Abstract

The invention discloses a curve or distortion detection and prestressing force infliction experiment table for a composite material C-type beam. The curve or distortion detection and prestressing force infliction experiment table for the composite material C-type beam comprises an experiment table bottom platform, a longitudinal positioning check block as well as a force-applying device arranged on the experiment table bottom platform, an edge left side horizontal positioning device, an edge right side horizontal clamping device and a longitudinal positioning device, wherein a first longitudinal positioning check block and a second longitudinal positioning check block are respectively arranged on the edge left side horizontal positioning device and the edge right side horizontal clamping device in a sliding manner. The curve or distortion detection and prestressing force infliction experiment table for composite material C-type beam provided by the invention has the characteristics that a beam piece is subjected to shape surface detection and manufacturing error correction, the deviation adaptability is strong for large-scale and different C-type beams, the structure is relatively reasonable, the positioning is stable and the like, the positioning device is utilized for finishing the clamping positioning of the C-type beam, the experiment table can carry out the shape surface detection on beam pieces with different deviations after manufacturing is finished, a certain manufacturing error operation is corrected through the stress of the force-applying device, the beam pieces with different deviations meet the assembling requirements, and the assembly of the composite material C-type beam is finished.

Description

technical field [0001] The invention relates to the technical field of aircraft manufacturing and assembly, in particular to a composite material C-shaped beam bending and twisting detection and prestressing test bench. Background technique [0002] The composite C-beam is used in the front spar structure of the rudder in aircraft manufacturing, and is considered to be the key to controlling the flight of the aircraft, and its length can reach about 2m. Since the composite material uses a layered structure, it is difficult to form it as a whole, and it is difficult to correct the manufacturing deviation. [0003] In the process of testing the surface of composite C-beams, we generally believe that the direct surface meets the requirements of the deviation itself, and the two types of composite C-beams that meet the design requirements after applying a certain prestress to deform are Qualified product. Therefore, it is extremely necessary to invent a tool that can detect th...
