[0032] In this embodiment, the suction pipe 2 5.3 is respectively provided with a clamping boss 5.18 and a clamping groove 5.19, and the external suction hose 5.1 is inserted into the suction pipe 2 5.3 and is firmly installed on the suction pipe 2 5.3 through the clamping boss 5.18 and the clamping groove 5.19; the suction pipe 2 5.3 is also provided with an external thread 5.20, and the suction pipe 3 5.2 is fixed to the suction pipe 2 5.3 through the internal thread provided on the suction pipe 3 5.2, thereby clamping the external suction hose 5.1.

[0033] The suction rack 5.7 of this embodiment is installed outside the machine head, two suction pipe racks 5.6 are installed on the upper part of the suction rack 5.7, and the suction pipe 5.5 is installed on the suction pipe rack 5.6. The suction pipe rack 5.6 is provided with a card slot 5.31, which is fastened by screws 5.32.

[0034] In this embodiment, an oil spray rack 5.10 is installed on the suction elbow 5.9, and an oil spray connector 5.11 is installed on the oil spray rack 5.10. The upper end of the oil spray connector 5.11 is connected to the thin oil lubrication system, and the thin oil lubrication system adopts standard purchased parts; an oil spray copper tube 5.12 is installed on the other end of the oil spray connector 5.11, and the oil spray copper tube 5.12 adopts a special-shaped structure, and the other end of the oil spray copper tube 5.12 is connected to the oil spray seat 5.14; the oil spray seat 5.14 is installed on the mounting recess 5.35 of the suction seat 5.16, and a suction soft brush 5.30 is installed on the outer ring of the oil spray seat 5.14, and an oil spray cover 5.15 is installed on the bottom of the oil spray seat 5.14.

[0035] The outer ring of the fuel injection seat 5.14 of this embodiment is provided with several fuel injection holes 5.23. Except for the fuel injection holes 5.23 installed with the fuel injection copper tube 5.12, the other fuel injection holes 5.23 are blocked with screw plugs 5.24; an oil-permeable ring 5.22 is also provided on the fuel injection seat 5.14. The oil-permeable ring 5.22 is a machined concave ring, which is mainly used for passing the fuel injection oil path 5.25. A circle of nozzles 5.26 are provided on the inner side of the oil-permeable ring 5.22, and the nozzles 5.26 are small hole devices.

[0036] The fuel injection cap 5.15 of the present embodiment is provided with a boss 5.27, which just matches with the oil-permeable ring 5.22. The height of the boss 5.27 is less than the depth of the oil-permeable ring 5.22. When the fuel injection cap 5.15 is installed on the fuel injection seat 5.14, a hollow structure is generated inside the fuel injection seat 5.14, through which the fuel injection oil passage 5.25 can pass.

[0037] The bottom of the oil spray seat 5.14 of this embodiment is provided with a plurality of chip grooves 5.28, which can guide the air flow. When the patented machine head is engraving and cutting materials, a large amount of chips will be generated. At this time, when the vacuum cleaner is powered on and starts to suck air, the external airflow of the suction soft brush 5.30 will pass through these chip grooves 5.28, forming a vortex phenomenon, so that the chip suction effect is enhanced, the chip adsorption is cleaner, and the table is tidier.

[0038] The suction seat 5.16 is installed on the suction mounting seat. The suction seat 5.16 is a cylindrical structure. The cylinder and the milling cutter cooling sleeve are matched with each other. The suction seat 5.16 can move up and down smoothly outside the milling cutter cooling sleeve without causing a small amount of air leakage.

[0039] A mounting platform 5.33 is provided on the suction seat 5.16, and a suction waist hole 5.34 is provided on the mounting platform 5.33; a suction elbow 5.9 is installed on the mounting platform 5.33 on the suction seat 5.16 and fixed by screws; the suction waist hole 5.34 and the suction elbow 5.9 are connected; the other end of the suction elbow 5.9 is connected to an internal suction hose 5.8; the other end of the internal suction hose 5.8 is connected to a suction pipe 1 5.5, and the external suction hose 5.1 is connected to a vacuum cleaner.

[0040] When the vacuum cleaner starts to suck air, suction will be generated at the mounting concave platform 5.35 of the suction seat 5.16, and suction will be generated at the suction soft brush 5.30. When the machine head is engraving or cutting materials, a large amount of chips will be generated. These chips will pass through the suction channel, the suction soft brush 5.30, the suction seat 5.16, the suction elbow 5.9, the internal suction hose 5.8, the suction pipe 1 5.5, the suction pipe 2 5.3, the suction pipe 3 5.2, and the external suction hose 5.1, and finally reach the vacuum cleaner. The structure is simple and firm, making the table clean and pollution-free during cutting, improving the operator's operating environment, and improving the dust cleanliness of the operating site.

[0041] The suction elbow 5.9 of this embodiment is provided with an air vent 5.21, and an adjusting ring 5.13 is installed on the suction elbow 5.9. When cutting small figures, the small figures are often sucked into the vacuum cleaner by mistake because the suction of the vacuum cleaner is too strong and the small figures are very light. At this time, the position of the adjusting ring 5.13 is adjusted to adjust the exposure size of the air vent 5.21 to adjust the strength of the suction.

[0042] Through the above description, those skilled in the art can already implement it.

[0043] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different, and the above content described in this specification is only an example of the structure of the present invention.
