Detailed Implementation

[0016] The present invention will be further described in detail below with reference to the accompanying drawings.

[0017] Example 1

[0018] like Figure 1 , Figure 2 The embodiment of the present invention shown includes: an acrylic plate 1, an irregularly shaped through hole 2, a part to be measured 3, a measuring camera 4, and a base 5. The acrylic plate 1 is fixed on the base 5, and the irregularly shaped through hole 2 is opened on the acrylic plate 1. The part to be measured 3 is placed in the irregularly shaped through hole 2, and the measuring camera 4 is arranged above the irregularly shaped through hole 2.

[0019] The irregular through-hole 2 includes: a large rectangular opening 201, a first small rectangular opening 203, and a second small rectangular opening 202. The length and width of the large rectangular opening 201 match the length and width of the bottom outer contour of the measured part 3. The first small rectangular opening 203 and the second small rectangular opening 202 are located on the third side of the large rectangular opening 201. The fourth side of the first small rectangular opening 203 and the second small rectangular opening 202 are connected to the large rectangular opening 201 at the first side edge line 205. The width of the first small rectangular opening 203 and the second small rectangular opening 202 are respectively matched with the protrusion height of the insulator-side boss 302 and the connector-side boss 301 of the measured part. The first small rectangular opening 203 shares the same first side edge line 205 as the large rectangular opening 201, and the second small rectangular opening 202 shares the same second side edge line 206 as the large rectangular opening 201.
