本课题是橡胶成形件自动修剪机夹具及传动部分的设计，包括机械手的设计，自动上料、下料机构设计，自动切削部分设计。在夹具部分设计中，分析了两种方案，一种是采用机械夹紧方法，另一种是采用气体负压夹紧。考虑多种因素采用了气体负压夹紧。夹具设计合理，精度合适。在传动部分，传动方式采用了带传动，方案结构简单，成本低。在机械手的设计过程中分析到机械手末端两种方式，采用了一个气爪一个电磁铁的方案。在传感器的设计部分中，采用了光电传感器和电磁式传感器。本课题设计的夹具及传动部分，方案合理，结构紧凑。完成了自动修剪机夹具及传动部分设计指标要求。设计的机器能够完成切削范围：20—50，切削效率：15-20个/分钟。这种橡胶成形件自动修剪机的大量生产，能够提高加工效率，增加利润。 关键词：密封圈；修剪机；夹具；传动 The jig a
