[0026] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0027] like Figures 1 to 3 As shown, an embodiment of the utility model provides a front chuck avoidance integrated guide rail structure of a laser tube cutting machine, including a frame 1, a laser cutting head 2, a front chuck 3, a first guide rail 41, a second guide rail 42, a rack 5, a movable frame 6 and a walking motor 7; a gantry 10 is provided at the front end of the frame 1, and the top of the gantry 10 is connected to the laser cutting head 2 through a dual-axis moving mechanism 8, and the laser cutting head 2 is used to emit a cutting laser beam downward; the dual-axis moving mechanism 8 can drive the laser cutting head 2 to move in the horizontal and vertical directions, and the laser cutting head 2 can realize fixed-length cutting of the tube through the laser beam.

[0028] A mounting platform 11 is provided on the frame 1 below the gantry 10, and the first guide rail 41 and the rack 5 are respectively arranged in parallel on both sides of the mounting platform 11, and the bottom of the movable frame 6 is connected to the first guide rail 41 through a first slider 411, and the walking motor 7 is arranged in the movable frame 6, and the output end of the walking motor 7 is set downward and is engaged with the rack 5 through a gear 51, and the walking motor 7 is used to drive the movable frame 6 to move along the length direction of the first guide rail 41, and the side wall of the movable frame 6 is provided with a mounting plate 61, and the second guide rail 42 is arranged on the side wall of the mounting platform 11, and the mounting plate 61 is connected to the second guide rail 42 through a second slider 421, and the front chuck 3 is arranged on the mounting plate 61, and the front chuck 3 is used to clamp the pipe to be cut, and the front chuck 3 can pass through the bottom of the gantry 10 as the movable frame 6 moves. By installing the front chuck 3 on the movable frame 6 and moving it along the length direction of the mounting table 11, the front chuck 3 can pass freely under the gantry 10. In conjunction with the laser cutting head 2, the pipe can be cut to a fixed length without moving the gantry 10, thereby reducing the positioning error of the laser cutting head 2 and improving the cutting accuracy; and setting the front chuck 3 as a mobile structure can reduce the space occupied by the equipment in the workshop and improve the installation flexibility of the equipment; adopting a double guide rail structure of the first guide rail 41 and the second guide rail 42 can effectively prevent the movable frame 6 from deflecting, shaking or swinging during movement, thereby improving the movement stability of the front chuck 3; it should be noted that the length of the first guide rail 41 and the second guide rail 42 are equal.

[0029] like Figure 1 and Figure 3 As shown, the sidewalls of the mounting platform 11 are further provided with a plurality of limit fixing plates 110 along their length. The limit fixing plates 110 are provided with proximity sensors 111. The mounting plate 61 is provided with a sensing plate 611. The sensing plate 611 is configured to sense and connect with the proximity sensor 111 when the mounting plate 61 is in proximity thereto. By providing the proximity sensors 111 on the sidewalls of the mounting platform 11 and cooperating with the sensing plates 611, the movement position of the front chuck 3 can be accurately detected. When the movable frame 6 moves to a predetermined limit position, the proximity sensors 111 sense and connect with the sensing plates 611, thereby controlling the travel motor 7 to stop and achieve automatic limit, thereby preventing the movement of the front chuck 3 from exceeding the set range.

[0030] like Figures 1 to 3As shown, a limit plate 612 is further provided on the mounting plate 61, and an anti-collision buffer block 12 is provided at the end of the frame 1. The limit plate 612 is located on the same horizontal line as the anti-collision buffer block 12. When the moving stroke of the movable frame 6 reaches the limit position, the limit plate 612 can abut against the anti-collision buffer block 12, thereby acting as a limit buffer to prevent damage to the equipment caused by sudden impact.

The transverse linear module 81 is arranged on the top of the gantry 10, and the movable end of the transverse linear module 81 is connected to the lifting linear module 82, and the movable end of the lifting linear module 82 is connected to the laser cutting head 2. The arrangement of the transverse linear module 81 and the lifting linear module 82 allows the laser cutting head 2 to move freely in the transverse and vertical directions to accommodate pipes of various sizes and shapes. For example, when the diameter of the pipe is large or small, the lifting linear module 82 can adjust the height of the laser cutting head 2 so that the focus of the laser beam is at the optimal cutting position; the transverse linear module 81 allows the laser cutting head 2 to move left and right, thereby quickly positioning to adapt to different cutting paths.

[0032] like Figure 3 As shown, further, the side wall of the gantry 10 is provided with an avoidance groove structure 101 for the front chuck 3 to pass through.

[0033] Furthermore, the travel motor 7 is a servo motor, which can improve the position movement accuracy of the front chuck 3, so that the cutting position of the laser cutting head 2 and the pipe is accurately aligned, thereby improving the cutting accuracy.

[0034] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
