随行夹具的夹紧机构,不同于普通机床夹具的夹紧机构。普通机床夹具的夹紧机构,是将工件牢固地压紧在夹具的定位面上,而随行夹具的夹紧机构,为了要保证夹具的随行动作,不能将工件夹紧固牢,其夹紧件和定位支承件对工件来讲,应是如图1所示的弹性夹紧和弹性支承(有时也采用固定支承)。笔者从所经过的几代产品夹具设计资料中,选择了几种夹紧机构,仅供参改。
Accompanying fixture clamping mechanism, different from the ordinary machine tool clamping mechanism. Ordinary machine tool clamping mechanism, the workpiece is firmly pressed on the positioning surface of the fixture, and follow the fixture of the clamping mechanism, in order to ensure follow-up movements of the fixture, the workpiece can not be firmly clamped, the clamping member And the positioning support for the workpiece, it should be flexible clamping and elastic support as shown in FIG. 1 (sometimes using fixed support). I passed several generations of product fixture design information, select a few kinds of clamping mechanism, for reference only.
