Description

Technical Field

[0001] The invention relates to the technical field of gantry milling machines, in particular to a gantry milling machine with an air cooling mechanism. Background Art

[0002] A gantry milling machine is a large metal cutting machine tool, mainly used for processing large-sized and heavy workpieces. Its characteristic is that the tool can move in three dimensions in the horizontal and vertical directions. During processing, the workpiece is fixed on the workbench, and the tool cuts by moving. The main components of a gantry milling machine include a gantry, a crossbeam, a slide, a ram, a workbench and a spindle. The gantry consists of two columns and a crossbeam connecting the columns, providing stable support and rigidity; the crossbeam, also known as a transverse slide beam, connects the two columns and supports the slide and the ram; the slide is mounted on the crossbeam and can move laterally along the crossbeam; the ram is mounted on the slide and can move up and down to drive the tool or spindle for vertical processing; the workbench is used to fix the workpiece and can move longitudinally along the machine tool so that the workpiece can be cut at different positions; the spindle is the part that loads the tool, which rotates and drives the tool for cutting. The main features of a gantry milling machine include the ability to process large workpieces, suitability for multi-axis linkage, and high rigidity and stability. It is widely used in industries such as aviation, shipbuilding, automobiles and heavy machinery for precision processing of large and complex parts.

[0003] During the cutting process of the cutter head of a gantry milling machine, it is usually difficult for a fixed air-cooling system to effectively blow away the entangled debris, because during the cutting process, the debris will be entangled on the cutter head or the workpiece due to the rotation of the cutter head and the cutting force. Different entangled debris usually form resistance in different directions, and the fixed airflow is not enough to overcome this resistance, so it cannot be effectively blown away. In addition, the high-speed rotation and reciprocating motion of the cutter head during cutting cause the debris to change dynamically. The fixed air-cooling system cannot adapt to these changes, resulting in the airflow being unable to deal with the newly generated entangled debris in time. Therefore, it is difficult for a fixed air-cooling system to effectively remove the debris entangled on the cutter head. Summary of the invention

[0016] Preferably, the outer wall of the positioning plate is fixedly connected to the bottom of the connecting plate, and a through hole is provided on the surface of the connecting plate.

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides a gantry milling machine with an air cooling mechanism, which has the following features:

[0019] Beneficial effects:

[0020] 1. The gantry milling machine with air cooling mechanism uses a circumferential mechanism to allow the ejected air to rotate and blow toward the cutting head. The ejected air rotates and blows around the cutter head, which can effectively help remove the debris around the cutter head. The centrifugal force generated by the rotating airflow pushes the debris outward, thereby reducing the entanglement and obstruction of the debris to the cutter head. This design can ensure that the cutting area remains clean, improve cutting efficiency, and avoid the reduction of cutting quality due to debris accumulation.

[0021] 2. The gantry milling machine with air cooling mechanism utilizes a vertical mechanism setting. The connecting plate drives the guide rod to rotate, and under the action of spring 1, it tightly contacts the annular wave part, so that the connecting plate rotates and reciprocates up and down at the same time, and the vortex tube rotates and reciprocates up and down at the same time, so that the vortex tube can spray cold air at different heights and angles during the cutting process, thereby more effectively removing debris around the cutter head. This movement increases the dynamic changes of the airflow, so that the air can more comprehensively cover the cutter head and its surrounding area, ensuring that the airflow can quickly blow the debris wrapped around the cutter head away from the cutting area, further improving the cleanliness and efficiency of the cutting process, and reducing the risk of reduced cutting quality due to debris.

[0022] 3. In the gantry milling machine with air cooling mechanism, during the rotation of the moving square block, under the action of centrifugal force, the faster the speed of the driving motor is, the farther the moving square block, the output tube and the vortex tube are from the cutter head. At this time, the moving square block compresses the spring 2, and when the speed is low, it will return to its original position under the action of the spring 2, so that the injection range is larger. During the rotation of the moving square block, it is affected by the centrifugal force and moves away from the cutter head, resulting in an increase in the injection range of the output tube and the vortex tube. In this way, the ejected cold air can cover a wider area and effectively remove the debris around the cutter head. When the speed is high, the moving square block can actively adjust the injection range under the action of centrifugal force to ensure that the cold air can blow to every corner of the cutting area with a larger amplitude. When the speed is reduced, the recovery effect of the spring 2 reduces the injection range, which is convenient for centralized processing of the debris near the cutter head. Such a design can flexibly adjust the range and intensity of the cold air injection according to the changes in cutting conditions, thereby more effectively maintaining the cleanliness of the cutter head and ensuring the stability and accuracy of the cutting process.

