Three-dimensional inspection of automobile tailgate

The automotive industry has been developing for over a hundred years. Automobile is not only a popular means of transportation, but also an industrialized product with dynamic styling characteristics. In recent years, under the guidance of aesthetic principles and ergonomics, the design of car bodies, interior and exterior decorations, and spare parts has become increasingly changing.

Practical problem

It is necessary to quickly obtain a three-dimensional digital model of the vehicle tailgate and detect assembly errors of the vehicle tailgate. However, there are many holes in car doors, which have large deformation, and the shapes of grooves on each side are different, which is very complex. It is difficult to determine the uneven assembly clearance of plastic parts, and the height deviation of the mating surface of plastic parts.

Solutions

Hualang 3D engineers use a handheld 3D scanner HOLON B71 to scan the car tailgate from different angles and positions, accurately obtaining 3D data of the car tailgate, and performing comparative testing on the 3D data to obtain a very intuitive 3D detection chromatogram. According to the comparison report, the overall error of the actual production tailgate can be clearly seen, and the quality of the workpiece can be clearly known, such as where there are protrusions or recesses.
