[0002] CNC gantry milling machine is a kind of high-efficiency and high-precision machining equipment, which is widely used in the machining and manufacturing of various large workpieces. The working principle of CNC gantry milling machine is based on the programming control of CNC system. The operator first uses CAD / CAM software to perform three-dimensional modeling of the workpiece and planning of the machining path, and then inputs the generated machining program into the CNC system. According to the instructions in the machining program, the CNC system controls the various moving parts of the machine tool to perform cutting according to the predetermined path and speed. During the machining process, the electrical control system monitors and adjusts the motion state of the machine tool in real time to ensure machining accuracy and stability.

DETAILED DESCRIPTION

[0022] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] See also Figures 1 to 5 As shown, the utility model provides an airflow tool cooling CNC fixed-beam gantry milling machine, comprising a bed 1 and a gantry 2, the gantry 2 being movably arranged on the bed 1, the bed 1 being provided with a first driving component for driving the gantry 2 to move along the bed 1, a screw slide 3 being movably arranged on the inner side of the gantry 2, the gantry 2 being provided with a second driving component for driving the screw slide 3 to move laterally, a moving plate 4 being provided at the working end of the screw slide 3, a tool body 5 being installed on one side of the moving plate 4, a cooling component 6 for cooling the tool body 5 being further provided on the moving plate 4, and dust suction components 7 for collecting debris generated during machining are provided on both sides of the gantry 2.

[0024] By starting the first driving component, the first driving component drives the gantry 2 to move along the bed 1. The gantry 2 moves precisely in the X-axis direction so that the tool body 5 can reach the predetermined processing position. When the gantry 2 reaches the predetermined position, the second driving component starts to work and drives the screw slide 3 to move laterally. The screw slide 3 moves precisely in the Y-axis direction to further adjust the position of the tool body 5 to ensure the precise alignment between the tool body 5 and the workpiece. When the tool body 5 reaches the precise position, the cutting process begins. During the cutting process, the cooling component 6 continues to cool the tool body 5 to prevent the tool body 5 from being damaged by the high temperature generated during the cutting process. While the cutting process is being performed, the dust collection component 7 continues to work to collect the debris generated during the processing, thereby keeping the working environment clean, helping to reduce the interference of debris on the processing process, and improving the processing efficiency and quality.

[0025] See also Figures 1 to 4 As shown, the dust collection assembly 7 includes a dust collection box 71 and an exhaust fan 72; the dust collection box 71 is arranged on both sides of the gantry 2, and the exhaust fan 72 is arranged on the top of the dust collection box 71, and the working end of the exhaust fan 72 is connected to the dust collection box 71, and a filter screen 73 is arranged in the dust collection box 71, and a quick-release component for facilitating the replacement of the filter screen 73 is arranged between the filter screen 73 and the dust collection box 71, and an air suction pipe 74 is arranged on one side of the dust collection box 71, and one end of the air suction pipe 74 is connected to an air suction head 75, and the air suction head 75 is movably arranged on the bed 1, and an adjusting component for driving the air suction head 75 to move is arranged on the bed 1, and a collecting box 76 is slidably arranged at the bottom of the filter screen 73 in the dust collection box 71.

[0026] During cutting, by starting the exhaust fan 72, the exhaust fan 72 generates suction to suck the debris generated during the processing into the suction pipe 74 through the suction head 75, and then suck it into the dust box 71 through the suction pipe 74. The sucked debris is trapped on the filter 73, and the filtered debris falls into the collection box 76 under the action of gravity, thereby keeping the working environment clean and helping to reduce the interference of debris on the processing process. When the filter 73 is blocked or needs to be cleaned, the operator can quickly disassemble the filter 73 through the quick-release parts for replacement or cleaning. This helps to ensure the efficiency of dust collection and avoid affecting the dust collection effect due to the blockage of the filter 73.

[0027] See also Figure 4As shown, the quick-release parts include a mounting plate 77 and a fixing plate 78; the mounting plate 77 is arranged on one side of the filter screen 73; the fixing plate 78 is arranged on the side of the dust box 71 away from the gantry 2; two groups of light rods 79 are symmetrically arranged on the top of the fixing plate 78, one end of the light rods 79 is provided with a limiting disk 710, and sliding plates 711 are slidably arranged on the two groups of light rods 79, and a first spring 712 is also sleeved on the light rods 79, one end of the first spring 712 abuts against the top of the sliding plate 711, and the other end of the first spring 712 abuts against the bottom of the limiting disk 710, a pull handle 714 is arranged on the top of the sliding plate 711, and a plug plate 713 is arranged at the bottom of the sliding plate 711, one end of the plug plate 713 is provided with an abutting portion, and a plug groove that can be plugged and matched with the abutting portion is provided on the mounting plate 77.

[0028] When the filter 73 needs to be removed, the operator first pulls the handle 714, and the handle 714 drives the sliding plate 711 to move upward. The movement of the sliding plate 711 will compress the first spring 712 and make the plug plate 713 fall out of the plug slot. At this time, the filter 73 and the mounting plate 77 can be removed from the dust box 71 for replacement or cleaning. When it is necessary to install, by pulling the handle 714, the handle 714 drives the sliding plate 711 to move upward and compress the first spring 712. At this time, the filter 73 is inserted into the dust box 71. Subsequently, by loosening the handle 714, under the action of the reset force of the first spring 712, the sliding plate 711 drives the plug plate 713 to move downward until the abutment portion is fully inserted into the plug slot, thereby fixing the filter 73.

