飞机结构件的数控加工,应有柔性夹具作为加工质量和加工效率的保证。成组夹具和拼装夹具是实现柔性夹具的重要手段。计算机辅助夹具拼装规划、夹具生产流程管理是柔性夹具系统中的重要功能模块,必须得到较好的解决。柔性夹具一般应具备气动或液压夹紧功能,并与数控机床在结构和控制上集成为一体。 Aircraft structural parts of CNC machining, flexible fixture should be as a guarantee of processing quality and processing efficiency. Group fixture and assembly fixture is to achieve an important means of flexible fixture. Computer-aided fixture assembly planning, fixture production process management is an important functional module in the flexible fixture system, we must get a better solution. Flexible fixture should generally have pneumatic or hydraulic clamping function, and CNC machine tools in the structure and control integration as one.
