插销是夹具上常用的定位元件。它在钻模板的定位上用得很多,尤其是钻模板在钻模上有两个以上工作位置的钻模,几乎全用插销进行定位。一般使用的手用插销仅起定位作用,无压紧作用,为防止钻削时钻模板抬起,必须有钻模板的压紧装置。这样,不仅使钻模的结构复杂,而且增加了压紧和松开钻模板所需的辅助时间。为提高生产率,简化钻模板定位压紧机构,方便操作,我厂设计和制造了一种新颖的自压紧插销,介绍如下: 结构及使用自压紧插销的结构如附图所示。圆柱销压配在销 Pin is commonly used on the fixture positioning components. It uses a lot of positioning of the drilling template, in particular the drilling template has more than two drilling positions on the drilling die, almost all with pins for positioning. The general use of hand-pin only from the role of positioning, no pressure effect, in order to prevent the drilling template raised when drilling, drilling template must be pressed device. In this way, not only the structure of the drill die is complicated, but the additional time required for pressing and releasing the drill die plate is increased. In order to increase the productivity, simplify the positioning and pressing mechanism of the drilling template, and facilitate the operation, our factory designs and manufactures a novel self-compacting latching pin, which is introduced as follows: The structure and the structure of the self-aligning latching pin are shown in the attached drawings.
