Description

Technical Field

[0001] The present application belongs to the technical field of tube cutting machines, and specifically relates to a laser tube cutting machine. Background Art

[0002] Laser cutting is a new type of cutting technology that uses a high-energy-density laser beam as a heat source to cut materials. Laser tube cutting machine is a commonly used tube cutting equipment, which is used to cut tube materials of specific sizes from longer tubes. It has the advantages of low cutting stress and high cutting accuracy.

[0003] At present, the laser tube cutting machine includes a bed, a front chuck at one end of the bed, a rear chuck at the other end of the bed, and a laser cutting head on the bed. The front chuck and the rear chuck are located in the middle position in the width direction of the bed. The rear chuck can move along the length direction of the bed so that the rear chuck drives the tube to move, and then the position where the tube needs to be cut is moved to directly below the laser cutting head.

[0004] However, since the front chuck and the rear chuck are located in the middle position in the width direction of the bed, the loading device matched with the laser tube cutting machine needs to push the tube to the middle position in the width direction of the bed, thereby increasing the loading stroke of the loading device, affecting the loading efficiency of the tube, and further affecting the cutting efficiency of the laser tube cutting machine. Utility Model Content

[0005] The present application provides a laser tube cutting machine to improve the feeding efficiency of tubes, thereby improving the cutting efficiency of the laser tube cutting machine on tubes.

[0006] The technical solution adopted in this application is:

[0007] A laser tube cutting machine comprises a bed, a front chuck arranged at one end of the bed, a rear chuck arranged at the other end of the bed and a cutting assembly arranged on the bed for cutting tubes, wherein the front chuck and the rear chuck are both located on the side of the bed and are arranged opposite to each other, and the rear chuck can move along the length direction of the bed to push the clamped tube.

[0008] By adopting the above technical solution, when cutting the tube, the feeding device matched with the laser tube cutting machine pushes the tube so that the tube moves to be coaxial with the front chuck and the rear chuck, and then the rear chuck moves along the length direction of the bed so that the rear chuck clamps the tube, and then the rear chuck continues to move along the length direction of the bed, and then the end of the tube away from the rear chuck passes through the front chuck, and the position where the tube needs to be cut moves to just below the cutting assembly, and then the cutting assembly is started so that the cutting assembly cuts the tube. Since the front chuck and the rear chuck are both located on the side of the bed and are arranged opposite to each other, the feeding stroke of the feeding device matched with the laser tube cutting machine for the tube is reduced, thereby improving the feeding efficiency of the tube, and then improving the cutting efficiency of the laser tube cutting machine for the tube.

[0009] Optionally, the bed is slidably connected to a movable seat, the movable seat has a protruding portion located at a side of the bed, and the rear chuck is arranged on the protruding portion.

[0010] By adopting the above technical solution, when cutting the pipe, the movable seat and the bed slide relative to each other, and then the movable seat drives the rear chuck to move, thereby realizing the movement of the rear chuck along the length direction of the bed. Since the rear chuck is arranged on the protruding part, the rear chuck is located on the side of the bed, and at the same time, the connection stability between the rear chuck and the bed is increased, thereby ensuring the cutting accuracy of the pipe.

[0011] Optionally, the movable seat is provided with a driving member, the output shaft of the driving member is provided with transmission teeth, the bed is provided with matching teeth extending along its own length direction, and the transmission teeth are meshed and transmission-connected with the matching teeth.

[0012] By adopting the above technical solution, when cutting the pipe, the driving part is started, and the driving part drives the transmission teeth to rotate. Since the transmission teeth are meshed and connected with the matching teeth, the transmission teeth drive the driving part and the moving seat to move along the length direction of the matching teeth, thereby realizing the movement of the rear chuck along the length direction of the bed, thereby increasing the accuracy of the movement of the rear chuck, improving the cutting accuracy of the pipe, and improving the customer's usage experience.

[0013] Optionally, the movable seat is provided with an adjustment block, and the adjustment block is movably connected with an adjustment member acting on the driving member, and the adjustment member can move relative to the adjustment block to adjust the matching clearance between the transmission tooth and the matching tooth.

