Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality" means two or more, unless otherwise specifically defined.

[0065] Please refer to Figure 1 and Figure 2 to describe the cutting device provided by the embodiment of the present application. The cutting device provided by the embodiment of the present application includes a support assembly 10, a rotating assembly 40, and a laser cutting assembly 50.

[0066] The rotating assembly 40 can rotate around the first axis X and can move along the first axis X direction. The rotating assembly 40 can be installed on a traveling frame, and the traveling frame drives the rotating assembly to move along the first axis X direction. The rotating assembly 40 can rotate around the first axis X on the traveling frame.

[0067] The support assembly 10 is used to support the pipe 80, and the axis of the pipe 80 coincides with the first axis X. The support assembly 10 supports the pipe to make part of the pipe 80 suspended and the axis of the pipe 80 coincides with the first axis X for convenient processing. Among them, the first axis X is the rotation axis when the designed laser cutting assembly 50 performs cutting rotation. During cutting, the pipe 80 needs to be placed so that the axis of the pipe 80 coincides with the first axis X.

[0068] The laser cutting assembly 50 is arranged on the rotating assembly 40. The laser cutting assembly 50 is used to emit laser to cut the pipe 80. Thus, the rotating assembly 40 can drive the laser cutting assembly 50 to rotate and move together, and then cut the pipe 80.

[0069] Based on the above structure, the support assembly supports the pipe to make part of it suspended and the axis of the pipe coincides with the first axis for convenient processing. After the pipe is supported on the support assembly, the rotating assembly drives the laser cutting assembly to move along the first axis to the designated position of the pipe. After the position is determined, the laser cutting assembly can be started to emit laser to cut the pipe. During cutting, the rotating assembly drives the laser cutting assembly to rotate around the first axis, so that the entire circumference of the pipe can be cut.

[0070] Specifically, the support assembly 10 includes at least two support frames 11. The support frames 11 are arranged at intervals along the first axis X in sequence. The height of the support frames 11 is adjustable so that the axis of the pipe 80 supported on each support frame 11 coincides with the first axis X. There are at least two support frames 11. After the at least two support frames 11 support the pipe 80, part of the pipe 80 is suspended, which enables the laser cutting assembly 50 to rotate around the pipe 80 to process the entire circumference of the pipe 80.

[0071] Since the support frames 11 are arranged at intervals along the first axis X, after the pipe 80 is placed on each support frame 11, its axial direction can be arranged to be parallel to the first axis X. Since pipes 80 of different types have different diameters, and when the pipe 80 is placed on the support frame 11, the diameter of the pipe 80 will affect the height of its axis. To address this issue, the support frame 11 is set to be height-adjustable, so that the height of the axis of the pipe 80 can be adjusted by adjusting the height of the support frame 11, enabling the axes of different pipes 80 to be adjusted to coincide with the first axis X.

[0072] It can be understood that since the pipe 80 is large in size and heavy in weight, when the pipe 80 is carried and placed on each support frame 11, during the carrying process, one end of the pipe 80 can be first placed on the outermost support frame 11, and then the pipe 80 can be pushed along the direction of the first axis X, continuously pushing the pipe 80 onto each support frame 11. Preferably, to facilitate the pushing of the pipe 80 to move along the first axis X on the support frame 11, rolling members 113 can be provided on the support frame 11, and the pipe 80 can be transported and conveyed in a rolling manner. The specific solution will be detailed below.

[0073] Refer to Figure 1 , the number of support frames can be two, three, four, five or more. The specific number can be set according to the length of the pipe 80, so as to prevent the pipe 80 from sagging and deforming due to its own weight due to too long an interval. Of course, considering that the pipe 80 is large in size and heavy in weight, in order to prevent the pipe 80 from having less support after cutting and the weight being unevenly distributed at both ends of the support frame 11 and causing it to tilt and fall, more support frames can be used. At least two support frames 11 can be provided on both the left and right sides of the cutting position to provide more stable support for the cut pipe 80.

