Problems solved by technology
The current middle-level measurement method for tailgate hanging has the following problems: the position of the end point (that is, the measurement point) of the end of the measuring ruler in contact with the tailgate is not accurately positioned. The measurement data results are different depending on the position of the point and point. When the measurement ruler is not placed flat enough, the measurement error can reach more than 1mm to 5mm, which seriously affects the accuracy and uniqueness of the measurement data results.

The invention provides a measuring point locating device for a N111 car tail gate centering degree, and belongs to a measuring point locating device for car body in white checking measurement. In the embodiment shown in the picture 4, a small locating pin (2), a small locating pin (3) and a large locating pin (4) which are firmly connected with a main body structure (1) are buckled in a rear side body tail light upper mounting hole (9), a rear side body tail light lower mounting hole (10) and a rear side body tail light lower locating hole (11) of a body in white rear side body (6) respectively to be in contact in a clearance fit mode. When a straightedge (8) makes contact with a body in white tail gate (7) through a straightedge locating slot (5) excavated in a main body support (1), only one measuring point exists, so uniqueness of the measuring point is guaranteed, and the error of a measured data result of the N111 car tail gate centering degree directly measured through the straightedge is eliminated, and the measured data result has an unquestionable accuracy and uniqueness.
Description
Technical field [0001] The invention belongs to a measuring point positioning device for inspection and measurement of automobile body-in-white. Background technique [0002] SAIC-GM-Wuling Automobile Co., Ltd.’s N111 car body-in-white tailgate hanger centering is currently used to measure the measurement personnel with a straightedge to directly measure the installation hole of the left rear side tail light and the right rear side tail light installation. The distance between the mounting holes and the inner panels on the left and right sides of the tailgate. The current middle-level measurement method for tailgate hanging has the following problems: the position of the end point (that is, the measurement point) of the end of the measuring ruler in contact with the tailgate is not accurately positioned. Depending on the position of the point, the measurement data results are also different. When the measurement ruler is not placed flat enough, the measurement error can rea...
