An opening for replacing a drill bit is opened on the side wall of the protective cylinder 3. A sealing assembly is installed at the opening of the protective cylinder 3. A fixed cylinder 4 is fixedly connected to the protective cylinder 3. A tool changing assembly is installed in the fixed cylinder 4. The tool changing assembly includes a conversion motor 5 fixedly connected to the fixed cylinder 4. The output end of the conversion motor 5 is fixedly connected to a rotating shaft 6. The outer surface of the rotating shaft 6 is fixedly connected to a transmission gear 7. The inner wall of the protective cylinder 3 is rotatably connected to a rotating shaft. Plate 9, the inner surface of the rotating plate 9 is fixedly connected with a gear ring 8, and one side of the rotating plate 9 is fixedly connected with a clamping jaw 10, and there are multiple clamping jaws 10, which are arranged in a ring array along the central axis of the rotating plate 9, and a drill chuck 11 is clamped in the clamping jaw 10, and there are multiple drill chucks 11, which are arranged in a ring array along the central axis of the rotating plate 9, and drill bits of different diameters and lengths are installed in the multiple drill chucks 11. A through groove is provided on the side wall of the fixed cylinder 4, and the transmission gear 7 extends out of the through groove, and the transmission gear 7 is meshed with the gear ring 8. It should be noted that the deep hole drilling tool magazine is located near the spindle box of the machine tool.

[0021] When in use, first start the sealing assembly to open the opening, then start the cylinder 1 to make the drill chuck 11 reach the axis of the spindle box, then close the cylinder 1, start the conversion motor 5 to make the rotating shaft 6 drive the transmission gear 7 to rotate, at this time, since the transmission gear 7 is engaged with the gear ring 8, the rotation of the transmission gear 7 will drive the gear ring 8 to rotate, and then drive the rotating plate 9 to rotate, so that the clamping jaw 10 drives the drill chuck 11 to rotate, so that the drill chuck 11 to be used reaches the axis of the spindle box, and then the spindle box moves, so that the drill chuck 11 to be used is installed on the spindle box, and Then start the sealing assembly to close the opening, start the cylinder 1 to reset the protective tube 3. When replacing again, first clamp the drill chuck 11 installed on the spindle box in the clamping jaws 10 that do not clamp the drill chuck 11, and then start the conversion motor 5 to make the rotating shaft 6 drive the transmission gear 7 to rotate. At this time, since the transmission gear 7 is engaged with the gear ring 8, the rotation of the transmission gear 7 will drive the gear ring 8 to rotate, and then drive the rotating plate 9 to rotate, so that the clamping jaws 10 drive the drill chuck 11 to rotate, so that the drill chuck 11 to be used reaches the axis of the spindle box, and the drill chuck 11 can be replaced.

[0022] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the sealing assembly includes an opening and closing motor 12 fixedly connected to the inner wall of the protective tube 3, the output end of the opening and closing motor 12 is fixedly connected to a protective plate 13, the outer surface of the protective plate 13 is fixedly connected to a positioning rod 14, the bottom end of the positioning rod 14 is fitted with a positioning plate 15, the protective plate 13 is arranged at the end of the protective tube 3 and fits with the protective tube 3, the protective plate 13 is arranged at the opening part of the protective tube 3, the positioning plate 15 is fixedly connected to the outer surface of the protective tube 3, and is located below the opening part of the protective tube 3.

[0023] Before the cylinder 1 extends, the opening and closing motor 12 is first started to rotate the protective plate 13 upward, thereby opening the opening of the protective cylinder 3. After the drill chuck 11 is replaced, the opening and closing motor 12 works again to rotate the protective plate 13 downward until the positioning rod 14 contacts the positioning plate 15. At this time, the protective plate 13 seals the opening of the protective cylinder 3, thereby protecting the drill bit through the protective cylinder 3 and the protective plate 13, avoiding the scrap generated when the machine tool is working to scratch the drill bit, ensuring the sharpness of the drill bit, and extending the service life of the drill bit.

[0024] The above-described embodiments merely represent several implementation methods of the present invention.
