[0041] The storage box 6 is fixedly connected to the bottom plate 1 and is used for storing the detection pin 5 .

[0042] In this embodiment, when the hole position of a thin plate-shaped part is detected, the flap 41 is first flipped to one side to open the positioning and fixing component 2 directly; then the part 8 is positioned and fixed by the positioning and fixing component 2, and the installation operation is very convenient.

[0043] Then the flap 41 is turned back and positioned above the part 8. At this time, the detection pin 5 is passed through the detection through hole 42 on the flap 41, so that the detection head at the bottom of the detection pin 5 passes through the hole to be detected on the part 8 and is inserted into the detection pin hole on the detection seat 3. If the detection head is successfully inserted into the detection pin hole, the hole to be detected is qualified; otherwise, the hole to be detected is unqualified.

[0044] The inspection fixture part 8 of the present application is easy to install, accurately positioned, can accurately detect the position of the holes of the part 8, has high detection efficiency, and is suitable for batch detection of the part 8.

[0047] In this embodiment, after the flap 41 is opened, one side of the part 8 is pressed against the positioning block 21, and the other two sides are pressed against the positioning stop posts, and the part 8 is moved downward so that the positioning posts are inserted into the positioning holes of the part 8 to position the part. The positioning block 21 and the positioning stop posts roughly position the part 8 to ensure that the positioning posts are accurately inserted into the positioning holes, thereby improving the convenience of positioning and installing the part 8. Most thin plate-shaped parts 8 are provided with positioning holes for easy installation. If no special positioning holes are provided on the part 8, the other two holes can be selected as positioning holes to position the part 8.

[0054] In a preferred embodiment, if Figure 1 and Figure 2 As shown, a limit support plate 412 is fixedly provided on the top of the first connecting block 47. When the flap 41 is flipped open, the limit support plate 412 abuts against the outer side of the first base 43, so that the maximum flip angle of the flap 41 is 95-115 degrees, thereby preventing the flap 41 from flipping too large and improving the convenience of flipping the flap 41.

[0055] In a preferred embodiment, if Figure 2 As shown, a first positioning plate 413 is fixedly provided at the bottom of the support groove 46 to provide positioning support for the bottom of the second connecting block 48 and ensure that the second positioning hole is aligned with the first positioning hole; second positioning plates 414 are symmetrically fixedly provided on both sides of the support groove 46 to provide positioning support for both sides of the second connecting block 48 and prevent the second connecting block 48 from shaking to both sides, thereby improving the positioning accuracy of the flap 41 after installation.
