Single-axis double-sensor type parallelism detection device and method thereof

The invention belongs to the technical field of metering testing, and discloses a single-shaft double-sensor type parallelism detection device and a method thereof.The single-shaft double-sensor type parallelism detection device comprises a workbench, an air floating guide rail arranged in the vertical direction is arranged on the workbench, a left supporting arm extending leftwards is arranged on an air floating sliding block, and a left displacement sensor is connected to the left supporting arm in a left-right sliding mode; a right supporting arm extending rightwards is arranged on the air floating sliding block, and a right displacement sensor is connected to the right supporting arm in a left-right sliding mode. The device not only realizes measurement of plane parallelism and planeness and roughness of each plane, but also realizes measurement of cylindricity and verticality of a cylindrical surface. 本发明属于计量测试技术领域，公开了一种单轴双传感器式平行度检测装置及其方法，包括工作台，在工作台上设有沿竖直方向设置的气浮导轨，在气浮滑块上设有向左伸出的左支撑臂，在左支撑臂上左右滑动连接有左位移传感器；在气
