Description

Technical Field

[0001] The utility model relates to the field of muffler production, and more specifically, to an automobile muffler assembly workbench. Background Art

[0002] Cars are very common in people's lives. The emergence of cars has greatly facilitated people's lives and travel. Cars will generate loud noise during the exhaust process, so it is necessary to install a car muffler on the exhaust pipe to reduce the noise generated during the exhaust process of the car. In the production process of the car muffler, it is often necessary to assemble it through different parts, so it is necessary to use an assembly workbench to assemble the muffler. The muffler is generally assembled from multiple pipe fittings. When assembling the muffler, the existing assembly workbench can generally only fix and assemble two pipe fittings at the same time. After the two pipe fittings are assembled, new pipe fittings need to be fixed and assembled again, which wastes a lot of assembly time and is inconvenient to assemble the muffler. At the same time, the existing assembly workbench generally cannot be adjusted in multiple directions, and the positions of different pipe fittings cannot be adjusted according to needs, which is inconvenient for the precise connection between different pipe fittings, thereby affecting the production quality of the muffler.
