Description

Technical Field

[0001] The utility model relates to a welding technology for a connecting plate of an extended-range engine muffler, and particularly to a welding tooling for a connecting plate of an extended-range engine muffler. Background Art

[0002] The main body of the extended-range engine muffler is of a cylindrical structure. Therefore, it is also often referred to as a muffler cylinder. Moreover, annular protrusions are provided at both ends of the muffler cylinder, and a connecting plate is welded to each of the two ends of the muffler cylinder. According to the design requirements, the shapes and structures of the connecting plates welded to the two ends of the muffler cylinder are different. The connecting plate welded to the left end is L-shaped. One end of the left L-shaped connecting plate is welded to the left end of the muffler cylinder, and the other end is provided with two through holes, and the axes of the through holes are perpendicular to the axis of the cylinder. The right connecting plate welded to the right end is double-fold L-shaped. One end is welded to the right end of the muffler cylinder, and the other end is provided with two through holes, and the axes of the through holes are parallel to the axis of the cylinder (see attached Figure 1 、 2 , in the figure, a is the muffler cylinder, b is the left connecting plate, and c is the right connecting plate). During welding, in addition to requiring the left and right connecting plates to be welded to the set positions at the ends of the cylinder, it is also required that the through holes of the left and right connecting plates are in the set positions and the axes are perpendicular or parallel to the axis of the cylinder. The existing welding method for the connecting plates of the extended-range engine muffler uses a simple fixture to fix the welding end of the left connecting plate to the left end of the cylinder for welding, and then uses a simple fixture to fix the right connecting plate to the right end of the cylinder for welding; this method of using two clamps for fixed welding not only has a large labor intensity and low efficiency, but also it is very difficult to ensure that the through holes of the left and right connecting plates are in the set positions and the axes are perpendicular or parallel to the axis of the cylinder.
