Description

Technical Field

[0001] The utility model relates to the technical field of positioning tooling, in particular to a long stringer handover positioner for a composite product. Background Art

[0002] The long stringer is made of composite materials and is a longitudinal member of the aircraft fuselage structure. Among aviation parts, many parts are slender. In order to reduce the cost of part processing, they are often processed with profiles, which will reduce the raw material weight and processing time of the parts. However, since the profiles are easy to deform, it is difficult to clamp during processing and the size of the parts cannot be guaranteed. Tooling is required to solve the problems of difficult part clamping and long positioning time, improve processing quality and production efficiency, and reduce production costs. Generally, for reinforced wall panels with a length of less than 2 meters, the positioning devices of the long stringers are usually set at both ends of the long stringers. The long stringer positioning device positions the long stringer when it is glued to the skin, and on the other hand, it limits the movement of the long stringer during the curing process of the part.

[0003] In the existing technology, a locking and positioning tool for a long beam component with a publication number of CN214490245U is proposed, which includes a base, a reference block, a clamping and locking device, and a positioning device; the reference block can be detachably mounted on the base, and is used to determine the positioning reference of the long beam component according to the shape of the part; the clamping and locking device can be detachably mounted on the base, and is used to lock the part during processing; the clamping and locking device includes a pad and a pressure plate; the pad is fixedly connected to the base, and is used to clamp the lower part of the long beam component and the reference block; the pressure plate is fixedly connected to the pad and the long beam component, and is used to clamp the upper part of the long beam component between the pad and the reference block; the positioning device includes a plurality of lateral reference plates, and the lateral reference plates are fixedly connected to both sides of the upper part of the base, and are used to unify the positioning reference during clamping. This application realizes rapid clamping, ensures the repeated positioning accuracy of parts, ensures stable processing quality, and solves the problems of difficult and time-consuming part clamping.

[0004] In order to solve the problem that most of the long stringer positioning tools have a set of positioning tooling and fixtures for each long stringer component, the tooling design and manufacturing time is long, and each time the long stringer component structure has different degrees of design changes, the structure of the matching positioning tooling and fixture also needs to be modified accordingly, resulting in the problem that parts clamping is difficult and time-consuming. The prior art uses a clamping and locking device to deal with it, but there is still a situation where the original mold and the handover long stringer tooling cannot be shared, the positioning effect is not ideal, and the positioner has certain limitations, which leads to the problem of reduced utilization efficiency of the positioner.
