| Zusammenfassung: | A positioning pin size detection tool is used for detecting a positioning pin, the positioning pin comprises a cylindrical part and a pin head part, the pin head part is provided with two parallel clamping surfaces, the outer circle diameter of the cylindrical part is between D1 and D2, the distance between any clamping surface and the axis of the cylindrical part is smaller than or equal to D3, and when the distance between the clamping surface and the axis of the cylindrical part is D3, the positioning pin with the eccentricity smaller than or equal to D4-D3 is a qualified piece. The positioning pin size detection tool comprises a first cylindrical hole, a second cylindrical hole and a pin head clamping groove, the inner diameter of the first cylindrical hole is D2, the inner diameter of the second cylindrical hole is D1, a first detection surface and a second detection surface which are parallel are arranged in the pin head clamping groove, the distance between the first detection surface and the axis of t |
