对一般有测量轴的量仪,都有一项轴杆与孔间隙的检定要求,以保证测杆径向窜动对示值的影响不会超过允许的数值。我们自制了一种简易径向窜动检具,经过几年来的使用,效果较好。它具有结构简单,易于制造,使用方便,携带轻巧等优点,特别适用于下厂检修量仪时使用。检具结构如图1所示,用自行车车条紧装一手 For measuring instruments that generally have a measuring axis, there is a test requirement for the clearance between the shaft and the hole to ensure that the influence of the radial movement of the measuring rod on the indication does not exceed the allowable value. We made a simple radial movement gage, after several years of use, the effect is better. It has a simple structure, easy to manufacture, easy to use, lightweight and so on, especially suitable for use when the next plant overhaul meter.
