Description

Technical Field

[0001] The utility model relates to the technical field of cutting mechanisms, in particular to a laser cutting structure for automobile exhaust pipes. Background Art

[0002] Laser cutting of automobile exhaust pipes is an important technology in modern automobile manufacturing. It uses the high energy density and precise control ability of the laser beam to perform efficient and precise cutting on automobile exhaust pipes.

[0003] In the prior art, a Chinese patent with the publication number CN219818440U discloses a laser cutting structure for exhaust pipes, which includes a handheld laser cutting machine. One side of the handheld laser cutting machine is provided with a plug-in slot, and a plug-in block is inserted into the plug-in slot. Connecting rods are fixedly connected to both sides of the plug-in block. Adjusting rods are slidably inserted into both ends of the connecting rod. Two first fastening screws are inserted into one side of the adjusting rod. The bottom end of the adjusting rod is fixedly connected to a rotating plate. A first clamping plate is provided on one side of the rotating plate. A sliding groove is provided on one side of the first clamping plate, and the rotating plate slides in the sliding groove. This patent can adjust the length of the adjusting rod, thereby adjusting the height of the handheld laser cutting machine to be suitable for cutting exhaust pipes of different specifications. Then, by pulling the handheld laser cutting machine to move, the rotating plate slides in the sliding groove, so that the handheld laser cutting machine cuts along the circumference of the exhaust pipe, improving the effect of laser cutting of the exhaust pipe.

[0004] However, the above patent has some deficiencies. In the actual use process, when the above patent cuts the exhaust pipe, although it can improve the cutting effect of the exhaust pipe, during the laser cutting process, it is necessary to hold the handheld laser cutting machine, which may generate sparks and metal splashes. If these splashes splash into the eyes or glasses, they may not only scratch the eyes, but also burn the skin or eyes due to high temperature. Therefore, a laser cutting structure for automobile exhaust pipes is proposed to solve the above problems. Summary of the Utility Model

[0005] In order to solve the above technical problems, the utility model proposes a laser cutting structure for automobile exhaust pipes. By setting an automatic circumferential cutting method, automatic cutting is realized, avoiding manual holding of the handheld laser cutting machine for cutting, and improving the stability during the cutting process.

[0006] The technical solution for achieving the purpose of the present utility model is as follows: An automotive exhaust pipe laser cutting structure includes a base. The upper surface of the base is fixedly connected with a bottom plate. The upper surface of the bottom plate is provided with a disc. A circular groove is opened on one side of the disc. The inner wall of the circular groove is slidably connected with a plurality of arc-shaped blocks. One side of the plurality of arc-shaped blocks is fixedly connected with the same toothed ring. One side of the toothed ring is fixedly connected with a fixing plate. A laser cutting gun is arranged on one side of the fixing plate. A first motor is fixedly installed on the side of the disc away from the toothed ring. A gear is rotatably connected to the side of the disc away from the first motor. One side of the gear is fixedly connected with the output end of the first motor through a rotating shaft. The gear meshes with the toothed ring.

[0007] In some embodiments, a dovetail groove is opened on one side of the fixing plate. The inner wall of the dovetail groove is slidably connected with a dovetail block. One side of the dovetail block is fixedly connected with a mounting ring. The inner wall of the mounting ring is fixedly connected with the surface of the laser cutting gun.

[0008] In some embodiments, a first threaded rod is rotatably connected to the inner wall of the dovetail groove. A threaded hole is opened on one side of the dovetail block. The inner wall of the threaded hole is threadedly connected with the surface of the first threaded rod. One end of the first threaded rod is fixedly connected with a handle.

[0009] In some embodiments, a fixed seat is fixedly connected to the upper surface of the bottom plate. The top end of the fixed seat is fixedly connected with a fixed rod. The top end of the fixed rod is fixedly connected with a supporting ring. Two fastening bolts are threadedly connected to the surface of the supporting ring. One end of each of the two fastening bolts is fixedly connected with a clamping ring.

[0010] In some embodiments, a chute is opened on the upper surface of the bottom plate. A second threaded rod is rotatably connected to the inner wall of the chute. A sliding seat is slidably connected to the inner wall of the chute. A threaded hole is opened on one side of the sliding seat. The inner wall of the threaded hole is threadedly connected with the surface of the second threaded rod. The upper surface of the sliding seat is fixedly connected with the surface of the disc.

[0011] In some embodiments, a second motor is fixedly installed on one side of the bottom plate. The output end of the second motor is fixedly connected with one end of the second threaded rod.

[0012] Compared with the prior art, the present utility model has the following remarkable advantages:

[0013] Firstly: By starting the first motor, the rotation of the gear is driven by the first motor. Through the rotation of the gear, the rotation of the toothed ring can be driven. Through the rotation of the toothed ring, the fixing plate fixed thereon can be driven to rotate accordingly. Thus, while improving the cutting stability and accuracy, automatic cutting can be realized, avoiding the harm to the body caused by the sparks and flying objects generated during cutting.

[0014] Second: By adjusting the fastening bolts provided on the two support rings of the present utility model, the position of the clamping plate can be adjusted, thereby fixing exhaust pipes of different specifications. Then, by rotating the handle, the first threaded rod can be driven to rotate. Through the rotation of the first threaded rod, the dovetail block can be rotated inside the dovetail groove, thereby driving the laser cutting gun to adjust to a suitable cutting position.

[0015] This solves the problem that during the laser cutting process, it is necessary to hold the laser cutting machine by hand, which may generate sparks and metal splashes. If these splashes hit the eyes or glasses, they may not only scratch the eyes but also burn the skin or eyes due to high temperature. Brief Description of the Drawings
