[0038] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] Referring to Figure 1 , Figure 3 and Figure 4 , an embodiment provided by the present invention: a laser cutting device for elbow pipe fittings, including a bottom table 1, the inner bottom wall of the bottom table 1 is fixedly connected with a steel plate 3, the top wall of the steel plate 3 is fixedly connected with a tooth seat table 4, the inner wall of the tooth seat table 4 is rotatably connected with a rotating table 5, the front inner wall of the rotating table 5 is fixedly connected with a servo motor 6, the output end of the servo motor 6 is fixedly connected with a driving gear 7, the driving gear 7 is meshed with the top wall of the tooth seat table 4, vertical plates 8 are fixedly connected to both the left and right sides of the tooth seat table 4, an electric push rod 9 is fixedly connected to the inside of the vertical plate 8, one end of the electric push rod 9 is fixedly connected with a mounting plate 10, bolts 11 are threadedly connected to both the upper and lower ends of one side of the mounting plate 10, a fixing clip 12 is threadedly connected to one end of the bolt 11, a vertical frame 15 is fixedly connected to the top wall of the bottom table 1, a cylinder 16 is fixedly connected to the front side of the vertical frame 15, a cutting device 17 is fixedly connected to the front side of the cylinder 16, and an extraction mechanism 2 is arranged at the rear side of the vertical frame 15;

[0040] Specifically, by selecting a suitable fixing clip 12, rotating the bolt 11 enables the fixing clip 12 to be disassembled from one side of the mounting plate 10, and by rotating the bolt 11 again, the selected fixing clip 12 is fixedly installed on one side of the mounting plate 10, thereby improving the applicable range of the device, enabling the device to handle pipe fittings of different specifications, achieving the purpose of clamping and fixing the pipe fittings. When the servo motor 6 is started, the driving gear 7 rotates on the top wall of the tooth seat table 4, thereby driving the rotating table 5 to rotate inside the tooth seat table 4. This enables the angle adjustment of the already fixed elbow pipe fittings. The cylinder 16 can drive the cutting device 17 to perform cutting work, ultimately improving the flexibility of cutting, increasing the diversity and accuracy of pipe fitting cutting, and making the entire cutting process more efficient and accurate.

[0041] Referring to Figure 1 , Figure 2 and Figure 5, the extraction mechanism 2 includes a connecting plate 201. The front side of the connecting plate 201 is fixedly connected to the rear side of the vertical frame 15. The right side of the top wall of the connecting plate 201 is fixedly connected with an extraction fan 202. The left end of the rear side of the extraction fan 202 is fixedly connected with an extraction pipe 203. One end of the extraction pipe 203 communicates with a filter box 204. A filter plate 205 is slidably installed in the middle of the inner wall of the filter box 204. A filter carbon plate 207 is fixedly installed on the front side of the inner wall of the filter box 204. The rear end of the filter box 204 communicates with a connecting pipe 208. The front end of the connecting pipe 208 communicates with an extraction head 209. The top wall of the extraction head 209 is fixedly connected to the bottom wall of the connecting plate 201;

[0042] Specifically, by starting the extraction fan 202, it is possible to extract the flue gas generated during the cutting process. The extraction head 209 will suck in the flue gas generated during cutting, and then guide the flue gas into the interior of the filter box 204 through the connecting pipe 208. The flue gas will undergo double filtration treatment by the filter plate 205 and the filter carbon plate 207, which can effectively remove the harmful substances contained in the flue gas, ensuring that the filtered air flow can be discharged more cleanly into the external air through the extraction fan 202, reducing the pollution of the waste smoke generated during cutting to the surrounding air environment. The air flow extracted by the extraction fan 202 can cool the surface of the pipe fitting, improve the fluidity of the air flow on its surface, and thus improve the cooling efficiency of the pipe fitting after processing, making the entire cutting and cooling process more efficient and environmentally friendly.

[0043] Refer to Figure 1 , Figure 2 and Figure 5 , the extraction mechanism 2 further includes a handle 206. The bottom wall of the handle 206 is fixedly connected to the top wall of the filter plate 205. A rubber sleeve 211 is fixedly connected to the middle of the handle 206; The right side of the vertical frame 15 is fixedly connected with a control switch 18. The control switch 18 is electrically connected to the servo motor 6, the electric push rod 9, the cylinder 16, the cutting device 17, and the extraction fan 202 respectively; A rubber ring 210 is fixedly installed at the bottom end of the outer wall of the connecting pipe 208. The outer wall of the rubber ring 210 is fixedly connected to the rear side of the extraction head 209;

[0044] Specifically, the handle 206 and the rubber sleeve 211 make it convenient to lift the filter plate 205 for replacement. Through the control switch 18 respectively connected to the servo motor 6, the electric push rod 9, the cylinder 16, the cutting device 17, and the extraction fan 202, the control switch 18 can turn on and off the device. The rubber ring 210 improves the protection effect of the connection at the bottom end of the connecting pipe 208.

[0045] Refer to Figure 1 , Figure 2 andFigure 4 , a backing plate 14 is fixedly connected to the top wall of the rotating table 5, and a plurality of inclined surfaces are provided on the outer wall of the backing plate 14; a plurality of rubber strips 13 are fixedly connected to the adjacent sides of the two fixing clips 12, and the plurality of rubber strips 13 are arranged in an equidistant arc; two connecting seats 19 are fixedly connected to the left and right sides of the bottom table 1, and mounting grooves 20 are formed in the top walls of the plurality of connecting seats 19;

[0046] Specifically, the backing plate 14 can block the cutting laser, thereby avoiding damage to the tooth seat table 4 at the bottom. The static friction of the fixing clip 12 is increased through the rubber strips 13, thereby improving the fixing effect. The device can be conveniently fixedly installed through the connecting seats 19 and the mounting grooves 20.

[0047] Working principle: When starting to use, by selecting a suitable fixing clip 12, the rotating bolt 11 is rotated, so that the fixing clip 12 can be disassembled from one side of the mounting plate 10, and then the selected fixing clip 12 is fixedly installed through the bolt 11, thereby improving the applicable range of the equipment and facilitating the clamping and fixing of pipe fittings of different specifications. Then, by starting the servo motor 6, since the driving gear 7 is meshed with the tooth seat table 4, the driving gear 7 can rotate on the top wall of the tooth seat bar 4, driving the rotating table 5 to rotate inside the tooth seat table 4, and then the elbow pipe fitting fixed by the fixing clip 12 driven by the electric push rod 9 can be adjusted in angle. Then, the cutting equipment 17 is driven by the cylinder 16 to perform cutting work, thereby improving the flexibility of cutting, increasing the diverse requirements for pipe fitting cutting. And by starting the extraction fan 202, the extraction head 209 extracts the fumes generated during cutting, and the fumes enter the interior of the filter box 204 through the connecting pipe 208. Under the filtration of the filter plate 205 and the filter carbon plate 207, the harmful substances contained in the fumes can be filtered. Thus, the filtered air flow is discharged into the air through the extraction fan 202, reducing the pollution of the waste fumes generated by cutting to the air. At the same time, the extraction head 209 extracts the air flow to cool the cut pipe fittings, improving the fluidity of the air flow on the surface of the pipe fittings, and thus improving the cooling efficiency after pipe fitting processing.

[0048] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
