[0032] Reference Figure 1 - Figure 2The moving mechanism includes a knob 18, and the surface of the knob 18 is provided with anti-slip key patterns, which can increase the friction between the hand and the knob 18 and reduce the possibility of slipping.

The bottom of the workbench 3 is slidably installed on the circumferential surface of the screw rod 19. The workbench 3 makes a linear motion in the axial direction of the screw rod 19. The bottom of the workbench 3 is fixedly connected with a protrusion 20, and the top of the base 1 is provided with a groove 21. The protrusion 20 slides on the inner wall of the groove 21. The groove 21 guides the movement direction of the protrusion 20, so that the protrusion 20 makes a more precise linear motion, avoiding motion deviation when the workbench 3 is displaced, and increasing the processing accuracy.

[0033] Reference Figure 1 The cutting mechanism includes a stepper motor 23, which is fixedly mounted on the left side of the bracket 22.

The bottom of the slider 25 is fixedly connected with a laser cutting machine body 27, and the laser cutting machine body 27 works to cut the workpiece. The cutting mechanism also includes a limit plate 26, which is a long plate. The limit plate 26 is fixedly mounted on the side where the two groups of brackets 22 are close to each other. The number of the limit plates 26 is set to two groups. The side where the two groups of limit plates 26 are close to each other is slidably connected to the front and rear sides of the slider 25. The limit plate 26 limits the movement direction of the slider 25, so that the slider 25 is displaced in the left and right directions.

[0034] Working principle: When in use, the staff places the workpiece to be cut on the top of the workbench 3, and then starts the power supply of the electric cylinder 4. The electric cylinder 4 drives the transmission rod 5 to move to the right, and the transmission rod 5 moves to the right and drives the clamp 1 6 to move to the right, thereby pressing the workpiece between the clamp 1 6 and the clamp 2 8. Then the staff starts the power supply of the stepper motor 23, and the stepper motor 23 drives the screw rod 2 24 to rotate. The rotation of the screw rod 24 drives the slider 25 to move in the axial direction of the screw rod 24. When the slider 25 moves, the laser cutting machine body 27 at the bottom of the slider 25 can perform laser cutting on the surface of the workpiece.

[0035] After laser cutting one side of the workpiece, if it is necessary to cut the surface in other directions, the staff can rotate the turntable 17. The rotation of the turntable 17 drives the threaded rod 15 to rotate. Since the threaded rod 15 is threadedly installed in the thread groove 14, the threaded rod 15 will also move to the right when it rotates, and then drive the impeller plate 2 16 to move to the right. The impeller plate 2 16 moves to the right and is out of contact with the impeller plate 1 9. At this time, the impeller plate 1 9 loses its restriction and can rotate freely. Then the circular plate 11 is rotated by the control rod 12. The rotation of the circular plate 11 will drive The movable shaft 10 rotates, and the rotation of the shaft 10 will drive the impeller disk 1 9 and the clamp plate 2 8 to rotate. The rotation of the clamp plate 2 8 will drive the workpiece between the clamp plate 2 8 and the clamp plate 1 6 to rotate. When the workpiece rotates to a suitable angle, the staff rotates the turntable 17 in the opposite direction to make the impeller disk 2 16 and the impeller disk 1 9 fit together again. At this time, the raised blocks on the surface of the impeller disk 2 16 and the raised blocks on the surface of the impeller disk 1 9 squeeze and fit each other, thereby limiting the rotation of the clamp plate 2 8, thereby fixing the workpiece. At this time, laser cutting can continue.

[0036] The screw rod 19 can also be rotated by rotating the knob 18, so that the workbench 3 can move linearly in the axial direction of the screw rod 19, driving the workpiece on the workbench 3 to move in the front and rear directions, thereby increasing the working range of the laser cutting machine body 27.
