工艺孔在一些夹具的制造中是十分有用的。合理设计工艺孔,不仅能够简化坐标的计算,而且也便于夹具制造和测量。工艺孔应用实例很多,且设计、计算的方法又不尽相同。现就几种情况简介如下。一、利用工艺孔作定位基准,用于加工斜孔钻模斜孔钻模是一种常见的钻床夹具。这类夹具在制造时一般都需要设计工艺孔。 Craft holes are very useful in the manufacture of some fixtures. Reasonable design of the process hole, not only to simplify the calculation of coordinates, but also easy to manufacture and measure fixtures. There are many application examples of process holes, and the design and calculation methods are different. Now on a few situations are as follows. First, the use of technology as a benchmark for positioning holes for processing oblique hole drilling Diagonal hole drilling is a common drilling fixture. Such clamps are generally required in the manufacture of the design process hole.
