[0035] In this example, the base plate 1 is equipped with multiple pin holders 9, and each pin holder 9 has a detection pin 7, a scribing pin 8, and a surface difference gauge 11. The base plate 1 is also equipped with a go / no-go gauge 10.

The go / no-go gauge 10 and the surface difference gauge 11 are used to detect the contour of the mounting surface of the nut hole, the mounting surface of the rotating arm, and the cut edge. The pin holders 9 are fixed to the base plate 1 with screws.

[0036] Working principle: When using this automotive hood hinge assembly inspection fixture, first move the inspection component 5 to the outermost non-working state (e.g., Figure 3 (As shown), open the clamping device 202 of the flipping detection assembly 4, clamping assembly 6, and positioning clamping assembly 2. Then, align the car engine hood hinge assembly part to be tested with the main positioning pin 203 and place it on the inspection fixture. Insert the auxiliary positioning pin 204. Then, close the clamping device 202 of the positioning clamping assembly 2 to clamp the part to be tested and rotate the part's rotating arm to the closed position. Then, close the flipping detection assembly 4 to the detection position and push the quick clamp 602 of the clamping assembly 6 upwards so that the clamping block 603 clamps the part to be tested. At this time, the part in the closed state can be tested. Insert different detection pins 7 and scribing pins 8 into the nut hole detection part 3 and the mounting hole on the rotating arm respectively to detect the position accuracy of the nut hole and the mounting hole on the rotating arm. Use the go / no-go gauge 10 and the surface difference gauge 11 to detect the contour of the nut hole mounting surface, the rotating arm mounting surface, and the cut edge. After the closed part is tested, open the flipping detection assembly 4 and the clamping assembly 6. Figure 4The image shows the state when the hinge is at its maximum open angle. The moving detection component 5 is slid to the detection position and the limit pin 505 is inserted. Then, the part rotating arm is rotated to its maximum angle. The hinge rotating arm can rotate around the hinge rotation axis (e.g., ...). Figure 13 As shown at point e), the second zero-contact surface 5011 on the detection block 5010 is aligned with the mounting surface of the rotating arm of the part. At this time, the position accuracy of the mounting holes on the rotating arm can be checked using the detection pin 7 and the scribing pin 8. The contour accuracy of the mounting surface and cut edge of the rotating arm can be checked using the go / no-go gauge 10 and the surface difference gauge 11. In addition, the deviation value of the maximum angle of the rotating arm can be determined by observing the scale position on the angle block 509 pointed to by the tip of the second tilting arm 508, and checking whether it is within the tolerance range required by the drawing (e.g., ...). Figure 11 As shown), after the test is completed, slide the moving test component 5 to the outermost side, open the clamp 202 on the positioning and clamping component 2, remove the secondary positioning pin 204, and remove the part. This completes the entire work. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
