The assembly frame 1 includes a frame body 11 and a turntable mounting seat 12 for assembling a turntable 21, and a toothed belt 31 is arranged on the driving motor 3.

[0031] like Figure 4-5 As shown, the turntable mounting seat 12 includes a semicircular fixed seat 121 fixed on the frame 11 by bolts, and a semicircular clamping seat 122 fixed to the semicircular fixed seat 121 by bolts for fixing the turntable 21. The semicircular fixed seat 121 is provided with a fixed seat U-shaped groove 1211, and the fixed seat pulley 1212 assembled by a fixed shaft is equidistantly installed on the fixed seat U-shaped groove 1211; the semicircular clamping seat 122 is provided with a clamping seat U-shaped groove 1221, and the clamping seat pulley 1222 assembled by a fixed shaft is equidistantly installed on the clamping seat U-shaped groove 1221; specifically, when the semicircular clamping seat 122 cooperates with the semicircular fixed seat 121 to assemble the turntable 21, the metal cylinder 212 contacts the fixed seat pulley 1212 and the clamping seat pulley 1222, so that the turntable 21 can rotate on the turntable mounting seat 12, thereby realizing the air duct rotation cutting process during the laser cutting process.

[0032] like Figure 6 As shown, the clamp assembly 2 includes a turntable 21 with a hollow middle, a slide 22 fixedly mounted on the surface of the turntable by screws and distributed equidistantly in a ring, an air duct extrusion seat 23 movably assembled on the slide 22, and a cylinder 24 fixedly mounted on the front end of the slide 22 by an angle steel and capable of driving the air duct extrusion seat 23 to move on the slide 22 to clamp the air duct.

[0033] Specifically, the slide seats that are evenly distributed in an annular shape and fixed by screws and the air duct extrusion seat that is fixed by angle steel make the entire fixture assembly structure firm and able to withstand the extrusion and movement force during the cutting process. The air duct extrusion seat is movably assembled on the slide seat by the cylinder, and can be adjusted according to air ducts of different sizes and shapes. It has strong applicability and flexibility. The slide seats on the surface of the turntable are evenly distributed in an annular shape, which can provide uniform support force, ensure the stability of the air duct during the cutting process, and improve the cutting accuracy and quality. In addition, the cylinder drives the air duct extrusion seat to move on the slide seat, which is simple and convenient to operate, and can quickly clamp and release the air duct, thereby improving production efficiency.

[0036] It should be further explained that a Y-shaped assembly frame fixing groove 2311 is provided at the upper end of the slider 231, and an auxiliary pressure block embedding groove 2312 is provided at the front end of the slider 231. Specifically, the Y-shaped assembly frame fixing groove 2311 and the auxiliary pressure block embedding groove 2312 can enable the Y-shaped assembly frame 232 and the auxiliary pressure block 234 to be stably installed.

[0037] It should be further explained that a baffle 2321 is fixed by bolts to the portion of the Y-shaped assembly frame 232 corresponding to the assembly of the air duct contact roller 233 , which can specifically block sparks generated during the air duct laser cutting process, thereby protecting the air duct contact roller 233 .

[0038] It should be further explained that a pressure wheel assembly groove 2341 is integrally formed at the front end of the auxiliary pressure block 234 .

[0039] See attached Figure 2-3 and attached Figure 7 By meshing the toothed belt 31 with the gear ring 213 , the turntable 21 can be controlled by the driving motor 3 to rotate on the turntable mounting seat 12 .

[0040] The above-mentioned embodiments of the utility model are not intended to limit the protection scope of the utility model, and the implementation methods of the utility model are not limited to these. All other various forms of modifications, replacements or changes made to the above-mentioned structure of the utility model based on the above-mentioned contents of the utility model, in accordance with the common technical knowledge and customary means in the field, without departing from the above-mentioned basic technical ideas of the utility model, should fall within the protection scope of the utility model.
