The side wall tail light mounting hole detection device provided by the invention realizes positioning and size detecting for a side wall tail light mounting hole in a car body metal plate, and realizes real-time detection for side wall tail light mounting holes of each car beside a production line at the same time.

Description

Technical field [0001] The invention relates to the field of detection of automobile parts, in particular to a detection device for a side wall tail lamp mounting hole. Background technique [0002] During the assembly process of automobiles, the position accuracy of the side wall taillights on the white body is required to be very high. It is necessary to ensure that there is a precise three-dimensional space distance between the side wall taillights and the side wall, rear wall, and tailgate. If the side wall taillights are installed with out-of-to-size assembly problems, it will directly affect the assembly efficiency of the vehicle. [0003] In the prior art, due to the instability of the tooling and fixtures, the mounting holes of the side taillights on the body-in-white are prone to deviations during welding, so that the mounting holes of the side taillights do not meet the design requirements, resulting in the assembly of the side taillights. Dislocation occurs, causing the...

If there are problems such as out-of-tolerance assembly dimensions during installation of the side taillights, it will directly affect the assembly efficiency of the vehicle

[0003] In the prior art, due to the instability of the fixture, the mounting holes of the side tail lights on the body-in-white are prone to deviation during welding, so that the mounting holes of the side tail lights do not meet the design requirements, resulting in Dislocation occurs, causing the gap and surface difference between the side panel taillights and the side panel, rear panel, and tailgate to fail to meet the requirements, which may easily lead to rework or even scrap the parts

In the prior art, the installation holes of the side taillights are mainly detected by three coordinates. However, due to the inconsistent size deviation of each hole position, even if the coordinate value of a single hole position meets the requirements through the three coordinates detection, the two holes However, the distance between positions may be out of tolerance; in addition, the three-coordinate detection process is more complicated, and the detection efficiency is low, which is only suitable for sampling detection, and cannot ensure the dimensional accuracy of the mounting holes of the taillights on the upper side of each vehicle
