[0026] Reference Figures 1 to 4 A vehicle auxiliary instrument panel upper decorative panel inspection fixture includes a cast aluminum base plate 1, a first detection part 2, a second detection part 3, a stop gauge (not shown), and a flush ruler (not shown). The first detection part 2 and the second detection part 3 are symmetrically arranged on the cast aluminum base plate 1, and are used to detect the left and right upper decorative panels. The stop gauge detects the gap between the upper decorative panel and the detection block 72 or the simulation block 5, and the flush ruler is used to detect whether the surface difference is within the tolerance range. The first detection part 2 and the second detection part 3 both include a plurality of support frames 4, and the support frames 4 are fixedly arranged on the cast aluminum base plate 1. The support frames 4 are provided with simulation blocks 5, positioning mechanisms 6, push-pull detection mechanisms 7, and detection pins 8. The simulation blocks 5 match the upper decorative panels, the positioning mechanisms 6 are used to position and fix the upper decorative panels, the push-pull detection mechanisms 7 detect the upper decorative panels by moving forward and backward, and the detection pins 8 are used to detect the hole positions of the upper decorative panels.

[0027] The cast aluminum base plate 1 is provided with a reference hole 11, a pin seat 12, and a support foot 13. The reference hole 11 is used for three-coordinate detection and positioning, and the plurality of pin seats 12 are used to insert locking pins 63, fixing pins 73 and other pin bodies. The support foot 13 is arranged at the bottom of the cast aluminum base plate 1 for support.

[0028] The positioning mechanism 6 includes two pull-wire switches 61, multiple positioning columns 62, and multiple locking pins 63. The pull-wire switch 61 includes a quick clamp, a pull wire connected to the quick clamp, and an openable and closable contoured buckle connected to the pull wire. The contoured buckle is adapted to the upper decorative panel. The positioning column 62 can be inserted into the hole of the upper decorative panel for positioning, and the locking pin 63 can fix the upper decorative panel.
