The lifting plate 10 can rise and fall vertically along with the lifting action of the support column 2; the top of the lifting plate 10 is slidably connected to a first transverse plate 12, and the top of the first transverse plate 12 is slidably connected to a second transverse plate 19; the top of the second transverse plate 19 is detachably connected to a disassembly block 25, and the bottom of the disassembly block 25 is fixedly connected with several limiting rods 26 at equal intervals along the length direction; the top of the second transverse plate 19 is provided with several limiting holes 24 at equal intervals along the length direction corresponding to the positions of the limiting rods 26, and the limiting rods 26 can be inserted into the corresponding limiting holes 24 to realize the detachable fixing of the disassembly block 25 and the second transverse plate 19.

[0017] A horizontal limiting shaft 5 is fixedly connected to the outer wall of the bottom groove 3 near one end along its length. The bottom of the two scissor plate units of the lower scissor plate is rotatably connected to the limiting shaft 5 via a pin. Two parallel sliding grooves 7 extending along the length of the bottom groove 3 are provided at the other end of the bottom groove 3 away from the limiting shaft 5. A movable shaft 6 is slidably connected between the two sliding grooves 7. The top of the two scissor plate units of the lower scissor plate is rotatably connected to the movable shaft 6 via a pin.

[0018] The lower scissor lift plate and the upper scissor lift plate are connected by a connecting strip 8 at their junction. The tops of the two scissor lift plate units of the lower scissor lift plate are rotatably connected to the two ends of one of the connecting strips 8 via pins. The bottoms of the two scissor lift plate units of the upper scissor lift plate are rotatably connected to the two ends of the other connecting strip 8 via pins. The two connecting strips 8 are parallel to each other and extend along the length of the bottom groove 3. A threaded rod 11 is fixedly connected between the two connecting strips 8. A servo motor 9 is fixedly installed on the outer wall of one of the connecting strips 8. The output shaft of the servo motor 9 passes through the connecting strip 8 and is fixedly connected to one end of the threaded rod 11. The threaded rod 11 is screwed into the threaded hole in the middle of the other connecting strip 8. By driving the threaded rod 11 to rotate through the servo motor 9, the two connecting strips 8 can be moved horizontally relative to each other or towards each other, thereby driving the lower scissor lift plate to unfold or fold to adjust the height of the lifting plate 10.

[0019] Two No. 1 fixing blocks 15 are symmetrically fixedly connected to the left and right sides of the top of the lifting plate 10. A No. 1 lead screw 16 is horizontally rotatably connected between the two No. 1 fixing blocks 15. The No. 1 lead screw 16 is screwed into the screw hole at the bottom of the No. 1 transverse plate 12. A No. 2 servo motor 17 is fixedly installed on the outer wall of one of the No. 1 fixing blocks 15. The output shaft of the No. 2 servo motor 17 passes through the No. 1 fixing block 15 and is fixedly connected to one end of the No. 1 lead screw 16. The No. 1 transverse plate 12 can be moved back and forth in the horizontal direction by the No. 2 servo motor 17 driving the No. 1 lead screw 16 to rotate.

[0020] The lifting plate 10 has two horizontally extending slide rails 14 symmetrically fixedly connected to the front and rear sides of its top. The bottom of the first horizontal plate 12 has two sliders 13 symmetrically fixedly connected to the front and rear sides. The two sliders 13 are respectively embedded in the corresponding slide rails 14 and slide in cooperation with the slide rails 14 to restrict the first horizontal plate 12 to move only in the horizontal direction.

[0021] Among them, the front and rear sides of the top of the first transverse plate 12 are symmetrically fixedly connected to two second slides 18 extending in a direction perpendicular to the first slide 14. The front and rear sides of the bottom of the second transverse plate 19 are symmetrically fixedly connected to two second sliders 20. The two second sliders 20 are respectively embedded in the corresponding second slides 18 and slide in cooperation with the second slides 18 to restrict the second transverse plate 19 to move only in the horizontal direction perpendicular to the first slide 14.

