Abstract

The invention relates to automatic hole forming equipment for composite airfoil components. The automatic hole forming equipment is five-axis linkage numerically controlled equipment, and comprises a main rack, a B-axis support, an A-axis rotary table, a Z-axis subassembly, a Y-axis drag chain, a Z-axis drag chain, a scrap suction device, a knife lubricating system and an oil pump of the lubricating system, wherein a spindle is arranged on the Z-axis subassembly; a component knife which can be used for drilling holes, reaming holes and reaming pits is hydraulically clamped on the spindle; four laser distance measuring sensors are symmetrically arranged at ends of the Z-axis subassembly and are distributed on four quadrants; a pressure foot support is arranged below the Z-axis subassembly; and pressure feet are arranged on the periphery of a center hole of the pressure foot support, and are provided with pressure foot sensors. By using the automatic hole forming equipment and the hole forming method, the clamping and positioning precision is high, the accuracy of formed holes is high, and damage to composites in a hole forming process is reduced, so that the quality of a product is improved while the work efficiency is improved.

Description

technical field [0001] The invention relates to an automatic hole-making device and a method thereof for airfoil components of composite materials, and is provided with a fully automatic numerical control machining method. Background technique [0002] After the 1990s, the aviation manufacturing industry put forward high-quality, high-efficiency, low-cost production requirements for aircraft assembly technology that can adapt to a variety of products. As an effective way to improve assembly efficiency and assembly quality, the automatic hole-making method is increasingly in demand and development trend. Although the conventional five-coordinate automatic hole-making method has the functions of five-axis linkage, normal adjustment, and hole-making accuracy detection, it still cannot meet the requirements of large-size, variable-thickness, and complex interlayer composite airfoil parts. need. Improve the automatic hole making process to reduce the splitting and delamination ...