[0074] Refer to Figure 1 and Figure 2 , the walking frame 20 can move along the first axis X direction, specifically within the length range of the pipe 80, so as to drive the rotating assembly 40 and the laser cutting assembly 50 thereon to move relative to the pipe 80 to reach the position to be cut of the pipe 80. It can be understood that the walking frame 20 can be provided with wheels for walking, and it can walk directly on the floor or on the track 25. Correspondingly, a braking mechanism can also be provided to stop when it reaches the designated position.

[0075] Refer to Figure 1, a clamping mechanism 30 is arranged on the traveling frame 20 and is used for clamping and loosening the pipe 80. The clamping mechanism 30 is located on the traveling frame 20 and can move together with the movement of the traveling frame 20. It can be understood that the clamping mechanism 30 is in a loosened state during the movement of the traveling frame 20. When the traveling frame 20 moves to a specified position and stops, the clamping mechanism 30 can clamp the pipe 80 to fix the pipe 80 relative to the traveling frame 20, preventing the pipe 80 from shifting in position relative to the traveling frame 20 during subsequent cutting processing.

[0076] Referring to Figure 1 and Figure 2 , a rotating assembly 40 is arranged on the traveling frame 20 and can rotate about a first axis X. The rotating assembly 40 is provided with a second through hole 411 for the pipe 80 to pass through. The rotating assembly 40 is located on the traveling frame and can move together with the movement of the traveling frame 20. The rotating assembly 40 is a structure connecting the laser cutting assembly 50 and the traveling frame 20, and it can rotate about the first axis X so that the laser cutting assembly 50 mounted on the rotating assembly 40 can also rotate about the first axis X. The second through hole 411 provided in the rotating assembly 40 is such that when the pipe 80 passes through this through hole, the rotating assembly 40 is located outside the pipe 80. When the rotating assembly 40 rotates one circle, it drives the laser cutting assembly 50 to rotate one circle around the pipe 80. It should be noted that the axial direction of the second through hole 411 also coincides with the first axis X.

[0077] It can be understood that during the process of placing the pipe 80 on each support frame 11, the pipe 80 is pushed along the first axis X direction from one of the support frames 11 at the end, and during the pushing process, the pipe 80 passes through the second through hole 411 of the rotating assembly 40.

[0078] Referring to Figure 1 and Figure 2 , a laser cutting assembly 50 is arranged on the rotating assembly 40 and can move radially along the second through hole 411. The laser cutting assembly 50 is used for emitting laser to cut the pipe 80. Since the laser cutting assembly 50 is arranged on the rotating assembly 40, it can rotate around the first axis X together with the laser cutting assembly 50. And because the pipe 80 passes through the second through hole 411, the laser cutting assembly 50 rotates on the outer periphery of the pipe 80 and can process the outer periphery of the pipe 80. At the same time, since the laser cutting assembly 50 can move radially along the second through hole 411, it can adapt to pipes 80 of different diameters by radial movement, making the distance between the laser cutting assembly 50 and the outer peripheral surface of the pipe 80 appropriate.

[0079] Based on the above structure, the cutting device of the present application can efficiently and accurately complete the cutting task of the pipe 80, and is applicable to pipes 80 with large weights at the same time, reducing the equipment performance and size requirements, and greatly reducing the equipment cost. The following explains the working process of the embodiments of the present application:

[0080] 1. Calculate according to the diameter of the pipe 80, and pre-adjust the height of the support frame 11 so that after the pipe 80 is placed on the support frame 11, the height of its axis is the same as the height of the first axis X. Then the handling equipment transports and pushes the pipe 80 along the direction of the first axis X to each support frame 11 in sequence. During the pushing process, the pipe 80 passes through the second through-hole 411 of the rotating assembly 40. After the pipe 80 is placed on each support frame 11, adjust the direction of the pipe 80 so that the axis of the pipe 80 coincides with the first axis X.

[0081] 2. The walking frame 20 moves along the direction of the first axis X, driving the rotating assembly 40 and the laser cutting assembly 50 thereon to move relative to the pipe 80 to reach the position to be cut of the pipe 80. When the walking frame 20 moves to the specified position and stops, the clamping mechanism 30 clamps the pipe 80 to fix the pipe 80 relative to the walking frame 20, avoiding the position deviation between the pipe 80 and the walking frame 20 during the subsequent cutting process.

