水平仪是常用测量小角度一种普通量具,用于检验各种机床及其它类型设备导轨的平直度和设备安装的水平位置和垂直位置。水平仪是用水准管中的气泡两端边沿在水准管上刻度的位置来读数的,为了保证读数的准确可靠,首先必须保证水平仪的零位正确。常见几种可调式水平仪的零位调整方法是:1.对于托板螺杆式结构的水平仪:将此水平仪角尺面上的圆盖板打开,就可以见到一套螺丝调节装置(见图1示意图)。首先用专用
Level is commonly used to measure a small angle of a common measuring instrument used to test a variety of machine tools and other types of equipment, flatness and equipment installation of the horizontal position and vertical position. Level instrument is used in the level of the bubble at both ends of the edge of the graduated level pipe to read the position, in order to ensure accurate and reliable readings, we must first ensure that the zero level of the instrument is correct. Several common zero level adjustment method of level adjustment method is: 1. Pallet screw structure of the level: the level of the angle ruler surface cover open, you can see a set of screw adjustment device (see Figure 1 Schematic ). First with a dedicated
