[0036] The working principle and use process of this utility model:

[0037] First, place the large workpiece to be cut between the two clamping plates 9 and start the No. 1 motor 3, which will cause the No. 1 threaded rod 4 to rotate and the moving block 5 to move horizontally forward under the limiting action of the base 1, thereby driving the two oblique rods 6 to move. At this time, under the limiting action of the slide groove 8, the two connecting blocks 7 will move horizontally toward each other, and finally the two clamping plates 9 will move horizontally toward each other together, finally achieving rapid fixing efficiency of the large workpiece and improving the efficiency of the operator in fixing the large workpiece. When the large workpiece is fixed, start the No. 2 motor 13, which will cause the No. 2 threaded rod 14 to drive the driving wheel 15 to rotate, and drive the driven wheel 17 and the No. 3 threaded rod 16 to start rotating together through the transmission belt 18, so that the gantry vertical rod 19 will move horizontally to the right under the limiting action of the base 1.

[0038] When the milling cutter 26 moves to the top of the large workpiece to be cut, the first pneumatic cylinder 22 is started at this time, so that the protective shell 23 drives the milling cutter 26 to move vertically downward, and the third motor 24 is started at the same time, which will cause the rotating shaft 25 to drive the milling cutter 26 to rotate. When the top of the milling cutter 26 contacts the workpiece, the cutting operation will be performed. When the control panel 32 is in an idle state, the second pneumatic cylinder 27 is started, which will cause the sleeve rod 28 to move horizontally backward, so that the sleeve rod 28 squeezes and pushes the rotating plate 29 inside it, so that the rotating plate 29 rotates with the round rod 30 as the axis, and the round rod 30 drives the closing plate 31 to start rotating together. Finally, when the closing plate 31 rotates to a horizontal state, it will realize the sealing effect of the control panel 32, play a protective function for the control panel 32, and improve the service life of the control panel 32.
