液性塑料心轴的设计与试验研究

Design and Test Study of Liquid Plastic Core Axle

弹性心轴是一种外涨式的自动定心夹具,它利用定位-夹紧元件的均匀弹性变形来实现对工件的无间隙定位,其设计和制造较为困难。本文针对传动装置中框架类零件加工精度难以保证的问题,对其中一种典型零件选用液性塑料涨开心轴作为设计方案,进行了液性塑料心轴的设计、性能分析、参数优化、加工制造和试验研究,摸索出了可行的工艺方案,满足了零件的加工精度。

Elastic core axle is a kind of extended automatic attentive fixtures, which realizes non-space orientation by using even and elastic deformation of orientation clipping elements with hard design and manufacture. This paper chose liquid plastic extended core axle as design plane for a typical pieces, which mainly aimed at the problem that the precise of frame pieces of transferring equipments, did the design of liquid plastic core axle, analysis of ability, parameter optimization, manufacture and test research, found out the feasible process plane, met the needs of manufacturing precise of pieces.
