[0002] The exhaust pipe is one of the important components in a car. Due to its special shape and installation position restrictions, the exhaust pipe needs to be connected together by welding. After welding the exhaust pipe, welding slag and burrs will appear. The welding slag needs to be cleaned by grinding to make its surface smoother and more beautiful.

[0003] The following technical problems exist in the assembly and welding of current automobile exhaust pipes:

[0004] 1. The exhaust pipe welding operation and post-welding grinding operation need to be carried out in two stations. First, the two sections of exhaust pipe are stably connected in the welding station. After forming, they are transferred to the grinding station to grind away the welding slag. The exhaust pipe needs to be clamped and fixed in both the welding station and the grinding station. The exhaust pipe needs to be clamped and fixed twice, resulting in low overall operation efficiency.

[0005] 2. The smoke and dust generated during welding and grinding are difficult to centrally handle, affecting the on-site environment.

[0006] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content

[0007] In response to the deficiencies in the background technology, the utility model provides an integrated welding and polishing forming device for automobile exhaust pipes, which can enable the exhaust pipes to be welded and polished in sequence after being clamped and fixed, eliminating the need for repeated clamping of the exhaust pipes, thereby significantly improving overall operating efficiency; and can centrally process the smoke and dust generated during the welding and polishing processes.
