航空航天内六角螺钉保险丝孔专用加工设备的改进设计

Aerospace hexagon socket screw fuse hole improved design of special processing equipment

针对航空紧固件内六角螺钉保险丝孔(多为镍钴钛材料)加工易磨损、易断、加工成本高和效率低等特点,选用高速电火花数控小孔机床进行改进。基于三菱FX3U系列PLC,设计开发了航空紧固件内六角螺钉保险丝孔自动送卸料夹持分度装置,具有内六角螺钉保险丝孔加工中自动送卸料、自动夹持以及按要求分度功能,解决六角螺钉保险孔难以加工的问题,大大地提高了生产效率。

In view of the characteristics of aviation fastener hexagonal screw fuse hole(mostly nickel cobalt titanium material)which is easy to wear,easy to break,high processing cost and low efficiency.The high-speed EDM numerical control small hole machine tool is selected for improvement.Based on Mitsubishi FX3U series PLC,the automatic feeding and unloading clamping and indexing device for the hexagonal screw fuse hole of aviation fasteners is designed and developed.It has the functions of automatic feeding and unloading,automatic clamping and indexing according to requirements in the processing of hexagonal screw fuse hole,solves the problem that the hexagonal screw fuse hole is difficult to process,and greatly improves the production efficiency.