[0014] By adopting the above technical solution, when adjusting the fitting clearance between the transmission tooth and the mating tooth, the adjusting member is operated so that the adjusting member adjusts the driving member under the action of the adjusting block, and then the driving member drives the transmission tooth to move, so that the fitting clearance between the transmission tooth and the mating tooth is adjusted, thereby maintaining a high meshing accuracy between the transmission tooth and the mating tooth, and at the same time reducing the noise when the transmission tooth and the mating tooth move relative to each other, further improving the customer's usage experience.

[0015] Optionally, the protruding portion is provided with a positioning block, and a positioning piece acting on the rear chuck is movably connected to the positioning block, and the positioning piece can move relative to the positioning block to make the rear chuck coaxial with the front chuck.

[0016] By adopting the above technical solution, as the use time of the laser tube cutting machine continues to increase, the front chuck and the rear chuck may become skewed. At this time, the positioning piece can be adjusted so that the positioning piece drives the rear chuck to move under the action of the positioning block, so that the rear chuck returns to a coaxial state with the front chuck, so as to achieve the effect of extending the service life of the laser tube cutting machine, while ensuring the cutting accuracy of the tube, and further improving the customer's user experience.

[0017] Optionally, the front chuck can be moved along the length direction of the bed so that the front chuck has a first position located on the side of the cutting assembly away from the rear chuck and a second position located on the side of the cutting assembly toward the rear chuck.

[0018] By adopting the above technical solution, when cutting the last section of the pipe, there are two processing methods according to the length of the cut pipe. When the remaining pipe is long, the front chuck moves to the first position so that the front chuck and the rear chuck clamp the remaining pipe at the same time; when the remaining pipe is short, the front chuck moves to the second position, and the rear chuck passes through the front chuck at the same time, so that the rear chuck clamps the remaining pipe alone, thereby realizing jump-cutting of the pipe to ensure that the remaining pipe is the shortest tail, thereby improving the utilization rate of the pipe and increasing the flexibility of the laser pipe cutting machine.

[0019] Optionally, the bed includes a main body and an extension seat arranged at one end of the main body, the extension seat is located on the side of the main body, and the front chuck is arranged on the extension seat.

[0020] By adopting the above technical solution, the front chuck is arranged on the extension seat, so that the front chuck is located on the side of the bed, and the front chuck and the rear chuck are arranged opposite to each other. At the same time, the extension seat is located on the side of the main body, which can also increase the stability of the bed and avoid the situation where the front chuck and the rear chuck are both located on the side of the bed, resulting in unbalanced force at both ends in the width direction of the bed, thereby increasing the stability of the laser tube cutting machine.

[0021] Optionally, the main body is provided with a first track and a second track located on one side of the first track, the first track extends to the extension seat, the extension seat is provided with a third track located on the side of the first track away from the second track, the rear chuck is slidably connected to the first track and the second track, and the front chuck is slidably connected to the first track and the third track.

[0022] By adopting the above technical scheme, when the rear chuck moves along the length direction of the bed, the rear chuck slides relatively with the first track and the second track, so that the first track and the second track jointly guide the movement of the rear chuck, so as to increase the stability of the rear chuck when moving; when the front chuck moves along the length direction of the bed, the front chuck slides relatively with the first track and the third track, so that the first track and the third track jointly guide the movement of the front chuck, so as to increase the stability of the front chuck when moving; at the same time, the front chuck and the rear chuck share the first track, which can reduce the production cost of the laser tube cutting machine and increase the structural compactness of the laser tube cutting machine.

[0023] Optionally, the bed is provided with a mounting seat, the front chuck is arranged on the mounting seat, a limiting block is provided on the mounting seat, a limiting piece acting on the front chuck is movably connected to the limiting block, and the limiting piece can move relative to the limiting block to make the front chuck coaxial with the rear chuck.

[0024] By adopting the above technical solution, as the use time of the laser tube cutting machine continues to increase, the front chuck and the rear chuck may become skewed. At this time, the limit member can be adjusted so that the limit member drives the front chuck to move under the action of the limit block, so that the front chuck returns to a coaxial state with the rear chuck, so as to achieve the effect of extending the service life of the laser tube cutting machine, while ensuring the cutting accuracy of the tube, and further improving the customer's user experience; in addition, both the front chuck and the rear chuck can be adjusted, which can further ensure that the front chuck and the rear chuck can be in a coaxial state, so as to further increase the service life of the laser tube cutting machine.

