[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0018] like Figure 1-Figure 5As shown, a laser tube cutting machine described in the present invention comprises a cutting machine main frame 1, an output end through a spacing control group 3, a laser cutting component 4 and a PLC control module 5. The cutting machine main frame 1 and the output end through the spacing control group 3 are both provided with a cutting dynamic offset monitoring module 2. The laser cutting component 4 is arranged between two cutting dynamic offset monitoring modules 2. An uncut feed end adjustment module 7 is arranged at one end of the cutting machine main frame 1. A cut adjustment end follower module 6 is arranged at one end of the output end through the spacing control group 3. The output ends of the cut adjustment end follower module 6 and the uncut feed end adjustment module 7 are respectively connected to the two groups of cutting dynamic offset monitoring modules 2. The PLC control module 5 is used to control the rotation path of the cut adjustment end follower module 6 and the uncut feed end adjustment module 7, so as to calibrate the output angle of the cutting dynamic offset monitoring module 2 after a single cutting action is completed. The cutting dynamic offset monitoring module 2 comprises The cutting angle dynamic connection part 21, the offset correction callback unit 22, the radial deviation surface monitoring unit 23 and the axial offset surface monitoring unit 24, the cutting angle dynamic connection part 21 is rotatably connected to the inner side of the cutting machine main frame 1, the offset correction callback unit 22 is symmetrically installed on the outer wall of the cutting angle dynamic connection part 21 at four corners, the inner side of the offset correction callback unit 22 is provided with a radial deviation surface monitoring unit 23, the axial offset surface monitoring unit 24 is rotatably connected to the inner side of the radial deviation surface monitoring unit 23, the cutting angle dynamic connection part 21 is connected to the transmission end of the cutting adjustment end follower module 6 or the uncut feed end adjustment module 7, the radial deviation surface monitoring unit 23 and the axial offset surface monitoring unit 24 are used to sense the dynamic offset generated when the profile is rotated and cut, and the offset correction callback unit 22 corrects the offset error generated after the profile is rotated as monitored by the radial deviation surface monitoring unit 23 or the axial offset surface monitoring unit 24 according to the dynamic offset.

[0019] The present invention aims to solve the problem that the rotating end of the cut part and the cutting end of the uncut part are non-coordinated flipping, which easily causes radial and axial dynamic offsets in the clamping angle of the profile, resulting in errors in the profile transmission rotation angle during subsequent cutting, which requires manual approval and reset operation. In order to solve this problem, the present invention sets the output end through the spacing control group 3, the cutting dynamic offset monitoring module 2, the PLC control module 5, the cut adjustment end follower module 6 and the uncut feed end adjustment module 7, wherein the output end is used as the conveying limit end after the profile is cut through the spacing control group 3, and the cutting dynamic offset monitoring module 2 is used to monitor the dynamic offset generated during the rotation cutting of the profile, and correct the error generated by the dynamic offset.

[0020] In an optional implementation of the present embodiment, the output end passage spacing control group 3 includes a cut end assembly platform 31, a cut passage spacing adaptation adjustment part 32 and a forward output reserved frame 33, the cut passage spacing adaptation adjustment part 32 is fixedly connected to the forward output reserved frame 33, the cut end assembly platform 31 is rotatably connected to the cut passage spacing adaptation adjustment part 32, the cut passage spacing adaptation adjustment part 32 is used to adjust the passage spacing of the profile during output, so that the profile can be output at the original angle after cutting the adjustment angle, and the forward output reserved frame 33 reserves a through groove for leading out the cut part of the profile.

