Specifically, a milling machine can process planes and grooves, which can effectively improve the machining efficiency of the workpiece, thereby facilitating the machining operation. CN215847238U discloses a milling machine. When using a brush or other tool to clean, it is difficult to clean the debris at the edge of the groove, which on the one hand leads to a long cleaning time, and on the other hand the cleaning effect is relatively general, which brings considerable trouble to people's use; the milling machine can conveniently and quickly clean the iron filings in the groove, but the milling machine still has the following defects:

[0026] The extrusion protection component includes an extrusion column 4 arranged above the button 3, and the button 3 is directly opposite to the extrusion column 4 up and down. A protective transparent baffle 5 is installed on the top of the extrusion column 4 by hot-melt adhesive. A threaded sleeve bracket 6 is fixedly connected to the top of the protective transparent baffle 5 and near the middle position thereof, and a transmission screw 7 is connected to the internal thread of the threaded sleeve bracket 6. A guide frame plate 8 is slidably connected to the outer wall of the threaded sleeve bracket 6. The top of the transmission screw 7 extends to the top of the guide frame plate 8 and is coaxially fixedly connected to a reduction drive motor 9. The reduction drive motor 9 is fixedly connected to the guide frame plate 8, and the transmission screw 7 is rotatably connected to the guide frame plate 8 through a bearing.
[0027] A protective support plate 10 is welded to one side of the protective transparent baffle 5, and a linkage support plate 11 is welded to the other side of the protective transparent baffle 5. A support frame 12 is installed on one side of the guide frame 8. The guide frame 8 and the support frame 12 are welded together. A supporting protective frame 1 is also welded on the support frame 12 to facilitate the threaded sleeve bracket 6 to drive the protective transparent baffle 5 so that the protective support plate 10 and the linkage support plate 11 move downward synchronously. At the same time, the support frame 12 supports the guide frame 8 to increase the stability of the guide frame 8. A fixed clamping plate 13 is installed at the top of the milling platform 2 and at the position on one side of the button 3. A clamping cylinder 15 fixedly connected to the milling platform 2 is provided on one side of the fixed clamping plate 13, so that the workpiece can be placed between the clamping cylinder 15 and the fixed clamping plate 13. Starting the clamping cylinder 15 drives the clamping plate to clamp the workpiece and fix it on the fixed clamping plate 13, which can clamp and lock the workpiece. A threaded sleeve slider 16 is slidably connected to one side of the supporting and protective frame 1, and the internal thread of the threaded sleeve slider 16 is connected to a moving screw 17.

The pushing end of the cylinder 20 extends to the bottom of the sleeve shaft plate 19 and is fixedly connected to the milling motor 21. A milling cutter head 22 fixedly connected by bolts is inserted on the output shaft of the milling motor 21, so that when the extrusion column 4 contacts the button 3 to open the drive of the milling motor 21, the milling motor 21 drives the milling cutter head 22 to rotate at high speed, and the downward pressure cylinder 20 is started to drive the milling motor 21 to move downward. The milling motor 21 drives the milling cutter head 22 to rotate downward and contact the workpiece. At the same time, the transmission motor 18 is started to drive the moving screw 17 to rotate inside the supporting protection frame 1. The moving screw 17 drives the threaded sleeve slider 16 to move horizontally under the action of the thread. The threaded sleeve slider 16 drives the sleeve shaft plate 19 to make the downward pressure cylinder 20 drive the milling motor 21 to make the milling cutter head 22 move horizontally to mill the workpiece.

After the button 3 is squeezed, the milling motor 21 is turned on to drive and rotate. After the operator is protected, the milling motor 21 will be energized in series with the button 3. When the reduction drive motor 9 drives the transmission screw 7 to reverse inside the guide frame 8, the threaded sleeve bracket 6 drives the protective transparent baffle 5 to move the extrusion column 4 upward, and the extrusion column 4 no longer squeezes the button 3. The button 3 is reset to turn off the milling motor 21, so that the protection safety is effectively improved.
