Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0030] Please refer to Figures 1-5, the utility model is a pipe fitting positioning structure for a laser pipe cutting machine, which includes a pipe fitting body 3. An installation frame 6 is arranged outside the pipe fitting body 3. The right side of the pipe fitting body 3 is open. Cylinders 602 are arranged in a circumferential array on both the left and right sides inside the installation frame 6, which are used to drive the universal balls 602a to clamp or release the pipe fitting body 3. Moving blocks 5 are symmetrically arranged in the front and back on the left side inside the installation frame 6. A conveying motor 501 is fixed on the upper wall of the moving block 5. A rubber sleeve 2 is arranged corresponding to the inside below the conveying motor 501. When the conveying motor 501 works, it drives the rubber sleeve 2 to rotate. Since the rubber sleeve 2 is in contact with the pipe fitting body 3, the pipe fitting body 3 is driven to move. A gear ring 702 is fixed on the left wall of the installation frame 6. A gear 401a is meshed and connected in front of the gear ring 702. A motor 401 is arranged on the left side of the gear 401a. When the motor 401 works, it drives the gear 401a to rotate, thereby driving the gear ring 702 to rotate. Since the gear ring 702 is fixedly connected to the installation frame 6, the installation frame 6 also rotates, and finally the pipe fitting body 3 rotates;

[0031] Specifically, the outer end of the cylinder 602 is fixedly connected to the installation frame 6. The inner end of the cylinder 602 is fixed with a universal ball 602a, and the balls in the universal ball 602a are in contact with the pipe fitting body 3. When the cylinder 602 drives the universal ball 602a to make the balls in the universal ball 602a all contact the pipe fitting body 3, the pipe fitting body 3 can be clamped, and when the balls in the universal ball 602a are separated from the pipe fitting body 3, the pipe fitting body 3 can be removed;

[0032] The moving block 5 is slidably connected to the installation frame 6. When the screw 603a rotates, the moving block 5 and the installation frame 6 can move relative to each other when they are in contact. At this time, the moving block 5 will not rotate. The rubber sleeve 2 is in contact with the pipe fitting body 3. The friction between the rubber sleeve 2 and the pipe fitting body 3 is used to make the rubber sleeve 2 rotate to drive the pipe fitting body 3 to move. An arc-shaped groove is formed on the outer peripheral wall of the rubber sleeve 2 along the circumferential direction of the rubber sleeve 2. A rectangular groove 502 is formed on the moving block 5 corresponding to the position of the rubber sleeve 2, providing an installation space for the installation of the rubber sleeve 2;

[0033] A rotating rod 201 is fixed inside the rubber sleeve 2, and the rotating rod 201 is rotatably connected to the moving block 5 through a bearing. The rotating rod 201 is fixedly connected to the power output shaft of the conveying motor 501. By making the conveying motor 501 work to drive the rotating rod 201 to rotate, the rubber sleeve 2 can be rotated;

[0034] At the position where the moving block 5 is located, a clamping motor 603 is fixed to the front wall of the mounting frame 6. A screw rod 603a is fixed on the power output shaft of the clamping motor 603, and the thread directions on the front and rear sides of the outer peripheral wall of the screw rod 603a are opposite. The screw rod 603a is in threaded connection with the corresponding moving block 5. By driving the screw rod 603a to rotate with the clamping motor 603 working, the two moving blocks 5 approach or move away from each other, realizing the contact or separation between the rubber sleeve 2 and the pipe fitting body 3, achieving the effect of clamping or releasing the pipe fitting body 3;

[0035] An installation ring 7 is fixed to the left wall of the gear ring 702. An installation groove 701 is formed in the outer peripheral wall of the installation ring 7 along the circumferential direction of the installation ring 7. An installation plate 4 is arranged in the installation groove 701, and the installation ring 7 and the installation plate 4 are in clearance fit. When the motor 401 works, the installation ring 7 and the installation plate 4 rotate relative to each other;

[0036] The motor 401 is fixedly connected to the installation plate 4. A through hole 601 is formed in the left wall of the mounting frame 6 corresponding to the position where the installation groove 701 is located for the pipe fitting body 3 to pass through;

[0037] The operation process of this embodiment is as follows: The pipe fitting body 3 is inserted into the interior of the mounting frame 6 from left to right through operation, so that the right end of the pipe fitting body 3 extends out of the mounting frame 6. At this time, the control cylinder 602 is extended to drive the universal ball 602a to move, so that all the balls in the universal ball 602a are in contact with the outer peripheral wall of the pipe fitting body 3. Then, the clamping motor 603 is made to work to drive the screw rod 603a to rotate, so that the two moving blocks 5 approach each other until both rubber sleeves 2 are in contact with the pipe fitting body 3, and then the pipe fitting body 3 can be positioned;

[0038] When moving the pipe fitting body 3, the conveying motor 501 is controlled to work to drive the rotating rod 201 to rotate, so that the rubber sleeve 2 rotates to move the pipe fitting body 3. When rotating the pipe fitting body 3, the motor 401 is made to work to drive the gear 401a and the gear ring 702 to rotate, so that the mounting frame 6 rotates, and finally the pipe fitting body 3 rotates. Embodiment 2

[0039] Please refer to Figure 1 and 6 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but different from the first embodiment: A filter plate 8 is arranged on the upper surface of the mounting frame 6. The filter plate 8 can be an activated carbon filter plate 8. A fan 1 is arranged above the filter plate 8. The airflow generated by the fan 1 carries the smoke through the filter plate 8 to adsorb and filter the smoke;

[0040] Specifically, a limiting boss 604 is fixed to the upper wall of the corresponding mounting frame 6 outside the filter plate 8. The limiting boss 604 is adapted to the filter plate 8 to limit the filter plate 8. A through hole 605 is opened in the upper wall of the mounting frame 6 corresponding to the position of the filter plate 8. A rotating plate 102 is provided on the upper wall of the filter plate 8, and the fan 1 is fixedly connected to the rotating plate 102;

[0041] The rotating plate 102 is rotatably connected to the limiting boss 604 through a hinge, and the hinge is located at the left end of the rotating plate 102. A bolt 102a is provided at the right end of the rotating plate 102, and the bolt 102a is threadedly connected to the mounting frame 6. By loosening the bolt 102a and then operating the rotation of the rotating plate 102, the filter plate 8 can be taken out for replacement;

[0042] Air outlet holes 102b are formed on the surface of the rotating plate 102, and a protective net 101 is fixed to the upper wall of the fan 1. The protective net 101 can be made of a metal material;

[0043] The remaining structures are the same as those in the first embodiment;

[0044] The operation process of this embodiment is as follows: When in use, the fan 1 is operated. When the fan 1 operates, a negative pressure state is formed inside the mounting frame 6. At this time, the smoke generated during cutting passes through the through hole 605, the filter plate 8, and the air outlet holes 102b and is discharged to the outside of the mounting frame 6. When passing through the filter plate 8, the smoke can be adsorbed and filtered to avoid environmental pollution caused by the dispersion of the smoke.
