Problems solved by technology

Therefore, when testing the three-way catalytic converter assembly, it is necessary to check whether the key components such as the position of the hook, the through hole of the inlet flange, the through hole of the outlet flange, the assembly size, and the position of the installation hole of the heat shield can reach the design accuracy. , To meet the assembly requirements, if the key components are tested one by one, it will inevitably take a lot of time, which will not only affect the production efficiency, but also difficult to guarantee the detection accuracy

Abstract

The invention discloses an inspection device for a three-way catalyst assembly of an automobile. The inspection device comprises a base, a benchmark positioning mechanism, a guide supporting mechanism, a support location detecting mechanism, an oxygen sensor base and hanging hook location detecting mechanism and a discharge flange detecting mechanism, wherein the benchmark positioning mechanism, the guide supporting mechanism, the support location detecting mechanism, the oxygen sensor base and hanging hook location detecting mechanism and the discharge flange detecting mechanism are respectively fixed on the base according to the mutual corresponding relations with the three-way catalyst assembly. The inspection device is easy and convenient to operate, high in detecting accuracy and capable of detecting whether a key assembly location satisfies the assembly requirements and tolerance design requirements, improving detecting tact and enhancing production efficiency.

Description

technical field [0001] The invention belongs to a checking tool for an automobile engine exhaust system, in particular to a checking tool for an automobile three-way catalytic converter assembly. Background technique [0002] With the development of science and technology and the continuous application of advanced processing technology, the precision of mechanical products is getting higher and higher, so the assembly requirements of parts are also getting higher and higher. For the three-way catalytic converter assembly, its vehicle assembly status not only affects the performance and emissions of the vehicle, but also subjectively affects the customer's recognition of the quality of the vehicle. Therefore, when testing the three-way catalytic converter assembly, it is necessary to check whether the key components such as the position of the hook, the through hole of the inlet flange, the through hole of the outlet flange, the assembly size, and the position of the installa...
