The invention relates to a vehicle body shape deviation detection device, which includes a vehicle rear axle alignment device respectively arranged on the ground, one side and above the detection site, a front camera set on a frame lifting mechanism through a camera turntable, The vehicle body height difference measurement device composed of the rear camera and the height displacement sensor that feedbacks the vertical displacement of the camera, the roof camera that is set on the slide table that can move longitudinally along the suspended guide rail through the camera turntable, and the vertical or horizontal feedback cameras respectively A shaft deflection angle measuring device composed of a longitudinal displacement sensor and a lateral displacement sensor and a computer control system. When the car is driven into the testing site, it can quickly and non-contact detect the height difference between the left and right symmetrical points of the outer edge of the car body and the deflection angle between the car body and the rear axle, providing effective car testing equipment for the detection of car body shape deviation. Greatly improve its work efficiency and detection accuracy.
Description
technical field [0001] The invention belongs to automobile performance testing equipment, in particular to a non-contact vehicle testing equipment for testing the shape and position deviation of the whole vehicle. Background technique [0002] Vehicle body shape deviation refers to the height difference between the left and right symmetrical points of the vehicle body (that is, the deflection angle of the vehicle body or relative to the horizontal plane), and the deflection angle of the centerline of the rear axle of the vehicle relative to the longitudinal axis of the vehicle body, which is caused by the above two deviations Body shape changes and position changes. [0003] During the use of the car, the longitudinal axis of the car body is not perpendicular to the rear axle due to the deformation of the frame, the deformation and movement of the axle, the loosening of the saddle bolts, the wear and looseness of the axle joints and other reasons. When the car is running st...
