Rear silencer assembly welding fixture of automobile exhaust system

Abstract

The invention discloses a rear silencer assembly welding fixture of an automobile exhaust system. The welding fixture comprises a flange positioning device, a gas inlet pipe positioning device, a silencer positioning device, an exhaust pipe positioning device, a first hook positioning device and a second hook positioning device that are used for accurately positioning and effectively fixing a flange, a gas inlet pipe, a silencer, an exhaust pipe, a first rear silencer hook and a second rear silencer hook respectively, wherein the flange positioning device, the gas inlet pipe positioning device, the silencer positioning device, the exhaust pipe positioning device, the first hook positioning device and the second hook positioning device correspond to positions of the flange, the gas inlet pipe, the silencer, the exhaust pipe, the first rear silencer hook and the second rear silencer hook respectively and are arranged above a mounting substrate with the smooth upper surface; the fixture is used for welding assembly of a silencer assembly; spare parts are precise in positioning and convenient to mount and fetch; and the fixture guarantees production efficiency and can meet large-scaleproduction requirements.

Description

technical field [0001] The invention relates to a component welding tool for an automobile exhaust system, in particular to a welding fixture for a rear exhaust assembly of an automobile exhaust system. Background technique [0002] With the improvement of people's living standards, owning a car is becoming more and more common for ordinary families, which makes the automobile industry increasingly vigorous, with a large demand for output and high requirements for production quality and production efficiency. [0003] For the welding and assembly of the catalyst part or the muffler part of the automobile exhaust pipe system, it is necessary to position and splice a large number of special-shaped parts and then load them for welding; the welding positioning accuracy and quality of auto parts have high requirements, so manual hand-held positioning Welding is never acceptable and results in substandard precision, inefficiencies and unusable finished products. [0004] Therefor...
