In the machinery industry and instrument manufacturing, it is used to measure the inclination angle relative to the horizontal position, the flatness and straightness of the guide rail of machine tool equipment, the horizontal position and vertical position of equipment installation, etc. According to the shape of the level, it can be divided into: universal level, cylindrical level, integrated level, mini level, camera level, frame level, ruler level; according to the fixing method of the level, it can be divided into: adjustable level and Non-adjustable spirit level.
目前市面上常见的水平仪主要有基于单片机的电子式水平仪以及气泡电容式水平仪等。电子式水平仪的工作原理主要基于电感原理,即:当水平仪的基座因待测工件倾斜而倾斜时,其内部摆锤因移动所造成感应线圈的电压变化。电容式水平仪其测量原理为一圆形摆锤自由悬挂在细在线,摆锤受地心重力所影响,且悬浮于无摩擦状况。摆锤的两边均设有电极且间隙相同时电容量是相等,若水平仪受待测工件所影响而造成,两间隙不同距离改变即产生电容不同,形成角度的差异。At present, the common levels on the market mainly include electronic levels based on single-chip microcomputers and bubble capacitive levels. The working principle of the electronic level is mainly based on the principle of inductance, that is, when the base of the level is tilted due to the inclination of the workpiece to be measured, the voltage of the induction coil caused by the movement of the internal pendulum will change. The measurement principle of the capacitive level is that a circular pendulum hangs freely on a thin wire. The pendulum is affected by the gravity of the center of the earth and is suspended in a frictionless state. There are electrodes on both sides of the pendulum and the capacitance is equal when the gap is the same. If the level is affected by the workpiece to be measured, the different distances between the two gaps will produce different capacitances and angle differences.
电子式水平仪具有测量精度高的优点,但是技术工艺复杂,生产精度要求较高,因此成本较高;气泡电容式水平仪,成本低,易加工,但是测量精度较低;因此本实用新型结合两者的优点,设计出一种新型的电磁式水平度测量装置,既能满足精度要求,又能降低了成本。The electronic level has the advantage of high measurement accuracy, but the technical process is complicated and the production accuracy is high, so the cost is high; the bubble capacitive level is low in cost and easy to process, but the measurement accuracy is low; therefore, the utility model combines the two Based on the advantages, a new type of electromagnetic levelness measuring device is designed, which can not only meet the accuracy requirements, but also reduce the cost.
