Six-post type three-dimensional visual detection system for automobile wheel alignment parameters

Abstract

The invention discloses a six-post type three-dimensional visual detection system for automobile wheel alignment parameters, which aims to overcome the problem that the existing detection system adopts a high precision straight-line guide rail, is complex in structure, high in manufacturing cost and not suitable for wide range popularization, and cannot be adjusted to an asymmetric measurement system. The system comprises a front right plane mirror rapid clamping locating device (A), a front left plane mirror rapid clamping locating device (B), a rear right plane mirror rapid clamping locating device (C), a rear left plane mirror rapid clamping locating device (D), a left position adjustable camera mounting system (F) and a right position adjustable camera mounting system (E). The detection system disclosed by the invention can complete accurate measurement of the wheel alignment parameters during the detection process.

Description

technical field [0001] The invention relates to a detection device in the field of automobile industry, more specifically, it relates to a six-column vehicle wheel alignment parameter stereo vision detection system. Background technique [0002] In order to ensure the handling stability of the car, the installation between the wheels, steering knuckle and axle shaft of the car has a certain relative position, which is called wheel alignment. Whether the vehicle wheel parameters are accurate or not has an important impact on the driving safety, handling stability and fuel economy of the vehicle. The wheel aligner is an important testing device for checking the safety of the vehicle. At present, there are more than 30,000 wheel aligners in the country alone, and the number is increasing at an annual rate of 30%. [0003] Stereo vision measurement of wheel alignment parameters can achieve non-contact detection. The distance between the two cameras in the measurement system is...

Problems solved by technology

[0004] In view of the high-precision linear guide rail used in the current detection system, the manufacturing cost is high, it is not suitable for large-scale promotion, and it is impossible to realize the asymmetric adjustment of the relative position and angle between the components of the machine vision detection system to achieve high-precision non-contact detection of vehicle wheel positioning parameters. In the present situation, it provides a non-contact sensor with small size, adjustable position and angle of parts, low manufacturing cost, simple operation, reliable performance, strong versatility and easy installation, which can meet the needs of national metrology, quality supervision departments and manufacturers.
