[0038] Working principle: When in use, the user places the plastic shell to be cut on the lifting plate 13, and uses the forward and reverse motor 506 in the positioning clamping assembly 5 to drive the threaded rod 511 to rotate, lowering the height of the lifting frame 509, so that the lifting plate 13 moves to a state flush with the support rod 3, so that the plastic shell to be cut is placed on the support rod 3, and at the same time, when the lifting frame 509 is lowered, the meshing action of the tooth groove 510 and the gear 508 drives the movable frame 503 in the clamping arm structure to rotate, so that the buffer pressure seat 505 is placed above the plastic shell. At this time, the cylinder 504 is used to adjust the height of the buffer pressure seat 505 respectively, so that the buffer pressure seat 505 fits on the plastic shell, which is convenient for fixing the plastic shell, and then the XYZ three-axis gantry machine in the three-dimensional five-axis gantry fuselage structure 4 is used. The body structure and two rotating worktables adjust the position and angle of the laser cutting head and the high-power fiber laser to cut the plastic shell, and the support rod 3 is used to design the work surface on the chassis 1 for placing the plastic shell into a hollow shape, so that the waste chips generated during cutting can fall on the support inclined seat 8, and the waste chips are discharged from the waste outlet 7 with the vibration effect of the vibration motor 11, thereby realizing the function of facilitating waste discharge. After the cutting is completed, the three-dimensional five-axis gantry fuselage structure 4 is reset, and the positioning clamping assembly 5 and the clamping arm structure are also reset. At this time, as the height of the lifting frame 509 is adjusted, the lifting rod 12 and the lifting plate 13 are driven to adjust the height, so that the cut plastic shell is lifted up by the lifting rod 12 and the lifting plate 13 during discharging, so that it is separated from the cutting residue, which is convenient for material removal.
