扭力臂是飞机起落架的重要结构件,根据其结构相似的特点,在结构、数据分析的基础上利用成组技术将扭力臂系列结构件归类;应用模块化、柔性化夹具的设计,实现热处理前扭力臂系列结构件外形加工的快速定位、找正与装夹;降低该系列化零件的装夹时间、夹具数量和设备占用,减轻数控操作工的劳动强度。 The torsion arm is an important structural part of the landing gear of the aircraft. According to the similar features of the structure, the torsional arm is classified into the structural parts based on the structure and the data analysis. The design of the modular and flexible fixture is realized Before heat treatment, the structure of torsion arm structure can be rapidly located, fixed and clamped. It can reduce the clamping time, the number of fixtures and the equipment occupancy, and reduce the labor intensity of the CNC operator.