[0021] In this embodiment, the cut end assembly table 31 serves as the assembly end of the cutting angle dynamic connection part 21, wherein the cutting angle dynamic connection part 21 in one group of the cutting dynamic offset monitoring modules 2 can be rotated and debugged along the inner side of the cut end assembly table 31 by driving the cut end adjustment end follower module 6, and the cutting angle dynamic connection part 21 in another group of the cutting dynamic offset monitoring modules 2 can be rotated and debugged along the inner side of the cutting machine main frame 1 by driving the uncut feed end adjustment module 7. Among them, the cut end adjustment end follower module 6 and the uncut feed end adjustment module 7 can be pre-programmed with a synchronous coordinated motion mode through the PLC control module 5, and the PLC control module 5 can also independently send a driving command to the cut end adjustment end follower module 6 or the uncut feed end adjustment module 7. Among them, the cut and passed spacing adaptation adjustment part 32 is composed of an assembly frame and an adjustable width limiting mechanism. The width of the profile is set by the width limiting mechanism set in the cut and passed spacing adaptation adjustment part 32, so that the profile can maintain the original angle after the cutting and debugging angle, and be output to the next process through the width limiting mechanism of the cut and passed spacing adaptation adjustment part 32 and the forward output reserved frame 33, thereby ensuring that the transmission angle of the profile after cutting still maintains the original angle.

[0022] The laser cutting component 4 is provided with a start-stop execution unit 41, which is connected to the radial deviation surface monitoring unit 23 and the axial deviation surface monitoring unit 24 by signal. After the laser cutting component 4 stops cutting operation, the start-stop execution unit 41 sends a stop cutting signal to the radial deviation surface monitoring unit 23 and the axial deviation surface monitoring unit 24, thereby controlling the radial deviation surface monitoring unit 23 and the axial deviation surface monitoring unit 24 to start monitoring the dynamic offset generated during the rotational cutting of the profile.

[0023] In this embodiment, by setting the start-stop execution unit 41 to trigger the monitoring signals of the radial deviation surface monitoring unit 23 and the axial deviation surface monitoring unit 24, the radial deviation surface monitoring unit 23 and the axial deviation surface monitoring unit 24 only monitor the offset after the cutting action stops, thereby avoiding the radial deviation surface monitoring unit 23 and the axial deviation surface monitoring unit 24 still maintaining state monitoring when the cutting profile rotates, causing monitoring data errors. Among them, the radial deviation surface monitoring unit 23 and the axial deviation surface monitoring unit 24 are both arranged at the transmission end of the offset correction callback unit 22. The radial deviation surface monitoring unit 23 is composed of a profile clamp, a pressure sensor arranged on the clamping surface of the clamp, and an eddy current sensor. The offset correction callback unit 22 is used to debug the clamping rotation angle of the profile clamp in the radial deviation surface monitoring unit 23 and the longitudinal and lateral positions of the profile holder. When the radial deviation surface monitoring unit 23 is operating, it confirms through the pressure sensor that the current profile clamp has completed the fixation of the profile, and measures the static and dynamic relative displacement changes between the profile and the end face of the probe by the pressure contact surface feedback of the pressure sensor and the eddy current sensor, and then obtains the radial dynamic offset. The signal is then received by the PLC control module 5, and the offset correction callback unit 22 is controlled by the PLC control module 5 to adjust the clamping position of the inner profile clamp of the radial deviation surface monitoring unit 23, so as to correct the radial offset error. The axial offset surface monitoring unit 24 is composed of a displacement measuring sensor and a gyroscope sensor, which are both installed at the profile clamping position of the radial deviation surface monitoring unit 23. The displacement measuring sensor and the gyroscope sensor are used by the radial deviation surface monitoring unit 23 to monitor the radial offset of the current profile clamp, verify the axial position change of the current profile clamp, and then determine whether the profile has an axial offset error. After the offset error occurs, the offset correction callback unit 22 is controlled by the PLC control module 5 to adjust the rotation angle of the inner profile clamp of the radial deviation surface monitoring unit 23.

[0024] A start-stop execution unit 41 is arranged on the top of the laser cutting component 4, and a cut end delivery progress monitoring unit 25 is arranged on the top of the cutting angle dynamic connection part 21. The cut end delivery progress monitoring unit 25 is connected to the start-stop execution unit 41 signal. The cut end delivery progress monitoring unit 25 is used to monitor whether the cut part of the profile has completely crossed the forward output reserved frame 33 and was transported to the next process, and send an operation signal to the start-stop execution unit 41 after the cut part of the profile has completely crossed the forward output reserved frame 33.

