This detection method needs to coordinate a lot of resources and time to realize the detection, which is not only troublesome to operate, but also takes a long time, which is not conducive to the rapid analysis of defects
The front face detection sample rack is used to detect the geometric size defects of the entire front face, and can detect the matching relationship between two or more sub-assemblies, but it needs to be tested after the entire vehicle is assembled, so it cannot detect a single sub-assembly. Assembly functional thickness

Embodiment Construction
[0018] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0019] Such as figure 1 As shown, the present invention includes a base 1, a detection block 2 and a positioning pin 3, the base 1 is Z-shaped, the level of one end is higher than the level of the other end, and the detection block 2 is fixed on the upper end surface of the higher end of the base 1, The positioning pin 3 is fixed on the upper end surface of the lower end of the base 1 . The upper end surface of the detection block 2 is a function detection surface 5, and the side facing the positioning pin 3 is fixed with a Y-direction stopper 4, and the end surface of the Y-direction stopper 4 for contact with the hood positioning surface 13 is the Y-direction positioning surface 6 . A positioning reference block 7 is fixed circumferentially in the middle part of the positioning pin 3. The positioning reference block 7 is annular, and its ann...

The invention relates to the technical field of geometric dimension detection of body-in-white, in particular to a tool for rapid detection of the thickness of the functional surface of a hood and a detection method thereof, including a base, a detection block and a positioning pin, and the detection block and the positioning pin are respectively fixed on two parts on the upper end surface of the base. The level of the end of the detection block installed on the upper end of the base is higher than that of the end of the positioning pin. The upper end of the detection block is a function detection surface, which is used to detect the thickness of the functional surface of the hood. The detection block is set on the side facing the positioning pin. The Y-direction positioning surface is used for contacting with the hood positioning surface to realize the Y-direction positioning of the base. Using the inspection tool to detect the thickness of the functional surface of the hood does not need to be carried out after the entire vehicle is assembled, but can directly detect the hood. Its small size allows it to detect the thickness of a single sub-assembly at any time when there is a defect in the loading of the vehicle, regardless of the location, and quickly judge the corresponding positioning and operation of the size defect of the sub-assembly and the defect of the whole vehicle.
Description
technical field [0001] The invention relates to the technical field of detection of geometric dimensions of a body in white, in particular to a rapid detection tool for the thickness of a functional surface of a hood and a detection method thereof. Background technique [0002] The detection of the functional thickness of the body-in-white hood assembly of the welding adjustment line (that is, the installation height of the functional surface of the fender) requires the use of a large-scale three-coordinate instrument to mark the detection part of the body, and then compare the difference in the mixing distance after outputting the coordinate value , to judge whether the functional thickness is consistent. This detection method needs to coordinate a large amount of resources and time to realize the detection, which is not only troublesome to operate, but also takes a long time, which is not conducive to the rapid analysis of defects. The front face detection sample rack is ...