[0023] 4. The gantry milling machine with air cooling mechanism utilizes the vortex tube setting, turns on the driving motor to drive the rotating shaft to rotate, and the rotating shaft drives the bottom cutter head to rotate and cut, and then inputs high-pressure air through the input pipe. The high-pressure air in the input pipe enters the vortex tube through the hollow connecting ring, the hollow fixed ring, the fixed tube one, the fixed sleeve one, the fixed square block, the fixed tube two, the fixed sleeve two, the movable square block, and the output pipe. The physical principle of high-pressure air outputting cold air through the vortex tube is based on fluid dynamics and thermodynamics. The high-pressure air in the vortex tube is introduced and rotated rapidly to form a vortex, so that the airflow is stratified, and the gas close to the tube wall heats up due to friction, while the gas in the center area maintains a lower temperature, forming a separation of cold air and hot air. The cold air is output from one end of the vortex tube, and the hot air is discharged from the other end, so that the cold air output end of the vortex tube is aligned with the cutting head for cooling. Compared with the traditional high-pressure air cooling system, the advantage of the cold air output end of the vortex tube for cooling the cutting head is that more efficient temperature control can be achieved. The vortex tube uses the principle of air flow rotation to effectively separate cold air and hot air, making the temperature of the cold air lower and more stable, and directly cooling the cutter head efficiently, improving the cooling effect.

[0024] 5. The gantry milling machine with air cooling mechanism uses a circumferential mechanism setting, and the vortex tube and the cutter head are relatively reversed. This reversing motion can enhance the impact force of the ejected cold air on the cutter head, thereby more effectively removing the entangled debris around the cutter head. When reversing, the airflow direction of the cold air is opposite to the cutting direction of the cutter head, thereby increasing the relative speed between the airflow and the debris. This relative motion helps to break the adhesion of the chips, making it easier to blow them off the surface of the cutter head and reducing obstructions during the cutting process. Secondly, by changing the spray angle and direction of the cold air, the entire cutting area of ​​the cutter head can be better covered, ensuring that the cold air flows to each part that needs cooling, further improving the cooling effect, and preventing heat accumulation from causing overheating of the tool. Finally, the reversing motion of the vortex tube can also improve the distribution of the airflow, allowing the cold air to be ejected more evenly, which is crucial to maintaining the stability of cutting performance in complex cutting environments.

During the rotation process of the mobile square block 94, under the action of centrifugal force, the faster the speed of the driving motor 6 is, the farther the mobile square block 94, the output tube 97 and the vortex tube 98 are away from the cutter head. At this time, the mobile square block 94 compresses the spring 2 95, and when the speed is low, it will return to its position under the action of the spring 2 95.

[0039] In summary, the gantry milling machine with air cooling mechanism starts the driving motor 6 to drive the rotating shaft 71 to rotate, the rotating shaft 71 drives the bottom cutter head to rotate and cut, and then inputs high-pressure air through the input pipe 78. The high-pressure air in the input pipe 78 passes through the hollow connecting ring 77, the hollow fixed ring 76, the fixed pipe 1 82, the fixed sleeve 1 83, the fixed square block 91, the fixed pipe 2 92, the fixed sleeve 2 93, the mobile square block 94, and the output pipe 97 to enter the vortex tube 98. The physical principle of high-pressure air outputting cold air through the vortex tube 98 is based on the fluid Dynamics and thermodynamics, the high-pressure air in the vortex tube 98 is introduced and rotated rapidly, forming a vortex, which stratifies the airflow. The gas near the tube wall heats up due to friction, while the gas in the center area maintains a lower temperature, forming a separation of cold air and hot air. The cold air is output from one end of the vortex tube 98, and the hot air is discharged from the other end, so that the cold air output end of the vortex tube 98 is aimed at the cutting head for cooling. Compared with the traditional high-pressure air cooling system, the advantage of the cold air output end of the vortex tube 98 for cooling the cutting head is that it can achieve more efficient temperature control. The vortex tube 98 uses the principle of airflow rotation to effectively separate cold air and hot air, making the temperature of the cold air lower and more stable, and directly cooling the head efficiently, improving the cooling effect.

[0040] At this time, the rotating shaft 71 drives the central gear 72 to rotate, the central gear 72 drives the planetary gears 73 to reverse, the planetary gears 73 drives the outer gear ring 75 to reverse, the outer gear ring 75 drives the hollow fixed ring 76 to reverse, the hollow fixed ring 76 drives the fixed tube 1 82, the fixed sleeve 1 83, the connecting plate 85, the fixed square block 91, the fixed tube 2 92, the fixed sleeve 2 93, the movable square block 94, the output tube 97 and the vortex tube 98 to rotate, so that the air ejected from the vortex tube 98 rotates and blows toward the cutting bit. The ejected air rotates and blows in a manner surrounding the cutter head, which can effectively help clear the debris around the cutter head. The centrifugal force generated by the rotating airflow pushes the debris outward, thereby reducing the entanglement and obstruction of the debris to the cutter head. This design can ensure that the cutting area remains clean, improve cutting efficiency, and avoid the reduction of cutting quality due to accumulation of debris.