[0025] In this embodiment, after the progress monitoring unit 25 of the cut end obtains the completion signal of the current single cutting, it monitors whether the cut part of the profile is completely transported across the forward output reserved frame 33 to the next process. After the progress monitoring unit 25 of the cut end obtains the profile that has completed the single cutting and is transported across the forward output reserved frame 33, it sends an intermediate control signal to the start-stop execution unit 41, and controls the laser cutting component 4 to stop immediately through the start-stop execution unit 41, so that the laser cutting component 4 is in a non-operating state. At this time, the PLC control module 5 sends a monitoring start signal to the radial deviation surface monitoring unit 23 and the axial deviation surface monitoring unit 24, so that the radial deviation surface monitoring unit 23 and the axial deviation surface monitoring unit 24 sense the dynamic offset generated during the rotation cutting of the profile, and correct the offset error generated after the rotation of the profile monitored by the radial deviation surface monitoring unit 23 or the axial deviation surface monitoring unit 24 according to the dynamic offset through the offset correction callback unit 22, so as to realize the continuous operation of the operation process.

[0026] A loading end transmission connection platform 8 is arranged at one end of the cutting machine main frame 1 away from the output end through the spacing control group 3, and a feed specification calibration module 81 is arranged on the inner side of the loading end transmission connection platform 8. The loading end transmission connection platform 8 is connected to the external profile drive transmission mechanism, and the feed specification calibration module 81 is used for sliding guidance before the profile is input to the cutting position of the laser cutting component 4.

[0027] In this embodiment, the feed specification calibration module 81 is connected to an external propulsion mechanism, which is used to adjust the rotation angle of the profile before it is cut and fed in, and then calibrate the transmission angle of the profile when it enters the cutting position of the laser cutting component 4, so that the profile can be stably transported to the bottom of the laser cutting component 4, ensuring that the laser cutting surface is flat and uniform.

[0028] The working principle of the present invention is as follows: before starting laser cutting, the current profile specification is input into the PLC control module 5, and a control signal is sent to the cut adjustment end follower module 6, the uncut feed end adjustment module 7, the feed specification calibration module 81 and the cut spacing adaptation adjustment unit 32 through the PLC control module 5, so as to set the rotation parameters of the cut adjustment end follower module 6 and the uncut feed end adjustment module 7 during profile cutting, and adjust the rotation angle of the profile when it is initially fed in through the feed specification calibration module 81 before the profile starts to be cut and fed in, so that it is forwardly conveyed to the bottom of the laser cutting component 4, and the cut spacing adaptation adjustment unit 32 adjusts the conveying angle after cutting according to the current profile specification. After the adjustment is completed, the profile is fed into the bottom of the laser cutting component 4 through the external feeding and pushing mechanism, and the profile is fixed by the profile clamp in the radial deviation surface monitoring unit 23, and then the laser cutting component 4 performs the cutting operation. After the single cutting surface of the profile is processed, the cutting angle dynamic connection part 21 is driven to rotate by the cut adjustment end follower module 6 and the uncut feeding end adjustment module 7, so that the radial deviation surface monitoring unit 23 on the inner side of the cutting angle dynamic connection part 21 starts to rotate, until all surfaces of the profile are cut, the external feeding and pushing mechanism pushes the current cut profile segment to the inner side of the cut spacing adaptation adjustment part 32, so that the cut profile segment is sent to the next process through the forward output reserved frame 33. At this time, the progress monitoring unit 23 is sent out through the cut end. After the measuring unit 25 obtains that the profile that has been cut once has been transported across the forward output reserved frame 33, it sends an intermediate control signal to the start-stop execution unit 41, and controls the laser cutting component 4 to stop immediately through the start-stop execution unit 41, so that the laser cutting component 4 is in a non-operating state. At this time, the PLC control module 5 sends a monitoring start signal to the radial deviation surface monitoring unit 23 and the axial deviation surface monitoring unit 24, so that the radial deviation surface monitoring unit 23 and the axial deviation surface monitoring unit 24 sense the dynamic offset generated during the rotational cutting of the profile, and correct the offset error generated after the rotation of the profile monitored by the radial deviation surface monitoring unit 23 or the axial deviation surface monitoring unit 24 according to the dynamic offset through the offset correction callback unit 22, so as to realize the continuous operation of the operation process.

[0029] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