[0082] 3. Adjust the laser cutting assembly 50 to move radially along the second through-hole 411 to ensure that the distance between the laser cutting assembly 50 and the outer peripheral surface of the pipe 80 is appropriate.

[0083] 4. Start the laser cutting assembly 50 to emit laser to cut the pipe 80. During cutting, the rotating assembly 40 drives the laser cutting assembly 50 to rotate around the first axis X, so that the entire circumference of the pipe 80 can be cut.

[0084] 5. After cutting is completed, the clamping mechanism 30 releases the pipe 80, and the walking frame 20 moves to the next position to be cut or stops working. The cut pipe 80 can be subjected to subsequent processing or used directly.

[0085] Refer to Figure 1 and Figure 2 , the walking frame 20 includes a chassis 21, a first seat body 23, a second seat body 24, and a first driver (not shown in the figure).

[0086] Refer to Figure 2 and Figure 3 , the chassis 21 is provided with a plurality of walking wheels 22. The chassis 21 can be a rectangular frame structure, leaving space inside the frame structure so as not to touch the support frame 11 during walking. The chassis 21 can be made of high-strength steel or aluminum alloy material. The bottom of the chassis 21 is provided with a plurality of walking wheels 22, and these walking wheels 22 are evenly distributed at the bottom of the chassis 21 to ensure the smoothness and flexibility of the walking frame 20 during movement. The design of the walking wheels 22 enables the walking frame 20 to move smoothly along the ground or the track 25.

[0087] Refer to Figure 1, the first body 23 is disposed at one end of the chassis 21, and the rotating assembly 40 is rotatably disposed on the chassis about the first axis X. The first body 23 is disposed at one end of the chassis 21 and is the support base of the rotating assembly 40. The first body 23 may be a plate-like structure, such as a trapezoidal plate, and reinforcing ribs are further provided at both ends. The first body 23 is made of a high-strength material to bear the weights of the rotating assembly 40 and the laser cutting assembly 50. The rotating assembly 40 is rotatably disposed on the first body 23 about the first axis X to ensure that the rotating assembly 40 can rotate freely and drive the laser cutting assembly 50 to rotate about the axis of the pipe 80.

[0088] Referring to Figure 1 , the second body 24 is disposed at the other end of the chassis 21, and the clamping mechanism 30 is disposed on the second body 24. The second body 24 is disposed at the other end of the chassis 21 and is the support base of the clamping mechanism 30. The second body 24 is made of a high-strength material to ensure the stability and reliability of the clamping mechanism 30. In some embodiments, the second body 24 has a gantry structure, including two columns 241 and a cross beam 242 fixed to the tops of the columns 241. The lower ends of the two columns 241 are fixed to the chassis 21 and are respectively located on both sides of the first axis X. Both the columns 241 and the cross beam 242 are made of high-strength materials to ensure the structural stability and load-bearing capacity. The clamping mechanism 30 can be installed on the two columns 241 and can clamp the middle pipe 80.

[0089] The first driver is used to drive the walking wheels 22 to travel along the first axis X. The first driver is the power source of the walking frame 20. The first driver can be a motor drive system, such as a servo motor or a stepper motor, which drives the walking wheels 22 through a reducer and a transmission mechanism. The first driver is usually connected to the numerical control system to receive the instructions of the numerical control system and achieve precise movement control.

[0090] Referring to Figure 2 and Figure 3 , the cutting device further includes a track 25 and a guide wheel set 26.

[0091] The track 25 is arranged parallel to the first axis X, and the traveling wheels 22 travel along the upper end surface of the track 25. The track 25 is an important component of the cutting device and is designed to be parallel to the first axis X. The arrangement of the track 25 ensures the guiding and stability of the traveling wheels 22 during movement. The track 25 is usually made of high-strength steel or aluminum alloy materials to bear the weight of the traveling frame 20 and the cutting assembly. The upper end surface of the track 25 is the traveling path of the traveling wheels 22, ensuring the smooth movement of the traveling frame 20 along the predetermined path. The traveling wheels 22 are installed on the chassis 21 of the traveling frame 20 and are in direct contact with the upper end surface of the track 25. These traveling wheels 22 are designed to be able to bear large loads and have a low coefficient of friction to reduce the resistance during traveling. The material of the traveling wheels 22 is usually selected as rubber or metal with high wear resistance to ensure good performance during long-term use. Specifically, there are two parallel left and right tracks 25, and correspondingly, multiple traveling wheels 22 are also divided into left and right groups, corresponding to the two tracks 25 respectively.

