The workpiece is placed in the positioning groove 25, and the support plates 22 and the sliding plate 21 are respectively flat with different sides of the workpiece, so as to realize the positioning of the workpiece. The cutter bar 33 and the cutter head 34 are driven downward by the telescopic driving part 32, when the cutter bar 33 and the pull rod 35 move downward, the hanging plate 26 and the clamping plate 23 also move downward under the action of the elastic element 29 and clamp the workpiece in the positioning groove 25, realizing the clamping of the workpiece. Then the telescopic driving part 32 continues to drive the cutter head 34 to move downward, at this time the pull rod 35 is separated from the hanging plate 26, so that the cutter head 34 contacts the workpiece, so that the workpiece can be machined by the cutter head 34. After the workpiece is machined, the waste cut by the cutter head 34 falls downward through the blanking opening, and the machined workpiece remains in the positioning groove 25. Then the telescopic driving part 32 drives the cutter bar 33 and the cutter head 34 to move upward, so that the pull rod 35 contacts the hanging plate 26, the cutter bar 33 and the pull rod 35 drive the hanging plate 26 and the clamping plate 23 to move upward, so that the clamping plate 23 releases the workpiece, so that the workpiece can be taken out, and the machining is completed.

[0043] By arranging the blanking opening between the two support plates 22, the waste generated in the machining process can be discharged through the blanking opening, so that the machining of the notch which may generate waste is facilitated, and the advantage of good practicability is achieved.

[0044] Different cutter heads 34 are replaced on the cutter bar 33, and the width of the blanking opening is adjusted by moving the sliding plate 21 and the support plates 22 on the rack 11 to adapt to the size of the cutter head 34, so that notches of different sizes can be machined, further improving the applicability.

[0045] During the movement of the cutter bar 33 and the cutter head 34 to the workpiece, the elastic element 29 can drive the clamping plate 23 to clamp the workpiece, realizing the function of automatically clamping the workpiece. When the cutter bar 33 and the cutter head 34 move away from the workpiece, the pull rod 35 can also drive the hanging plate 26 and the clamping plate 23 to release the workpiece, realizing the function of automatically clamping the workpiece, and facilitating operation.

[0046] The connecting rod 13 is arranged obliquely, so as to provide the support plate 22 with support force in the oblique direction, and therefore the connecting rod 13 can provide the support plate 22 with vertical upward component force, so as to keep the structural stability of the workpiece and the support plate 22 during the process of being pressed from top to bottom and being processed, and to improve the structural stability.
