Description

Technical Field

[0001] This utility model relates to the technical field of pipe cutting devices, specifically a movable gantry pipe cutting device. Background Technology

[0002] In modern industrial production, laser tube cutting technology is widely used due to its high efficiency and precision. However, when cutting a whole tube, the portion of the tube extending out of the chuck is affected by gravity and its own deformation, which can easily affect the cutting accuracy during laser cutting.

[0003] Currently, most pipe laser cutting machines on the market integrate the front chuck and the laser together, which leads to the problems mentioned above. Therefore, in order to overcome the above technical problems, to handle the cutting of ordinary pipes, and to prevent the impact of gravity and deformation on the pipe itself during the cutting of longer pipes, thus reducing the cutting accuracy, a movable gantry pipe cutting device is proposed to overcome the above technical problems and improve the cutting accuracy. Utility Model Content

A Y-axis guide rail and a Y-axis rack are mounted on the upper end face of the device body. A Y-axis slider is mounted on the surface of the Y-axis guide rail, and a movable cutting device is mounted on the surface of the Y-axis slider. The movable cutting device includes an X-axis moving structure, a Y-axis moving structure, a Z-axis moving structure, and a cutting structure. The movable rear chuck and the fixed front chuck hold the pipe material. The cutting area of ​​the movable cutting device on the pipe material is the distance between the movable rear chuck and the fixed front chuck. The X-axis moving structure is mounted on the surface of the Y-axis slider and connected to the X-axis moving structure. The Z-axis moving structure is connected to the Y-axis moving structure, and the cutting structure is connected to the Z-axis moving structure. The cutting structure allows adjustment of the pipe cutting position via the X, Y, and Z-axis moving structures.

[0006] Furthermore, the Y-axis moving structure includes a gantry, a Y-axis motor mounting base, and a motor. The gantry is connected to the Y-axis slider. A Y-axis motor mounting base is installed on the outer side of the gantry. A motor is installed on the surface of the Y-axis motor mounting base. A gear is connected to the output end of the motor and passes through the Y-axis motor mounting base to form a gear connection with the Y-axis rack. An X-axis moving structure is installed on the upper surface of the gantry.

[0007] Furthermore, the X-axis moving structure includes an X-axis slide plate, an X-axis guide rail, an X-axis rack, an X-axis slider, and an X-axis motor drive; both the X-axis guide rail and the X-axis rack are mounted on the upper end face of the gantry frame, one set of X-axis guide rails is mounted on the right side face of the gantry frame, an X-axis slider is mounted on the upper end face of the X-axis guide rail, an X-axis slide plate is connected to the surface of the X-axis slider, an X-axis motor drive is mounted on the upper end face of the X-axis slide plate, the output end of the X-axis motor drive is connected to a gear and meshes with the X-axis rack for transmission, and a Z-axis moving structure is mounted on the X-axis slide plate.

[0013] 1. If cutting pipes of normal length, such as Figure 5 As shown, the mobile cutting device overlaps with the fixed front chuck. When cutting a long pipe, such as... Figure 6As shown, the movable cutting structure begins to move to the left, extending its cutting area over the pipe. This allows the movable rear chuck and the fixed front chuck to clamp the pipe, providing good clamping and support during cutting. This prevents the pipe from becoming less accurate due to its weight, which is a problem when the pipe is long. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] Please see Figure 1-7 This utility model provides the following technical solution: a movable gantry pipe cutting device, comprising a device body 24, a movable rear chuck 17 movably mounted on the upper surface of the device body 24, and a fixed front chuck 16 fixedly mounted on the upper surface of the device body 24. A Y-axis guide rail 3 and a Y-axis rack 5 are located on the upper surface of the device body 24. A Y-axis slider 2 is mounted on the surface of the Y-axis guide rail 3, and a movable cutting device is mounted on the surface of the Y-axis slider 2. The movable cutting device includes an X-axis moving structure, a Y-axis moving structure, and a Z-axis moving structure. The device includes a cutting structure; the movable rear chuck 17 and the fixed front chuck 16 hold the pipe 23; the cutting area of ​​the movable cutting device for the pipe 23 is the distance between the movable rear chuck 17 and the fixed front chuck 16; the X-axis moving structure is installed on the surface of the Y-axis slider 2; the Y-axis moving structure is connected to the X-axis moving structure; the Z-axis moving structure is connected to the Y-axis moving structure; and the cutting structure is connected to the Z-axis moving structure. The cutting structure can adjust the cutting position of the pipe 23 through the X, Y, and Z-axis moving structures.

[0025] In this implementation plan, the specific working principle is as follows: When this device cuts pipes, for example, when cutting pipes of ordinary length... Figure 5 As shown, the movable cutting device overlaps with the fixed front chuck 16. However, it should be noted that the movable cutting device and the fixed front chuck 16 are not an integral structure. Once the movable cutting device moves to the fixed chuck 16, it can cut the pipe. However, when the pipe is long, the movable cutting device... (See reference...) Figure 6 As can be seen, the movable cutting device moves to the left, increasing the cutting area of ​​the pipe. This allows the movable rear chuck 17 and the fixed front chuck 16 to clamp the pipe, providing good clamping and support during cutting. This prevents the pipe from becoming less accurate due to its weight, which is a problem when the pipe is long.