[0092] Refer to Figure 2 and Figure 3 The guide wheel set 26 includes multiple guide wheels 261 rotatably arranged at the bottom of the chassis 21, and the guide wheels 261 roll along the side wall of the track 25 in a fitting manner. The guide wheel set 26 is another key component of the cutting device and is composed of multiple guide wheels 26. These guide wheels 261 are rotatably arranged at the bottom of the chassis 21 and roll along the side wall of the track 25 in a fitting manner. The design and layout of the guide wheels 261 ensure that the traveling frame 20 does not deviate from the track 25 during movement, providing additional stability and accuracy. The material of the guide wheels 261 is also selected as rubber or metal with high wear resistance to adapt to various use environments. The main function of the guide wheels 261 is to provide lateral support when the traveling frame 20 moves along the track 25, preventing the traveling frame 20 from experiencing side shift or tilt. This design is particularly suitable for occasions that require high-precision cutting operations, ensuring the accuracy and consistency of the cutting process.

[0093] Refer to Figure 1 and Figure 4 , the support frame 11 includes a height adjustment frame 111, a support table 112 arranged on the height adjustment frame 111, and multiple rolling members 113. The support table 112 has a V-shaped positioning portion 1121, and the rolling members 113 are rotatably arranged on the positioning portion 1121. The rotation axis of the rolling members 113 is perpendicular to the first axis X.

[0094] The height adjustment frame 111 is the basic part of the support frame 11. Its design allows the height of the support table 112 to be adjusted to accommodate pipes 80 of different diameters. The height adjustment frame 111 is usually made of high-strength steel or aluminum alloy materials to ensure its load-bearing capacity and stability. This frame can be adjusted in height manually or automatically to adapt to pipes 80 of different diameters and lengths. Specifically, the height adjustment frame 111 can be various conventional lifting frames with height lifting functions.

[0095] Referring to Figure 4 , the V-shaped positioning part 1121 of the support table 112 is designed as two symmetric inclined planes, forming a V-shaped groove. This design enables the circumference of the pipe 80 to be tangent to the inner surface of the V-shaped groove when the pipe 80 is placed on the support table 112. In this way, the center of the pipe 80 can be automatically aligned with the vertex of the V-shaped groove, achieving automatic positioning, reducing the need for manual adjustment, and improving the convenience of operation and the accuracy of cutting. The height adjustment frame 111 of the support frame 11 and the V-shaped positioning part 1121 of the support table 112 work together to ensure that the axis of the pipe 80 coincides with the first axis X of the cutting device. By adjusting the height adjustment frame 111, pipes 80 of different diameters can be adapted, so that the axis of the pipe 80 can be aligned with the first axis X in any case. This design not only improves the cutting accuracy but also enhances the stability of the cutting process.

[0096] On the two inclined planes of the V-shaped positioning part 1121, a plurality of rolling elements 113 are provided. The design of these rolling elements 113 allows the pipe 80 to roll easily along the first axis X direction (i.e., the pushing direction of the pipe 80 during handling). The setting of the rolling elements 113 not only reduces the friction between the pipe 80 and the support table 112 but also makes the pipe 80 more relaxed during handling and positioning, reducing the operation difficulty and labor intensity. Specifically, the two ends of the rolling element 113 are respectively connected with raised rotating supports 114. The rotating supports 114 are raised on the inclined planes of the V-shaped groove, located at both ends of the rolling element 113. Both ends of the rolling element 113 are connected to the rotating supports 114 through a rotating shaft and bearings. This structural design ensures the stability and reliability of the rolling element 113 and is also convenient for the installation and maintenance of the rolling element 113. In some embodiments, the rolling element 113 is a roller, and three rollers are arranged on each inclined plane. The angle between the two inclined planes of the V-shaped positioning part 1121 can specifically be 90°, 110°, 120°, etc.

