本文所介绍的螺纹底孔检查和吹屑装置原理,即为一般的探针式检查和用压缩空气吹净底孔;但其特点是,可在同一工位顺次完成吹屑、检查孔深和攻丝,避免了一般检查装置需单独占用一个工位的缺点。探针的伸缩、转位和吹屑都用同一个压缩空气源进行,全过程均为自动,结构简单。 This article describes the thread bottom hole inspection and blow-off device principle, that is, the general probe-type inspection and blowing the bottom hole with compressed air; but its feature is that the same station in order to complete the blow-chip, check the hole depth And tapping, to avoid the general inspection device requires a separate occupation of the shortcomings. Probe telescopic, translocation and blowing debris are the same source of compressed air, the whole process is automatic, simple structure.
