一种孔系组合夹具夹紧装置构形设计方法

An automatic approach to fixture configuration design for dowel-pin modular fixture system

介绍一种针对棱柱形工件的孔系组合夹具夹紧装置的自动构形方法。首先确定工件的夹紧区域并离散化,然后根据工件的形状确定夹紧装置的个数,进而确定候选夹紧方案,并提出夹紧方案的质量评价标准。最后通过实例验证上述方法的可行性和精确性。

A clamping design approach for automated fixture design based on dowel-pin system is presented,which accepts a polygonal and columniform description of the part silhouette. The simplifying method of the feasible clamping face of a part from the solid model is proposed. The classification of feasible clamping position of workpiece is established by making use of the reducing method of the projecting outline of part. The quality metric of clamping plan is established. A prototype system is developed to proved the algorithms involved.
