Problems solved by technology
[0004] The present invention mainly provides a double-reference automotive longitudinal beam inspection tool with simple structure and high detection efficiency, which can not only detect the forming size of the longitudinal beam stamping parts, but also detect the matching size of the longitudinal beam welding process. It eliminates the need to make corresponding inspection tools for the stamping parts of the longitudinal beam and the matching size inspection of the welding process in the prior art, and the switching time of the inspection tools is long during the inspection, which leads to high production costs and labor costs, and low inspection efficiency other technical issues

The invention discloses an automobile girder inspection device and provides a double-reference automobile girder inspection device, which has the advantages of simple structure and high detection efficiency and is not only capable of detecting the formed size of a girder stamping part but also capable of detecting the matching size in a girder welding process. The technical problems, such as high manufacture cost and labour cost and low detection efficiency, caused by long switch time of inspection devices in the process of detection because corresponding inspection devices need to be respectively manufactured while the stamping part of a girder and the matching size in the welding process are detected in the prior art can be solved. The double-reference automobile girder inspection device comprises an inspection device body corresponding to an installation surface and locating holes on the girder, wherein the inspection device body comprises a basal body, a plurality of reference zero-potential surfaces and bolts; the plurality of reference zero-potential surfaces and the bolts are movably connected onto the basal body; the reference zero-potential surfaces respectively correspond to various process detection reference surfaces on the girder; and the bolts are in inserted connection with the interior of the locating holes correspondingly.
Description
technical field [0001] The invention relates to an automobile longitudinal beam inspection tool, in particular to a double-reference automobile longitudinal beam inspection tool which can detect both the forming size of the longitudinal beam stamping parts and the matching size of the longitudinal beam welding process. Background technique [0002] RPS is a reference point system throughout the automobile design and manufacturing process, which is used to ensure the dimensional stability and function of auto parts. Therefore, RPS is a positioning system commonly used in the current automobile manufacturing process. In order to ensure the unity of RPS, the positioning holes on the existing longitudinal beam inspection tool are used for the forming size inspection of stamping parts and the matching size inspection of welding process, that is, the two inspections use the same benchmark, so that the inspection tool is qualified. The longitudinal beam components are often unable ...
