Abstract

The invention provides equipment for detecting the NVH of an automobile steering device and a working method thereof. The equipment comprises a base, a support frame and a detection mechanism. The support frame is fixed above the base. A numerical control display screen is arranged on the right of the support frame. A pendant is arranged on the left of the support frame. The detection mechanism islocated in the supporting frame. A bottom plate is arranged in the supporting frame. The detection mechanism comprises a loading mechanism, a detection assembly, a driving mechanism and a bearing mechanism. The driving mechanism provides power for the bearing mechanism, a first sliding rail is arranged between the bearing mechanism and the bottom plate, and a second sliding rail is arranged between the loading mechanism and the bottom plate. The working method comprises the steps S1 to S5. When the detection equipment is used, detection personnel can check various NVH indexes of the to-be-detected steering gear through the numerical control display screen and can also judge whether the product has abnormal sound or not in a manual mode, so that the production quality of the steering gearis guaranteed, and the production efficiency is also improved.

Description

technical field [0001] The invention relates to the technical field of detection equipment, in particular to a device for detecting the NVH of an automobile steering gear and a working method thereof. Background technique [0002] The English abbreviation of Noise, Vibration, Harshness (Noise, Vibration, Harshness) is NVH, which is one of the important indicators to measure the quality of automobile manufacturing. The NVH problem of vehicles is one of the concerns of major vehicle manufacturers and parts companies in the international automobile industry. The steering gear is one of the important parts of automobile production, and it is particularly important to detect the NVH index of the steering gear for automobile production. At present, the NVH detection of the steering gear mainly relies on manual noise detection of the steering gear to determine whether the product has abnormal noise, which may lead to inaccurate detection results.