[0097] Through the design of this V-shaped positioning part 1121 and the height adjustment frame 111, the support frame 11 can not only provide stable support but also adapt to pipes 80 of different specifications, ensuring the accuracy and efficiency of the cutting process. The design of this structure makes the cutting device more flexible and adaptable, can meet the needs of different users, and significantly improves the overall performance and reliability of the cutting operation.

[0098] Referring to Figure 5 and Figure 6 , the clamping mechanism 30 includes two clamping members 31 and a driving assembly 32.

[0099] The two clamping members 31 are oppositely arranged and are respectively located on both sides of the first axis X. The ends of the two clamping members 31 close to each other are provided with clamping portions. The clamping portion includes a first end face 311 and a second end face 312. The first end face 311 and the second end face 312 form an angle. Define a plane that bisects the angle and passes through the first axis X.

[0100] Referring to Figure 5 and Figure 6 , each clamping portion of the clamping member 31 has a first end face 311 and a second end face 312 that form an angle, which is a V-shaped structure. This design of the V-shaped structure enables the clamping portion to closely fit the circumferential surface of the pipe 80 during the clamping process. The two end faces of the V-shaped structure jointly define a symmetry plane, that is, the symmetry plane of the first end face 311 and the second end face 312. Since this plane passes through the first axis X, when clamping, the first end face 311 and the second end face 312 can position the axis of the pipe 80 to ensure that the axis of the pipe 80 coincides with the first axis X. During the clamping process, the V-shaped structures of the two clamping members 31 act together on the pipe 80 to play a centering role. This design enables the axis of the pipe 80 to naturally align with the first axis X when being clamped. This alignment is the key to achieving high-precision cutting, ensuring the stability of the pipe 80 and the cutting quality during the cutting process.

[0101] In some embodiments, the first end face 311 and the second end face 312 form an angle of 90°, 100°, 110° or 120°, etc.

[0102] Referring to Figure 5 and Figure 6 , the driving assembly 32 is used to drive the two clamping members 31 to approach and separate from each other. The driving assembly 32 is responsible for driving the two clamping members 31 to approach and separate from each other. The driving assembly 32 can be a hydraulic system, a pneumatic system or an electric system, and the specific selection depends on the design and use environment of the cutting machine. The movement of the driving assembly 32 needs to be precisely controlled to ensure the uniform distribution of the clamping force and the stable clamping of the pipe 80. In some embodiments, the driving assembly 32 includes two cylinders, which are respectively installed on the two columns 241 of the second seat body 24, and the piston rods of the cylinders are connected to the clamping members 31. In addition, in order to ensure the stability during the telescopic process of the cylinders, guide rods are also provided. Guide holes are provided on the columns 241, and the guide rods are inserted through the guide holes and are connected to the clamping members 31 at one end. Specifically, two guide rods can be provided for each cylinder.

[0103] With this design, the clamping mechanism 30 can not only provide stable and reliable support for the laser cutting machine for the pipe 80, but also ensure the accuracy and efficiency of the cutting process. The design of this structure makes the cutting device more flexible and adaptable, and can meet the needs of different users.

[0104] In order to realize the rotation of the rotating assembly 40 on the walking frame 20 along the first axis X, the following design is carried out in the embodiment of the present application:

[0105] Refer to Figures 7 to 9 , the walking frame 20 is provided with a first through hole 231 penetrating along the first axis X. The rotating assembly 40 includes a central shaft 41 and an end plate 42. The central shaft 41 is rotatably disposed through the first through hole 231. A second through hole 411 for the pipe 80 to pass through is provided on the central shaft 41, and the axis of the first axis X coincides with the axis of the second through hole 411. The end plate 42 is disposed at one end of the central shaft 41, and the laser cutting assembly 50 is disposed on the end plate 42 and can move radially along the second through hole 411.

[0106] Refer to Figures 7 to 9 , the walking frame 20 is provided with a first through hole 231 penetrating along the first axis X. This through hole is the key structure for the rotating assembly 40 to rotate around the first axis X. The diameter and position of the first through hole 231 are precisely designed to ensure that the central shaft 41 can pass through smoothly and achieve precise rotational movement on the walking frame 20. The central shaft 41 is one of the core components of the rotating assembly 40, and it is rotatably disposed through the first through hole 231. The central shaft 41 is usually made of high-strength materials such as alloy steel or stainless steel to ensure its stability and durability under high loads.