[0041] And the vortex tube 98 is relatively reversed with the cutter head, and the design of the vortex tube 98 being relatively reversed with the cutter head has multiple advantages. First, this reverse motion can enhance the impact force of the ejected cold air on the cutter head, thereby more effectively removing the entangled debris around the cutter head. When reversed, the airflow direction of the cold air is opposite to the cutting direction of the cutter head, thereby increasing the relative speed between the airflow and the debris. This relative motion helps to break the adhesion of the debris, making it easier to be blown off the surface of the cutter head and reducing the obstruction during the cutting process. Secondly, by changing the spray angle and direction of the cold air, the entire cutting area of ​​the cutter head can be better covered, ensuring that the cold air flows to each part that needs to be cooled, further improving the cooling effect, and preventing the tool from overheating due to heat accumulation. Finally, the reverse motion of the vortex tube 98 can also improve the distribution of the airflow, so that the cold air can be ejected more evenly, which is crucial to maintaining the stability of the cutting performance in a complex cutting environment. In short, the relative reversal design of the vortex tube 98 and the cutter head effectively enhances the cleaning and cooling capabilities of the cold air, thereby improving the cutting efficiency and service life of the cutter head.

[0042] The connecting plate 85 drives the guide rod 86 to rotate, and under the action of the spring 84, it tightly contacts the annular wave member 81, so that the connecting plate 85 rotates and reciprocates up and down at the same time, and the vortex tube 98 rotates and reciprocates up and down at the same time, so that the vortex tube 98 can spray cold air at different heights and angles during the cutting process, thereby more effectively removing debris around the cutter head. This movement increases the dynamic changes of the airflow, allowing the air to more comprehensively cover the cutter head and its surrounding area, ensuring that the airflow can quickly blow the debris wrapped around the cutter head away from the cutting area, further improving the cleanliness and efficiency of the cutting process, and reducing the risk of reduced cutting quality due to debris.

[0043] During the rotation of the moving square block 94, under the action of centrifugal force, the faster the speed of the driving motor 6 is, the farther the moving square block 94, the output tube 97 and the vortex tube 98 are from the cutter head. At this time, the moving square block 94 compresses the spring 2 95, and when the speed is low, it will return to its original position under the action of the spring 2 95, so that the injection range is larger. During the rotation of the moving square block 94, the centrifugal force affects the moving square block 94 and moves away from the cutter head, resulting in an increase in the injection range of the output tube 97 and the vortex tube 98. In this way, the ejected cold air can cover a wider area and effectively remove the debris around the cutter head. When the speed is high, the moving square block 94 can actively adjust the injection range under the action of centrifugal force to ensure that the cold air can be blown to every corner of the cutting area with a larger amplitude. When the speed is reduced, the recovery effect of the spring 2 95 reduces the injection range, which is convenient for centralized processing of the debris near the cutter head. Such a design can flexibly adjust the range and intensity of the cold air injection according to the changes in the cutting conditions, so as to more effectively maintain the cleanliness of the cutter head and ensure the stability and accuracy of the cutting process.

[0044] The principle of the vortex tube 98 ejecting cold air: First, high-pressure air enters the vortex tube 98 through the input pipe 78, and the input high-pressure gas has high kinetic energy. After entering the vortex tube 98, the high-pressure air is forced to rotate along the inner wall of the vortex tube 98, forming a high-speed vortex. This rotational motion is achieved through a specific design inside the vortex tube 98, usually a spiral channel or a specific structure that causes the airflow to rotate. In the vortex tube 98, the rotation of the airflow causes the gas to be stratified, and the temperature of the gas close to the tube wall increases due to friction with the tube wall, while the gas in the center area maintains a lower temperature. This is because the friction of the tube wall causes the gas energy in the boundary layer to be transferred to the tube wall, thereby increasing the temperature, while the gas in the center area maintains a lower temperature because it is far away from the heat source. Due to the rotation and stratification effect of the airflow, the gas in the vortex tube 98 is effectively divided into two parts: cold air and hot air. The cold air is output from one end of the vortex tube 98 (usually the outlet end), while the hot air is discharged from the other end (usually the exhaust end). Finally, the cold air is ejected from the outlet of the vortex tube 98 and can be used to cool the cutting bit or other equipment. Due to its low temperature, this cold air can effectively reduce the temperature of the cutting bit and its surrounding environment, reduce heat accumulation, and improve cutting performance. Through this principle, the vortex tube 98 can achieve efficient cooling without moving parts and refrigerants, and is widely used in various industrial fields, especially in cutting and processing processes that require precise temperature control.
