Description

Technical Field

[0001] The utility model relates to the field of milling cutters, in particular to a milling cutter with a self-cleaning structure. Background Art

[0002] A milling cutter is a multi-tooth rotary tool widely used in machining a variety of metal and non-metal materials. During milling, multiple teeth of the cutter work simultaneously, eliminating idle travel and achieving high cutting speeds, resulting in high productivity and minimal surface roughness. Milling cutters come in a wide variety of shapes and sizes, depending on their application.

[0003] Milling cutters generate a large amount of waste chips during milling. If the waste chips are allowed to accumulate, on the one hand, it will affect the milling accuracy, and on the other hand, it will affect the operator's operating line of sight, making the device less practical and difficult to meet the needs of industrial production.

[0011] Preferably, the air outlet holes are all located in the discharge chute.

[0012] Preferably, the second circular hole passes through the connecting block.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] In the present invention, when the tool body is milling, a large amount of debris is generated. The debris enters the discharge trough and is slowly discharged along the discharge trough. The fan blows air toward the first circular hole, and the air enters the air outlet along the first circular hole, the second circular hole and the third circular hole. The air outlet blows air outward to blow away the debris at the lower end of the discharge trough, prevent the lower end of the discharge trough from being blocked, and ensure that the debris is discharged smoothly.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Example: This example provides a milling cutter with a self-cleaning structure, see Figure 1-4 Specifically, it includes a tool body 1, a plurality of discharge grooves 11 are opened on the tool body 1, and the discharge grooves 11 are all spiral-shaped. A soot blowing mechanism is provided on the tool body 1, a thread groove 2 is opened on the upper end of the tool body 1, and a connecting block 21 is threadedly provided on the upper end of the tool body 1. A first circular hole 4 is opened in the mounting block 31, a second circular hole 41 is opened in the round rod 3, and a third circular hole 42 is opened in the tool body 1. A plurality of air outlet holes 43 are opened on the tool body 1, and the air outlet holes 43 are all connected with the third circular hole 42. The air outlet holes 43 are all located in the discharge groove 11, and the second circular hole 41 passes through the connecting block 21;