[0107] Refer to Figures 7 to 9 , the end plate 42 is disposed at one end of the central shaft 41 and is the installation structure of the laser cutting assembly 50. The design of the end plate 42 needs to consider the weight and working mode of the laser cutting assembly 50 to ensure its stability during rotation. The end plate 42 may be provided with mounting holes or fixing devices for fixing the laser cutting assembly 50 so that it can remain stable during the cutting process. After the central shaft 41 rotates in the first through hole 231, the connected end plate 42 also rotates together, and thus can drive the laser cutting assembly 50 to rotate around the first axis X.

[0108] Refer to Figures 7 to 9, a second through hole 411 for the pipe 80 to pass through is provided on the central axis 41, and the axis of the first axis X coincides with the axis of the second through hole 411. After the central axis 41 rotates, the laser cutting assembly 50 can rotate circumferentially around the pipe 80 to perform circumferential cutting motion. The rotating assembly 40 realizes rotation around the first axis X on the traveling frame 20 (i.e., the first seat body 23) through the cooperation of the central axis 41 and the first through hole 231. This rotation mechanism enables the laser cutting assembly 50 to perform 360° rotary cutting around the axis of the pipe 80, improving the flexibility and coverage of cutting.

[0109] Understandably, in order not to obstruct the pipe 80 from passing through the second through hole 411 and the first through hole 231, a through hole 421 can also be provided on the end plate 42 for the pipe 80 to pass through. Specifically, the end plate 42 can be set as an annular plate-like structure, and its annular center also coincides with the first axis X.

[0110] Refer to Figures 7 to 9 , the laser cutting assembly 50 is provided on the end plate 42 and can move radially along the second through hole 411. This design allows the laser cutting assembly 50 to adjust the distance from the pipe 80 according to the cutting requirements to achieve cutting of pipes 80 with different diameters. The movement of the laser cutting assembly 50 can be realized through manual adjustment or an automatic control system to ensure the flexibility and accuracy of the cutting process.

[0111] Refer to Figures 7 to 9 , the rotating assembly 40 further includes a rotation driving assembly 43. The rotation driving assembly 43 is provided on the shape frame and is used to drive the central axis 41 to rotate. The rotation driving assembly 43 can be arranged at one end of the central axis 41 away from the laser cutting assembly 50. That is, both ends of the central axis 41 extend out of the first through hole 231. One end is connected to the end plate 42 to install the laser cutting assembly 50, and the other end is connected to the rotation driving assembly 43. The rotation driving assembly 43 drives the central axis 41 to rotate, thereby driving the laser cutting assembly 50 to perform circumferential cutting on the pipe 80.

[0112] Refer to Figures 7 to 9 , the rotation driving assembly 43 includes an annular outer gear 431, a driving gear 432, and a second driver 433. The annular outer gear 431 is provided on the central axis 41 and is coaxially arranged with the central axis 41. The driving gear 432 meshes with the annular outer gear 431, and the second driver 433 is provided on the traveling frame 20 and is used to drive the driving gear 432 to rotate.

[0113] Refer to Figures 7 to 9, the annular external gear 431 is arranged on the central shaft 41 and coaxially with the central shaft 41. This design enables the annular external gear 431 to directly drive the rotation of the central shaft 41. The size and number of teeth of the annular external gear 431 need to match the driving gear 432 to ensure the smoothness and efficiency of the transmission. The driving gear 432 meshes with the annular external gear 431 to form a pair of gear transmission pairs. This meshing relationship ensures that the rotation of the driving gear 432 can be directly transmitted to the annular external gear 431, and then drive the central shaft 41 to rotate. The meshing accuracy and lubrication condition of the gears have an important impact on the operation stability and service life of the entire rotary drive assembly 43.

