[0003] Publication No. CN219074584U discloses a gear hobbing machine. The patent implements the method of fixing a support on the top surface of the base, fixing an air pump on the support, fixing a conduit on the air pump, and fixing a collection box on the top surface of the base to start the cylinder and blow the iron chips remaining on the gear into the collection box. After the work is completed, the collection box is cleaned uniformly to achieve the effect of clean gears and no iron chips everywhere. However, the patent still has the following problems in actual use:

[0004] By starting the cylinder, the iron filings remaining on the gears are blown into the collection box. After the work is completed, the collection box is cleaned uniformly to achieve the effect of clean gears and no iron filings everywhere. However, in actual use, when hobbing is performed on gears of different sizes, the processing positions are different. When adjusting the position of the guide tube, the positions of the rotating rod 1 and the fixed rod can be adjusted. The position adjustment of the rotating rod 1 and the fixed rod is not convenient for limiting. The guide tube is directly connected to the air pump. When the air pump is blowing, the pressure is relatively high. If the position of the guide tube is not fixed, it is easy to cause the guide tube to shift during the blowing process.
