检验两个以上孔间的距离,普通用定梢样板。定梢间的距离准确度,决定于样板本体上定梢孔距的准确难度。这种装置有严重的缺点: 首先,制造此种样板必须有相当精度的机床。其次,为了压合定梢,孔径精度须高。再者样板本体不能经热处理,故使用时磨损增加,磨损后样板在多数情况下也不能翻新重用。斯大林汽车工厂工程师格、恩、白普心创造了一种新的设计,既无上述缺点,成本也降低很多。如所示,在经过淬火后的样板本体上,有两道磨制成90°形的
Test the distance between more than two holes, the general use of pin-up model. Set the distance between the accuracy of the decision on the template body Dingzuo pitch accurate accuracy. There are serious drawbacks with this device: first, a very high precision machine tool must be manufactured to produce such a model. Second, in order to press the fixed pin, the aperture accuracy must be high. Furthermore, the body of the model can not be heat treated, so the wear increased when used, wear the model in most cases can not be refurbished reuse. Stalin Automotive Plant Engineer Ge, Ernst & White Pu Xinxin created a new design that suffers neither of the above shortcomings and costs much lower. As shown, on the body of the sample after quenching, two mills are formed into a 90 ° shape
