采用成组夹具进行零件的机械加工,是为适应多品种、小批量的形势而发展起来的,它是成组技术的基本组成部分。实践证明,成组夹具收效快、易推广。它属于可调整夹具范畴,其特点是通过少量夹具元件或组件的更换、调节,使一套夹具能有几套夹具的功能,可当作不同的专用夹具来使用。它适于结构、形状、定位夹紧方式相似的一组零件的工艺加工。
The use of group fixture for machining parts is to adapt to the variety and small quantities of the situation developed, it is an integral part of group technology. Practice has proved that the group of fixtures fast, easy to promote. It belongs to the scope of adjustable clamps, which is characterized by a small amount of fixture components or components replacement, adjustment, so that a fixture can have several sets of fixture functions, can be used as a different special fixture to use. It is suitable for structure, shape, positioning clamping a similar way a group of parts of the process.
