[0029] Reference Figure 1 to Figure 7 The fiber laser cutting machine of the present invention is implemented as follows:

The chuck device 100 comprises a front chuck and a rear chuck arranged at the front and rear sides of the frame 1000. The front chuck is slidably connected to the frame 1000. The front chuck is used to push the pipe to be cut to the laser cutting head for cutting. In order to reduce the swing of the pipe between the front chuck and the laser cutting head and reduce the processing error, several groups are arranged along the length direction of the frame 1000. The clamping device 200 comprises a deviation correction component 210 and a lifting component 220.

[0032] Taking control accuracy into consideration, a first rack-and-pinion transmission mechanism 400 is provided on the frame 1000. The first rack-and-pinion transmission mechanism 400 is arranged in one-to-one correspondence with the clamping device 200. The first rack-and-pinion transmission mechanism 400 includes a first rotating rod 410, a first gear 420 and a second servo motor. The first rotating rod 410 is arranged along the length direction of the frame 1000. The first rotating rod 410 is fixedly connected to the output shaft of the second servo motor. The first gear 420 is fixedly penetrated on the first rotating rod 410. A slider is protruded on the inner side surface of the frame 1000. The first rack plate 430 is provided with a The groove enables the first rack plate 430 to be slidably connected to the frame 1000 in the vertical direction, the first rack plate 430 is meshed with the first gear 420, a baffle 440 extending in the front-to-back direction is provided on the rack plate, a pressure rod 450 extending in the left-to-right direction is provided below the baffle 440, and the pressure rod 450 is fixed on the support rod 221, and the baffle 440 and the pressure rod 450 can be pressed against each other, so that the second servo motor of the first gear rack transmission mechanism 400 and the first lifting cylinder 222 of the lifting assembly 220 cooperate with each other, thereby realizing precise control of the up and down lifting of the deviation correction assembly 210. In order to facilitate installation, a plurality of partitions are arranged at intervals in the front and back of the frame 1000, a group of clamping devices 200 and the first gear rack transmission mechanism 400 are arranged between the two partitions, the lower end of the support rod 221 is hinged to the corresponding partition, and the first rotating rod 410 is passed through the partition.

[0033] In some embodiments, the correction component 210 is connected to the frame 1000 via a sliding connection structure 500, and the sliding connection structure 500 includes a guide pin 510 and a guide groove 520. The guide pin 510 is fixedly arranged on the lower side of the first mounting seat 211, and the guide groove 520 is arranged on the inner side surface of the frame 1000 corresponding to the guide pin 510. The guide groove 520 extends along the length direction of the frame 1000, and the guide pin 510 is slidably arranged in the guide groove 520.

[0034] Furthermore, the guide groove 520 includes a first segmented groove and a second segmented groove which are connected to each other, the first segmented groove and the second segmented groove are both arranged to be horizontally inclined, the first segmented groove is arranged on the upper side of the second segmented groove, the horizontal inclination angle of the first segmented groove is greater than the horizontal inclination angle of the second segmented groove, the first segmented groove and the second segmented groove are connected by a smooth transition of an arc surface, and the correction component 210 has an unfolded state and a folded state which can be converted to each other; when the correction component 210 is in the unfolded state, the guide pin 510 can be slidably located in the first segmented groove, and the clamping roller 213 remains vertical; when the correction component 210 is in the folded state, the guide pin 510 can be slidably located in the second segmented groove In the inside, the clamping roller 213 is folded toward the support rod 221. By setting the guide groove 520 in sections, the correction assembly 210 has an unfolded state and a folded state that can be converted to each other. When the correction assembly 210 is in the unfolded state, the guide pin 510 slides in the first segmented groove to achieve fine adjustment of the correction assembly 210 up and down. The arc surface transition between the first segmented groove and the second segmented groove facilitates the correction assembly 210 to be converted to the folded state. When the correction assembly 210 is in the unfolded state, the guide pin 510 slides in the second segmented groove to achieve coarse adjustment of the correction assembly 210 up and down, which is convenient for reserving the sliding space of the chuck device 100 above the frame 1000. In order to reduce the wear between the guide pin 510 and the guide groove 520, the guide pin 510 is provided with a rolling member at one end close to the guide groove 520, and the rolling member is rotatably engaged in the guide groove 520. The sliding of the guide pin 510 in the guide groove 520 is achieved by the rolling member.