[0026] Based on the above, the Y-axis moving structure in the movable cutting structure can be found in [reference needed]. Figure 5 and Figure 7As can be seen, the Y-axis moving structure includes a gantry 1, a Y-axis motor mounting base 4, and a motor. The gantry 1 is connected to the Y-axis slider 2. The Y-axis motor mounting base 4 is installed on the outer side of the gantry 1. The motor is mounted on the surface of the Y-axis motor mounting base 4. The output end of the motor is connected to a gear and passes through the Y-axis motor mounting base 4 to form a gear connection with the Y-axis rack 5. The X-axis moving structure is installed on the upper surface of the gantry 1. The motor drives the gear to rotate, thereby realizing the movement of the gantry 1 in the Y-axis direction through the meshing transmission relationship with the Y-axis rack 5, and thus driving the movement in the X-axis direction.

[0027] Based on the above, the details of the X-axis movement structure can be found in [reference needed]. Figure 4 and Figure 7 As can be seen, the X-axis moving structure includes an X-axis slide plate 6, an X-axis guide rail 7, an X-axis rack 8, an X-axis slider 9, and an X-axis motor drive 10. The X-axis guide rail 7 and the X-axis rack 8 are both installed on the upper end face of the gantry frame 1. One set of X-axis guide rails 7 is installed on the right side of the gantry frame 1. The X-axis slider 9 is installed on the upper end face of the X-axis guide rail 7. The X-axis slide plate 6 is connected to the surface of the X-axis slider 9. The X-axis motor drive 10 is installed on the upper end face of the X-axis slide plate 6. The output end of the X-axis motor drive 10 is connected to a gear and meshes with the X-axis rack 8 for transmission. The Z-axis moving structure is installed on the X-axis slide plate 6. The gear is driven to rotate by the X-axis motor drive 10, thereby driving the Z-axis moving structure to move through the meshing relationship with the X-axis rack 8.

[0028] Based on the above, the Z-axis movement structure can be found in the following document. Figure 4 and Figure 7 As can be seen, the Z-axis moving structure includes a moving frame, a Z-axis slider 11, a Z-axis guide rail 13, a Z-axis rack 14, and a Z-axis motor drive 15. The Z-axis guide rail 13 and the Z-axis rack 14 are both mounted on the surface of the moving frame. The Z-axis slider 11 is fixedly mounted on the right side of the X-axis slide plate 6 and connected to the Z-axis guide rail 13. The surface of the X-axis slide plate 6 is also equipped with a Z-axis motor drive 15, the output end of which is connected to a gear that meshes with the Z-axis rack 14 for transmission. A cutting structure is mounted on the moving frame. The Z-axis motor drive 15 drives the gear to rotate, thereby achieving meshing transmission through the Z-axis rack 14 and driving the cutting structure to adjust in the Z-axis direction.

[0029] For details regarding the cutting structure, please refer to the above. Figure 4 As can be seen, the cutting structure includes a laser 12, which is mounted on the right side of the moving frame.

[0030] In the Z-axis movement structure, when the avoidance action is executed, please refer to [the relevant documentation]. Figure 4As can be seen, a Z-axis limiting plate 22 is also installed on the right side of the X-axis slide plate 6, and a Z-axis limiting switch 21 is installed on the surface of the moving frame. When the laser 12 moves upward, if the Z-axis limiting switch 21 is triggered by the Z-axis limiting plate 22, the laser 12 stops moving along the Z-axis, which means that the laser 12 has completed the avoidance along the Z-axis.

[0031] The upper end face of the gantry frame 1 is equipped with an inner X-axis obstacle avoidance limit switch 19 and an outer X-axis obstacle avoidance limit switch 18. The lower end face of the X-axis slide plate 6 is equipped with an X-axis limit block 20. When the laser 12 moves to the X-axis limit block 20 and triggers the outer X-axis obstacle avoidance limit switch 18 but does not trigger the inner X-axis obstacle avoidance limit switch 19, the laser 12 stops moving along the X-axis, indicating that the laser assembly 12 has completed obstacle avoidance along the X-axis.

[0032] After the laser assembly 12 has completed the avoidance action along the X and Z axes, the avoidance action is completed. Subsequently, the Y-axis drive motor assembly 4, through the drive connecting gear, meshes with the Y-axis rack assembly 5 to drive the device to the processing position between the fixed front chuck 16 and the movable rear chuck 17 to cut the pipe according to the predetermined program.

[0033] After the entire tube is cut, the laser assembly 12 repeats the avoidance action. After the avoidance is completed, the Y-axis drive motor assembly 4 reverses the drive to move the device to the regular cutting position for the next processing.

[0034] It should be noted that the X-axis motor drive assembly 10 of the skateboard is connected to a gear, which meshes with the X-axis rack assembly 8 to drive the X-axis skateboard 6 along the guide rail direction for effective cutting and obstacle avoidance operations. The top of the gantry 1 is also equipped with an outer X-axis obstacle avoidance limit switch 18 and an inner X-axis obstacle avoidance limit switch 19, which cooperate with the X-axis limit block 20 installed at the bottom of the laser assembly 17 to restrict the movement of the X-axis skateboard 6 along the X-axis.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
