Embodiment 4

[0039] Reference Figure 1-13 The difference between this embodiment and embodiment 2 is that the pipe fixing seat 5 includes a mounting frame 501, and a horizontal rotating shaft 502 is installed on the mounting frame 501. The horizontal rotating shaft 502 is driven to rotate by a second rotating motor 503. A pipe clamping mechanism 6 is fixed to one end of the horizontal rotating shaft 502. The horizontal rotating shaft 502 can be driven to rotate by the second rotating motor 503, and then the pipe clamping mechanism 6 can be driven to reverse 180 degrees as a whole, so that the pipe after cutting and grinding at the top of the pipe clamping mechanism 6 is flipped to the bottom of the pipe clamping mechanism 6, and then the processed pipe can be put down. Example 5

[0040] Reference Figure 1-13 The difference between this embodiment and embodiment 1 is that the laser cutting machine 2 includes a cutting bracket 201 , on which a horizontal moving block 203 and a vertical moving block 207 are mounted, and on which a laser cutting head 210 is fixed.

[0041] A horizontal guide rod 202 is fixed on the cutting bracket 201, and the horizontal guide rod 202 passes through the horizontal moving block 203 through the horizontal guide hole. A horizontal screw rod 204 is also rotatably mounted on the cutting bracket 201, and the horizontal screw rod 204 passes through the horizontal moving block 203 through a thread, and the horizontal screw rod 204 is driven to rotate by a horizontal driving motor 205;

[0042] The horizontal drive motor 205 can drive the horizontal lead screw 204 to rotate, thereby driving the horizontal moving block 203 to move horizontally, thereby driving the laser cutting head 210 to move horizontally, and thus driving the laser cutting head 210 to cut the pipeline.

[0043] A vertical guide rod 206 is fixed on the horizontal moving block 203, and the vertical guide rod 206 penetrates the vertical moving block 207 through a vertical guide hole. A vertical screw rod 208 is also rotatably mounted on the horizontal moving block 203, and the vertical screw rod 208 penetrates the vertical moving block 207 through a thread, and the vertical screw rod 208 is driven to rotate by a vertical driving motor 209;

[0044] The vertical drive motor 209 can drive the vertical screw 208 to rotate, which in turn can drive the vertical moving block 207 to move vertically, which in turn can drive the laser cutting head 210 to move up and down, thereby adjusting the distance between the laser cutting head 210 and the pipe. During the cutting process, the laser cutting head 210 can approach the pipe and be retracted after the cutting is completed. It can be adaptively adjusted according to the size and position of the pipe to be cut, and has a wider range of usage scenarios. Example 6

[0045] Reference Figure 1-13, the difference between this embodiment and embodiment 4 is that the pipe clamping mechanism 6 includes a clamping box 601, both sides of the clamping box 601 are provided with U-shaped clamping rods 602, one end of the U-shaped clamping rod 602 extends to the inside of the clamping box 601 and is fixed with a spur rack 605, the spur rack 605 is movably installed in the clamping box 601 through a guide rail, the other end of the U-shaped clamping rod 602 is fixed with an arc-shaped clamping plate 603, an arc-shaped support plate 604 is fixed between the two U-shaped clamping rods 602 on the pipe clamping mechanism 6, a first return spring 606 is installed between the spur rack 605 and the inner wall of the clamping box 601, a driving shaft 607 is provided between the two spur racks 605 in the clamping box 601, a first transmission gear 608 is fixed to the outside of the driving shaft 607, and the two spur racks 605 are meshed with the first transmission gear 608;

[0046] When the driving shaft 607 rotates, it can drive the first transmission gear 608 to rotate, and then drive the two spur racks 605 to move away from each other through meshing, and then drive the two arc-shaped clamping plates 603 to move away from each other. When installing the pipeline, place the pipeline on the arc-shaped support plate 604, and the elastic force of the first return spring 606 will push the two arc-shaped clamping plates 603 closer to each other to clamp and fix the pipeline.

[0047] Among them, one end of the driving shaft 607 extends to the outside of the clamping box 601 and fixes the second transmission gear 609, and the double-sided gear ring 507 is rotatably installed on the outside of the horizontal shaft 502, and the inner ring of the double-sided gear ring 507 is meshed with the second transmission gear 609. A collection box 4 is also placed below the support platform 1, and the bottom end of the support platform 1 is located just above the collection box 4 and is fixed with an arc-shaped rack 113;

[0048] When the pipe after cutting and polishing is transported to the top of the collection box 4, the second rotating motor 503 drives the pipe clamping mechanism 6 to reverse 180 degrees as a whole, so that the pipe at the top of the pipe clamping mechanism 6 is flipped to the bottom of the pipe clamping mechanism 6. During the movement, the double-sided gear ring 507 will move to the position of the arc-shaped rack 113, and the arc-shaped rack 113 will engage with the outer ring of the double-sided gear ring 507, thereby driving the double-sided gear ring 507 to rotate. Since the inner ring of the double-sided gear ring 507 is engaged with the second transmission gear 609, it can drive the driving shaft 607, thereby driving the two arc-shaped clamping plates 603 to separate from each other, so that the pipe can be automatically lowered to this position and fall into the inside of the collection box 4. When the arc-shaped rack 113 is disengaged from the double-sided gear ring 507, the first reset spring 606 will push the arc-shaped clamping plate 603 to move and reset. Example 7

[0049] Reference Figure 1-13The difference between this embodiment and embodiment 6 is that a collar 510 is movably installed on the outside of the horizontal rotating shaft 502, located on the side of the double-sided gear ring 507 away from the clamping box 601. The collar 510 can slide horizontally along the horizontal rotating shaft 502 and cannot rotate relative to the horizontal rotating shaft 502. A second return spring 508 is fixed to the outside of the horizontal rotating shaft 502, located on the side of the collar 510 away from the double-sided gear ring 507. A locking pin 505 is fixed to one side of the collar 510. A positioning hole is provided on the double-sided gear ring 507. When the locking pin 505 is moved by the elastic force of the second return spring 508 and inserted into the positioning hole, the double-sided gear ring 507 cannot rotate relative to the horizontal rotating shaft 502. At this time, the distance between the two arc-shaped clamping plates 603 will not continue to change, which can ensure that the arc-shaped clamping plates 603 are close to each other. After the pipe is clamped, it is locked, and the pipe will not deviate or shake during the cutting and grinding process, which improves the processing yield rate. An offset guide rod 506 is also fixed on the locking pin 505, and a limiting guide groove 107 is also fixed at the bottom end of the support platform 1 at the position of the arc rack 112. Before the arc rack 113 engages with the double-sided gear ring 507, the offset guide rod 506 will first move to the limiting guide groove 107. When the offset guide rod 506 moves along the limiting guide groove 107, it will drive the locking pin 505 to separate from the positioning hole, thereby releasing the lock on the double-sided gear ring 507 and ensuring that the double-sided gear ring 507 can rotate. When the pipe is lowered, the offset guide rod 506 is disengaged from the limiting guide groove 107, and the locking pin 505 is automatically inserted back into the positioning hole under the elastic force of the second reset spring 508.

[0050] A hanging rod 504 is fixed to the side of the ring 510 away from the locking pin 505, and a manual hook 509 is rotatably installed on the mounting frame 501. When installing the pipeline, the locking pin 505 can be manually separated from the positioning hole, and the hanging rod 504 can be hooked by the manual hook 509. At this time, the spacing lock between the two arc-shaped clamping plates 603 is released, and the pipeline can be installed at this time. After the installation is completed, the manual hook 509 is moved to release the movement of the hanging rod 504, thereby completing the locking of the pipeline.