[0022] Two second fixing blocks 21 are symmetrically fixed to the left and right sides of the top of the first transverse plate 12. A second lead screw 22 is horizontally rotatably connected between the two second fixing blocks 21. The second lead screw 22 is screwed into the screw hole at the bottom of the second transverse plate 19. A third servo motor 23 is fixedly installed on the outer wall of one of the second fixing blocks 21. The output shaft of the third servo motor 23 passes through the second fixing block 21 and is fixedly connected to one end of the second lead screw 22. The second transverse plate 19 can be driven to reciprocate along the horizontal direction perpendicular to the first slide rail 14 by the rotation of the second lead screw 22 driven by the third servo motor 23.

[0023] The disassembly block 25 is symmetrically equipped with clamps 28 on its front and rear sides, and the bottom of the clamps 28 is slidably connected to the top of the disassembly block 25. An electric telescopic rod 27 is fixedly connected to the rear side of the disassembly block 25. The output shaft of the electric telescopic rod 27 passes through the disassembly block 25 and is fixedly connected to a push block that is movably hinged to the rear side wall of the two clamps 28. The two clamps 28 can be opened and closed by driving the push block to move back and forth through the electric telescopic rod 27, so as to clamp or release the laser cutting head or other processing parts.

[0024] Specifically: A multi-directional adjustable support platform for a laser cutting machine. In use, the platform is first assembled and initially positioned. Fix the base 1 to the machine bed of the laser cutting machine or the ground, ensuring the verticality of the four corner locking support columns 2; install the bottom groove 3 at the top center of the base 1; the bottom of the two units of the lower scissor plate 4 is rotatably connected to the limiting shaft 5 by a pin, and the top is rotatably connected to the movable shaft 6 by a pin; the movable shaft 6 is embedded in the sliding groove 7 of the bottom groove 3 and can slide horizontally along the sliding groove 7; the bottom of the two units of the upper scissor plate 4 is pinned to the movable shaft 6, and the top is rotatably connected to the bottom of the lifting plate 10 by a pin; the four corners of the bottom of the lifting plate 10 are fixedly connected to the lifting end of the support column 2 with built-in ball screws or hydraulic cylinders, ensuring that the lifting plate 10 can rise and fall vertically with the support column 2.

[0025] Vertical height adjustment: Start the first servo motor 9, whose output shaft drives the threaded rod 11 to rotate; since the threaded rod 11 is threadedly engaged with the lower connecting bar 8, the lower connecting bar 8 moves in the horizontal direction, pushing the lower scissor plate 4 to unfold or fold, thereby driving the upper scissor plate 4 and the lifting plate 10 to rise and fall synchronously, by controlling the speed and rotation angle of the first servo motor.

[0026] Horizontal slack adjustment: After the lifting plate 10 is positioned, the second servo motor 17 is started, and its output shaft drives the first lead screw 16 to rotate. The first lead screw 16 is screwed into the screw hole at the bottom of the first transverse plate 12, pushing the first transverse plate 12 to move horizontally along the first slide rail 14 in the X-axis direction until the second transverse plate 19 reaches the target X coordinate position. Then, the third servo motor 23 is started, and its output shaft drives the second lead screw 22 to rotate, pushing the second transverse plate 19 to move horizontally along the second slide rail 18 in the Y-axis direction to reach the target Y coordinate position. The transverse displacement is recorded by the CNC system to ensure repeatability and positioning accuracy.

[0027] Workpiece clamping and unclamping: Select the appropriate disassembly block 25 according to the shape of the workpiece to be processed. For example, a disassembly block with a right-angle clamp is selected for rectangular plates, and a disassembly block with an arc-shaped clamp is selected for round workpieces. Align the limiting insertion rod 26 at the bottom of the disassembly block 25 with the limiting insertion hole 24 at the top of the second transverse plate 19 and insert it vertically to achieve quick fixation. Start the electric telescopic rod 27, and its output shaft pushes the push block 29 forward. Through the hinged connection between the push block 29 and the clamp 28, the two clamps 28 are pushed to retract towards the center until the workpiece is clamped. The clamping force can be adjusted by the stroke of the electric telescopic rod. After processing is completed, reverse the electric telescopic rod 27, and the clamp 28 releases the workpiece. After removing the workpiece, replace or disassemble the disassembly block 25 to complete one processing cycle.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
