[0044] Referring to Figures 1 to 4 According to the first aspect of the present application, the tool magazine comprises a tool disc 100, a protective cover 200, a protection assembly 300 and a shell 400.

[0045] The tool disc 100 is provided with a plurality of tool mounting structures 110 along the circumferential direction, and the tool mounting structure 110 is used for fixing the tool 600;

[0046] The protective cover 200 is detachably connected with the tool disc 100, and the protective cover 200 is provided with a plurality of tool taking openings 210 along the circumferential direction, and the tool taking opening 210 corresponds to the tool mounting structure 110 one by one;

[0047] The protection assembly 300 is provided with a plurality of protection assemblies 300, and the plurality of protection assemblies 300 are arranged on the protective cover 200 along the circumferential direction, and the protection assembly 300 corresponds to the tool taking opening 210 one by one, and the protection assembly 300 can shield or open the tool taking opening 210;

[0048] The shell 400 is detachably connected with the tool disc 100 or the protective cover 200, and is located on the side of the protective cover 200 away from the tool disc 100.

[0049] It can be understood that the tool mounting structure 110 is used for fixing the tool 600, and a plurality of tool mounting structures 110 are arranged on the tool disc 100 along the circumferential direction, and the spindle can select and replace the tool 600 in any tool mounting structure 110 according to the machining requirement. The protective cover 200 and the shell 400 are arranged on the tool disc 100, which can shield most positions of the tool disc 100 to protect the tool disc 100, and the tool taking opening 210 of the protective cover 200 corresponds to the tool mounting structure 110 one by one, so that the spindle can pass through the tool taking opening 210 to change the tool relative to the tool mounting structure 110. When the tool mounting structure 110 is mounted with the tool 600, the protection assembly 300 opens the tool taking opening 210, and one end of the tool head 610 of the tool 600 will pass through the tool taking opening 210 and be located outside the protective cover 200. When the tool mounting structure 110 is empty, that is, the tool mounting structure 110 is not mounted with the tool 600 or is taken away by the spindle, the protection assembly 300 shields the tool taking opening 210 and shields the tool mounting structure 110, reduces the risk of debris splashing on the tool mounting structure 110 during the machining process of the spindle, thereby reducing the risk of the tool 600 attached to the tool mounting structure 110 in the subsequent installation, to ensure the assembly precision between the spindle and the tool 600, and ensure the machining quality of the workpiece.

[0050] And, since the protective cover 200 and the cutter head 100 are detachably connected, the shell 400 and the cutter head 100 or the protective cover 200 are detachably connected, so that the disassembly and assembly of the protective cover 200, the cutter head 100 and the shell 400 can be facilitated. The protection assembly 300 is arranged on the cutter head 100, so that the protection effect of the tool mounting structure 110 can be achieved only by modifying the cutter head 100, and the production cost is reduced.

[0051] It should be noted that when the tool 600 is fixed on the tool mounting structure 110, the tool handle 620 of the tool 600 is fixed in the tool mounting groove of the tool mounting structure 110. Therefore, when the tool 600 is mounted on the tool mounting structure 110, the debris cannot be attached to the tool mounting groove due to the obstruction of the tool 600. When the tool 600 is mounted on the tool mounting structure 110, even if the debris splashes to other places of the tool mounting structure 110 through the tool taking opening 210, the assembly between the main shaft and the tool 600 is less affected, and the assembly precision between the main shaft and the tool 600 can be ensured by protecting the empty tool mounting structure 110 by the protection assembly 300.
