Description

Technical Field

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

[0002] The car muffler is a part used to reduce the noise generated by the engine of a motor vehicle. Since the difference in length between the two pipes is equal to half the wavelength of the sound waves emitted by the car, the two sound waves interfere and cancel each other out when superimposed, thereby reducing the sound intensity and reducing the sound, thereby achieving a silencing effect.

[0003] The structure of the muffler itself is relatively complex, and there are usually certain space limitations at the weld, which brings great difficulties to manual welding. Therefore, the use of welding fixtures is a common method that can effectively ensure that the position of the muffler is fixed and the posture is stable during the welding process, thereby improving the welding quality and efficiency. During the design and manufacturing process of existing welding fixtures, various factors such as temperature changes and vibrations during the use of the muffler may not be fully considered. This may cause the muffler body to shake and shift during the welding process, making it impossible to stably maintain it inside the fixture, thereby affecting the welding quality. In addition, the design of some welding fixtures may not achieve the best fit with the muffler. Therefore, in actual use, it may be found that the friction between the muffler and the fixture is insufficient, resulting in relative movement during the welding process, affecting the welding quality.
