Abstract

The invention relates to an automobile chassis rear-overhang part assembly simulated detection tool and detection analysis method. According to the detection tool, the tool is assembled on a detectionplatform and detection equipment is used to measure the tolerance of the tool after assembly, the tool is used to detect parameters including function, size and manufacturing deviation of automobilechassis rear-overhang parts and function and size of a general assembly, whether a chassis rear-overhang unit is qualified is detected, a deviation accumulated phenomenon in the chassis rear-overhangassembling process is simulated, influence of a manufacturing deviation accumulation effect of parts in the assembling process on the function and size of the assembled general rear-overhang assemblyis analyzed and compared to obtain contribution of the manufacturing deviation of each part to the final assembling error, and thus, guidance is provided for tolerance optimization of the parts, the rear-overhang assembling precision is improved, and the driving performance of the whole automobile is improved.

Description

technical field [0001] The invention relates to the field of assembly of automobile chassis parts, in particular to a simulated detection tool and a detection and analysis method for the accumulation of parts deviation in the process of a rear suspension device of an automobile chassis. Background technique [0002] At present, domestic automobile manufacturers mostly control the dimensional accuracy of the chassis from the manufacturing accuracy of parts. Taking the rear suspension system of the chassis as an example, it is composed of rear suspension shock absorbers, shock absorbing spring bases, torsion beams, longitudinal swing arms and other parts. , when controlling the dimensional accuracy, the automobile manufacturer puts forward design requirements for the manufacturing tolerance of these parts, that is, the manufacturing deviation of the parts needs to be controlled within a certain range before the assembly of the rear suspension can be carried out. Sometimes consi...
