The vehicle body repair measurement technique is a key element in repairing the accident vehicle and ensures that the body structure is restored to the original plant standards and that the vehicle is safe. Many of the drivers may not know much about this technology, but it is like a “psychological examination” of the body, judging the extent of the damage through precise data. Basic measurement tools
Common basic measurement tools include roll, horizontal and steel straight feet. A roller ruler is used to measure the length and width of all parts of the body, the horizontal instrument ensures that the body is in a horizontal state and the steel is used to detect the plane level. These tools are simple and are the basic equipment of maintenance technicians and allow for quick access to preliminary data。
Specialized measurement systems
With technological development, specialized measurement systems, such as laser meters and the 3d scanning system, are becoming more widespread. By launching laser beams, the laser gauge captures the three-dimensional coordinates of the body and the error can be controlled at the millimetre level. The 3d scan system produces a three-dimensional model of the body, showing intuitively the location and degree of deformation compared to the original plant data。
Measuring processes and standards
Body repair measurements are subject to a strict process: first, the vehicle is fixed to ensure consistency of measurement benchmarks; then the key control points, such as the body axle distance, cycling and diagonal length, are measured; and finally, the data are compared with the original plant manual to determine whether corrections are required. Industry standards typically require measuring errors of up to ± 2 mm to ensure repair quality。
Technology application scenario
This technology is widely applied to accident vehicle repair, especially in case of deformation of the frame. For example, in the event of a vehicle collision, measurements determine the amount of deformation of structural elements such as vertical beams, poles, etc., to provide the basis for subsequent correction. In addition, in second-hand vehicle testing, measurement techniques can help to identify hidden injuries and avoid the purchase of accident vehicles。
The mastery of body repair measurement techniques not only improves the efficiency of maintenance, but also ensures safety after repair. For the owner, knowledge of this technology facilitates the selection of formal maintenance facilities and ensures that vehicles are professionally repaired。
