[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, a cantilever CNC cutting machine comprises a cutting machine gantry 1, a plasma cutting head 2 is fixedly connected to the bottom of the cutting machine gantry 1, a blocking mechanism 3 is arranged on the outer side of the plasma cutting head 2, the blocking mechanism 3 comprises a baffle 4, the inner side of the baffle 4 is movably connected to the outer side of the plasma cutting head 2 near the middle, the bottom of the baffle 4 is fixedly connected to a sleeve 5, the inner top of the sleeve 5 is meshingly connected to the middle of the outer side of the plasma cutting head 2 near the bottom of the baffle 4, the outer side of the sleeve 5 is movably connected to a sleeve 6, guide columns 8 are symmetrically arranged on both sides of the top of the sleeve 6, the outer side of the guide column 8 is movably connected to a spring 12, the bottom of the spring 12 is movably connected to the top of the sleeve 6 near the edge, the top of the spring 12 is movably connected to the upper part of the baffle 4 near the outer side, the inner side of the sleeve 6 near the bottom is fixedly connected to a bearing 10, and the top of the bearing 10 is fixedly connected to an impeller 9.

[0022] In this embodiment, the bottom of the sliding sleeve 6 is fixedly connected to a limit ring 7 , and the bottom of the limit ring 7 is movably connected to a plurality of balls 11 .

[0023] When the limiting ring 7 moves, it can drive the ball 11 to move together, and the ball 11 rolls while moving, thereby avoiding scratching the surface of the workpiece.

[0024] In this embodiment, the inner diameter of the limiting ring 7 matches the outer diameter of the sliding sleeve 6 , and a plurality of circular grooves are formed at the bottom of the limiting ring 7 .

[0025] The circular groove of the limiting ring 7 can accommodate the movement of the ball 11 inside, and the diameter of the bottom of the circular groove is smaller than the diameter of the ball 11, so that the ball 11 will not fall off.

[0026] In this embodiment, the baffle 4 has a circular ring shape, and circular holes are symmetrically opened on both sides of the top of the baffle 4.

[0027] The baffle plate 4 can provide a support point for the spring 12 and can cooperate with the guide column 8 to limit the freedom of movement of the sliding sleeve 6 .

[0028] In this embodiment, the bottom of the impeller 9 is annular, and a plurality of blades are evenly arranged on the top of the annular shape.

[0029] When the impeller 9 is pushed by the heat dissipation airflow discharged from the plasma cutting head 2, it will rotate and block the sputtering generated when cutting the workpiece through the blades.

[0030] In this embodiment, a plurality of heat dissipation slots are provided on the top of the plasma cutting head 2, a thread is provided on the outer side of the plasma cutting head 2 near the middle, and a thread is provided on the inner side of the sleeve 5 near the upper part.

[0031] The sleeve 5 can be fixed to the outside of the plasma cutting head 2 by being engaged with the thread of the plasma cutting head 2, so that the blocking mechanism 3 is fixed.

[0032] In this embodiment, circles are provided at the top and bottom of the inner side of the sliding sleeve 6 , a plurality of long grooves are provided at the outer side of the sliding sleeve 6 , and a retaining ring is provided at the bottom of the sleeve 5 .

[0033] The sleeve 5 can limit the movement range of the sliding sleeve 6 through the retaining ring, and the long groove of the sliding sleeve 6 can allow air flow to pass through.

[0034] It should be noted that the utility model is a cantilever CNC cutting machine, which can prevent the sputtering generated on the top of the workpiece when the plasma cuts the workpiece, and make the CNC cutting machine more environmentally friendly, while reducing the contamination of the workpiece surface by the sputtering. By setting the ball 11, it can prevent the blocking mechanism 3 from scratching the workpiece surface during operation;

[0035] The specific implementation method is to connect the air source to make the compressed air pass through the air groove of the plasma cutting head 2. After passing through the air groove, the compressed air is discharged through the long groove and the bottom of the sliding sleeve 6. The compressed air cools down the plasma cutting head 2 when passing through it, and the compressed air will push the blades to rotate when passing through the impeller 9. The impeller 9 is constrained by the bearing 10 and can only rotate in the original position. By controlling the plasma cutting head 2 to move downward, the bottom of the plasma cutting head 2 is in contact with the upper surface of the workpiece and cutting is performed. Since the bottom of the ball 11 is lower than the bottom of the plasma cutting head 2;

[0036] The ball 11 will first contact the workpiece, and then stop moving after contacting the workpiece, and stop the limit ring 7 as well. At this time, the plasma cutting head 2 will continue to move downward, and will drive the sleeve 5 to move together. The sleeve 5 will move while driving the baffle 4 to move together. The baffle 4 will squeeze the spring 12 to contract and store force. The spring 12 will push the sleeve 6 downward. The sleeve 6 will apply force to the ball 11 through the limit ring 7, so that the ball 11 keeps in contact with the surface of the workpiece. After the plasma cutting head 2 contacts the workpiece, an arc is generated, and the workpiece can be cut by moving the plasma cutting head 2 along the direction;

[0037] During the movement of the plasma cutting head 2, the ball 11 contacts the workpiece and rolls while moving, so that no scratches are generated on the surface of the workpiece, thereby ensuring the appearance quality of the workpiece. When the workpiece is cut, high-temperature sputtering will be generated and sputtered toward the top of the workpiece. During the upward movement of the sputtering, it will be blocked by the rotating impeller 9, so that the sputtering is filtered and cooled. At the same time, the sputtering can be intercepted for the second time by the sleeve 6, reducing the splashing of sputtering and affecting the quality of the equipment and workpiece, ensuring the processing quality and cleanliness of the CNC cutting machine, and improving safety.

[0038] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
