一种两坐标自动跟随式测量装置

论文就机械零件的相关尺寸的自动测量问题，提出了一种能实现两坐标自动跟随的测量装置。该装置由两层电动工作台和相应的传感器及测控电路组成，运动灵活，能快速跟随被测零件的尺寸变化，可广泛应用于工厂现场零件尺寸特别是相关尺寸的自动测量。该装置两个坐标方向的测量范围达到80mm(并可根据要求加长电动工作台的导轨，使测量范围进一步扩展），测量精度优于0．1％。当测量传感器离工件被测表面的距离为80mm时（最大），传感器跟踪到被测表面所需的时间为5秒。

A Sort of Two-coordinate Automatically-tracing Measuring Device

Concerning the automatic- measurement of the accessory's size,a sort of measuring device which can trace automatically in two directions is presented in this paper.The device is made up of double- deck electric worktable,sensor and circuit,which can move neatly and trace the change of the accessory's size fast. It can be used widely to measure the accessory's size in the process location,especially to measure automatically the corre- late size. The device's range in two coordinate directions in 80 mm (the measurement range can be enlarged by lengthening the guide) .The measuring precision of the device is excelled0 .1% .It will take the sensor5 seconds to trace the accessory's surface when the sensor is80 mm away from the measured accessory.
