我车间在多年加工组装模具中,常常遇到模架导柱组装精度的检查这个难题,用一般宽座角尺或样板角尺检查时,均不易测准垂直度误差,为此制作了如图示简易垂直度比较仪,用来检验各种模架导柱垂直度。有标准圆柱角尺时,采用与圆柱角尺对比的比较量法,如没有角尺,则采用被检测件自身各对应点互相比较的自检方法,来确定各方向上的垂直度误差。为了提高测量精度并使量具本身结构简单,本仪器采用无动件。检测工件之前,先用标准圆柱角尺将
I workshop for many years in the processing of assembly molds, mold assembly guide column assembly often encountered the problem of checking the accuracy of the general wide-angle square or sample square ruler inspection, are not easy to measure verticality error, for which the production of simple as shown Verticality comparator, used to test a variety of mold guide column verticality. When there is a standard cylindrical square, the comparison method with the cylindrical square is used. If there is no square, the self-test method of comparing each corresponding point of the tested piece with each other is used to determine the verticality error in each direction. In order to improve the measurement accuracy and the measuring device itself is simple, the instrument uses no moving parts. Before testing the workpiece, use a standard cylindrical square
