Problems solved by technology

During this process, if gravity, autoclave pressure, etc. act on the left and right sides of the T-shaped stringer and the external forces are unbalanced, the stringer will move under the drive of the force, and a long string will inevitably appear after the glue is solidified. The problem of excessive tolerance of truss axis axis

Abstract

The invention provides a detachable and adjustable long truss clamping and positioning device and a positioning method. The positioning device comprises a positioning and pressing device, an angle base, a positioning clamping base and a bracket. The positioning and pressing device consists of a rotating wheel, a lead screw, and a glaze pressing block made of a buffer material. During working, longtrusses are placed through positioning clamping plate gaps; then, the rotating wheel is rotated to drive the lead screw to move in a limiting hole to push the glaze pressing block; the glaze pressingblock is slowly contacted with web surfaces of the long trusses; and the long trusses are gradually pressed to a positioning reference surface. The manufacturing flow is simplified; the long truss positioning is decomposed to two steps of placement and clamping; and the operability is high.

Description

technical field [0001] The invention relates to the technical field of manufacturing aircraft composite parts, in particular, it can be used for a pressing and positioning device and a positioning method for stringers with different thicknesses and curvatures. Background technique [0002] The integrally reinforced panel of composite material simplifies the assembly relationship of aircraft structure, reduces the use of fasteners, reduces the weight of aircraft structure, increases the maintainability of aviation aircraft, and improves the economic benefits of aircraft operation. Therefore, the integrated manufacturing technology of composite parts (groups) has become the development trend of the industry. T-shaped reinforced wall panel is a structural form of composite material reinforced integral wall panel. It usually consists of a skin and several T-shaped stringers. In order to ensure the comprehensive performance of the product and meet the subsequent assembly requir...
