Description

Technical Field

[0001] The utility model relates to the technical field of muffler processing, in particular to a welding tool for processing a muffler. Background Art

[0002] A silencer is a device that allows air to pass through while effectively preventing or reducing the propagation of sound energy. The outermost structure of the silencer is a cylindrical silencer, the interior of which is divided into multiple expansion chambers. Each adjacent expansion chamber is connected by a pipe, and a sudden change in cross section is formed between the pipe and the expansion chamber, so that the sound waves are reflected and interfered at the sudden change in cross section, thereby achieving the purpose of silencing. When processing the silencer, the flat plate is first rolled into a tube, and then the joints of the silencer are welded. In addition, in order to facilitate the installation of the silencer, it is necessary to weld a mounting bracket on the outer wall of the silencer.

[0003] According to the Chinese patent announcement number CN 214978961 U, a welding tool for processing a muffler is disclosed, which includes a counterweight base, a lifting plate arranged on the counterweight base in a longitudinal manner and a clamping assembly rotatably arranged on the lifting plate, the clamping assembly includes a support plate, a fixed clamping plate, a movable clamping plate, an elastic member, a fixed pulley, a retractable wheel and a rope, the support plate is rotatably connected to the lifting plate, the fixed clamping plate is fixedly connected to the support plate, the movable clamping plate is slidably connected to the support plate and arranged opposite to the fixed clamping plate, the elastic member is telescopically arranged between the movable clamping plate and the fixed clamping plate, the fixed pulley and the retractable wheel can be rotatably installed on the support plate, one end of the rope is connected to the movable clamping plate, the other end of the rope passes through the fixed clamping plate and bypasses the fixed pulley and then is wound on the retractable wheel, and two opposing pressure plates are arranged on the fixed clamping plate and the movable clamping plate. The welding tool of the utility model can adapt to the clamping of mufflers of different sizes and specifications, has a wide applicability, and is convenient for welding operations.

[0004] However, the welding tool is not stable enough when clamping and fixing the silencer. The position of the silencer may shift during the welding process, affecting the welding effect. At the same time, the welding tool may be affected by external vibrations during the welding process, affecting the quality of the welding. For this reason, we propose a welding tool for processing silencers. Utility Model Content