[0035] In some embodiments, reference Figure 7A material unloading assembly 600 is provided on the rear side of the frame 1000. The material unloading assembly 600 includes a material unloading base 610 and a material unloading plate 620. The material unloading plate 620 is provided on the top of the material unloading base 610. A plurality of mounting grooves are provided on the material unloading plate 620 at intervals in front and rear. Rollers 640 are embedded in the mounting grooves one by one, and the rollers 640 partially protrude from the upper surface of the material unloading plate 620. The rollers 640 are used to support the cut pipes. The distance between the rollers 640 and the material unloading plate 620 is small, which is conducive to material unloading. At the same time, for the pipes with smaller lengths, the upper surface of the material unloading plate 620 between the two rollers 640 can also play a certain supporting role.A second lifting cylinder 630 and a second gear rack transmission mechanism 700 are provided between the unloading base 610 and the unloading plate 620. The second lifting cylinder 630 and the second gear rack transmission mechanism 700 are electrically connected to the control system 300. The second gear rack transmission mechanism 700 corresponds to the second lifting cylinder 630 one by one. The second gear rack transmission mechanism 700 includes a second rotating rod 710, a second gear 720, a second rack plate 730, and a third servo motor. The second rotating rod 710 extends in the front-to-back direction. The second rotating rod 710 is fixedly connected to the output shaft of the third servo motor. The second gear 720 is fixedly penetrated in On the second rotating rod 710, the second rack plate 730 is meshed with the second gear 720, and the second rack plate 730 is slidably connected to the inner side of the unloading base 610 in the vertical direction. The sliding connection between the second rack plate 730 and the unloading base 610 is the same as the sliding connection between the first rack plate 430 and the frame 1000. The movement of the second gear 720 is controlled by the third servo motor to adjust the up and down movement of the second rack plate 730. The upper end surface of the second rack plate 730 is hinged to the left side of the unloading plate 620, and the lower end of the second rack plate 730 is hinged to one end of the jacking cylinder, and the other end of the jacking cylinder is hinged. On the right side of the blanking plate 620, the blanking plate 620 is driven by the second lifting cylinder 630, so that the blanking plate 620 can be rotated around the blanking base 610 to achieve the adjustment of different angles of the blanking plate 620. At the same time, the blanking plate 620 can be lifted up and down with the second rack plate 730, so as to adjust the height of the blanking plate 620. The second lifting cylinder 630 and the second gear rack transmission mechanism 700 cooperate to adjust the height and angle according to the rotation trajectory of the pipes with different cross-sectional shapes after cutting, so that the support roller 223 on the blanking plate 620 always keeps in contact with the surface of the pipe, ensuring that the pipe The rotation center is always located on the same horizontal line, which avoids the pipe from swinging and reduces the processing deviation of cutting. At the same time, after the blanking plate 620 is rotated, the pipe can be automatically unloaded. When in use, when the pipe is being cut, the second lifting cylinder 630 lifts the blanking plate 620 to a horizontal level, and slightly adjusts the angle and height of the blanking plate 620 according to the cross-sectional shape of the cut pipe. When the pipe cutting is completed, the second lifting cylinder 630 adjusts the blanking plate 620 to an inclined state. A receiving box 800 is provided on the right side of the blanking base 610, and the pipe is dropped into the receiving box 800 along the inclined blanking plate 620 to realize automatic blanking.

[0036] It is understandable that a clamping device 200 can be provided on the blanking base 610, and the clamping device 200 is provided between the blanking plate 620 and the laser cutting head to effectively clamp the cut pipe and reduce the rolling of the cut pipe. In addition, in order to recycle the waste from pipe cutting, a waste collection box is provided under the laser cutting head, and the waste collection box is connected to a dust collecting device to absorb the dust generated by the laser head.

[0037] When in use, the rotation trajectory path diagram of various special-shaped pipes to be cut is input into the control system 300 in advance, and the chuck device 100, the clamping device 200, the laser cutting head, the first gear rack transmission mechanism 400, the second lifting cylinder 630, and the second gear rack transmission mechanism 700 are all electrically connected to the control system 300. The pipe is clamped by the chuck device 100 and rotated toward the laser cutting head for cutting. During the rotation and transportation of the pipe, multiple groups of clamping devices 200 are set to avoid the pipe from shaking up and down and left and right, avoid deviation values ​​between the pipe and the rotation center of the chuck device 100, and reduce the processing deviation of pipe cutting. First, the deflection-correcting assembly 210 is in a folded state folded toward the support rod 221, and the lifting cylinder is used to lift the lifting assembly 220 upward, and the guide pin 510 connected to the deflection-correcting assembly 210 slides upward in the second segmented groove, and the deflection-correcting assembly 210 rises with the lifting assembly 220; when the guide pin 510 slides to the transition point of the arc surface between the first segmented groove and the second segmented groove, the deflection-correcting assembly 210 is converted from the folded state to the unfolded state; when the deflection-correcting assembly 210 is in the unfolded state, the guide pin 510 slides in the first segmented groove, and the clamping roller 21 of the deflection-correcting assembly 210 3 can always remain vertical, and the rotation angle of the rotating member 212 can be accurately controlled by controlling the first servo motor to adjust the clamping space according to the cross-sectional shape and diameter of the pipe. At this time, the first gear rack transmission mechanism 400 starts to operate, and the second servo motor drives the rotating rod to drive the first gear 420 to rotate, so that the first rack plate 430 slides up and down, so that the baffle plate 440 connected to the first rack plate 430 and the pressing rod 450 connected to the support rod 221 are pressed against each other, so that the second servo motor of the first gear rack transmission mechanism 400 and the first servo motor of the lifting assembly 220 are pressed against each other. The lifting cylinder 222 cooperates with each other to achieve precise control of the up and down lifting of the correction component 210.
