在批量生产中,为了保证制件在某一方向的重复定位精度,常常要为它设计、制造必要的止动装置而花费很大的精力。为了追求经济效益,特介绍如下三种通用性较好、结构简单、使用方便的止动装置。希望有助于解决这方面的问题。一、虎钳止动装置(图1)该装置适于一些零件在钻孔、镗孔和铣削端面到尺寸等工序。为适应不同工件的要求,其止动螺钉可以在一定范围内通过绕安装螺孔中心线旋转而调整。止动螺钉端头作成半球形,是为了与制件的接触点总保持在一个固定的地方。二、可调整的工作台止动装置
In mass production, in order to ensure that parts in a certain direction of the repeated positioning accuracy, often for it to design, manufacture the necessary stop device and spend a lot of energy. In pursuit of economic benefits, special introduction to the following three generality, simple structure, easy to use stop device. Hope to help solve this problem. A vise stop device (Figure 1) The device is suitable for some parts in drilling, boring and milling end to size and other processes. In order to meet the requirements of different workpieces, the stop screw can be adjusted within a certain range by rotating around the centerline of the mounting screw hole. Stop screw ends made of hemispherical, is to keep contact with the workpiece in a fixed place. Second, the adjustable table stop device
