Comprehensive gauge for deep blind hole

The utility model relates to a deep blind hole comprehensive gauge which comprises a measuring body used for being placed in a deep blind hole to be measured, the outer contour of the measuring body is matched with the shape of an inner hole of the deep blind hole to be measured, the rear end of the measuring body is detachably provided with a measuring rod through a mounting plate, scales are engraved on the measuring rod, and the measuring rod is connected with the measuring body. And the measuring rod is also connected with a reference plate in a sliding manner. Therefore, the problems that the shape, depth and other parameters of the arc section in the hole are difficult to accurately and quickly measure in the machining process of an existing deep blind hole testing fixture, and machining and subsequent assembly are affected are solved. 本实用新型涉及一种深盲孔综合量规，包括用于放入被测深盲孔内的测量体，所述测量体的外轮廓与待测深盲孔的内孔形状匹配，所述测量体后端通过安装板可拆卸地安装有测量杆，所述测量杆上刻有刻度，且所述测量杆上还滑动连接有基准板。如此，解决了现有的深盲孔检具在加工过程中难以准确、快速地测量孔内弧段的形状和深度等参数、对加工以及后续的装配产生影响的问题。
