Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a multi-dimensional exhaust pipe inspection tool. Background Technology

[0002] The automotive exhaust system is a crucial assembly for emitting exhaust gases and reducing noise. It mainly consists of the exhaust pipe, catalytic converter, muffler, and tailpipe. Its primary function is to collect, clean (via a three-way catalytic converter), and silence the exhaust gases produced during engine combustion from multiple cylinders before leading them to the rear of the vehicle for emission. Due to limitations imposed by vehicle installation space, airflow resistance, thermal expansion, and manufacturing processes, automotive exhaust pipes typically feature multiple bending paths. After the bending process, relevant inspections are necessary to check the exhaust pipe's fit to the vehicle body and ensure there are no dimensional errors. Size issues after installation not only severely impact production schedules but also increase manufacturing costs. Therefore, providing a sophisticated, efficient, and easy-to-use multi-dimensional exhaust pipe inspection tool before shipment is a critical technical problem that needs to be addressed in this case.
