[0074] Embodiment three

[0075] With reference to the accompanying drawings Figure 5 Embodiment three of the present application provides an outer panel positioning and measuring method, which comprises:

[0076] Step 201, insert two positioning pins 2 into the positioning holes of the inner panel of the door, and support the four inner panel support points of the inner panel through the support surfaces 32a of the four support pieces 3;

[0077] Step 202, establish the inner panel reference coordinate system according to the support body;

[0078] Step 203, measure the four Y-direction reference points of the outer panel of the door, obtain the deviation values of the four Y-direction reference points, find the inner panel support point of the door inner panel corresponding to the Y-direction reference point that needs to be adjusted, and insert a gasket 35 corresponding to the deviation value into the corresponding support piece 3 to support the inner panel support point through the support end 33a of the movable support part 33;

[0079] Step 204, measure the deviation values of the four Y-direction reference points again until the deviation value of each Y-direction reference point is adjusted to meet the tolerance requirement;

[0080] Step 205, measure the X-direction reference points and Z-direction reference points of the outer panel of the door and establish the outer panel reference point coordinate system, and measure the door assembly 4.

[0081] Specifically, the method provided by the embodiment is applied to the door measuring support described above, and is used for positioning and auxiliary measuring the door assembly 4 with the outer panel of the door as a positioning reference. Since the door measuring support described above is designed and developed according to the inner panel of the door assembly 4, the same steps as the inner panel positioning are first adopted to establish the inner panel reference coordinate system according to the support body. Since the deviations of the door assembly 4 based on the inner panel positioning are all reflected in the outer panel of the door, the four Y-direction reference points of the outer panel are measured in the inner panel reference coordinate system, and the deviation values of the four Y-direction reference points are obtained. The inner panel support point of the door inner panel corresponding to the Y-direction reference point that needs to be adjusted is found. The adjustable support piece 3 is adopted, a gasket 35 corresponding to the deviation value is inserted into the support piece 3, and the support end 33a of the movable support part 33 supports the inner panel support point. For example, if the deviation of one Y-direction reference point is 0.7 mm after measurement, a gasket 35 of 0.7 mm is inserted into the support piece 3 supporting the inner panel support point corresponding to the Y-direction reference point. The deviation values of the four Y-direction reference points are measured again. If it is unqualified, the adjustment is continued through the adjustment of the gasket 35 until the deviations of the four Y-direction reference points meet the tolerance requirements of the outer panel RPS reference points. After the four Y-direction reference points are adjusted, the X-direction reference points and Z-direction reference points of the outer panel of the door are measured. The plane is determined through the four Y-direction reference points, the straight line is determined through the two Z-direction reference points, and the origin is determined through the X-direction reference point. The outer panel reference coordinate system with the outer panel of the door as the reference is established by using the iterative method, and the door assembly 4 is measured. The collected measurement data can more intuitively reflect the size problem of the door assembly 4 after being assembled to the door.
