The utility model relates to a measuring device for the distance between two holes or between holes and side lines, which is characterized by: a guide sleeve, a cone head, an adjusting screw and a compression spring. The guide sleeve consists of a conical guide block and a measuring block, which forms an integral guide sleeve body with L-shaped longitudinal cross section. The Center of the conical guide block is provided with a step hole, and the upper end of the step hole is provided with internal threads and internal threads. Connected with the adjusting screw, the lower end hole of the step hole is provided with a conical chamfer, the sliding part of the step hole is matched with a conical head, and the cone of the conical head matches the conical chamfer of the step hole. A compression spring is arranged between the adjusting screw and the conical head. Beneficial effect: The utility model has the advantages of simple structure, convenient manufacture, accurate and reliable positioning, compact and portable volume, flexible measurement mode, and can be used with existing measuring tools, and is suitable for hole distance measurement with accuracy not exceeding 0.1 mm. Especially, it can measure the distance between the hole in sheet metal and other holes or between the hole and the edge line quickly, accurately and reliably.
【技术实现步骤摘要】
两孔间距或孔与边线间距的测量装置
本技术属于测量领域,尤其涉及一种两孔间距或孔与边线间距的测量装置。
技术介绍
工人在车间内进行试制零件或者零件检验时,经常会遇到测量孔与孔之间或是孔与边线之间间距的情况。一般是进行两次测量;第一次利用游标卡尺卡住孔边与另一条边线进行测量,记为a,第二次测量孔直径,记为b,再将两次测量结果按a+b/2进行计算得到结果。由于需要进行两次测量,且两次测量都有存在误差的可能,所以这种测量方法准确度欠佳也不够方便。此外还极易出现因为游标卡尺刃口没有卡紧孔边导致的测量不准情况,使得测量不具有可靠性。目前测量方法是在游标卡尺基础上,将两个刀形测量刃口改为圆锥形,利用锥形头定位,通过在尺上读出数字进行测量。其缺点在于测量过程中锥形头容易歪斜,锥面与孔的接触不稳定,导致操作时需要测量者施力保持住尺子姿态,在比较狭小或是操作受限的空间中操作极为不便,测量过程中的测量者手部动作的晃动,也会使测量出的结果不具有可靠性,误差较大。此外,为测量孔距需要单独配带一把专用卡尺,专用卡尺除测量孔距之外不能测量其他尺寸,功能单一,也导致了该专利技术推广起来较为不便。 ...
