Description

Technical Field

[0001] This utility model belongs to the field of aviation industry manufacturing and relates to a riveting device for bracket parts for aircraft engines. Background Technology

[0002] In the aviation field, the aircraft engine, as the "heart" of the aircraft, directly affects flight safety and overall operational efficiency through its stable and reliable performance. Support components, as key parts of the aircraft engine, undertake important functions such as support and fixation. Their delivery requirements are extremely stringent, demanding not only near-zero defect standards for delivery quality but also strict limitations on production cycles. On-time delivery is essential to ensure the overall assembly progress and production rhythm of the aircraft engine.

[0003] Among them, aircraft engine bracket parts have special shapes and complex structures, and the installation space for the bracket nuts is narrow, which brings great difficulties to the processing technology. In the existing processing methods, in order to ensure the riveting quality, workers usually need to use hand rivet guns to rivet the parts. Because it is difficult for workers to be completely precise and consistent in their operation, the rivet heads are prone to developing undesirable shapes such as "trumpet shape", "cone shape" or "horseshoe shape", resulting in unstable product quality, high defect rate, and extended production cycle. Utility Model Content

[0004] The purpose of this utility model is to provide a riveting device for bracket parts of aero-engines, so as to solve the technical problem of unstable riveting quality of aero-engine bracket parts.
