Abstract

The invention discloses a profile stretch bending device for aircraft manufacturing, and relates to the technical field of aircraft profile machining. The profile stretch bending device particularly comprises a base, a pressing mechanism, a clamping mechanism and a detecting mechanism. A mounting rack is welded to the outer wall of one side of the base, and the pressing mechanism comprises a hydraulic cylinder and a bending head. The hydraulic cylinder is fixedly mounted on the outer wall of the top of the mounting rack through a bolt. The output end of the mounting rack is fixed to the outerwall of the top of the bending head. The clamping mechanism comprises two connecting arms, two connecting frames, two first clamping plates and two second clamping plates. According to the profile stretch bending device, the pressing mechanism is arranged, and therefore a profile can be bent; the clamping mechanism is arranged, and therefore the two ends of the profile can be clamped, and the workstability is guaranteed; the first clamping plates are mounted on the inner walls of the connecting frames through shafts and bearings, and therefore the angle can be changed in real time when the profile deforms; and the profile is prevented from being damaged, and meanwhile the service life of the device is prolonged

Description

technical field [0001] The invention relates to the technical field of aircraft profile processing, in particular to a profile stretch bending device for aircraft manufacturing. Background technique [0002] With the development of science and technology, transportation is becoming more and more developed, and people's lives have become more convenient. As a fast and efficient means of transportation, airplanes are also widely used by people. In the manufacturing process of airplanes, the processing of its profiles is inevitable. Profile stretch bending devices are used, and some profile stretch bending devices have low reliability and the use effect is not ideal. [0003] After searching, the Chinese patent application number is CN201410708666.2, which discloses a metal profile stretch bending device, which is used to stretch and bend metal profiles. surface; the clamping and bending part, including: the clamping part for clamping the metal profile, and the stretching and ...
