Description

All parts, assemblies, components and assemblies used in cars are collectively referred to as auto parts. Auto parts pipes require a variety of processing methods, including casting, forging, stamping, machining, laser cutting and pipe cutting technology. When laser cutting is performed, the pipes will be cut by a laser cutting machine.

[0003] However, when the laser cutting machine cuts overly long parts or pipes with poor rigidity, it is affected by gravity deformation and the centrifugal force of the three-jaw chuck rotation, resulting in poor stability during cutting, which affects the cutting quality; at the same time, a large amount of waste slag is generated during cutting, and the waste slag generated during cutting will slide along the blanking plate to the collection frame.

A first tension spring 405 is fixedly connected between the anti-drop plate 403 and the mounting frame 401, and the anti-drop plate 403 is fixed by a limiting structure 6. A guide column 404 is fixedly connected to the bottom of the mounting frame 401, and the anti-drop plate 403 is slidably connected to the guide column 404.

[0036] Specifically, Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Fig.10As shown, the limiting structure 6 includes a sleeve 601 fixedly connected to the front of the laser cutting machine body 1 and a limiting block 602 slidably connected to the sleeve 601, the limiting block 602 is engaged with the anti-fall plate 403, a fixing rod 603 is fixedly connected to the limiting block 602, a driving block 605 is fixedly connected to the fixing rod 603, a second tension spring 604 is fixedly connected between the fixing rod 603 and the sleeve 601, a collecting structure 5 is provided at the bottom of the installation frame 401, and the collecting structure 5 includes a first collecting box 501 slidably connected to the bottom of the installation frame 401 and a Two positioning blocks 502, the first collection box 501 is slidably connected to the positioning blocks 502, one of the positioning blocks 502 is threadedly connected with a knob 503, the knob 503 conflicts with the first collection box 501, the first collection box 501 is fixedly connected with a fixing block 504, the fixing block 504 is fixedly connected with a fixing shaft 505, the fixing shaft 505 is rotatably connected with a roller 506, the laser cutting machine body 1 is slidably connected with a second collection box 507, at this time, the fixing wheel 807 no longer clamps the pipe, the pipe will roll down the grid 402 into the first collection box 501, the setting of the grid 402 is convenient for The waste residue generated during processing falls into the second collection box 507. At the same time, the setting of the first collection box 501 is convenient for collecting the processed pipes. When the first collection box 501 needs to be removed from the installation frame 401, by turning the knob 503, the knob 503 no longer fixes the first collection box 501, and then the first collection box 501 is pulled. The first collection box 501 will cause the roller 506 to conflict with the inclined surface of the driving block 605, which will cause the driving block 605 to drive the fixing rod 603 to move to the right.

When a section of the pipe needs to be cut after processing, the laser cutter 7 04 cooperates with the rotation of the pipe to cut it, and then starts the third hydraulic rod 811. When the telescopic end of the third hydraulic rod 811 is extended, it drives the connecting frame 803 to move downward. When the center of the pipe moves to align with the center position of the retaining ring 902, the fourth hydraulic rod 904 is started, so that the telescopic end of the fourth hydraulic rod 904 drives the vertical rod 903 to move to the left. The vertical rod 903 drives the sliding pipe 901 to move, so that the sliding pipe 901 is inserted into the processed pipe fitting, and then the air pump 906 is started. When the air pump 906 is in operation, the air flow enters the sliding pipe 901 through the connecting pipe 905, and then the waste residue in the pipe fitting is blown out to prevent the waste residue from remaining in the pipe fitting and affecting the subsequent processing;

[0041] At this time, the fixed wheel 807 no longer clamps the pipe, and the pipe will roll down the grille 402 into the first collection box 501. The setting of the grille 402 is convenient for dropping the waste slag generated during processing into the second collection box 507. At the same time, the setting of the first collection box 501 is convenient for collecting the processed pipes. When the first collection box 501 needs to be removed from the installation frame 401, the knob 503 is turned, and the knob 503 no longer fixes the first collection box 501. The first collection box 501 is pulled, and the first collection box 501 causes the roller 506 to conflict with the inclined surface of the driving block 605, which causes the driving block 605 to drive the fixing rod 603 to move to the right. When the fixing rod 603 moves to the right, the second tension spring 604 extends. At the same time, the fixing rod 603 will drive the limit block 602 to no longer engage with the anti-fall plate 403. At this time, the anti-fall plate 403 moves upward under the action of the first tension spring 405, and the anti-fall plate 403 moves more smoothly through the guide column 404 when sliding. At this time, when replacing another first collecting box 501, the processed pipe will be blocked by the anti-fall plate 403 and will not fall to the ground, thereby improving the collection efficiency. After the installation of the other first collecting box 501 is completed, it is only necessary to press the anti-fall plate 403 downward to make the anti-fall plate 403 contact the inclined surface of the limit block 602. When it moves to a certain position, the limit block 602 will limit the anti-fall plate 403 and fix the anti-fall plate 403 to prevent the anti-fall plate 403 from self-slipping and improve stability.