[0029] See also Figure 3 As shown, the adjusting component includes a third threaded rod 715; the third threaded rod 715 is threadedly connected to one side of the gantry 2 in a horizontal state, a turntable 716 is provided at one end of the third threaded rod 715, and an arc block 717 is provided at the other end of the third threaded rod 715, the arc block 717 is connected to the suction head 75, and a limit rod 718 is provided at the bottom of the third threaded rod 715 on one side of the arc block 717, and a through hole for the limit rod 718 to move is opened on one side of the gantry 2.

[0030] When the position of the suction head 75 needs to be adjusted, the operator first rotates the turntable 716, and the rotation of the turntable 716 drives the third threaded rod 715 to rotate. The rotation of the third threaded rod 715 drives the arc block 717 to move, and as the arc block 717 moves, the suction head 75 also moves accordingly, thereby achieving the purpose of adjusting the position, which helps the operator to flexibly adjust the dust collection position according to processing requirements and improve the dust collection efficiency and quality.

[0031] See also Figure 5As shown, the cooling component 6 includes an extension plate 61 and a centrifugal fan 62; the extension plate 61 is arranged on one side of the movable plate 4 and is located at the top of the tool body 5; the centrifugal fan 62 is arranged on the top of the extension plate 61, and the bottom of the extension plate 61 is connected to an airflow pipe 63, and a mounting ring 64 is arranged on the movable plate 4 and is located on one side of the tool body 5, and an airflow nozzle 65 is arranged in the mounting ring 64, and the top of the airflow nozzle 65 is connected to one end of the airflow pipe 63.

[0032] When cooling is required, the operator starts the centrifugal fan 62. The centrifugal fan 62 starts to rotate, generating a high-speed airflow. The generated high-speed airflow is transported to the airflow nozzle 65 through the airflow pipe 63 at the bottom of the extension plate 61. The airflow is sprayed onto the tool body 5 through the airflow nozzle 65. The airflow sprayed onto the tool body 5 can take away the heat generated by the tool body 5 during the processing, reduce the temperature of the tool, thereby helping to reduce the thermal deformation and wear of the tool body 5, and ensure the stability and durability of the tool body 5 during the processing.

[0033] See also Figure 2 As shown, the first driving component includes a first threaded rod 21; the first threaded rod 21 is arranged at the bottom of the bed 1, and a first motor 22 is arranged on one side of the bed 1, and the output end of the first motor 22 is connected to one end of the first threaded rod 21, and a moving block 23 is threadedly connected to the first threaded rod 21, and the top of the moving block 23 is connected to the bottom of the gantry 2, and sliding rods 24 are arranged on both sides of the bed 1, and a first sliding block 25 is slidably arranged on the sliding rod 24, and the first sliding block 25 is connected to the bottom of the gantry 2.

[0034] When the position of the gantry 2 needs to be adjusted, the first motor 22 is started. The first motor 22 drives the first threaded rod 21 to rotate. Since the rotation of the first threaded rod 21 drives the moving block 23 to move, the movement of the moving block 23 drives the gantry 2 to move. When the gantry 2 moves, the movement of the gantry 2 drives the first slider 25 to slide on the slide rod 24, thereby ensuring the stability of the movement of the gantry 2.

[0035] See also Figure 1 As shown, the second driving component includes a second threaded rod 26; the second threaded rod 26 is horizontally arranged on the inner side of the gantry 2, and a second motor 27 is arranged on one side of the gantry 2, and the output end of the second motor 27 is connected to one end of the second threaded rod 26, and a driving block 28 is threadedly connected to the second threaded rod 26, and one side of the driving block 28 is connected to the screw slide 3, and second sliders 29 are arranged on the top and bottom of the driving block 28 on the screw slide 3, and a slide rail 210 for the second slider 29 to move is arranged on the gantry 2.

[0036] When the position of the screw slide 3 needs to be adjusted, the operator starts the second motor 27, and the second motor 27 drives the second threaded rod 26 to rotate. The rotation of the second threaded rod 26 drives the driving block 28 to move, and the movement of the driving block 28 drives the screw slide 3 to move.

[0037] By starting the first driving component, the first driving component drives the gantry 2 to move along the bed 1. The gantry 2 moves precisely in the X-axis direction so that the tool body 5 can reach the predetermined processing position. When the gantry 2 reaches the predetermined position, the second driving component starts to work and drives the screw slide 3 to move horizontally. The screw slide 3 moves precisely in the Y-axis direction to further adjust the position of the tool body 5 to ensure the precise alignment between the tool body 5 and the workpiece. When the tool body 5 reaches the precise position, the cutting process begins. During the cutting process, the operator starts the centrifugal fan 62. The centrifugal fan 62 starts to rotate and generates a high-speed airflow. The generated high-speed airflow is transported to the airflow nozzle 65 through the airflow pipe 63 at the bottom of the extension plate 61. The airflow is sprayed onto the tool body 5 through the airflow nozzle 65. The airflow sprayed onto the tool body 5 can take away the heat generated by the tool body 5 during the processing process, reduce the temperature of the tool, thereby helping to reduce the thermal deformation and wear of the tool body 5, and ensure the stability and durability of the tool body 5 during the processing process. During the cutting process, the exhaust fan 72 is started. The exhaust fan 72 generates suction to suck the debris generated during the processing into the suction pipe 74 through the suction head 75, and then sucked into the dust box 71 through the suction pipe 74. The sucked debris is trapped on the filter 73, and the filtered debris falls into the collection box 76 under the action of gravity, thereby keeping the working environment clean and helping to reduce the interference of debris on the processing process. When the filter 73 is blocked or needs to be cleaned, the operator can quickly disassemble the filter 73 through the quick-release parts for replacement or cleaning. This helps to ensure the efficiency of dust collection and avoid the dust collection effect being affected by the blockage of the filter 73, thereby collecting the debris generated during the processing, keeping the working environment clean, helping to reduce the interference of debris on the processing process, and improving the processing efficiency and quality.
