[0002] Milling cutters are cutting tools typically used in milling machines or processing machines to perform milling operations. They remove material at a fixed feed rate within the machine. Milling cutters come in several shapes and many sizes, with a choice of coatings, as well as helix angles and number of cutting faces.

[0003] The tool replacement structure of the CNC machining centers currently used is bloated and complicated, making it difficult to ensure rapid tool change, resulting in workers spending a long time installing the milling cutter, which is inconvenient for workers. In addition, when clamping the tool, there is generally unstable clamping, which affects the machining accuracy and may even cause the tool to fall off. Therefore, it is necessary to design a milling cutter that can be quickly replaced. Utility Model Content

[0007] In order to drive the second bidirectional screw to rotate, as a milling cutter that can be quickly replaced in the utility model, one end of the second bidirectional screw penetrates the inner wall of the frame and extends to one side of the outer surface of the frame, and one end of the second bidirectional screw is fixedly connected to a twisting disk.

[0008] In order to achieve an anti-slip function, as a milling cutter that can be quickly replaced in the utility model, an anti-slip pad is arranged on the inner surface of the frame.

[0009] In order to facilitate the sliding column to pass through the through cavity, as a milling cutter that can be quickly replaced in the utility model, a through cavity is opened on one side of the outer surface of the clamping block, and the inner wall of the through cavity is slidably connected with a sliding column, and the sliding column is fixedly connected to the anti-slip pad.

[0010] In order to fix the anti-slip pad, as a milling cutter that can be quickly replaced in the utility model, one side of the outer surface of the sliding column is threadedly connected with a fastening nut.

[0011] In order to achieve a limiting effect, as a milling cutter that can be quickly replaced in the utility model, one side of the outer surface of the second bidirectional screw is fixedly connected to a limiting disk.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. In the utility model, through the arrangement of the frame, the first bidirectional screw, the worm gear, the second bidirectional screw, the helical teeth, the clamping block and the lower sliding groove, when in use, the second bidirectional screw can drive the rotation of the helical teeth and make it mesh with the worm gear to drive the rotation of the worm gear. When the worm gear rotates, it can drive the rotation of the first bidirectional screw. At this time, the first bidirectional screw and the second bidirectional screw and the clamping block perform threaded motion, so that the clamping block moves on the first bidirectional screw and the second bidirectional screw and clamps the milling cutter. When the milling cutter needs to be removed, the second bidirectional screw can be rotated in the opposite direction, which is convenient for the rapid installation, disassembly and replacement of the milling cutter.

[0014] 2. In the utility model, through the arrangement of the clamping block, the anti-skid pad, the through cavity, the sliding column and the fastening nut, when in use, one end of the sliding column of the anti-skid pad is passed through the through cavity on the clamping block from the inner surface of the clamping block. At this time, the fastening nut is threadedly connected to one end of the sliding column, so that the position of the anti-skid pad is fixed by the fastening nut, so that the anti-skid pad is used to prevent the milling cutter from being clamped when it is running. When the fastening nut is unscrewed, the anti-skid pad can be removed to facilitate the replacement and maintenance of the anti-skid pad. BRIEF DESCRIPTION OF THE DRAWINGS
