inner wall of the tool magazine chamber 2 can be cleaned, which facilitates the cleaning of debris and waste liquid attached to the inner wall of the tool magazine chamber 2.

[0041] When the second cleaning brush 308 rotates, the disc tool magazine body 5 and the knives installed on the inner wall of the disc tool magazine body 5 can be cleaned conveniently, so as to prevent debris and waste liquid from adhering to the surface for a long time and affecting the normal operation of the disc tool magazine body 5.

[0042] The reason why the debris and waste liquid appear inside the tool magazine cavity 2 and on the surface of the disc tool magazine body 5 is that some of them tend to leak in through the gaps in the magazine door. In addition, during the machining of the machine tool spindle, although the debris, waste liquid and other waste materials will not directly splash into the tool magazine, they will splash to the inside of the tool magazine door. When they accumulate to a certain extent, they will naturally slide down along the inside of the tool magazine door.

[0043] The auxiliary mechanism 4 includes two protective plates 403. Two mounting frames 401 are fixedly connected to the outer surface of the shield body 1. Two cylinders 402 are installed on the side of the two mounting frames 401 close to each other. By setting the mounting frames 401 and the cylinders 402, other components can be easily driven to move.

[0044] The output ends of the four cylinders 402 are fixedly connected to the inner walls of the two protective plates 403 respectively. The two protective plates 403 are located on the front side of the shield body 1. The protective plates 403 can be used to protect the tool magazine cavity 2 to prevent debris and waste liquid from splashing into the tool magazine cavity 2 during processing of the CNC machine tool.

[0045] When tool changing is not required, the sides of the two protective plates 403 that are close to each other are in contact, which can protect the front side of the tool magazine cavity 2 and prevent debris and waste liquid from splashing into the tool magazine cavity 2 during processing of the CNC machine tool.

[0046] When the tool change operation is required, the corresponding two cylinders 402 will drive the corresponding protective plates 403 to move, and the two protective plates 403 will move away from each other and move to the position as shown in FIG. Figure 1 The status shown makes it easy to change the tool.

[0047] An air pump 404 is provided on the inner wall of the tool magazine cavity 2, and the top end of the air pump 404 penetrates the shield body 1 and extends to the outside of the shield body 1. The air pump 404 can be provided to facilitate the installation of other components.

[0048] A reserved groove 405 is installed on the inner wall of the air pump 404, and the output end of the reserved groove 405 is connected to the interior of the tool magazine cavity 2. The reserved groove 405 is an existing mechanism. The reserved groove 405 is not an innovative part in this application and has been mentioned in the description of the comparative document. Therefore, the working principle and internal structure of the reserved groove 405 will not be repeated.

[0049] By setting the reserved groove 405, high-pressure gas can be sprayed into the tool magazine chamber 2, and the cleaning mechanism 3 set up can clean the inner wall of the tool magazine chamber 2 and the disc tool magazine body 5 with higher quality, solving the problems existing in the comparative documents and preventing partially cleaned debris and waste liquid from adhering to the inner wall of the tool magazine chamber 2.

[0050] It should be noted that the reason why debris and waste liquid appear inside the tool magazine cavity 2 and on the surface of the disc tool magazine body 5 is that when the two protective plates 403 are pressed tightly together, there will be gaps, so some of them will often leak in through the gaps.

[0051] In addition, during CNC machine tool spindle cutting and other processing, although waste materials such as chips and waste liquid will not directly splash into the disc tool magazine body 5, they will splash to the outside of the shield body 1. When accumulated to a certain extent, they will naturally slide down along the shield body 1. At this time, when the tool is changed, there is a great possibility that the waste will fall onto the tool installed on the disc tool magazine body 5.

[0052] The specific implementation process of the utility model is as follows: when the CNC machine tool is processing, the two protective plates 403 are controlled by the cylinder 402 to be in a state of being close to each other, which can effectively prevent debris and waste liquid from splashing into the tool magazine cavity 2 during the CNC machine tool processing. When the disc tool magazine body 5 is changing the tool, the corresponding cylinder 402 will be started to make the two protective plates 403 move away from each other and move to the position as shown in the figure. Figure 1 When the tool change work is completed through the disc tool magazine body 5, the corresponding cylinder 402 will control the corresponding protective plate 403 to move, so that the two protective plates 403 move to a state of being close to each other, and then the reserved groove 405 can be started to spray high-pressure gas into the tool magazine cavity 2, so that the inner wall of the tool magazine cavity 2 and the disc tool magazine body 5 can be cleaned. At the same time, the servo motor 302 needs to be started to cooperate with the work of the reserved groove 405. When the servo motor 302 is started, it will drive the flat gear 303 to rotate, and when the flat gear 303 rotates, it will cause the gear ring 305 rotates between the two fixed rings 304, and the rotation of the gear ring 305 will drive the cleaning rod 306 to rotate. The rotation of the cleaning rod 306 can drive the first cleaning brush 307 on its surface to clean the debris and waste liquid attached to the inner wall of the tool magazine chamber 2, and clean the debris and waste liquid to the outside of the shield body 1 through the discharge port 310. At the same time, the rotation of the cleaning rod 306 can also drive the second cleaning brush 308 to rotate. The rotation of the second cleaning brush 308 can clean the surface of the disc tool magazine body 5, thereby achieving a better cleaning effect and being more practical.

[0053] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
