摘要:: 针对某超长条结构件加工过程中由于使用传统工装夹具造成的工艺准备时间长、工装数量多、材料浪费严重等问题，开展一种柔性工装平台的研究。该工装平台采用多个可旋转夹臂替代传统夹具进行夹持，在工件外形变化时，可通过更换夹臂长度、按压角度等保持良好夹持效果，满足柔性工装的需求。对该工装平台结构进行设计，对关键参数进行建模和校核，通过样机对工装效果进行验证。结果表明，该工装平台在加工相同工件的情况下，可节省约3%的零件材料，缩短310 min工艺准备时间，同时由于该工装平台采用了新型柔性固持方案，还提高了加工连续性，避免由于工艺变化造成大量的夹具浪费，为超长条结构件的加工提供了一种新的工装固持方案。

Abstract:: A flexible tooling platform was developed to address the problems of long process preparation times,high tooling quantities and material wastage caused by the traditional tooling process during the machining of extra-long strip workpieces.The tooling platform uses multiple rotatable clamping arms instead of traditional fixtures for clamping.When the shape of the workpiece changes,the clamping effect can be ensured by changing the length of the clamping arm,the pressing angle,etc.to meet the needs of flexible tooling.In this paper,the structure of the tooling platform was designed,the key parameters were modelled and checked,and the effect of the tooling was verified by a prototype machine.The results show that the tooling platform can save approximately 3% of the part material and shorten the process preparation time by 310 min for the same workpiece.At the same time,the use of the new flexible clamping technology also improved machining continuity and avoided a lot of fixture waste due to process variations,which provides a new way of tooling clamping for the machining of extralong strip workpieces.
