Middle wing part gluing and folding tool for small and medium-sized unmanned aerial vehicles

Abstract

The invention discloses a middle wing part gluing and folding tool for small and medium-sized unmanned aerial vehicles. The middle wing part gluing and folding tool consists of a rotating support, a base, a pressing frame and positioners mounted on the base. The rotating support is used for supporting the rotating base and the pressing frame, and combination and separation of the rotating supportand the base can be rapidly achieved through insertion and extraction of the pin shaft. The base is used for supporting the lower plate and positioning and installing the positioners. The pressing frame is used for positioning the upper plate and measuring the gap, and uniformly applying cementing pressure. The horizontal measuring point positioner is used for drilling holes in the front edge andthe rear edge of the middle wing part and positioning horizontal measuring points. The middle wing front-back connector positioner is used for positioning a middle wing front-back connector and servesas a connector hole finish machining platform to eliminate assembly stress. According to the middle wing part gluing and folding tool, tolerance distribution is reasonably carried out, the gluing gapand the gluing pressure are controlled, and the product manufacturing precision and the gluing reliability are improved through rotation of the mold; finish machining is carried out before the product is taken off the rack, the assembly stress is eliminated and the parts are enabled to meet the interchangeability requirement.

Description

technical field [0001] The present invention relates to the technique of closing the wing parts of unmanned aerial vehicles, in particular to a folding tool for the wing parts of small and medium-sized unmanned aerial vehicles. Background technique [0002] At present, most parts of the UAV body are made of non-integrated composite materials, and the connection between parts is made of glue, which not only reduces the weight of the UAV, improves the performance index of the UAV, but also effectively reduces the number of parts and fastening. number of pieces, reducing production costs. [0003] Invention patent CN103101632 B discloses "a modular closing tooling platform for unmanned aerial vehicle body and its use method". The tooling is based on the cast iron basic platform, and through modular combination design, it can be quickly assembled according to the structural characteristics of different bodies to meet the needs of the development stage. The rapid and changeable ...

Problems solved by technology

However, when the UAV is produced after it is finalized, its shortcomings are undoubtedly revealed. Its size chain has many links, the cumulative error is large, and the positioning accuracy of the aircraft joint parts is low, which affects the overall performance of the aircraft; the bonding pressure is uneven, the bonding strength is scattered, and reliable. Poor performance; only local positioning of the UAV’s appearance is performed, and the accuracy of the aircraft airfoil is low; the tooling is heavy and cannot be turned over, and cavities are easily formed when the upper surface is glued, and the quality of the glue cannot be guaranteed; the heat capacity is large, and it is difficult to move. Can only be cured at room temperature, long production cycle
