新型结构的深孔深度测量用检具

New Type of Measuring Device for Deep Hole Depth

新型结构深孔深度测量检具对于数量较大、规格相同的深孔深度检测具有明显优势,本文重点介绍了该检具的零件构成、结构特点、构成件的加工制造要求、测量原理及操作流程。该检具不仅能快速准确地检测出深孔深度是否满足公差要求,还能检测深孔深度的实际值,为超差孔返修提供尺寸依据。

A new type of deep hole depth measuring device is proposed,which has obvious advantages over other detectors for the detection of large quantity and same size of deep hole.The composition of the detector,the structural characteristic the manufacturing requirements of components,the measuring principle and the operation flow are introduced emphatically.The detector not only can quickly and accurately detect whether the depth of the deep hole meets the tolerance requirements,but also can detect the actual value of the depth of the deep hole,thus providing the size basis for the over differential hole repair.
