[0002] A CNC machining center is a highly automated machine tool that can automatically change tools and perform multiple processes on a workpiece that is clamped once. It is usually composed of mechanical equipment and a CNC system and is suitable for processing workpieces of complex shapes. The total tool magazine currently equipped with CNC machine tools mostly places tools (or tool holders) in a centralized manner. For tool magazines that store a large number of tools, the tools are usually stored on tool racks. When extracting the tool, the tool is directly clamped by the machine tool spindle or the tool to be used is transferred to the spindle through other tool transfer mechanisms for work.

4. A CNC machine tool processing method, applied to a CNC machine tool processing center as claimed in claim 3, characterized in that: The following steps are involved: S1: Adding a CNC machine tool tool: Open the tool library (402), install the splicing table (415) equipped with a new tool on the splicing table (415) connected to the moving block (414) through the connecting rod (416), and complete the addition of the new tool, or install a new connecting base (409) between the two mounting plates (406), thereby realizing the addition of the new tool, increasing the storage quantity and types of tools in the tool library (402), and meeting the diversified processing requirements; S2: Switching of the CNC machine tool tool; according to the processing requirements, the rotary motor (404) is controlled to start, so that the rotary motor (404) drives one of the rotary shafts (405) to rotate, and the two sprockets (407) on one of the rotary shafts (405) rotate synchronously, and cooperate with the chain (408) to drive the two sprockets (407) on the other rotary shaft (405) to rotate, and the connecting base (409) is moved to the exit of the tool magazine (402), and then the first forward and reverse motor (411) is started again as needed to make the threaded rod ( 412) rotates to drive the moving block (414) to move on the guide rod (413), and adjusts the position of each splicing table (415) as a whole so that the required tool can be moved above the exit, and then starts the telescopic cylinder (418) to drive one of the sliding rods (419) to move, so that the scissor-type telescopic rod (420) is unfolded, and drives the fixed plate (417) to move downward, so that the tool leaves the tool magazine (402), and the tool on the tool seat (403) is exchanged with the tool on the CNC machine tool body (2) through the tool changing device (3); S3: Tool cleaning: After the tool is replaced and returns to the tool magazine (402), it is transported to the top of the cleaning cylinder (501) by the sprocket (407) and the chain (408), and then transported to the inside of the cleaning cylinder (501) by the scissor-type telescopic rod (420) so that it contacts the brush cylinder (505). Then, the second forward and reverse motor (506) is turned on to rotate the first gear (507), drive the second gear (508) to drive the cleaning cylinder (501) on the rotating cylinder (503) to rotate, and the brush cylinder (505) cooperates with the flushing pipe (504) to brush the tool to remove the residue on the surface of the tool and reduce the wear of the tool. After brushing, the tool leaves the cleaning cylinder (501) and is then transported to the drying box (502) by the sprocket (407) and the chain (408). The drying box (502) dries the tool to remove water stains on the surface of the tool and reduce the risk of rust and corrosion of the tool.
