[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] Reference Figures 1-5The present invention provides a milling apparatus for milling the inner cavity of a profile, comprising:

[0043] Base plate 1;

[0044] The outer cover 2 is set on the top surface of the base plate 1. Lifting mechanisms are respectively set on both sides of the inner cavity of the outer cover 2. Platform 3 is set on the top of the two lifting mechanisms. Platform 3 slides relative to the outer cover 2 through the two lifting mechanisms so that platform 3 extends out from the top of the outer cover 2. A fixing mechanism is set on one side of the top surface of platform 3 for fixing the profile body 4. A milling mechanism is set on the other side of the top surface of platform 3 for milling the inner cavity of the profile body 4.

[0045] The top surface of the sink 5 and platform 3 has a rectangular hole, and the sink 5 is fixed in the rectangular hole. The bottom surface of the sink 5 is fixed with a fan 6, and the input end of the fan 6 is connected to the inner cavity of the sink 5. The top surface of the inner cavity of the sink 5 is fixed with a ventilated shell 7, and the top surface of the ventilated shell 7 is set as an open end. Several filter holes are opened on the bottom inner wall of the ventilated shell 7. The inner cavity of the ventilated shell 7 is connected to the inner cavity of the sink 5 through the filter holes so as to collect milling chips in the ventilated shell 7.

[0046] The base plate 1 supports the outer cover 2, which is raised and lowered by a lifting mechanism. This allows for lowering the height of the fixing mechanism when fixing the profile, enhancing adaptability and reducing the difficulty of fixing the profile body 4. The milling mechanism is used to mill the inner cavity of the profile body 4. The set groove 5 not only fixes the ventilated shell 7 but also collects metal debris. Driven by the fan 6, a negative pressure is generated in the groove 5, allowing external air to pass through the filter holes, carrying the metal debris generated during milling into the ventilated shell 7 for collection. This facilitates the collection and treatment of metal debris and prevents metal debris from splashing during milling, ensuring a safe working environment.

[0047] Further optimization of the scheme includes the following milling mechanism:

[0051] Among them, the first direction, the second direction, and the third direction are perpendicular to each other.

[0052] The horizontal moving block 8 drives the milling component to slide horizontally, thereby milling the inner cavity of the profile body 4. The vertical moving block 9 moves through the vertical moving component. After the profile body 4 is fixed, it drives the milling component to approach the profile body 4 until it is directly below the profile body 4. The lifting component drives the milling component to move upward, thereby allowing it to enter the inner cavity of the profile body 4 for milling.

[0063] The milling motor 19 is fixedly connected inside the fixed frame 10. The output end of the milling motor 19 passes through the fixed frame 10 and is fixedly connected to the milling cutter head through the connector.

[0064] The milling motor 19 drives the milling cutter head to rotate, thereby realizing the milling action.
