[0047] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0048] Embodiment 1

[0049] Refer to Figures 1-5, A rapid welding device for sheet metal part processing, including a main body component 1, and the main body component 1 includes: a bottom plate 11, on the top of which there is a side plate 12; a welding mechanism 13, arranged on the side plate 12; a processing component 2 is arranged on the bottom plate 11 and the side plate 12, and the processing component 2 includes: supports 21, symmetrically arranged on the top of the bottom plate 11; a right-turn rod 22, rotatably connected to the right support 21, and the right-turn rod 22 penetrates through the right support 21; a left-turn rod 23, rotatably connected to the left support 21, and the left-turn rod 23 penetrates through the left support 21; a first motor 221, the output shaft of which is fixedly connected to the right end of the right-turn rod 22; a connecting rod 24, arranged on the left side wall of the right-turn rod 22; a connecting hole 241, opened on the right side wall of the left-turn rod 23; electric push rods 25, symmetrically arranged on the opposite surfaces of the supports 21; push plates 251, respectively rotatably connected to the right-turn rod 22 and the left-turn rod 23, and the push plates 251 are fixedly connected to the output shafts of the two electric push rods 25; fixing mechanisms 26, symmetrically arranged on the right-turn rod 22 and the left-turn rod 23. The fixing mechanism 26 includes: a second motor 261, arranged in the internal cavity of the right-turn rod 22 and the left-turn rod 23; a bevel gear 262, fixedly connected to the output shaft of the second motor 261; threaded sleeves 263, symmetrically and circumferentially penetrating through the right-turn rod 22 and the left-turn rod 23; lead screws 264, threadedly connected to the inside of the threaded sleeves 263; bevel gears 265, arranged at the opposite ends of the lead screws 264, and the bevel gears 265 are meshed with the bevel gear 262; fixing blocks 266, arranged at one end of the threaded sleeves 263 outside the right-turn rod 22 and the left-turn rod 23. Limit plates 252 are arranged at the opposite ends of the right-turn rod 22 and the left-turn rod 23.

[0050] In use, the driving electric push rod 25 contracts, and the electric push rod 25 drives the push plate 251 to separate the left turning rod 23 and the right turning rod 22 from each other. At this time, the two tubular sheet metals to be welded are sleeved outside the left turning rod 23 and the right turning rod 22, and the edges of the tubular sheet metals are aligned with the edges of the left turning rod 23 and the right turning rod 22 respectively. The two tubular sheet metals are fixed by the fixing mechanism 26: start the second motor 261, the second motor 261 drives the bevel gear 262 to rotate, the bevel gear 262 drives a plurality of meshed bevel gears 265 around it to rotate synchronously. When the bevel gear 265 drives the lead screw 264 to rotate, the threaded sleeve 263 threadedly connected to the outside of the lead screw 264 drives the fixing block 266 to extend outward until the fixing block 266 abuts against the inner wall of the tubular sheet metal. Turn off the second motor 261. At this time, a plurality of fixing blocks 266 support the inner wall of the tubular sheet metal to fix the parts, avoiding the movement or inward depression of the parts during welding, which affects the welding quality. After the sheet metal parts are fixed, start the two electric push rods 25. The electric push rods 25 push the push plate 251, so that the left turning rod 23 abuts against the right turning rod 22, and the connecting rod 24 on the right turning rod 22 extends into the connecting hole 241 on the left turning rod 23, facilitating the right turning rod 22 to drive the left turning rod 23. Start the first motor 221, and the first motor 221 drives the right turning rod 22 and the left turning rod 23 to rotate. The fixed tubular sheet metal parts rotate, facilitating the welding mechanism 13 above to weld the contact parts of the parts, improving the welding efficiency. The welding mechanism 13 mentioned above adopts a conventional welding method. For example, a welding gun that can realize the welding of metals by using the chemical reaction heat and arc radiation heat generated by hydrogen can be used, as long as the welding of the sheet metal parts can be realized. The specific structure will not be elaborated here. The limiting plate 252 limits the sliding of the left turning rod 23 and the right turning rod 22 on the support 21. The electric push rod 25 pushes the push plate 251 to move. When the limiting plate 252 contacts the outer wall of the support 21, turn off the electric push rod 25. At this time, the left turning rod 23 abuts against the right turning rod 22, and the contact position is directly below the welding mechanism 13, improving the welding accuracy of the welding mechanism 13.

[0051] Embodiment 2

[0052] On the basis of Embodiment 1, an auxiliary function is added.

[0053] Refer to Figures 1-5 As shown in [reference figure], an auxiliary mechanism 27 is provided on the side plate 12. The auxiliary mechanism 27 includes: a chute 271 opened on the front side wall of the side plate 12; a slider 272 slidably connected to the chute 271, and a through groove is opened on the slider 272; an auxiliary plate 273 slidably connected to the through groove on the slider 272. An anti-slip pad 3 is provided on the outside of the fixing block 266. A plate body 267 is provided on the outer side wall of one end of the threaded sleeve 263 located inside the right turning rod 22 and the left turning rod 23.

[0054] The auxiliary mechanism 27 facilitates the alignment of the edges of the tubular sheet metal part with the edges of the left turning rod 23 and the right turning rod 22 by the staff. When alignment is required, the staff moves the slider 272, and the slider 272 drives the auxiliary plate 273 to slide on the chute 271. The auxiliary plate 273 moves to abut against the right side of the left turning rod 23. The tubular sheet metal part is moved so that the outer side of the sheet metal part contacts the auxiliary plate 273. At this time, the tubular sheet metal part is fixed by the fixing mechanism 26 inside the left turning rod 23. Then the slider 272 is moved, and the auxiliary plate 273 aligns the sheet metal part at the right turning rod 22. After the alignment and fixation of the two sheet metal parts are completed, the auxiliary plate 273 is pulled out upward, and the auxiliary plate 273 is taken out from the slider 272 to avoid affecting the welding of the welding mechanism 13. The anti-slip pad 3 increases the friction between the fixing block 266 and the inner wall of the tubular sheet metal part, enhances the fixing effect of the fixing block 266, and prevents the sheet metal part from moving. The plate body 267 controls the length of the threaded sleeve 263 extending out to prevent the entire threaded sleeve 263 from moving out of the left turning rod 23 and the right turning rod 22.

[0055] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
