摘要
针对航空领域中翼类结构件的高速铣削加工,提出一种干涉小、柔性高、换装快速、自动化程度较高的夹具设计方案。详细论述了该夹具系统的组成、原理以及PLC控制程序。采用可调式定位板定位、回转夹紧气缸夹紧,利用传感器感知、PLC控制以实现电磁阀有序动作、工件可靠夹紧,解决传统装夹中原材料浪费和加工过程中机床刀具与夹具的干涉问题。编制了相应控制程序并调试成功。该夹具设计方案为飞机结构件实际生产和程序控制自动化夹具设计提供了有效的参考依据。
Aiming at the high speed milling of the wing structure in the aviation field, a fixture design scheme with small interference, high flexibility, fast changing and high automation is proposed in this paper. The composition, principle and PLC control program of the fixture system is discussed in detail. In order to solve the problem that the waste of raw materials in the traditional folder and interference between machine tool and fixture in processing, adjustable positioning plate positioning, rotary clamping cylinder clamping, the use of sensor perception, PLC control achieve the electromagnetic valve orderly action and the workpiece reliable clamping in this paper. Correspondingly, the PLC control program is edited successfully. The fixture design can be used in the actual production of the aircraft structural components and the design of the automatic control fixture.
