The invention relates to a circular spherical curvature surface concave disc level measuring instrument, which is composed of spherical curvature surface concave scale plate, glass ball, chassis, pressure plate, observation window and zero adjusting device, etc. Its features are as follows: the glass ball is a sphere, which is installed in spherical curvature surface scale plate, and the scale plate is fixed on the base of the chassis with bolt pressure plate; the spherical curvature surface shell scale plate is transparent; Material is made of a concentric circle calibration line from the zero calibration point to the center of the large circle of the spherical curvature surface at a fixed point of \0\ zero degree on the hemisphere; the zero adjustment device has two groups, which are set on the side of the base at 90 degrees; and the chassis chassis chassis chassis chassis chassis is a circular datum plane. The invention ingeniously utilizes the characteristics that the lightweight glass sphere automatically finds the lowest point and the lowest point of the hemispherical shell-shaped dial deviates from the 0-degree position of the hemispherical dial under the action of gravity, and uses the degree of the glass sphere deviating from the 0-degree position of the hemispherical dial to make the judgement of the deviation angle and direction of the measured plane horizontal degree.

一种圆形球曲率面凹盘式水平度测量仪
本专利技术涉及一种水平度测量工具,更确切地说涉及一种圆形球曲率面凹盘式水平度测量仪。
技术介绍
水平仪主要用于检验各种机床和工件的平面度、直线度、垂直度及设备安装的水平位置等;在设备安装或基建工程施工中,平面的水平度测量是保证施工质量的重要测量手段之一。目前,平面水平度的测量主要有以下几种方式:框式水平仪法、条式水平仪法、圆盘式水平仪法、经纬仪法、红外线水准仪法等,以上所有水平仪的水准管或基准找平管都是由玻璃制成,水准管内壁是一个具有一定曲率半径的曲面,管内装有液体;测量的原理为当水平仪发生倾斜时,水准管中气泡就向水平仪升高的一端移动,从而确定水平面的位置。上述水平仪由于自身的构造及特点,存在以下缺陷:1、因为水准器内液体对温度影响变化较大,手热、阳光直射、哈气等因素都会对对水平仪的影响;2、水准器的玻璃管内装液体有着一定的粘滞系数对测量精度也会产生一定影响;3、气泡读数的是估计估算,存在误差积累,准确性相对较差;4、还有玻璃器件使用时易被摔坏,不易调整、不易携带等缺陷。
