A protective cover 34 is fixed to the edge of the lower surface of the mounting plate 31, and the protective cover 34 protects the gear 33.

[0033] A placing plate 4 is arranged on the upper surface of the movable frame 2. A workpiece to be cut is arranged on the placing plate 4. A synchronous cylinder 24 is arranged on the inner side of the movable frame 2. The synchronous cylinder 24 drives the placing plate 4 to move and fine-tune the cutting position of the workpiece on the placing plate 4.

[0034] The clamping assembly 5 is arranged on the upper surface of the placement plate 4. The clamping assembly 5 clamps and limits the workpiece on the placement plate 4. The clamping assembly 5 includes a vertical plate 51 fixed at both ends of the upper surface of the placement plate 4. A clamping cylinder 52 is fixed in the middle of one side of the vertical plate 51. The output end of the clamping cylinder 52 is connected to a clamping plate 53. The clamping cylinder 52 drives the clamping plate 53 to move, so that the two clamping plates 53 can cooperate to clamp and limit workpieces of different models and sizes, thereby improving the working range of the device. The clamping plate 5 3 is located on the upper surface of the placement plate 4, a damping block 54 is bonded to one side of the clamping plate 53, and the setting of the damping block 54 plays a role of buffering and protecting the workpiece.

After the cutting accuracy of the device is adjusted, the connecting plate is moved upward until the damping strip 44 on the connecting plate contacts the placement plate 4, and then the screw 423 is turned until the screw 423 contacts the connecting plate to limit the connecting plate. At this time, the damping strip 44 plays a role of damping limit, limiting the placement plate 4 to ensure stable cutting of the workpiece, and then starting the motor 32, the motor 32 drives the gear 33 to rotate, the gear 33 cooperates with the rack 13 to drive the movable frame 2 to move until the movable frame 2 moves to the cutting piece, and the cutting machine on the cutting piece cuts the workpiece.
