摘要: 針對(duì)鋼管常規(guī)測(cè)量切斜方法的可操作性與測(cè)量精度存在一定的局限性,設(shè)計(jì)出一款新型鋼管管端切斜測(cè)量尺。新型測(cè)量尺用千分尺代替了塞尺,安裝有水平調(diào)節(jié)裝置,千分尺鑲嵌在滑軌中,可在主尺上上下滑移,因此具有使用靈活方便,測(cè)量精度高等特點(diǎn),可用于實(shí)際測(cè)量。Abstract: The conventional methods for measuring out-of-squareness of the steel pipe as cut-off have some limitations in terms of maneuverability and measurement accuracy. Accordingly,a new type measurement scale for the same purpose is designed. Instead of the plug gauge,the new scale is in fact a micrometer attached with a leveling device. The micrometer is inserted into the sliding rail,and thus enabled to move up and down on the master scale. This structure makes the said new measurement scale featuring high operation flexibility and high measurement accuracy,being very practical.
