Manufacturing and welding aftertreatment process of automobile exhaust pipe assembly

Abstract

The invention provides a manufacturing and welding aftertreatment process of an automobile exhaust pipe assembly. An execution mechanism, a clamping mechanism and a translation mechanism are included.The execution mechanism is arranged on the translation mechanism in a spiral fit manner. The clamping mechanism is mounted on the translation mechanism. According to the process, the problems that due to the limitations of special shapes and mounting positions of exhaust pipes, the exhaust pipes need to be connected together in a welded manner, welding slag and burrs will be generated after the exhaust pipes are welded, if the surfaces need to be smoother and more attractive, welding slag needs to be treated thoroughly through grinding, in traditional welding slag grinding, the exhaust pipesof a manufacturing assembly need to be located and fixed manually, then a grinding machine is used for grinding treatment, the manner is complex in process and large in worker labor intensity, no direction correction treatment is carried out on the clamped exhaust pipes, consequently, in later, exhaust pipe grinding is not attractive and not fine, and the grinding quality of exhaust pipes is hardto guarantee are solved.

Description

technical field [0001] The invention relates to the technical field of exhaust pipe processing, in particular to a post-welding process for manufacturing an automobile exhaust pipe assembly. Background technique [0002] Automobile exhaust bellows, also known as automobile exhaust pipe hose, is installed in the exhaust pipe between the engine exhaust branch pipe and the muffler, so that the entire exhaust system is flexibly connected, thereby reducing vibration and noise, and is convenient. The function of installing and prolonging the life of the exhaust muffler system; [0003] The exhaust pipe is one of the important parts in the car. Due to the special shape and installation position of the exhaust pipe, it needs to be connected together by welding. After the exhaust pipe is welded, there will be welding slag burrs, which need to be processed by grinding Clean to make the surface smoother and more beautiful. In traditional welding slag grinding, it is necessary to manua...

AI Technical Summary

Problems solved by technology

[0003] The exhaust pipe is one of the important parts in the car. Due to the special shape and installation position of the exhaust pipe, it needs to be connected together by welding. After the exhaust pipe is welded, there will be welding slag burrs, which need to be processed by grinding Clean to make the surface smoother and more beautiful. In traditional welding slag grinding, it is necessary to manually position and fix the exhaust pipe of the manufacturing assembly, and then use a grinding machine for grinding. This method is complicated and labor-intensive. In addition, the orientation of the clamped exhaust pipe is not corrected, so that the subsequent exhaust pipe is polished unsightly and not fine, and it is difficult to ensure the grinding quality of the exhaust pipe;
