The utility model relates to a vernier for measuring hole spacing size and its use method, which belongs to the field of flat plate hole spacing measurement, and overcomes the defects of large workload and large error in measuring with tape gauge in the prior art. Its structure includes: main ruler (1), vernier ruler (2), claw (2), fixed screw (2); main ruler (1) middle slot, vernier ruler (2) lower end has a convex platform, the convex platform inserted into the main ruler (1) middle slot, in a sliding state; vernier ruler (2) and claw (3) can be fixed on a certain position of the main ruler (2) by tightly fixing the screw (4). . When in use, the left vernier scale_ \0\ and the main ruler scale_are aligned with the diameter and size of the hole on the detected workpiece board_; and the two claws_are inserted into the middle part of the two measured holes on the tested workpiece board_and clamped; the main ruler reading indicated by the right vernier is the distance between the two measured holes. The invention is widely applicable to measuring the distance between two holes on the flat plate. Especially in the measurement of the hole distance of the connecting plate in large quantities, it is flexible and convenient, with high measuring accuracy and high working efficiency.

一种孔距尺寸检测游标尺及使用方法
本专利技术属于压力容器检测量具领域,涉及塔器连接板孔距测量。
技术介绍
在塔器连接板测量工作中,由于连接板数量大、尺寸规格多,测量比较困难,现有技术只能用卷尺进行测量,工作量大,浪费时间,且测量误差较大。
技术实现思路
专利技术的目的是为了克服现有技术中存在的问题,提供一种平板上孔距尺寸检测游标尺。一种孔距尺寸检测游标尺,其结构有:主尺1、游标尺2两个、卡爪3两个、固定螺钉4两个;主尺1中间开长槽,游标尺2下端有凸台,凸台高度小于主尺1厚度,该凸台与主尺1中间长槽紧密配合;游标尺2下端凸台插入主尺1中间长槽,处于可滑动状态;可以通过固定螺钉4将游标尺2和卡爪3固定在主尺1一定位置上。孔距尺寸检测游标尺的使用方法如下:1)选择合适量程的主尺;2)将左游标尺2“0”刻度和主尺1上与被检测工件板5上孔直径尺寸刻度对准;3)拧紧左固定螺钉4;4)将两个卡爪3穿入被检测工件板5两个被测量孔中间部位并夹紧;5)拧紧右固定螺钉4;6)右游标尺指示的主尺读数即为两被测量孔孔距尺寸。本专利技术的有益效果是:广泛适用于平板上两孔之间的孔距测量。特别在大批量塔器内件等连接板孔距的测量时,灵活方便,测量精度高,工作效率高,降低了检测人员的劳动强度。附图说明图1为一种孔距尺寸检测游标尺检测主视图,图2为一种孔距尺寸检测游标尺检测俯视图,图3为一种孔距尺寸检测游标尺左剖视图,图4为一种孔距尺寸检测游标尺读数示意图,图中:1主尺、2游标尺、3卡爪、4固定螺钉、5被检测工件板。具体实施方法:专利技术提供了一种孔距尺寸检测游标尺,如附图图1、图2所示,其结构有 ...
