This CNC machine tool that is easy to replace and maintain tools can facilitate tool replacement through connecting plates, clamping plates, bolts, mounting plates, fixed frames, tool heads, fixed blocks, fixed plates, telescopic rods, pull rods, clamping blocks and second springs. Therefore, when the tools on the CNC machine tool are worn due to long-term use, it is convenient for people to replace the tools, avoiding affecting the normal operation of the CNC machine tool, reducing people's work pressure, meeting people's work needs, and improving the work efficiency of the CNC machine tool.

[0004] When maintaining the cutter head, the device needs to pull the rods on both sides at the same time to remove or install the cutter head. When installing the cutter head, one hand needs to hold the cutter head and the other hand needs to pull the rod. However, it is difficult for one hand to pull the rods on both sides at the same time. Therefore, it is difficult for a single person to install the cutter head with this device, which is very inconvenient for cutter head maintenance.

[0005] Therefore, it is necessary to provide a CNC machine tool with convenient tool maintenance to solve the above technical problems. Utility Model Content

[0032] The first connecting rod 14 is pulled forward again, and the first connecting rod 14 drives the gear 16 to rotate through the first rack 15, and the gear 16 drives the second rack 17 to slide to the left. The second rack 17 pulls another group of first pull rods 10 to slide to the left through the second connecting rod 18. At this time, the two groups of limit blocks 11 slide to both sides of the cutter head 8 respectively, and the cutter head 8 can be removed at this time. When the cutter head 8 is located inside the mounting groove 7, the limit block 11 can be reset by the elastic force of the first spring 13 after loosening the first connecting rod 14. At this time, the limit block 11 can fix the cutter head 8. It is very easy to install the cutter head 8 by one person through this mechanism, which is very convenient for maintaining the cutter head 8. The setting of the second spring 22 can make the pressure plate 5 buffer upward when it is impacted. The distance between the pressure plate 5 and the connecting plate 3 can be adjusted by rotating the first threaded cylinder 20 and the second threaded cylinder 21, so as to adjust the pressure on the second spring 22. The shorter the distance between the pressure plate 5 and the connecting plate 3, the greater the elastic force generated by the second spring 22. It is very convenient to adjust the distance between the pressure plate 5 and the connecting plate 3 through this mechanism.
