[0028] Example 1:

[0029] To enable cutting exhaust pipes of different lengths, please refer to [link / reference]. Figure 1 and Figure 2 This utility model provides a technical solution: a laser cutting device for processing exhaust pipes, including a cutting table 1, a support leg 2 fixedly installed at the bottom of the cutting table 1, a moving adjustment mechanism 3 extending from the bottom to the top of the cutting table 1, and a rotating cutting mechanism 4 installed at the top of the moving adjustment mechanism 3.

[0030] The moving adjustment mechanism 3 includes a first motor 31, which is fixedly installed at the bottom of the cutting table 1 near the left end. A bidirectional screw 32 is fixedly installed at the output end of the first motor 31. A center block 33 is fixedly installed at the middle position of the bottom of the cutting table 1. A support block 34 is fixedly installed at the bottom of the cutting table 1 near the right end. A sliding table 35 is slidably installed from the inside to the outside of the cutting table 1 to facilitate adjusting the position of the sliding table 35 according to the length of the exhaust pipe.

[0031] Furthermore, two sliding tables 35 are provided, and the two sliding tables 35 are symmetrically threaded on the outside of the two ends of the bidirectional screw 32 with opposite thread directions around the center line of the front of the cutting table 1, so as to facilitate the synchronous reverse sliding of the two sliding tables 35.

[0032] Furthermore, a through hole is provided at the center of the central block 33, and a bidirectional screw 32 is rotatably installed inside the through hole. The end of the bidirectional screw 32 away from the first motor 31 is rotatably installed on the left side of the support block 34, so that the bidirectional screw 32 can be supported and rotated.

[0033] Example 2:

[0034] To achieve clamping and rotary cutting of exhaust pipes of different diameters, please refer to [link / reference needed]. Figures 3-5 Furthermore, in conjunction with Embodiment 1, the rotary cutting mechanism 4 includes a pressing component 41, a rotating component 42, and a cutting component 43. The pressing component 41 is disposed on the top of the sliding table 35, the rotating component 42 is disposed on the top of the sliding table 35, and the cutting component 43 is disposed outside the pressing component 41.

[0035] Furthermore, the pressing assembly 41 includes a mounting bracket 411, which is fixedly mounted on the top of the sliding table 35. A second motor 412 is fixedly mounted on the top of the mounting bracket 411, and a trapezoidal screw 413 is fixedly mounted on the output end of the second motor 412. A sliding plate 414 is slidably mounted inside the mounting bracket 411 and rotatably mounted on the front side. A pressing roller 415 is rotatably mounted on the bottom of the sliding plate 414 to facilitate pressing and fixing the exhaust pipe.

[0036] Furthermore, threaded holes are provided at the corresponding positions of the sliding plate 414 and the trapezoidal screw 413, and the sliding plate 414 is threadedly installed in the threaded holes, so that the trapezoidal screw 413 can drive the sliding plate 414 to slide.

[0037] Furthermore, the rotating assembly 42 includes a third motor 421, which is fixedly mounted on the outside of the mounting frame 411. A first synchronous pulley 422 is fixedly mounted on the output end of the third motor 421. A support frame 423 is fixedly mounted on the top of the sliding table 35. Two support rollers 424 are rotatably mounted on the top of the support frame 423. A second synchronous pulley 425 is fixedly mounted on the outside of the support roller 424 near the back. A synchronous belt 426 is installed between the first synchronous pulley 422 and the second synchronous pulley 425 to facilitate driving the exhaust pipe to rotate and cut.

[0038] Furthermore, the cutting assembly 43 includes a connecting frame 431, which is fixedly installed on the top of the left sliding plate 414. An electric telescopic rod 432 is fixedly installed on the top of the end of the connecting frame 431 away from the sliding plate 414. A laser cutting head 433 is fixedly installed on one end of the electric telescopic rod 432 that passes through the connecting frame 431, so as to facilitate the adjustment of the distance between the laser cutting head 433 and the exhaust pipe.

[0039] In actual operation, when this device is used, firstly, the first motor 31 drives the bidirectional screw 32 to rotate, so that the bidirectional screw 32 drives the two sliding tables 35 to slide laterally, so that the two sliding tables 35 are adjusted to a suitable position according to the length of the exhaust pipe, and the left sliding table 35 drives the cutting head to move laterally.

[0040] The exhaust pipe is then placed on the support roller 424, with the cutting position directly below the laser cutting head 433. The second motor 412 drives the trapezoidal screw 413 to rotate, causing the sliding plate 414 to slide downwards. This causes the sliding plate 414 to drive the pressure roller 415 downwards, allowing the pressure roller 415 to work with the support roller 424 to press and fix the exhaust pipe. The third motor 421 then drives the first synchronous pulley 422 to rotate, which in turn drives the second synchronous pulley 425 to rotate via the synchronous belt 426. This causes the second synchronous pulley 425 to rotate the support roller 424, which in turn rotates the exhaust pipe. Finally, the electric telescopic rod 432 moves the laser cutting head 433 downwards, allowing it to cut the exhaust pipe.

[0041] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
