在检验内锥度要求较高的零件时,一般采用万能游标量角器,但由于某些零件内锥基准面太窄或孔径太小而无法测量,操作者在加工中也无法掌握锥度的变化。若用涂色法,则因显示剂厚薄不均,转动摇晃等主观原因容易造成假象,不适宜成批检验。 图1所示是我厂生产注塑机上的关键零件,内锥 In the inspection of taper demanding parts, the general use of universal cursor protractor, but because of some parts of the cone plane too narrow or too small diameter can not be measured, the operator can not control the taper in the process of change. If you use the coloring method, due to the display of uneven thickness, rolling and other subjective causes easily lead to illusion, not suitable for batch inspection.
