[0021] Example 1
[0022] like Figure 1-3As shown, the tooling structure 10 for detecting the fender opening size of this embodiment includes a tooling body 101, which is a rod-shaped body. Positioning components are symmetrically arranged on both sides of the tooling body 101, and detection components are symmetrically arranged on both ends of the tooling body 101. The positioning component is fixed to the tooling body by fasteners, and the detection component is fixed to the tooling body by fasteners. Positioning blocks 102 are arranged at both ends of the positioning component, and the positioning blocks 102 are fitted with the longitudinal beam profile to provide Z-direction positioning for the tooling structure; a positioning pin 103 is arranged in the middle of the positioning component, and the positioning pin 103 is inserted into the upper mounting hole of the longitudinal beam to provide X-direction and Y-direction positioning for the tooling structure. The detection component includes a detection block 104, a first detection pin 105 and a second detection pin 106. The detection block 104 serves as the Y-direction detection reference of the fender, and the first detection pin 105 and the second detection pin 106 are used to measure the Y-direction deviation of the fender opening area. The first detection pin 105 and the second detection pin 106 are disposed in the pin shaft hole.
[0023] like Figure 4-5 As shown, the fender opening size detection tool 10 is placed on the vehicle body cabin longitudinal beam 20 by manually holding the tool body 101. When the fender opening size detection tool 10 is placed, it is stably positioned on the vehicle body cabin longitudinal beam 20 through the positioning block 102 and the positioning pin 103. First, the fitting state of the positioning block 102 and the cabin longitudinal beam 20 is confirmed, and then the Y-direction profile of the left and right fenders 30 is measured through the detection block 104, the first detection pin 105 and the second detection pin 106, and the measurement data is analyzed. If the measurement data exceeds the requirement, measures are taken to control the deviation state of the fender opening.
