Abstract
本实用新型公开了一种便携式长双头螺栓同轴度测量工具,包括待测双头螺栓,待测双头螺栓同轴设置在套管内,套管一端同轴设置有安装孔,安装孔内设置有手轮;手轮包括转盘,转盘上同轴设置有第一锥螺纹套,第一锥螺纹套与双头螺栓上对应螺纹部配合;双头螺栓另一端悬空设置在套管外并在该端的螺纹部上设置第二锥螺纹套;所述套管外圆上安装有百分表,百分表的表头与第二锥螺纹套外圆接触。测量时,通过转动转盘,使被测双头螺栓转动一周以上,读出百分表在表侧锥螺纹套外圆上测得的最大跳动值,从而准确测量双头螺栓螺纹中径的同轴度数据,能满足工程现场便携测量的要求,结构简单,实用方便。
The utility model discloses a portable coaxiality measuring tool for long stud bolts, comprising a stud bolt to be measured, the stud bolt to be measured is coaxially arranged in a casing, one end of the casing is coaxially provided with an installation hole, and the installation hole A hand wheel is provided; the hand wheel includes a turntable, and a first tapered threaded sleeve is coaxially arranged on the turntable, and the first tapered threaded sleeve is matched with the corresponding threaded portion on the stud bolt; the other end of the stud bolt is suspended outside the casing and is in the A second tapered thread sleeve is arranged on the threaded portion of the end; a dial indicator is installed on the outer circle of the sleeve, and the head of the dial indicator is in contact with the outer circle of the second tapered thread sleeve. During measurement, rotate the turntable to make the stud under test rotate for more than one week, and read the maximum runout value measured by the dial indicator on the outer circle of the taper thread sleeve on the watch side, so as to accurately measure the coaxiality of the pitch diameter of the stud thread. It can meet the requirements of portable measurement on the engineering site, and has a simple structure and is practical and convenient.