[0025] Optionally, the cutting assembly includes a support beam disposed on the bed, a crossbeam with one end disposed on the top of the support beam, and a cutting head disposed on the crossbeam, and the support beam is arranged to avoid the front chuck.

[0026] By adopting the above technical solution, the support beam and the front chuck are arranged to avoid each other, so that the cutting assembly and the front chuck can avoid each other, and then the front chuck can move between the first position and the second position to ensure the shortest tail material when cutting the pipe, improve the utilization rate of the pipe, and increase the flexibility of the laser pipe cutting machine.

[0027] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0028] 1. The laser tube cutting machine in the present application includes a bed, a front chuck arranged at one end of the bed, a rear chuck arranged at the other end of the bed, and a cutting assembly arranged on the bed for cutting tubes. The front chuck and the rear chuck are both located on the side of the bed and are arranged opposite to each other. The rear chuck can move along the length direction of the bed to push the clamped tube. Since the front chuck and the rear chuck are both located on the side of the bed, the distance between the feeding device and the front chuck and the rear chuck is closer, thereby reducing the feeding stroke of the feeding device matched with the laser tube cutting machine for the tube, improving the feeding efficiency of the tube, and then improving the cutting efficiency of the laser tube cutting machine for the tube.

[0029] 2. The bed in the present application is slidably connected to a movable seat, which has a protruding portion located on the side of the bed, and the rear chuck is arranged on the protruding portion, thereby realizing that the rear chuck is located on the side of the bed, while increasing the connection stability between the rear chuck and the bed, thereby ensuring the cutting accuracy of the pipe.

[0048] Reference Figures 1 to 6 A laser tube cutting machine includes a bed 1, a front chuck 2 arranged at one end of the bed 1, a rear chuck 3 arranged at the other end of the bed 1, and a cutting assembly 4 arranged on the bed 1 for cutting tubes. The front chuck 2 and the rear chuck 3 are both located on the side of the bed 1 and are arranged opposite to each other. The rear chuck 3 can move along the length direction of the bed 1 to push the clamped tube.

[0049] When cutting the tube, the feeding device matched with the laser tube cutting machine pushes the tube so that the tube moves to be coaxial with the front chuck 2 and the rear chuck 3, and then the rear chuck 3 moves along the length direction of the bed 1 so that the rear chuck 3 clamps the tube, and then the rear chuck 3 continues to move along the length direction of the bed 1, and then the end of the tube away from the rear chuck 3 passes through the front chuck 2, and the position where the tube needs to be cut moves to just below the cutting assembly 4, and then the cutting assembly 4 is started so that the cutting assembly 4 cuts the tube. Since the front chuck 2 and the rear chuck 3 are both located on the side of the bed 1 and are arranged opposite to each other, the feeding stroke of the feeding device matched with the laser tube cutting machine for the tube is reduced, thereby improving the feeding efficiency of the tube, and then improving the cutting efficiency of the laser tube cutting machine for the tube.

[0050] The present application does not specifically limit the arrangement of the rear chuck 3 and the front chuck 2 on the side of the bed 1, and any one of the following embodiments may be adopted:

[0051] Embodiment 1. In this embodiment, the side of the bed 1 has an installation area, and the rear chuck 3 and the front chuck 2 are arranged in the installation area, that is, the rear chuck 3 and the front chuck 2 are both installed on the side of the bed 1 to reduce the production cost of the laser tube cutting machine.

[0052] Implementation method 2. In this implementation method, refer to Figure 1 and Figure 4The bed 1 is slidably connected to a moving seat 111 . The moving seat 111 has a protruding portion 115 located at a side of the bed 1 . The rear chuck 3 is disposed at the protruding portion 115 .

[0053] Specifically, when cutting the pipe, the movable seat 111 and the bed 1 slide relative to each other, and then the movable seat 111 drives the rear chuck 3 to move, thereby realizing the movement of the rear chuck 3 along the length direction of the bed 1. Since the rear chuck 3 is arranged on the protruding portion 115, the rear chuck 3 is located on the side of the bed 1, and at the same time, the connection stability between the rear chuck 3 and the bed 1 is increased, thereby ensuring the cutting accuracy of the pipe.

