[0002] In the machining center CNC machine platform machining process of prior art, blowing mechanism plays a vital role. Blowing mechanism is mainly used to remove the debris generated in the processing area and cool the processing part to ensure the smooth progress of the processing process and the stability of the processing quality. However, the blowing hole design of the common machining center CNC machine platform currently has obvious deficiencies.

[0003] Specifically, the traditional CNC machine platform is usually equipped with only 1-2 blowing holes. This design results in extremely limited blowing range, which is difficult to cover the processing area comprehensively. In the actual processing process, due to the insufficient number of blowing holes, some areas of the processing area may not be effectively cleaned of debris and cooled, which not only affects the processing efficiency, but also may cause the decline of the processing quality.

[0004] In addition, the limited number of blowing holes also limits the flexibility in the processing process. In some complex processing tasks, it may be necessary to blow the processing part from multiple angles to ensure thorough removal of debris and smooth processing. However, due to the limitation of the number of blowing holes, this requirement is often not met.

[0005] Therefore, in view of the insufficient number of blowing holes and limited blowing range of the existing machining center CNC machine platform, it is necessary to develop a new type of blowing mechanism. The mechanism should have more blowing holes to achieve 360° dead angle-free blowing coverage, thereby comprehensively improving the processing efficiency and processing quality. SUMMARY

[0008] Further, the inner wall of the air outlet hole is reserved with threads, the threads are matched with the threads outside the threaded joint, and the threaded joint is screwed into the air outlet hole through the threads.

[0009] Further, the valve is a manual regulating valve, and the size of the air flow can be adjusted through the manual regulating valve.

[0010] Further, the bamboo joint pipe is formed by connecting a plurality of joints, the top of each joint is reserved with a ball groove, and the bottom of each joint is integrally connected with a universal ball joint.

[0011] Further, when the plurality of joints are connected, the universal ball joint is located inside the ball groove, and relative movement can occur between the universal ball joint and the ball groove, so as to realize universal adjustment of the whole bamboo joint pipe.

[0012] Further, the air passage is of a ring structure, and is used for uniformly distributing the entering gas in the distribution disc.

[0013] Further, the air inlet joint is connected with the air passage, and is used for introducing the gas delivered by the gas delivery pipe into the air passage.
