Positioning gap control contact pattern

The utility model discloses a positioning gap control contact pattern, which comprises a gap main plate and a gap auxiliary plate, wherein the gap main plate is perpendicularly intersected with the gap auxiliary plate; the gap main plate comprises a first gap backup plate and a second gap backup plate, which are positioned on the two sides of the gap auxiliary plate; the gap auxiliary plate comprises a third gap backup plate and a fourth gap backup plate, which are positioned on the two sides of the gap main plate; the first, second, third and fourth gap backup plates have different thicknesses, and the thickness of each of the first, second, third and fourth gap backup plates corresponds to the weld dimension required by one standard weld. According to the positioning gap control contact pattern, the gap main plate and the gap auxiliary plate are perpendicularly intersected, the gap backup plates have different thicknesses, and the thickness of each gap backup plate corresponds to the weld dimension required by one standard weld, so that the whole positioning gap control contact pattern can have at least four different weld gaps, the application range of the positioning gap control contact pattern is widened, and the universality of the positioning gap control contact pattern is improved.