[0114] Refer to Figures 7 to 9 , the second driver 433 is arranged on the traveling frame 20, specifically located on the first seat body 23, and is used to drive the driving gear 432 to rotate. The second driver 433 can be an electric motor, a hydraulic motor, a pneumatic motor, etc., and the specific selection depends on the design and use environment of the cutting machine. The design of the second driver 433 needs to ensure that it can provide sufficient torque and rotational speed to drive the entire rotating assembly 40. By driving the driving gear 432 to rotate through the second driver 433, and then driving the annular external gear 431 to rotate, the central shaft 41 rotates synchronously, and finally drives the laser cutting assembly 50 to rotate around the pipe 80 for circumferential cutting. The design of the entire transmission chain needs to consider the transmission efficiency and response speed to ensure the continuity and stability of the cutting process.

[0115] Refer to Figures 7 to 9 , a gear cover plate 434 can also be provided to cover the annular external gear 431 and the driving gear 432 to prevent debris during the cutting process from getting stuck between the gears and causing failures.

[0116] Refer to Figures 7 to 9 , the cutting device further includes a radial adjustment mechanism 60, and the radial adjustment mechanism 60 includes a guide rail 61, a sliding member 62 and a third driver 63. The guide rail 61 is arranged on the rotating assembly 40 perpendicular to the first axis X. The sliding member 62 can slide along the guide rail 61, the laser cutting assembly 50 is arranged on the sliding member 62, and the perpendicular line of the laser cutting assembly 50 to the first axis X is parallel to the guide rail 61. The third driver 63 is used to drive the sliding member 62 to move along the guide rail 61.

[0117] The guide rail 61 is arranged on the rotating assembly 40 perpendicular to the first axis X, specifically on the end plate 42. This perpendicular layout ensures that when the sliding member 62 moves along the guide rail 61, the laser cutting assembly 50 can accurately cut the pipe 80 radially.

[0118] An installation plate or fixing device can be provided on the sliding member 62 for installing the laser cutting assembly 50.

[0119] Refer to Figures 7 to 9, the laser cutting assembly 50 is provided on the sliding member 62, and the perpendicular line to the first axis X is parallel to the guide rail 61. This design enables the laser cutting assembly 50 to move radially along the guide rail 61 and adjust the distance from the outer peripheral surface of the pipe 80. The installation of the laser cutting assembly 50 needs to ensure its stable connection with the sliding member 62 to avoid deviation during movement.

[0120] Referring to Figures 7 to 9 , the third driver 63 is used to drive the sliding member 62 to move along the guide rail 61. The third driver 63 can be a linear motor, a servo motor or other types of driving devices. By driving the sliding member 62 to slide along the guide rail 61 through the third driver 63, the laser cutting assembly 50 can move radially in the second through hole 411. This radial adjustment enables the laser cutting assembly 50 to adjust the distance from the outer peripheral surface of the pipe 80 according to the diameter of the pipe 80 and the cutting requirements, and achieve precise cutting of pipes 80 with different diameters. Through this design, the radial adjustment mechanism 60 provides the laser cutting machine with a flexible and precise radial adjustment ability, which is suitable for cutting pipes 80 with different diameters and shapes. The design of this structure makes the cutting device more efficient and adaptable, and can meet the needs of different users.

[0121] In some embodiments, the third driver 63 includes a motor, a lead screw and a nut. The nut is arranged on the sliding member 62, and the motor drives the lead screw to rotate, thereby pushing the nut to move and driving the sliding member 62 to move on the guide rail 61.

[0122] Furthermore, the laser cutting assembly 50 includes a cutting head 51 and an optical fiber tube 52. The cutting head 51 is arranged on the rotating assembly 40, and one end of the optical fiber tube 52 is connected to the cutting head 51. The cutting head 51 is arranged on the rotating assembly 40 and directly participates in the cutting process. One end of the optical fiber tube 52 is connected to the cutting head 51, and the other end is connected to the laser generator, which is responsible for transmitting the laser from the generator to the cutting head 51.

[0123] Referring to Figure 1 , Figure 10 and Figure 11 , the cutting device further includes an optical fiber arrangement mechanism 70. The optical fiber arrangement mechanism 70 includes a winding ring 71, a guide wheel 72, a movable member 73, a tensioning wheel 74 and a force applying member 75. These components work together to ensure the stability and tension of the optical fiber tube 52 during the rotation of the laser cutting head 51, and ensure that the optical fiber should not be broken due to excessive winding.