[0054] The present application does not specifically limit the structure of the protruding portion 115. Preferably, refer to Figure 4 The protruding portion 115 is a block-shaped structure extending from the movable seat 111 toward the side of the bed 1 to increase the stability of the rear chuck 3. In other embodiments, the protruding portion 115 can also be a plate-shaped structure or other structures. As long as the rear chuck 3 can be installed, the protruding portion 115 can be any structure.

[0055] Reference Figure 1 , Figure 2 and Figure 5 The bed 1 includes a main body 11 and an extension seat 12 arranged at one end of the main body 11 . The extension seat 12 is located at the side of the main body 11 , and the front chuck 2 is arranged on the extension seat 12 .

[0056] The front chuck 2 is arranged on the extension seat 12, so that the front chuck 2 is located on the side of the bed 1, and the front chuck 2 and the rear chuck 3 are arranged opposite to each other. At the same time, the extension seat 12 is located on the side of the main body 11, which can also increase the stability of the bed 1 and avoid the situation where the front chuck 2 and the rear chuck 3 are both located on the side of the bed 1, resulting in unbalanced force at both ends of the bed 1 in the width direction, thereby increasing the stability of the laser tube cutting machine.

[0057] The present application does not specifically limit the driving method of the movable seat 111, and it can adopt any one of the following embodiments:

[0058] Embodiment 1. In this embodiment, the bed 1 is provided with a cylinder, a hydraulic cylinder or an electric push rod, and the cylinder body of the cylinder, the hydraulic cylinder or the electric push rod is arranged on the bed 1. The piston rod of the cylinder, the hydraulic cylinder or the electric push rod acts on the movable seat 111, so that when the cylinder, the hydraulic cylinder or the electric push rod is working, the piston rod pushes the movable seat 111 to move along the length direction of the bed 1.

[0059] Embodiment 2, in this embodiment, refer to Figure 3 and Figure 4The movable seat 111 is provided with a driving member 117, the output shaft of the driving member 117 is provided with a transmission tooth 118, the bed 1 is provided with a matching tooth 112 extending along its own length direction, and the transmission tooth 118 is meshed and transmission-connected with the matching tooth 112.

[0060] Specifically, the driving member 117 is a servo motor, the transmission tooth 118 is a gear coaxially fixedly connected to the output shaft of the servo motor, the matching tooth 112 is a rack arranged parallel to the length direction of the main body 11, and the rack is fixedly connected to the main body 11, and the gear and the rack are meshed and transmitted. That is to say, when the rear chuck 3 moves along the length direction of the bed 1, the servo motor is started, the servo motor drives the gear to rotate, and then the gear and the rack rotate relative to each other. At the same time, the gear drives the servo motor and the moving seat 111 to move along the length direction of the bed 1, thereby increasing the accuracy of the movement of the rear chuck 3, improving the cutting accuracy of the pipe, and thus improving the customer's usage experience.

[0061] It should be noted that a reciprocating screw and a sliding block may be used to replace the design of the transmission teeth 118 and the matching teeth 112 .

[0062] Further, see Figure 4 The movable seat 111 is provided with an adjusting block 119 , and an adjusting member acting on the driving member 117 is movably connected to the adjusting block 119 . The adjusting member can move relative to the adjusting block 119 to adjust the matching clearance between the transmission tooth 118 and the matching tooth 112 .

[0063] When adjusting the fitting clearance between the transmission tooth 118 and the mating tooth 112, operate the adjusting member so that the adjusting member adjusts the driving member 117 under the action of the adjusting block 119, and then the driving member 117 drives the transmission tooth 118 to move, so that the fitting clearance between the transmission tooth 118 and the mating tooth 112 is adjusted, thereby maintaining a high meshing accuracy between the transmission tooth 118 and the mating tooth 112, and at the same time reducing the noise when the transmission tooth 118 and the mating tooth 112 move relative to each other, further improving the customer's usage experience.

[0064] The present application does not specifically limit the structure of the adjusting member. Preferably, the adjusting member is an adjusting rod, which is threadedly disposed in the adjusting block 119, and has a connecting end rotatably connected to the driving member 117 and an adjusting end located at the end of the adjusting block 119 away from the driving member 117. When adjusting the gap between the transmission tooth 118 and the mating tooth 112, the adjusting end is rotated to make the adjusting rod and the adjusting block 119 threadably rotate, and then the connecting end of the adjusting rod drives the driving member 117 to move toward or away from the adjusting block 119, so that the driving member 117 drives the transmission tooth 118 to move, so as to adjust the gap between the transmission tooth 118 and the mating tooth 112. In this process, it is only necessary to rotate the adjusting rod, so as to achieve the effect of facilitating the adjustment of the gap between the transmission tooth 118 and the mating tooth 112.

