Description

Technical Field

[0001] This utility model relates to the field of stone processing machine tool technology, and in particular to a CNC machine tool for stone surface treatment. Background Technology

[0002] In the fields of architectural decoration, landscape engineering and cultural and creative products, hard stone materials such as marble, granite and bluestone are widely used in surface decoration processing due to their hard texture and beautiful appearance. As the market demands for stone surface precision (such as flatness and texture consistency) and processing efficiency continue to increase, the equipment used in traditional stone processing has many drawbacks that cannot be ignored.

[0003] Traditional stone processing equipment suffers from several unavoidable drawbacks. Some traditional machines rely solely on simple clamps to secure the stone, a method prone to loosening under external force. Furthermore, over extended processing, the weight of the stone and vibrations cause the clamping effect to gradually deteriorate, impacting precision and quality. Additionally, traditional equipment lacks flexibility in adjusting processing positions, limiting it to simple straight or planar operations. It falls short when dealing with complex stone surface treatments, such as carving and polishing to create three-dimensional and layered patterns. Therefore, improvements are needed to address these issues. Utility Model Content

The second lead screw 14 is threadedly connected to one end of the mounting plate 13, and a first guide rod is provided at the front end of the second lead screw 14. The first guide rod is inserted into the other end of the mounting plate 13. A second motor 23 is installed inside the mounting plate 13, which facilitates the rotation of a third lead screw 15. The output end of the second motor 23 is mounted on the third lead screw 15 via a coupling, which facilitates the movement of the mounting base 16.

[0024] In this utility model, a second guide rod is provided at the front end of the third lead screw 15, and a mounting base 16 is threaded onto the third lead screw 15, which facilitates the installation of the third motor 17. The second guide rod is inserted into the mounting base 16, and the third motor 17 is installed inside the mounting base 16, which facilitates the driving of the second worm gear 18 to rotate.

The fourth lead screw 20 is fixedly connected to the center of the second worm wheel 19, which facilitates the driving of the fourth lead screw 20 to rotate. The four lead screws 20 facilitate the lifting and lowering of the fourth motor 25; the fourth motor 25 is threaded onto the fourth lead screw 20, which facilitates the rotation of the water cutter 24; the water cutter 24 is installed at the output end of the fourth motor 25; the water tank 5 is connected to the water pump 21 through a hose, which facilitates the extraction and pressurization of cooling liquid from the water tank 5; the output end of the water pump 21 is connected to the pressurizing nozzle 22 through a hose, which facilitates the spraying of cooling liquid onto the cutting area; the pressurizing nozzle 22 is located on one side of the water cutter 24; the positioning box 6 has a cavity inside; the upper middle part of the positioning box 6 has a sliding groove that matches the positioning plate 11; and multiple through slots are equidistantly provided on both sides of the sliding groove.

[0025] Working Principle: When using this invention, first connect the power supply to the device, then open the double-door 2 and place the stone to be processed on the positioning box 6. Turn the hexagonal nut 7 using an Allen wrench. The hexagonal nut 7 drives the first worm gear 8 to rotate. Since the first worm gear 8 meshes with the first worm wheel 9, the first worm wheel 9 drives the first lead screw 10 to rotate. The positioning plate 11 on the first lead screw 10 moves linearly along the first lead screw 10, thus stably fixing the stone on the positioning box 6, preventing the stone from shaking during processing and ensuring processing accuracy. Next, the equipment is started. The first motor 12 starts, and its output drives the second lead screw 14 to rotate. Since the second lead screw 14 is threadedly connected to one end of the mounting plate 13, and the first guide rod is inserted into the other end of the mounting plate 13 to provide guidance, the mounting plate 13 will move laterally under the drive of the second lead screw 14, thereby realizing the lateral position adjustment of the water cutter 24. When the water cutter 24 needs to move in the longitudinal direction, the second motor 23 inside the mounting plate 13 is started. The output of the second motor 23 drives the third lead screw 15 to rotate, and the third lead screw 15 is screwed... The mounting base 16, with its threaded connection, moves longitudinally along the third lead screw 15 under the guidance of the second guide rod, thereby driving the water cutter 24 to move longitudinally. To move the water cutter 24 vertically, the third motor 17 inside the mounting base 16 is activated. The output of the third motor 17 drives the second worm gear 18 to rotate. The second worm gear 18 meshes with the second worm wheel 19, which in turn drives the fourth lead screw 20 to rotate. The fourth motor 25, threaded onto the fourth lead screw 20, moves vertically along the fourth lead screw 20, thus moving the water cutter 24. The vertical position adjustment is achieved. When the water cutter 24 is working, the water in the water tank 5 is drawn out by the water pump 21 through the hose. The water pump 21 delivers the water to the pressurized nozzle 22, which sprays the water out in a high-pressure form. This works in conjunction with the water cutter 24 to treat the surface of the stone. The cavity inside the positioning box 6, the chute in the middle of its upper end, and the multiple through grooves equidistantly opened on both sides of the chute are conducive to the discharge of wastewater and waste residue generated during the processing, keeping the processing environment clean and further improving the stability and precision of the processing. After processing, the stone can be removed.