[0124] The winding ring 71 is arranged on the rotating assembly 40 and is coaxial with the first axis X. The circumferential surface of the winding ring 71 is provided with a first groove 711 surrounding one circle for winding the optical fiber tube 52. The winding ring 71 rotates together with the rotating assembly 40 when it rotates, and the optical fiber tube 52 will be wound in or unwound from the first groove 711 as it rotates.

[0125] The guide wheel 72 is rotatably arranged on the traveling frame 20, and the optical fiber can bypass the guide wheel 72 to straighten the optical fiber.

[0126] Refer to Figure 1 、 Figure 10 and Figure 11 As shown in FIGS.

[0127] Refer to Figure 1 、 Figure 10 and Figure 11 The movable member 73 is arranged on the traveling frame 20 and can move along the first direction Z closer to or away from the guide wheel 72. The first direction Z can be horizontal, vertical or inclined. The tensioning wheel 74 is rotatably arranged on the movable member 73, and the other end of the optical fiber tube 52 is wound around the first groove 711 and sequentially bypasses the guide wheel 72 and the tensioning wheel 74 and is connected to the laser generator. This design enables the optical fiber sorting mechanism 70 to dynamically adjust the distance between the tensioning wheel 74 and the guide wheel 72 according to the position of the cutting head 51 and the tension of the optical fiber tube 52 to ensure the tension of the optical fiber. For example, when the cutting head 51 rotates clockwise around the first axis X, at this time, the winding ring 71 winds more of the optical fiber tube 52 in the first groove 711, and the length of the outer part of the optical fiber tube 52 decreases. At this time, the tensioning wheel 74 moves closer to the guide wheel 72 to reduce the distance between the two, adapting to the reduction in the length of the optical fiber tube 52 and avoiding breaking the optical fiber tube 52. When the cutting head 51 rotates clockwise around the first axis X, at this time, the winding ring 71 unwinds more of the optical fiber tube 52, and the length of the outer part of the optical fiber tube 52 increases. At this time, the tensioning wheel 74 moves away from the guide wheel 72, and the distance between the two becomes larger, adapting to the increase in the length of the optical fiber tube 52 and avoiding the optical fiber tube 52 from being loose and interfering with other structures during winding.

[0128] Refer to Figure 1 、 Figure 10 and Figure 11 On the circumferences of the guide wheel and the tensioning wheel 74, grooves with a semicircular cross-section matching the optical fiber tube 52 are provided to prevent the optical fiber tube 52 from detaching from the guide wheel and the tensioning wheel 74 when they rotate.

[0129] Among them, the force - applying member 75 can be an elastic member or a counterweight.

[0130] Referring to Figure 1 、 Figure 10 and Figure 11 Figure, the optical - fiber arranging mechanism 70 further includes a fixed pulley 76 and a traction wire 77.

[0131] The fixed pulley 76 is rotatably arranged on the traveling frame 20, and the axis of the fixed pulley 76 is higher than the axes of the guiding wheel 72 and the tensioning wheel 74. One end of the traction wire 77 is connected to the movable member 73, and the other end bypasses the fixed pulley 76 from above and is connected to the force - applying member 75. The force - applying member 75 is a counterweight, and the first direction Z is the height direction.

[0132] The function of the fixed pulley 76 is to change the direction of the traction wire 77, and further change the direction of the force actually applied by the force - applying member 75 on the tensioning wheel 74. That is, through the traction wire and the fixed pulley 76, the gravity of the force - applying member 75 is changed into an upward pulling force on the tensioning wheel 74. Thus, as the cutting head 51 rotates, the tensioning wheel 74 can be controlled to move up and down along the first direction Z (i.e., the height direction) to always keep the optical - fiber tube 52 in tension.

[0133] A bracket can be arranged on the traveling frame 20, and the guiding wheel, the fixed pulley 76, the movable member 73 and the traction wheel are all arranged on this bracket. A slide rail arranged vertically can be arranged on this bracket, and the movable member 73 can slide up and down along this slide rail, and the traction wheel is arranged on the movable member 73 and slides up and down with it.

[0134] The above - mentioned are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included within the protection scope of the present application.