[0065] In other implementation examples, two adjustment blocks 119 are provided and are respectively located on opposite sides of the driving member 117. The adjusting member is a wedge block and two corresponding adjustment blocks 119 are provided. Each wedge block is located between the adjustment block 119 and the driving member 117, so that when adjusting the gap between the transmission tooth 118 and the mating tooth 112, it is only necessary to pull one of the wedge blocks and press the other wedge block.

[0066] In a preferred embodiment, referring to Figure 4 The protruding portion 115 is provided with a positioning block 116 , and a positioning piece acting on the rear chuck 3 is movably connected to the positioning block 116 , and the positioning piece can move relative to the positioning block 116 to make the rear chuck 3 coaxial with the front chuck 2 .

[0067] Specifically, as the use time of the laser tube cutting machine continues to increase, the front chuck 2 and the rear chuck 3 may become skewed. At this time, the positioning piece can be adjusted so that the positioning piece drives the rear chuck 3 to move under the action of the positioning block 116, so that the rear chuck 3 returns to a coaxial state with the front chuck 2, so as to achieve the effect of extending the service life of the laser tube cutting machine, while ensuring the cutting accuracy of the tube, and further improving the customer's user experience.

[0068] The present application does not specifically limit the structure of the positioning member. Preferably, two positioning blocks 116 are provided and are respectively located on opposite sides of the rear chuck 3. The positioning member is a positioning rod threadedly penetrated through the positioning block 116. One end of the positioning rod abuts against the rear chuck 3, so that when adjusting the rear chuck 3, it is only necessary to rotate the positioning rod, thereby achieving the effect of facilitating the adjustment of the rear chuck 3. In other embodiments, two positioning blocks 116 are provided and are respectively located on opposite sides of the rear chuck 3. The positioning member is a trapezoidal block located between the positioning block 116 and the rear chuck 3. The trapezoidal block squeezes the rear chuck 3 to achieve the adjustment of the rear chuck 3.

[0069] In a preferred embodiment, referring to Figure 1 and Figure 3 The front chuck 2 can move along the length direction of the bed 1 so that the front chuck 2 has a first position located on the side of the cutting assembly 4 away from the rear chuck 3 and a second position located on the side of the cutting assembly 4 toward the rear chuck 3 .

[0070] Specifically, when cutting the last section of the pipe, there are two processing methods according to the length of the cut pipe. When the remaining pipe is long, the front chuck 2 moves to the first position so that the front chuck 2 and the rear chuck 3 can clamp the remaining pipe at the same time; when the remaining pipe is short, the front chuck 2 moves to the second position, and the rear chuck 3 passes through the front chuck 2 so that the rear chuck 3 can clamp the remaining pipe alone, thereby realizing a jump-type cutting of the pipe to ensure that the remaining pipe is the shortest tail material, thereby improving the utilization rate of the pipe and increasing the flexibility of the laser pipe cutting machine.

[0071] The present application does not make any specific limitation on the driving method of the front chuck 2 , which adopts the same driving method as the rear chuck 3 .

[0072] Further, see Figure 3 The main body 11 is provided with a first track 113 and a second track 114 located on one side of the first track 113. The first track 113 extends to the extension seat 12. The extension seat 12 is provided with a third track 121 located on the side of the first track 113 away from the second track 114. The rear chuck 3 is slidably connected to the first track 113 and the second track 114, and the front chuck 2 is slidably connected to the first track 113 and the third track 121.

[0073] Specifically, the first track 113 , the second track 114 and the third track 121 are all arranged in parallel and spaced apart from each other and are arranged parallel to the length direction of the body 11 .

[0074] When the rear chuck 3 moves along the length direction of the bed 1, the rear chuck 3 slides relative to the first track 113 and the second track 114, so that the first track 113 and the second track 114 jointly guide the movement of the rear chuck 3, so as to increase the stability of the rear chuck 3 when moving; when the front chuck 2 moves along the length direction of the bed 1, the front chuck 2 slides relative to the first track 113 and the third track 121, so that the first track 113 and the third track 121 jointly guide the movement of the front chuck 2, so as to increase the stability of the front chuck 2 when moving; at the same time, the front chuck 2 and the rear chuck 3 share the first track 113, which can reduce the production cost of the laser tube cutting machine and increase the structural compactness of the laser tube cutting machine.

