Location mechanism for airplane stringer

The utility model relates to airplane manufacture technology and provides a novel location mechanism for an airplane stringer and particularly for location of the airplane stringer. The location mechanism for the airplane stringer is characterized by comprising a stringer tightly-pressing device and a stringer location plate. The stringer location plate is provided with a set of stringer location groove openings. The stringer tightly-pressing device is fixed on the stringer location plate. A stringer tightly-pressing point on the stringer tightly-pressing device coincides with a stringer location groove opening point on the stringer location plate. The location mechanism for the airplane stringer has the advantages that structure is light in weight and exquisite, the weight is no more than 1 kilogram, use is flexible, better generality is possessed, the number of special location tightly-pressing devices used by a traditional plate assembly clamp device is reduced, and a solution is provided for places where space is small and the special location tightly-pressing devices can not be arranged.