[0075] Better, refer to Figure 3 , Figure 4 and Figure 5The movable seat 111 is provided with a first slider 122 that slides with the first track 113 and the second track 114, and the front chuck 2 is provided with a second slider 211 that slides with the first track 113 and the third track 121, so as to increase the connection stability between the rear chuck 3 and the body 11 and increase the connection stability between the front chuck 2 and the extension seat 12, and further increase the stability of the front chuck 2 and the rear chuck 3 during movement.

[0076] In a preferred embodiment, referring to Figure 1 and Figure 5 The bed 1 is provided with a mounting seat 21, the front chuck 2 is arranged on the mounting seat 21, a limiting block 212 is arranged on the mounting seat 21, a limiting member acting on the front chuck 2 is movably connected to the limiting block 212, and the limiting member can move relative to the limiting block 212 to make the front chuck 2 and the rear chuck 3 coaxial.

[0077] Specifically, the second slider 211 is disposed on the mounting seat 21, that is, the mounting seat 21 is slidably connected to the extension seat 12 through the second slider 211. Similarly, as the use time of the laser tube cutting machine continues to increase, the front chuck 2 and the rear chuck 3 may be skewed. At this time, the limiter can be adjusted so that the limiter drives the front chuck 2 to move under the action of the limiter block 212, so that the front chuck 2 returns to a coaxial state with the rear chuck 3, so as to achieve the effect of extending the service life of the laser tube cutting machine, while ensuring the cutting accuracy of the tube, and further improving the customer's experience; in addition, both the front chuck 2 and the rear chuck 3 can be adjusted, which can further ensure that the front chuck 2 and the rear chuck 3 can be in a coaxial state, so as to further increase the service life of the laser tube cutting machine.

[0078] The present application does not specifically limit the structure of the limiter. Preferably, two limiter blocks 212 are provided and are respectively located on opposite sides of the front chuck 2. The limiter is a limiter rod threadedly penetrated through the positioning block 116. One end of the limiter rod abuts against the front chuck 2, so that when adjusting the front chuck 2, only the limiter rod needs to be rotated, thereby achieving the effect of facilitating the adjustment of the front chuck 2. In other embodiments, two limiter blocks 212 are provided and are respectively located on opposite sides of the front chuck 2. The limiter is a wedge-shaped block located between the limiter block 212 and the front chuck 2. The wedge-shaped block squeezes the front chuck 2 to achieve the adjustment of the front chuck 2.

[0079] In a preferred embodiment, referring to Figure 1 and Figure 6 The cutting assembly 4 includes a support beam 41 disposed on the bed 1 , a cross beam 42 with one end disposed on the top of the support beam 41 , and a cutting head 43 disposed on the cross beam 42 . The support beam 41 and the front chuck 2 are arranged to avoid each other.

[0080] That is to say, the support beam 41 and the cross beam 42 together form an "L"-shaped structure, and the support beam 41 is arranged on the main body 11 so that the support beam 41 and the front chuck 2 form an avoidance to ensure the normal movement of the front chuck 2, thereby ensuring the flexibility of the laser tube cutting machine.

[0081] Preferably, the cross beam 42 is arranged perpendicular to the length direction of the main body 11, and the cutting head 43 can move along the length direction of the cross beam 42 to adjust the position of the cutting head 43. The cutting head 43 can move along the length direction of the support beam 41 so that the distance between the cutting head 43 and the pipe to be cut can be adjusted to ensure the cutting efficiency of the pipe.

[0082] In a preferred embodiment, referring to Figure 6 The support beam 41 is provided with a reinforcing plate 411, and the reinforcing plate 411 is fixedly connected to the cross beam 42, so that the reinforcing plate 411 can reinforce the connection position between the support beam 41 and the cross beam 42. At the same time, the reinforcing plate 411 can also support the cross beam 42 to increase the stability of the cross beam 42, thereby increasing the stability of the cutting head 43, and further ensuring the cutting accuracy of the laser cutting machine on the pipe.

[0083] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0084] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0085] The above is only the embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
